Accumulating evidence shows that the body size of organisms in many taxa is declining in response to global warming. We investigated the potential effect of rising temperatures on the body size of a common toad (Bufo bufo L.) population in southern England between 1983 and 2020. The body length (SVL; in millimetres) and body mass (in grams) of 15 550 males and 4004 females arriving at their breeding pond for the first time were recorded. Leer más.

Pristimantis lojanus sp. nov. is a medium sized species of the phylogenetically strongly supported P. phoxocephalus group, and its sister species is P. torresi. The new species can be easily distinguished from its closest congeners and morphologically similar species (that also have acuminate snout with a fleshy keel) by its characteristic advertisement call and morphological features (dorsum finely tuberculate with scattered larger tubercles, flanks without longitudinal lateral folds, no markings in axilla, groin or on concealed limb surfaces, and bronze iris).

La pandemia planteó nuevas preguntas en la ciencia de conservación. Una de ellas es ¿qué impacto tiene el turismo en las poblaciones de animales silvestres?  Un equipo de científicos de la fundación Charles Darwin está intentando responder a esa pregunta por medio del análisis de miles de fotografías obtenidas durante la época de cuarentena y el regreso de los turistas a Galápagos.
