Desarrollo de un índice de integridad biológica avifáunico para los humedales de la reserva de la biosfera pantanosa de Centla, Tabasco
Provedor de dados: 32
Autores: Córdova Avalos, Antonio.
Se evaluó la salud de los Pantanos de Centla, Tabasco, mediante un índice de  integridad biológica (IBI) utilizando a las aves como indicadoras. Se seleccionaron sitios de  manglar y popal-tular con diferente grado de perturbación (conservado, semiconservado y  perturbado). Un análisis de cambio de cobertura con imágenes de satélites Landsat MSS 1976  y ETM 2002 mostró pérdidas de cobertura de manglar de 21─31 % y tasas de deforestación  anual de 0.8 ─ 1.2 %. El registro histórico de especies de aves fue de 328, detectándose 189  en este estudio, de las cuales 13 fueron nuevos registros para la Reserva. Se encontraron  diferencias significativas en el número de especies entre sitios (α=0.05). De acuerdo con el  estimador de cobertura basado en abundancias,...

Nature vs. Nurture: the Making of the Montado Ecosystem
Provedor de dados: 7
The southern Iberian Peninsula is dominated by a savannah-like ecosystem, the montado, which is a typically Mediterranean cultural adaptation to generally poor productive areas. Montados are exploited for three main uses: forestry, agriculture, and extensive grazing, in proportions that vary according to local conditions (more or less productive land) and historical circumstances. Because these ecosystems occur over a large geographic area (they occupy some 6 million ha), biodiversity would be expected to vary among montados. However, differences in management practices may also influence species distribution. In this paper, we investigate differences in plant and bird species diversity among 60 montados distributed all across southern Portugal. The...

Scaling of Natal Dispersal Distances in Terrestrial Birds and Mammals
Provedor de dados: 7
Autores: Sutherland, Glenn D; University of British Columbia; gsland@interchg.ubc.ca; Harestad, Alton S; Simon Fraser University; harestad@sfu.ca; Price, Karen; Simon Fraser University; kprice@futurenet.ca; Lertzman, Ken; Simon Fraser University; lertzman@sfu.ca.
Natal dispersal is a process that is critical in the spatial dynamics of populations, including population spread, recolonization, and gene flow. It is a central focus of conservation issues for many vertebrate species. Using data for 77 bird and 68 mammal species, we tested whether median and maximum natal dispersal distances were correlated with body mass, diet type, social system, taxonomic family, and migratory status. Body mass and diet type were found to predict both median and maximum natal dispersal distances in mammals: large species dispersed farther than small ones, and carnivorous species dispersed farther than herbivores and omnivores. Similar relationships occurred for carnivorous bird species, but not for herbivorous or omnivorous ones....

We review characteristics of birds in boreal forests in the context of their ecological sustainability under both natural and anthropogenic disturbances. We identify the underlying ecological factors associated with boreal bird populations and their variability, review the interactions between boreal bird populations and disturbance, and describe some tools on how boreal bird populations may be conserved in the future. The boreal system has historically been an area with extensive disturbance such as fire, insect outbreaks, and wind. In addition, the boreal system is vulnerable to global climate change as well as increasing pressure on forest and water resources. Current knowledge indicates that birds play an important role in boreal forests, and...

Collisions between aircraft and birds, so-called &amp;#8220;bird strikes,&amp;#8221; can result in serious damage to aircraft and even in the loss of lives. Information about the distribution of birds in the air and on the ground can be used to reduce the risk of bird strikes and their impact on operations en route and in and around air fields. Although a wealth of bird distribution and density data is collected by numerous organizations, these data are not readily available nor interpretable by aviation. This paper presents two national efforts, one in the Netherlands and one in the United States, to develop bird avoidance nodels for aviation. These models integrate data and expert knowledge on bird distributions and migratory behavior to provide hazard...

Indirect assessment of seed dispersal effectiveness for Solatium riparium (Solanaceae) based on habitat use and rate of fruitdisappearance
Provedor de dados: 67
Autores: Lomascolok,Silvia Beatriz.
The ability of a plant's propagule to reach microhabitats with the adequate conditions for seed germination and sapling establishment will have a direct effect on the plant's fitness. In the case of fleshy-fruited plants, the seeds are dispersed by frugivorous animals. One part of the seed dispersal process is the removal of the fruits, which contain the seeds, from the parental plant. Another important part of the dispersal process is where the seeds land, especially for species with specific light, temperature or humidity needs for germination, such as disturbance colonizers. Solanum riparium (Solanaceae) is a shade intolerant species found in forest gaps within a subtropical montane forest and along river and road edges in North-western Argentina. In...

The effects of habitat heterogeneity on avian density and richness in soybean fields in Entre Ríos, Argentina
Provedor de dados: 68
Autores: Goijman,Andrea P.; Zaccagnini,María Elena.
Birds play several roles in agricultural lands and respond to habitat heterogeneity within the agricultural landscape. Agricultural intensification in Argentina has increased the sown area, mainly with soybean, fragmenting landscapes in the pampas and mesopotamic region. In Entre Ríos Province, the original Espinal forest has been fragmented, leaving remnant patches of natural vegetation, in cases modified by cattle grazing. These changes represent a potential threat for avian conservation. In Entre Ríos, terraces may be a useful habitat in maintaining avian diversity, similar to other non-cropped linear habitats in agricultural landscapes. We tested the hypothesis that habitat heterogeneity created by terraces would maintain higher species richness and...

Abstract An extensive karyotype variation is found among species belonging to the Columbidae family of birds (Columbiformes), both in diploid number and chromosomal morphology. Although clusters of repetitive DNA sequences play an important role in chromosomal instability, and therefore in chromosomal rearrangements, little is known about their distribution and amount in avian genomes. The aim of this study was to analyze the distribution of 11 distinct microsatellite sequences, as well as clusters of 18S rDNA, in nine different Columbidae species, correlating their distribution with the occurrence of chromosomal rearrangements. We found 2n values ranging from 76 to 86 and nine out of 11 microsatellite sequences showed distinct hybridization signals among...

Abstract Zonotrichia capensis is widely distributed in the Neotropics. Previous cytogenetic studies demonstrated the presence of polymorphisms in two chromosome pairs (ZCA2 and ZCA4). Here, we report results based on comparative chromosome painting, using probes derived from Gallus gallus and Leucopternis albicollis, focused on characterizing the chromosome organization of Z. capensis. Our results demonstrate the conservation of ancestral syntenies as observed previously in other species of passerine. Syntenies were rearranged by a series of inversions in the second chromosome as described in other Passeriformes, but in this species, by using probes derived from L. albicollis we observed an extra inversion in the second chromosome that had not previously...

