In the Brazilian steppe savanna, this situation requires attention because habitats with higher economic value are underrepresented by the protected area system. Between 2009 and 2010, we surveyed 60 sites with differing landscapes such as plateaus, slopes, and lowlands in the Serra de Santana. At each site, we applied standardized bird survey methods and compared the observed and projected richness of each landscape. We recorded 189 species, with the highest species richness in the slope habitat, followed by plateaus, and then lowlands. In the slope habitat, there were more forest-dependent species, as well as more species with high and medium sensitivity to disturbance. Endemic species with high and medium sensitivity to disturbances were restricted to slopes and some fragments of the plateaus. Our results show that the region is an important area due to the high bird species richness and presence of endemic and threatened species. The slope areas were the richest due to more recent human occupation. As priority measures for Serra de Santana, we suggest the control of deforestation and the designation of a protected area that encompasses all the altitudinal variation in the region.","PeriodicalId":54409,"journal":{"name":"Tropical Zoology","volume":"29 1","pages":"189 - 204"},"PeriodicalIF":0.9,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03946975.2016.1235426","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59383033","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}

In the Niger Delta, where it is considered extremely threatened, with very few sightings in the last decades. In this study we document both direct (skins, footprints, scats, etc.) and indirect (village hunter’s interviews) signs of leopard presence in order to reconstruct leopard presence in the Niger Delta, across the period 2000–2015. Data were combined into three survey periods: 2000–2002, 2006–2008 and 2012–2015, and compared with literature data for 1996–1997. Recent skins were recorded in 2.2–4.3% of the villages (n = 39–62). In addition, the leopard was reported to be present by hunters in another 3.3–10.3% of the villages. Overall, some specific sectors of the Delta were recurrently target of both direct and indirect signs of leopard presence (barrier islands and flood forest along the central axis of the River Niger), but all direct sightings occurred in a few barrier islands. In the Niger Delta, there was no evidence of females with cubs since decades and a few skins were the only direct signs of leopard’s current presence. Our results suggest that leopard populations may be functionally extinct in the Niger Delta, with just a few vagrant individuals, in dispersal and/or hunting, being still found. Barrier island forests are apparently the last vegetation zone of the Delta still potentially inhabited by leopards, and deserve careful managements in the years to come.","PeriodicalId":54409,"journal":{"name":"Tropical Zoology","volume":"29 1","pages":"173 - 183"},"PeriodicalIF":0.9,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03946975.2016.1214461","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59382462","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 evaluated the variation in body size traits, sexual dimorphism in populations of a turtle species Acanthochelys spixii across its distribution in Brazil and we described sex ratio in those populations. Description of the size-classes on these populations was also provided. We sampled 86 adults (16 in Minas Gerais (MG) and 70 in Rio Grande do Sul (RS)). The sex ratio was 1:1 in both sampling areas. Females were larger than males, and specimens from RS were larger than those from MG. The posterior-lobe width (PLW) was deemed the most significant sexing variable in a linear discriminant analysis of specimens within each state. Two variables, PLW and maximum carapace width, together distinguished the four groups (males and females in MG and RS) with 77% accuracy. Overall, most body measures were larger for both males and females in the southernmost population, inhabiting higher latitudes and lower temperatures. Regarding sexual size dimorphism, females had larger PLW than males in MG, and all variables were dimorphic in RS, in general females being larger than males.","PeriodicalId":54409,"journal":{"name":"Tropical Zoology","volume":"29 1","pages":"73 - 86"},"PeriodicalIF":0.9,"publicationDate":"2016-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03946975.2016.1164559","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59382721","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}

Upon analysis of prey preferences, they were categorized into different trophic subgroups. Two dendrograms, one based on prey diversity and other on digestive enzymes of studied fish species were constructed through cluster analysis. These dendrograms were compared again with the phylogenetic tree constructed on the basis of the taxonomic positions. The specific nature of the enzymes in two plankti-detritivorous fishes appeared to possess a specific feeding behaviour and dietary preference though no clear predominance among digestive enzymes was observed. However, regardless of different feeding habits, four gobiid species showed similarity in their overall digestive enzyme patterns and clustered together. Despite mixed results, it can be concluded that digestive enzymes may serve as effective indicators of the feeding ecology of fishes, but the physiological requirements to live in specific trophic guilds may differ among families and therefore, influence of phylogeny on the digestive physiology could not be avoided without understanding the evolutionary specializations for these feeding modes in fishes.","PeriodicalId":54409,"journal":{"name":"Tropical Zoology","volume":"29 1","pages":"53 - 72"},"PeriodicalIF":0.9,"publicationDate":"2016-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03946975.2016.1154286","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59382668","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}
