Growth over ontogeny can profoundly affect the form and function of biological structures. Since animal performance is tightly linked to morphological specialization, ontogenetic change in size may help structure that organism's...
Globally, species diversity is regulated by speciation and extinction, and regionally it is regulated by competition, niche, colonization, emigration, and extinction, and more locally, by environmental tolerance and species interactions...
Understanding how environmental forces, genetic variation, and developmental process combine to mold adaptations remains a core challenge in evolutionary biology. Our research is answering this challenge. More specifically we focused on...
Crustaceans release (autotomize) a limb grasped by a predator or conspecific, often as an escape tactic. However, there are potential fitness costs over the time needed to regenerate a missing limb. If anti-predatory defensive structures...
Expression of Axdazl and Axvh in Axolotl Germ Cells, Suggest that Regulative Germ Cells Specifications is a Primitive Trait Conserved in the Mammalian Lineage
How germ cells are specified in animal embryos has been a mystery for decades. Unlike most developmental processes, which are highly conserved, embryos specify germ cells in very different ways. The embryos of several prominent model...
The Late Miocene brought a sudden increase in the biomass of C4 plants that resulted in an expansion of grassland habitat and markedly changed the diets of vertebrate fauna in many places around the world. Concurrently, early pulses of...
