Using Ants as bioindicators:  Multiscale Issues in Ant Community Ecology
Provedor de dados: Ecology and Society
Autores: Andersen, Alan; Wildlife and Ecology, CSIRO Tropical Ecosystems Research Centre; Alan.Andersen@terc.csiro.au.
Ecological patterns and processes are characteristically scale dependent, and research   findings often cannot be translated easily from one scale to another. Conservation biology is challenged by a lack of congruence between the spatial scales of ecological research (typically involving small plots) and land management (typically involving whole landscapes). Here, I discuss spatial scaling issues as they relate to an understanding of ant communities and, consequently, their use as bioindicators in land management. Our perceptions of fundamental patterns and processes in ant communities depend on scale: taxa that are behaviorally dominant at one scale are not necessarily so at others, functional groups recognized at one scale are often inappropriate for...

In the interests of improving engagement with Pacific Island communities to enable development of effective and sustainable adaptation strategies to climate change, we looked at how traditional oral narratives in rural/peripheral Fiji communities might be used to inform such strategies.  Interviews were undertaken and observations made in 27 communities; because the custodians of traditional knowledge were targeted, most interviewees were 70-79 years old.  The view that oral traditions, particularly those referring to environmental history and the observations/precursors of environmental change, were endangered was widespread and regretted.  Interviewees&amp;#8217; personal experiences of extreme events (natural disasters) were commonplace but no...

Composition and ecological patterns of snake assemblages in an Amazon-Cerrado Transition Zone in Brazil
Provedor de dados: Iheringia Série Zoologia
Autores: Pinheiro,Leandra C.; Abe,Pedro S.; Bitar,Youszef O. C.; Albarelli,Luiz P. P.; Santos-Costa,Maria C.
ABSTRACT The present study encompasses the species composition and ecological characteristics of the snake community in a Cerrado-Amazon transition zone in Midwest of Brazil (state of Mato Grosso). The data were collected during six excursions to the "Tanguro" (study area) by visual encounter survey, pitfall traps with drift fences and non-systematic sampling. We collected 194 specimens, distributed in 34 species, 26 genera, and eight families. The most abundant species were Crotalus durissus Linnaeus, 1758 (n = 50), Philodryas olfersii (Lichtenstein, 1823) (n = 15), Philodryas nattereri Steindachner, 1870 (n = 13), Xenodon rabdocephalus (Wied, 1824) (n = 12), Lachesis muta (Linnaeus, 1766) (n = 10) and Erythrolamprus almadensis (Wagler, 1824) (n = 10)....

Reproductive modes and fecundity of an assemblage of anuran amphibians in the Atlantic rainforest, Brazil
Provedor de dados: Iheringia Série Zoologia
Autores: Hartmann,Marilia T; Hartmann,Paulo A; Haddad,Célio F. B.
Reproductive modes and size-fecundity relationships are described for anurans from Picinguaba, a region of Atlantic rainforest on the northern coast of the state of São Paulo, Brazil. We observed 13 reproductive modes, confirming a high diversity of modes in the Atlantic rainforest. This diversity of reproductive modes reflects the successful use of diversified and humid microhabitats by anurans in this biome. We measured the snout-vent length of 715 specimens of 40 species of anurans. The size-fecundity relationship of 12 species was analyzed. Female snout-vent lengths explained between 57% and 81% of clutch size variation. Anurans with aquatic modes laid more eggs than those with terrestrial or arboreal modes. Larger eggs were deposited by species with...

When everything is not everywhere but species evolve: an alternative method to model adaptive properties of marine ecosystems
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Sauterey, Boris; Ward, Ben A.; Follows, Michael J.; Bowler, Chris; Claessen, David.
The functional and taxonomic biogeography of marine microbial systems reflects the current state of an evolving system. Current models of marine microbial systems and biogeochemical cycles do not reflect this fundamental organizing principle. Here, we investigate the evolutionary adaptive potential of marine microbial systems under environmental change and introduce explicit Darwinian adaptation into an ocean modelling framework, simulating evolving phytoplankton communities in space and time. To this end, we adopt tools from adaptive dynamics theory, evaluating the fitness of invading mutants over annual timescales, replacing the resident if a fitter mutant arises. Using the evolutionary framework, we examine how community assembly, specifically the...

