As individuals age, their body functions and survival prospects decline. Why some individuals deteriorate slower and later in life, is a critical question we cannot adequately answer, although the social environment has been suggested to be important. Using a recently established molecular biomarker of aging, this project aims to experimentally investigate in a wild bird if age-related decline is faster when individuals lack social support or face sexual competition. Expected outcomes are insights into key determinants of delayed aging and longer lifespan. Potential benefits include improved understanding of drivers of healthy aging, and improved ability to predict population persistence and identify conservation priorities. Read moreRead less
Ecological role of sleep in maintaining optimal brain function in birds. This project aims to explain the function of sleep. Sleep is thought to maintain optimal brain functioning to support waking cognition. Nearly all sleep research is laboratory-based, which fails to realistically capture how animals benefit from sleep. Ecologists treat sleep as a simple behaviour, instead of as a heterogeneous neurophysiological state, while neuroscientists generally fail to appreciate the insights ecologica ....Ecological role of sleep in maintaining optimal brain function in birds. This project aims to explain the function of sleep. Sleep is thought to maintain optimal brain functioning to support waking cognition. Nearly all sleep research is laboratory-based, which fails to realistically capture how animals benefit from sleep. Ecologists treat sleep as a simple behaviour, instead of as a heterogeneous neurophysiological state, while neuroscientists generally fail to appreciate the insights ecological and evolutionary systems offer. This project adopts a cross-disciplinary approach, bringing together animal behaviour, ecology, evolution, anthropogenic disturbance and sleep neurophysiology. By doing so, the project will add a new dimension of understanding on the functions of sleep.Read moreRead less
Growing up with global change. This project aims to quantify how native bird populations will respond to global warming. The project will investigate how vulnerable nestling birds are to high temperatures, and the impact of early-life heat stress on adult performance and fitness in the wild. Although growing animals are most sensitive to heat, and stress during early-life often has irreversible negative effects, we know very little about long-term consequences of early-life heat stress. The inte ....Growing up with global change. This project aims to quantify how native bird populations will respond to global warming. The project will investigate how vulnerable nestling birds are to high temperatures, and the impact of early-life heat stress on adult performance and fitness in the wild. Although growing animals are most sensitive to heat, and stress during early-life often has irreversible negative effects, we know very little about long-term consequences of early-life heat stress. The intended outcomes will increase our capacity to predict impacts of climate warming before population declines become evident. Improved predictions are beneficial to identify urgent threats and optimise conservation efforts.Read moreRead less
