Levantamento populacional do cervo-do-pantanal Blastocerus dichotomus (Mammalia, Cervidae) no Parque Nacional de Ilha Grande e entorno: implicações para a conservação

We conducted an aerial survey of the marsh deer population Blastocerus dichotomus (Illiger, 1815) in the Ilha Grande National Park and its surroundings, on the border between the states of Parana and Mato Grosso do Sul, Brazil, during the dry season. We used the double-counting technique, resulting in a population estimate of 1079 ± 207 marsh deers in a sampled area of 1081 km2, corresponding to an estimated density of 0.998 ± 0.192 ind/km2. The population was mostly concentrated inside the park, but also occupied altered wetlands outside its limits. The results should be used to support population management and conservation measures at the national park and its surroundings, due to the enormous anthropogenic pressure upon the marsh deer population in the region.

First record of Juliomys ossitenuis Costa, Pavan, Leite & Fagundes, 2007 (Rodentia, Sigmodontinae) in Paraná state, southern Brazil

Juliomys ossitenuis was previously known from the Atlantic Forest of southeastern Brazil, where it occurs in Dense Ombrophilous Forest. The record of the species in Floresta Nacional de Pirai do Sul, in Parana state, confirmed by morphological and cytogenetic analyses, extends its distribution about 200 km southwards. This is the first record of the species in the state and in an area of Mixed Ombrophilous Forest (Araucaria Forest).

Range extension for Drymoreomys albimaculatus Percequillo, Weksler & Costa, 2011 (Mammalia, Rodentia, Cricetidae) in Mixed Ombrophilous Forest of southern Brazil with the first occurrence from the state of Paraná

Drymoreomys albimaculatus is a recently-described rodent and an Atlantic Forest endemic. It is rare and has a poorly defined geographic distribution. This article presents the first record of D. albimaculatus from Paraná state, Brazil and expands the known range of this species into northeastern Santa Catarina state. Both records are from Mixed Ombrophilous Forest and Semideciduous Seasonal Forest types.

Identidade, riqueza e abundãncia de pequenos mamíferos (Rodentia e Didelphimorphia) de área de Floresta com Araucária no estado do Paraná, Brasil

Roedores e Marsupiais sao componentes importantes da fauna na regiao Neotropical. Estudos sobre a riqueza e abundância destes animais sao raros na Floresta Ombrofila Mista (FOM) e aqui apresentamos um inventario conduzido na Floresta Nacional de Pirai do Sul. Esta area possui uma area aproximada de 150 ha, cercada por pastos e plantacoes de Pinus. A amostragem foi feita atraves de armadilhas de queda, Sherman e Tomahawk, dispostas nos principais tipos de vegetacao encontrados. Pelo menos um casal de cada especie foi coletado. Como resultado, durante 5.892 armadilhas.noite nos obtivemos um total de 1.049 capturas, representando 17 especies: Akodon montensis, Bibimys labiosus, Brucepattersonius iheringi, Cryptonanus sp., Didelphis albiventris, D. aurita, Gracilinanus microtarsus, Monodelphis americana, M. scalops, Myocastor coypus, Nectomys squamipes, Oligoryzomys nigripes, Oxymycterus judex, O. nasutus, Sooretamys angouya e Thaptomys nigrita. Capturas por armadilhas de queda representaram 67% do total, e oito especies foram registradas exclusivamente por este metodo. Akodon montensis, O. nigripes e T. nigrita foram as especies mais abundantes.
