Revista Brasileira de Zoologia 21 (4): 871-876, dezembro 2004Os mamíferos constituem um dos grupos de vertebrados que apresentam variações em seu regime alimentar (POUGH et al. 1993). A partir do estudo da dieta desses animais, outras informações podem ser obtidas, como a interação planta-animal.A evolução das interações permitiu que o mutualismo entre plantas e animais frugívoros atingisse seu clímax nas florestas tropicais, onde aves e mamíferos contribuem com a dispersão de sementes de 50 a 90% das espécies arbóreas e

ABSTRACT. Diversity ofbats (Chiroptera, Mammalia) in forest fragments. The bay of the Tibagi ri ver, a place which goes tlU'ough quick envirorunental alterations, has three forest fragments: the " Floresta Nacional do [rati" (3.572 ha), the "Reserva Biológica da Klabin" (1 1.116 ha) and the "Parq ue Estadual Mata dos Godoy" (680 halo Here, Myolis ruber (E. Geoffroy, 1806) and Chiroderma doriae Thomas, 1891 can be found, these are threatened bats, and three species, Pygode/'lIla bilabiallllll (Wagner, 1843), Myolis levis (I. Geoffroy, 1824) and Rogheessa lumida H. Allen, 1866, which are presumably threatened. Using the same effOlt of capture in the three places, it was stated that the "Floresta Nacional do Irati " with low vegetation diversity, showed nine spec ies of bats. The "Pa rque Estadual Mata dos Godoy", although it 's five times smaller, !lfteen species. We came to the conclusion that a big reserve, without good conditions would house a lower number ofspecies. A small reselve with adequate resources and great vegetation diversity presents a higher number ofniches, housing a higher number of spec ies. KEY WORDS. Chiroptera, bats, diversity, forest fragments As unidades de conservação protegem valores ambientais representativos, por isso teriam que assegurar o bem estar das comunidades animais e vegetais, melhorando as condições do ambiente na região onde estão locali zadas, sem inibir o progresso econôm ico das local idades que as abrigam. Deveriam também assegurar uma proteção legal, mantendo ao máximo os valores naturais que justifiquem sua preservação, e ainda, ser uma unidade biogeográfica representativa com "habitats" favoráveis que preservem a flora e a fauna local.Poderiam atender, como centros de educação e pesquisa, visando otimizar a convivência animal -floresta, em situações que preservem os "habitats" e evitem o risco de extinguir espécies, conseqüentemente proteger os materiais genéticos.Todavia, essas regiões estão sofrendo alterações ambientais rápidas e significativas, devido ao seu potencial agropecuário, demandando cada vez mais apro-

ABSTRACT. TOOL USE lN CEBUS APELLA (LINNAEUS) (PRIMATE, CEBIDAE) TO GEl COLEOPTERA LARVAE mAT PARASITE SEEDS OF SYAGRUS ROMANZOFFIANUM (CiIAM.) GLASSM. (ARECACEAE). This paper reports the behavior ofthe black capped capuchin monkey, Cebus apella, using tools to break seeds of Syagrus romanzojJianum in search of coleoptera larvae that live inside. The study area was the Parque Municipal Al1hur Thomas (85,47 ha) located in the city ofLondrina, Paraná state. ln one year ofsludy, using lhe ad /ibilum method, the monkeys were observed using rocks pretty much in lhe same way as ifthey were hammer and anvil. Individuais ofboth sexes including adulls, subadults andjuveniles with more than!wo years ofage, were involved in such activity. The behavior ofthe animaIs consisted oflhey place the seeds on a large rock in the ground, and using a smaller rock which was hold among the hands, lhe seeds were beaten repeatedly until breaking. Then they ate the larvae and/orendospenn. The use oftools is thought to have brought benefits to the animais by allowing the access to a SOut'ce offood lhat would not norl11ally be used.