Some considerations for analyzing biodiversity using integrative metagenomics and gene networks
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Bittner, Lucie; Halary, Sebastien; Payri, Claude; Cruaud, Corinne; De Reviers, Bruno; Lopez, Philippe; Bapteste, Eric.
Background:  Improving knowledge of biodiversity will benefit conservation biology, enhance bioremediation studies, and could lead to new medical treatments. However there is no standard approach to estimate and to compare the diversity of different environments, or to study its past, and possibly, future evolution. Presentation of the hypothesis:  We argue that there are two conditions for significant progress in the identification and quantification of biodiversity. First, integrative metagenomic studies - aiming at the simultaneous examination (or even better at the integration) of observations about the elements, functions and evolutionary processes captured by the massive sequencing of multiple markers - should be preferred over DNA barcoding projects...

Within outlying mean indexes: refining the OMI analysis for the realized niche decomposition
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Karasiewicz, Stephane; Doledec, Sylvain; Lefebvre, Sebastien.
The ecological niche concept has regained interest under environmental change (e.g., climate change, eutrophication, and habitat destruction), especially to study the impacts on niche shift and conservatism. Here, we propose the within outlying mean indexes (WitOMI), which refine the outlying mean index (OMI) analysis by using its properties in combination with the K-select analysis species marginality decomposition. The purpose is to decompose the ecological niche into subniches associated with the experimental design, i.e., taking into account temporal and/or spatial subsets. WitOMI emphasize the habitat conditions that contribute (1) to the definition of species' niches using all available conditions and, at the same time, (2) to the delineation of...

The French National Institute of Ecology and Environment (INEE) aims at fostering pluridisciplinarity in Environmental Science and, for that purpose, funds ex muros research groups (GDR) on thematic topics. Trophic ecology has been identified as a scientific field in ecology that would greatly benefit from such networking activity, as being profoundly scattered. This has motivated the seeding of a GDR, entitled “GRET”. The contours of the GRET's action, and its ability to fill these gaps within trophic ecology at the French national scale, will depend on the causes of this relative scattering. This study relied on a nationally broadcasted poll aiming at characterizing the field of trophic ecology in France. Amongst all the unique individuals that fulfilled...

Autores: Blanchard, Julia L.; Coll, Marta; Trenkel, Verena; Vergnon, Remi; Yemane, Dawit; Jouffre, Didier; Link, Jason S.; Shin, Yunne-jai.
Time-series of ecological and exploitation indicators collected from 19 ecosystems were analysed to investigate whether there have been temporal trends in the status of fish communities. Using linear and non-linear statistical methods, trends are reported for six indicators (mean length of fish in the community, mean lifespan, proportion of predatory fish, total biomass of surveyed species, mean trophic level of landings, and inverse fishing pressure), and the redundancy of these indicators across ecosystems is evaluated. The expected direction of change for an ecosystem that is increasingly impacted by fishing is a decline in all indicators. A mixture of negative and positive directions of change is recorded, both within and among all ecosystems...

The large-scale distribution pattern of megafauna communities along the Mediterranean middle slope was explored. The study was conducted between 500 and 800 m depth where deep-water fishery occurs. Although community studies carried out deeper than 500 m are partly available for some geographic areas, few large-scale comparative studies have been carried out. Within the framework of the MEDITS survey programme, we compared the megafauna community structure in ten geographical sub-areas (GSAs) along the Mediterranean coasts. Additionally, the spatial distribution of fishing was analysed using vessel monitoring by satellite information. Overall, the community showed a significant difference between sub-areas, with a decreasing eastward pattern in abundance...

Assessment of indicator trends related to exploited demersal fish populations and communities in the Mediterranean
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: MEDITS.
Since 1994, Mediterranean research organisations have carried out yearly standardized bottom trawl surveys along the coasts of the Mediterranean Sea from Gibraltar to the Aegean Sea (Medits surveys). A dynamic indicator-based approach to the assessment of multi-stock fisheries has been applied to the data series obtained from these surveys by an international working group involving all the scientific teams contributing to the data collection process. The application was done according to the 13 GFCM geographical sub-areas sampled by the Medits surveys. While reference points for a lot of fished populations and community indicators are seldom available, reference directions are well established for some indicators, giving guidelines for fishery management....

Implications of morphological and functional traits for trophic relationships within fish communities and marine trophic network architecture
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Cachera, Marie.
A current issue in ecology is to understand the contribution of biodiversity to ecosystem functioning and notably to comprehend how inter- and intra-specific trait variation affects trophic interactions between individuals and species, the trophic organization of communities and trophic network architecture. Particularly, morphology has historically been considered as a main determinant of organisms’ ecology, which led to the field of ecomorphology, and, from a functional perspective, is expected to influence trophic relationships and other ecological functions performed by species. This thesis aimed at studying the trophic organization of a marine fish community and its dependency on morphological and functional trait variation between and within species....

