Towards Implementing Multispecies Harvest Strategies That Are Robust to Interacting Populations

open access: yesFish and Fisheries, Volume 26, Issue 5, Page 923-941, September 2025.
To advance the implementation of fisheries management that is robust to interacting populations (RIP), ecosystem management approaches can be structured using four main categories: (A) whole‐of‐ecosystem; (B) focus or key species; (C) species of conservation concern; and (D) pest or climate‐immigrant species.

Changes in the abundance and distribution of rorqual prey in the Northeast United States over four decades

open access: yesEcosphere, Volume 16, Issue 7, July 2025.
Abstract The distribution, phenology, and population dynamics of species at multiple trophic levels have been impacted by climate change across a range of spatial scales. Upper trophic level species may be uniquely impacted through changes to prey species and foraging habitats in space and time.

Environmental DNA Documents Ecosystem‐Wide Biodiversity Within the Marine Protected Area Stellwagen Bank National Marine Sanctuary

open access: yesEnvironmental DNA, Volume 7, Issue 3, May–June 2025.
Three marker genes targeting prokaryotic, eukaryotic, and vertebrate diversity were used to assess biodiversity within Stellwagen Bank National Marine Sanctuary. High levels of biodiversity were seen across the sampled area, with distinct communities across surface water, bottom water, and sediment.
