Facilitation of benthic assemblages by Bluehead Chubs: Testing the stress‐gradient hypothesis in streams

open access: yesEcology of Freshwater Fish, Volume 33, Issue 2, April 2024.
Abstract Ecosystem engineers facilitate beneficiary species by ameliorating physical habitat. The stress‐gradient hypothesis (SGH) predicts the importance of facilitation in communities should increase with physical stress but has rarely been tested in freshwater.

The effects of land‐use change on semi‐aquatic bugs (Gerromorpha, Hemiptera) in rainforest streams in Sabah, Malaysia

open access: yesFreshwater Biology, Volume 69, Issue 4, Page 556-572, April 2024.
Abstract Land‐use change and agricultural expansion have caused marked biodiversity loss in Southeast Asia, but impacts on freshwater communities have been very little studied. Semi‐aquatic bugs are abundant in streams, provide prey for many other animals, and are sensitive to environmental change, making them a relevant group for studying land‐use ...

Conservation implications of isotopic variation in nails and blood with wetland quality in three species of Australian freshwater turtle

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 34, Issue 1, January 2024.
Abstract Australian freshwater turtles are declining, reflecting global turtle trends. Understanding variation in turtle diets and habitat requirements can guide protection and restoration of ecosystems. Diet and niche overlap were investigated in three co‐existing species of turtle—the broad‐shelled turtle Chelodina expansa, the eastern long‐necked ...
