Why do males and females frequently differ so markedly in body size and morphology? Sex,
Size, and Gender Roles is the first book to investigate the genetic, developmental, and …

Abstract The Guiana Shield (GS) is one of the most pristine regions of Amazonia and
biologically one of the richest areas on Earth. How and when this massive diversity arose …

In anuran amphibians, age-and size-related life-history traits vary along latitudinal and
altiudinal gradients. In the present study, we tested the hypothesis that altitudinal and …

In the toad Bufo calamita, among‐population variation of size follows roughly a converse
Bergmann cline, but populations exist that do not fit this pattern. We propose that latitudinal …

In this chapter we address sexual differences in insect development time. Although sexual
size dimorphism in insects is well documented and has been elaborated theoretically (see …

Variability in life history traits positively affects the establishment and expansive potential of
invasive species. In the present study, we analysed the variation of body size in seven …

Sexual size dimorphism (SSD) is often explained as the differential equilibrium between
stabilizing survival selection and directional sexual/fecundity selection on the body size of …

We studied the effects of salinity on the egg fertilization, hatching, and tadpole growth and
survival rates of the Thailand frog (Rana tigerina Dubois, 1981), an introduced species that …

To find out the main cause of the sexual size dimorphism (SSD) in the Cuban treefrog
Osteopilus septentrionalis, I studied between April 2002 and April 2004 the breeding …

We studied differences in age, longevity, and sexual maturity in island and mainland
populations of the neotropical toad Rhinella ornata to assess how changes in sexual …
