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.

Distribution and dispersal of two invasive crayfish species in the Drava River basin, Croatia [PDF]
Knowledge and Management of Aquatic Ecosystems, 2009 The aim of this work is to explore the current distribution and dispersal rates of two nonindigenous crayfish species (NICS) recorded in Croatia: the signal crayfish (Pacifastacus leniusculus) and spiny-cheek crayfish(Orconectes limosus).
