Life‐stage variation in Sable Shearwater (Ardenna carneipes) physiology assessed using proteomics

open access: yesIbis, EarlyView.
Life‐stage transitions in seabirds involve substantial shifts in physiological demands, yet the molecular mechanisms underpinning these changes remain poorly resolved. Here we applied untargeted data‐independent acquisition mass spectrometry (DIA‐MS) to characterize and compare the plasma proteomes of fledgling and adult Sable Shearwaters Ardenna ...

Counter‐factual simulation highlights requirements for additional management to avert extinction of a relict Tītī/Sooty Shearwater population

open access: yesIbis, EarlyView.
Seabirds play key ecological roles but face increasing threats worldwide. Among them, Tītī (Sooty Shearwater) Ardenna grisea are among the most abundant and culturally significant species in the Southern Hemisphere but are also threatened. Kapiti Island, Aotearoa (New Zealand), holds a Tītī colony which, despite eradication of non‐native mammalian ...

Geolocation reveals wintering sites of near‐extinct Caucasian breeding sea duck

open access: yesIbis, EarlyView.
We obtained 14 sets of full annual cycle geolocator tracks from 13 individual nesting female Velvet Scoter Melanitta fusca from the relict Caucasian population at their last remaining breeding site, Lake Tabatskuri, Georgia. Results showed that females wintered at widespread discrete localities in Ukraine, around the coasts of the Crimean Peninsula and

A systematic review and meta‐analysis of variation in nest predation of ground‐nesting birds

open access: yesIbis, EarlyView.
Predation and communities of predators of ground‐nesting bird nests and fledglings have been studied across multiple groups of ground‐nesting birds, such as waders, waterbirds, gamebirds and passerines, and habitats, but differences and similarities between groups are less studied.

Under the cover of darkness: Foraging behaviour increases on cloudy, new moon nights in a pelagic seabird

open access: yesIbis, EarlyView.
While many visual predators feed exclusively during the day, others exploit foraging opportunities at night, although the efficiency with which they do so is strongly influenced by ambient light levels. We investigated the influence of variation in nocturnal light on the foraging behaviour of a small pelagic seabird, the European Storm‐petrel ...

The former distribution of White‐tailed Eagles in Iberia, the Mediterranean and the Middle East: a case study of the importance of understanding historical distribution in informing current conservation and restoration interventions

open access: yesIbis, EarlyView.
The importance of considering historical data in developing conservation and restoration measures for individual species and for wider ecological restoration has been pointed out by recent reviews but often remains neglected in practice. This paper provides a case study illustrating the issue through a review of the former breeding distribution of the ...

Seasonal variation in preen gland secretions of Tristram's Storm Petrel (Hydrobates tristrami)

open access: yesIbis, EarlyView.
Preen gland secretions are known to vary depending on sex, season and species and are thought to play essential roles in avian life history. However, their chemical composition and functions remain largely unclear in Procellariiform seabirds with well‐developed olfactory senses. Storm petrels, known for their distinctive body odour, may use preen gland

Seasonal shifts in network structure and species roles in a tropical island plant–flower visitor community Cambios estacionales en la estructura de la red de interacciones entre plantas y visitantes florales y en los roles de las especies en una comunidad insular tropical

open access: yesInsect Conservation and Diversity, EarlyView.
Constant visitation rates across the flowering season masked major shifts in plant and flower visitor interaction structure, specialization, species roles and trait‐driven patterns shaping interaction intensity. Plants and flower visitors changed ecological roles over time, with native flower visitors playing key roles in maintaining network cohesion ...

Larval Arctic cod (Boreogadus saida) exhibit stronger developmental and physiological responses to temperature than to elevated pCO2

open access: yesJournal of Fish Biology, EarlyView.
Abstract High‐latitude ecosystems are simultaneously warming and acidifying under ongoing climate change. Arctic cod (Boreogadus saida) are a key species in the Arctic Ocean and have demonstrated sensitivity to ocean warming and acidification as adults and embryos, but their larval sensitivity to the combined stressors is unknown. In a laboratory multi‐

Polar cod Boreogadus saida occurrence is driven by temperature at the margin of its distribution

open access: yesJournal of Fish Biology, EarlyView.
Abstract With a warming Arctic, suitable habitat for polar cod Boreogadus saida (Lepechin 1774) is predicted to decrease. We investigated the changes in distribution of polar cod on the southern limit of its distribution in the Atlantic Ocean (around Iceland) during both autumn and spring after a recent period of warming in the area.
