Transglutaminase inhibition stimulates hematopoiesis and reduces aggressive behavior of crayfish, Pacifastacus leniusculus. [PDF]

J Biol Chem, 2019
Transglutaminase (TGase) is a Ca2+-dependent cross-linking enzyme, which has both enzymatic and nonenzymatic properties. TGase is involved in several cellular activities, including adhesion, migration, survival, apoptosis, and extracellular matrix (ECM) organization. In this study, we focused on the role of the TGase enzyme in controlling hematopoiesis

Phylogenetic species delimitation for crayfishes of the genus Pacifastacus [PDF]

PeerJ, 2016
Molecular genetic approaches are playing an increasing role in conservation science by identifying biodiversity that may not be evident by morphology-based taxonomy and systematics.

Modulation of endogenous antioxidants by zinc and copper in signal crayfish (Pacifastacus leniusculus). [PDF]

Chemosphere, 2021
Metal pollution is a long-standing concern and bioindicators are commonly used in ecotoxicological studies to monitor impacted wildlife populations for evidence of sublethal effects. Significant variation in the response of common biomarkers to metals is reported across taxa, thus necessitating careful characterization in model organisms. In this study,

Impacts of the North American signal crayfish (Pacifastacus leniusculus) on European ecosystems. [PDF]

Environ Sci Eur, 2015
As a vector of the crayfish plague (Aphanomyces astaci), invasive crayfish pose a major threat to endemic crayfish species in Europe. But do they affect whole ecosystems and fish species as well? A comprehensive review was done using online search engines on current literature to elucidate possible crayfish effects.

The hematopoietic tissue of the freshwater crayfish, Pacifastacus leniusculus: organization and expression analysis. [PDF]

Cell Tissue Res
Abstract The hematopoietic tissue (HPT) and anterior proliferation center (APC) are the main hemocyte-producing organs of the freshwater crayfish, Pacifastacus leniusculus. To deepen our understanding of immune responses to various pathogens, it is essential to identify distinct hemocyte subpopulations with specific functions and to further ...

Better Alone Than in Bad Company: Trophic Ecology of Co-Occurring Invasive and Native Crayfish. [PDF]

Ecol Evol
This study investigated and compared trophic interactions between invasive signal crayfish and native white‐clawed crayfish at sites of co‐occurrence and in allopatry. The presence of crayfish plague, body condition, and trophic niche traits were explored as possible factors that make invasive signal crayfish a strong competitor, enhancing its ...

Nikkelin kertyminen täplärapuun (Pacifastacus leniusculus) kahdessa eri lämpötilassa

, 2017
Nickel accumulation in signal crayfish (Pacifastacus leniusculus) at two different temperatures. Metal emissions caused by industrial mining activities are a world-wide environmental problem. In these emissions metals are often in the form of sulfide or chloride which are readily bioavailable to biota.

Observation of museum specimens of the genus Pacifastacus Bott, 1950 (Decapoda: Astacidae)

Nauplius, 2018
Until recently, three subspecies had traditionally been recognized in the astacid species Pacifastacus leniusculus (Dana, 1852): Pacifastacus leniusculus leniusculus, Pacifastacus leniusculus klamathensis (Stimpson, 1857), and Pacifastacus leniusculus ...

Competition and parasitism in the native White Clawed Crayfish Austropotamobius pallipes and the invasive Signal Crayfish Pacifastacus leniusculus in the UK [PDF]

, 2009
Many crayfish species have been introduced to novel habitats worldwide, often threatening extinction of native species. Here we investigate competitive interactions and parasite infections in the native Austropotamobius pallipes and the invasive ...