The karyotype of the critically endangered Lear's macaw, Anodorhynchus leari Bonaparte 1856 (Aves, Psittaciformes)
Provedor de dados: 74
Autores: Nogueira,Denise Monnerat; Souza,Lucia Moreno de; Goldschmidt,Beatriz; Silva,Christiano Pinheiro da; Monsores,Denise Wilches.
We used conventional chromosomal staining to describe the karyotype of the critically endangered Lear's macaw, Anodorhynchus leari Bonaparte 1856. A diploid number of 2n = 70 and a karyotype similar to that of its congener Anodorhynchus hyacinthinus suggests that chromosomal rearrangements were not the main evolutionary mechanism in the genus.

Autores: Valente,Renata de Melo.
Fourteen bird species were observed visiting one specimen of Alchornea glandulosa Poepp., 1845, at the Horto Florestal Navarro de Andrade, Rio Claro, São Paulo State, Brazil. Among them, three species seem to be the most efficient seed dispersers of A. glandulosa at the study site: Myiodinastes maculatus (Müller, 1776), Empidonomus varius (Vieillot, 1818) e Tyrannus melancholicus Vieillot, 1819. Besides to swallow fruit whole, these birds contributed with 68.5% of the total feeding visits. A. glandulosa fruit are not the mainly part of the diet of any one of the observed bird species, since they do not fit in the frugivorous specialized category. However, as almost all the observed individuals swallow fruit whole, it is suppose that they promote an...

Autores: Monnat, J.y.
Immediatly following the AMOCO CADIZ oil spill, the S.E.P.N.B. carried out health centers for oiled birds from Finistère, and estimated the impact of the oil spill on seabirds. In the whole, 15 to 20 000 birds are dead because of the AMOCO CADIZ oil spill. 41 species have been oiled, among which 35 usually live in marine environment. The species most stressed belong to alcidae. The mortality rate (0,1 bird/ton of oil) seems to be, at. present day, the lowest rate never mentionned in the litterature.

Aim The assessment of biodiversity patterns under global changes is currently biased towards taxonomic diversity, thus overlooking the ecological and functional aspects of species. Here, we characterized both taxonomic and functional diversity of insular biodiversity threatened by multiple threats. Location Worldwide islands (n = 4,348). Methods We analysed the relative importance of eleven major threats, including biological invasions or climate change, on 2,756 insular endemic mammals and birds. Species were functionally described using five ecological traits related to diet, habitat and body mass. We computed complementary taxonomic and functional diversity indices (richness, specialization, originality and vulnerability) of species pools affected by...

Nothura maculosa is a South American Tinamidae with a marked seasonal reproductive pattern. This work describes ovarían seasonal changes in this species related to gonadotrope (GTHs) population. Ovary and pituitary samples were collected monthly from adult birds during four annual periods. They were fixed in Bouin's solution and processed for light microscopy. The data of post-fixation gonadal weight were analysed using STATISTIX 4.0. Histological sections of the ovaries were stained with H/E, PAS and Goldner-Masson trichrome. Single and double immunostaining were applied on pituitary sections with anti-chicken-FSH and anti-chicken-LH antibodies. The samples were analysed in quarterly periods of the year, Pl: March-May (resting stage); P2: June-August...

Dawn chorus variation in East-Asian tropical montane forest birds and its ecological and morphological correlates
Provedor de dados: 16
Autores: Chen, W.-M.; Lee , Y.-F.; Tsai, C.-F.; Yao, C.-T.; Chen, Y.-H.; Li, S.-H.; Kuo, Y.-M.
Many birds in breeding seasons engage in vigorous dawn singing that often turns to a prominent chorus. We examined dawn chorus variation of avian assemblages in a tropical montane forest in Taiwan and tested the hypothesis that onset sequence is affected by eye sizes, foraging heights, and diet of birds. Chorus onset and duration varied between sampling months, but generally peaked in the prime breeding season. Overall dawn chorus length increased with, but mean duration per species was negatively correlated with, species richness. The inter-correlation among trait variables in phylogenetic independent contrasts was calculated and examined. Both foraging height and relative eye size were selected as positively explanatory factors, but no dietary effects...

The avifauna of the island of Flores (Lesser Sunda Islands) is reviewed. Introductory sections, which include a chapter on the history of ornithological discovery, are followed by the main part, a systematic account in which each species and subspecies known from Flores is treated separately. A discussion of the zoogeography, a gazetteer, a list of references and an index complete the volume. At present 214 forms (210 species) are accepted as having been reliably recorded. Of these, ca. 160 are, or may be assumed to be, residents, and of ca. 100 the eggs have been collected and are described. The balance consists of visiting sea and freshwater birds, migrants from the North and migrants from the South. It is likely that few additions remain to be made to...

Provedor de dados: 16
Autores: Dickinson, E.C.; Walters, M.P.
McClelland brought back specimens and drawings from a survey in 1835-36 (and perhaps 1836-37). New birds were described in a paper read by Horsfield (1840). A comparison of the McClelland drawings of birds, held at the British Library, with the type specimens of birds newly named in 1840 and with other material has shown that McClelland’s collection was not fully reported. McClelland actually recorded about 170 species not just 96 as then listed. Some birds listed in 1840 were misidentified, of these some have been corrected earlier but at least one is here newly considered and looks as if it needs further correction. Taxonomic and nomenclatural notes are included when necessary. The correct name to apply to the one species in the genus Melanochlora, the...

Au cours d’une mission du N/O N’Diago en juin 1987, des observations ont été réalisées sur le peuplement ornithologique présent à cette époque au large des côtes mauritaniennes. 17 espèces marines ont été recensées qui sont pour la plupart des sub-adultes non nicheurs de l’air Paléarctique (par exemple &lt;Chlidonias niger&gt;, &lt;Sterna hirundo&gt;, &lt;Calonectrice diomedea&gt;) soit des nicheurs de l’hémisphère austral en hivernage (par ex. &lt;Oceanites oceanicus&gt;). Une estimation semi-quantitative des effectifs montre que ces 4 espèces composent l’essentiel du peuplement. Les navires de pêche jouent à leur égard un rôle important sur le plan alimentaire par les déchets des poissons rejetés à la mer mais aussi pour la satisfaction des autres...

Habitat verlies en degradatie is één van de belangrijke ecologische problemen van deze eeuw. Hoewel alle ecosystemen hieronder te lijden hebben, blijken wetlands of waterrijke gebieden, op wereldschaal vrij zeldzame gebieden, onder zeer zware antropogene druk te staan. Het is daarom ook niet te verwonderen dat deze ecosystemen sinds meerdere jaren een belangrijke prioriteit vormen voor het natuurbehoud. Binnen de wetlands vormen estuaria zeer produktieve systemen waarvan het rijke voedselaanbod wordt benut door grote aantallen steltlopers, die buiten het broedseizoen bijna volledig op dergelijke getijdengebieden zijn aangewezen. Het belang van het Deltagebied (NI.) en met name de getijdengebieden van Ooster- en Westerschelde voor watervogels worden kort...

