Body masses and measurements of birds from southern Atlantic Forest, Brazil Zoologia
Reinert,Bianca L; Pinto,Júlio C; Bornschein,Marcos R; Pichorim,Mauro; Marini,Miguel Â.
Five hundred and eigh body masses of 74 forest birds, and measurements of wing, tail, tarsus and beak of 14 poorly known species mist-netted at two sites in the Atlantic Forest of eastern Paraná State, southern Brazil, are presented.

Nest and egg description of threatened Herpsilochmus spp. from coastal forest habitats in Rio Grande do Norte, Brazil (Aves: Thamnophilidae) Zoologia
Silva,Marcelo da; Pichorim,Mauro; Cardoso,Márcio Z..
We provide description of eggs and nest structure for two Brazilian antwrens, including the IUCN "vulnerable" species, H. pectoralis Sclater, 1857, and the BirdLife International "near-threatened", H. sellowi Whitney & Pacheco, 2000. Our observations derive from a larger study on Herpsilochmus Cabanis, 1847 distribution in coastal forest fragments in the northern range limit of the Brazilian Atlantic rainforest. Both species nested in relatively open forest. The nest of H. sellowi was built with fungal hyphae, a trait common among some birds. Both eggs were moderately beige with brown spots. Most of the information on Brazilian antwren nesting comes from species that do not occur in the Atlantic rainforest. This is the first account for nest...

The influence of clutch and brood sizes on nesting success of the biscutate swift, Streptoprocne biscutata (Aves: Apodidae) Rev. Bras. Zool.
Pichorim,Mauro.
The nesting success of three colonies of Streptoprocne biscutata (Sclater, 1866), and the influence of clutch and brood size on nesting success of species were studied. Overall, apparent nesting success was 58% and Mayfield nesting success was 53%. Nest survival during incubation (64%) was lower than during the nestling period (83%). During incubation, clutches were lost to rain, desertion, predation, egg ejection, egg damage, and egg disappearance. During the nestling period, losses occurred due to offspring disappearance, nestling death by starvation, predation and falling. During both incubation and nestling periods, predation was low, while egg ejections and nestling starvation were the main causes of nest failure. Nest survival during incubation was...

Wide-range genetic connectivity of Coney, Cephalopholis fulva (Epinephelidae), through oceanic islands and continental Brazilian coast Anais da ABC (AABC)
Souza,Allyson S. de; Dias Júnior,Eurico A.; Galetti Jr,Pedro M.; Machado,Erik G.; Pichorim,Mauro; Molina,Wagner F..
The Epinephelidae form a group of species of high biological and economical interests. It´s phylogeographic patterns are not well known especially the distributed populations in the western region of the Atlantic Ocean. Among the representatives is a small species called Cephalopholis fulva, Coney, which presents a wide geographical distribution, polychromia, hermaphroditism and is quickly becoming a large target for the exploration of commercial fishing. The genetic and historical demography were obtained through the partial sequence analysis of Control Region from six locations on the coastline of Brazil from the northeast coast to the southwest coast, including the oceanic islands of Rocas Atoll and Fernando de Noronha Archipelago. The analyzed samples...

Wild pig (Sus scrofa L.) occupancy patterns in the Brazilian Atlantic forest Biota Neotropica
Hegel,Carla Grasiele Zanin; Santos,Luane Reis dos; Pichorim,Mauro; Marini,Miguel Ângelo.
Abstract: Despite the great impacts of invasive wild pig (Sus scrofa) to natural ecosystems, habitat use by this species in the neotropics remains poorly studied. Here, we investigated the effects of local habitat and landscape covariates (vegetation types, running watercourses and roads) on occupancy patterns of wild pig in the Atlantic Forest of southern Brazil. We used single season occupancy modeling to estimate detection (p) and occupancy (ψ) probabilities, using 8-day camera-trap monitoring of 100 sampled sites. The cameras detected wild pig in 64 sites (naïve occupancy = 64 %). The four best models explained 72.7 % of the occupancy patterns, and the top model (with "water" variable) had a weight of 28.5 %. Even though none of the tested variables...
