Fall feeding aggregations of fin whales off Elephant Island (Antarctica) [PDF]
From 13 March to 09 April 2012 Germany conducted a fisheries survey on board RV Polarstern in the Scotia Sea (Elephant Island - South Shetland Island - Joinville Island area) under the auspices of CCAMLR.

ABSTRACT As passive acoustic monitoring (PAM) datasets expand, studies increasingly use automated detectors to analyze baleen whale presence. However, detector errors like false positives (impacting precision, P; proportion of detected calls that are correct), and false negatives (impacting recall, R; proportion of available calls successfully detected)

Correcting Lipid Extraction Effects on Nitrogen Isotopic Values (δ15N) in Cetacean Skin
ABSTRACT Stable isotopes of carbon (δ13C) and nitrogen (δ15N) are widely used to study the feeding ecology of cetaceans, as they provide critical insights into diet and migratory behaviors. Lipids in tissues may bias the interpretation of δ13C. Because of this, lipids need to be extracted before measuring stable isotope ratios, but their removal may ...

Timing is everything: Drivers of interannual variability in blue whale migration. [PDF]
Blue whales need to time their migration from their breeding grounds to their feeding grounds to avoid missing peak prey abundances, but the cues they use for this are unknown.

Applying the Ecological Trap Concept to Cetaceans
ABSTRACT Wild animals may select poor‐quality habitats due to mismatches between perceived and actual habitat quality, creating ecological traps. Although well explored in terrestrial systems, this concept remains underutilized for marine species.

Baleen whales are key consumers in marine ecosystems and can serve as ecosystem sentinels. Body condition, defined as an individual’s energy stores relative to its structural size, can provide a useful proxy for health in baleen whales.

Population Demographics of Killer Whales (Orcinus orca) in Western Australia
ABSTRACT Understanding population demographics is crucial for the effective conservation of species. This is particularly important for apex predators, such as the killer whale (Orcinus orca), which play important roles in maintaining the structure and function of ecosystems. In this study, we used capture‐mark‐recapture (CMR) modeling to assess killer
