Changes in the Immunity, Histopathology, and Metabolism of Crayfish (Procambarus clarkii) in Response to Drought

open access: yesAnimals, 2022
Freshwater ecosystems are among the most threatened ecosystems on Earth. The freshwater biodiversity crisis has caused widespread global concern. Drought as one of the factors causing freshwater biodiversity is still poorly understood.

Geological processes shaping freshwater biodiversity: a synthesis of global evidence

open access: yesBiological Reviews, EarlyView.
ABSTRACT Recent genomic data highlight the key roles of geological processes in shaping the diversification and biogeography of freshwater lineages. Specifically, physical processes such as tectonic uplift, erosion, glaciation, lake formation, and sea‐level fluctuation contribute extensively to the evolution of biotic diversity within and among ...

Flow cytometric characterization of freshwater crayfish hemocytes for the examination of physiological status in wild and captive animals [PDF]

open access: yes, 2009
Enumeration of invertebrate hemocytes is a potentially powerful tool for the determination of physiological effects of extrinsic stressors, such as hypoxia, disease, and toxicant exposure.

Monitoring a Norwegian freshwater crayfish tragedy:  eDNA snapshots of invasion, infection and extinction

open access: yesJournal of Applied Ecology, 2019
The European noble crayfish Astacus astacus is threatened by crayfish plague caused by the oomycete Aphanomyces astaci, which is spread by the invasive North American crayfish (e.g. signal crayfish Pacifastacus leniusculus).

Effect of medicinal and food homologous plants polysaccharides on animal nutrition and health: A review

open access: yesFood Biomacromolecules, EarlyView.
Abstract As one of the most important components of foods, animal meat provides a lot of protein, fat, and energy for humans. However, nutrition and health of animals directly affect the healthiness of human, especially antibiotic residues in animals induced by abuse of antibiotics.

The Effects of Intraspecific Variation of Crayfish Behavior on Nutrient Cycling in Aquatic Environments [PDF]

open access: yes, 2020
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

The continuing spread of Pacifastacus leniusculus in Carinthia (Austria) [PDF]

open access: yesKnowledge and Management of Aquatic Ecosystems, 2009
Crayfish plague and introductions of non-indigenous freshwater crayfish species (NICS) have had major consequences for the survival of autochthonous crayfish populations in Europe.

Update on the distribution of freshwater crayfish in Croatia

open access: yesKnowledge and Management of Aquatic Ecosystems, 2011
Four indigenous European and two non-indigenous American freshwater crayfish species inhabit Croatian freshwater habitats. Generally, the noble crayfish (Astacus astacus), the narrow-clawed crayfish (Astacus leptodactylus) and the stone crayfish ...
