Accurately quantifying species' area requirements is a prerequisite for effective area-based conservation. This typically involves collecting tracking data on species of interest and then conducting home range analyses. Problematically, autocorrelation in tracking data can result in space needs being severely underestimated. Based on the previous work, we hypothesized the magnitude of underestimation varies with body mass, a relationship that could have serious conservation implications. To evaluate this hypothesis for terrestrial mammals, we estimated home-range areas with global positioning system (GPS) locations from 757 individuals across 61 globally distributed mammalian species with body masses ranging from 0.4 to 4000 kg. We then applied blockcross...

Extinctions of interactions: quantifying a dung beetle-mammal network.
Provedor de dados: Acesso Livre à Informação Científica da Embrapa (Repositório Alice)
Autores: RAINE, E. H.; MIKICH, S. B.; LEWIS, O. T.; RIORDAN, P.; VAZ-DE-MELLO, F. Z.; SLADE, E. M.
Loss of large-bodied mammals across the globe through hunting, habitat degradation, and fragmentation is one of the most significant anthropogenic impacts on the environment. Cascading effects of these extinctions through ecosystems have been little studied, although correlative studies have revealed co-extinctions in closely linked groups, with implications for ecosystem structure and function. Despite playing important roles in seed dispersal and hence seedling recruitment, mammals have been largely neglected in network studies. Similarly, the role of secondary seed dispersers, such as ants and dung beetles, has been largely unexplored. Most dung beetles rely on mammal feces for feeding and breeding and provide a suite of important ecosystem functions...

Background: Integration of high throughput DNA genotyping and RNA-sequencing data allows for the identification of genomic regions that control gene expression, known as expression quantitative trait loci (eQTL), on a whole genome scale. Intramuscular fat (IMF) content and carcass composition play important roles in metabolic and physiological processes in mammals because they influence insulin sensitivity and consequently prevalence of metabolic diseases such as obesity and type 2 diabetes. However, limited information is available on the genetic variants and mechanisms associated with IMF deposition in mammals. Thus, our hypothesis was that eQTL analyses could identify putative regulatory regions and transcription factors (TFs) associated with...

ABSTRACT This is the first study to investigate mercury (Hg) contamination in felid species in the Brazilian Amazon. We collected 26 fur samples from wild felids of four species (Puma concolor, Panthera onca, Leopardus pardalis and Leopardus wiedii) occurring in the Mamirauá and Amanã sustainable development reserves, in the state of Amazonas. Samples were from museum specimens, except for five P. onca samples collected from free-living individuals. Total Hg concentrations ranged from 0.12 to 48.1 µg g-1. Concentrations of Hg did not differ significantly between museum specimens and live individuals of P. onca, but varied significantly among species, with significantly higher concentrations for P. onca and L. pardalis, which could be related to factors...

Flower and fruit development of Parkia pendula (Fabaceae, Mimosoideae)
Provedor de dados: Acta Botanica Brasilica
Autores: Piechowski,Daniel; Gottsberger,Gerhard.
Parkia pendula occurs in Brazil in Amazonia and in the northeastern Atlantic Forest. In the latter, its buds, nectar, and seedpod gum are discussed to be keystone resources for the mammalian fauna. To enhance the knowledge about these important nourishment sources, the aim of this study was to detect and describe distinct phases in the flower and pod development. The study was conducted in a 306 ha forest fragment in Igarassu, Pernambuco, northeastern Brazil. Six morphometrical variables were measured weekly at five inflorescences of two individuals from September 2003 to January 2004. Eleven distinct developmental phases were identified in the 21 weeks lasting development from the very first inflorescences to mature pods and are described in detail. These...

