Relationships among tissues, biofluids, and otolith selenium concentrations in wild female burbot (Lota lota)

open access: yesIntegrated Environmental Assessment and Management, EarlyView., 2023
Abstract In the Lake Koocanusa‐Kootenai River system (Montana, USA and British Columbia, Canada), selenium (Se) contamination has become an international concern and is suspected to contribute to the observed burbot (Lota lota) population collapse. Due to our limited ability to sample burbot in Lake Koocanusa for monitoring studies, we used a reference

Addressing climate change and development pressures in an urban estuary through habitat restoration planning

open access: yesFrontiers in Ecology and Evolution, 2023
Native habitats in Florida face dual pressures at the land-sea interface from urban development and sea-level rise. To address these pressures, restoration practitioners require robust tools that identify reasonable goals given historical land use trends,
