Going to the archives: Combining palaeoecological and contemporary data to support river restoration appraisals

River Research and Applications, Volume 41, Issue 1, Page 23-36, January 2025.
Abstract River restoration practices are being increasingly implemented to help offset the global degradation of freshwater ecosystems. The ecological success of such projects is typically determined via post‐project appraisals comparing restored conditions against specified baselines (e.g., pre‐project and/or non‐restored data), but such approaches ...

A dataset of individual wet weights of benthic macroinvertebrates

Limnology and Oceanography Letters, Volume 9, Issue 6, Page 696-715, December 2024.
Abstract Biomass estimates are crucial for modeling and understanding energy flow through ecosystems. Many modeling frameworks rely on published body weights of organisms to convert density estimates to biomass. However, published body weight data are limited to few taxa in a limited number of systems. Here we present mean individual weights for common

LIFE-HISTORY PATTERNS IN THE BROODING FRESHWATER BIVALVE PISIDIUM (SPHAERIIDAE) [PDF]

Journal Molluscan Studies, 2004
Of all freshwater molluscs, the life history of sphaeriid bivalves has been one of the best studied, partly because they brood their young. In Pisidium, one of five genera in the Sphaeriidae, offspring develop and are released synchronously and therefore the reproductive state is easily determined from collections of adults.

Invasive mussels reduce community bioturbation but do not affect oxygen penetration or nutrient fluxes in organic‐poor Great Lakes sediments

Freshwater Biology, Volume 69, Issue 11, Page 1672-1685, November 2024.
Abstract Invasive zebra and quagga (dreissenid) mussels have disrupted nutrient cycling and benthic macrofauna communities in the Laurentian Great Lakes and other invaded ecosystems. Dreissenids are now the dominant benthic macroinvertebrate in the Great Lakes, replacing the formerly dominant native bioturbating amphipod Diporeia spp.

Salamander loss alters montane stream ecosystem functioning and structure through top‐down effects

Animal Conservation, Volume 27, Issue 5, Page 722-735, October 2024.
Salamanders are seriously declining worldwide and, despite being important predators in both aquatic and terrestrial environments, their effects on freshwater ecosystems are virtually unknown. We demonstrated that salamander loss could alter montane stream ecosystem functioning and structure by reducing periphyton accrual, altering algal communities ...
