In search of the unexpected: the first finding of an islandic population of the noble crayfish Astacus astacus in Greece redefines its distribution

Knowledge and Management of Aquatic Ecosystems, 2022
This contribution presents the first record of the noble crayfish Astacus astacus (Linnaeus, 1758) in Euboea (Evia) Island, Greece. The crayfish was found during a fish monitoring expedition in the upper Mesapios River, in a reach that maintains flow ...

Assessing the Presence, Pattern, and Environmental Correlates of Seasonal Skin Thickening in Anurans

Integrative Zoology, EarlyView.
Histological sections, like that of the ventral pectoral skin of Lithobates pipiens, were measured to assess variation in skin thickness throughout the year in three North American anuran species. After correcting for individual body size, we test whether skin thickness changes throughout the year and which factors (environment or life history) explain

Characterisation of the Noble Crayfish Immune Response to Oomycete-Derived Immunostimulants

Fish & Shellfish Immunology
The invasive oomycete pathogen Aphanomyces astaci significantly threatens native European crayfish populations, prompting investigations towards the effects of protective immunostimulation on the immune response of the vulnerable noble crayfish (Astacus astacus).

The Effects of Noise on the Juvenile Life Stage of Crustaceans: Behavioral, Cellular, and Molecular Responses in Procambarus clarkii

Integrative Zoology, EarlyView.
Juvenile Procambarus clarkii exposed to noise exhibited behavioral changes, shifts in enzymatic activity, and altered expression of stress and immune genes. The findings highlight the sensitivity of invertebrate juveniles to anthropogenic acoustic pollution.

GENETIC DIFFERENCES AMONG NOBLE CRAYFISH (ASTACUS ASTACUS) STOCKS IN FINLAND, SWEDEN AND ESTONIA BASED ON THE ITS1 REGION

Knowledge and Management of Aquatic Ecosystems, 2006
Noble crayfish (Astacus astacus) is indigenous to Finland. The distribution of A. astacus has diminished dramatically during the past century, due to environmental changes, crayfish plague (Aphanomyces astaci) outbreaks and stocking of alien signal ...

ANNUAL ACTIVITY OF THE NOBLE CRAYFISH (ASTACUS ASTACUS) IN THE ORLJAVA RIVER (CROATIA) [PDF]

Bulletin Français de la Pêche et de la Pisciculture, 2006
We studied the annual activity of the noble crayfish (Astacus astacus) at three sites along the Orljava River, in the continental part of Croatia, between August 2003 and September 2004. Each site represented the typical characteristics of the upper, middle and lower section of the river (5, 30 and 50 km from the spring, respectively).

Blue plaque review series: Thomas Graham Brown: Before his time

Experimental Physiology, EarlyView.
Abstract Thomas Graham Brown made a seminal discovery, published in 1911 while he was a Carnegie Fellow in the University of Liverpool laboratory of Nobel Prize winner Charles S. Sherrington. Working in cats, he showed that rhythmic ‘voluntary’ behaviour, such as stepping and, by inference, walking, does not result from a chain of reflex events, but ...

Differing virulence of Aphanomyces astaci isolates and elevated resistance of noble crayfish Astacus astacus against crayfish plague [PDF]

Diseases of Aquatic Organisms, 2012
Crayfish plague epidemics (caused by Aphanomyces astaci) have been causing population collapses among native European crayfish stocks since the late 1800s. Recent indirect and direct evidence has shown that its virulence has been variable, with native European crayfish even acting as carriers. We tested the differences in A.

Worldwide Invasions of Centrarchidae: The Dark Side of the Sunfish Family

Fish and Fisheries, Volume 27, Issue 4, Page 781-812, July 2026.
ABSTRACT Freshwater fish invasions are major drivers of global ecological change, disrupting native biodiversity and ecosystem functions. However, many invasive fish hold significant socioeconomic value, resulting in conflict over their management. Centrarchidae, which are globally distributed and are important for sportfishing and aquaculture, are now
