| Abstract: The ability of spiders to spread over contiguous areas (Arachnida: Araneae) is directly related to soil management conditions. The objective of this work was to study the effect of land use system (LUS) on the abundance and diversity of soil spider families and their relationship with soil physical and chemical properties. The evaluated LUS were: native forest, eucalyptus reforestation, pasture, crop-livestock integration, and no-tillage crop. Samples were collected in three municipalities of Southern Plateau of Santa Catarina, considered as true replicates, during winter and summer. A total of 270 samples was taken in each area and season. The sampling points were arranged in a grid of 3 × 3 m, spaced by 30 m. We evaluated soil physical,... |

| Uma nova espécie do gênero Tityus C.L. Koch, 1836 (Scorpiones, Buthidae) é descrita dos municípios de Anagé (36'44''14S - 08'08''41W) e Poções (31'47''14S - 21'55''40W) no estado da Bahia, Brasil. Tityus aba n. sp pertence ao grupo Tityusbahiensis (Lourenço, 2002), caracterizado por espécies de tamanho que variam de cinco a sete cm de comprimento, com colorido variando do amarelo - palha ao marrom avermelhado e sem a lâmina mediana basal dilatada nas fêmeas. Neste grupo, aproxima-se das espécies do complexo Tityusstigmurus (Lourenço, 2001). A nova espécie é mais próxima de Tityus stigmurus (Thorell, 1876), Tityus martinpaechi Lourenço, 2001 e de Tityus melici Lourenço, 2003, distinguindo-se da primeira por apresentar o prossoma quase totalmente negro,... |

| The technique of eddy correlation was used to measure the net ecosystem exchange over a woodland savanna (Cerrado Sensu stricto) site (Gleba Pé de Gigante) in southeast Brazil. The data set included measurements of climatological variables and soil respiration using static soil chambers. Data were collected during the period from 10 October 2000 to 30 March 2002. Measured soil respiration showed average values of 4.8 molCO2 m-2s-1 year round. Its seasonal differences varied from 2 to 8 molCO2 m-2s-1 (Q10 = 4.9) during the dry (April to August) and wet season, respectively, and was concurrent with soil temperature and moisture variability. The net ecosystem CO2 flux (NEE) variability is controlled by solar radiation,... |

| Abstract: The fish fauna of the Pelotas River, in the Upper Uruguay ecoregion of southern Brazil was inventoried. Samplings were performed quarterly between August 2013 and May 2014 at 14 sites in the Pelotas River and its tributaries, using gill nets of different mesh sizes, sein nets, cast nets and electrofishing. In total, 7,745 specimens were recorded, comprising 46 species, belonging to 13 families and five orders. Approximately 80% of the species belonged to the orders Characiformes and Siluriformes, as well as the families Characidae and Loricariidae, which included a greater number of species. Of the total species, 24% were endemic to the Upper Uruguay River, four were identified only at the genus level and none was considered non-native.... |

| Abstract: Data on the composition of local reptile assemblages in several Brazilian ecosystems can still be considered relatively restricted in scope in most cases. In this study, we conducted surveys in the Serra das Torres Natural Monument, located in the municipalities of Atílio Vivacqua, Muqui, and Mimoso do Sul, using the Rapid Assessments method (RAP) during 30 days in the rainy season of 2018. We sampled actively for approximately 1320 hours with a 6-10 person crew, supplemented by 720 hours of passive sampling (30 bucket-days) using pitfall traps with drift fences. We recorded 34 reptile species during our sampling method (2 amphisbaenid, 11 lizards, and 21 snakes) and an occasional encounter, after the end of sampling, that added a chelonian... |

| O objetivo desse estudo foi determinar a composição florística e a estrutura da vegetação lenhosa (incluindo monocotiledôneas e lianas) em cerrado rupestre na zona de transição Cerrado-Floresta Amazônica, no Parque do Bacaba, em Nova Xavantina, MT (14º 41' S e 52º 20' W) e compará-las com outros estudos de cerrado sentido restrito. Foram demarcadas aleatoriamente 10 parcelas de 20 × 50 m, nas quais foram medidos os indivíduos vivos e mortos em pé com diâmetro mínimo a 30 cm do solo (DAS) > 3 cm. O cerrado rupestre apresentou alta densidade (3.766 indivíduos vivos), riqueza florística (85 espécies, 67 gêneros e 34 famílias) e área basal (15,72 m²ha-1), e ainda elevado valor do índice de diversidade de espécies de Shannon-Wiener (H' = 3,47) e... |

