Contrasting Patterns of Genetic Variability in Pet‐Traded Red Swamp Crayfish Procambarus clarkii and Its Feral Populations

open access: yesFreshwater Biology, Volume 70, Issue 2, February 2025.
ABSTRACT The ornamental pet trade has emerged as one of the most important pathways for the introduction of non‐native aquatic species. In the last two decades, freshwater crayfish have become a popular ornamental group, with numerous non‐native populations established through this way, including some populations of the North American red swamp ...

Military activity and wetland‐dependent wildlife: A warfare ecology perspective

open access: yesIntegrated Environmental Assessment and Management, Volume 20, Issue 6, Page 2153-2161, November 2024.
Abstract Wetlands provide unique habitat functions that benefit society by provisioning food, recreation, and ecosystem sustainability. Warfare affects the habitats of wetland‐dependent reptiles, amphibians, and birds in both positive and negative ways, and opportunities exist to improve the management of wildlife habitat using a warfare ecology ...

Salamander loss alters montane stream ecosystem functioning and structure through top‐down effects

open access: yesAnimal Conservation, Volume 27, Issue 5, Page 722-735, October 2024.
Salamanders are seriously declining worldwide and, despite being important predators in both aquatic and terrestrial environments, their effects on freshwater ecosystems are virtually unknown. We demonstrated that salamander loss could alter montane stream ecosystem functioning and structure by reducing periphyton accrual, altering algal communities ...

Experimental mineralization of crustacean eggs: new implications for the fossilization of Precambrian–Cambrian embryos [PDF]

open access: yesBiogeosciences, 2012
Phosphatized globular microfossils from the Ediacaran and lower Cambrian of South China represent an impressive record of early animal evolution and development. However, their phylogenetic affinity is strongly debated.

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

open access: yesConservation 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

open access: yesAquatic 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

open access: yesReviews 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 ...

The effect of crayfish plague pathogen infection on growth of juvenile marbled crayfish Procambarus virginalis [PDF]

open access: yes, 2020
Both strong immune system and fast growth rate are important determinants of invasion success of a species and their dispersal rate in a novel environment. Since effective immune function may be costly, increased investment in immune response would limit the individual's resources available for growth, leading to a trade-off between these traits in an ...

Accounting for the power of nature: Using flume and field studies to compare the capacities of bio‐energy and fluvial energy to move surficial gravels

open access: yesEarth Surface Processes and Landforms, Volume 49, Issue 9, Page 2612-2627, July 2024.
Energy is exchanged between the ecosystem and the fluvial system. We establish that bio‐energy associated with the macroinvertebrate community is comparable in magnitude to median discharges in 11 British rivers, but is used more efficiently to move sediments than that associated with flow discharge.

Trophic role of marbled crayfish in a lentic freshwater ecosystem

open access: yesAquatic Invasions, 2019
Species’ introductions may cause severe adverse effects on freshwater ecosystems and their biota. The marbled crayfish, Procambarus virginalis Lyko, 2017, is an invasive parthenogenetically reproducing crayfish with rapid reproduction, maturation and tolerance to a wide range of environmental conditions, which was introduced to many sites across Europe
