“…Nevertheless, it is presumed that noble crayfish populations in south-eastern Europe have maintained their original genetic structure, since this species has been of little commercial interest in the region and although diminishing, may reflect historical evolutionary and phylogenetic patterns ( Simić et al, 2008 ; Maguire, Jelić & Klobučar, 2011 ; Pârvulescu & Zaharia, 2014 ; Slavevska-Stamenković et al, 2016 ; Ðuretanović et al, 2017 ). Conversely, crayfish from south-eastern Europe (Croatia, Slovenia and Bosnia and Herzegovina) have been used for restocking of freshwaters in the central Europe that were devastated by crayfish plague in the late 19 th century (cf.…”

Background The noble crayfish (Astacus astacus) is a native European species in decline, with a contracting range and diminishing populations and abundance. Previous studies revealed this species significant genetic diversity in the south-eastern Europe, with populations from the western and the southern part of the Balkan Peninsula being the most divergent. However, sampling of populations from the western part of the Balkans was limited and insufficient for investigating genetic diversity and population divergence for the purpose of conservation planning and management. Thus, the major aim of this study was to fill in this knowledge gap by studying mitochondrial and microsatellite DNA diversity, using 413 noble crayfish from 18 populations from waterbodies in the western part of the Balkan Peninsula. Methods Phylogenetic analysis of studied populations and their mitochondrial diversity were studied using COI and 16S sequences and population genetic structure was described using 15 microsatellite loci. Results Phylogeographic analysis revealed new divergent mitochondrial haplotypes for the populations in the westernmost part of the Balkan Peninsula in the tributaries of the Sava and Drava rivers. Microsatellite data indicated that these populations harbour an important component of genetic diversity within A. astacus. The results suggest that the western part of the Balkans played an important role as microrefugia during the Pleistocene climate fluctuations, allowing the long term persistence of A. astacus populations in this region. These results will also be important to supporting conservation decision making and planning.

“…The accuracy of classi cation was low, indicating that the more individuals with similar morphological characteristics among populations (Konan et al 2010;Mavule et al 2016). Meanwhile, the higher the percentage of populations correctly classi ed, the greater the morphological differences among populations (Duretanović et al 2017). It showed that the greatest difference appeared between the Ch population and the other four populations.…”

In order to explore the breeding direction of morphological selection of Procambarus clarkii, the morphological characteristics of five P. clarkii basic populations from different regions in China were comprehensively analyzed by multivariate statistical analyses. The results showed that there were significant differences in most morphological parameters among populations and between sexes. In the discriminatory analysis, the most discriminant characteristics for distinguishing females among populations were body weight (BW), first abdominal segment width (FASW), third abdominal segment width (TASW) and third abdominal segment height (TASH), whereas for males, the characteristics were body weight (BW), carapace length (CL), carapace width (CW) and third abdominal segment width (TASW).The most significant variables of the differences between sexes were body weight (BW), third abdominal segment width (TASW) and double cheliped weight (DCW). This study would be beneficial to understanding the main morphological characteristics of P. clarkii, which could provide basic data of the collected germplasm resources and some reference for indicating the direction of P. clarkii morphology-based breeding. The germplasm resources with stronger abdomen, smaller carapace and smaller cheliped would be the selection targets, and all-female breeding would also be one of important breeding directions of for P. clarkii.

“…Research of the freshwater crayfish morphology showed that they display great morphological diversity and phenotypic plasticity due to the influence of environment and/or genetic background (Haddaway et al, 2012;Perry et al, 2013). Furthermore, studies have been focused on evaluating morphological traits based on meristic and traditional morphometric in order to study different European crayfish species (Sint et al, 2005;Maguire and Dakić, 2011;Maguire et al, 2017;Đuretanović et al, 2017), while geometric morphometric characters were used in studies of Austropotamobius torrentium (Lovrenčić et al, 2020a), A. pallipes (Scalici and Bravi, 2012), Cambarus species (Helms et al, 2015) and Procambarus clarkii (Malavé et al, 2018). The first studies on A. astacus biogeography and taxonomy were based on the analyses of morphological and meristic characteristics (Albrecht, 1983;Karaman, 1929;Karaman, 1962;Karaman, 1963).…”

“…The first studies on A. astacus biogeography and taxonomy were based on the analyses of morphological and meristic characteristics (Albrecht, 1983;Karaman, 1929;Karaman, 1962;Karaman, 1963). Later, morphometric variation among A. astacus populations was studied based on the statistical analyses of a large set of morphometric parameters per crayfish in order to define characteristics that will distinguish different populations (Sint et al, 2005;Đuretanović et al, 2017). However, traditional morphometric multivariate analyses possess a comparatively low power in describing and visualising shape variation given that variables are usually strongly correlated with size and do not encode information about the relative location of the measurements.…”

The noble crayfish (Astacus astacus), a keystone species of high ecological, economic, and cultural importance in Europe, is threatened due to a long-term population decline caused by anthropogenic pressure on its habitats, the presence of non-indigenous invasive crayfish species and climate change. Since the effective protection of the remaining populations requires conservation measures based on the comprehensive knowledge of the species, including good understanding of its genetic and morphological variability, our aim was to study morphological features of the noble crayfish in Croatia using geometric morphometrics for the first time. We applied two-dimensional geometric morphometrics to find morphological differences among 15 populations of the noble crayfish from Croatian freshwater habitats, grouped according to previously established (a) mitochondrial (genetic) lineages, (b) genetic clusters inferred from nuclear microsatellites, as well as (c) river basins and (d) habitat types (lotic, lentic). Overall, the results indicated the existence of morphological diversity among the studied populations of the noble crayfish in Croatia. Shape analysis showed differences in cephalon based on crayfish affiliation to different genetic lineages, genetic clusters, river basins and habitat types. Our study provided novel insights into morphological diversity of the endangered noble crayfish in the area of its high genetic diversity.
