Prohibiting pet crayfish does not consistently reduce their availability online
The pet trade is a significant source of introductions of non-indigenous aquatic species, such as crayfish. To test whether legislation that regulates the ownership of ornamental animals for aquariums had the desired effect of reducing the availability ...

Probable Displacement of Riffle-Dwelling Invertebrates by the Introduced Rusty Crayfish, \u3ci\u3eOrconectes Rusticus\u3c/i\u3e (Decapoda: Cambaridae) in a North-Central Wisconsin Stream [PDF]
The rapid northward range expansion of the rusty crayfish, Orconectes rusticus, and its negative effects on Wisconsin lakes have been the subjects of intense study throughout the last fifteen years.

Invasive alien crayfish pose significant threats to biodiversity in aquatic ecosystems. In isolated water bodies they impact local amphibian populations by predation, and altering water quality due to burrowing behaviour.

Abstract With the development of dental microwear texture analysis (DMTA), there has been an increasing application of DMTA for dietary estimation in extant and fossil reptiles, including dinosaurs. While numerous feeding experiments exist for herbivorous mammals, knowledge remains limited for carnivorous reptiles. This study aimed to qualitatively and

The Effects of Intraspecific Variation of Crayfish Behavior on Nutrient Cycling in Aquatic Environments [PDF]
Human activities are rapidly altering species traits at a global scale. Yet, there remains a critical need to determine whether trait variation within species affects ecosystem responses to global change. In particular, intraspecific variation in feeding

ABSTRACT The archaeological site Graman B4 provided one of the first records of substantial dietary change in ancient Australian Aboriginal society. Initial examination of the faunal remains from this site suggested that Late Holocene hunters reduced their focus on high‐ranked kangaroos to increasingly rely on arboreal possums; and that these ...

Physiological Responses to Acute Silver Exposure in the Freshwater Crayfish (\u3cem\u3eCambarus diogenes diogenes\u3c/em\u3e)—A Model Invertebrate? [PDF]
Adult crayfish (Cambarus diogenes diogenes) exposed to 8.41 ± 0.17 μg silver/L (19.4% as Ag+) in moderately hard freshwater under flow-through conditions for 96 h exhibited ionoregulatory disturbance, elevated metabolic ammonia (Tamm) production and ...
