An Integrated Framework for the Assessment of Meso‐Scale Physical Habitats in Gravel‐Bed Rivers Using Remote Sensing and 2D Hydraulic Modeling

WIREs Water, Volume 12, Issue 3, May/June 2025.
A five‐step integrated modeling framework combines remote sensing and two‐dimensional hydraulic modeling to describe mesohabitats and assess suitability for target species. Remote sensing provides a Digital Terrain Model and an orthophoto (step 1) that can be used to classify and map environmental descriptors such as substrate and refugia (step 2).

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

Freshwater 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

Integrated 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 ...

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

Biogeosciences, 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.

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

Animal 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 ...

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 ...

Variation of the stable isotope niches of native amphibians in ponds invaded by the red swamp crayfish [PDF]

NeoBiota
Relationships between native and invasive species can modify trophic interactions in food webs and the diet of native species, leading to substantial changes in their trophic niches.
