Though cell size varies between different cells and across species, the nuclear-to-
cytoplasmic (N/C) ratio is largely maintained across species and within cell types. A cell …

Simple Summary The metabolic conversion of resources into living structures and processes
is fundamental to all living systems. The rate of metabolism ('fire of life') is critical for …

Island vertebrates have evolved a number of morphological, physiological, and life history
characteristics that set them apart from their mainland relatives. However, to date, the …

Comparative studies of mortality in the wild are necessary to understand the evolution of
aging; yet, ectothermic tetrapods are underrepresented in this comparative landscape …

Endothermy, ie the endogenous production of metabolic heat, has evolved multiple times
among vertebrates, and several strategies of heat production have been studied extensively …

Although polyploidization is frequent in development, cancer, and evolution, impacts on
animal metabolism are poorly understood. In Xenopus frogs, the number of genome copies …

Cells adopt a size that is optimal for their function, and pushing them beyond this limit can
cause cell aging and death by senescence or reduce proliferative potential. However, by …

Sperm length is highly variable across species and many questions about its variation
remain open. Although variation in body mass may affect sperm length evolution through its …

Accurate estimates of genome sizes are important parameters for both theoretical and
practical biodiversity genomics. Here we present a fast, easy‐to‐implement and accurate …

Paleophysiology is an emergent discipline. Organismic (integrative) approaches seem more
appropriate than studies focusing on the variation of specific features because traits are …