| Although ascidians form a conspicuous part of sessile assemblages in the Caribbean, no specialized inventories have been developed in Venezuela, except for a list of 15 species reported from Margarita Island (1984). Here we present the results of a taxonomic workshop held in the Universidad de Oriente, Boca del Rio, Margarita Island during April 20-25 of 2009, sponsored by the NaGISA-Caribbean Sea program. La Restinga National park was surveyed and we found 29 species belonging to 19 genera and 10 families. The most abundant colonial species were Clavelina oblonga, Aplidium accarense, Polyclinum constellatum, Distaplia bermudensis, Symplegma rubra, S. brakenhielmi, Botrylloides nigrum and Ecteinascidia turbinata. Among the solitary ascidians Phallusia... |

| Poucos estudos foram realizados sobre a nidificação de tartarugas marinhas no litoral sul da Bahia, região que está passando por um processo rápido de ocupação turística que pode ameaçar ainda mais estas espécies. Por estes motivos, este estudo teve como objetivos identificar as espécies de tartarugas marinhas que desovam no local e descrever as principais características de suas ninhadas. Durante quatro temporadas reprodutivas, de 2004 a 2008, foram identificados e monitorados os ninhos encontrados nas praias localizadas entre Uruçuca e Itacaré no litoral sul da Bahia. As variáveis coletadas foram: tamanho de ninhada, duração da incubação, sucesso de eclosão e fases de mortalidade embrionária. Foi registrada uma média de 37 ± 6,2 ninhos por temporada, com... |

| Abstract: The forest along the coast of Bahia state, in northeastern Brazil, has been acknowledged as an area of endemism for several groups of organisms. The first study concerning endemic angiosperm species in this region, through which 395 taxa were registered, was conducted 15 years ago. However, this number is probably underrated. In this article, we present an updated checklist of angiosperm taxa in Bahia Coastal Forests (BCF) based on geographic distribution data available from the Brazilian Plant List (Flora do Brasil 2020). The records were checked in herbaria, recent taxonomic literature, and, when necessary, reviewed by experts. The final checklist consists of 547 taxa endemic to BCF, distributed in 69 families, with seven endemic genera:... |

| Abstract The capture of wild animals can provide important information on community structure, population dynamics, home range size, activity patterns, habitat use, denning, social behavior and health status. The objective of this study was to describe the method of capture with details on baits, injuries, non-target captures, anesthesia and costs, to evaluate its success as part of a health evaluation program of ocelots in a Brazilian Atlantic Forest Reserve. From a total of 1,011 trap-night effort in 86 days, we had 68 capture events composed of ocelots (22%, n=15) and non-target species (78%, n = 53). We captured 10 individual ocelots in 15 capture events, corresponding to 5.7 days to capture one ocelot. Capture efficiency was 14.8 ocelots/1,000... |

| A paisagem da região dos Campos de Cima da Serra, localizada no Norte do Rio Grande do Sul, encontra-se fragmentada e sua biodiversidade ameaçada devido ao impacto das atividades humanas. Esse trabalho investigou a fauna de borboletas em fragmentos de vegetação nativa (VN) e área antrópica (AA) de Floresta Ombrófila Mista nos municípios de Soledade e Mormaço. Em 108 horas-rede, foram registradas 1.181 borboletas distribuídas em 125 espécies, através de procura ativa com rede entomológica. VN registrou 72 espécies e 470 indivíduos, enquanto AA apresentou 89 e 711, respectivamente. Heliconius erato phyllis (Fabricius, 1775), Biblis hyperia nectanabis (Fruhstorfer, 1909) e Dryas iulia alcionea (Cramer, 1779) foram as três espécies mais abundantes no geral e... |
