In recent years, there has been increasing interest in matrix-type influence on forest fragments. Terrestrial amphibians are good bioindicators for this kind of research because low vagility and high philopatry. This study compared richness, abundance, species composition terrestrial through pitfall traps two sets semideciduous seasonal fragments southeastern Brazil, according to the predominant surrounding matrix (sugar cane pasture). There were no differences but surrounded by sugar had...
Abstract The natural history of the lizard Enyalius perditus was studied from August 2005 to July 2006, at Parque Estadual Nova Baden, in municipality Lambari, State Minas Gerais, south-eastern Brazil. We found that E. may be considered a semi-arboreal species, like other species genus, sleeping on vegetation (slim branches or large leaves) night, possibly minimize predation. Females with enlarged follicles oviducal eggs were November January and juveniles recruited end dry season beginning...
Abstract Habitat loss and fragmentation are processes that may affect communities by changing species interactions. These changes occur because the strength of linkages between is not exclusively dependent on predator prey traits. Species interaction also depend spatial context in which they take place. We used structural equation modelling to evaluate effects these at patch-scale top-down bottom-up controls food webs Atlantic Forest. The model was composed multiple species, trophic guilds...
Abstract Small mammals seem to be affected by edge effects, hence understanding the local dynamics of these populations is important assess risks which they are exposed. The objective this study was compare population size, sex ratio and home range size rodent Akodon montensis (Cricetidae) between interior an Atlantic Forest fragment in dry (June-August) rainy (December-February) seasons. sampled using capture-mark-recapture methods a spool-and-line device used map movements. significantly...
ABSTRACT Some birds exhibit the behavior of nest parasitism, which involves laying their eggs in nests other species to be incubated and cared for by adoptive parents. Among all studies conducted on this subject, there is a gap regarding type parasites hosts. Therefore, using from Icteridae family, study aimed identify if tendency more closed less parasitized than open phylogenetic relationship between them. In context, we expected an ancestral condition nests, serving as evolutionary...
We report new records of three poorly-known species snakes in Minas Gerais: Bothrops lutzi (Miranda- Ribeiro, 1915), Psomophis joberti (Sauvage, 1884), and Trilepida brasiliensis (Laurent, 1949). The represent important filling gaps for all or even southern extensions the geographic distribution B. P. joberti. are located areas indicated as priority regions biodiversity conservation Cerrado. Maps known these also provided considering literature data from collections.
Pitfall traps are a sampling method broadly used in studies with small terrestrial vertebrates. In this paper, we compared the efficiency of modified pitfall anurans, squamates, and mammals. two forest fragments Seasonal Semi-deciduous Atlantic Forest, set up 26 arrays drift fences traps, composed four 30-liter buckets, each arranged ‘Y’ shape linked by fence 4 m length 0.5 height. We tested for effect an internal rim on border buckets comparing without capture efficiency. general, did not...
