Predation and epibiosis on egg capsules of the Shorttail fanskate, Sympterygia brevicaudata

open access: yesRevista de Biología Marina y Oceanografía, 2022
After deposition, chondrichthyan egg capsules are frequently exposed to numerous threats that affect their survival. However, the ecological factors affecting the development and survival of embryos inside egg capsules remain unclear. The aims of this study was to quantify and describe two ecological factors that affect of the Shorttail fanskate ...

Molecular responses of seaweeds to biotic interactions: A systematic review

open access: yesJournal of Phycology, Volume 60, Issue 5, Page 1036-1057, October 2024.
Abstract Seaweed farming is the single largest aquaculture commodity with >30 million tonnes produced each year. Furthermore, the restoration of lost seaweed forests is gaining significant momentum, particularly for kelps in warming temperate areas. Whether in aquaculture settings, following restoration practices, or in the wild, all seaweeds undergo ...

Systematics and character evolution of capitate hydrozoans

open access: yesCladistics, Volume 40, Issue 2, Page 107-134, April 2024.
Abstract Capitate hydrozoans are a morphologically and ecologically diverse hydrozoan suborder, currently including about 200 species. Being grouped in two clades, Corynida and Zancleida, these hydrozoans still show a number of taxonomic uncertainties at the species, genus and family levels.

Global introductions and environmental impacts of freshwater megafish

open access: yesGlobal Change Biology, Volume 30, Issue 4, April 2024.
Of the 134 extant freshwater megafish species, 46% have been introduced outside of their native ranges. Over 50% of the alien megafish species with sufficient data to evaluate the severity of their environmental impacts have caused population declines or even extirpations of native species.

A rapid assessment method to monitor the health status of habitat‐forming species in coastal benthic ecosystems

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 34, Issue 3, March 2024.
Abstract Marine habitat‐forming (MHF) species in the Mediterranean are among the most threatened coastal species by human activities. In recent decades, different stressors (e.g., warming‐induced marine heatwaves and algal blooms) have caused mass mortality events in these key species.

Global status, impacts, and management of rocky temperate mesophotic ecosystems

open access: yesConservation Biology, Volume 38, Issue 1, February 2024.
Abstract The ecology and function of rocky temperate mesophotic ecosystems (TMEs) remain poorly understood globally despite their widespread distribution. They typically occur at 20–150 m (the limit of photosynthesis), and on rocky substratum they support rich benthic communities and mobile fauna.

Genetic divergence and migration patterns of a galatheoid squat lobster highlight the need for deep‐sea conservation

open access: yesMolecular Ecology, Volume 33, Issue 1, January 2024.
Abstract Information on genetic divergence and migration patterns of vent‐ and seep‐endemic macrobenthos can help delimit biogeographical provinces and provide scientific guidelines for deep‐sea conservation under the growing threats of anthropogenic disturbances.

Parasitism and epibiosis in native and non‐native gammarids in freshwater in Ireland

open access: yesEcography, 1998
The introduced amphipod crustaceans Gammarus pulex and G. tigrinus are displacing the native G. ducheni celticus in a number of freshwater sites in Northern Ireland. We investigated parasite and epibiont infection
