For the western region of Para State, there is no information about the presence of hemoparasites in Iguana iguana and the possible hematological alterations they cause. Thus, this study aimed to identify the presence of hemoparasites, and the hematological alterations caused by them, in I. iguana in the municipality of Santarem, Para, Brazil. The search for hemoparasites was performed on blood smears with hematological dye analyzed under a light microscope at 1,000x magnification. Hematological values were obtained by counting in a Neubauer chamber using 0.01% toluidine blue reagent. Hemoparasite infection was observed in 18 animals (10 males and 8 females). There were no statistically significant differences between genders and leukocyte, thrombocyte and red blood cell values. There is hemoparasite infection in I. iguana in the region. The relationship between this hemoparasite and the host appears to have little pathogenicity in causing significant changes in leukocyte, red blood cell and thrombocyte values.","PeriodicalId":29999,"journal":{"name":"Biotemas","volume":" ","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2020-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5007/2175-7925.2020.e67915","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45645661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study was carried out in a secondary forest on the banks of Igarape Dispensa, on the properties of family farmers. Two plots measuring 10 m x 25 m were established in each area, in which all woody and non-woody individuals with DBH ≥10 cm present within the limits of each sample unit were inventoried. Floristic composition was analyzed, and richness and diversity were estimated. In the secondary forest, 279 individuals, 49 species, 43 genera and 26 families were identified. The family with the largest number of species and individuals was Fabaceae. The Shannon-Weaver (H’) diversity index was 3.43 nats/ind, considered to be of satisfactory diversity. The species found have the potential to be used in regeneration proposals for APPs of Igarape Dispensa.","PeriodicalId":29999,"journal":{"name":"Biotemas","volume":"33 1","pages":"1-11"},"PeriodicalIF":0.0,"publicationDate":"2020-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5007/2175-7925.2020.e70345","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41417412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study sought to quantify the richness and analyze the occurrence frequency of the medium- and large-sized terrestrial mammals of a 76.5 ha LR in the municipality of Pedra do Indaia in Minas Gerais State, Brazil. Data collection lasted for 28 months and was based on the following sampling methods: direct and indirect observation and camera trapping. We registered 25 species from seven orders and 14 families. The most represented orders were Carnivora, Cingulata and Rodentia, while Lagomorpha and Didelphimorphia were the least recorded orders. Of the 25 recorded species, six are cited as threatened with extinction on the Minas Gerais Red List and four are cited in the Brazil Red Book of Threatened Fauna. The occurrence of threatened animal species suggests the need to maintain the LR and the native vegetation remnants in order to keep the habitat quality necessary for the persistence of populations and their ecosystem services.","PeriodicalId":29999,"journal":{"name":"Biotemas","volume":"32 1","pages":"79-88"},"PeriodicalIF":0.0,"publicationDate":"2019-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5007/2175-7925.2019v32n4p79","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48870284","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to analyze the diversity of the malacofauna associated with Anomalocardia flexuosa distribution on a tropical sandy beach. Samples were collected bimonthly between April 2016 and February 2018 at 34 points distributed throughout a sandbar. The frequencies of occurrence of the species were calculated, and diversity indices were estimated and correlated with the densities of A. flexuosa. A total of 4,780 individuals from 11 species were obtained. The most frequent species were A. flexuosa and Neritina virginea. There were significant correlations between A. fleuxosa density and diversity, and overlap occurred between mollusks over the collection months and sites. Therefore, targeted catches for this species should also consider all other mollusks to mitigate future damage to malacofauna diversity in the region.","PeriodicalId":29999,"journal":{"name":"Biotemas","volume":"32 1","pages":"51-62"},"PeriodicalIF":0.0,"publicationDate":"2019-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5007/2175-7925.2019v32n4p51","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42726273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The goal of this study was to investigate the effects of urbanization on physicochemical habitat characteristics and evaluate the responses of urbanization on functional feeding groups (FFGs) of invertebrates. Water quality parameters (temperature, conductivity, dissolved oxygen, pH, phosphorus, chlorophyll-a, turbidity and organic matter) and flow parameters were measured in least and severely urbanized areas. FFGs of macroinvertebrates were analyzed and applied as surrogates of ecosystem attributes. The differences in the macroinvertebrate community of the least and severely urbanized areas were assessed using non-metric multidimensional scaling (nMDS) and a permutational multivariate analysis of variance (Permanova). Differences between the least and severely urbanized areas were observed with nMDS. The Permanova also showed a significant difference between the nMDS groups. The least urbanized areas presented greater richness for each FFG. On the other hand, severely urbanized areas presented a major abundance of gathering collectors and predators. Thus, the composition of FFGs responded to habitat alterations that were represented by water quality and the flow parameters.","PeriodicalId":29999,"journal":{"name":"Biotemas","volume":"32 1","pages":"29-44"},"PeriodicalIF":0.0,"publicationDate":"2019-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5007/2175-7925.2019v32n4p29","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45586772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
