Deep refuges: the distribution of marine fish in warming subtropics

open access: yesEcography, EarlyView.
In light of global climate change, identifying critical marine habitats and conserving them is essential. Marine conservation planning recommends designating cooler habitats as marine protected areas. The ‘deep‐reef refugia' hypothesis suggests that deeper, suitable habitats may allow species to undergo the evolutionary changes necessary to adapt to ...

Mortality of Migratory Birds from Marine Commercial Fisheries and Offshore Oil and Gas Production in Canada

open access: yesAvian Conservation and Ecology, 2013
There is an imminent need for conservation and best-practice management efforts in marine ecosystems where global-scale declines in the biodiversity and biomass of large vertebrate predators are increasing and marine communities are being altered.

Transatlantic Surveys of Seabirds, Cetaceans and Turtles, July 2013 and July 2018 [PDF]

open access: yes, 2018
Analysis of multi-species tracking data suggest that an area of the deep northwest Atlantic bounded by Flemish Cap, Charlie-Gibbs Fracture Zone and Mid-Atlantic Ridge (MAR) has a relatively high abundance and diversity of pelagic seabirds.

Corticosterone and Mitochondrial Efficiency Are Associated With Changes in DNA Oxidative Damage During an Acute Stress Response in Leach's Storm‐Petrels (Hydrobates leucorhous)

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT The ability of organisms to effectively respond to challenges is critical for survival. We investigated how an acute stressor affected corticosterone, mitochondrial function, and DNA oxidative damage in a wild population of Leach's storm‐petrels (Hydrobates leucorhous).

A Comprehensive Survey of Pelagic Megafauna: Their Distribution, Densities, and Taxonomic Richness in the Tropical Southwest Indian Ocean

open access: yesFrontiers in Marine Science, 2017
The distribution and density of pelagic megafauna (marine mammals, seabirds, elasmobranches, and sea turtles) are important indicators of marine biodiversity, reflecting the condition of the underlying ecosystems.

Legacy pollutants are declining in Great Skuas (Stercorarius skua) but remain higher in Faroe Islands than in Scotland [PDF]

open access: yes, 2016
To monitor environmental pollutants in Faroese biota, samples from a top predator were analysed and put into a spatial and temporal context. Analysis of 20 Great Skua eggs sampled in 2012 from the Faroe Islands showed >70 % lower concentrations of ...

Indirect effects of fast‐growing urban development on wildlife in a coastal protected area of Costa Rica

open access: yesThe Journal of Wildlife Management, EarlyView.
We studied the effects of urban growth on wildlife near Parque Nacional Marino las Baulas, Costa Rica. Since 1991, buildings increased 1007%, mainly in the buffer zone. We identified eight native species extracting garbage from containers, with raccoons (Procyon lotor) comprising most detections (84%), and four other species being potential sea turtle ...

Development of a moored radium in situ sampler to measure annual time series

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Radium is a useful tracer of sediment‐derived materials, improving our understanding of the geochemical cycling of elements at ocean boundaries. We have developed an autonomous in situ sampler to collect time series samples of radium isotopes on mooring deployments.

Spatial and temporal variations in seabird bycatch: Incidental bycatch in the Norwegian coastal gillnet-fishery.

open access: yesPLoS ONE, 2019
The general decline of seabird populations worldwide raises large concerns. Although multiple factors are interacting to cause the observed trends, increased mortality from incidental bycatch in fisheries has proven to be important for many species ...
