Para la continuación del Atlas de anfibios y reptiles de Extremadura iniciado por la Asociación Arborea en 2011 en la comarca de Campo Arañuelo, se ha realizado un inventario y georreferenciación de las especies de anfibios y reptiles que se encuentren dentro del área protegida del Monumento Natural de los Barruecos y su área de influencia socio-económica, continuando de esta manera con el estudio de la herpetofauna en otra zona de Extremadura.

It was 25 degrees at dawn (that would be Fahrenheit, not Celsius), a north wind slapping against my home as I prepped for the day’s snake surveys. As a herpetologist with The Orianne Society I conduct field work throughout the Altamaha River drainage of southeastern Georgia—field work designed to monitor population trends of two great snakes, the Eastern Indigo Snake and the Eastern Diamondback Rattlesnake.

In Phoenix, we are are fortunate to have 2 of the largest city parks in the world. To visit these parks is not what most think of as visiting a city park – they are extensive native desert landscapes, criss-crossed with trails and visited by hundreds of people every day. The wildlife in these parks is intact, and for many, where iconic desert animals like the coyote and rattlesnake are first met.

Pigs are a relatively recent phenomenon in North America. Many were brought over from Europe as people from that part of the world colonized this continent. Many more pigs have escaped from farms and hunting preserves in the past few hundred years. Today, hogs can be found virtually everywhere across the United States. Once in the wild, animals that escaped from farms rapidly become feral and nearly unrecognizable from the barnyard creatures we know and love.  Hog populations can quickly form and grow as pigs reproduce and take advantage of their surroundings.

Reproductive modes in frogs vary greatly, as do the ways in which they deposit their eggs.  The túngara frog, Physalaemus pustulosus (=Engystomops), which is the main focus in my lab  constructs a «foam» nest–an adaptive character which I’ve become interested in exploring. Foamy substances are produced by some insects, tunicates, fish and, perhaps most famously, frogs.
