Toxic oligopeptides in the cyanobacterium Planktothrix agardhii-dominated blooms and their effects on duckweed (Lemnaceae) development

open access: yesKnowledge and Management of Aquatic Ecosystems, 2018
Cyanobacterial toxins are a global threat to aquatic organisms; however, they represent only one group of bioactive cyanobacterial metabolites. Very little is known about the effects of other cyanobacterial products (e.g., non-ribosomal oligopeptides) on

Non‐native species affect the long‐term dynamics of native stream fish assemblages

open access: yesOikos, Volume 2025, Issue 8, August 2025.
Characterizing the temporal changes of biotic communities and disentangling the importance of their driving mechanisms are central themes in ecology and environmental management. Non‐native species have multiple adverse impacts on native communities and species.

The effect of epiphytic macroinvertebrates on microbial communities in different types of macrophyte-dominated shallow lakes

open access: yesKnowledge and Management of Aquatic Ecosystems, 2018
Complex interactions between epiphytic fauna and microbial food webs in periphyton are vital to the ecosystem ecology of shallow lakes. However, little is known about how different types of macrophyte dominated lakes may influence microbial and metazoan ...

Chlorination Cessation Alters Greenhouse Gas Dynamics in Artificial Urban Ponds

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 130, Issue 8, August 2025.
Abstract Cities are facing an ecological challenge, and international policies are increasingly focused on implementing nature‐based solutions to support this transition. In this context, the naturalization of artificial urban ponds (AUP) is a promising approach with proved benefits for biodiversity and human well‐being.

Marine heatwaves amplify benthic community metabolism and solute flux in a seafloor heating experiment

open access: yesFunctional Ecology, Volume 39, Issue 8, Page 1856-1868, August 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The magnitude and frequency of marine heatwaves are increasing and predicted to intensify, but our ability to understand the real‐world effects on vital benthic ecosystems is lagging behind.
