Fitness results from an optimal balance between survival, mating success and fecundity. The
interactions between these three components of fitness vary depending on the selective …

Macroevolutionary rates of diversification and anthropogenic extinction risk differ vastly
throughout the Tree of Life. This results in a highly heterogeneous distribution of …

In recent decades, changes in climate have caused impacts on natural and human systems
on all continents and across the oceans and many species have shifted their geographic …

Physiological thermal-tolerance limits of terrestrial ectotherms often exceed local air
temperatures, implying a high degree of thermal safety (an excess of warm or cold thermal …

Behavior is one of the major architects of evolution: by behaviorally modifying how they
interact with their environments, organisms can influence natural selection, amplifying it in …

Motivation over the last 12 years I have been collecting trait and geographic data on lizards.
These data could be useful for scientists studying this remarkable reptilian radiation …

Viviparity has putatively evolved 115 times in squamates (lizards and snakes), out of only~
140 origins in vertebrates, and is apparently related to colder climates and other factors such …

Aim Size is one of the most important and obvious traits of an organism. Both small and
large sizes have adaptive advantages and disadvantages. Body size–frequency …

Climate change–induced mass extinctions provide unique opportunities to explore the
impacts of global environmental disturbances on organismal evolution. However, their …

Climatic conditions changing over time and space shape the evolution of organisms at
multiple levels, including temperate lizards in the family Lacertidae. Here we reconstruct a …