Stratigraphic framework of early Pliocene fossil localities along the north bank of the Cimarron River, Meade County, Kansas
Provedor de dados: Ameghiniana
Autores: Honey,James G.; Peláez-Campomanes,Pablo; Martin,Robert A.
The stratigraphy of early Pliocene (early Blancan) fossiliferous sediments exposed in canyons along the north bank of the Cimarron River in Meade County, Kansas is described as part of a larger, ongoing project to create a refined biostratigraphic model for late Neogene and Pleistocene mammalian fossil localities from the Meade Basin. Because the utility of previously named formation and member names is questionable, we introduce a set of informal names for stratigraphic units in our study area. Sediments in the region are up to 34 m thick, and include a basal sand and gravel ("Bishop gravel") at least 9 m thick, overlain by up to 17 m of lightto pinkish-gray, fine-grained sand and silt, with interbedded calcium carbonate layers. These fine-grained...

Didelphidae marsupials (Mammalia, Didelphimorphia) from the Late Pleistocene deposit of the Gruta dos Moura Cave, northern Brazil
Provedor de dados: Anais da Academia Brasileira de Ciências
Autores: Nova,Patricia Villa; Avilla,Leonardo S.; Oliveira,Édison V.
The present study acknowledges the diversity of fossil marsupials from the Gruta dos Moura cave, as well as environmental and climatic aspects during the Quaternary. The results show that this is the largest diversity of Pleistocene marsupials recorded in a single cave: Didelphis albiventris, D. aurita, Gracilinanus agilis, G. microtarsus, Marmosa murina, Monodelphis brevicaudata, M. domesticaand Sairadelphys tocantinensis. Furthermore, the described specimens are also part of the only fossil assemblage unequivocally referable to the late Pleistocene. Paleontological studies suggest an intimate association with dry and open environments with high abundance of water sources. Since most of the identified taxa are characteristic of open forests and gallery...

The Dasypodidae (Mammalia, Xenarthra) from the Urso Fóssil Cave (Quaternary), Parque Nacional de Ubajara, State of Ceará, Brazil: paleoecological and taxonomic aspects
Provedor de dados: Anais da Academia Brasileira de Ciências
Autores: OLIVEIRA,PAULO V.; RIBEIRO,ANA MARIA; OLIVEIRA,ÉDISON V.; VIANA,MARIA SOMÁLIA S.
This paper deals with xenarthrans osteoderms assigned toDasypus aff. D. novemcinctus,Euphractus sexcinctus and Cabassous sp. The material was collected in subsurface, from 0.10 to 0.60 m in the Urso Fóssil Cave, Parque Nacional de Ubajara, State of Ceará, northeastern Brazil. The ages of sediment samples from levels 4 and 5 (depths of 0.40 and 0.50 m) were determined by thermoluminescence technique, and indicated ages of 8,000 and 8,200 years BP for each layer respectively. The presence in these layers of early Holocene xenarthrans taxa can contribute to the understanding of the biotic evolution of the northwest region of Ceará during the last 10,000 years. Two of the three identified taxa still occur in the region: Dasypus novemcinctus andEuphractus...

A memory like a female Fur Seal: long-lasting recognition of pup's voice by mothers
Provedor de dados: Anais da Academia Brasileira de Ciências
Autores: Mathevon,Nicolas; Charrier,Isabelle; Aubin,Thierry.
In colonial mammals like fur seals, mutual vocal recognition between mothers and their pup is of primary importance for breeding success. Females alternate feeding sea-trips with suckling periods on land, and when coming back from the ocean, they have to vocally find their offspring among numerous similar-looking pups. Young fur seals emit a 'mother-attraction call' that presents individual characteristics. In this paper, we review the perceptual process of pup's call recognition by Subantarctic Fur Seal Arctocephalus tropicalis mothers. To identify their progeny, females rely on the frequency modulation pattern and spectral features of this call. As the acoustic characteristics of a pup's call change throughout the lactation period due to the growing...

