Several legal acts mandate that management agencies regularly assess biological populations. For species with distinct markings, these assessments can be conducted noninvasively via capture-recapture and photographic identification (photo-ID), which involves processing considerable quantities of data. To ease this burden, increasingly rely on automated (ID) algorithms. Identification algorithms present an opportunity-reducing the cost population assessments-and a challenge-propagating...
North Atlantic (NA) humpback whales (Megaptera novaeangliae) migrate between high‐latitude maternal feeding grounds and low‐latitude breeding/calving grounds, with one distinct breeding segment currently considered endangered: Cape Verde Islands/northwest Africa (CVI). This study assesses the movement patterns population spatial structuring of across NA Ocean basin for first time in three decades. Photo‐ID records from collections contributed to Humpback Whale Catalogue, a dataset 38,319...
Biorepositories, or biobanks, are vital to marine science. Their collections safeguard biological knowledge, enable follow-up studies and reproducibility confirmations, help extend ecological baselines. Biorepository networks data portals aggregate catalogs facilitate open material exchange. Such integrations enrich contextual support holistic ecosystem-based research management. In the Arctic, where researchers face vast scales, rapidly changing ecosystems, limited resampling opportunities,...
In this study, we compared the established MaxEnt and a more novel deep learning approach for modeling distribution of humpback whales (Megaptera novaeangliae) in north Iceland. We examined mechanisms, structures, optimization techniques both approaches, highlighting their differences similarities. Monthly models Skjálfandi Bay were created, from 2018 until 2021, using presence-only sighting data satellite remote sensing data. Search efforts boat tracklines utilized to create pseudo-absence...
Abstract Researchers can investigate many aspects of animal ecology through noninvasive photo–identification. Photo–identification is becoming more efficient as matching individuals between photos increasingly automated. However, the convolutional neural network models that have facilitated this change need training images to generalize well. As a result, they often been developed for individual species meet threshold. These single‐species methods might underperform, ignore potential...

Long-finned pilot whales and killer are widely distributed across the North Atlantic, but few studies have reported their occurrence in Icelandic coastal waters. Here, we use sightings data from research platforms whale watching tours six regions of Iceland 2007 to 2020 show that long-finned varied with region season.

Accurate reporting of cetacean bycatch in/interaction with fishing gear in fisher logbooks would be immense scientific value; however, despite some countries having mandatory laws, logbook is widely considered unreliable and catches are thought to under-reported. Despite this widespread notion unreliability, under-reporting has rarely been quantified. For study, initially we compiled the first comprehensive legislation summary for which have bycatch/interaction laws. We then used data...
Anthropogenic activity has contributed to increased extinction rates, creating a need monitor and conserve vulnerable species. Understanding the distribution habitat preference of threatened species can identify crucial habitats, for which protection improve population size numbers. Here, we investigate common minke whale, rapidly declining yet understudied cetacean We analysed whale sightings over time in relation environmental factors (depth, sea surface temperature, sediment,...
In Iceland, as in many places globally, the detrimental impacts of whale interactions with fishing gear on both fisheries and whales are not well understood managed. This study conducted anonymous questionnaires Icelandic fishers interviews capelin purse seine boat captains to gather first-hand knowledge issues face due interaction their gear. Results suggest that humpback is large species most often entangled or encircled causing damage, however occasion other interacting well. Interactions...
Surface water samples were collected using a low-tech aquatic debris instrument (LADI) at six nearshore locations on the north and northwestern coasts of Iceland to investigate prevalence mesoplastic (5–10 mm) microplastic (0.3–5 in region.

Although killer whale (Orcinus orca) predation on humpback whales (Megaptera novaeangliae) is rarely witnessed, resultant scars flukes provide evidence of non-lethal interactions. Humpback photo-identification catalogs from the North Atlantic were used to evaluate (n = 10,957) for presence and severity scarification (e.g., rake marks, teeth indentations, missing tissue). Flukes coded as none, light, moderate, or severe based extent scarring. Even with increased sample sizes, especially...
In the North Atlantic, some humpback whales (Megaptera novaeangliae) from Icelandic feeding grounds are known to migrate breeding in West Indies. The Turks and Caicos Islands (TCI) historically considered part of larger range; however, very little whale data has been reported for TCI there have no previously confirmed matches or round‐trip migrations grounds. Here, we present first documented photo‐identification match migration a between Iceland TCI.

Abstract Mitigating cetacean entanglement in fishing industries is of global interest. Strategies include the use acoustic alarms to warn whales gear.