Assembly rules in Muscid Fly assemblages in the grasslands Biome of Southern Brazil
Provedor de dados: Neotropical Entomology
Autores: Krüger,Rodrigo F; Carvalho,Claudio J B de; Ribeiro,Paulo B.
The distribution of muscid species (Diptera) in grasslands fragments of southern Brazil was assessed using null models according to three assembly rules: (a) negatively-associated distributions; (b) guild proportionality; and (c) constant body-size ratios. We built presence/absence matrices and calculated the C-score index to test negatively-associated distributions and guild proportionality based on the following algorithms: total number of fixed lines (F L), total number of fi xed columns (F C), and the effect of the average size of the populations along lines (W) for 5000 randomizations. We used null models to generate random communities that were not structured by competition and evaluated the patterns generated using three models: general, trophic...

Insect-plant interactions: new pathways to a better comprehension of ecological communities in Neotropical savannas
Provedor de dados: Neotropical Entomology
Autores: Del-Claro,Kleber; Torezan-Silingardi,Helena M.
The causal mechanisms shaping and structuring ecological communities are among the most important themes in ecology. The study of insect-plant interactions in trophic nets is pointed out as basic to improve our knowledge on this issue. The cerrado tropical savanna, although extremely diverse, distributed in more than 20% of the Brazilian territory and filled up with rich examples of multitrophic interactions, is underexplored in terms of biodiversity interaction. Here, this ecosystem is suggested as valuable to the study of insect-plant interactions whose understanding can throw a new light at the ecological communities' theory.

Diversity of Calliphoridae (Insecta: Diptera) in Hudson, Argentina
Provedor de dados: Neotropical Entomology
Autores: Centeno,Néstor; Almorza,David; Arnillas,Carlos.
Blowflies have sanitary and forensic importance, and different levels of association with human settlements (synanthropy). Therefore, specific diversity changes in each site could be used as an indicator of the anthropic impact. In this study, the community of Calliphoridae in Hudson (Argentina) was sampled in three sites with different degrees of Synanthropy (natural, rural and urban). Flies were attracted with bait and collected with an insect net. Twelve samples were collected in each site and both Simpson and Shannon diversity indexes were calculated. The Natural area was the most diverse. The other two areas showed no significant differences between them. The diversity was higher in the middle of spring and in late summer, and lower at the end of...

Geographical transition zone of Solenopsis fire ants (Hymenoptera: Formicidae) and Pseudacteon fly parasitoids (Diptera: Phoridae) in the state of São Paulo, Brazil
Provedor de dados: Neotropical Entomology
Autores: Pesquero,MA; Dias,AMPM.
Solenopsis saevissima (Smith) and Solenopsis invicta Buren are the most abundant and widely distributed fire ants in Brazil. The occurrence of the two fire ant species and of their parasitoids Pseudacteon spp. is described for a climatic and phytophysiognomic transition area in the state of São Paulo. Both fire ant species have a parapatric distribution, apparently determined by the climate: S. saevissima predominates in the north part of São Paulo (Aw climate), while S. invicta in the south (Cfa climate). A sympatric area is observed between the latitudes 21ºS and 23ºS. Two different communities of parasitic decapitating flies were associated with S. saevissima in the north and with S. invicta in the south, with a sympatric area in the municipality of São...

Abstract Forest fragments in urban areas have many habitat resources that frogs use for refuge, reproduction and growth. Knowledge of an anuran assembly is the first step towards understanding the importance of these forest fragments in areas highly threatened by anthropogenic actions. We sampled anurans during the day and night from November 2012 to August 2013 through visual and acoustic surveys. We found 333 individuals belonging to 19 species. The highest richness and abundance were recorded in January whereas the lowest richness and abundance were recorded in June. Most species were found in open areas. Our results highlight the importance of well-studied urban fragments for the anuran community. The conservation of these habitats may ensure the...

Pastoral Communities in Nigeria: Another Case of Marginalisation
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Aderinoye-Abdulwahab,   S.A.; Adefalu,   L.L.
The study which was conducted in rural communities of Kwara State, Nigeria set to uncover how pastoralists‟ families cope with their livelihoods when their husbands have gone grazing with the cattle. It examined the social and financial coping strategies of their families through Focus group discussions and interviews with pastoralists, their wives and some extension agents. The findings revealed that the pastoralists live in marginalised conditions and they lack access to social services needed to boost their living conditions. The study recommended increased social networks by government and agricultural bodies to improve on the livelihoods of these people.