Effects of reduced-impact logging on medium and large-bodied forest vertebrates in eastern Amazonia
Provedor de dados: Biota Neotropica
Autores: Laufer,Juliana; Michalski,Fernanda; Peres,Carlos A.
Standard line-transect census techniques were deployed to generate a checklist and quantify the abundance of medium and large-bodied vertebrate species in forest areas of eastern Amazonia with and without a history of reduced-impact logging (RIL). Three areas were allocated a total of 1,196.9 km of line-transect census effort. Sampling was conducted from April to June 2012 and from April to August 2013, and detected 29 forest vertebrate species considered in this study belonging to 15 orders, 20 families and 28 genera. Additionally, eight species were recorded outside census walks through direct and indirect observations. Of this total, six species are considered vulnerable according to IUCN (Ateles paniscus, Myrmecophaga tridactyla, Priodontes maximus,...

Autores: Tonini,João Filipe Riva; Carão,Lívia de Moraes; Pinto,Israel deSouza; Gasparini,João Luiz; Leite,Yuri Luiz Reis; Costa,Leonora Pires.
Reserva Biológica de Duas Bocas (2,910 ha) is one of the largest Atlantic forest remnants in the State of Espírito Santo, Southeastern Brazil. We recorded non-volant tetrapods in this area from May 2007 through April 2008, using pitfalls, live traps, camera traps, and diurnal and nocturnal opportunistic searches. In addition, we compiled available museum and literature records from this area. We documented 52 species of amphibians, 24 species of non-avian reptiles, and 39 species of non-volant mammals. Out of these 115 species, 47 are new records for this area and six other species had their geographic ranges expanded with the present study. Furthermore, we present the record of predation of the tree frog Hypsiboas faber by the snake Chironius bicarinatus....

Abstract The Restinga forests are plant formations associated to the Atlantic Forest which still have not been much studied in terms of their mastofauna. The objective of the present work was to list for the first time the mammal species found in a Restinga on northeastern Brazil and show the similarities on species composition to other areas of the same environment and of Atlantic Forest. Our records were based on several complementary approaches: field survey, interviews, and museum collections. Subsequently, we performed similarity analysis between Restinga areas along Brazil and Atlantic Forest areas. We found a total of 30 species of mammals distributed in 28 genera, 16 families and 7 orders for Restinga of Mataraca. Species richness was similar to...

The role of gallery forests in the distribution of cerrado mammals
Provedor de dados: Brazilian Journal of Biology
Autores: JOHNSON,M. A.; SARAIVA,P. M.; COELHO,D.
The Cerrado biome contains a rich mammal community, with an influence from the Amazonian and Atlantic rainforests, principally observed in the gallery forests. In this paper, through literature review, it is shown that the non-volant mammal community of the gallery forests is distinct from the mammal communities of any other physionomy of the Cerrado. Additionally, the gallery forests contain twice as many species common to the rainforests when compared to all the other physiognomies of the Cerrado combined. The gallery forests appear to provide habitat within the Cerrado for rainforest mammals, increasing the biodiversity of this biome. As such, gallery forests may function as dispersion corridors for these species.

Is the relationship between population density and body size consistent across independent studies? A meta-analytical approach
Provedor de dados: Brazilian Journal of Biology
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...

Identification of animals that are decomposing or have been run over or burnt and cannot be visually identified is a problem in the surveillance and control of infectious diseases. Many of these animals are wild and represent a valuable source of information for epidemiologic research as they may be carriers of an infectious agent. This article discusses the results obtained using a method for identifying mammals genetically by sequencing their mitochondrial DNA control region. Fourteen species were analyzed and identified. These included the main reservoirs and transmitters of rabies virus, namely, canids, chiroptera and primates. The results prove that this method of genetic identification is both efficient and simple and that it can be used in the...

