Wildfire Ash Alters Freshwater Crustacean Behavior: Disentangling the Contributions of Suspended Macroparticles and Ash‐Induced Alkalinization

Environmental Toxicology, EarlyView.
ABSTRACT Climate change and anthropogenic ignitions are intensifying wildfire frequency worldwide, elevating the risk of freshwater contamination by ash. In water, dissolved ash releases ions and other toxic constituents that increase pH and alter physicochemical conditions, while suspended ash particles may impose mechanical stress, disrupt behavior ...

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 ...

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).

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).

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.

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.

The dual role of detritus as resource and habitat: integrating non‐trophic processes to ecosystem dynamics

Oikos, Volume 2026, Issue 8, August 2026.
The diversity of ecological interactions, both trophic and non‐trophic, is central to understanding the assembly of communities. However, we have yet to study non‐trophic processes through their action on ecosystem compartments such as detritus involved in both recycling and habitat provisioning.

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
