Patterns in spiny dogfish consumption by sex and maturity stage relate to prey availability and environmental forcing in the Northwest Atlantic

Frontiers in Marine Science
The spiny dogfish (Squalus acanthias) is a small mesopredatory shark found in temperate and subtropical waters worldwide and is the most abundant shark within the Northwest Atlantic.

Seasonal movements of killer whales between Iceland and Scotland

Aquatic Biology, 2015
Understanding the movements and distribution of killer whales Orcinus orca is important for evaluating the threats they face, as well as their impact as top predators in different ecosystems.

Studying of Trachurus trachurus (Linnaeus, 1758) Population Reproductive Dynamics in the Eastern Moroccan Mediterranean

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Horse mackerel (Trachurus trachurus) populations along the eastern Moroccan Mediterranean coast were studied over 12 months using 390 specimens to assess reproductive ecology. The species showed two spawning periods—late winter to early spring and summer—and exhibited fractional spawning, with males being more predominant.

Evolution of fast-growing piscivorous herring in the young Baltic Sea

Nature Communications
The circumstances under which species diversify to genetically distinct lineages is a fundamental question in biology. Atlantic herring (Clupea harengus) is an extremely abundant zooplanktivorous species that is subdivided into multiple ecotypes that ...

Temporal changes in the dietary niche of sympatric seals provides insight into the role of competition in population declines

Oikos, Volume 2026, Issue 6, June 2026.
Competition theory suggests that interspecific prey competition can result in changes to the dietary niche, but obtaining timeseries of data from sympatric species experiencing temporal variation in competition is challenging. Scotland is an important area for two species of seals, but over the past 20 years, populations of harbour seals Phoca vitulina

Improving Living Resource Responses in Ecosystem Restoration: An Illustration Using the Chesapeake Bay

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 3, June 2026.
ABSTRACT Two key components of large‐scale ecosystem restoration planning are: (1) prioritizing individual projects based on how living resources respond, and (2) selecting and analyzing indicators of living resources to assess restoration progress and performance.

A new acoustic telemetry tag that identifies carrier mortality by monitoring activity level

Methods in Ecology and Evolution, Volume 17, Issue 6, Page 1735-1742, June 2026.
Abstract We present a new acoustic telemetry tag capable of detecting whether its carrier stops moving for long enough to presume the organism has died, and of reporting the time elapsed since movement ceased. The tag uses existing environmental sensor technology together with an algorithm with user‐specifiable thresholds, and importantly, can separate

Genetic Stock Identification Reveals Mismatches Between Management Areas and Population Genetic Structure in a Migratory Pelagic Fish

Evolutionary Applications
Sustainable fisheries management is important for the continued harvest of the world's marine resources, especially as they are increasingly challenged by a range of climatic and anthropogenic factors.

Whole‐Genome‐Sequencing Reveals Demographic History and Patterns of Parallel Adaptive Evolution in Indo‐Pacific Bottlenose Dolphins (Tursiops aduncus) Across Coastal Australian Seascapes

Molecular Ecology, Volume 35, Issue 11, June 2026.
ABSTRACT Understanding how demographic dynamics interact with environmental heterogeneity is central to explaining patterns of genomic variation in the marine realm. Indo‐Pacific bottlenose dolphins (Tursiops aduncus) occur along most of the Australian coastline, from tropical to temperate waters, encompassing pronounced differences in temperature ...

Lively Transgressions at the Urban–Ocean Edge: Conflict, Coexistence and Animals on the Move

Transactions of the Institute of British Geographers, Volume 51, Issue 2, June 2026.
Short Abstract The paper intervenes in recent debates on human–wildlife conflict and ‘Species on the Move’, drawing on cases of urban gulls in Northern Europe and sharks at Australian city beaches. The paper interrogates: representations of conflict and the interplay between media and policy; the relationship between mobility and the articulation of ...
