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,

Mobile consumers influence the shoreward edge of intertidal seagrass ecosystems

Journal of Animal Ecology, EarlyView.
Ecological paradigms suggest that the environmentally stressful edge of a habitat is determined by physical factors. The work finds that, counter to these paradigms, an environmentally stressful edge can also be impacted by biotic interactions and are more complex than suggested.

Environmental drivers of metapopulation dynamics throughout the full annual cycle in a declining Arctic‐nesting migratory herbivore

Journal of Animal Ecology, EarlyView.
We provide a framework for extending commonly used integrated population models to a metapopulation framework for testing novel ecological hypotheses about how changing environmental conditions within and among subpopulations drive changes in animal abundance.

First record of the Aztec Rail (Rallus tenuirostris) in Coahuila, Mexico

Huitzil
Historically, the Aztec Rail (Rallus tenuirostris) has been recorded in the wetlands of the Mexican Transvolcanic Belt, and recently in wetlands and along river edges in Chihuahua and Durango. As participants in a citizen science birdwatching collective

Cardiovascular Plasticity and Adaptation of High‐Altitude Birds and Mammals

Integrative Zoology, EarlyView.
This schematic depicts the cardiovascular adaptations of mammals and birds to high‐altitude hypoxia. It highlights key phenotypic changes in oxygen transport and cardiac responses, driven by molecular mechanisms including transcriptional regulation and genetic modifications.

Balancing between predation risk and food by boreal breeding ducks

Ecology and Evolution
Wetlands belong to the globally most threatened habitats, and organisms depending on them are of conservation concern. Wetland destruction and quality loss may affect negatively also boreal breeding ducks in which habitat selection often needs balancing ...

eDNA enhances detection efficiency but reveals lower waterbird diversity: A comparison with point counting method

Avian Research
Environmental DNA (eDNA) methods have emerged as a promising tool for studying a broad spectrum of biological taxa. However, metabarcoding studies of avian biodiversity using eDNA have received little attention.
