Diet, phenology and body size shape nutrient release by songbirds

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Animals can dramatically alter ecosystem structure and function through the cycling and transport of nutrients in their waste. While birds are particularly capable of influencing nutrient cycles due to their high mobility, abundance, metabolism and functional diversity,

Population Genomic Structure and Demographic History of Black Guillemots Breeding Across the North Atlantic

Ecology and Evolution
Identifying genetically differentiated populations is important for successful species conservation and management, and collecting baseline population genomic data can allow us to quantify impacts from environmental changes and anthropogenic stressors ...

Environmentally induced stress affects fitness of bold and shy alike: A long‐term study of personality and feather corticosterone in Arctic‐breeding kittiwakes

Journal of Animal Ecology, EarlyView.
Quantifying how individuals differ as their environment changes around them is crucial to predict population responses to climate change. By incorporating personality, physiology and life‐history the authors show that while environmental change is likely to impact the whole population equally, when individuals are most impacted will vary across the ...

Study of the Nasal Cavity of the Cadaveric Yellow-Legged Gull (Larus michahellis atlantis) Through Anatomical Cross-Sections and Computed Tomography

Animals
Understanding the anatomy of the avian nasal cavity and paranasal sinuses is essential for diagnosing respiratory diseases and interpreting imaging findings. However, detailed tomographic descriptions of these structures are scarce in seabirds.

Miniaturized data loggers and computer programming improve seabird risk and damage assessments for marine oil spills in Atlantic Canada [PDF]

, 2012
Obtaining useful information on marine birds that can aid in oil spill (and other hydrocarbon release) risk and damage assessments in offshore environments is challenging. Technological innovations in miniaturization have allowed archival data loggers to

Demographic buffering in natural populations: A multi‐level perspective

Journal of Animal Ecology, EarlyView.
We introduce a multi‐level framework that unites stochastic elasticities with nonlinear selection to test demographic buffering. Applying it across mammals reveals a key insight: ecological robustness to variability often decouples from evolutionary constraint, reshaping how we understand resilience under environmental stochasticity.

Intercolony Comparison of Diets of Western Gulls in Central California [PDF]

, 2016
As human populations expand, they force free-ranging animals to adapt to an increasingly urban environment, resulting in changes in diets, reproductive success, and mortality.

Sustainable Development Goals Applied to the Maritime Transportation Sector: Setting Sail for the Future

Natural Resources Forum, EarlyView.
ABSTRACT The 2030 Agenda for Sustainable Development aims to eradicate poverty, protect the environment, and promote prosperity through 17 Sustainable Development Goals (SDGs). Achieving these goals requires a multi‐sectoral approach. Maritime transportation, vital to the global economy, significantly contributes to several SDGs and plays a strategic ...

Passive environmental DNA sampling: A review of current practices, limitations and future directions for biodiversity monitoring

Methods in Ecology and Evolution, EarlyView.
Abstract Passive environmental DNA (eDNA) sampling is rapidly emerging as a powerful alternative to active sampling methods (e.g. direct water sampling), with a rapidly growing diversity of tested approaches but little methodological convergence.
