Os principais predadores aquáticos estão representados pelos invertebrados da classe Insecta, que se alimentam de organismos vertebrados e/ou invertebrados. Dentre os vertebrados, os girinos são os mais consumidos. Este experimento estudou a atividade predatória dos insetos aquáticos (Odonata: Libellulidae e Coleóptera: Hydrophilidae) sobre girinos de Rhinella sp. e Physalaemus sp. na cidade de Capitão Poço, Pará, Brasil. O experimento contou com seis tratamentos realizados em duas fases (dia e noite). Foram observadas diferenças significativas somente entre os tratamentos 1 (controle) e 2 (Libellulidae) (F= 7,21; p= 0,00). A atividade predatória dos insetos foi realizada em ambas as fases, não havendo diferenças significativas (F= 1,33; p= 0,26). O sucesso da família Libellulidae está relacionado as estratégias e aspectos morfológicos que suas larvas utilizam no ato de predação. Diferentemente, a família Hydrophilidae, possui características que podem ter colaborado na baixa atividade predatória observada.","PeriodicalId":41699,"journal":{"name":"Acta Brasiliensis","volume":"1 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2023-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42576846","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 present study examined the influence of decomposition time on the: (i) composition of the sarcosaprophagous dipterofauna; (ii) sexual proportion of the collected specimens; and (iii) the stage of sexual maturity of female flies (Calliphoridae and Sarcophagidae). For this, we used chicken liver with different decomposition times (0h, 24h, 48h, and 76h) for the collection of adult flies. The results showed that: i) the assemblages were most diverse and abundant in more decomposed baits; ii) Calliphoridae was the most abundant taxa in all treatments; iii) the reproductive stage varied according to the age of the substrate, with high rates of mature or pregnant females in the older substrates; and iv) the number of males blowflies was higher in older baits, but it did not vary for flesh flies. Thus, this work demonstrates experimentally that the substrate age is an influencing factor in the composition of sarcosaprophagous flies’ assemblage, and it indication of the dipterans potential as primary or secondary colonizers throughout colonization of ephemeral resources.","PeriodicalId":41699,"journal":{"name":"Acta Brasiliensis","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2023-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46602033","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 current study aimed to determine the productive microorganisms for waste biodegradation. Ten samples were collected from different areas of Karachi waste dump sites. The identification and characterization of isolates were done by morphological and biochemical tests. The isolated microbes were qualitatively screened for the action of making industrially key bio-enzymes. The potential enzymes producing microbes were subjected to waste degradation test for 90 days. Changes of odor, color and weight loss of decomposing garbage were noted. The highest degradation ability in term of weight loss was shown by Aspergillus (SSI14) and Bacillus (SSI6). Four metals (zinc sulphate, cadmium chloride, copper sulphate and iron sulphate) were chosen for the purpose of metals tolerance test and minimum inhibitory concentration (MIC) of the isolated microbial strains. Current study reported that Zn was found to be more lethal in in comparison to Cu and Fe. Molecular identification of the isolated microbes was done by polymerase chain reaction. The microbial strains were characterized by the polymerase chain reaction (PCR) followed by confirmation of product by agarose gel electrophoresis. The findings can be served as baseline data to develop microbial apparatus for biodegradation and management of solid waste.","PeriodicalId":41699,"journal":{"name":"Acta Brasiliensis","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2023-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47477998","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}

(Anacardiaceae) is a woody medicinal plant interesting to research and conservation due to timber extraction, high pharmacological potential and cultural value in the Brazilian semi-arids. In this research, we modeled the potential distribution of the species in the Neotropical, identified the climate limiting factors of its distribution and measured the percentage of adequate protected areas. The model was generated in the Maxent software, through the combination of 469 registers of the species occurrence and nine climate variables from the WorldClim data base and presented good development (AUC = 0.976). The potentially adequate areas were estimated along the dry diagonal in South America, in addition to fragmented areas at the coast of Peru and Ecuador. Precipitation, temperature and atmospheric humidity were the most influential variables on the prediction of climatically viable areas for the species. The results indicate low representation of protected areas (0.003%) in highly adequate areas, which demonstrates the necessity of expansion, implementation of measures of conservation and management of S. brasiliensis. The findings in this study, therefore, can be used for scientific support on delineating these measurements.","PeriodicalId":41699,"journal":{"name":"Acta Brasiliensis","volume":"1 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2023-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68222143","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}

Soil chemical and physical analyzes were performed and mineralization and nitrification rates were determined. The forms of organic, inorganic and particulate nitrogen in water were determined by spectrophotometry. Two collections were carried out, one in the dry season (October and November 2019) and another in the rainy season (February and March 2020), in two environmental preservation areas, Estação Veracel Private Natural Heritage Reserve - (Atlantic Forest) and Chapada Diamantina National Park (Cerrado), with five small watersheds sampled in each biome. The N concentration in litterfall was similar in both biomes, with averages of 0.69%. In relation to soil and water, N concentrations were higher in AF compared to CR, with concentrations of 0.95 ± 0.40 and 0.59 ± 0.14 µg.Ng-1 of nitrate in the soils of AF and CR, respectively, and 3.53 ± 2.51 µM of nitrate in water in AF and 0.76 ± 0.78 µM in CR.","PeriodicalId":41699,"journal":{"name":"Acta Brasiliensis","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46831032","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}
