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

Ibis, 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 ...

Interactions Between Killer Whales (Orcinus orca) and Neonate Long‐Finned Pilot Whales (Globicephala melas) off South Iceland

Ecology and Evolution
Cetacean interactions can be diverse and complex, spanning agonistic to affiliative behaviors. While killer whales are known for complex hunting strategies and a wide range of prey worldwide, they also engage in various non‐predatory interspecific ...

The Greenland–Scotland Ridge in a Changing Ocean: Time to Act?

Marine Ecology, EarlyView.
ABSTRACT The Greenland–Scotland Ridge is a submarine mountain that rises up to 500 m below the sea surface and extends from the east coast of Greenland to the continental shelf of Iceland and across the Faroe Islands to Scotland. The ridge not only separates deeper ocean basins on either side, that is, the North Atlantic and Arctic oceans, but also ...

Influence of natural factors and anthropogenic stressors on sperm whale foraging effort and success at high latitudes [PDF]

, 2015
Behavioural responses can reveal important fitness trade-offs and ecological traps in evolutionarily novel contexts created by anthropogenic stimuli, and are of increasing conservation concern due to possible links to population-level impacts.

Independent acoustic variation of the higher- and lower-frequency components of biphonic calls can facilitate call recognition and social affiliation in killer whales.

PLoS ONE, 2020
Each resident-type (R-type) killer whale pod has a set of stereotyped calls that are culturally transmitted from mother to offspring. The functions of particular call types are not yet clearly understood, but it is believed that calls with two ...

Architecture of the cardiac transverse–axial tubular system across different mammalian species

The Journal of Physiology, EarlyView.
Abstract figure legend Mammalian species differ in ventricular TATS architecture, and cytoplasmic distance to the nearest TATS element covaries with lifespan, body mass, and resting heart rate. Abstract Cardiac excitation–contraction coupling relies on a pancellular network of regular cardiomyocyte surface membrane invaginations, termed the transverse ...

False killer whale and short-finned pilot whale acoustic identification

Endangered Species Research, 2015
False killer whales Pseudorca crassidens and short-finned pilot whales Globicephala macrorhynchus are known to interact with long-line fishing gear in Hawaiian waters, causing economic loss and leading to whale injuries and deaths.
