Efeito do tamanho do fragmento florestal sobre as comunidades de Opiliones (Arachnida) em diferentes fitofisionomias no centro sul do estado de Minas Gerais

Abstract: A fragmentação dos ecossistemas terrestres é um dos fatores que mais afetam a qualidade do hábitat, o que impacta negativamente muitas espécies, entretanto há poucos estudos sobre esse efeito em Opiliones, aracnídeos que desempenham diferentes serviços ambientais. Esta pesquisa objetiva investigar o efeito do tamanho dos fragmentos sobre esses artrópodes em diferentes fitofisionomias de cerrado e mata atlântica. As coletas foram realizadas no período noturno, com 24 dias de trabalho de campo, entre outubro de … Show more

“…The abundance of Gonyleptidae species in the studied areas was expected, as they constitute the most diverse and abundant family in the Atlantic Forest in the southern and southeastern regions of Brazil (Kury, 2003), as observed in other studies in the same biome (Bragagnolo and Pinto-Da-Rocha, 2003;Nogueira et al, 2019;Resende et al, 2012aResende et al, , 2012bFerreira et al, 2019;Ferreira et al, 2020;Costa et al, 2020;Gomes et al, 2021;Andrade et al, 2022;Lima et al, 2022;Pádua et al, 2023). Until then, O. vegetus had been recorded only in the province of Misiones, Argentina (Soares and Soares, 1954;Ringuelet, 1959;Galiano and Maury, 1979;Kury, 2003) (Figure 3), its occurrence reported here may indicate a possible endemism of this species, since they are only found in areas of Semideciduous Forest and Mixed Ombrophilous Forest, which are phytophysiognomies of the Atlantic Forest, the biome with the highest endemism of harvestmen on the planet (Pinto-Da- , which suggests that this species may occur in other phytophysiognomies of the biome in Brazil, or may be endemic to these forest formations (Silva et al, 2015), since the low dispersal capacity of these arachnids (Mestre and Pinto-Da-Rocha, 2004) increase the endemism of the group, as already demonstrated for several species recorded in the Atlantic Forest (Pinto-Da- Silva et al, 2015).…”

“…The center of occurrence of these arachnids are tropical forests (Pinto-Da- , such as the Brazilian Atlantic Forest, which is home to the greatest richness on the planet, (Kury, 2023) and which concentrates most studies on these arthropods, particularly in the states of Minas Gerais, Rio de Janeiro and São Paulo (Bragagnolo and Pinto-Da-Rocha, 2003;Bragagnolo et al, 2007;Resende et al, 2012aResende et al, , 2012bCosta et al, 2020;Lima et al, 2022;Pádua et al, 2023), but there is little information for other Brazilian states, such as Paraná.…”

“…However, it is necessary to expand the information on Odonata communities, mainly in areas with potential for the creation of conservation units, such as Barroso, a municipality in the south-central region of the state (Oliveira, Henriques, Clemente, & Souza, 2021). Barroso is an important site for local biodiversity, not only of Odonata but also of other taxa (Souza, Pires, & Prezoto, 2014;Coelho, Gouvêa, Clemente, & Souza, 2022;Gouvêa, Clemente, Teófilo-Guedes, & Souza, 2021;Lima, Rubim, Pádua, & Souza, 2022). There is also a need for further inventories of dragonflies and damselflies, as the ones carried out so far indicate the existence of species exclusive to the region (Machado, 2015;.…”

“…No estado de Minas Gerais, há inventários em diferentes fitofisionomias (Ferreira et al, 2019;Costa et al, 2020;Ferreira et al, 2020;Pádua et al, 2022;Lima et al, 2022), mas não há informações para área de Mata Seca, mesmo em unidades de conservação (UCs), como o Parque Estadual da Mata Seca, considerado um dos mais importantes para proteção dessa formação florestal (Belém e Carvalho, 2013). Nessa perspectiva, o objetivo do estudo foi inventariar a fauna de opiliões no Parque Estadual da Mata Seca, MG.…”