Erythrocyte membrane proteins from 44 representative mammals were studied. Protein 4.2 was not detected in guinea pigs (Cavia porcellus) (N = 14), Southern Brazilian swamp large rats (Myocastor coypus) (N = 2), cutias (Dasyprocta sp) (N = 4), and horses (Equus caballus) (N = 13). These animals also presented high ankyrin concentrations except for the horse which did not exhibit a sharp band, although minor components located between proteins 2 and 3 could account for the ankyrin family. The rodents studied did present band 6, which was not detectable in other common rodents such as white rats (Rattus norvegicus) (N = 9) and mice (Mus musculus) (N = 12). Since the absence of protein 4.2 does not disrupt the cytoskeleton membrane, we suggest that it is not...

Estrogens and male reproduction: a new concept
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Carreau,S.; Silandre,D.; Bourguiba,S.; Hamden,K.; Said,L.; Lambard,S.; Galeraud-Denis,I.; Delalande,C.
The mammalian testis serves two main functions: production of spermatozoa and synthesis of steroids; among them estrogens are the end products obtained from the irreversible transformation of androgens by a microsomal enzymatic complex named aromatase. The aromatase is encoded by a single gene (cyp19) in humans which contains 18 exons, 9 of them being translated. In rats, the aromatase activity is mainly located in Sertoli cells of immature rats and then in Leydig cells of adult rats. We have demonstrated that germ cells represent an important source of estrogens: the amount of P450arom transcript is 3-fold higher in pachytene spermatocytes compared to gonocytes or round spermatids; conversely, aromatase activity is more intense in haploid cells. Male germ...

The role of game mammals as bushmeat In the Caatinga, northeast Brazil
Provedor de dados: Ecology and Society
Although the use of wild mammals as a source of food has been better studied in tropical forest environments, their importance as a source of protein for human communities in semiarid environments is little known. In the latter, the availability of wild animal meat is limited in comparison to other environments. In the semiarid regions of northeastern Brazil, hunting wild mammals for their meat is traditional, playing a crucial role in the livelihoods and food security of various rural and urban communities, especially during the annual drought seasons. In this study, we investigated the role of wild mammals as bushmeat in 10 communities within the Caatinga biome in northeast Brazil. We used key-informant interviews, household surveys, and questionnaires...

Mammalian Herbivores in the Boreal Forests: Their Numerical Fluctuations and Use by Man
Provedor de dados: Ecology and Society

Within the boreal zone, there are about 50 native mammalian herbivore species that belong to the orders Artiodactyla, Rodentia, and Lagomorpha. Of these species, 31 occur in the Nearctic and 24  in the Palaearctic. Only six species occur in both regions. Species of the family Cervidae have probably been, and still are, the most important group for man, as they provide both meat and hides. Pelts from squirrels, muskrats, and hares were commercially harvested at the beginning of the century, but have less value today. The semi-domestic reindeer in the Palaearctic produces meat and hides on a commercial basis. It is also used for milking, to a limited extent, as is the semi-domestic moose in Russia. The Siberian musk deer is used for its musk and is raised in...

Scaling of Natal Dispersal Distances in Terrestrial Birds and Mammals
Provedor de dados: Ecology and Society

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....

Extinction of mammalian populations in conservation units of the Brazilian Cerrado by inbreeding depression in stochastic environments
Provedor de dados: Genetics and Molecular Biology
Autores: Silva,Marcel Müller Fernandes Pereira da; Diniz-Filho,José Alexandre Felizola.
Despite methodological and theoretical advances in conservation genetics, data on genetic variation on broad regional spatial scales are still scarce, leading conservation planners to use general heuristic or simulation models for an integrated analysis of genetic, demographic and landscape parameters. Here, we extended previous results by evaluating spatial patterns of extinction by inbreeding depression under stochastic variation of environments for mammalian populations in 31 conservation units of the Brazilian Cerrado. We observed a large spatial variation of times to extinction, for different conservation units and body-size classes of species. For small-bodied species (500 g), the population times to extinction in the conservation units were usually...

