Riqueza e composição de Arctiinae (Lepidoptera, Erebidae) em cinco Unidades de Conservação do Cerrado

Abstract

ABSTRACT. Richness and composition of Arctiinae (Lepidoptera, Erebidae) in five Conservation Units in the Cerrado biome. The Cerrado biome contains about 50% of the Brazilian Arctiinae moths. However, northern region of the Cerrado is under-sampled for these insects, where there are more preserved areas. Here, we described the richness, composition, abundance, and beta diversity of Arctiinae in different vegetation types in five Protected Areas in the Cerrado northeast. We found 83 species, almost 78% of them occurred in one Protected Area. Less preserved localities had higher species richness. This result can be explained as a response to frequent intermediate disturbances in the landscape of these places. Forested areas were richer in species, supporting the environmental heterogeneity hypothesis. Compositional similarity was low among protected areas and among vegetation types. More complete inventories are required to assess which factors are influencing species richness and composition patterns of Arctiinae moths in these localities and thus guide future conservation actions. KEYWORDS. Protected Areas, inventories, moths.RESUMO. Cerca de 50% da diversidade de mariposas Arctiinae do Brasil está no Cerrado. Contudo, a fauna desses insetos é extremamente subamostrada na região norte do bioma, onde localizam-se as áreas de vegetação mais preservadas. Diante disso, este trabalho teve como objetivos descrever a riqueza, abundância, composição e diversidade beta de Arctiinae em diferentes fitofisionomias de cinco Unidades de Conservação localizadas no nordeste do Cerrado. Foram amostradas 83 espécies, das quais quase 78% ocorreram em apenas uma Unidade de Conservação. As localidades com menor grau de preservação apresentaram maior riqueza de espécies, o que pode ser explicado como uma resposta a distúrbios intermediários na paisagem destes locais. As fitofisionomias florestais foram mais ricas em espécies, corroborando a hipótese da heterogeneidade ambiental. De maneira geral, a similaridade da fauna foi baixa tanto entre as Unidades de Conservação quanto entre as fitofisionomias. Inventários mais completos precisam ser feitos a fim de avaliarmos que fatores estão influenciando os padrões de riqueza e composição de Arctiinae nestas localidades de Cerrado e, assim, subsidiar futuras ações de conservação. PALAVRAS-CHAVE.Áreas protegidas, inventários, mariposas.

Changes in Species Richness and Composition of Tiger Moths (Lepidoptera: Erebidae: Arctiinae) among Three Neotropical Ecoregions

“…Our results ( Fig 4 , Permutest and Pearson correlation) show that the climatic seasonality becomes an important factor in the distribution of tiger moths at higher latitudes. Nonetheless, some authors suggest that vegetation types also influence significantly the assemblages of tiger moths [ 17 , 19 , 27 , 28 , 51 , 52 , 55 ]. Although we could not study the vegetation type, the resulting NMDS ordination indirectly reflected strong vegetation units that encompass plant communities from subtropical rainforest in Paraná, montane forest in Yungas to dry forest in Chaco Serrano.…”

Arctiinae (Lepidoptera: Erebidae) in the state of Rio de Janeiro, Brazil

“…In a recent study, Vincent & Laguerre (2014) published a catalog of the Neotropical Arctiini (except Ctenuchina and Euchromiina) in which presents an updated list of neotropical tiger moths, with 2,404 species of Arctiini. In Brazil, there are several studies about tiger moths, in different biomas like Savanas (Ferro & Diniz 2007, Ferro& Diniz 2010, Moreno et al 2015, the Amazon Forest (Teston & Delfina 2010, Delfina & Teston 2013, Teston & Correa, 2015 and even in the Atlantic Forest (Ferro & Teston 2009, Ferro & Melo 2011, Ferro & Romanowski, 2012, Zenker et al 2015. In general, these works address the richness, diversity and species composition of Arctiinae in certain areas, but there are few studies that compile lists of species for Brazilian states.…”
