Observations on the ontogeny and diversity of salamanders provided some of the earliest
evidence that shifts in developmental trajectories have made a substantial contribution to the …

Organ regeneration occurs in anamniotes (fish and amphibians) while is absent in amniotes
(reptiles, birds and mammals). An evolutionary hypothesis is presented to explain the loss of …

A fundamental goal of ecology is to understand how the physical environment influences
intraspecific variability in life history and, consequently, fitness. In streams, discharge and …

We lack a strong understanding of how organisms with complex life histories respond to
climate variation. Many stream-associated species have multistage life histories that are …

Changes in the amount, intensity, and timing of precipitation are increasing hydrologic
variability in many regions, but we have little understanding of how these changes are …

We collected larvae of the Patch-nosed Salamander, Urspelerpes brucei, and analyzed size-
frequency distributions throughout a 12-mo cycle to determine the length of the larval period …

The equal fitness paradigm (EFP) is a life-history model in which the currency of fitness is
usable energy rather than individuals, and the principal trade-off is between survival …

The biphasic life history of amphibians includes metamorphosis, a complex developmental
event that involves drastic changes in the morphology, physiology and biochemistry …

The Two-lined Salamander (Eurycea bislineata) species complex is widely distributed
across semiaquatic habitats in various ecoregions of the eastern US and Canada of North …

The southeastern US has an incredibly diverse salamander fauna that contains~ 17% of the
world's species. Furthermore, there is more variation in salamander life-cycle there than …
