Vertical stratification on a small scale: the distribution of fruit-feeding butterflies in a semi-deciduous Atlantic forest in Brazil Stud. Neotropical Fauna Environ. (IF 0.943) Pub Date : 2020-02-23 Poliana Felix Araujo; André Victor Lucci Freitas; Gleice Ane de Souza Gonçalves; Danilo Bandini Ribeiro
Recently, the availability of cheap and effective survey methods increased the number of forest canopy studies. Several studies have described butterfly communities in the upper forest stratum. However, these studies were all conducted in tall forests (20–60 m canopy height). Here we aim to assess the stratification of fruit-feeding butterfly species in two vertical strata of a semi-deciduous seasonal

Breeding biology of the Creamy-bellied Thrush (Turdus amaurochalinus) in southeast Brazil Stud. Neotropical Fauna Environ. (IF 0.943) Pub Date : 2020-02-18 Augusto Florisvaldo Batisteli; Mariana Yamamoto Costiuc; Isadora Zavan Santieff; Rosane Oliveira Costa; Hugo Sarmento; Marco Aurélio Pizo
ABSTRACT The description of life-history traits is a prerequisite to understand the complex patterns of bird biodiversity. However, most of the highly diverse Neotropical avifauna still lack basic information on their reproductive behavior. Here, we describe the breeding biology of the Creamy-bellied Thrush (Turdus amaurochalinus) in a periurban area of southeast Brazil. We found 67 nests between early

Cavity-nesting bee communities in areas with different levels of vegetation disturbance Stud. Neotropical Fauna Environ. (IF 0.943) Pub Date : 2020-01-07 Anete P. Lourenço; Ana Paula M. Santos; Hélio H. Checon; Mayra R. Costa; Sebastião L. Assis Júnior
The reasons for the decline of bee diversity and abundance include the destruction and loss of natural habitats. Protected areas are created for biodiversity conservation, but these areas vary strongly in their level of vegetation disturbance. Using trap-nests, we assessed changes in solitary bee abundance, richness, and composition in areas ranging from naturally conserved to degraded. Solitary bees