Mortality from collision with vehicles is the most visible impact of road traffic on wildlife. Mortality due to roads (hereafter road-kill) can affect the dynamic of populations of many species and can, therefore, increase the risk of local decline or extinction. This is especially true in Brazil, where plans for road network upgrading and expansion overlaps biodiversity hotspot areas, which are of high importance for global conservation. Researchers, conservationists and road planners face the challenge to define a national strategy for road mitigation and wildlife conservation. The main goal of this dataset is a compilation of geo-referenced road-kill data from published and unpublished road surveys. This is the first Data Paper in the BRAZIL series (see ATLANTIC, NEOTROPICAL, and BRAZIL collections of Data Papers published in Ecology), which aims make public road-kill data for species in the Brazilian Regions. The dataset encompasses road-kill records from 45 personal communications and 26 studies published in peer-reviewed journals, theses and reports. The road-kill dataset comprises 21,512 records, 83% of which are identified to the species level (n = 450 species). The dataset includes records of 31 amphibian species, 90 reptile species, 229 bird species, and 99 mammal species. One species is classified as Endangered, eight as Vulnerable and twelve as Near Threatened. The species with the highest number of records are: Didelphis albiventris (n = 1,549), Volatinia jacarina (n = 1,238), Cerdocyon thous (n = 1,135), Helicops infrataeniatus (n = 802), and Rhinella icterica (n = 692). Most of the records came from southern Brazil. However, observations of the road-kill incidence for non-Least Concern species are more spread across the country. This dataset can be used to identify which taxa seems to be vulnerable to traffic, analyze temporal and spatial patterns of road-kill at local, regional and national scales and also used to understand the effects of road-kill on population persistence. It may also contribute to studies that aims to understand the influence of landscape and environmental influences on road-kills, improve our knowledge on road-related strategies on biodiversity conservation and be used as complementary information on large-scale and macroecological studies. No copyright or proprietary restrictions are associated with the use of this data set other than citation of this Data Paper.

ABSTRACT. Bats trom Monte Alegre Farm, Telêmaco Borba, Paraná (Mammalia, Chiroptera). A survey of bats species from Monte Alegre Farm is presented. One hundred and two bats of 14 species belonging to Phyllostomidae and Vespertilionidae were colected. Remarks about reproduction and feeding habits are included. KEY WORDS. Bats, reproduction, feeding habits A área florestal da Klabin Fabricadora de Papel e Celulose S. A., empresa localizada no estado do Paraná, foi criada em 1941, com a finalidade de suprir as necessidades de madeira da fábrica instalada em Monte Alegre, município de Telêmaco Borba. Além de explorar o "pinheiro do Paraná" [Arauearia angustifolia (Bert.) Kuntze] nativo e abundante na região, a empresa empenhou-se, desde o início, na pesquisa de espécies que pudessem se aclimatar na área, bem como preocupou-se com a biodiversidade local. Para tanto, implantou o Parque Ecológico da Fazenda Monte Alegre, visando a realização de estudos científicos nos diversos ecossistemas presentes na região, com especial ênfase no que se refere à fauna e à flora nativas.Considerando a inexistência de informações sobre os morcegos do Parque, trabalhos de campo foram conduzidos na região, possibilitando um levantamento preliminar das espécies de quirópteros que ocorrem na área, bem como a obtenção de dados bionômicos a respeito. MA TERIAL E MÉTODOS Área de estudoA Fazenda Monte Alegre conta com área de 126.373,10 hectares e suas coordenadas geográficas são 24°12'42"S e 50 0 33'26''W. Sua altitude média é de 885m e o clima, segundo a classificação de Kõppen, enquadra-se como subtropical, com a temperatura média do mês mais frio de 16,3°C e temperatura média do mês mais quente 23,2°C. A média anual de precipitação pluviométrica é de 1.478mm.

Migration is defined as a seasonal and cyclic population movement observed in all animal classes and studied mainly in vertebrates. A considerable part of the knowledge on migration comes from birds, for which migration is an important aspect of their biology. In the case of bats, females usually migrate larger distances than males in some species. The present study analyzes the seasonal occurrence of Pygoderma bilabiatum (Wagner, 1843) at different elevations, in order to test for a pattern that evidences migration, using data from the states of Espírito Santo, Minas Gerais, Rio de Janeiro, São Paulo, Paraná, Santa Catarina, and Rio Grande do Sul, Brazil. A total of 529 specimens of P. bilabiatum were captured. Pygoderma bilabiatum seems to be more frequent at intermediate and high elevations (over 80% of all captures were made above 250 m a.s.l.) and at latitudes above 22°S, where rainfall is high (over 1,500 mm) and temperatures are mild (16-23°C). Sex ratio varied with elevation; it was skewed towards males at lower elevations (N = 9, r² = 0.60, F = 12.311, p = 0.008, Sex ratio = 0.0004*elevation + 0.976), though females predominated at all altitudinal bands and in all states analyzed