Molecular evidence for a recent demographic expansion in the puma (Puma concolor) (Mammalia, Felidae)
Provedor de dados: Genetics and Molecular Biology
Autores: Matte,Eunice M.; Castilho,Camila S.; Miotto,Renata A.; Sana,Denis A.; Johnson,Warren E.; O'Brien,Stephen J.; Freitas,Thales R. O. de; Eizirik,Eduardo.
The puma is an iconic predator that ranges throughout the Americas, occupying diverse habitats. Previous phylogeographic analyses have revealed that it exhibits moderate levels of genetic structure across its range, with few of the classically recognized subspecies being supported as distinct demographic units. Moreover, most of the species' molecular diversity was found to be in South America. To further investigate the phylogeographic structure and demographic history of pumas we analyzed mtDNA sequences from 186 individuals sampled throughout their range, with emphasis on South America. Our objectives were to refine the phylogeographic assessment within South America and to investigate the demographic history of pumas using a coalescent approach. Our...

Genetic variability of Herpailurus yagouaroundi, Puma concolor and Panthera onca (Mammalia, Felidae) studied using Felis catus microsatellites
Provedor de dados: Genetics and Molecular Biology
Autores: Moreno,Vanessa Roma; Grisolia,Alexéia Barufatti; Campagnari,Francine; Milazzotto,Marcela; Adania,Cristina Harumi; Garcia,José Fernando; Souza,Edislane Barreiros de.
We used four microsatellite loci (Fca08, Fca45, Fca77 and Fca96) from the domestic cat, Felis catus, to investigate genetic variability in specimens of Herpailurus yagouaroundi (jaguarundi, otter cat, eyra), Puma concolor (cougar, mountain lion, puma) and Panthera onca (jaguar) held in various Brazilian zoos. Samples of DNA from the cats were PCR amplified and then sequenced before being analyzed using the CERVUS program. Our results show a mean polymorphic information content (PIC) of 0.83 for H. yagouaroundi, 0.66 for P. concolor and 0.69 for P. onca and a mean of 10.3 alleles for the Fca08 locus, 5.3 for Fca 45, 9 for Fca 77 and 14 for Fca 96. These results indicate a relatively high level of genetic diversity for the specimens studied.

Susceptibility of targets to the vampire bat Desmodus rotundus are proportional to their abundance in Atlantic Forest fragments?
Provedor de dados: Iheringia Série Zoologia
Autores: Zortéa,Marlon; Silva,Diego A.; Calaça,Analice M.
ABSTRACT Desmodus rotundus (É. Geoffroy, 1810) feeds preferably on mammal blood, including livestock animals, such as bovine cattle. In spite of using native preys in the wild, records of this feeding activity are scarce. In the present study, we investigated the foraging activity of D. rotundus based on video footage from camera traps in Atlantic Forest fragments in southern Goiás State, Brazil. Out of 23 mammal species recorded in the study area, four had interactions with Desmodus rotundus (Priodontes maximus, Tapirus terrestris, Mazama americana and Pecari tajacu). The records were obtained from early night to sunrise. There was a correlation between abundance of potential preys and the choice of the target by D. rotundus. Most of the bat-prey...

Mammal inventories in Seasonal Neotropical Forests: traditional approaches still compensate drawbacks of modern technologies
Provedor de dados: Iheringia Série Zoologia
Autores: Carvalho,William D.; Rosalino,Luís M.; Adania,Cristina H.; Esbérard,Carlos E. L.
ABSTRACT Variation in body size, behavior, feeding habits and habitat use patterns in medium- and large-sized mammals influence the adequacy of sampling methods to register presence and abundance. Moreover, even if methods are similarly adequate, different methodologies result in distinct cost-efficiency relationships (i.e. some may have reduced costs, be less time-consuming and/or require less-skilled technicians). Focusing on three different sampling methods commonly used to monitor medium and large mammals in seasonal tropical forests, we compared the species richness detected by each method and quantified their cost-efficiencies: (1) camera traps; (2) line transects for direct observations of animals; and (3) line transects seeking tracks/footprints....

