A escape of the fiddler crab Uca rapax (Smith, 1870), in the state of Minas Gerais is reported for the first time. This record was made more than 200 km away from its original habitat, a mangrove area in the state of Rio de Janeiro. The species has been introduced in ponds in the study area, located in the largest ornamental pisciculture/aquaculture center of Brazil. Male individuals of U. rapax were observed engaged in territorial and courtship displays around their burrows. Despite this, there is no well-established population of the species in the area, due to the physiological dependence of the larvae on brackish water. © 2007 Instituto de Ciências Biológicas - UFMG.

Natural history studies aim to know where the organisms live, what they do, and their relationships within the environment, including the other organisms. The anurans, among other vertebrates, exhibits the greatest variety of reproductive modes as well as a high complexity of social organization, that may enable a lot of naturalist studies. Anurans modes of organization are direct related to parental care, vocalization of chorus organization, and with males territoriality. In general, the social organization is influenced by species reproductive pattern. This study aim to get information about the natural history of Hypsiboas albopunctatus (perereca-cabrinha) a species of the family Hylidae, on the region of Rio Claro Municipality, São Paulo State, Brazil. The major aspects discussed were: seasonality, spatial distribution, acoustic and visual communication, reproductive mode, reproductive site, abiotic factors influences, territoriality, courtship behaviour, satellite male behavior, embrace and defensive behavior. To obtain this data, nocturnal field excursions were realized monthly. Two sites of Rio Claro county where chosen as studies sites, the sítio Cantaclaro (22o19’36’’S; 47o42’57’’O), on the District of Itapé and Floresta Estadual Edmundo Navarro de Andrade (FEENA) (22o24’58’’S; 47o31’26’’O).
