Frugivoria de morcegos (Mammalia, Chiroptera) em Cecropia pachystachya (Urticaceae) e seus efeitos na germinação das sementes
Provedor de dados: Papéis Avulsos de Zoologia
Autores: Sato,Therys Midori; Passos,Fernando de Camargo; Nogueira,Antonio Carlos.
Os morcegos frugívoros são componentes fundamentais na manutenção e regeneração de florestas tropicais, pois ao se alimentarem, promovem a mobilidade das sementes dos frutos em que se alimentaram. Muito se discute sobre os efeitos da passagem das sementes no trato digestivo dos morcegos sobre a taxa e velocidade de germinação. O objetivo deste trabalho foi examinar a dieta das espécies de morcegos frugívoros na Estação Experimental de Itirapina para descobrir quais utilizam significativamente os frutos de Cecropia pachystachya. Foi testada a importância dos quirópteros na dispersão e germinação desta espécie de planta. Para isso, os morcegos foram capturados no período de agosto de 2005 a julho de 2006, suas fezes foram recolhidas e as sementes de C....

Dieta de um grupo de mico-leão-preto, Leontopithecus chrysopygus (Mikan) (Mammalia, Callitrichidae), na Estação Ecológica dos Caetetus, São Paulo
Provedor de dados: Zoologia
Autores: Passos,Fernando de Camargo.
In this study carried out in the Caetetus Ecological Station, Sao Paulo, southeastern Brazil, a wild group of black lion tamarins was accompanied during 1989 to 1991, to analyse the dietary habits of the species. The scan sampling method was used to gather data. A total of 961 behaviors were recorded, of which feeding occupied 23.3% of the time involved in the behaviors. The major dietary components observed in the black lion tamarins were fruits, tree exudates and animal preys (67.9%, 22.8% and 8.9% respectively). Fruits varied monthly from 47.4 to 97.1 %, being consumed more during the rainy season, while tree exudates varied from 0 to 54.7%, and were consumed mainly during the dry season. The animal prey accounted for 0 to 15.8% of the diet. The most...

Foraging behavior and microhabitats used by black lion tamarins, Leontopithecus chrysopygus (Mikan) (Primates, Callitrichidae)
Provedor de dados: Zoologia
Autores: Passos,Fernando de Camargo; Keuroghlian,Alexine.
Foraging in the Black Lion Tamarin (L. chrysopygus Mikan, 1823) was observed in the Caetetus Ecological Station, São Paulo, southeastern Brazil, during 83 days between November 1988 to October 1990. These tamarins use manipulative, specific-site foraging behavior. When searching for animal prey items, they examine a variety of microhabitats (dry palm leaves, twigs, under loose bark, in tree cavities). These microhabitats were spatially dispersed among different forest macrohabitats such as swamp forests and dry forested areas. These data indicated that the prey foraging behavior of L. chrysopygus was quite variable, and they used a wide variety of microhabitats, different of the other lion tamarin species.

Long-distance movement by a great fruit-eating bat, Artibeus lituratus (Olfers, 1818), in southeastern Brazil (Chiroptera, Phyllostomidae): evidence for migration in Neotropical bats?
Provedor de dados: Biota Neotropica
Autores: Arnone,Ives Simões; Trajano,Eleonora; Pulchério-Leite,Atenisi; Passos,Fernando de Camargo.
In Brazil, bat migrations have been inferred based on seasonal variations in bat abundances observed for several species, probably as a result of variations in temperature and food availability. However, direct evidence of individual medium to long distance (&gt; 10 km) movements, based on marked specimens, is restricted to large frugivorous bats, genus Artibeus (Phyllostomidae). We report the longest bat movement recorded in Brazil, along 113 km in a straight line, difference in altitude of 738 m, from a mixed Araucaria forest in Curitiba, PR, to the Atlantic Forest, Alto Ribeira, SP, by a female Artibeus lituratus (Olfers, 1818), over a period of 14 months. This data is consistent with the occurrence of migratory movements in Neotropical bats, such as...

Primeiro registro de Myotis albescens (É. Geoffroy, 1806) (Chiroptera, Vespertilionidae) para o Estado do Paraná, Brasil
Provedor de dados: Biota Neotropica
Autores: Miranda,João Marcelo Deliberador; Pulchério-Leite,Atenisi; Bernardi,Itiberê Piaia; Passos,Fernando de Camargo.
Este é o primeiro registro do morcego vespertilionídeo Myotis albescens (É. Geoffroy, 1806) para o Estado do Paraná. Um indivíduo de Myotis albescens foi registrado na Ilha Mutum, Município de Porto Rico (22° 46' 20" S e 53° 16' 01" W). Esse registro preenche parte de uma lacuna na distribuição de M. albescens, além de contribuir com o conhecimento da mastofauna paranaense.

Home-range and space use by Didelphis albiventris (Lund 1840) (Marsupialia, Didelphidae) in Mutum Island, Paraná river, Brazil
Provedor de dados: Biota Neotropica
Autores: Sanches,Vítor Quadros Altomare; Gomes,Mariuciy Menezes de Arruda; Passos,Fernando de Camargo; Graciolli,Gustavo; Ribas,Augusto Cesar de Aquino.
Home-range is the area used by an animal in its daily activities. Home-range studies provide data on species mating systems and territorial behavior. Our main goal was to estimate the Didelphis albiventris (Lund 1840) home-range in Mutum Island, Paraná River, Brazil. The study was carried out in 2008 from March to October on a 19.20 ha grid. The island is part of the Parana River Islands and Floodlands Federal Environmental Protection Area, with vegetation composed by Alluvial Semideciduous Seasonal Forest in a region of Subtropical Wet climate. The sampling effort was 3,360 traps-night resulting in 152 Didelphis albiventris (Lund 1840) captures. Forty-one Didelphis albiventris (Lund 1840) individuals were captured in 42 capture stations, composed by a...
