Lucky To Be Alive, Luckier to Breed: Lifetime Reproduction in Weddell Seals

Ecology Letters, Volume 29, Issue 7, July 2026.
In our analysis we obtained the distribution of LRS following a theoretical and an empirical approach and compared outcomes. Our theoretical LRS distribution was strikingly similar to the empirical distribution estimated from females experiencing natural intrinsic trait variability and extrinsic environmental variability.

Deep Dark Futures: Foresighting Human Impacts on Mesopelagic Ecosystem Services

Fish and Fisheries, Volume 27, Issue 4, Page 876-894, July 2026.
This study uses foresighting to explore four plausible future scenarios of human activity affecting mesopelagic ecosystem services; provisioning, regulating, supporting and cultural. Using participatory scenario development, qualitative network modelling and indicator design, we assess systemic risks and early warning signals linked to harvest, climate

Expansion of invasive carabids across elevation and habitats on sub‐Antarctic South Georgia

Insect Conservation and Diversity, Volume 19, Issue 4, Page 812-827, July 2026.
Two introduced carabid species have continued to expand their ranges on the sub‐Antarctic island of South Georgia over the past 10–15 years. The species have colonised inland valleys and are present across habitats but are more abundant in those with high vegetation cover. N‐mixture models revealed the optimal sampling method, intensity and habitat for

Genomic Structure and Demographic History of the Brown Fur Seal: From the Ice Age to Current Isolation

Journal of Biogeography, Volume 53, Issue 7, July 2026.
ABSTRACT Aim Arctocephalus pusillus (the brown fur seal) has historically experienced population fluctuations associated with glacial cycles and anthropogenic exploitation. Previous mitochondrial DNA (mtDNA) and microsatellite analyses suggested a post‐glacial population expansion in A.

Unravelling Past Population Events in Diatoms With Genomic Based Demographic Inferences

Marine Ecology, Volume 47, Issue 4, July/August 2026.
ABSTRACT The biological productivity in the Southern Ocean is mainly driven by the abundance of phytoplankton, which changes with seasons, fluctuations in sea ice and iron as well as light availability. The distribution of biological productivity is further modulated by ocean currents.

Humpback Whale (Megaptera novaeangliae) Site Fidelity, Residency, and Movement Patterns in Ireland Based on Citizen Science Data

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Understanding the residency and movement patterns of large cetaceans like the humpback whale is crucial for effective conservation. In Ireland, the Irish Whale and Dolphin Group has been collecting humpback whale data since the 1990s, primarily through citizen science.
