Behavior and foraging technique of the Ingram's squirrel Guerlinguetus ingrami (Sciuridae: Rodentia) in an Araucaria moist forest fragment

This work describes the foraging techniques, body positions and behavior of free-ranging Ingram's squirrel Guerlinguetus ingrami Thomas, 1901 in a region of the Araucaria moist forest, in the Atlantic Forest of southern Brazil. The animals were observed using the all occurrence sampling method with the aid of binoculars and a digital camcorder. All behaviors were described in diagrams and an ethogram. We recorded five basic body positions, 24 behaviors, two food choices, and three feeding strategies utilized to open fruits of Syagrus romanzoffiana (Cham.), the main food source of Ingram's squirrels. We also observed a variance in the animals' stance, which is possibly influenced by predation risk, and discuss the causes of some behaviors.

Deslocamento de caráter em hilídeos neotropicais (anura: hylidae)

The interspecific competition tends to favor the selection of divergent phenotypes minimizing the effect of this interaction. This process is termed character displacement and it is considered one of the main mechanisms promoting adaptive diversification. Brazil has the greatest diversity of amphibians on the planet and despite this great diversity; the role of character displacement in the process of Brazilian amphibian fauna diversification has not been studied. In the present study we tested the hypothesis of character displacement in four congeneric species pairs of frogs from the family Hylidae, occurring in the Atlantic Forest and Cerrado. We find evidence of character displacement for two pairs and parallel evolution for the remaining. Interestingly, the trend of character displacement was in species whose range covers less stable habitats. Since this is a pioneering study with neotropical hylid, we discussed issues considered relevant to elucidate mechanisms related to the maintenance of diversity

Parque Estadual da Serra do Mar, Núcleo Santa Virginia: uma análise paisagística comparativa do período de 1989 até o presente

The Atlantic Forest is considered the fifth most important hotspot of the world, for its high endemism and biodiversity. The Serra do Mar State Park (SMSP) is the biggest area of integral protection in Brazilian coast, having the largest continuous remnant area of Atlantic Forest. Its creation aims to protect the Atlantic Forest remnants and regeneration of degraded areas. The present work develops in the administrative center Núcleo Santa Virgínia, created on May 2, 1989 and aims a comparative analysis and environmental interpretation regarding the evolution of the landscape its creation until the present days, using geoprocessing techniques. For a better understanding of some definitions, a literature review is presented about the current scenario of conservation units, concepts of landscape, landscape ecology, landscape dynamics and the importance of the geoprocessing for landscape analysis. It was elaborated two thematic charts of use and occupation land of Núcleo Santa Virgínia (1989 and 2014) and quantified for each type of use for later comparison

Aplicação dos conceitos da ecologia de paisagem para a definição de hotspots de conservação e de conectividade entre o Complexo Cantareira e Nazaré Paulista

The Atlantic Forest biome, reduced to 12% of its original coverage, holds a significant portion of brazilian biodiversity, with high levels of endemism. Among the few remaining areas of the Atlantic, there is the region between the Complex of Cantareira and the municipality of Nazaré Paulista, which will be the object of study of this work. Using the concepts of Landscape Ecology, and analysis of thematic maps, this study aims to characterize the region in a ecologically scaled perspective, identifying two types of hotspots: i) for conservation and ii) for maintain habitat connectivity. Concepts of Landscape Ecology as landscape structure, patches, matrix, corridors (structural and functional) and connectivity, as well as their effects on local biodiversity was adopted and applied in the study region. We also analyzed the effects of roads, hydrographic system, Permanent Protection Areas (PPAs), and Conservation Units for flora and fauna maintenance at regional scale. This allowed us to define strategies and priority areas for the conservation and restoration of forest fragments of Atlantic Forest remnants within the study region. This study generated relevant knowledge for a better planning the region in order to create best conditions for the maintenance of regional biodiversity, and consequently, allowing to improve the quality of life for local population
