Microplastic burden in invasive signal crayfish (Pacifastacus leniusculus) increases along a stream urbanization gradient [PDF]
Ecology and Evolution, 2023 Microplastics are a globally pervasive pollutant with the potential to directly impact species and accumulate in ecosystems. However, there remains a relative paucity of research addressing their accumulation in freshwater ecosystems and a near absence ...

eDNA-based detection of the invasive crayfish Pacifastacus leniusculus in streams with a LAMP assay using dependent replicates to gain higher sensitivity [PDF]
Scientific Reports, 2022 LAMP assays are becoming increasingly popular in the field of invasive species detection but are still underused in eDNA-based monitoring. Here, we propose a LAMP assay designed to detect the North American crayfish species Pacifastacus leniusculus in ...

Differential elemental accumulation of the signal crayfish (Pacifastacus leniusculus) along an invasion gradient [PDF]
NeoBiotaThe non-native signal crayfish (Pacifastacus leniusculus) can influence elemental cycling in aquatic ecosystems through bioaccumulation and transfer of chemical elements, with potential spatial variation along invasion gradients.

Dispersal and coexistence of two non-native crayfish species (Pacifastacus leniusculus and Procambarus clarkii) in NE Portugal over a 10-year period [PDF]
Knowledge and Management of Aquatic Ecosystems, 2011 NE Portugal is one of the most isolated and low populated regions of Western Europe. Recently, two American crayfish species reached this area: signal crayfish Pacifastacus leniusculus coming from Spain and red swamp crayfish Procambarus clarkii in its ...

ON SELECTED MORPHOMECHANICAL CHARACTERISTICS OF SIGNAL CRAYFISH (PACIFASTACUS LENIUSCULUS DANA) EGGS DURING INCUBATION [PDF]
Knowledge and Management of Aquatic Ecosystems, 2004 Changes in resistance to mechanical pressure during embryogenesis were studied in the signal crayfish (Pacifastacus leniusculus Dana). A constant increase in egg size (volume and surface area) was observed to take place throughout the embryonic ...
