Apesar de ser reconhecido como animal símbolo do estado, nenhum trabalho acerca dos comportamentos dessa ave foi desenvolvido no estado. Este trabalho teve como objetivo qualificar e quantificar o repertório comportamental de V. chilensis. Observações dos comportamentos dessa ave foram feitas em uma área de campo com oito hectares, no município de Torres, RS, entre dezembro de 2017 e novembro de 2018, totalizando 143 horas de observação. Utilizou-se a metodologia de observação de todas as ocorrências e observação de animal focal, coletando-se dados de frequência de ocorrência e duração de cada comportamento. Com os dados construiu-se um etograma. Registrou-se 23 comportamentos divididos em cinco categorias: locomoção, manutenção, alimentação, social-agonista e reprodução. Identificaram-se três formas de vocalização distintas em sonoridade, duração e ocasião, o que sugere diferentes funções para cada uma. As análises comprovaram a variação da maior parte dos comportamentos ao longo dos meses do ano, tanto em frequência como em duração. Constatou-se o aumento dos comportamentos sociais-agonistas e reprodutivos durante a estação reprodutiva, enquanto outras categorias como alimentação e manutenção apresentaram diminuição nesse período, havendo maior empenho dos animais na proteção dos ninhos e filhotes. O trabalho permitiu a caracterização dos comportamentos de V. chilensis no sul do Brasil, auxiliando no entendimento das relações entre espécie e ambiente típico da região.","PeriodicalId":56300,"journal":{"name":"Iheringia Serie Zoologia","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78138695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Macroinvertebrate communities were seasonally sampled in eight intermittent wetlands differing according to the occurrence of nesting colonies of waterbirds (four with the presence of rookeries; four without). The influence of nutrients and water and sediment physicochemical variables on macroinvertebrate communities was also assessed. The community structure of aquatic macroinvertebrates was not affected by the presence of colonies of nesting waterbirds. Rather, macroinvertebrate communities varied seasonally and they were influenced by water-level environmental variables. Richness and composition changed among seasons and were influenced by nutrients and water physicochemical variables. Water turbidity and total dissolved solids influenced macroinvertebrate richness, while water nutrients affected macroinvertebrate abundance. Our results indicate that the lack of effect of nesting waterbirds on macroinvertebrates is possibly due to the variation in the composition of avian species and their reduced population sizes, and in such cases, any effects of birds on macroinvertebrates can be overridden by water chemistry and seasonal changes in intermittent wetlands.","PeriodicalId":56300,"journal":{"name":"Iheringia Serie Zoologia","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72489553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sampling was carried out in the dry (May and August/2016 and August/2017) and rainy seasons (November/2016 and February and November/2017). Individuals were identified at the family level and classified according to functional feeding group (FFG). There were 3,776 individuals, in which Chironomidae was the most abundant taxon with 2,226 organisms. The FFG with the highest number of individuals and species richness were collector-gatherer and predator, respectively. The species richness was higher in the dry season than in the rainy season. The ordinance generated by NMDS showed that there was no distinction in the composition of the assemblage between the dry and rainy seasons. Seasonal variations do not alter the abundance and composition of the benthic macroinvertebrate assemblage, but the species richness does decrease in rainy seasons.","PeriodicalId":56300,"journal":{"name":"Iheringia Serie Zoologia","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82884479","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We selected 24 strict nature reserves and nine sustainable-use protected areas. We used data from inventories and complemented with data from the literature. We compared strict and sustainable-use protected areas, and tested whether the bat assemblages varied between habitat types. We tested the effect of geographic distance on the dissimilarity between bat assemblages, as well as the relationship between species composition and the size, mean altitude of the protected area, and capture effort. We compiled a total of 34,443 capture records, involving 67 species. Three species were captured only once, which raises cause for concern. Bat assemblages did not vary between protected area categories, but did vary among habitats with less than 1,000 captures. Assemblages were more similar to one another in geographically proximate areas. The size of the protected area and capture effort did not affect the composition of the bat assemblages, but altitude did influence this parameter. The Atlantic Forest is a priority biome for research and conservation, and reliable data on species distributions are essential for the development of conservation strategies.","PeriodicalId":56300,"journal":{"name":"Iheringia Serie Zoologia","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86464030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is the fifth update since the first compilation based on a reasonably complete geographic coverage of the state, published by William Belton in 1978, and the second produced by a regional (informal) committee. It is also the first to widely use citizen science contributions available on shared portals and digital databases on the internet. 43 taxa were added, resulting in a final list with 704 species, 6.5% more than in the previous assessment in 2010. Two species were replaced due to taxonomic changes. Documentation for inclusions based on unpublished records is indicated or published here. We also updated the documentation of another 20 species previously included in the list. Inclusions represent mainly migrants recorded in the state as vagrants or irregular visitors (22), but also cases of recent range expansion (especially from the north) and previously overlooked resident or migratory taxa. The average rate of additions (over six species per year) was 30% higher than in the previous period and is expected to accelerate. The percentage of accepted species without documented records in the state decreased from 1.8% in 2010 to 0.7% in the current list. We attribute these results to a better spatial and temporal coverage of the state in recent years, mainly due to the increasing contribution of amateurs, who accounted for 60% of the new occurrences. In contrast, the percentage of species documented by museum specimens has decreased steadily over time (currently at 84%). Investment in scientific research and collection of voucher specimens in the state should keep pace with the growing interest birds arouse in society, due to the importance and usefulness of museum specimens.","PeriodicalId":56300,"journal":{"name":"Iheringia Serie Zoologia","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2018-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76247680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the macrofauna associated with these beds, crustaceans are considered essential for the whole ecosystem functioning. However, knowledge about the associated community of decapod crustaceans in assemblages of T. testudinum and H. wrigthii is still scarce, particularly outside of protected areas. Here we report eight new decapod species for the Paraguaná Peninsula (Falcón State, Venezuela) in association with intermixed seagrass beds: Achelous tumidulus Stimpson, 1871, Alpheus aff. floridanus Kingsley, 1878, Chorinus heros (Herbst, 1790), Clibanarius antillensis (Stimpson, 1859), Clibanarius sclopetarius (Herbst, 1796), Latreutes parvulus (Stimpson, 1866), Panopeus occidentalis Saussure, 1857, and Processa fimbriata Manning & Chace, 1971. These records represent habitat extensions and fill gaps in the geographical distribution of the species along the northern coast of South America. Furthermore, we found that statistical differences in decapod species abundance and composition are likely to be caused by the joint action of coverage and heterogeneity of the beds. Our results indicate that typical Caribbean species were the most influential in the community; nevertheless, the abundance of juvenile Penaeus schmitti Burkenroad, 1936 was notable, since they have rarely been found in these habitats. This finding highlights the role of non-protected areas as nursery habitats for economically important species. Our results show that seagrass meadows in the Paraguaná Peninsula reflect overall good health when compared to other Caribbean zones, representing an important habitat for the maintenance of crustacean populations.","PeriodicalId":56300,"journal":{"name":"Iheringia Serie Zoologia","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2018-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86163557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
