CRAYFISH MANAGEMENT FOR SWISS WATERS

open access: yesKnowledge and Management of Aquatic Ecosystems, 2006
Seven species of crayfish are present in Swiss waters: three native ones (Astacus astacus, Austropotamobius pallipes, Austropotamobius torrentium) and four exotic ones (Astacus leptodactylus, Orconectes limosus, Pacifastacus leniusculus, Procambarus ...

First Record of Microsporidia Infection in the Damselfly Ischnura elegans Larvae: Temperature and Predator Cue Effects on the Host’s Life History

open access: yesDiversity, 2022
Here, we report, for the first time, a microsporidian infection in laboratory-reared larvae of the damselfly Ischnura elegans. Infected larvae originated from field-collected adult females, which were caught in southern Poland in August 2020 (the second ...

Subtle ecological effects of the invasive signal crayfish (Pacifastacus leniusculus) on Iberian fish communities

open access: yesBiological Invasions
The introduction of non-native species can disrupt the structure of communities and affect the functioning of freshwater ecosystems, disturbing various taxonomic groups, including fish.

Muddied waters: suspended sediment impacts on gill structure and aerobic scope in an endangered native and an invasive freshwater crayfish [PDF]

open access: yes, 2013
Suspended sediment (SS) loadings in freshwater habitats have increased over the past century and SS is now a significant environmental stressor. Greater tolerance to environmental stressors has been proposed as a factor in the success of aquatic invasive

Environmental concentrations of sulfamethoxazole increase crayfish Pacifastacus leniusculus susceptibility to White Spot Syndrome Virus.

open access: yesFish and Shellfish Immunology, 2020
Antibiotics used for humans and livestock are emerging as pollutants in aquatic environments. However, little is known about their effect on aquatic organisms, especially in crustaceans.

ON SELECTED MORPHOMECHANICAL CHARACTERISTICS OF SIGNAL CRAYFISH (PACIFASTACUS LENIUSCULUS DANA) EGGS DURING INCUBATION

open access: yesKnowledge 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 ...

The impact of streetlights on an aquatic invasive species: artificial light at night alters signal crayfish behaviour [PDF]

open access: yes, 2016
Artificial light at night (ALAN) can significantly alter the behaviour, communication and orientation of animals, and will potentially interact with other stressors to affect biodiversity.

Invasive dynamics of the signal crayfish Pacifastacus leniusculus in a protected area

open access: yesHydrobiologia
Invasive species have been drivers of biodiversity loss and functional changes in aquatic ecosystems, including in protected areas. Therefore, monitoring population invasion dynamics and biological traits is fundamental to better understand their ...

Molecular Characterisation of Endangered White‐Clawed Crayfish Populations in Southern Switzerland

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 3, March 2026.
ABSTRACT This study investigates the phylogeography of the endangered European White‐Clawed Crayfish (WCC) Austropotamobius pallipes species complex in the main tributaries of the Po River basin in southern Switzerland and northern Italy, a diversity hotspot for this species.
