Differences in growth within and across the reproductive forms of northern crayfish (Faxonius virilis). [PDF]
Ecol Evol, 2023 Complex life histories are frequently associated with biological trade‐offs, as the use of one trait can decrease the performance of a second trait due to the need to balance competing demands to maximize fitness. Here, we examine growth patterns that are indicative of a potential trade‐off between energy allocation for body size versus chelae size ...

Otterly delicious: Spatiotemporal variation in the diet of a recovering population of Eurasian otters (Lutra lutra) revealed through DNA metabarcoding and morphological analysis of prey remains. [PDF]
Ecol Evol, 2023 Our national scale investigation of the trophic ecology of a recovering apex predator over a decade using molecular tools highlights that prey distributions are likely to drive such species recoveries. We show that the trophic interactions of otters vary over spatial, temporal, and biological gradients and that their trophic generalism has likely been ...

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

[First reporting of the signal crayfish (Decapoda, Astacidae) in the Province of Savona, Italy] [PDF]
Natural History Sciences, 2016 In this short note we report the sudden and numerically significant expansion of signal crayfish (P. leniusculus) from Piedmont towards Liguria. P. leniusculus (Decapode Astacidae) is native to northwestern America, introduced in Italy in 1981 in the ...

Les introductions de crustacés décapodes d'eau douce en France. Peut-on parler de gestion ? [PDF]
Knowledge and Management of Aquatic Ecosystems, 1997 La proportion d'espèces allochtones dans les peuplements français de crustacés décapodes d'eau douce est importante. Pour deux espèces de crevettes (famille des Atyidae) et trois espèces d'écrevisses (famille des Astacidae) autochtones, on compte quatre ...

DNA barcoding is currently unreliable for species identification in most crayfishes. [PDF]
Ecol EvolIn this paper, we assembled publicly available mitochondrial DNA (COI gene) sequence data from NCBI's nucleotide database and subsequently compared outcomes from analyses of two different types of COI dataset: one composed only of unique haplotypes for each species, and another that included redundant haplotypes.
