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.

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.

When Methodological Innovation Changes the Game: A 10‐Year Review of Environmental DNA (eDNA) Applied to Crayfish

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 34, Issue 9, September 2024.
ABSTRACT The use of environmental DNA (eDNA) as a tool for monitoring represents a major innovative advance in environmental science, one that enables the detection of species without the need to observe or capture them. This article assesses the state of play of eDNA research targeting crayfish.

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 ...
