Abstract Incidental mortality (bycatch) in fisheries remains the greatest threat to many large marine vertebrates and is a major barrier sustainability. Robust assessments of bycatch risk are crucial for informing effective mitigation strategies, but hampered by missing information on distributions key life‐history stages (adult breeders non‐breeders, immatures juveniles). Using comprehensive biologging dataset (1,692 tracks, 788 individuals) spanning all stages, we assessed spatial overlap...
Environmental and anthropogenic factors often drive population declines in top predators, but how their influences may combine remains unclear. Albatrosses are particularly threatened. They breed fast-changing environments, extensive foraging ranges expose them to incidental mortality (bycatch) multiple fisheries. The albatross community at South Georgia includes globally important populations of three species that have declined by 40-60% over the last 35 years. We used steps deeply...
Theoretical and empirical studies have highlighted the effects of age on several life-history traits in wild populations. There is also increasing evidence for environmental their demographic traits. However, quantifying how individuals differentially respond to variations according remains a challenge ecology. In population Black-browed Albatrosses monitored during 43 years, we analyzed varied age, whether different ages responded ways conditions. To do so, we: (1) examined affected seven...
The canalization hypothesis postulates that the rate at which trait variation generates in average individual fitness a population determines how buffered traits are against environmental and genetic factors. ranking of species on slow‐fast continuum – covariation among life‐history describing species‐specific life cycles along gradient going from long life, slow maturity, low annual reproductive output, to short fast high output strongly correlates with relative impact given amount adult...
Abstract Many animal taxa exhibit sex‐specific variation in ecological traits, such as foraging and distribution. These differences could result responses to change, but demographic effects are poorly understood. Here, we test for the demography of northern (NGP, Macronectes halli ) southern (SGP, M. giganteus giant petrels – strongly sexually size‐dimorphic birds that breed sympatrically at South Georgia, Atlantic Ocean. Both species feed sea or on carrion land, larger males (30% heavier)...
Climate changes include concurrent in environmental mean, variance and extremes, it is challenging to understand their respective impact on wild populations, especially when contrasted age-dependent responses climate occur. We assessed how mean standard deviation of sea surface temperature (SST), frequency magnitude warm SST extreme climatic events (ECE) influenced the stochastic population growth rate log( λ s ) age structure a black-browed albatross population. For around historical levels...
Abstract Invasive species present a major conservation threat globally and nowhere are their affects more pronounced than in island ecosystems. Determining how native populations respond demographically to invasive can provide information mitigate the negative effects of species. Using 20 years mark-recapture data from three sympatric albatrosses (black-browed Thalassarche melanophris , grey-headed T. chrysostoma light-mantled Phoebetria palpebrata ), we quantified influence European rabbits...
The dangers of co-administration opioid pain relievers (OPRs) and benzodiazepines (BZDs) are well documented. combination OPRs BZDs make up the majority medications involved in prescription drug-related overdose often used concomitantly. This pattern is consistent among veteran population where mental health illness substance abuse prominent. Veterans Health Administration implemented Opioid Safety Initiative (OSI) aimed at improving patient safety surrounding OPRs. In alignment with OSI,...
Abstract Allocation decisions depend on an organism's condition which can change with age. Two opposite changes in life‐history traits are predicted the presence of senescence: either increase breeding performance late age associated terminal investment or a decrease due to trade‐offs between current and future survival decreased efficiency at old Age variation several has been detected number species, demographic performances individuals given year influenced by their reproductive state...
In long-lived species only a fraction of population breeds at given time. Non-breeders can represent more than half adult individuals, calling in doubt the relevance estimating demographic parameters from sole breeders. Here we demonstrate importance considering observable non-breeders to estimate reliable traits: survival, return, breeding, hatching and fledging probabilities. We study quasi-biennial breeding wandering albatross (Diomedea exulans). this species, cycle lasts almost year...
Climate change, fisheries and invasive species represent three pervasive threats to seabirds, globally. Understanding the relative influence compounding nature of marine terrestrial on demography seabird communities is vital for evidence-based conservation. Using 20 years capture-mark-recapture data from four sympatric albatross (black-browed Thalassarche melanophris , gray-headed T. chrysostoma light-mantled Phoebetria palpebrata wandering Diomedea exulans ) at subantarctic Macquarie...