First avifaunal survey of a Cerrado dry forest enclave on the right bank of the São Francisco River, Minas Gerais, Brazil, with insights on geographic variation of some species
Provedor de dados: 84
Autores: Vasconcelos,Marcelo Ferreira de; D’Angelo Neto,Santos.
Abstract Cerrado dry forest enclaves have been treated as an endemic bird area. In the last years, some avifaunal surveys have been conducted in dry forests on the left bank of the São Francisco River, eastern Brazil. Nevertheless, there is a gap of detailed ornithological surveys in the Cerrado dry forest enclaves on the right bank of this river. Here, we present the first avifaunal survey of a Cerrado dry forest enclave on the right bank of the São Francisco River. The study area, named “Curral de Pedras”, comprises a dry forest enclave and other associated habitats in central Minas Gerais state, southeastern Brazil. We recorded 172 bird species; nine taxa have their ranges strongly associated to the Caatinga; six present their ranges associated to the...

Autores: Tisdell,   Clement A.; Wilson,   Clevo.
Lamington National Park in Queensland, Australia is noted for its rainforest and is part of Australia’s fourteen World Heritage listed properties but no systematic study has been done of the importance of birds to its visitors.  This study rectifies this situation.  It is based on data from survey forms handed to visitors at an important site in this park and completed by visitors following their visit.  This yielded 622 useable replies.  These enabled us to establish the comparative importance of birds as an attraction to this site. Furthermore, logit regression is used to analyze and to identify factors that increase the likelihood of a visitor saying that birds are an important attraction.  In addition, the relative importance to visitors of various...

Autores: Rocha,PMC; Barros,MEG; Rocha,BP; Souza,FAL; Mendonça,FS; Evêncio-Neto,J.
ABSTRACT This paper describes the epidemiological, clinical and pathological aspects of an avian encephalomyelitis (AE) outbreak in commercial laying hens in Northeastern Brazil. The disease affected 23,409 layers (from day one until 100 weeks) leading to mortality of 16.5% (5,049/30,600) of the flock. Twenty laying hens were clinically examined, and blood samples were collected and tested by Enzyme-Linked Immunosorbent Assay (ELISA). Five laying hens with neurological signs were necropsied and samples of the brain, cerebellum, spinal cord, sciatic nerve, heart, ceca tonsils, proventriculus and liver were collected, fixed in formalin buffered solution and processed according to routine methods for histological examination. Clinical signs were observed in...

Autores: Faria Filho,DE; Torres,KAA; Faria,DE; Campos,DMB; Rosa,PS.
This study evaluated the efficacy of probiotic utilization as growth promoters in broiler chicken feeding using systematic literature review and meta-analysis. Thirty-five studies were recovered by the systematic review, 27 of which met the following criteria to be included in the meta-analysis: (1) Brazilian studies published between 1995 and 2005; (2) probiotics administered in the diet without growth promoter; (3) results included performance data with the respective coefficient of variation. Meta-analysis have shown that the probiotics promoted better weight gain and feed conversion than the negative control (no antimicrobial) in the initial phase (1 to 20-28 days); nevertheless, results were similar in the total period (1 to 35-48 days). Weight gain...

Sex-dependent foraging effort and vigilance in coal-crested finches, Charitospiza eucosma (Aves: Emberizidae) during the breeding season: evidence of female-biased predation?
Provedor de dados: 103
Autores: Diniz,Pedro.
Sexual dimorphism in birds is often attributed to sexual selection, but another interpretation suggests the evolution of this phenomenon by natural selection. Predation may be an important selective pressure, acting mainly on females. In this study, I tested the latter hypothesis on the coal-crested finch (Charitospiza eucosma Oberholser, 1905) in a neotropical savanna of the Central Brazil (Cerrado). I used capture methods for ascertaining the sex ratio in the population, and focal observations to gather behavioral data. My results show that the sex ratio is skewed toward males (1:1.39). Males were more vigilant, vocalized for longer periods of time, and used higher perches than females. Females foraged more, spent more time on parental care and remained...

Blood metabolites as predictors to evaluate the body condition of Neopelma pallescens (Passeriformes: Pipridae) in northeastern Brazil
Provedor de dados: 103
Autores: Azeredo,Luane M.M.; Oliveira,Talita C.; Lopez,Luiz C.S.
ABSTRACT Body condition is an important ecological attribute that can provide a measure of the energy stored by an animal or population. Body condition is traditionally ascertained with morphometric body condition indices (BCIs), but some researchers have used various physiological and biochemical parameters as predictors of body condition. This study aimed to test reliable biochemical predictors of body condition in individuals of Neopelma pallescens (Lafresnaye, 1853), found in an Atlantic forest patch. For this purpose we examined the relationship between body condition and the concentrations of blood glucose and ketones. We also verified correlations between blood metabolite concentrations and ecological variables, including time of day, seasons,...

The use of the point count method for bird survey in the Atlantic forest
Provedor de dados: 103
Autores: Volpato,Graziele H.; Lopes,Edson V.; Mendonça,Luciana B.; Boçon,Roberto; Bisheimer,Maria V.; Serafini,Patrícia P.; Anjos,Luiz dos.
The point count method has been widely used in tropical forest for sampling bird communities. In the present study, we investigated if data on richness and abundance acquired using the point count method are different comparing spring/summer (breeding season) and fall/winter (non-breeding season) in three types of the Brazilian Atlantic forest. Twelve sites were sampled seasonally during one year. In general we recorded more species and individuals during the breeding seasons. However, bird communities vary seasonally among the forest types and functional groups. We demonstrate that the use of point counts in tropical forest should be adjusted considering the differences in forest types and feeding guilds.

Reproductive behavior of the Red-crested Finch Coryphospingus cucullatus (Aves: Thraupidae) in southeastern Brazil
Provedor de dados: 103
Autores: Zima,Paulo V.Q.; Francisco,Mercival R.
ABSTRACT Several behavioral aspects of the Red-crested Finch Coryphospingus cucullatus (Statius Müller, 1776) are poorly studied. Here we provide reproductive information on 16 active nests. This information may be valuable to elucidate the phylogenetic relationships of this bird, and to design plans to manage it. Nesting activities occurred from October to February. Clutches consisted of two to three eggs (2.06 ± 0.25), which were laid on consecutive days. Incubation usually started the morning the females laid their last egg and lasted 11.27 ± 0.47 days. Hatching was synchronous, or happened at a one-day interval. The nestling stage lasted 12 ± 0.89 days. Only females incubated the eggs and they fed the young more often than the males did. Overall...

