1. Analysis of ontogenetic variability of Bothrops insularis (Amaral, 1921) snake venom: adaptative implications for dietary items / Análise da variabilidade ontogenética do veneno de Bothrops insularis (Amaral, 1921)(Serpentes, Viperidae): implicações adaptativas aos itens alimentares
Mudanças ontogenéticas na dieta e na composição do veneno são características freqüentemente observadas em espécies do gênero Bothrops. A serpente Bothrops insularis é endêmica da Ilha da Queimada Grande, litoral Sul de São Paulo, cuja separação do continente ocorreu há aproximadamente 11 000 anos, após a última glaciação ao final do Pleis

2. Ecologia de populações de Lytocaryum hoehnei (Burret) Toledo (Arecaceae) na Reserva Florestal do Morro Grande, Cotia, SP
The present study has investigated aspects of the natural history and ecology of palm Lytocaryum hoehnei. The palms were accompanied in three sites at the Reserva Florestal do Morro Grande, Cotia, SP, approximately 4 km apart from each other, during 2000, 2001, and 2002. Four ontogenetic stages were identified: 1) seedling: individuals with entire leaves, 2)

4. Developmental Quantitative Genetics, Conditional Epigenetic Variability and Growth in Mice
Ontogenetic variation in the causal components of phenotypic variability and covariability is described for body weight and tail length in mice derived from a full 7 X 7 diallel cross. Age-related changes in additive, dominance, sex-linked and maternal variance and covariance between 14 and 70 days of age are described. Age-specific variance components at ti

5. Regional variability in secondary remodeling within long bone cortices of catarrhine primates: the influence of bone growth history
Secondary intracortical remodeling of bone varies considerably among and within vertebrate skeletons. Although prior research has shed important light on its biomechanical significance, factors accounting for this variability remain poorly understood. We examined regional patterning of secondary osteonal bone in an ontogenetic series of wild-collected primat

6. Encephalization and allometric trajectories in the genus Homo: Evidence from the Neandertal and modern lineages
The term “encephalization” is commonly used to describe an enlargement in brain size, considered as either absolute endocranial volumes or relative values in relation to body size. It is widely recognized that a considerable endocranial expansion occurred throughout the evolution of the genus Homo. This article aims to evaluate whether this phenomenon wa
