Post-whaling shift in mating tactics in male humpback whales
Communications Biology, 2023 AbstractRecent studies have shown behavioural plasticity in mating strategies can increase a population’s ability to cope with anthropogenic impacts. The eastern Australian humpback whale population was whaled almost to extinction in the 1960s (~200 whales) and has recovered to pre-whaling numbers (>20,000 whales).

Journal of the Royal Anthropological Institute, EarlyView.Amid the general sense of worry that large language models will soon drown out human voices, some researchers are optimistic that machine learning will allow humans to listen to and understand animal voices to an unprecedented extent. As part of a broader project aimed at interspecies communication, a loosely connected set of animal behaviourists, AI ...

Estimates of humpback and minke whale entanglements in the Scottish static pot (creel) fishery
Endangered Species Research, 2022 Entanglement in static fishing gear (pots, or creels as they are called in Scottish fisheries) is a major cause of anthropogenic mortality and morbidity in large whales globally; in northeastern Atlantic waters around the coast of Scotland, entanglement ...

Direct numerical simulations of the flow around wings with spanwise waviness at a very low Reynolds number [PDF]
, 2017 Inspired by the pectoral flippers of the humpback whale, the use of spanwise waviness in the leading edge has been considered in the literature as a possible way of improving the aerodynamic performance of wings.

Integrative Zoology, EarlyView.This work aimed to apply the principles of skin mark analysis to a cetacean species to build a sex‐discrimination model exclusively based on photographic material. Relevant differences between sexes emerged in markings, with males presenting more social, aggression‐related, and fishing‐related marks overall, and a stronger tendency of mark accumulation

Rare Sighting of a North Pacific Right Whale (Eubalaena glacialis) in Hawai'i [PDF]
, 1999 On 2 April 1996, a North Pacific right whale (Eubalaena glacialis) was sighted in the company of three humpback whales (Megaptera novaeangliae) off the western coast of Maui, Hawai'i (200 56' N, 1560 46' W). The right whale appeared to initiate social

Comparative review of entanglement risk assessments for cetacean conservation and management
Conservation Biology, EarlyView.Abstract Cetacean entanglement in fishing gear remains a major global threat that exposes persistent gaps in how fisheries management frameworks manage risk to nontarget species. Ecological risk assessment (ERA) offers a structured way to link exposure and consequences to an explicit statement of risk, but entanglement risk assessments vary widely in ...

Explaining humpback whale’ distribution and abundance in the Magellan Strait, ChileZenodo
Global Ecology and ConservationA new feeding ground for humpback whales was discovered in the Magellan Strait in 2003, which is critical habitat for a subpopulation of whales that migrate to these waters.
