Diversidade De Lepidoptera Em Um Fragmento Florestal Em Muzambinho, Minas Gerais

Abstract

RESUMOO monitoramento de populações de Lepidoptera fornece informações importantes para avaliar a dinâmica e as mudanças ecológicas nos ecossistemas. Neste trabalho avaliou-se e caracterizou-se a Lepidofauna da mata do IFSULDEMINAS -Campus Muzambinho -MG, estabelecendo um padrão para inúmeros fragmentos semelhantes na região. ABSTRACTThe monitoring Lepidoptera populations provides important information to assess the dynamics and ecological changes in ecosystems. In this work, it was evaluated and characterized the Lepidoptera fauna of forest fragment of the IFSULDEMINAS -Campus Muzambinho, MG state. Throughout 12 months, 590 Individuals of 69 species belonging to 10 families were captured. The most abundant family was Nymphalidae (73.56% of subjects). The most abundant species were Godartiana muscosa, Mechanitis lysimnia, Hermeuptychia sp and Mechanitis polymnia casabranca, which are bio-indicators of disturbed and/or urban environments. On the other hand, it was found rare species, such as Notascea brevispula. Different species were constant and others occurred in only a short period of the year. The diversity and abundance were higher in hot and rainy months. The diversity index Shannon-Wiener and Simpsom indicate a median diversity and equitability index point absence of dominance.

Communities of Lepidoptera along an elevational gradient in the Brazilian Atlantic Forest (Lepidoptera: Papilionoidea)

“…Nymphalidae was the richest and most abundant family (see Fig. 2), as also observed in previous surveys carried out in southern Minas Gerais (ANDRADE & TEIXEIRA, 2017;OLIVEIRA et al, 2018;VIEIRA et al, 2020), followed by Hesperiidae. Nymphalidae are found in almost all ecosystems (DEVRIES, 1987), have several food niches (BROWN JUNIOR et al, 1999), and can be efficiently captured by baited traps (FREITAS et al, 2003;UEHARA-PRADO et al, 2007;VIEIRA et al, 2020), which may explain its numerous captures.…”

“…Few butterfly inventories have been undertaken in the state, despite its great biodiversity and numerous Conservation Units. Some studies focused on Cerrado regions (SILVA et al 2007;PASETO et al, 2014;LUCENA et al, 2018;HENRIQUES et al, 2019), others on areas of transition from Caatinga to different phytophysionomies (GOZZI, 2012;NERY et al, 2014;BEIRÃO et al, 2017), and some on the Atlantic Forest (ANDRADE & TEIXEIRA, 2017;OLIVEIRA et al, 2018;VIEIRA et al, 2020). This study contributed to reducing the knowledge gap regarding butterfly diversity along elevational gradients in protected forest areas in Brazil, acting as a basis for the development of conservation strategies for butterfly communities in the Fernão Dias Environmental Protection Area.…”

Borboletas (Lepidoptera, Papilionoidea) em floresta estacional semidecidual do sul do estado de Minas Gerais, Brasil

“…A subespécie Mechanitis polymnia casabranca também foi registrada como a mais abundante nos trabalhos de Araújo et al (2015), em um Parque Ecológico de perímetro urbano, Andrade et al (2017) em um fragmento de Mata Atlântica. Essa espécie é considerada comum em florestas tropicais, fragmentos urbanos, ambientes perturbados e matas secundárias em formação (DEVRIES, 1987;BROWN JUNIOR, 1992;BROWN JUNIOR et al, 2003).…”

“…Furthermore, other factors commonly evidenced in urban green areas, such as the high homogenization of vegetation, the reduced supply of resources (Ruszczyk, 1987), and the high degree of isolation, directly affect lepidopteran communities reducing the number of species in these areas. Some authors, when carrying out surveys of lepidopterofauna in urban environments, forest fragments inserted in anthropogenic areas or close to urban regions, also recorded reduced numbers of species richness and abundance as described in Andrade & Teixeira (2017), Pereira & Soares (2020), Porath & Aranda, (2020) and Matias & Comeli (2020).…”
