A group of passionate lizard scientists have published a guide to the dozens of species of Anolis: small, brightly-coloured tree lizards related to iguanas. Colombia holds more than 75 species of ...

Figure 1: Amniote phylogeny based on protein synonymous sites showing major features of amniote evolution. Figure 2: A. carolinensis –chicken synteny map reveals synteny of reptile microchromosomes ...

We evaluated survival of the lizard, Anolis limifrons at two sites, AVA and Lutz, from 1976-1979 and during two periods at Lutz site, 1971-1976 vs 1976-1979, at Barro Colorado Island, Panama. Survival ...

Sexual dimorphism may increase the ecologically relevant variation within a community when sexes play ecologically differentiated roles. Sometimes, the ecological differences between sexes can be as ...

How do intermittent events like hurricanes impact natural selection? How do animals adapt to challenging weather? A University of Rhode Island professor has set out to track natural selection in the ...

A serendipitous find in the National Museum of Natural History’s collections yielded just the second known specimen of a mysterious Cuban anole Benjamin Hack A CT scan reconstruction of USNM 5095 that ...

Anolis lizards have a thing or two to teach humans about love -- or in scientific speak, sexual selection -- at least when it comes to territoriality. Decades of behavioral research on the lizard's ...

The Georgia Tech-led study captures two lizard species adapting in response to competition. The study provides some of the clearest evidence to date of evolution in action. A Cuban brown anole (Anolis ...

Researchers recently discovered that several species of semi-aquatic anole lizards can breathe underwater — or rebreathe — for up to 18 minutes. They observed that anoles have hydrophobic skin that ...

The movement of lizards around the Caribbean is forcing researchers to account for human activity in even their most basic ecological models. When Matthew Helmus was about eight years old and ...

Sometimes, evolutionary selection can happen within a single generation of a species, research now shows. In response to a new predator, lizards on several Caribbean islands underwent selection first ...
