Dysdera parthenogenetica sp. nov. (Araneae, Dysderidae): A Unique Case of Parthenogenesis in Spiders

Journal of Zoological Systematics and Evolutionary Research, Volume 2025, Issue 1, 2025.
We studied the parthenogenetic lineages of the spider Dysdera hungarica (Araneae: Dysderidae). Based on our data, we consider them to constitute a separate taxon, Dysdera parthenogenetica sp. nov. Morphologically, the new species differs mainly by slightly reduced female copulatory organs.

Morphology of the narrow-clawed crayfish (Astacus leptodactylus Eschscholtz, 1823) in the north-west Croatia [PDF]

, 2017
Astacus leptodactylus jedna je od četiri nativne vrste porodice Astacidae u Hrvatskoj, ujedno je i ključna vrsta u slatkovodnim ekosustavima. Unatoč važnosti vrste A. leptodactylus, općenito nedostaju podaci o toj vrsti na europskom nivou.

Global invasion and biosecurity risk from the online trade in ornamental crayfish

Conservation Biology, Volume 38, Issue 5, October 2024.
Abstract Trade in undomesticated ornamental animals has rapidly expanded beyond brick‐and‐mortar retail stores to now include growing numbers of internet marketplaces. The growing volume, diversity, and origins of invasive non‐native species in trade challenge already weak national biosecurity policies.

ARES(2014)2425342 - 22/07/2014. Organisation and running of a scientific workshop to complete selected invasive alien species (IAS) risk assessments [PDF]

, 2015
The introduction and spread of invasive alien species (IAS) constitutes one of the most important drivers of global change in biodiversity and ecosystem services. Robust risk assessment methods are required for IAS to provide the foundation upon which to

Assessing transgenerational gene editing capacity for enhancing aquaculture productivity in decapod crustaceans

Reviews in Aquaculture, Volume 16, Issue 4, Page 2077-2089, September 2024.
Abstract In the wake of global population increases and stagnating capture fishery production, there exists a requirement for novel biotechnologies to increase aquaculture productivity to offset demand. Through recognition of limitations imposed by aquaculture—increased incidence of disease, stress, cannibalism, and mortality in captivity—researchers ...

Mechanical excavation of wetland habitat failed to eradicate invasive American red swamp crayfish (Procambarus clarkii) in Malta

Ecological Solutions and Evidence, Volume 5, Issue 2, April/June 2024.
Invasive crayfish pose a persistent problem to freshwater ecosystems globally, and there are limited effective eradication measures. An ecological restoration project in Malta attempted to eradicate the crayfish through mechanical excavation. However three years post‐project the crayfish were abundant throughout the project site showing eradication ...
