Age validation of quillback rockfish (Sebastes maliger) using bomb radiocarbon [PDF]

, 2005
Rockfishes (Sebastes spp.) support one of the most economically important f isheries of the Pacific Northwest and it is essential for sustainable management that age estimation procedures be validated for these species.

Characterization of salmon‐foraging harbor seals (Phoca vitulina) in the Erimo region, Hokkaido, Japan, using finite mixture models

The Journal of Wildlife Management, Volume 90, Issue 2, February 2026.
Finite mixture models revealed that older, larger harbor seals specialize in salmon predation at setnets in Hokkaido, Japan, suggesting targeted management strategies focusing on these specialist individuals could effectively reduce fishery conflicts while protecting the broader seal population.

Assemblage, archive, and ancestor: Developing more‐than‐human historical geography with salmon

Geographical Research, Volume 64, Issue 1, February 2026.
This paper interrogates recent geographic literature on the more‐than‐human archive and argues that there needs to be more specificity when conceptualising and researching the more‐than‐human. It then answers this call for specificity by theorising three modes of more‐than‐human historical geography that are developed through empirical encounters with ...

Epigenetic Age Estimation for Hawaiian False Killer Whales (Pseudorca crassidens) in the Absence of ‘Known‐Age’ Individuals

Molecular Ecology Resources, Volume 26, Issue 2, February 2026.
ABSTRACT Epigenetic aging models hold great promise for enhancing many aspects of wildlife research and management. However, their utility is limited by the need to train models using known‐aged animals, which are rare among wildlife species. We present a novel approach to developing methylation‐based age prediction models that enables us to train ...

Morphology of the inner and peripheral ear of the loricariid catfish Pterygoplichthys gibbiceps K. [PDF]

, 2008
The morphology of the peripheral and inner ear structures was studied in the loricariid catfish Pterygoplichthys gibbiceps. Specimens (n=6) were preserved in fixative (4% paraformaldehyde, 2% glutaraldehyde in 0.1M phosphate buffer) and dissected for ...

Differential effects of freshwater browning across fish species: consequences for individual‐ to community‐level fish traits in north temperate lakes

Biological Reviews, Volume 101, Issue 1, Page 128-146, February 2026.
ABSTRACT The browning of freshwater ecosystems is increasingly evident in temperate and northern regions, with widespread ramifications for lake physics, chemistry, and biology. Contrasting results on how freshwater browning may impact fish have been reported, but there has been no comprehensive examination of how browning may cause cascading effects ...

A method to improve size estimates of walleye pollock (Theragra chalcogramma) Atka mackerel (Pleurogrammus monopterygius) consumed by pinnipeds: digestion correction factors applied to bones and otoliths recovered in scats [PDF]

, 2004
The lengths of otoliths and other skeletal structures recovered from the scats of pinnipeds, such as Steller sea lions (Eumetopias jubatus), correlate with body size and can be used to estimate the length of prey consumed.
