Herein, we perform an extensive review of occurrence records and propose a potential distribution based on ecological niche modeling. In order to confirm species identification, as well taxonomic status along its distribution, we provide morphological and molecular data from analysed specimens. To reach our goals, we compiled data available in the literature and from scientific collections, as well as unpublished data. We identified records of P. centralis in 123 localities, 86 of those records remain unpublished. Consequently, it is possible to extend its range of distribution to the state of Rondônia, Brazil, and also to the Caatinga formation. The Maxent algorithm provided a model of potential distribution consistent with the distribution proposed here. Results indicate that P. centralis has a large distribution associated to open areas of South America (Cerrado, Caatinga and Pantanal), with no evidence that this is a case of species complex. The multiple approach proposed herein, that combines occurrence data from different sources and molecular data to confirm species identification, provided consistent results. Therefore, we recommend that this framework be used as a protocol to assess species distribution in future studies, especially in the case of widely distributed species.","PeriodicalId":54409,"journal":{"name":"Tropical Zoology","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2017-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03946975.2017.1278661","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47169343","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}

For the evaluation of the microhabitat preference we used non-parametric Kruskal–Wallis test and then the Dunn test with the Bonferroni’s correction. In the test of the use of different microhabitats, we used a K proportion test and, when significant, a two proportion Z test was applied between pairs of microhabitats. The species analysed were the hydrophilids Derallus angustus Sharp and Enochrus vulgaris (Steinheil). The results indicate that the spatial distribution of individuals was mostly related to the homogeneity or heterogeneity of the ecosystem. However, when species were analysed individually, the spatial distribution and the use of microhabitat by each of them were different with respect to preference and behaviour. The macrophytes also play a role in the dynamics of these species, as they favour or limit the abundance by modifying the structure thereof.","PeriodicalId":54409,"journal":{"name":"Tropical Zoology","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2017-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03946975.2016.1237067","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45831843","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}

Coordinates, elevation, pH, temperature, conductivity, salinity and dissolved oxygen were measured and their effect on rotifers assessed. A total of 60 species in 5 genera was recorded from the two families. Latitude and temperature had an effect on species richness of Brachionidae. None of the variables affected species richness of Lecanidae, except habitat type, albeit not significantly. Habitat type and conductivity had an effect on species composition of the two families, whereas latitude had an effect only on species composition of Lecanidae. Species richness and composition of the two rotifer families are well documented in Thailand and no or only few additional species are expected. The limnological correlates of rotifer diversity seem to be in part comparable to and in part different from those known from temperate areas, suggesting that there may be general trends in rotifer species richness and composition across different latitudes.","PeriodicalId":54409,"journal":{"name":"Tropical Zoology","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2017-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03946975.2017.1278664","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41721813","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}

A total of 423 male and 449 female shrimps was collected monthly by a bottom-trawl net, from March 2011 to June 2012. The populations of male and female shrimps were dominated by adult shrimps (CL > 15 mm) from January to May. Whereas, the juvenile shrimps were dominant from June to September and the averages of CPUE uptrend in these periods, too. The carapace length and weight relationship demonstrated that growth in both sexes was allometric. The asymptotic carapace length (CL∞) was estimated at 21 mm for males and 27 mm for females. The growth parameter K was calculated as 1.1 Yr −1 for males and 1.2 Yr −1 for females. The total mortality rate for males was more than for females. And the exploitation rates were 0.58 for males and 0.52 for females. The sex ratio identified that it was not a constant 1:1 throughout the year, with 51.49% females. Kiddy shrimps can spawn all year round and have a spawning peak from February to May. The Lm50 was estimated at 19.03 mm carapace length of female shrimps.","PeriodicalId":54409,"journal":{"name":"Tropical Zoology","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2017-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03946975.2017.1278662","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41407005","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 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":null,"pages":null},"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":null,"pages":null},"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}
