Developmental, Dietary, and Geographical Impacts on Gut Microbiota of Red Swamp Crayfish (Procambarus clarkii)

Microorganisms, 2020
Red swamp crayfish (Procambarus clarkii) breeding is an important economic mainstay in Hubei province, China. However, information on the gut microbiota of the red swamp crayfish is limited. To address this issue, the effect of developmental stage, diet (

Wild boar feeding habits before versus after wolf recolonization

Journal of Zoology, EarlyView.
By analyzing wild boar diet before and after wolf recolonization in a Mediterranean coastal area, we evaluated whether the return of wolves facilitated feeding on deer carcasses by wild boar. While deer hair was never reported in samples of wild boar feces in 1991–1994, we found it in c.

Impact of noise on the behaviour and biochemical parameters of the crayfish Cherax quadricarinatus and Cherax destructor

Journal of Zoology, EarlyView.
The aim of this study was to evaluate the effect of acoustic stimulus on the behavioural and biochemical responses of two species of crayfish, Cherax destructor and Cherax quadricarinatus. Our results showed that exposure to noise significantly affects in both species motility parameters, agonistic interactions and acoustic signals emitted. In terms of

Assessing the context‐dependence of invasiveness in the Italian wall lizard (Podarcis siculus)

The Journal of Wildlife Management, Volume 90, Issue 2, February 2026.
Although the Italian wall lizard (Podarcis siculus) is widely considered fully invasive, our study on Gorgona Island shows its spread is largely confined to human‐altered habitats. Native common wall lizards (P. muralis) persist in natural areas, indicating that Italian wall lizard invasiveness is context‐dependent and mediated by human‐altered ...

First European Interlaboratory Ring Test Study to Detect DNA of Crayfish and the Crayfish Plague Pathogen From Water Samples

Environmental DNA, Volume 8, Issue 1, January–February 2026.
This European interlaboratory ring test highlights how methodological differences affect eDNA‐based detection of crayfish and the crayfish plague pathogen, emphasizing the need for harmonized protocols to improve reliability in conservation and disease monitoring efforts.

Quantitative Metabarcoding Reveals the Effects of Ecological Factors and Invasive Species on Functional Diversity of Freshwater Insects

Molecular Ecology, Volume 35, Issue 1, January 2026.
ABSTRACT Aquatic insects are the most biodiverse freshwater animals. DNA metabarcoding data are increasingly used to assess variation in insect communities, but they are rarely integrated with information on the abundance or biomass of different taxa that can provide key insights into their functional responses.

Stress Nutrition in Aquatic Animals: From Definition to Practice

Reviews in Aquaculture, Volume 18, Issue 1, January 2026.
ABSTRACT Aquaculture faces numerous challenges, with stress being one of the major issues that lead to growth loss, metabolic disorders, weakened immunity, redox imbalance, and organ damage in aquatic animals. Nutritional intervention is one of the effective strategies to address these problems. Traditional research has primarily focused on the impacts

Assessment of some trace elements accumulation in Karst lake sediment and Procambarus clarkii, in Guizhou province, China

Ecotoxicology and Environmental Safety, 2022
Lake wetland quality has decreased with the elevated concentrations of some trace elements. The consumption of crayfish in the trace elements concentrated lake wetland can be a hazard for the waterbirds and human health. Thus, the bioaccumulations of Cd,

The Substitution of Soybean Lecithin With Lysophospholipids Promoted the Growth Performance, Lipid Metabolism, and Reduced Dietary Lipid Inclusion for Pacific White Shrimp (Litopenaeus vannamei)

Aquaculture Nutrition, Volume 2026, Issue 1, 2026.
This study evaluated the feasibility of replacing soybean lecithin (SBL) with lysophospholipids (LYLs) in the diet of Pacific white shrimp, Litopenaeus vannamei. Five isonitrogenous diets were formulated as the control diet with 15 g/kg soybean oil and 15 g/kg SBL inclusion (LYL‐0), three SBL‐substituted diets with 1/3, 2/3, and 3/3 of SBL substituted ...