O monitoramento de mamíferos em fazendas é relevante tanto para a conservação da biodiversidade quanto para a geração de ações de sustentabilidade em áreas de fruticultura. Por exemplo, mamíferos carnívoros predando roedores, podem atuar no controle de pragas agrícolas. Por isso determinar quais espécies são encontradas em fazendas e em áreas de vegetação natural permite identificar as espécies e caracterizar as comunidades. Atualmente, estamos enfrentando uma crise ambiental em precedentes, a sexta extinção em massa da biodiversidade. Estima-se que a perda de espécies em um curto período de tempo equivale a processos de extinção ocorridos há milhões de anos, onde se propõe um novo período geológico: o Antropoceno, a era da humanidade.

Autores: Leclerc, Camille; Villéger, Sébastien; Marino, Clara; Bellard, Céline; Di Minin, Enrico.
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...

Autores: Estecondo,Silvia; Codón,Stella Maris; Casanave,Emma Beatriz.
The histology of the salivary glands of the armadillo Zaedyus pichiy (Desmarest, 1804) was studied. Three pairs of major compound tubuloacinar salivary glands, parotid, submandibular and sublingual, were distinguished. The parotid gland is histologically a serous gland. The submandibular gland consists of two lobes. The anterior lobe is composed of mixed and serous acini. The posterior lobe is predominantly mucous. There is a reservoir or salivary bladder, related with the anterior lobe. The sublingual gland is mixed, composed of mucous acini with scattered serous demilunes

The histology of the salivary glands of the armadillo Dasypus hybridus (Desmarest, 1804), was studied. Two pairs of salivary glands, parotid and submaxillary, and a salivary bladder are distinguished. Parotids are located anteriorly to the submaxillary glands. They are purely serous glands and excretory intralobular ducts, intercalated and particularly striated ones, are very numerous. Submaxillary glands are of greater size. They possess two lobes, which differs in their histology and histochemistry. The anterior lobe is mixed and the presence of numerous intralobular excretory ducts is remarkable. The bigger posterior lobe is mucous. Intralobular excretory ducts are observed, but they are not as abundant as in the anterior portion

Autores: Möller,Richard; Vazquez,Noelia; Teliz,Diana; Méndez,Virginia.
The laboratory rat (Rattus norvegicus albinus) has been used as a model for medical, biological and molecular research, for a long time. It is an interesting fact that there are no detailed descriptions of the gross anatomy of the liver and its ways of fixation. The aim of this study is to define clearly and according to the Nomina Anatomica Veterinaria principles, the liver and its way of fixation in this species of laboratory mammal. Eighty-eight rats (Rattus norvegicus albinus) were used, with a weight between 250 and 450 g. They were dissected in fresh, after been euthanized by an overdose of thiopental sodium intraperitoneal. An incision from the xiphoid cartilage up to the pubic region was made and another on each costal arch toward dorsal.

An updated analysis of the distribution of cites-listed peruvian carnivores for conservation priorities
Provedor de dados: Mastozoología Neotropical
Autores: Hurtado,Cindy M; Pacheco,Víctor; Fajardo,Úrsula; Uturunco,Angie.
Species in the Order Carnivora are susceptible to habitat fragmentation, deforestation, and climate change because of their medium to large size, large spatial requirements, and other species-specific require­ments, providing challenges to conservation and management. Understanding their distributions and occurrence in the face of these threats is crucial for conservation. Peru has 21 carnivore species regulated by the CITES Convention (61.8% of all Peruvian carnivore species). The aims of this project were: a) to generate distribution maps of Peruvian carnivores listed by CITES, b) to describe their distribution by ecoregions, c) to describe changes in species richness through time, and d) to identify species and areas in need of further research and...

