Assessing responses of reef island seabirds to environmental and anthropogenic drivers

Conservation Biology, EarlyView.
Abstract Tropical insular ecosystems face escalating, cumulative impacts of land‐ and sea‐based ecological threats that jeopardize the long‐term sustainability of their native communities. This joint vulnerability is epitomized by reef island seabirds, which are exposed to reef decline and coastal erosion driven by climate change, reduction in prey ...

Efficacy of CagriSema for Reaching Anthropometric Treatment Targets and Cardiometabolic Outcomes: A Secondary, Post hoc Analysis of REDEFINE 1

Diabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Aims To assess the added value of absolute anthropometric targets alongside percentage weight loss in the clinical management of obesity. Materials and Methods The phase 3a, 68‐week REDEFINE 1 trial randomised adults without diabetes with BMI ≥ 30 kg/m2, or ≥ 27 kg/m2 with ≥ 1 obesity‐related complication, to once‐weekly CagriSema 2.4 mg/2.4 ...

Interior Least Tern and Piping Plover nest and brood survival at managed, off-channel sites along the central Platte River, Nebraska, USA 2001-2015

Avian Conservation and Ecology, 2018
The Platte River Recovery Implementation Program (PRRIP) and its partners invested substantial resources in creating and managing off-channel nesting habitat for Interior Least Terns (Sternula antillarum athalassos) and Piping Plovers (Charadrius melodus)

A First Indication That Rainforest Vine Proliferation Does Not Enhance Predator–Prey Interactions on the Forest Floor

Entomologia Experimentalis et Applicata, EarlyView.
Vine proliferation is a widespread consequence of tropical forest disturbance, yet its effects on ground‐level predator–prey interactions remain poorly understood. Using plasticine caterpillars deployed on the rainforest floor in north Queensland, Australia, we show that overall predation rates were unaffected by vine‐to‐tree ratio. Instead, fine‐scale

Effects of the 1997-1998 El Niño and 1998-1999 La Niña events on breeding waterbirds and sea lions in the Upper Gulf of California, México [PDF]

Geofísica Internacional, 2003
During 1998 and 1999 I monitored waterbirds nesting on Isla San Jorge, at La Purinera and on Isla Montague, in the northern Gulf of California, as well as sea lions on Isla San Jorge. During El Niño the brown boobies on San Jorge ceased breeding and left

Influenza A virus on oceanic islands: host and viral diversity in seabirds in the Western Indian Ocean.

PLoS Pathogens, 2015
Ducks and seabirds are natural hosts for influenza A viruses (IAV). On oceanic islands, the ecology of IAV could be affected by the relative diversity, abundance and density of seabirds and ducks. Seabirds are the most abundant and widespread avifauna in

Threatened cockatoo adapts foraging strategy to survive habitat loss from fire

Ibis, EarlyView.
Fire regimes are changing across the globe as a result of human‐induced climate change. For granivorous bird species, changes in fire regimes can affect seed availability and the persistence of populations. We investigated the foraging behaviour of Glossy Black Cockatoos Calyptorhynchus lathami halmaturinus, a resource specialist, following large‐scale

Migration of black terns Chlidonias niger and common terns Sterna hirundo between south Sweden and the Atlantic coast of Africa

Journal of Avian Biology
Light‐level geolocators were used to record the annual migration cycles of black terns Chlidonias niger (9 individuals, 11 journeys) and common terns Sterna hirundo (7 individuals, 11 journeys) breeding in southernmost Sweden.

Offshore wind farm prospects and bird migration: Can a protected species be considered adequately?

Global Ecology and Conservation
Offshore wind farms (OWFs) pose a potential threat to migratory birds, either as a barrier or as a result of lethal collisions. We aimed to demonstrate the temporal and spatial frames for potential mitigation measures for a rare and protected species. We
