Journal of Animal Ecology, EarlyView.We apply a new parameterized model through linking metabolic scaling and the maximum entropy theory of ecology to quantify the intraspecific metabolic scaling exponent of brown trout populations and assess the main drivers shaping the exponent. Abstract Metabolic scaling fundamentally sets the pace of life in almost all organisms.

Population trends and variability within bird communities are amplified by intense land use
Journal of Animal Ecology, EarlyView.We show that bird populations in farmland have stronger long‐term changes and are more variable around these changes than in woodland. Disentangling these two components of population stability helps understand the effects of anthropogenic pressures on wild communities.
