Per os infectivity of white spot syndrome virus (WSSV) in white-legged shrimp (Litopenaeus vannamei) and role of peritrophic membrane [PDF]
, 2016 As earlier observations on peroral infectivity of WSSV in white-legged shrimp are conflicting, here, a standardized peroral intubation technique was used to examine (i) the role of the physical composition of the viral inoculum and (ii) the barrier ...

Ecological Solutions and Evidence, Volume 6, Issue 3, July–September 2025.This study evaluates the opportunities and challenges of using DNA metabarcoding of river macroinvertebrates for routine ecological status assessment under the EU Water Framework Directive. By reanalysing data from rivers in north‐west Spain, it identifies key sources of false positives and negatives, compares bulk and eDNA sampling with traditional ...

Impacts of the North American signal crayfish (Pacifastacus leniusculus) on European ecosystems [PDF]
Environmental Sciences Europe, 2015 As a vector of the crayfish plague (Aphanomyces astaci), invasive crayfish pose a major threat to endemic crayfish species in Europe. But do they affect whole ecosystems and fish species as well? A comprehensive review was done using online search engines on current literature to elucidate possible crayfish effects.

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 7, July 2025.ABSTRACT Amidst the rapid degradation of the environment, protected areas act as a buffer for sensitive species against drivers of change. The Kruger National Park, in the Zambezian Lowveld Freshwater Ecoregion, encompasses two critical transboundary river basins, which are threatened by overexploitation, climate change and nonnative invasive species ...

Decoupled conservatism of Grinnellian and Eltonian niches in an invasive arthropod
Ecosphere, 2010 Whether a species niche is conserved or shifts across space and time is a question of heightened interest in ecology and evolution. Considerable scientific inquiry into this topic has used invasive species to evaluate conservatism of the Grinnellian ...

Invasive crayfish impacts on native fish diet and growth vary with fish life stage [PDF]
, 2016 Assessing the impacts of invasive organisms is a major challenge in ecology. Some widespread invasive species such as crayfish are potential competitors and reciprocal predators of ecologically and recreationally important native fish species.

Proteomic profiling of the signal crayfish Pacifastacus leniusculus egg and spermatophore
Animal Reproduction Science, 2014 Proteins of the signal crayfish Pacifastacus leniusculus egg and spermatophore were identified using in-gel digestion, mass spectrometry, and Mascot search. Forty-one and one-hundred-fifty proteins were identified in egg and spermatophore, respectively.

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 7, July 2025.ABSTRACT Managing non‐native species remains a critical challenge in biodiversity conservation, highlighting the need for effective prioritisation frameworks that integrate ecological, economic and policy considerations. Given that biological invasions are a population‐level rather than a species‐level phenomenon, more nuanced assessment schemes are ...

Experimental infection of white spot syndrome virus in freshwater crayfish Pacifastacus leniusculus [PDF]
Diseases of Aquatic Organisms, 2001 The signal freshwater crayfish Pacifastacus leniusculus was found to be susceptible to infection with white spot syndrome virus (WSSV). Histopathological observations of various tissues of virus-injected crayfish showed similar symptoms to those from WSSV-infected penaeid shrimp, but no appearance of white spots on the cuticle or reddish body colour ...