Gender and Local Floodplain Management Institutions--A Case Study from Bangladesh
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Sultana,   Parvin; Thompson,   Paul M.
Floodplain wetlands are the major common pool natural resource in Bangladesh. Mostly men fish, and both men and women collect aquatic plants and snails. Case studies contrast a women-only, men-only, and mixed community based organization (CBO), each of which manages a seasonal floodplain wetland. The two CBOs in which women hold key positions are in Hindu communities where more women use aquatic resources, work for an income, and belong to other local institutions. In the oldest of these CBOs, more women have gradually become office bearers as their recognition in the community has grown. In the Muslim community, only a few women collect aquatic resources and in this community most women do not perceive floodplain natural resource constraints to be very...

Mudanças na esfera do trabalho: novos modelos de produção e comunicação
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Siqueira,   Euler David de.
Descartes’ thought in the 17th century announces the dawning of Modern Age. One of his heritages was the notion that we could get to know further about nature, reducing the complex to its simplest parts. This form of thinking has made us see reality as one made up of parts. The explanation of such parts would enable us to number, ordenate and understand the all. The stratification and hierarchyzation of what one calls society in parts, similar to an organism or as a system formed by economy, communication, language, religion, politics, State, rights, has fomented the idea that such spheres find themselves separated, whereas they are not in fact. This article means to develop the idea that social reality, when seen as a whole, may be able to gather together...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Cho,   Seong-Hoon; Clark,   Christopher D.; Park,   William M.
A two-stage multinomial logit selection model is used to model the relationship between demographic characteristics and housing density across Tennessee’s six metropolitan statistical areas.  The study finds that there is both spatial correlation and heterogeneity in the most densely populated area, has the least amount of spatial correlation among housing density at the neighborhood level, while Johnson City, which has the lowest overall housing density, has the highest degree of spatial correlation.

Bioeconomic Model of Community Incentives for Wildlife Management Before and After CAMPFIRE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Fischer,   Carolyn; Muchapondwa,   Edwin; Sterner,   Thomas.
This paper formulates a bioeconomic model to analyze community incentives for wildlife management under benefit-sharing programs like the Communal Areas Management Programme for Indigenous Resources (CAMPFIRE) in Zimbabwe. Two agents influence the wildlife stock: a parks agency determines hunting quotas, and a local community chooses to either aid or discourage outside poachers. Wildlife generates revenues from hunting licenses and tourism; it also intrudes on local agriculture. We consider two benefit-sharing regimes: shares of wildlife tourism rents and shares of hunting licenses. Resource sharing does not necessarily improve community welfare or incentives for wildlife conservation. Results depend on the exact design of the benefit shares, the size of...

Necrophagous Diptera associated with wild animal carcasses in southern Brazil. The aim of this study was to acquire a better knowledge concerning the diversity of necrophagous Diptera that develop on wild animal carcasses. For this purpose, the decomposition of six wild animal carcasses was observed in order to collect and identify the main species of necrophagous flies associated with the decomposition process. The carcasses were found on highways near the cities of Pelotas and Capão do Leão in the initial stage of decomposition, with no significant injuries or prior larval activity. Four wild animal models were represented in this study: two specimens of Didelphis albiventris Lund, 1840; two Tupinambis merianae Linnaeus, 1758; one Nothura maculosa...

Effects of habitat and landscape characteristics on medium and large mammal species richness and composition in northern Uruguay
Provedor de dados: Revista Brasileira de Zoologia
Autores: Andrade-Núñez,María José; Aide,T. Mitchell.
The increasing world population and demand for food and other products has accelerated the conversion of natural habitats into agricultural lands, plantations and urban areas. Changes in habitat and landscape characteristics due to land-use change can have a significant effect on species presence, abundance, and distribution. Multi-scale approaches have been used to determine the proper spatial scales at which species and communities are responding to habitat transformation. In this context, we evaluated medium and large mammal species richness and composition in gallery forest (n = 10), grassland (n = 10), and exotic tree plantation (n = 10) in a region where grasslands have been converted into exotic tree plantations. We quantified mammal species...

