Deterioration of the Littoral–Benthic Ecosystem Following Recent Expansion of Signal Crayfish (Pacifastacus leniusculus) in the World’s Clearest Large Lake

Ecosystems, 2023
Some biological invasions can result in algae blooms in the nearshore of clear lakes. We studied if an invasive crayfish ( Pacifastacus leniusculus ) modified the biomass and community composition of benthic macroinvertebrates and therefore led to a ...

Short-term effects of an environmentally relevant concentration of organic UV filters on signal crayfish Pacifastacus leniusculus.

Ecotoxicology and Environmental Safety, 2023
Personal care products, including organic UV filters, are considered emerging contaminants, with their toxic effects being a concern in recent decades. UV filters continually enter surface waters via wastewater and human activity. Despite the presence of

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

Gut microbiome alterations in the crustacean Pacifastacus leniusculus exposed to environmental concentrations of antibiotics and effects on susceptibility to bacteria challenges.

Developmental and Comparative Immunology, 2021
Gut-associated microbiota in crustaceans are recognized as a key element for maintaining homeostasis and health in the animal. Since the richness of these microbial communities is strongly influenced by the local environment, especially in aquatic ...

Diel turbidity cycles in a headwater stream: evidence of nocturnal bioturbation? [PDF]

, 2016
Purpose: A small number of recent studies have linked daily cycles in stream turbidity to nocturnal bioturbation by aquatic fauna, principally crayfish, and demonstrated this process can significantly impact upon water quality under baseflow conditions ...

Importance of proteins and mitochondrial changes as freshness indicators in fish muscle post-mortem. [PDF]

J Sci Food Agric
Abstract Evaluating protein and mitochondrial alterations post‐mortem can contribute to determining correlations between fish‐processing parameters and ultimate fish muscle quality. The myofibrillar protein alteration during rigor mortis directly affects the texture of fish muscle.

The current status of Pacifastacus leniusculus (Dana, 1852) and their effect on aquatic macroinvertebrate communities in Hungarian watercourses

Aquatic Invasions, 2022
The freshwater crayfish Pacifastacus leniusculus is among the most widespread invasive crayfish species in Europe. Pacifastacus leniusculus invaded Hungary around 1998 and here we investigated the recent expansion of this species and its impact on other ...

The effect of chronic exposure to chloridazon and its degradation product chloridazon-desphenyl on signal crayfish Pacifastacus leniusculus.

Ecotoxicology and Environmental Safety, 2021
The effects of chloridazon (Ch) and its metabolite chloridazon-desphenyl (Ch-D) at the environmentally relevant concentrations of 0.45 µg/L and 2.7 µg/L on signal crayfish Pacifastacus leniusculus were assessed in a 30-day exposure followed by a 15-day ...
