Development and Improvement of Habitat Suitability Criteria for Instream Habitat Assessments Conducted in Support of Environmental Flows in Florida

River Research and Applications, Volume 42, Issue 7, Page 1474-1499, September 2026.
ABSTRACT Florida's regulatory framework requires the establishment of minimum flows to protect aquatic ecosystems and water resources from significant harm. One of the primary methods used to evaluate significant harm is assessment of instream habitat, which relies on Habitat Suitability Criteria (HSC) curves that relate flow regimes and habitat ...

Dietary differentiation of two co‐occurring common bat species (Eptesicus nilssonii and Pipistrellus pygmaeus)

Wildlife Biology, Volume 2026, Issue 5, September 2026.
Sympatric bat species can co‐exist and avoid interspecific competition via niche differentiation e.g. diet. Detecting dietary differences can be achieved by comparing dietary niches of sympatric and allopatric populations. If dietary overlap is higher in sympatry versus allopatry, co‐occurrence may be altering the dietary niche of the species.

River Sand and Gravel Mining: Global Drivers, Impacts, and Pathways for Sustainable Management

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract River sand and gravel are mined worldwide at volumes that now rival their natural replenishment, yet quantitative knowledge of this mining activity and its consequences lags far behind many other global environmental pressures. We synthesize 411 peer‐reviewed studies published since 1974 within a new Driver‐to‐Management Pathway for ...