Autores: Siqueira,Carla C; Vrcibradic,Davor; Dorigo,Thiago A; Rocha,Carlos F. D.
The anurofauna inhabiting higher montane Atlantic forest areas in southeastern Brazil, which often attain heights of more than 2000 m, is still insufficiently known. In this study, we present data on anuran species composition and abundances in two high-altitude (i.e. &gt; 1000 m) sites within the Parque Estadual dos Três Picos (PETP), in the state of Rio de Janeiro. Field surveys were done at altitudes between 1100 and 1900 m above sea level. We recorded 35 species during our study, adding 22 records to the set of anuran species previously known to occur within the PETP. The stability of the species accumulation curve, as well as the richness estimations, showed that the sampling methodology employed and the total sampling effort were appropriate to...

San Agustín bay is one of the most important bays in the Huatulco National Park because it includes the broadest coral reef surface of this park, which supports a great diversity of fish species. The importance of the present work is that describes quantitatively, for first time, the fish assemblage of this reef area. Visual censuses were realized on transects, according to the coral reef size, on coral and rocky reefs, and coral rubble environments. 64 species, 46 genus and 29 families were registered. Seasonal variation in fish assemblage was observed; reflecting the influence of pelagic shoaling species associated with the Gulf of Tehuantepec upwelling, during the dry season. Thus species were Selar crumenophthalmus, Caranx caninus, and Sardinops...

We studied the effects of fire on the structural attributes of a Spartina densiflora salt marsh. The study was carried out from November 1995, spring (N95S) to December 1996, late spring (D96LS). In November 1995, we installed 37 permanent plots. In January 1996, 32 of the plots were accidentally burned (B) and the remaining were not burned (NB). Vegetation on each plot was sampled seasonally, plant species were identified and cover-abundance was estimated. We analyzed and compared seasonal variations in plant species richness, diversity, composition and cover-abundance in burned and non-burned plots. In addition, we analyzed variations in biological types (forbs, graminoids) and types of life cycles (annuals, perennials) in B and NB plots before and after...

Comments on plant-herbivore-parasitoid interactions in two cerrado areas of Southern Brazil
Provedor de dados: Zoologia
Autores: Caldas,Astrid; Passos,Fernando de C.
This work describes some interactions between lepidopteran larvae and braconid parasitoids on a group of plants at two sites. There was no significant difference in parasitoid diversity between the sites (Shannon index, p&lt;0.05), and similarity was 62.5%, estimated through Sorensen's index. The diversity of hosts was also not different (p&lt;0.05), but the similarity of host diversity was only 28.5%. This suggests that the parasitoids have strategies for maintaining similar reproduction rates, population densities and communities in areas with different potential hosts.

Ecologia de comunidades das larvas de Trichoptera Kirby (Insecta) em dois córregos de primeira ordem da Serra dos Pireneus, Pirenópolis, Goiás, Brasil
Provedor de dados: Zoologia
Autores: Oliveira,Leandro Gonçalves; Bispo,Pitágoras da Conceição.
The Trichoptera fauna in two first-order streams of Serra dos Pireneus. Goiás State, was studied from June/1993 to July/1994. The Trichoptera larvae abundances were lower in the rainy season in the two streams. The temporal distributions of the functional groups (feeding categories) was similar in both streams. The ordination by Detrended Correspondence Analysis (DCA) detected a higher temporal heterogeneity of the Trichoptera community in one of the sampling stations, probably associated with higher discharge variation. There is a large variation of abundance of some genera between the two studied streams.

Ecological strategies of Al-accumulating and non-accumulating functional groups from the cerrado sensu stricto
Provedor de dados: Anais da Academia Brasileira de Ciências
Autores: Souza,Marcelo C. de; Bueno,Paula C.P.; Morellato,Leonor P.C.; Habermann,Gustavo.
The cerrado's flora comprises aluminum-(Al) accumulating and non-accumulating plants, which coexist on acidic and Al-rich soils with low fertility. Despite their existence, the ecological importance or biological strategies of these functional groups have been little explored. We evaluated the leaf flushing patterns of both groups throughout a year; leaf concentrations of N, P, K, Ca, Mg, S, Al, total flavonoids and polyphenols; as well as the specific leaf area (SLA) on young and mature leaves within and between the groups. In Al-accumulating plants, leaf flushed throughout the year, mainly in May and September; for non-accumulating plants, leaf flushing peaked at the dry-wet seasons transition. However, these behaviors could not be associated with...

Bird community as an indicator of biodiversity: results from quantitative surveys in Brazil
Provedor de dados: Anais da Academia Brasileira de Ciências
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...

