Body condition metrics are widely used to infer animal health and to assess costs of parasite
infection. Since parasites harm their hosts, ecologists might expect negative relationships …

Studies documenting plastic ingestion in animals have increased in recent years. Many do
not describe the less conspicuous, sub-lethal impacts of plastic ingestion, such as reduced …

Body condition indices are widely used by ecologists, but many indices are used without
empirical validation. To test the validity of a variety of indices, we compared how well a …

The ability to efficiently measure the health and nutritional status of wild populations in situ is
a valuable tool, as many methods of evaluating animal physiology do not occur in real-time …

Aim In this paper we present a scientometric analysis aimed at to assess and quantify the
contribution of Le Cren's condition factor and the main ideas advanced by 'Le Cren, 1951'to …

Per‐and polyfluoroalkyl substances (PFAS) are associated with several disrupted
physiological and endocrine parameters. Regarding endocrine mechanisms, laboratory …

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 …

Geolocators provide information on the year-round movements of birds. The effect of the
year-round deployment of such devices has, however, largely been examined via measures …

The reproductive success of wild animals usually increases with age before declining at the
end of life, but the proximate mechanisms underlying those patterns remain elusive. Young …

Animals exposed to stressful developmental conditions can experience sustained
physiological, behavioral, and fitness effects. While extensive research shows how …
