Micro‐geographic shift between negligible and actuarial senescence in a wild snake

Our new study published at Journal of Animal Ecology shows that old meadow vipers can maintain a high reproductive output and a high survival in the wild (negligible senescence). But the pattern of actuarial senescence is plastic and can shift from negligible senescence to strong senescence at a micro‐geographic scale.

Does water matter for thermoregulation?

Our new study published at Journal of Animal Ecology is a significant step forward in a scientific environment in which exploring the interaction of thermoregulation and hydroregulation processes is at the cutting edge of the study of the animal ecology of global changes. Its novelty relies in its potential to question the predictions of mechanistic niche models that neglect future changes in water availability.
