As rising global emissions and climate change amplify environmental contamination, long-term monitoring is essential to quantify trends and assess or predict impacts on wildlife. Over the past four decades, such monitoring was part of a Trilateral Monitoring and Assessment Program (TMAP), in …

The Arctic is increasingly exposed to anthropogenic contaminants, yet their physiological effects on wildlife remain poorly understood. Mercury (Hg) is of particular concern because it accumulates in polar ecosystems and biomagnifies along food webs. We investigated associations between blood Hg concentrations and …

The heterophil-to-lymphocyte (H/L) ratio is widely used as an indicator of physiological stress in birds, yet it remains largely unknown whether H/L ratios vary with age, and, if so, whether such age-specificity reflects within-individual physiological senescence or arises from selective disappearance of …

Of the many pollutants wildlife is exposed to, mercury ranks among the most toxic. In birds, mercury does not only accumulate within generations, but also is transferred across generations via maternal offloading in eggs, with higher mercury concentrations found in shells of …

Highly pathogenic avian influenza (HPAI) has become a critical threat to wildlife, shifting from a seasonal epizootic to a persistent, year-round panzootic with global consequences. Here, we summarise the origin, evolutionary mechanisms, and expanding host range of the current H5N1 virus (clade …

Abstract Since winter 2022/23, high pathogenicity avian influenza virus (HPAIV) H5N1 clade 2.3.4.4b, genotype euBB, has caused extensive mortality among wild birds. This genotype emerged in France in spring 2022 through reassortment between a gull-adapted low-pathogenicity virus and HPAIV H5N1. Phylogeographic and …

Mercury is a pervasive pollutant that readily enters the food web, accumulates within organisms and across trophic levels, and poses a significant threat to long-lived top predators, such as many seabirds. Since mercury can be deposited in feathers and therefore excreted through …

Ageing refers to a decline in individual performance with increasing age that ultimately leads to a reduction in organismal fitness. Although the physiological causes of ageing are likely to be diverse, a decrease in mitochondrial function may play a central role, as …

1. Age-dependent change in traits at the population-level level can diverge from the within-individual ageing trajectory due to selective disappearance, the biased removal or death of individuals with certain phenotypes. 2. Commonly used methods to assess, and account for, selective disappearance have …

Phenotypic responses to climate affect individual fitness, but the extent to which this translates into effects on population dynamics remains poorly understood. We assemble 213 time series on phenotypes and population sizes of wild vertebrates globally and match them with local climate …
