The connection between development and evolution has become the focus of an increasing
amount of research in recent years, and heterochrony has long been a key concept in this …

The relationships between macro-ecological patterns and physiological investigations in
insects, especially those dealing with respiratory metabolism, are assessed in an attempt to …

This practical manual of amphibian ecology and conservation brings together a
distinguished, international group of amphibian researchers to provide a state-of-the-art …

Cetaceans (whales, dolphins, and porpoises) have fascinated and bewildered humans
throughout history. Their mammalian affinities have been long recognized, but exactly which …

Ecologists have always believed, at least to a certain extent, that physiological mechanisms
serve to underpin ecological patterns. However, their importance has traditionally been at …

ABSTRACT A study of ontogenetic variation is used to clarify aspects of tyrannosaurid
taxonomy and investigate the supposed phenomenon of dwarfism in the clade. A …

Heterochrony can be defined as change to the timing or rate of development relative to the
ancestor. Because organisms generally change in shape as well as increase in size during …

Most animals begin life in eggs, protected and constrained by a capsule, shell, or other
barrier. As embryos develop, their needs and abilities change, altering the costs and …

Evolutionary developmental biology (“evo-devo”) has revolutionized evolutionary biology
but has had relatively little impact on systematics. We show that similar large-scale …

Studies of phenotypic plasticity typically focus on traits in single ontogenetic stages.
However, plastic responses can be induced in multiple ontogenetic stages and traits …
