Diet is a key component of a species ecological niche and plays critical roles in guiding the trajectories of evolutionary change. Previous studies suggest that dietary evolution can influence the rates and patterns of species diversification, with omnivorous (animal and plant, ‘generalist’) diets slowing down diversification compared to more restricted (‘specialist’) herbivorous and carnivorous diets.  Leer más.

While the frog may live near the stream, they don’t reproduce in them. The female frog lays her eggs in the sand. The frogs are a direct developing species, skipping a free living larval phase (aka no tadpoles). Leer más.

En un trabajo publicado en la revista Frontiers in Physiology, investigadores de la Unesp (Universidad Estadual Paulista) demostraron que los renacuajos de la especie Bokermannohyla ibitiguarauna rana arborícola endémica de la Serra da Canastra, en Minas Gerais, tienen poca capacidad de adaptación a los aumentos de temperatura, lo que puede comprometer a estos anfibios en un escenario de cambio climático o deforestación.