Autores: Mallet-Rodrigues,Francisco; Parrini,Ricardo; Pimentel,Leonardo M. S.; Bessa,Rafael.
We studied the altitudinal distribution of 426 bird species in the Serra dos Órgãos, a mountainous region in southeastern Brazil. Thirty-four localities were visited between 1991 and 2009. Our study revealed a decline in bird species richness with elevation, although a smaller number of species was recorded at lower altitudes (below 300 m) possibly due to local extinctions caused by the intense human occupation of the region. A less diverse avifauna was found above 2,000 m, with only one species (Caprimulgus longirostris) recorded exclusively in this altitudinal range. Most endemic species were found between 300 and 1,200 m, but the endemism was more significant at higher altitudes. Nearly half of the birds found above 1,400 m were endemic species. Most of...

ABSTRACT Despite the fact that E. chlorotica (Linnaeus, 1766) is common and widely distributed in South America, the reproductive aspects of the species are poorly documented. Here we present data on 18 active nests found from August to February, between 2007 and 2012. Nests were globular with a lateral entrance, and measured 97.9 ± 14.4 mm in outside height, 110.6 ± 11.6 mm in outside diameter, and were 4.88 ± 2.09 m above ground. They were often supported from bellow and were composed mainly of tiny dry leafs and leaflets, fine petioles, and plumed seeds, all compacted with spider web silk. Eggs were laid on consecutive days or with one day interval, and clutch size varied from 1-3 eggs (2.1 ± 0.6, n = 9 nests). Only females incubated the eggs, but both...

An experiment with 630 one-day-old chicks experimentally inoculated with Salmonella Typhimurium was performed to evaluate the effects of an organic acid blend (benzoic, fumaric and 2-hydroxi-4-methylltio-butanoic - HMTBa) on intestinal health and performance. The experimental challenge with Salmonella Typhimurium occurred in two different routes of administration: via crop on the first day after hatching, and via feed, offered from seven to 14 days of age. These groups were treated with organic acids in a 3 × 2 (agent versus acid) factorial arrangement. Chicks treated with organic acids had higher weight gain, mean live weight and better feed conversion at 14 days of age, and higher weight gain at 28 days of age. Chicks treated with organic acids...

Autores: Pomar,Candido; Kipper,Marcos; Marcoux,Marcel.
ABSTRACT Precise body composition measurements are essential in animal nutrition studies because the impact of treatments is evaluated based on changes in body weight and composition. Various indirect techniques for animal compositional evaluation have been developed and evaluated for applicability in animal nutrition studies. A fast, accurate, minimally invasive method that requires little input is considered the ideal for providing information about the animal. Measurements obtained by dual-energy x-ray absorptiometry (DXA) are highly correlated with those obtained by chemical analysis and dissection. The algorithms of DXA software partition the six chemical components of the body (lipids, water, proteins, carbohydrates, non-bone mineral, and bone...

Testing the role of contaminants in depressing avian numbers
Provedor de dados: 97
Autores: KARASOV,WILLIAM H.; MEYER,MICHAEL W.
Environmental contaminants are ubiquitous and so are often key suspects in cases of lagging wildlife populations. How do we test hypotheses about cause-effect linkages between contaminants and wildlife health? We present three case studies in which different approaches were used to test hypotheses about effects of contaminants on wildlife. The cases involve the possible impacts of (1) polychlorinated biphenyl on Lake Superior bald eagles (Haliaeetus leucocephalus); (2) dioxin on osprey (Pandion halieatus); and (3) methyl mercury on common loons (Gavia immer). The different approaches were dictated by legal, logistic, and financial limitations, but the relative strengths of experimental and mechanistic approaches over correlative approaches is underscored....

Differential effects of habitat fragmentation on birds and mammals in Valdivian temperate rainforests
Provedor de dados: 97
Autores: KELT,DOUGLAS A.
Four recent studies on Chilean vertebrates underscore the very different effects that habitat fragmentation may have under different conditions. In southern Chile, birds exhibited significant species-area relationships, whereas the more depauperate small mammal community did not. The avifauna of highly isolated rainforest remnants in Fray Jorge National Park (IV Región) presented steeper species-area relations than those in southern Chile, reminiscent of land-bridge islands after faunal relaxation. The small mammal results were unexpected but may reflect the reduced vagility and immigration potential of this group. Additionally, the inter-remnant matrix habitat may support large populations of only some species, allowing them to capitalize on resources...

Since 1989, we have conducted a large-scale ecological experiment in semiarid thorn scrub of a national park in north-central Chile. Initially, we focused on the role of biotic interactions including predation, interspecific competition, and herbivory in small mammal and plant components of the community. We utilized a reductionist approach with replicated 0.56 ha fenced grids that selectively excluded vertebrate predators and/or larger small mammal herbivores such as the degu, Octodon degus. Although we detected small transitory effects of predator exclusions on degu survival and numbers, other species failed to show responses. Similarly, interspecific competition (i.e., degus with other small mammals) had no detectable numerical effects (although some...

Avian adjustments to desert environments are characterized by an integration of behavior and physiology. These responses serve to maintain homeostasis and conserve vital resources such as water. The small size of birds confers a close coupling to the thermal environment and demands rapid adjustments to environmental challenges. Physiological responses to heat stress include hyperthermia, and increased evaporative cooling as environmental temperatures approach body temperature. Behaviorally, desert birds respond to heat stress by drastically reducing activity during the hottest parts of the day and selecting cool shaded microsites. This characteristic behavioral response presents a potential problem in the face of global warming. If birds totally forgo...

Effects of forest heterogeneity on occurrence and abundance of the scale-backed antbird, Hylophylax poecilinotus (Aves: Thamnophilidae), in the Amazon forest
Provedor de dados: 104
Autores: Cintra,Renato; Cancelli,Jessica.
Recently, a significant number of studies on neotropical forest bird communities have focused on factors influencing their richness, abundance, and habitat selection. However, few of them have considered populations or individual species, and how habitat structure affects their distribution and abundance. In this study, we investigated how the combined effects of some forest structure components affect the occurrence and abundance of a resident bird species, the scale-backed antbird Hylophylax poecilinotus (Cabanis, 1847). We tested the null hypothesis of no difference between the variation in forest structure components at locations where birds occurred and at locations where they did not. In a pristine Terra Firme forest at the Ducke Reserve, Manaus, we...

Provedor de dados: 104
Autores: Duca,Charles; Marini,Miguel Â.
For colonial bird species, egg hatching synchrony has been considered an important factor in their reproductive success. The Red-rumped Cacique, Cacicus haemorrhous (Linnaeus, 1766), is a Passeriformes species (Icterinae) that reproduces in colonies in which groups of females lay their eggs at different periods during the reproductive season. The objective of this study was to evaluate if there was a variation in the reproductive success among C. haemorrhous females groups that lay eggs in different periods along the reproductive season. A total of 192 nests from four colonies were monitored at Parque Estadual do Rio Doce, Minas Gerais state, Brazil, and used to calculate the nest survival probability in different periods (early and late) of the 2001...

