Better Alone Than in Bad Company: Trophic Ecology of Co‐Occurring Invasive and Native Crayfish

open access: yesEcology and Evolution
The North American signal crayfish, Pacifastacus leniusculus, is one of the most successful invasive crayfish species in Europe. Its broad trophic niche and ability to exploit various food sources across different trophic levels, coupled with the spread ...

Effects of dietary myo-inositol on growth performance, hematological parameters, antioxidant capacity, immunity and resistance against Aeromonas hydrophila in red swamp crayfish (Procambarus clarkii)

open access: yesAquaculture Reports
The red swamp crayfish (Procambarus clarkii) is of importance in the crustacean farming of China. Myo-inositol (MI) as a vitamin-like nutrient has not been investigated in P.

Distribution, Habitat, and Life History Aspects of the Dwarf Crayfishes of the Genus Cambarellus (Decapoda: Cambaridae) in Arkansas [PDF]

open access: yes, 2019
The dwarf crayfishes of the genus Cambarellus are represented in Arkansas by only 2 species: Cambarellus (Pandicambarus) puer (Hobbs) and C. (P.) shufeldtii (Faxon). Both species are quite small and uncommonly encountered in the state.

A systematic review evaluating the performance of eDNA methods relative to conventional methods for biodiversity monitoring

open access: yesEcography, EarlyView.
The rapid adoption of environmental DNA (eDNA) methods has drastically changed biodiversity monitoring efforts. It is often claimed that eDNA methods are more sensitive and efficient than conventional biodiversity monitoring methods, but it is often unclear what metrics support this claim.

Transmission of crayfish plague [PDF]

open access: yesDiseases of Aquatic Organisms, 2002
Two possible means of transmission of crayfish plague were investigated: via fish (as vectors), and via crayfish (as hosts or vectors when dead). The crayfish transmission experiments focussed on both the viability of the fungus in dead crayfish when kept in simulated field conditions, and on the treatments which kill viable forms of Aphanomyces astaci

Presynaptic facilitation at the crayfish neuromuscular junction: Role of calcium-activated potassium conductance [PDF]

open access: yes, 1991
Membrane potential was recorded intracellularly near presynaptic terminals of the excitor axon of the crayfish opener neuromuscular junction (NMJ), while transmitter release was recorded postsynaptically.

Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...

Inventory of the Decapod Crustaceans (Crayfishes and Shrimps) of Arkansas with a Discussion of Their Habitats [PDF]

open access: yes, 1980
The freshwater decapod crustaceans of Arkansas presently consist of two species of shrimps and 51 taxa of crayfishes divided into 47 species and four subspecies. The shrimps are represented by Macrobranchium ohione and Palaemonetes kadiakensis.

Maintenance and degradation of proteins in intact and severed axons: Implications for the mechanism of long-term survival of anucleate crayfish axons [PDF]

open access: yes, 1995
Protein maintenance and degradation are examined in the severed distal (anucleate) portions of crayfish medial giant axons (MGAs), which remain viable for over 7 months following axotomy.
