The spread of non‐native species
ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.

Phylogenetically‐Informed Crayfish Conservation in the Face of Climate Change
Crayfish are a vital part of freshwater ecosystems, yet one third of assessed species are threatened with extinction, and almost 90% are highly sensitive to climate change. In this study, we produced a phylogenetically‐informed species prioritisation for crayfish conservation and explored the impacts of projected climate change scenarios on crayfish ...

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

Through progressive flume experiments, this study demonstrated that increased bed shear stresses corresponded with increased cohesive fine sediment (<62‐μm) remobilisation depths from a representative chalk stream gravel bed. This represents some of the first scientifically robust data, which can direct revised and targeted fine sediment management in ...

Distribution and biometry of native and alien crayfish in Trentino (Italian Alps)
To fill the existing gaps in the knowledge of the crayfish species distribution in Trentino region (North-East Italy), we surveyed fourteen lakes, six ponds and sixty-nine creeks and streams in 2010-2012.

Impacts of signal crayfish on stream fishes [PDF]
Invasive species cause biodiversity and economic loss globally. Invasive crayfish have a wide range of effects as a result of their high densities and biomass, feeding at multiple trophic levels, aggressive competition for shelter and ecosystem ...

Recent changes in distribution pattern of freshwater crayfish in Croatia − threats and perspectives
Analysis of Croatian freshwater crayfish populations, aiming to gather new distributional data and complement previous surveys (2005–2011), was performed during 2014–2016, within the frame of Natura 2000 Integration Project.

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