“…The calculated LC10 values were divided by 2 between 24h (1128 ppm) and 96h (585 ppm) of exposure. Similar observations were highlighted after a 14-days chronic exposure with a LC50 divided by 10 between 1 and 14 days (Benítez-Mora et al, 2014). Camargo et al (2005) concluded that LC measured values may be divided by a factor 18 to 20 between acute and chronic exposures.…”

“…In the current study, we show that elevated nitrate concentration slows the reaction time and foraging efficacy of non-native crayfish species. A previous studyBenítez- Mora et al (2014) showed a similar effect of nitrate on native European crayfish (A. pallipes) foraging efficacy. Crayfish have chemosensory hairs within their ambulatory feet(Fedotov 2009) and slower reactions to prey at higher nitrate concentrations suggests that nitrate can interfere with the sensitivity of crayfish to chemical cues from prey.…”

“…Points with shared letters denote non-significant differences (P > 0.05)DiscussionThis experimental study has shown that nitrate, even at levels deemed safe for use as drinking water (Council of the European Union 1998), can reduce the foraging efficacy of aquatic nonnative species in the UK. The effects of high nitrate are generally not lethal to crayfish; in fact, they appear to be relatively tolerant compared to other aquatic organisms(Jensen 1996;Benítez-Mora et al 2014). However, the current study has shown that elevated nitrate may alter the predatory impact of crayfish on other organisms, a key trait that makes non-native crayfish particularly troublesome invaders.…”

Environmental nitrate impacts foraging and agonistic behaviours of invasive non-native crayfish (Pacifastacus leniusculus and Faxonius virilis)

Life history traits such as predation and foraging are key behavioural mechanisms through which invasive, non-native species can have a detrimental effect on the resident flora and fauna of recipient ecosystems. Environmental change may alter these traits in ways that are currently poorly understood. In aquatic ecosystems, changes to the environment such as nitrate pollution can have chronic, unforeseen consequences for both native and invasive species. As keystone species and ecosystem engineers, non-native crayfish species can be highly destructive through predating on native species from multiple trophic levels. Here, we assessed the effect of nitrate concentration on the foraging behaviour of two invasive crayfish species from the UK (Pacifastacus leniusculus and Orconectes virilis), particularly focussing on whether there were any species-specific effects of nitrate. During experimental trials, elevated nitrate concentration had a similar impact on the foraging efficacy of both P. leniusculus and O. virilis, slowing both their initial reaction and latency to feed. Nitrate also reduced the ability of both crayfish species to catch live prey as well as the total number of prey consumed. Though both species were similarly influenced by nitrate, we highlight that even at levels deemed safe for drinking water (50 mg NO3 -/L), nitrate concentration can significantly impact the behavioural traits of aquatic species. In the case of invasive species, fluctuations in environmental nitrate concentration could therefore have implications for invader success and impacts on the wider ecosystem.

“…In parallel with the use of biochemical and physiological stress parameters as biomarkers of anthropogenic pollution, recently many authors suggested the detection of changes in behavioral traits as a useful diagnostic tool and a reliable early-warning biomarker (Amaral et al 2009;Bartolini et al 2009;Culbertson et al 2007;Johnson and White 2009). For example, crayfish Austropotamobius italicus exposed to nitrate showed a mortality increase as a result of the decrease in their escape response and food consumption (Benítez-Mora et al 2014). It is evident that food consumption is an important endpoint because a negative change in this behavioral response can decrease the survival chance of affected animals as suggested by authors.…”

The present study analyzes a battery of biomarkers in the water bug Belostoma elegans from a stream polluted with organic matter (OMS), and another one considered as reference site (RS) during spring-summer season (December to March). Biochemical parameters of glucidic, lipidic and oxidative metabolic pathways were analyzed in males and females of this insect. In general, no significant differences were observed in all biomarkers assayed between both sexes, except lactate concentration which was higher in males than in females (p < 0.0006) in the first three months. About carbohydrate metabolism parameters, only pyruvate-kinase showed significant differences between insects collected in both streams (p < 0.05) during December. However, the total lipid content, saturated fatty acid, and mainly triacylglycerol were higher in insects from RS compared to those from OMS (p < 0.002) in all sampled months. Levels of lipoperoxidation, protein oxidation, reduced glutathione and glutathione-S-transferase activity showed no differences between insects collected from both streams. Nevertheless, the significant increase observed in superoxide dismutase and catalase activities (p < 0.004) could be due to the elevated oxidative metabolism in insects from RS compared to those from OMS with lower dissolved oxygen. Regarding those responding parameters, males accounted for the differences between the two sites during the study period. In conclusion, our results support that lipidic energetic reserves and antioxidant enzyme activities in B. elegans could be used as biomarkers of environmental pollution by organic matter.