Aves de três remanescentes florestais do norte do Estado do Paraná, sul do Brasil, com sugestões para a conservação e manejo
Provedor de dados: 104
Autores: Bornschein,Marcos Ricardo; Reinert,Bianca Luiza.
One hundred eighty species in a preliminary inventory were identified. From these, 166 were in an area of 832.5 ha (Mata São Francisco State Park), 84 in another of 9.7 ha (Manoel Júlio de Almeida Municipal Forest) and 99 in the third remnant, briefly sampled, of 218 ha (Mata São Paulo). Comparing these numbers to inventories of nearby sites was considered that the larger area is poor in number of bird species, and believe this to be mainly due to the high degree of environmental degradation. Was considered that the smaller area is rich in birds, but its proximity (375 meters) to the third remnant certainly exeits strong influence. This paper presents the list of birds by site and with their relative frequency of occurrence. A new record for Paraná...

Ascocotyle (Phagicola) rara sp. n. is described from the intestine of Ixobiyclius exilis (Gmelin, 1789), a Brazilian bittern. The new species is compared with Ascocotyle (Phagicola) angeloi Travassos, 1928 and Ascocotyle (Phagicola) moUieiiisicola (Sogandares-Bernal &amp;amp; Bridgman, 1960); the main distinguishing characters are related to the aspect of the gonotyl that is not perforated in A. (P.) rara sp. n. when compared to A. (P.) mollienisicola and the absence of the crown of spines at the anteriorend in the new species compared withA. (P.) angeloi. This is an important finding, since human infections by Phagicola spp. have been previously reported in Brazil.

Known as "domestic dove", the Columba livia (Gmelin, 1789) is a columbidae species widely distributed in Brazil, whose reproductive biology has been studied by many researchers. The testes of 12 Columba livia males were collected and prepared for histologic examination under an optical microscope, the results of which were analysed and photographed. The tunica albuginea that covers the testes consists of a thick, not very cellular layer of dense connective tissue. Groups of interstitial cells with typical morphological appearance and surrounded by loose, well vascularized connective tissue are observable within the organ, between the seminiferous tubules. The seminiferous tubules are thick, intensely wound and, when seen in cross section, show Sertoli...

Provedor de dados: 36
Autores: GUILHERME,Edson; SOUZA,Izabele Rodrigues de.
ABSTRACT This study reports a successful reproductive event in Megascops choliba in eastern Acre, northern Brazil. An active M. choliba nest was monitored from the hatching of the eggs to the departure of the nestlings. Once hatched, the nestlings were weighed every two days to verify their weight gain over time. The nestlings remained in the nest for 30 days. The pattern of weight gain was similar to that found in other birds, presenting a rapid increase over the first 15 days, followed by a drastic reduction in the mean growth rate during the second half of the development period. Our observations indicate that the breeding season of M. choliba in southwestern Amazonia is similar as that reported for the species in the northern hemisphere. These are the...

Despite the striking association between the substitution of a Glutamic-acid by for a Lysine at position 92 on the MC1R protein and a completely black plumage, an in-depth understanding of the effect of missense mutations on the conformational change and behavior of the MC1R in the lipid bilayer caused by the absence of a crystal structure is lacking. We examine the structural basis for receptor activation using DNA sequences from the GenBank to perform in silico protein homology-based modeling. Our tridimensional model shows that the Alanine for a 179-Threonine substitution is a structural complement of the charge-reversing effect...

Collections of frozen tissue samples stand as keystone sources of molecular information to construct biodiversity knowledge, and are particularly challenged if they focus on megadiverse countries. In 1998 the Humboldt Institute (Instituto de Investigación de Recursos Biológicos Alexander von Humboldt) began a tissue collection of Colombian biodiversity (IAvH-CT) and the aim of this work is to present a diagnostic and an historical perspective for that collection, constructed by compiling information and experiences on its management as well as by organizing and curating the information of each catalogued sample. After 16 years, the IAvH-CT harbors 16,469 samples, which represent around 2530 species from 1289 genera, and 323 families of the Colombian...

Seed dispersal of Solanum thomasiifolium Sendtner (Solanaceae) in the Linhares Forest, Espírito Santo state, Brazil
Provedor de dados: 39
Autores: Vasconcellos-Neto,João; Albuquerque,Lidiamar Barbosa de; Silva,Wesley Rodrigues.
The aim of this study was to analyse seed dispersal and establishment of Solanum thomasiifolium in an area of "nativo" vegetation in Espirito Santo state on the southeastern Brazilian coast. Ten species of birds, the crab-eating fox (Cerdocyon thous), and one species of lizard (Tropidurus torquatus) fed on S. thomasiifolium fruits and dispersed viable seeds in their faeces. The proportional contribution of each of these groups to seed dispersal was 77% (birds), 19% (crab-eating fox) and 4% (lizards). Ants also contributed to seed dispersal. More seeds were deposited in vegetation islands than in the surrounding open areas. Germination rates of seeds collected directly from fruit (control), bird droppings, the faeces of crab-eating foxes and lizards were,...

Provedor de dados: 2
Autores: Araujo, Caroliny Costa; Rodrigues, Kênia Ferreira; Vaz, Roberta Gomes Marçal Vieira; Conti, Ana Carolina Muller; Amorim, Aline Ferreira; Campos, Carla Fonseca Alves.
The objective of this work was to identify, by means of different statistical criteria the ideal nonlinear regression model to describe the growth curve of three lineages of caipira broiler for meat production. A total of 90 birds were used, being 30 birds from each of the following lineages: Pescoço Pelado, Carijó and Pesadão Vermelho. The individual body weight of broilers (1, 7, 14, 21,28, 35, 42, 49, 56, 63, 70, 77, 84 and 91 days of age) was collected weekly for determination of growth curves by means of Models von Bertalanffy, Gompertz, Logistic, Richards and Brody. The parameters of Brody model did not converge to the weight of strains. The model that better adjusted to the data was Logistic.

Genetic and taxonomic relationships of five species of Rallidae (Aves: Gruiformes) based on mitochondrial cytochrome oxidase subunit I sequences
Provedor de dados: 2
Autores: Deef, Lamiaa Elsayed Mokhtar.
This is the first study to detection the genetic relationship between Porphyrio alleni and four Rallidae species: Fulica atra, Gallinulla angulata, Gallinulla chloropus and Porphyrio porphyrio. Mitochondrial cytochrome oxidase subunit I (COI) sequences were used as an effective marker in this study. DNA of Rallidae species were extracted, amplified using polymerase chain reaction (PCR) and then sequenced. The results obtained from information based on COI sequences revealed that Gallinulla angulata and Gallinulla chloropus fall into two separate clades and they are not monophyletic. This suggests that, two moorhens could not be laid into the same genus. In addition, Porphyrio porphyrio was included in the same genus with Porphyrio alleni but they were...

