Invasive signal crayfish and native noble crayfish show trophic niche shrinkage in sympatry [PDF]
NeoBiotaStudying the coexistence of native species and invasive species with similar functional traits, habitat usage, and feeding habits is crucial for understanding the dynamics of invasion and ecological changes in the invaded ecosystem.

Environmental DNA‐based methods detect the invasion front of an advancing signal crayfish population
Environmental DNA, 2022 Aquatic invasive species, such as the signal crayfish (Pacifastacus leniusculus), present a major threat to freshwater ecosystems. However, these species can be challenging to detect in recently invaded habitats.
