Phylogeographic patterns of genetic diversity in Pontastacus leptodactylus (Decapoda: Astacidae): is the hypothesis of the taxonomically rich genus Pontastacus true?

open access: yesZoological Journal of the Linnean Society, 2023
Abstract The narrow-clawed crayfish Pontastacus leptodactylus is a large native European astacid crayfish species distributed in the drainage area of the Azov, Black and Caspian Seas. The species shows immense morphological diversity across its range. Various species and subspecies have been described and, recently, eight species and two

Influence of distance from source population and seasonality in eDNA detection of white‐clawed crayfish, through qPCR and ddPCR assays

open access: yesEnvironmental DNA, Volume 5, Issue 4, Page 733-749, July 2023., 2023
Abstract The white‐clawed crayfish (Austropotamobius pallipes) is an emblematic taxon of European rivers, found mainly in oxygenated streams, known to be an excellent indicator of river quality. Since several decades, the population of A. pallipes declined in relation to anthropogenic pressure, habitat loss, and competition with pests (invasive ...

Natural Biota’s Contribution to Cultured Aquatic Animals’ Growth in Aquaculture Cannot Be Ignored

open access: yesAquaculture Research, Volume 2023, Issue 1, 2023., 2023
The rapid expansion of the aquaculture industry is accompanied by high organic and nutrient loadings from formulated feeds. This leads to water deterioration and pathogenic microorganisms. Natural biota (e.g., bacteria, phytoplankton, zooplankton, and zoobenthos) in ponds form important parts of cultured aquatic animals’ diets.

Cytology, function and dynamics of stem and progenitor cells in decapod crustaceans

open access: yesBiological Reviews, Volume 97, Issue 2, Page 817-850, April 2022., 2022
ABSTRACT Stem cells play key roles in development, tissue homeostasis, regeneration, ageing and diseases. Comprehensive reviews on stem cells are available for the determinately growing mammals and insects and some lower invertebrates like hydra but are rare for larger, indeterminately growing invertebrates that can live for many decades.
