Un estudio liderado por la Estación Biológica de Doñana del CSIC, ubicada en Sevilla, ha demostrado por primera vez que los cambios que realizan los organismos para ajustar su comportamiento, morfología y estrategia de vida a los cambios ambientales conllevan costes fisiológicos relacionados con el estrés oxidativo.

The genus Proceratophrys currently comprises 40 species, of which five are distributed within the Caatinga domain and associated phytophysiognomies along northeastern Brazil. During field surveys at high altitudinal sites in Boqueirão da Onça region, northern Bahia state, we collected individuals of Proceratophrys that could not be assigned to any species currently known to occur within the Caatinga, which we describe herein.

Pesticides are useful for killing weeds (herbicides), fungi (fungicides), insect pests in agriculture and fleas in pets (insecticides). They are also used to reduce the numbers of biting insects in urban and rural environments. We have recently studied the indirect health effects on frogs of a biopesticide that has been in use for several decades, mainly to reduce the number of bothersome mosquitoes.