State of Biodiversity: Western Cape Province, South Africa Mammals
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Lloyd, P.H.
The Western Cape Province (W.C.P.) of South Africa, one of nine provinces forming the country, is generally regarded in South African terms as being “poor” with respect to the number of its mammals when compared to the other eight provinces. This misconception has its origin in the fact that the Western Cape, essentially a winter rainfall region, lies adjacent to one of the richest spots in the world in terms of mammalian diversity, namely the summer rainfall region of the rest of South Africa. In fact only when compared with the rest of our own country can the Western Cape be regarded as having a “poor” mammofauna in terms of biodiversity. However, some of the other Western Cape vertebrate and many of the invertebrate groups do reflect higher levels of...

Autores: MEDINA,CÉSAR E.; PINO,KATERYN; PARI,ALEXANDER; LLERENA,GABRIEL; ZEBALLOS,HORACIO; LÓPEZ,EVARISTO.
ABSTRACT Bahuaja Sonene National Park protects the unique sample of subtropical humid savannas in Peru, which are known as “Pampas del Heath” with 6,136 hectares of area. Many endangered species and/or endemic from savannas occur there, however studies about the diversity of mammals in Pampas del Heath are limited and only three assessments there have been carried out since mid-1970s. Therefore we surveyed mammals in three habitat types of the Pampas del Heath (savanna, ecotonal area and forest) during late 2011. We used several methods of record for the different mammal groups including 1) capture techniques with mist nets, snap traps, Sherman traps, Tomahawk traps and pitfall traps, 2) and detection techniques direct by means of camera traps,...

The Araucaria Forest (AF) once covered 37% of State of Parana, but nowadays less than 1% of mature AF was left. Besides being one of the most threatened Brazilian ecosystems, the AF is also poorly studied. So, the main objective of the present study was to contribute with the knowledge and conservation of Parana state mammals, focusing on AF species. The field study was conducted in the Embrapa Florestas property (25º19’ S – 49º09’ W), that has 301 ha of which 105 ha are covered by disturbed primary AF and the other 196 ha by secondary AF forests and forest plantations. Mammalian records were made twice a week between April 2003 and February 2004 employing direct and indirect methods including visual observations, analysis of vestiges, collection of dead,...

Comparing the effectiveness of tracking methods for medium to large-sized mammals of Pantanal
Provedor de dados: Revista Brasileira de Zoologia
Autores: Olifiers,Natalie; Loretto,Diogo; Rademaker,Vitor; Cerqueira,Rui.
Most Neotropical mammals are not easily observed in their habitats, and few studies have been conducted to compare the performance of methods designed to register their tracks. We compared the effectiveness of track registry between sand plots and two tracking methods that use artificial materials to record tracks: the sooted paper, and the plastic board methods. The latter is described here for the first time. From 2002 to 2005, we conducted two experiments in three study sites in the Pantanal region of Brazil. We compared the artificial methods with the sand plot by registering track presence/absence, the number of identifiable tracks, and the total number of tracks (identifiable and unrecognizable) in each tracking plot. Individuals avoided artificial...

Construction of arboreal nests by brown-nosed coatis, Nasua nasua (Carnivora: Procyonidae) in the Brazilian Pantanal
Provedor de dados: Revista Brasileira de Zoologia
Autores: Olifiers,Natalie; Bianchi,Rita de C.; Mourão,Guilherme de M.; Gompper,Matthew E.
The construction of arboreal nests is rare among mammals in the order Carnivora. However, coatis (Procyonidae: Nasua Storr, 1780) build arboreal nests that are used for resting or birthing. Here we describe Nasua nasua (Linnaeus, 1766) nests located during a telemetry study of coatis in the Brazilian Pantanal. Coati nests were all "bird-like", that is, open nests having a semispherical shape. Nests were constructed of twigs, branches, and lianas sometimes interlaced with leaves. Nest volume was 30-50 cm³ and average nest height was approximately 9.5 m. Nests were found in open "cerrado" vegetation, along forest edges, or in interior "cordilheiras" forest. The reasons why coatis build such nests are unclear, but may relate to inter or intraspecific...

