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 ...

Animal translations: AI and the intelligibility of non‐human worlds Traduire l'animal : l'IA et l'intelligibilité des mondes non humains

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 ...

Modeling Skin Mark Temporal Variations to Estimate the Sex of Delphinids with Low Sexual Dimorphism: Implications for Management and Conservation

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

Humpback whales of the Persian Gulf [PDF]

, 2017
Abstract The humpback whale has long been considered a rare straggler into the Persian Gulf, however new evidence contradicts this concept. We here critically review published and new records for Megaptera novaeangliae occurrence in the Gulf for the period 1883-2017.

Humpback whales feed on hatchery-released juvenile salmon [PDF]

Royal Society Open Science, 2017
Humpback whales are remarkable for the behavioural plasticity of their feeding tactics and the diversity of their diets. Within the last decade at hatchery release sites in Southeast Alaska, humpback whales have begun exploiting juvenile salmon, a ...

Fishing Activity Affected Odontocete Cetacean Distribution in a Marine Protected Area in the East China Sea

Integrative Zoology, EarlyView.
Spatiotemporal distribution of odontocete cetaceans within China's Jiushan Archipelago National Nature Reserve was investigated. Fishing vessels significantly reduced both cetacean acoustic detections and feeding activity, whereas gillnets selectively suppressed cetacean feeding behavior without affecting overall cetacean detection rates.

Comparing the underwater soundscape of the Hawaiian Islands Humpback Whale National Marine Sanctuary and potential influences of the COVID-19 pandemic

Frontiers in Marine Science
Passive acoustic monitoring is an effective technique for long-term monitoring of the soundscape in marine protected areas. Ocean noise is a key concern for the U.S.

Multi-year presence of humpback whales in the Atlantic sector of the Southern Ocean but not during El Niño

Communications Biology, 2021
Schall et al. use passive acoustic recordings of humpback whale calls to report the presence of humpback whales in the Atlantic sector of the Southern Ocean between 2011 and 2018. This serves as the first long-term report of humpback whales on a Southern

Maximizing eDNA detections of rare marine organisms: A case study of a delphinid species

Methods in Ecology and Evolution, EarlyView.
Abstract Environmental DNA (eDNA) is an emerging tool for surveying marine organisms. Advances in molecular assay designs and bioinformatic methods provide new opportunities for detecting rare species; however, overcoming methodological challenges of rare species detection remains an important obstacle for the widespread deployment of eDNA methods for ...

Novel class identification: A human‐in‐the‐loop approach for efficient species recognition in bioacoustic data

Methods in Ecology and Evolution, EarlyView.
Abstract Passive acoustic monitoring (PAM) is widely used to collect large‐scale wildlife data encompassing many species, but efficiently identifying all species—particularly rare and potentially endangered ones—without exhaustive manual examination of the entire dataset remains a major challenge.