The role of phytophysiognomies and seasonality on the structure of ground-dwelling anuran (Amphibia) in the Pampa biome, southern Brazil
Provedor de dados: Anais da Academia Brasileira de Ciências
Autores: MARAGNO,FRANCIÉLE P.; SANTOS,TIAGO G.; CECHIN,SONIA Z.
ABSTRACTConsidering that habitat use by amphibians is related both with climate and environmental features, we tested the hypothesis that anuran assemblages found in different phytophysiognomies and in different seasons vary in structure. Additionally, we searched for species which can be indicators of habitat and seasons. The study was conducted in the Pampa biome, southern Brazil. Sampling was done through pitfall traps placed in three phytophysiognomies: grassland, ecotone grassland/forest; and forest. The seasonality factor was created by grouping months in warn and cold seasons. Sixteen species were found and the assemblages were influenced both by phytophysiognomies and climatic seasonality. In a paired comparison, the three phytophysiognomies...

Autores: Sabbag,Ariadne Fares; Zina,Juliana.
We surveyed anuran amphibians in a riparian forest fragment of the Córrego do Espraiado, located at the Universidade Federal de São Carlos, Municipality of São Carlos, state of São Paulo, southeastern Brazil. During March 2009 and February 2010 we did weekly surveys in which we recorded 13 anuran species. The species showed a seasonal reproductive activity. In addition, we found a positive correlation between the number of reproductively active species and photoperiod. We also found that the studied community was more similar to those of transitional areas between the Atlantic Forest and Cerrado than those of the nearby Cerrado fragments.

Autores: Silva-Junior,Luiz Constantino; Santos,Sérgio Ricardo; Macedo,Márcio Chagas; Nunan,Gustavo Wilson; Vianna,Marcelo.
Abstract: A total of 1,471 specimens of 16 species of flatfishes (Pleuronectiformes) were caught during 48 sampling campaigns between July 2005 and June 2007 at ten stations in Guanabara Bay, Rio de Janeiro, Brazil. Paralichthyidae was the dominant family, with Etropus crossotus as the dominant species. The outer stations, especially those on the western side of the lower estuary, were distinguished as a result of their higher abundance of flatfishes and number of species. The spatial distribution of E. crossotus and its population structure indicate that this species is an estuarine resident despite the apparent reduction in its area of occupation within the estuarine complex. Among the other species, nine were classified as marine stragglers (Achirus...

Ecological aspects of the surf-zone ichthyofauna of Itamambuca Beach, Ubatuba, SP
Provedor de dados: Biota Neotropica
Autores: Gondolo,Guilherme Fernandez; Mattox,George Mendes Taliaferro; Cunningham,Patricia Teresa Monteiro.
Sandy beaches are among the most extensive environments in Brazil and are generally threatened by disorderly urban growth due to their location along the coast, where human populations tend to concentrate. This is especially true in southeastern Brazil, where the largest urban areas are located. Thus, better knowledge regarding these natural resources is of considerable importance. The surf zone of sandy beaches is inhabited by a number of fish species, including juveniles seeking both food and shelter from predators. An ecological survey was conducted in the surf zone of Itamambuca beach in the city of Ubatuba, São Paulo State, Brazil, in order to evaluate the composition, structure and dynamics of the fish fauna using community descriptors.

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...

Provedor de dados: Brazilian Archives of Biology and Technology
Autores: Frenedozo,Rita de Cássia.
Studies were carried out on the phenological patterns and dispersion of a plant community developed naturally after limestone mining operations, in accumulated materials of wastes (spoil banks). The objectives were to focus the seasonality of plant reproductive in a degraded environment; to analyze the community according to dispersal syndrome and to know about plant resources for the animals Monthly observations of flowering and fruiting patterns of the community were done, comparing the herbaceous, shrubs and woody species. Proportion of anemochorous and autochorous was higher in the herbaceous and shrubby strata. The zoochorous ones, on the contrary, were more frequent in the woody stratum. This study showed that natural introduction of the animals at...

Autores: Mocelin,Clei Angelo; Santos,Rodrigo Pires dos.
To assess the adequacy of medical prescriptions for community-acquired pneumonia at the emergency department of the Hospital de Clínicas de Porto Alegre, we conducted a prospective cohort study, from January through April 2011. All patients with suspected pneumonia were selected from the first prescription of antimicrobials held in the emergency room. Patients with a description of pneumonia, community-acquired pneumonia, respiratory infection, or other issues related to community-acquired pneumonia were selected for review. Two-hundred and fifteen patients were studied. Adherence to the hospital care protocol was: 11.2% for the initial recommended tests (chest X-ray and collection of sputum sample), 34.4% for blood cultures, and 92.1% for the...
