Invasive non-native species represent a leading threat to global freshwater biodiversity and crayfish frequently cause extensive ecological damage. However, the extent which their impact: (1) depends on invader identity (2) differs from natural state with native remains unclear. Comparison of functional responses invasive represents promising approach in this regard. Here, we explored whether f...

One of the most critical challenges in species distribution modelling is testing and validating various digitally derived environmental predictors (e.g., remote-sensing variables, topographic variables) by field data. Therefore, here we aimed to explore value soil properties spatial four European indigenous crayfish species. A database with 473 presence absence locations Romania for Austropotam...

Abstract In this study, the hemolymph vascular system (HVS) in two cambarid crayfishes, i.e. Marbled Crayfish, Procambarus virginalis Lyko, 2017 and Spiny Cheek Faxonius limosus (Rafinesque, 1817), is investigated regard of areas non-genetic phenotypic variation. Despite their genetic identity, specimens P. show variability certain features HVS. Thus, we describe varying branching patterns, spo...

Crayfish (A. astacus) stretch receptors are an example of invertebrate muscle stretch receptors. They show strong homology to mammalian muscle spindles and bi-polar neurons in D. melanogaster, which are typical, non-ciliated, multi-dendritic, afferent neurons. Such receptors are observed in many species and perform an important sensory role. However, they are poorly characterised. A previous bi...
