Thyroid hormones (THs) play a pivotal role in the regulation of metabolic activity throughout
all life stages. Cross-talk with other hormone systems permits THs to coordinate metabolic …

Group size is a fundamental component of sociality, and has important consequences for an
individual's fitness as well as the collective and cooperative behaviours of the group as a …

Individuals with more or stronger social bonds experience enhanced survival and
reproduction in various species, though the mechanisms mediating these effects are …

Feeding wildlife is a very popular tourist activity, largely because it facilitates the close
observation of animals in their natural habitat. Such provisioning may benefit animals by …

Proximate mechanisms of 'social ageing', ie shifts in social activity and narrowing of social
networks, are understudied. It is proposed that energetic deficiencies (which are often seen …

Hormones have a key role in energy allocation, so their study allows understanding
individual metabolic strategies. Because different hormones convey different information on …

Thyroid hormones are key modulators of development, as well as mediators of
environmental conditions, by regulating developmental processes and metabolism in …

Energy availability drives an individual's fitness and can be affected by diverse energetic
challenges. The assessment of hormones involved in metabolic activity and energy …

Fecal hormone analysis shows high potential for noninvasive assessment of population-
level patterns in stress and reproduction of marine mammals. However, the marine …

Understanding how environmental and social factors affect reproduction through variation in
energetic condition remains understudied in wild animals, in large part because accurately …
