The number of studies investigating links between among-individual differences in
metabolic rate (MR) and behavior has grown dramatically in the past several years. A major …

The first comprehensive review of all aspects of the biology of moult, drawing information
from across the literature and in all birds, from penguins to passerines. Feathers are …

Many ecosystems have experienced anthropogenically induced changes in biodiversity, yet
predicting these patterns has been difficult. Recently, individual behavioural and …

The Qinghai-Tibetan Plateau, with low precipitation, low oxygen partial pressure, and
temperatures routinely dropping below− 30° C in winter, presents several physiological …

The Arctic is warming at approximately twice the global rate, with well-documented indirect
effects on wildlife. However, few studies have examined the direct effects of warming …

Arctic species encounter multiple stressors including climate change and environmental
contaminants. Some contaminants may disrupt hormones that govern the behavioural …

Basal metabolic rate (BMR), the minimal energetic cost of living in endotherms, is known to
be influenced by thyroid hormones (THs) which are known to stimulate in vitro oxygen …

Reproduction is energetically expensive, and daily energy expenditure (DEE) often peaks
during the period of rearing young. The 'potentiation'hypothesis predicts that high DEE …

Unilateral vestibular lesions induce a vestibular syndrome, which recovers over time due to
vestibular compensation. The therapeutic effect of L-Thyroxine (L-T4) on vestibular …

A higher proportion of long‐lived animals die from senescence than short‐lived animals, yet
many long‐lived homeotherms show few signs of physiological ageing in the wild. This may …