In northeastern Brazil, the reduction of the natural forest cover to a series of small, isolated fragments has had negative consequences for the local avian fauna, in particular, a loss of the more specialized species, while the populations of some generalists have tended to increase. The present study focuses on the composition and trophic groups of a bird community on a farm in the northeastern Brazilian state of Alagoas. Monthly surveys were conducted between November 2008 and October 2009, based on mist-netting and systematic observations. Overall, 112 species were recorded, of which 76 were associated with the two forest fragments surveyed, while all the others were observed exclusively in the surrounding matrix of pasture and orchards. The bird...

Bird community as an indicator of biodiversity: results from quantitative surveys in Brazil
Provedor de dados: 42
Autores: VIELLIARD,JACQUES M. E.
This short review presents the results obtained in several localities of Brazil on the composition of forest bird communities. Data were collected since the late 80's, after we introduced a new methodology of quantitative survey, based on acoustic identification and unlimited-radius point census. Although these data are still scattered, they show uniquely precise and coherently comparative patterns of composition of forest bird communities. Our methodology has the advantage of being absolutely non-disturbing, highly efficient in the field and immediately processed. Results confirm that the structure of a bird community is a good indicator of biodiversity, particularly useful where biodiversity is high. Many of these data are available only in unpublished...

Provedor de dados: 42
Autores: Avelino,Márcio F.; Vielliard,Jacques M.E.
The regional dialects or regiolects of the Rufous-collared Sparrow Zonotrichia capensis were compared between Campinas (47º06'W-22º90'S) and Botucatu (48º44'W-22º88'S), São Paulo State, Southeastern Brazil. Songs of 88 individuals from thirteen localities were recorded. Sonograms showed that two areas presented more homogeneous songs, forming two regiolects. In 11 localities most individuals shared the same song type. At the other two localities, they sang up to 5 different song types. This occurs at the boundaries of the regiolects, and was also where individuals singing more than one song type were found. Similarities between song types were not related to geographic distance between the respective singers. A comparative analysis showed similarities in...

Diversity and evolution of Amazonian birds: implications for conservation and biogeography
Provedor de dados: 42
Autores: RIBAS,CAMILA C.; ALEIXO,ALEXANDRE.
Abstract: Amazonia has been a focus of interest since the early days of biogeography as an intrinsically complex and extremely diverse region. This region comprises an intricate mosaic that includes diverse types of forest formations, flooded environments and open vegetation. Increased knowledge about the distribution of species in Amazonia has led to the recognition of complex biogeographic patterns. The confrontation of these biogeographic patterns with information on the geological and climatic history of the region has generated several hypotheses dedicated to explain the origin of the biological diversity. Genomic information, coupled with knowledge of Earth’s history, especially the evolution of the Amazonian landscape, presents fascinating...

Efficiency of playback for assessing the occurrence of five bird species in Brazilian Atlantic Forest fragments
Provedor de dados: 42
Autores: Boscolo,Danilo; Metzger,Jean Paul; Vielliard,Jacques M.E.
Playback of bird songs is a useful technique for species detection; however, this method is usually not standardized. We tested playback efficiency for five Atlantic Forest birds (White-browed Warbler Basileuterus leucoblepharus, Giant Antshrike Batara cinerea, Swallow-tailed Manakin Chiroxiphia caudata, Whiteshouldered Fire-eye Pyriglena leucoptera and Surucua Trogon Trogon surrucura) for different time of the day, season of the year and species abundance at the Morro Grande Forest Reserve (South-eastern Brazil) and at thirteen forest fragments in a nearby landscape. Vocalizations were broadcasted monthly at sunrise, noon and sunset, during one year. For B. leucoblepharus, C. caudata and T. surrucura, sunrise and noon were more efficient than sunset....

Species richness and relative abundance of birds in natural and anthropogenic fragments of Brazilian Atlantic forest
Provedor de dados: 42
Autores: Anjos,Luiz dos.
Bird communities were studied in two types of fragmented habitat of Atlantic forest in the State of Paraná, southern Brazil; one consisted of forest fragments that were created as a result of human activities (forest remnants), the other consisted of a set of naturally occurring forest fragments (forest patches). Using quantitative data obtained by the point counts method in 3 forest patches and 3 forest remnants during one year, species richness and relative abundance were compared in those habitats, considering species groups according to their general feeding habits. Insectivores, omnivores, and frugivores presented similar general tendencies in both habitats (decrease of species number with decreasing size and increasing isolation of forest fragment)....

Behavioural studies with cockatiels (Nymphicus hollandicus) in captivity are scarce. Due to the need for appropriate management of these animals, this study was performed to examine the behaviour of cockatiels kept in captivity at two temperatures. Sixteen cockatiels were individually housed in cages (62cm high x 43cm long x 27cm wide) and fed with a commercial ration and seed mixture for psittacids. Water was provided ad libitum. The eight-day experiment was divided into two stages of four days each. In the first stage, the birds were kept at room temperature (25°C) with 70% relative humidity during 24 hours. In the next stage, they were kept at 35°C from 06:00 to 18:00h and 25°C from 18:00 to 06:00h, also at 70% relative humidity. The behaviour of the...

Autores: Bueno,F.R.; Silva,C.A.; Oba,A.; Almeida,M.; Medeiros,L.G.; Pitarello,A.S.; Shinyashike,A.T.
ABSTRACT A total of 640 one-day-old Cobb broiler chicks, half male and half female, were reared up to 49 days of age. A completely randomized 2 × 4 factorial design was used. Experimental treatments consisted of four levels of organic zinc supplementation and one control (inorganic zinc supplementation) and two levels of sex (female and male), with four replicates of 16 birds per experimental plot. Animal performance, carcass and cut yields, and meat quality were evaluated. Feed intake increased with zinc supplementation. Broilers that received the lowest level of organic zinc showed better feed conversion than those fed an equivalent level of inorganic zinc. Increased levels of organic zinc reduced the abdominal fat content in females but impaired the...

O presente estudo apresenta o comportamento do gene HER2, a partir do uso da técnica de hibridização cromogênica in situ, em hiperplasias ductais atípicas associadas a carcinomas mamários caninos positivos para HER2. Aparentemente, uma fraca expressão da proteína HER2 foi observada nas hiperplasias ductais atípicas, bem como uma ausência de amplificação do seu gene codificador nessas hiperplasias e nos carcinomas mamários associados. O comportamento da proteína HER2 e do seu gene em carcinomas mamários caninos é similar ao observado em alguns subtipos histológicos de tumores mamários humanos, e a ausência dessas alterações sugerem que esse gene poderia aparentemente não estar envolvido com os estágios iniciais de proliferação celular atípica.

