Geolocation and immersion loggers reveal year‐round residency and facilitate nutrient deposition rate estimation of adult red‐footed boobies in the Chagos Archipelago, tropical Indian Ocean

Journal of Avian Biology
Bio‐logging has revealed much about high‐latitude seabird migratory strategies, but migratory behaviour in tropical species may differ, with implications for understanding nutrient deposition.

Interspecific synchrony of seabird population growth rate and breeding success [PDF]

, 2013
Environmental variability can destabilize communities by causing correlated interspecific fluctuations that weaken the portfolio effect, yet evidence of such a mechanism is rare in natural systems.

When is the bait worth the risk? A mechanistic model of a compensatory ecological trap in seabirds

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecological traps occur when organisms preferentially select habitats that reduce fitness. In seabird–fishery systems, fishery‐derived trophic subsidies can increase foraging success, reinforce habitat preference and indirectly enhance reproductive output or recruitment,

Cross‐Validation of Diet Determination Methods for Seabird Conservation

Environmental DNA
Seabirds are recognized as one of the most vulnerable groups of birds, with around a third of species identified as globally threatened. The conservation of seabirds is often linked with their feeding and diet, due to undesirable interactions with human ...

Multi-Year Mortality Due to Staphylococcal Arthritis and Osteomyelitis with Sandspur-Associated Injury in Juvenile Black Skimmers (Rynchops niger) at Nesting Colonies in Southwest Florida, USA

Veterinary Sciences
The black skimmer (Rynchops niger) is a state-threatened, colonially nesting seabird in Florida, USA. Conservation threats include habitat alteration, human disturbances, severe weather, and predation.

Contrasting associations between parental coordination and breeding success in albatrosses across differing environmental contexts

Journal of Animal Ecology, EarlyView.
Our study demonstrates that the benefits of parental coordination in albatrosses are context‐dependent rather than universal. Coordinated parental care enhanced reproductive success in stable environments, but had little effect in variable environments, where individual flexibility may be more valuable.

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 ...

Competition and Facilitation Influence Central Place Foraging Ecology in a Colonial Marine Predator

Ecology and Evolution
Coloniality is strongly shaped by aspects of social foraging behaviour. For example, colonies may be important sources of information, while food competition may increase foraging efforts and limit colony size.

Timing the Sacred: A Multi‐Step Chronological Framework for the Llullaillaco Inca Burial

Archaeometry, EarlyView.
ABSTRACT Absolute radiocarbon dating offers high precision, but its application to historical contexts, such as the Inca civilization, requires a rigorous methodological approach. This research examines methods to enhance chronological accuracy through a case study of artifacts from the Llullaillaco Capacocha sacrifice.
