Differences in factors determining taxon‐based and trait‐based community structures: a field test using zooplankton

open access: yesLimnology and Oceanography, Volume 70, Issue 1, Page 113-127, January 2025.
Abstract Ecological community structure, which has traditionally been described in terms of taxonomic units, is driven by dispersal and environmental filters. Traits have recently been recognized as alternative units for quantifying community parameters, but they may have important differences with taxonomic units. For example, as taxon‐based community

Initial ecological recovery post‐weir removal amidst catchment‐wide improvements, in a groundwater‐dominated chalk stream

open access: yesRiver Research and Applications, Volume 41, Issue 1, Page 10-22, January 2025.
Abstract Physical habitat modification is one of the main pressures affecting river environments, impacting their ecosystem health and compromising their ability to adapt to the effects of climate change. Addressing the impacts of physical modification through reinvigorating natural processes has become a globally established river restoration ...

Comparative demography of two wild cladoceran species, Alona quadrangularis and Scapholeberis mucronata, collected in western Washington state and reared under laboratory conditions

open access: yesInvertebrate Biology, Volume 143, Issue 4, December 2024.
Abstract Populations of two cladoceran species, Alona quadrangularis and Scapholeberis mucronata, were collected from a pond in Puyallup, Washington, and reared under controlled laboratory conditions. Life tables were developed for each species under the same environmental conditions and feeding regimen to develop basic demographic data.

Diet variation of common smelt across a salinity gradient in coastal lakes on Rēkohu (Chatham Island)

open access: yesNew Zealand Journal of Marine and Freshwater Research, Volume 58, Issue 3, Page 404-421, September 2024.
ABSTRACT Sea level rise threatens ecosystem function in coastal lakes by increasing salinity and altering community composition. As mobile generalists, fish have considerable influence on the stability of a system by impacting trophic network structure.
