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 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 ...

DNA barcoding is currently unreliable for species identification in most crayfishes. [PDF]

Ecol Evol
In 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.

Overlooked keystone species in conservation plans of fluvial ecosystems in Southeast Europe: a review of native freshwater crayfish species

Knowledge and Management of Aquatic Ecosystems, 2022
Although a large number of rivers stretches in Southeast Europe (SEE) have a pristine status compared to the rest of Europe, these ecosystems and their freshwater biodiversity are perceptibly threatened.

First record and DNA barcodes of the invasive blue-coloured spiny-cheek crayfish Faxonius limosus (Rafinesque, 1817) (Decapoda: Cambaridae)

Knowledge and Management of Aquatic Ecosystems, 2020
This contribution presents first record of a blue colour morph of spiny-cheek crayfish, Faxonius limosus (Rafinesque, 1817). Two unusually coloured individuals were caught in Poland, in two different locations, separated from each other by approximately ...

Niche dynamics along two centuries of multiple crayfish invasions

Journal of Animal Ecology, Volume 92, Issue 11, Page 2138-2150, November 2023., 2023
A historical ecology approach unveiled how the realised niche of a European crayfish species changed since 1850. In response to the introduction of two North American crayfish species, along with a lethal pathogen, its niche shrank and shifted towards more abrupt, headwater environments where the overseas invaders have not arrived.

Morphometric characteristics and condition indices of stone crayfish Austropotamobius torrentium (Shrank, 1803) from the Mlinska River [PDF]

Agroznanje, 2022
Regarded as a protected species on the IUCN list of endangered species, and classified as data deficient species, the stone crayfish (Austropotamobius torrentium) is one of the five European species from the Astacidae family that lives in freshwater ...

Assessment of listing and categorisation of animal diseases within the framework of the Animal Health Law (Regulation (EU) No 2016/429): infectious pancreatic necrosis (IPN)

EFSA Journal, Volume 21, Issue 6, June 2023., 2023
Abstract Infectious pancreatic necrosis (IPN) was assessed according to the criteria of the Animal Health Law (AHL), in particular, the criteria of Article 7 on disease profile and impacts, Article 5 on its eligibility to be listed, Annex IV for its categorisation according to disease prevention and control rules as in Article 9, and Article 8 for ...
