“…Based on the diet of the dolphins and on the seasonal variation of abundance of dominant prey types (especially fish from the Engraulidae Family), it has been hypothesized that the greater spatial requirements of the estuarine dolphins in the cold seasons were due to a lower abundance of food resources, whereas the opposite occurs in the summer (Daura-Jorge, 2003;Wedekin, 2003;Daura-Jorge et al, 2004). The negative relationship between the abundance of major food items and the size of the area used by individuals or groups has also been found in primates (Passamani and Rylands, 2000;Castro, 2003) and in one small cervid species (Tufto et al,996).…”

The use of space by the resident population of estuarine dolphins (Sotalia guianensis) in Norte Bay, southern Brazil was studied by boat surveys between 2000 and 2003. Data such as the geographical position and group size was collected at 5-minute intervals using focal-group sampling. The distribution and seasonal and daily group home-ranges were estimated using a GIS (Geographic Information System) environment. The dolphins did not use the area homogeneously, restricting their activities to a well-defined area located in the western part of the bay, while the use of the eastern part was not observed. A discrepancy between the Environment Protection Area of Anhatomirim, created especially to protect this population and the distribution of the dolphins was observed. Seasonal group home-range varied both qualitatively and quantitatively among the four consecutive seasons analyzed. The dolphins tended to use a larger area in cold seasons, when apparently the abundance of major prey items is lower. Core areas of intense use were identified, and also varied seasonally. These core areas may be regarded as critical habitats and require special legislation and control. The mean daily group home-range did not differ statistically among seasons. The present study corroborates a spatially strict residency pattern of the estuarine dolphin in highly productive coastal ecosystems.Keywords: distribution, home-range, seasonality, Cetacea, Norte Bay.Variação sazonal no uso espacial pelo boto-cinza, Sotalia guianensis (Cetacea; Delphinidae) no seu limite sul de distribuição ResumoA utilização espacial pela população residente de botos-cinza, Sotalia guianensis, na Baía Norte de Santa Catarina, Sul do Brasil, foi estudada por meio de saídas de barco realizadas entre 2000 e 2003. Dados como posição geográfica (GPS) e tamanho de grupo foram obtidos utilizando-se o método de grupo focal. A distribuição e a área de vida diária e sazonal do grupo foram estimadas por um SIG (Sistema de Informações Geográficas). O uso do espaço pelos botos foi heterogêneo, restringindo suas atividades a uma área bem definida, localizada na parte oeste da baía, enquanto a utilização do lado leste não foi observada. Observou-se uma discrepância entre a distribuição dos botos e a Área de Proteção Ambiental de Anhatomirim, criada especialmente para proteger esta população. A área de vida sazonal do grupo variou tanto qualitativamente como quantitativamente nas quatro estações do ano consecutivas estudadas. Os botos tenderam a utilizar uma área maior nas estações frias do ano, quando a abundância de suas presas potenciais parece ser menor. Identificaram-se áreas de maior concentração de indivíduos, que também tiveram variação sazonal. Estas áreas de concentração podem ser consideradas hábitats críticos e exigem controle e legislação especial. Não houve uma diferença sazonal significativa nas áreas de vida diária do grupo de botos nas diferentes estações do ano estudadas. Os resultados deste trabalho apontam para um padrão de residência espacialmente r...

“…For this reason, even considering that occasional large-scale individual movements and dispersal may occur, the group home-range concept was applied in the present study in the same way as it is applied in some primate social group studies (e.g. Stacey, 986;Passamani and Rylands, 2000;Castro, 2003).…”

“…The presence of mixed groups of the exotic species C. jacchus and C. penicillata is a potential threat to the local fauna and flora where they were introduced, since these species can act as predators of small vertebrates and invertebrates, besides damaging tree trunks and woody vines to feed on exudates (CoimbraFilho 1972;Silva and Cruz 1993;Rylands 1996;Digby and Barreto 1998;Castro et al 2000;Castro 2003). Another impact that can be caused by these exotic primates is the hybridization with other species of the genus, such as Callithrix aurita (É. Geoffroy, 1812) (Coimbra-Filho 1971;Coimbra-Filho et al 1993).…”

The Atlantic Forest is recognized as a global hotspot for having one of the highest rates of endemism and biodiversity. Its portion in the state of Rio de Janeiro is extremely fragmented and reduced. The present study seeks to get information on the non-volant mammals of RPPN Rio das Pedras in municipality of Mangaratiba, state of Rio de Janeiro. The rapid mammal's survey was accomplished by the use of pitfalls, live traps, transects and camera traps. We recorded 23 non-volant species that represent 13

Pesq. Vet. Bras. 33(Supl.1):75-84, dezembro 2013 75 RESUMO.-Para a análise e descrição comparativa da morfologia da língua e de suas papilas, bem como a distribuição destas, foram utilizados três animais de faixas etárias distintas (filhote, jovem, adulto), de duas espécies de primatas, Callithrix penicillata (sagui-de-tufo-preto) For the comparative analysis and description of the morphology of the tongue and taste buds as well as the distribution of these we have used three animals of different age groups (puppy, young adult), of two species of primate, Callithrix penicillata (black-tufted-ear-marmoset) and Alouatta caraya (black-howler-monkey), both being observed by scanning electron microscopy. The animals of the species Callithrix penicillata were from a commercial breeding of wild animals in Atibaia-SP and they had died of natural causes, and the specie Alouatta caraya were from the collection of Macroscopic Anatomy Laboratory of Faculty of Veterinary Medicine and Animal Science University of São Paulo (FMVZ-USP). With the material analyzed and the technique employed could be seen that the tongue of black-tufted-ear-marmosets and black-howler-monkeys had examined lingual papillae similar to those described for other primate species. The tongue has morphological differences, especially for some types of lingual papillae, at the expense of advancing age of the animals. Overall, we found four types of lingual papillae, which are: filiform, fungiform, vallate and litter. The tongues of the black-howler--monkey had characteristics of animals with herbivorous diets. Possessing this way with the filiform papillae varied formats (crown, spear, multifilament), according to the regions of the tongue, and also robust taste, especially in the lingual prominence. Since the tongues of the black-tufted-ear-marmosets owned features of omnivorous animals. With filiform-shaped crown, large amounts of fungiform papillae and foliate papillae developed. It was observed that the changes of tongue papillae that occur in animals after birth correlated with the change in the types of foods consumed. Being suspected then conclude that diets have direct relation to the morphological and structural of the lingual papillae now here in the animals analyzed.INDEX TERMS: Lingual papillae, scanning electron microscopy, Callithrix penicillata, Alouatta caraya.
