Were dinosaurs ectotherms or fast-metabolizing endotherms whose activities were
unconstrained by temperature? To date, some of the strongest evidence for endothermy …

Body size often varies among insular populations relative to continental conspecifics–the
'island rule'–and functional, context‐dependent morphological differences tend to track this …

Terrestrial chelonians of arid regions are frequently faced with highly variable food quality
and/or quantity and these problems could be aggravated in overgrazing areas. Then, it is …

River floodplains are disturbance-dominated landscapes where floods are major regulators
of both aquatic and nearby terrestrial communities. Amphibians are common inhabitants of …

We describe the age structures of two neighbouring terrestrial salamander populations. The
skeletochronological method was also used on larvae in utero and on new-born individuals …

Density‐dependent habitat selection has been used to predict and explain patterns of
abundance of species between habitats. Thermal quality, a density‐independent component …

Animals are constantly submitted to internal and external constraints. The processes that
regulate the acquisition and allocation of resources among the competing demands of …

In most animal species, it is expected that females should exhibit a greater abdominal
volume than males to hold the progeny, when compared with females, males should exhibit …

Body size is directly linked to key life history traits such as growth, fecundity, and
survivorship. Identifying the causes of body size variation is a critical task in ecological and …

Using skeletochronology, we compared age structure in the breeding season in two
populations (Katata, Shiga Pref. and Shizuhara, Kyoto Pref.) of a pond frog, Rana …
