The use of light sources in combination with mist nets was tested in order to verify their efficiency for capturing insectivorous bats. Using a ultraviolet light emitting luminous attractive and 10 mist nets mounted in rows, reached the conclusion that such methodology should be futher studied before being efficiently used in order to inventory the species of bats in a region

Plant-frugivore interactions are essential elements in ecosystem and their knowledge can becomes an important tool for the biodiversity maintenance. This study focused on analyzing the trophic structure of volant frugivore community and its implications for conservation. Bats and birds interactions events with plants were taken from three studies realized in Mata da Bica, a fragment of semideciduous seasonal forest in Botucatu- SP, and arranged in a matrix. A total of 40 interactions with 14% of connectance were found and only one dietary overlap between birds and bats was registrated. Carollia perspicillata (Phyllostomidae) bat showed the highest importance index (I=0,33) among the animals and Pereskia aculeata (Cactaceae) was the most important plant species (I=0,42). Birds and bats complemented each other in a possible dispersal process emphasizing different classes of animals’ role in an unique ecological process

Even though the presence of the female prostate has been reported in many species, including humans, bats and several rodents, it has many anatomical and histological variations. There is still plentiful discussion on the biological function of this organ. Many authors state that paraurethral ducts and glands are functional and homologous to the male prostate. The use of experimental models and a better knowledge of the female prostate gland in other species, can be useful to veterinary medicine as well as human medicine. Therefore the aim of this study is to check for the presence of this gland in female dogs of various breeds and age. For that purpose 25 urethras, from the bladder to the vulva, were collected, fixed in 10% neutral buffered formalin, routinely processed and sectioned into 4 slides of 4 µm, each with 40 µm gap between each set of 4 slides, using an automatic microtome and stained with Hematoxylin and Eosine (HE). The HE sections were evaluated for the presence of prostatic gland in the sample. Unstained tissue sections cut from paraffin blocks were marked with a polyclonal anti-PSA primary antibody. The prevalence of the gland was 32% (8/25). The structure of the paraurethral PSA-positive gland was acinar, organized in buds, with secretory epithelium varying from cubic to columnar; eccentric nuclei, with lose chromatin and a layer of basal cells, very similar to the male prostate were observed. In view of these characteristics, for the first time in the literature, was demonstrate that those glands. may be considered as female prostate in dogs, as they are in other vertebrates
