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

Hydrobiologia
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 ...

Host shift to non-native species or ecological dead end? Endangered branchiobdellidans (Annelida: Clitellata) found on introduced Signal Crayfish in Japan

Knowledge and Management of Aquatic Ecosystems
Symbionts, including parasites, are usually small and thus have been overlooked for their existence and scientific research. In the context of biological invasion, host shifts between native and non-native species occur. Since symbionts often affect host

A STUDY ON THE POSSIBLE EFFECT OF TWO CRAYFISH SPECIES ON EPILITHIC ALGAE IN A MOUNTAIN STREAM FROM CENTRAL SPAIN

Knowledge and Management of Aquatic Ecosystems, 2006
The effects on epilithic algae of increasing densities of two crayfish species, Austropotamobius italicus and Pacifastacus leniusculus, the latter recently introduced in Spain, have been monitored using riverine enclosures, within a large experimental ...

The home range of the signal crayfish in a British lowland river [PDF]

, 1997
The signal crayfish Pacifastacus leniusculus (Dana), a native of north-western North America, is now a common resident in some British fresh waters following its introduction to England in 1976 (Lowery & Holdich 1988).

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

Biological 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 ...

RELATIONSHIPS BETWEEN CHANGES IN HABITAT CONDITIONS AND POPULATION DENSITY OF AN INTRODUCED POPULATION OF SIGNAL CRAYFISH (PACIFASTACUS LENIUSCULUS IN A FLUVIAL SYSTEM.

Knowledge and Management of Aquatic Ecosystems, 2001
After the disappearance of the native crayfish in many rivers in Biscay, Basque Country, Spain, the signal crayfish Pacifastacus leniusculus was introduced in the main fluvial stretches and several breeding populations have established.

The mycobiome of a successful crayfish invader and its changes along the environmental gradient

Animal Microbiome, 2023
Background The microbiome plays an important role in biological invasions, since it affects various interactions between host and environment. However, most studies focus on the bacteriome, insufficiently addressing other components of the microbiome ...

Design and Validation of a Single‐Species Environmental DNA qPCR Assay for the Detection of the Invasive Chinese Mitten Crab Eriocheir sinensis

Environmental DNA, Volume 7, Issue 5, September–October 2025.
The Chinese mitten crab (Eriocheir sinensis) is considered amongst the most damaging invasive species globally; however, the UK distribution of the species is not well known, with current management protocols reliant on reports of individual sightings. In this study, the first probe‐based, species‐specific qPCR assay was developed for the detection of ...