Salmonella Enteritidis and Salmonella Typhimurium are responsible for causing huge economic loses in aviculture, as they lead young broiler chicks to develop clinical disease and thus increase mortality. Salmonella's pathogenicity is considered complex and multifactorial, demanding more studies that could elucidate the interaction between host and pathogen. The present study aims to evaluate the virulence of 130S. Enteritidis isolates and 70S. Typhimurium inoculated in one-day-old chicks through the establishment of a pathogenicity index. For each strain, 10 commercial chicks from the Cobb lineage were used. Then, 200µL of a solution containing 2x108 CFU of S. Enteritidis or S. Typhimurium were inoculated in the birds by intraperitoneal via. Mortality and...

Are levels of digestive enzyme activity related to the natural diet in passerine birds?
Provedor de dados: 48
Autores: Ramírez-Otárola,Natalia; Sabat,Pablo.
Digestive capabilities, such as the rates nutrient hydrolysis and absorption, may affect energy intake and ultimately feeding behavior. In birds, a high diversity in gut biochemical capabilities seems to support the existence of a correlation between the morphology and physiology of the intestinal tract and chemical features of the natural diet. However, studies correlating the activity of digestive enzymes and the feeding habits at an evolutionary scale are scarce. We investigated the effect of dietary habits on the digestive physiological characteristics of eight species of passerine birds from Central Chile. The Order Passeriformes is a speciose group with a broad dietary spectrum that includes omnivorous, granivorous and insectivorous species. We...

Invasive exotic species can negatively impact local biodiversity. We present here a report of a nest predation of an endemic bird species, variable oriole (Icterus pyrrhopterus) by the introduced black-tufted marmoset (Callithrix penicillata) in an agricultural landscape highly disturbed by human activities. Two nestlings were predated, by adults of the introduced marmoset during two alternate days. Antipredator behavior and vocal mimicry were observed in variable oriole, while copulation was observed in black-tufted marmoset during the predation. The use of mobbing against predators by I. pyrrhopterus was observed and it is described here by the first time. The potential impact of the introduced marmosets to local biodiversity is discussed.

Bird-termite interactions in Brazil: A review with perspectives for future studies
Provedor de dados: 49
Autores: de Vasconcelos,Marcelo Ferreira; Hoffmann,Diego; de Araújo,Mércia Caroline; Vasconcelos,Prinscila Neves.
We present a review on the principal interactions between birds and termites in Brazil. We found 218 bird species feeding on termites or using termitaria for nesting or perching. Termites were mentioned as food source for 179 bird species. Alates were the most consumed caste. Termitaria were mentioned as nest site for 45 bird species. Some bird species also perch on the top of termite mounds to search for their prey or to conduct territorial and/or courtship displays. Considering all interactions between both animal groups, little is known about the identification of termite genera or species. Therefore, we suggest more detailed studies to be conducted on the natural history and ecology of interactions between birds and termites in Brazil.

Autores: Godoi,Maurício Neves; Costacurta,Marco de Barros; Nunes,Alessandro Pacheco; Patrial,Eduardo Weffort; Morante Filho,José Carlos.
The Crested Black-Tyrant (Knipolegus lophotes) is a member of the Tyrannidae family that occurs throughout open areas in central, southeastern and southern Brazil. Although this species occurs in regions that surround the state of Mato Grosso do Sul, there had never been a recorded sighting in the state. Thus, information on its distribution across Brazil's midwestern region is scarce. In this study, we report the first sightings of K. lophotes in Mato Grosso do Sul. These records extend the known distribution range of the species in midwestern Brazil and contribute to expanding knowledge of bird species composition in this region. We believe that the absence of K. lophotes from the lists of bird species recorded in different localities in Mato Grosso do...

Abstract Here we inferred about the effectiveness of a buffer zone composed by an Agroforestry System (AS) for providing reproductive conditions for Atlantic Forest birds by comparing artificial nest predation rates between a buffer zone, a primary forest area, and a set of small and isolated Atlantic Forest fragments. We have used 237 nests throughout the three areas, of which 100 (42.2%) were depredated. Predation frequencies were 28.6% in the continuous forest, 100% in the AS, and 51.9% in the fragments, differing significantly. We could detect nest predators in 48 of the 100 depredated nests (48%) using camera traps. Differences between areas may be attributed to changes in nest predator species. We support previous evidences that the conservation of...

Birds&amp;#8217; nests are elaborate constructions that are built to provide a safe and secure environment for the eggs and hatchlings of birds to develop. Twigs and leaves represent common nesting materials in birds&amp;#8217; nests globally and with their beaks, they can carry materials, sometimes larger than the birds themselves, to construct their nests. In addition to twigs and leaves, birds also use various other materials less frequently, such as bryophytes, and in this study we examined the prevalence of bryophytes in birds&amp;#8217; nests in Brazil. We analyzed the nest composition of 21 birds&amp;#8217; nests from the Brazilian bryophyte collection at the Institute of Botany (SP Herbarium) and found that bryophytes were a widely used nesting...

Autores: Mestre,Luiz Augusto Macedo; Krul,Ricardo; Moraes,Valéria dos Santos.
This study describes the mangrove bird community of Paranaguá Bay in Paraná - South Brazil. Seasonal surveys were conducted during September 1997 to September 1998 at three sites in Paranaguá Bay. Frequencies and abundances of birds were registered in 200m transects and one hour point counts. A total of 81 bird species were observed in the three sampling sites. Most of the bird species in Paranaguá mangroves are fruits, seeds and arthropods consumers, and predators of flying insects. The most frequent and abundant species were Egretta caerulea, Ceryle torquata, Chloroceryle amazona, Pitangus sulphuratus, Turdus amaurochalinus and Parula pitiayumi. The bird community of these three sites is composed mainly by forest bird species. The mangroves of Paranaguá...

Beauveria bassiana, an important insect pathogen was used to evaluate its effect on the feeding, behavior, histology of the digestory system and anatomy of Gallus domesticus. The fungus (strain Unioeste 4) was administrated orally treated with chicken food. Chicken feces were collected, and the birds observed for 28 days. Also, were evaluated the weight of the birds, as well as any sign of intoxication or pathological modification. Tissue samples were withdrawn to test lesions with the optic microscope. There was 100% of survival of the birds, and no behavior alteration or external lesion was found. The test group presented the highest weight gain (1383.9±54.4g). Viable conidia were observed in the feces until 24 h after feeding the fungus, indicating that...

