TL;DR: This work uses metabarcoding of two markers of different lengths, derived from an annual time series of aqueous lake eDNA, to examine temporal shifts in ecosystem biodiversity and in an ecologically important group of macroinvertebrates

TL;DR: The results indicate that the per capita functional response difference between the species may contribute to success of the invader and extinction of the native species, as well as decreased biodiversity and biomass in invaded rivers.

TL;DR: Overall, mitogenomic sequencing yielded more informative predictions of biomass content from bulk macroinvertebrate communities than metabarcoding, but for large‐scale ecological studies, metabarcode currently remains the most commonly used approach for diversity assessment.

TL;DR: The high prevalence of microsporidian parasites and occurrence of shared T. contejeani infection lead us to propose that future studies should consider the impact of these parasites on native and invasive host fitness and their potential effects upon the dynamics of native-invader systems.

TL;DR: Evidence for phenotypic plasticity suggests that crayfish are resilient to relocation, and that they can adapt morphologically to novel environmental conditions, and may prove a useful technique in the conservation of white-clawed cray fish populations within the UK.
