Unraveling multipredator impacts in salmon‐bearing rivers using quantitative DNA metabarcoding

open access: yesEcological Applications, Volume 35, Issue 8, December 2025.
Abstract Ecological impacts of invasive species are mounting as their numbers and geographic extent continue to increase. Across extensive parts of their range, Pacific salmon (Oncorhynchus spp.) smolts face an expanding gauntlet of nonnative predators during their seaward migration.

Transglutaminase 1 and 2 are localized in different blood cells in the freshwater crayfish Pacifastacus leniusculus.

open access: yesFish and Shellfish Immunology, 2020
In the present study we show that hemocytes in the freshwater crayfish Pacifastacus leniusculus express two different transglutaminases. We describe the sequence of a previously unknown TGase (Pl_TGase1) and named this as Pl_TGase2 and compared this ...

Biological invasions: a global assessment of geographic distributions, long‐term trends, and data gaps

open access: yesBiological Reviews, Volume 100, Issue 6, Page 2542-2583, December 2025.
ABSTRACT Biological invasions are one of the major drivers of biodiversity decline and have been shown to have far‐reaching consequences for society and the economy. Preventing the introduction and spread of alien species represents the most effective solution to reducing their impacts on nature and human well‐being.

Environmental DNA as a tool for hydropower impact assessments: current status, special considerations, and future integration

open access: yesBiological Reviews, Volume 100, Issue 6, Page 2584-2607, December 2025.
ABSTRACT Globally there is an urgent need to find sustainable solutions to balance energy production with the protection of vulnerable species and conservation of biodiversity. This is particularly critical for freshwater ecosystems, habitats, and species that may be impacted by hydropower development and operations needed to meet energy grid demands ...
