Biological invasions are increasingly recognized ecological and economic threats to biodiversity projected increase in the future. Introduced freshwater crayfish particular protruding invaders, exerting tremendous impacts on native ecosystem functioning, as exemplified by North American spiny-cheek, signal red swamp well Australian common yabby. The marbled is among most outstanding invaders due its parthenogenetic reproduction combined with early maturation high fecundity. As their...
Abstract The effects of the herbicide metazachlor and its major metabolite OA at two concentrations, including environmentally relevant concentrations (0.0115 µmol/l 0.0790 µmol/l) (0.0117 0.0805 µmol/l), respectively, were evaluated on early ontogeny, growth, behaviour, oxidative stress, antioxidant enzyme levels, histology, mortality marbled crayfish Procambarus virginalis . Both tested associated with significantly lower growth delayed ontogenetic development compared to controls....
Degradation products of herbicides, alone and in combination, may affect non-target aquatic organisms via leaching or runoff from the soil. The effects 50-day exposure primary metabolites chloroacetamide herbicide, acetochlor ESA (AE; 4 µg/L), glyphosate, aminomethylphosphonic acid (AMPA; their combination (AMPA + AE; µg/L) on mortality, growth, oxidative stress, antioxidant response, behaviour, gill histology early life stages marbled crayfish (Procambarus virginalis) were investigated....
Pharmaceutically active compounds (PhACs) are ubiquitous in the aquatic environment worldwide and considered emerging contaminants. Their effects on growth, behavior, physiological processes of organisms have been identified even at very low concentrations. Ecotoxicological investigations primarily focused single compound exposure, generally a range In natural environment, pollutants seldom occur isolation, but little is known about risks combinations chemicals. This study aimed to...
Abstract Severe weather events, such as long‐term droughts, are challenging for many freshwater species. To survive drought, crayfish tend to inhabit shelters or burrows where they can remain in contact with water high humidity environments. However, it is not known whether embryogenesis post‐embryonic development occur without free standing water. address this question, three experiments were conducted using artificial air and marbled ( Procambarus virginalis Lyko, 2017) a model Marbled...
Pharmaceutically active compounds are only partially removed from wastewaters and hence may be major contaminants of freshwaters. Direct indirect effects on aquatic organisms reported at dilute concentrations. This study was focused the possible environmentally relevant concentrations (~1 µg L−1) two psychoactive behavior freshwater crayfish. Experimental animals exposed to venlafaxine did not show any behavioral alteration. Crayfish benzodiazepine oxazepam exhibited a significant alteration...
The effects of chloridazon (Ch) and its metabolite chloridazon-desphenyl (Ch-D) at the environmentally relevant concentrations 0.45 µg/L 2.7 on signal crayfish Pacifastacus leniusculus were assessed in a 30-day exposure followed by 15-day depuration period. Locomotion, biochemical haemolymph profile, oxidative antioxidant parameters, histopathology evaluated. Crayfish exposed to Ch showed significantly (p < 0.01) higher CAT activity GSH level hepatopancreas gill compared controls....
Multisensory stimuli provide organisms with information to assess the threat present in surroundings. Olfactory cues show dominance over other sensory modalities aquatic environment. The impact of chemical predator combined experiences gained (learning) species without previous contact is not fully understood. We investigated foraging and shelter-seeking behaviour naïve experienced marbled crayfish Procambarus virginalis juveniles response signals pumpkinseed Lepomis gibbosus alone...
The round goby is an invasive fish in Europe and North America that threatens native species by predation competition. Its habitat preferences are similar to those of the European bullhead, which it displaces from shelters out-competes for available resources. We assessed microhabitat preferences, shelter use, activity bullhead single-species experiments simulator systems investigate their behavior a novel environment. Fish were video-recorded 28 h presence feed with water velocity ranging...
Methamphetamine (METH), a central nervous system stimulant used as recreational drug, is frequently found in surface waters at potentially harmful concentrations. To determine effects of long-term exposure to environmentally relevant levels on nontarget organisms, we analysed cardiac and locomotor responses signal crayfish Pacifastacus leniusculus acute stress during 21-day METH 1 μg L-1 followed by 14 days depuration. Heart rate locomotion were recorded over period 30 min before after...