Provedor de dados: 52
Autores: Landini,Gustavo Fraga; Di Vito Neto,Alfredo; Schwantes,Arno Rudi; Schwantes,Maria Luiza Barcellos; Santos,Marcelo dos.
Catharacta maccormicki blood samples were collected in the winter (October) and in the summer (February) in order to study the intraerythrocytic organic phosphates, hemoglobin (Hb) electrophoretic patterns, oxygen blood equilibrium and stripped Hbs, as well as the effect of 2,3-biphosphoglycerate (BPG) and inositol hexaphosphate (IHP) on oxygen affinity. All the samples (five from the winter and five from the summer) showed the same electrophoretic pattern: one minor fast component and one major slow one. No differences in oxygen affinity and Bohr effect in the samples collected in the winter and in the summer were found. Oxygen affinity was higher in the stripped Hb than in the blood. BPG seemed to have no effect on the functional properties of skua Hb...

Autores: Deef,Lamiaa Elsayed Mokhtar.
ABSTRACT  Quail is an important and interesting group of galliform birds. The Common quail (Coturnix coturnix); the Japanese quail (Coturnix japonica); the Panda quail (Coturnix japonica); the Dotted white quail (Coturnix japonica) and the Bobwhite quail (Colinus virginianus) were used in this study. PCR-RFLP and SDS-proteins were performed to reveal the genetic characterization and genetic relationship of the studied quails. Analysis of fragments generated by digestion of PCR product with restriction enzyme NlaIII recorded highly polymorphic restriction profiles. There is a wide intraspecific COI, SEMA3E and TLX genes variability among the studied quails. Protein bands varied from10 to 18 between quails with minimum number of bands were in the Dotted...

Microhabitat occupation by birds in a restinga fragment of Paraná coast, PR, Brazil
Provedor de dados: 52
Autores: Pedroso Junior,Nelson Novaes.
Studies were carried out to characterize microhabitat occupation by birds in a restinga fragment of Paraná coast. Were described 14 microhabitats occupied in different manners for 64 species of birds. Based on the results, could be suggested that this conspicuous class of vertebrates, together with the other elements that integrate the restinga, serve as a component to attract and stimulate the interest for the comprehension and necessity of conservation by the visitors of such ecosystem.

Provedor de dados: 52
Autores: Loures-Ribeiro,Alan; Anjos,Luiz dos.
An ecological analysis focused on distribution of Falconiformes, comprising abundance and morphology data, is provided. Samples were collected in a fragmented landscape within the Atlantic Rainforest, southern Brazil, between August and November 2001. Four main types of habitats were pinpointed among the 30 different sampling sites, while eight external morphological traits were employed. Twenty-one Falconiformes species were detected and jackknife estimates for regional richness reached 24.8 ± 2.56 species (p&lt;0.05). There were no differences between average number of diurnal birds of prey species in the different habitats under analysis (H-test, p&gt;0.05). Mantel's test for relative abundance and species morphology reveals weak association rates,...

Autores: Simões,Karina; Orsi,Antônio Marcos; Artoni,Silvana Martinez Baraldi; Cruz,Claudinei da; Schimming,Bruno César; Pinheiro,Patrícia Fernanda Felipe.
The epididymal region of the domestic duck is composed by efferent ductules, whose histotopology was characterized by the proximal and distal ductules and sequentially by the epididymal duct. The epithelial lining of the efferent ductules was ciliated pseudostratified and formed by columnar cells. Also the ducts epididymidis epithelium was pseudostratified but non-ciliated. Concerning the histomorphometric analysis, the epithelial height mean was significantly greater in the distal efferent ductules, differing from the lower epithelium height mean observed in proximal efferent ductules and epididymal duct. The maximum and minimum diameter mean were significantly greater in the proximal efferent ductules, comparatively to the same diameter means of the...

Is the relationship between population density and body size consistent across independent studies? A meta-analytical approach
Provedor de dados: 57
Autores: BINI,L. M.; COELHO,A. S. G; DINIZ-FILHO,J. A. F.
The Energetic Equivalence Rule (EER) is a controversial issue in ecology. This rule states that the amount of energy that each species uses per unit of area is independent of its body size. Here, we perform a meta-analytical procedure to combine and compare the slopes of population density and body size relationships across independent studies of mammals and birds. We then compared a distribution of 50,000 bootstrap combined slopes with the expected slope (b = -0.75) under the EER. The combined slopes obtained for mammals and birds separately were -0.755 and -0.321, respectively. The homogeneity hypothesis (i. e. within studies the slopes differ by no more than would be expected due sampling variation) was rejected in both cases. So, EER cannot be...

Diurnal bird visiting of Caryocar brasiliense Camb. in Central Brazil
Provedor de dados: 57
Autores: MELO,C.
Nectar of nocturnal flowers may be used by diurnal species that occasionally accomplish secondary pollination. Thirteen bird species visited Caryocar brasiliense flowers in central Brazil. There is a temporal separation between nectarivores and non-nectarivores species. Nectarivores birds visited flowers late in the morning, while other species appear earlier. C. brasiliense nectar may be an alternative resource to birds visitors during the dry season.

ABSTRACT:  Considering that neem (Azadirachta indica A. Juss.) causes deleterious effects on fertility, the objective was to evaluate the effect of feeding quail (Coturnix coturnix japonica Linnaeus, 1758) of 90 days old with neem seeds on seminal quality, biometric parameters, and testicular morphometrics, as an experimental model. After the 30 day adaptation period to the experimental conditions, birds were randomly distributed in five treatments of neem seeds incorporated into feed, with 10 replicates: T1 (0%), T2 (5%), T3 (10%), T4 (20%) and T5 (40%). After 60 days of receiving experimental rations, their semen was collected to evaluate the sperm quality, the birds were euthanized, and testes were submitted to biometric, histological, and...

Occurrence of Amblyomma longirostre in Cyanocompsa brissonii in Rio Grande do Sul, Brazil
Provedor de dados: 65
Autores: Gressler,Lucas Trevisan; Pereira,Larissa Quinto; Brustolin,Joice Magali; Lovato,Maristela; Monteiro,Sílvia Gonzalez.
ABSTRACT: Ticks are arthropods that are highly competent in transmitting pathogens to animals and humans. Among these, the genus Amblyomma is the most representative within the Neotropics. Amblyomma longirostre ticks are naturally distributed in countries of South, Central and North America. Their immature stages preferentially parasitize birds (Passeriformes), while adult stages are usually found on rodents. Therefore, reports of this tick species on wild hosts is epidemiologically relevant, especially because of these ticks' potential for transmitting pathogens to other wild and domestic animals, and also to humans. Thus, the aim of this study was to report infestation by Amblyomma longirostre on Cyanocompsa brissonii in southern Brazil.
