Population Demographics of Killer Whales (Orcinus orca) in Western Australia
Marine Mammal Science, Volume 42, Issue 2, April 2026.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

The Southern Ocean and the Patagonian Toothfish [PDF]
, 2009 Extensive fishing industry is occurring in the area of the world known as the Southern Ocean (Kock et al., 2006). One of the main targets of this industry is Dissostichus eleginoides, commonly known as the Patagonian toothfish, or Chilean Sea Bass ...

, 2022 The identification of discrete self-sustaining productive units in marine populations is essential for achieving sustainable fisheries objectives. Marine fish populations frequently exhibit dynamic characteristics across their life-histories, displaying ...

Parasite, 2018 Two deep-sea shark species were obtained as by-catch of the local fishery of the Patagonian toothfish, Dissostichus eleginoides, at depths ranging from 1000 to 2200 m off central and northern Chile. A total of 19 parasite taxa were found in 133 specimens

Larval and juvenile distribution and growth of Patagonian toothfish around South Georgia [PDF]
Antarctic Science, 2002 Early stages of toothfish are reported from cruises between 1978 and 2001. South Georgia was regularly sampled, Shag Rocks was briefly sampled in three summers, and Burdwood Bank was sampled in 1997. Most samples were using 8 m2 and 1 m2 nets in the upper 250 m and upper 3 m, respectively.

Oikos, Volume 2025, Issue 11, November 2025.The variability in responses to environmental change between populations remains poorly quantified and understood. This shortcoming has major consequences, as variation and flexibility of life‐history traits between populations contribute to the estimation of the adaptive potential, which is necessary for predicting the responses of interconnected ...

How do seabirds modify their search behaviour when encountering fishing boats?
PLoS ONE, 2019 Seabirds are well known to be attracted by fishing boats to forage on offal and baits. We used recently developed loggers that record accurate GPS position and detect the presence of boats through their radar emissions to examine how albatrosses use Area

Immersion patterns alone can predict vessel following by albatrosses
Journal of Applied Ecology, Volume 62, Issue 8, Page 1831-1843, August 2025.We demonstrate that seabird immersion patterns alone can detect high‐risk seabird‐vessel interactions, even in the absence of locational data for both seabirds and vessels. Our approach could allow for more comprehensive seabird bycatch risk assessments that quantify previously hidden seabird‐vessel interactions, such as those involving migratory life ...
