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.

Waterbird zoogeochemical effects shape wetland nutrient dynamics and algal communities in Laurentian Great Lakes coastal freshwater wetlands

Journal of Animal Ecology, EarlyView.
Distinct waterbird species influence nutrient cycling through guano contributions in Great Lakes coastal wetlands. Waterbird‐derived nutrients favour distinct algal communities and wetland sediments rapidly remove waterbird nutrients via biogeochemical processes.

Climate-Altered Wetlands Challenge Waterbird Use and Migratory Connectivity in Arid Landscapes

Scientific Reports, 2019
Wetlands in arid landscapes provide critical habitat for millions of migratory waterbirds across the world and throughout their annual cycle. The scope and scale of understanding avian use of these wetlands in conjunction with changes in climate are ...

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.

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

Prey Partitioning in a Diverse Carnivore Community: Implications for Reintroduced Fishers in Washington

Animal Conservation, EarlyView.
Using fecal DNA metabarcoding, we quantified dietary overlap among reintroduced fishers and sympatric coyotes, bobcats, and Pacific martens in Washington's North Cascades. Niche overlap was substantial for common prey but varied with body size, revealing fine‐scale resource partitioning that may limit fishers' access to energetically efficient prey ...

An evaluation of the use of predicted harness spans for correctly fitting leg-loop harnesses in seabird research [PDF]

, 2015
Leg-loop harnesses for the attachment of telemetry devices have been used for over two decades in terrestrial bird research. Recently, the technique has been extended to waterbird applications.

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 ...

Changes in Site Occupancy of Marsh‐Breeding Frogs Are Associated With Surrounding Land Cover: Implications for Conservation Planning

Animal Conservation, EarlyView.
To help ensure the growth and persistence of frog populations, we quantified changes in frog occurrence as a function of concurrent changes in land cover in the surrounding landscape of eight marsh‐breeding frog species, or groups of species. We used data from the Great Lakes Marsh Monitoring Program delivered by Birds Canada at 377 sites across four ...

Swedish Bird Survey: Swedish waterbird census (September) [PDF]

The Swedish waterbird census in September (Svensk sjöfågelinventering (september)) was started in 1973 as a complement to the Swedish part of the international midwinter census (Swedish waterbird census (January)).