Mamíferos descritos do estado de Santa Catarina, Brasil
Provedor de dados: Zoologia
Autores: Avila-Pires,Fernando Dias de.
Sixteen species of mammals have been described from the State of Santa Catarina, Brazil. The region is poorly represented in mammal collections, and many of these species have been synonimized on the basis of geographical proximity, without a serious consideration of their validity. The sixteen species plus one described from Paraná with a paratype from Santa Catarina are listed, with pertinent information on their type localities, correct bibliographical reference, and present status. Type localities are spelled exactly as they appear in the original descriptions.

Roadkills of vertebrates in Venezuela
Provedor de dados: Zoologia
Autores: Pinowski,Jan.
This paper presents an analysis of vertebrate roadkills in five different habitats of tropical South America. Observations of vertebrate roadkills were conducted in 1978, on a 572 km road between Caracas and Mantecal/Apure in Venezuela, during the rainy season (June-October). During five passages on this route, which includes five distinct habitats, 79 vertebrate carcasses - mammals and reptiles - were found. If we assume that the carcasses remain for two days on the road, vehicles can be expected to strike 350 spectacled caimans Caiman crocodilus Linnaeus, 1758 (Alligatoridae) during the rainy season alone. Similar calculations for other species yield 313 snakes and lizards, 294 opossums Didelphis marsupialis Linnaeus, 1758 (Didelphidae), 220 crab-eating...

Provedor de dados: Zoologia
Autores: Aguiar,Ludmilla M. S.; Antonini,Yasmine.
We examined food habits of Vespertilionidae bats Myotis nigricans (Schinz, 1821) and Eptesicus furinalis (d'Orbigny, 1847) by fecal analysis in cerrado sensu stricto and gallery forests, within APA - Gama-Cabeça-de-Veado, Brasília, Distrito Federal, Brazil. Out of 20 fecal samples collected, seven were of Eptesicus furinalis and 13 of Myotis nigricans. The diet of E. furinalis included six orders of insects: Coleoptera (5/7 by items presence), Lepidoptera and Hymenoptera (3/7), Diptera, Hemiptera and Homoptera (1/7). The diet of M. nigricans included all the main orders consumed by E. furinalis (6/13, 4/13, 4/13, 3/13, 1/13, and 4/13 respectively) and one other order: Orthoptera (1/13). Homoptera, Diptera and Orthoptera were collected only in bats captured...

Autores: Avila-Pires,Fernando Dias de.
The contribution of the Franciscan priest Francisco dos Prazeres to our knowledge of the natural history, geography, history and ethnography of Maranhão in the early XIXth Century appeared in the Revista do Instituto Histórico e Geographico do Brazil in 1891. The original manuscript was donated to the Instituto's library in 1843, and disapeared. The printed text was a copy, without the orignal map, donated by Colonel Francisco Manoel da Cunha Júnior. Fray Francisco was a corresponding member, and a better historian and geographer than a zoologist. This paper summarizes the available information on the zoological expeditions that explored Maranhão. A list of all mammals described in the Poranduba Maranhense is provided, followed by the identification of the...

Rock paintings of mammals at Central, Bahia, Brazil
Provedor de dados: Zoologia
Autores: Beltrão,Maria da Conceição de M.C.; Locks,Martha.
Rock paintings of mammals have been studied in five of the 243 localities contained within the 270,000 km² Archeological Region of Central, Bahia. From features of external morphology, it was possible to recognize 11 mammals represented in the paintings: for five, to attribute the species; another five, the genera; and, for one, merely the family. This study aims to underline the importance of prehistoric man's contribution, by way of these rock paintings, to our knowledge of the mammals depicted, both taxonomically and in terms of their distribution within the bounds of the Project in the State of Bahia.
