Although the noble crayfish (Astacus astacus L.) and stone crayfish (Austropotamobius torrentium Schr.) are critically endangered European species, their water quality requirements are not sufficiently known. This study aimed to investigate the physico‐chemical tolerance range of the noble and stone crayfish in the Czech Republic compared with those of the invasive spiny‐cheek crayfish (Orconectes limosus Raf.). At 1008 sites with crayfish either absent or present, the following 18 physico‐chemical variables were investigated: dissolved oxygen, pH, BOD5, CODCr, ammonia, ammonium ions, nitrite, nitrate ions, zinc, copper, iron, aluminium, calcium, sulphates, chlorides, total phosphorus, suspended solids, and conductivity. For the noble and stone crayfish, only minor differences in water quality were found. This indicates that the water quality requirements of these indigenous crayfish are likely to be very similar. However, significant differences in water quality were observed between locations inhabited by indigenous crayfish and those inhabited by the invasive spiny‐cheek crayfish. Based on these findings, we hypothesize that the invasive species is able to survive in locations with lower water quality. Simple logistic regression models were then used to examine relationships between the presence or absence of noble crayfish and each evaluated water quality variable. The presence of this species was related significantly with those variables that indicate nutrient enrichment (particularly ammonium, BOD5, and nitrite) and to iron. Overall, although the indigenous crayfish species were found at several sampling sites that had impaired water quality, the statistical analyses indicate that the indigenous species require water of high quality. Improvement in water quality is therefore an important step in sustaining indigenous crayfish populations. Copyright © 2012 John Wiley & Sons, Ltd.

“…In practice, it is estimated on the basis of overlapping life history traits, ecological requirements, morphologies and demographic characteristics. Unfortunately, the few reports in the literature on the ecology of Italian and European populations of A. pallipes (Scalici et al 2008;Trouilhe et al 2007;Neveu 2007;Demers et al 2006), as well as about morphological variation among taxa (Bott 1950;Karaman 1963;Brodsky 1983;Starobogatov 1995), are not comparable for these populations. Specific ecological studies, standardized for both Italian and French populations, need to be undertaken in order to demonstrate the presence or absence of exchangeability.…”

The endangered white-clawed crayfish Austropotamobius pallipes (Decapoda, Astacidae) east and west of the Maritime Alps: a result of human translocation?

The genetic variability among Italian populations of the white-clawed crayfish (Austropotamobius pallipes) was examined to determine their phylogeography and to assess their conservation status as a management unit. A fragment of the mitochondrial DNA COI gene of 107 specimens from ten populations was sequenced, and the phylogenetic relationships were established. Two out of three haplotypes sampled in two French populations from the Rhône basin were shared with Italian populations. Despite a moderate level of genetic variability within the Italian populations of A. pallipes, no genetic structure was revealed. It has been suggested that there have been translocation events throughout the Alpine barrier between the North-Western Italian basins and the Rhône basin. Genetic exchangeability of the French and Italian populations was demonstrated in this study, and a shift of conservation efforts towards the native, congeneric Austropotamobius italicus is recommended.

“…showed significant decreases in feeding, growth, and moulting rates when exposed to prolonged episodes of hypoxia (10 to 28 days; Stickle, 1993, 1994). Three European native species of freshwater crayfish, Austropotamobius pallipes, A. italicus and A. torrentium, demonstrated a disruption in the ion exchange process under hypoxia, but all tolerated very low oxygen concentrations for extended periods of time (Demers et al, 2006). Through physiological effects, hypoxia strongly enhances the rate of cadmium accumulation in gills and hepatopancreas of decapod shrimps; in particular, when heavy metal concentrations are low (Pierron et al, 2007).…”

Impacts of hypoxia on the structure and processes in pelagic communities (zooplankton, macro-invertebrates and fish)

Abstract. Dissolved oxygen (DO) concentration in the water column is an environmental parameter that is crucial for the successful development of many pelagic organisms. Hypoxia tolerance and threshold values are species-and stagespecific and can vary enormously. While some fish species may suffer from oxygen values of less than 3 mL O 2 L −1 through impacted growth, development and behaviour, other organisms such as euphausiids may survive DO levels as low as 0.1 mL O 2 L −1 . A change in the average or the range of DO may have significant impacts on the survival of certain species and hence on the species composition in the ecosystem with consequent changes in trophic pathways and productivity.Evidence for the deleterious effects of oxygen depletion on pelagic species is scarce, particularly in terms of the effect of low oxygen on development, recruitment and patterns of migration and distribution. While planktonic organisms have to cope with variable DOs and exploit adaptive mechanisms, nektonic species may avoid areas of unfavourable DO and develop adapted migration strategies. Planktonic organisms may only be able to escape vertically, above or beneath the Oxygen Minimum Zone (OMZ). In shallow areas only the surface layer can serve as a refuge, but in deep waters many organisms have developed vertical migration strategies to use, pass through and cope with the OMZ.Correspondence to: W. Ekau (wekau@zmt-bremen.de) This paper elucidates the role of DO for different taxa in the pelagic realm and the consequences of low oxygen for foodweb structure and system productivity. We describe processes in two contrasting systems, the semi-enclosed Baltic Sea and the coastal upwelling system of the Benguela Current to demonstrate the consequences of increasing hypoxia on ecosystem functioning and services.
