Patrick S. Fitze, Virginia González Jimena, Luis M. San-Jose, Benoit Heulin and Barry Sinervo. Front. Ecol. Evol. 11 (2014). Here we tested this prediction using the common lizard Zootoca vivipara, a species with three male color morphs (orange, white, yellow) that exhibit morph frequency cycles. In a first step we tested the congruence of the morph frequency change with the predicted change in three independent populations, differing in male color morph frequency and state of the FD morph cycle.

Un trabajo colaborativo entre Argentina y Rumania posibilitó que científicos de ese país brinden una serie de presentaciones en la Universidad Nacional del Nordeste y la Universidad Nacional de Misiones. El proyecto es dirigido por el investigador del Conicet, doctor Federico Marangoni. Leer más.

In the 1970s, ecologists published results from one of the first whole-forest ecosystem studies ever conducted. Scientists reported that salamanders represent one of the largest sources of biomass, or food, of all vertebrates in the forest. Now, using new techniques, a study has estimated that the population of salamanders in forested regions may be on average 10 times higher than previously thought. Leer más.

Salamander populations are much larger in some US forests than scientists once thought. That’s really good news for vertebrates, which rely on the amphibians as a major source of food. Leer más.
