Predatory functional response and prey choice identify predation differences between native/invasive and parasitised/unparasitised crayfish. [PDF]

PLoS ONE, 2012
BACKGROUND: Invasive predators may change the structure of invaded communities through predation and competition with native species. In Europe, the invasive signal crayfish Pacifastacus leniusculus is excluding the native white clawed crayfish ...

Drivers Behind Spatiotemporal Variation in Environmental DNA: An Assessment Using a Rare Aquatic Salamander, the Eastern Hellbender (Cryptobranchus alleganiensis alleganiensis)

Environmental DNA, Volume 7, Issue 6, November–December 2025.
We examined the seasonal and fine‐scale spatial variability of eDNA in situ for a rare aquatic salamander, the Eastern Hellbender (Cryptobranchus alleganiensis alleganiensis), and identified physical and hydrological stream characteristics that impact both eDNA concentration estimates and detection rates.

Extending sampling approaches for great crested newt (Triturus cristatus) eDNA monitoring

Ecological Solutions and Evidence, Volume 6, Issue 4, October–December 2025.
Environmental DNA (eDNA) monitoring has been used for great crested newt (Triturus cristatus) survey in the UK since the publication of a Defra‐funded trial in 2014 and approval of a regulated protocol. Our study provides evidence that changes to this protocol, including use of filtration for eDNA capture and permitting eDNA surveys in July and August,

Fast‐tracking species at risk conservation: A framework for addressing recovery actions through multi‐agency collaboration

Ecological Solutions and Evidence, Volume 6, Issue 4, October–December 2025.
Queensnake as a rally‐point for species‐at‐risk conservation. Abstract A major challenge in conservation biology is to prevent the loss of species and communities that are critical to biodiversity on Earth. One of the tools governing bodies have to ameliorate the loss of species is through Species at Risk legislation.

MANAGING AN ABUNDANT CRAYFISH RESOURCE FOR CONSERVATION -A. PALLIPES IN IRELAND

Knowledge and Management of Aquatic Ecosystems, 2002
Irish white-clawed crayfish stocks show high genetic uniformity between systems, although individual populations usually show good heterozygosity. The inference is that they were derived from a single immigrating stock, related to those in Western France.

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 ...

MINIMISING LOSS OF CRAYFISH AND HABITATDURING WORKS ON WATERCOURSES

Knowledge and Management of Aquatic Ecosystems, 2003
Works in watercourses with white-clawed crayfish Austropotamobius pallipes cause temporary or permanent loss of habitat and crayfish. Past modifications can also leave waterbodies unfavourable for crayfish, but sometimes there is scope to improve them ...

STATUS OF AUSTROPOTAMOBIUS PALLIPES COMPLEX IN THE WATERCOURSES OF THE ALESSANDRIA PROVINCE (N-W ITALY)

Knowledge and Management of Aquatic Ecosystems, 2005
Information was gathered on the distribution of white-clawed crayfish Austropotamobius pallipes complex in the watercourses of the Alessandria province (NW Italy), on the biological and ecological preferences of the species, and on the features of the ...
