The first record of translocated white-clawed crayfish from the Austropotamobius pallipes complex in Sardinia (Italy)

Journal of Limnology, 2015
The white-clawed crayfish Austropotamobius pallipes complex is native to Europe, being present in 18 European countries, Italy included. However, the number and abundance of its populations are today restricted and it has been recently classified as ...

N-Nitrosodimethylamine as an Emerging Environmental Contaminant: Sources, Analytical Advances, and Ecotoxicological and Human Health Risks. [PDF]

Int J Anal Chem
Over the last few years, N‐nitrosodimethylamine (NDMA) has become a significant environmental contaminant with both anthropogenic and natural sources. The alarming profile of it can be explained by the fact that it is a genotoxic substance and easily spreads through the atmospheric and water systems. The production of NDMA takes place through a variety

Better Alone Than in Bad Company: Trophic Ecology of Co-Occurring Invasive and Native Crayfish. [PDF]

Ecol Evol
This study investigated and compared trophic interactions between invasive signal crayfish and native white‐clawed crayfish at sites of co‐occurrence and in allopatry. The presence of crayfish plague, body condition, and trophic niche traits were explored as possible factors that make invasive signal crayfish a strong competitor, enhancing its ...

Evaluation of the pollution pressures posed by groups of chemicals on British riverine invertebrate populations. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT Globally, rivers receive a diverse range of chemicals, including metals, pesticides, persistent organic pollutants, petrochemicals, human and veterinary pharmaceuticals and personal care products. However, the extent to which these different chemical groups affect riverine invertebrate communities is not well defined.

Water chemistry and endangered white-clawed crayfish: A literature review and field study of water chemistry association in Austropotamobius pallipes [PDF]

, 2015
Populations of the endangered white-clawed crayfish (Austropotamobius pallipes) have rapidly declined in distribution and density in recent decades as a result of invasive crayfish, disease and habitat degradation.

Procambarus virginalis Lyko, 2017: A new threat to Iberian inland waters. [PDF]

Ecol Evol
We provide the first record of Procambarus virginalis in the Iberian Peninsula, based on morphological and genetic evidence (molecular barcoding of COI). We discuss its most plausible introduction pathways, update its global geographical distribution, highlight the potential impacts if it becomes invasive in Iberia and recommend some proposal ...

Placement matters: Implications of trail- versus random-based camera-trap deployment for monitoring mammal communities. [PDF]

Ecol Appl
Abstract Optimizing protocols to assess and monitor mammal communities is essential to meet the current biodiversity targets of halting species loss. Camera‐traps are the most effective tool for multispecies monitoring, yet their deployment strategy is debated, with two main strategies adopted: trail‐ and random‐based camera deployment.

Influence of distance from source population and seasonality in eDNA detection of white‐clawed crayfish, through qPCR and ddPCR assays

Environmental DNA, 2023
The white‐clawed crayfish (Austropotamobius pallipes) is an emblematic taxon of European rivers, found mainly in oxygenated streams, known to be an excellent indicator of river quality. Since several decades, the population of A.

Dispersal and coexistence of two non-native crayfish species (Pacifastacus leniusculus and Procambarus clarkii ) in NE Portugal over a 10-year period [PDF]

, 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 ...
