Advancing conservation breeding programs for marine invertebrates

Conservation Biology, EarlyView.
Abstract In the face of ecosystem change and biodiversity loss caused by climate change and other stressors, conservation breeding, or captive breeding, with the aim of reintroduction for wild population recovery, is an emerging tool for preventing species’ extinction and rehabilitating ecosystems.

Reproductive behaviour of the ocean triggerfish Canthidermis sufflamen (Tetraodontiformes: Balistidae) in the shallow waters of the marine‐protected area of El Hierro Island (Canary Islands)

Journal of Fish Biology, EarlyView.
Abstract The abundance of Canthidermis sufflamen has increased worldwide, including around the Canary Islands, due to global ocean warming. The reproductive behaviour of this species was studied within a marine‐protected area (MPA) and its adjacent areas off the island of El Hierro (Canary Islands).

Prospects of multipurpose biomonitoring for fisheries assessment based on environmental nucleic acids

Journal of Fish Biology, EarlyView.
Abstract Methods using environmental nucleic acids have become highly effective for monitoring aquatic biodiversity, with an array of suitable use cases, including metrics for fisheries assessment. Traditional methods for assessing fish populations often rely on invasive techniques with limited spatial and temporal coverage.

Long‐term reduction of invasive killer shrimp (Dikerogammarus villosus) density following removal of zebra mussel (Dreissena polymorpha) shells and coarse substrate on UK lake beds

Ecological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
Working with Citizen Scientists, researchers tested manual removal of coarse cobbles and zebra mussel shells from fine‐sediment lake beds to reduce invasive killer shrimp densities. Killer shrimp use these features for habitat, and after clearing them from 3 × 3 m sections of lakebed, killer shrimp densities were reduced by over 90% in these sections ...

Refugia, but Not for Everyone: Genetic Structure Differentiates Shallow and Mesophotic Populations of the Brooder Sponge Ircinia variabilis

Molecular Ecology, Volume 35, Issue 13, July 2026.
ABSTRACT Understanding how gene‐flow and selection interact across environmental gradients is essential for assessing population resilience and evaluating the deep‐refugia potential of mesophotic habitats under rapid climate change. In the context of depth, genetic connectivity patterns have been documented for broadcast‐spawning species, but that of ...
