Adding large woody material into a headwater stream has immediate benefits for macroinvertebrate community structure and function

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 31, Issue 4, Page 930-947, April 2021., 2021
Abstract Hydromorphological rehabilitation through installing large woody material (LWM) is increasingly being used to reverse degradation of stream ecosystems. There have been many criticisms of stream rehabilitation projects, because many have not met their goals and many others have not been monitored well enough to assess whether their goals were ...

Strong impacts of signal crayfish invasion on upland stream fish and invertebrate communities

open access: yesFreshwater Biology, Volume 66, Issue 2, Page 223-240, February 2021., 2021
Abstract Impacts of invasive signal crayfish Pacifastacus leniusculus on native species and ecosystems are widely recognised, but mostly through small‐scale studies and laboratory experiments that may not always reflect impacts in nature. Recorded effects of signal crayfish on fish populations are equivocal.
