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

open access: yesEcological 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 ...

Do solar farms alter invertebrate communities and reduce activity of the common pipistrelle bat (Pipistrellus pipistrellus) through prey‐mediated effects?

open access: yesEcological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
We investigated the effects of ground‐mounted solar photovoltaic (PV) farms on arthropod communities and tested whether changes in prey availability explain reduced bat activity. Solar farms altered arthropod community composition but did not reduce the abundance of key dipteran prey for Pipistrellus pipistrellus.

Adhesion‐Driven Removal of Microplastics From Aquatic Systems by Using Microgel Glues

open access: yesAdvanced Science, Volume 13, Issue 38, 9 July 2026.
Soft polymeric microgels function as “glues” that aggregate diverse microplastics through multivalent adhesion, promoting their interfacial deposition and co‐precipitation for efficient removal from water. Remarkably, this approach remains effective even for nanoscale plastic particles as small as 50 nm.

Effect of land use on mayfly assemblages structure in Neotropical headwater streams

open access: yesAnais da Academia Brasileira de Ciências, 2014
The aim of this study was to test the effect of agricultural and forestry land use on the structure of mayfly assemblages in low-order streams. Twenty-nine headwater streams were investigated in the state of São Paulo.
