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).

Predictive Modelling to Identify Near-Shore, Fine-Scale Seabird Distributions during the Breeding Season.

open access: yesPLoS ONE, 2016
During the breeding season seabirds are constrained to coastal areas and are restricted in their movements, spending much of their time in near-shore waters either loafing or foraging. However, in using these areas they may be threatened by anthropogenic

Holocene vegetation dynamics of Grande Terre (Kerguelen Islands) inferred from sedimentary ancient DNA

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT While the Antarctic region has experienced significant climatic changes over the Holocene, few high‐resolution records have examined their effects on the local biota. In order to understand past ecological shifts and forecast future changes, it is important to obtain high‐resolution palaeoecological records from this region.

Seabirds in the North-East Atlantic

open access: yes, 2023
This book was produced by the Zoological Society of London and the University of Cambridge with two aims: to assess seabirds’ vulnerability to climate change in the North-East Atlantic, and to identify potential conservation actions that could reduce ...

Estimating the total mortality of seabirds following a marine heat wave. [PDF]

open access: yesConserv Biol
Abstract Marine heat waves detrimentally affect a range of marine species, including seabirds, and are increasing in frequency and severity. When thousands of dead seabirds wash up on beaches, the public becomes concerned. However, the number of dead birds recorded on beaches is only a fraction of the total mortality; most birds perish at sea.

White light reduces flight height of birds in low‐density migration corridor

open access: yesThe Journal of Wildlife Management, EarlyView.
We conducted an experiment to better understand the effects of artificial light at night treatments of varying spectral power distributions on in‐flight migratory bird behavior as measured by a portable radar. Broad‐spectrum white light emissions reduced avian flight height as compared to dark periods and more than other light treatments.

Masterplan Wind - Seabirds Cruise Report August 2010 [PDF]

open access: yes, 2010
This cruise report provides an overview of the fifth survey in a series of seabirds at sea surveys that will be carried out in 2010 and 2011 over the Dutch Continental Shelf (DCS) of the North Sea and adjoining waters. This fifth survey in the series was

Seabird mortality from longline fishing in the Mediterranean Sea and Macaronesian waters: a review and a way forward

open access: yesScientia Marina, 2003
A country-by-country review of seabird mortality from longline fishing in the Mediterranean Sea and in Macaronesian waters shows a paucity of data. Of 12 Mediterranean countries known to undertake longlining, seabird mortality is only reported for six ...

Area‐restricted search under realistic constraints

open access: yesOikos, EarlyView.
Abstract Area‐restricted search (ARS) is one of the most influential and widely used concepts in foraging theory, capturing a simple rule by which animals intensify local search following a resource encounter. Because ARS performs well in many spatially structured environments, it serves as a basic model for interpreting movement patterns across taxa ...

Post-mating survival in a small marsupial is associated with nutrient inputs from seabirds [PDF]

open access: yes, 2004
We investigated a link between facultative semelparity ("male die-off") in a small, endangered marsupial, Parantechinus apicalis (the dibbler), and the availability of resources on two small islands in Western Australia.
