Risk Factors for Seabird Bycatch in a Pelagic Longline Tuna Fishery.

PLoS ONE, 2016
Capture in global pelagic longline fisheries threatens the viability of some seabird populations. The Hawaii longline tuna fishery annually catches hundreds of seabirds, primarily Laysan (Phoebastria immutabilis) and black-footed (P.

Making the most of the old age: Autumn breeding as an extra reproductive investment in older seabirds

Ecology and Evolution, 2021
The extrinsic and intrinsic factors affecting differing reproductive strategies among populations are central to understanding population and evolutionary ecology.

Seabird diving behaviour reveals the functional significance of shelf-sea fronts as foraging hotspots [PDF]

Royal Society Open Science, 2016
Oceanic fronts are key habitats for a diverse range of marine predators, yet how they influence fine-scale foraging behaviour is poorly understood. Here, we investigated the dive behaviour of northern gannets Morus bassanus in relation to shelf-sea ...

Seabird-Derived Nutrients Supply Modulates the Trophic Strategies of Mixotrophic Corals

Frontiers in Marine Science, 2022
The ability of corals to modulate their nutrition strategy in response to variable nutrient supply remains poorly understood, limiting our understanding of energy flow in coral reef ecosystems and thus our comprehension of their resilience to global ...

Seabird-vectored pelagic nutrients integrated into temperate intertidal rocky shores

Frontiers in Marine Science
Seabirds provide inter-habitat connectivity by transporting vast quantities of nutrients from their pelagic feeding grounds to terrestrial and marine ecosystems via their nitrogen and phosphorous rich guano.

A comparison of techniques for classifying behavior from accelerometers for two species of seabird

Ecology and Evolution, 2019
The behavior of many wild animals remains a mystery, as it is difficult to quantify behavior of species that cannot be easily followed throughout their daily or seasonal movements.

Assessing responses of reef island seabirds to environmental and anthropogenic drivers. [PDF]

Conserv Biol
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 ...

Land birds on atolls: diversity, origin, and function

Biological Reviews, EarlyView.
ABSTRACT Oceanic islands are global hotspots of avian biodiversity and endemism. Their isolation and distinct environmental conditions have uniquely shaped the evolutionary trajectories of island birds, while, in turn, land bird communities have become critical providers of ecological functions to island ecosystems.

Consequences of cross‐season demographic correlations for population viability

Ecology and Evolution, 2023
Demographic correlations are pervasive in wildlife populations and can represent important secondary drivers of population growth. Empirical evidence suggests that correlations are in general positive for long‐lived species, but little is known about the
