Ptychoglossus bicolor is a small gymnophthalmid lizard distributed in the Magdalena Valley of Colombia. We studied ecological features of diet, microhabitat use, and thermal preferences of a population found in an organic coffee shade plantation at the Co... see more

Global warming has been recognized as a great threat for biodiversity. Particularly, it has been predicted that temperature raise could be lethal for ectothermic speciesin tropical regions, because their physiological and ecological traits are linked to s... see more

AbstractThe results of a survey of the reptiles and amphibians of the Addo Elephant National Park (AENP) are presented. A total of 49 species, comprising 16 amphibians, 14 lizards, 15 snakes and 4 chelonians, occur in the AENP. Observations on the biology... see more

Sexual dimorphism, diet, and notes on reproduction in Oxyrhopus trigeminus (Serpentes: Colubridae) in the semiarid Caatinga of northeastern Brazil. Selected morphological characters, diet, and reproduction of the false-coral snake, Oxyrhopus trigeminus, f... see more

Several factors have been shown to affect lizard escape behavior (flight initiation distance or FID, the distance between predator and prey when the prey initiates escape). Patterns of daily activity, such as foraging or movement behavior, vary with respe... see more

We studied the ecology of Alopoglossus angulatus and A. atriventris in western Amazonia. Both species are found in leaf litter of lowland tropical forest, but A. angulatus tends to be found near water whereas A. atriventris is found in terra firme forest.... see more

Several amphibian lineages epitomize the faunal biodiversity crises, with numerous reports of population declines and extinctions worldwide. Predicting how such lineages will cope with environmental changes is an urgent challenge for biologists. A promisi... see more

We report the presence of the bobcat (Lynx rufus) in the northeastern of the state of Hidalgo, in the municipality of San Felipe Orizatlán, at 156 meters of altitude. One individual male of L. rufus was run over in a dirty road and donated by local people... see more

La deforestación es una de las mayores amenazas para la vida del hombre, ya que los bosques ayudan a mantener el equilibrio ecológico y la biodiversidad, es por ello que muchos científicos hoy día se han dado a la tarea de tratar de dar solución a este pr... see more
