Small jellyfish, large consequences: The overlooked predatory role of hydromedusae in subtropical estuarine ecosystems

open access: yesLimnology and Oceanography, Volume 71, Issue 4, April 2026.
Abstract Hydromedusae are often overlooked in pelagic trophic ecology compared to large scyphozoans. We investigated the diet, prey selectivity, ingestion rates, digestion times, and predation impacts of the native Liriope tetraphylla and non‐indigenous species Cnidostoma fallax and Moerisia inkermanica in a subtropical estuary of the southwestern ...

Urban Pollution Promotes Biotic Simplification of the Zooplankton Community in Ponds in Northeastern Brazil

open access: yesFreshwater Biology, Volume 70, Issue 6, June 2025.
ABSTRACT Pollution significantly impacts aquatic biodiversity by limiting the species pool. However, considerable uncertainty remains regarding which community attributes should be used to demonstrate the effects of this anthropogenic disturbance. We propose that zooplankton taxonomic biodiversity could serve as a reliable pollution indicator in lentic

Lipid biomarkers reveal trophic relationships and energetic trade‐offs in contrasting phenotypes of the cold‐water coral Desmophyllum dianthus in Comau Fjord, Chile

open access: yesFunctional Ecology, Volume 38, Issue 1, Page 126-142, January 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Benthic suspension feeders like corals and sponges are important bioengineers in many marine habitats, from the shallow tropics to the depth of polar oceans. While they are generally considered opportunistic, little is known about their actual in situ diet.
