“…In fact, temperature could influence the rates of genetic divergence among populations and rates of speciation in communities (Brucet et al, 2013). In our study, temperature annual range (TAR) and annual mean temperature (AMT) were as important in the determination of fish assemblages, which is consistent with Crisp (1996) and Mann (1996) who considered these two factors as of high importance for the biological requirements of freshwater fish. The threshold value of TAR and AMT identified in the tree analysis were 50 • C and 17.2 • C respectively.…”

“…Temperature is an important factor that influences fish distribution through fish metabolism (Gillooly et al, 2001), breeding (Mills and Mann, 1985), development and growth (Mann, 1996;Wolter, 2007) and behavior (Taniguchi et al, 1998). In fact, temperature could influence the rates of genetic divergence among populations and rates of speciation in communities (Brucet et al, 2013).…”

“…For instance in Northern lakes, the air temperature could cover a large range annually from warm season to cold season (Wang and Dou, 1998). Some European freshwater fishes (Buisson et al, 2010;Pont et al, 2005;Mann, 1996) and American species (Rathert et al, 1999) were also demonstrated to be great impacted by the TAR. Although each fish species has a thermal preference characterized by a tolerance range of temperatures, they are flexible and can adapt to a certain extent with physiological adjustments (Johnson and Kelsch, 1998) or behavioral thermoregulation (Heggenes et al, 1993).…”

a b s t r a c tThe present study was designed to investigate the relative importance of climatic (temperature and precipitation), geographic (altitude) and morphometric (lake area) factors in predicting fish species richness and assemblages in Chinese lakes at a large spatial scale. Two recursive partitioning tree-based approaches: Classification and Regression Trees (CARTs) and Multivariate Regression Trees (MRTs) were employed to generate predictive models respectively. Six fish assemblages were thus defined from the MRT model. The results indicated that lake altitude was the main determinant for predicting fish assemblages in Chinese lakes (30.43%), followed by precipitation of the driest month (10.47%), temperature annual range (3.62%) and annual mean temperature (3.15%). Validated CART model implied that precipitation of driest month, maximum temperature of warmest month and lake area were the main predictors in determining fish species richness patterns. Overall, our results indicated that the altitudinal extent and range of climatic variation was sufficient to overshadow the area effect in predicting fish species richness and assemblages in Chinese lakes. At the macroecological scale, the effect of temperature and precipitation on fish richness and assemblages also suggests future changes in fish diversity as a consequence of climate change.

“…After hatching, larvae descend in prevailing currents of rivers along vegetated margins. Late larvae and early juveniles occur in shallow shoreline habitats, and when they grow leave the shores for faster-flowing areas (Mann 1974;Mills 1981;Mann 1996). Common dace are omnivorous, with a highly varied diet.…”

Early development and allometric growth patterns of rheophilic cyprinid common dace Leuciscus leuciscus (Cyprinidae: Leuciscinae)

The present work is the first comprehensive description of easily recognizable morphological changes, allometric growth, and behaviour during early ontogeny of endangered common dace Leuciscus leuciscus, establishing a reference for its normal development under laboratory conditions. Based on the external morphology, three different periods and eight characteristic steps (ES9-JS1; ES-embryonic steps, JS-juvenile steps) were identified between hatching and 30 days post-hatch at 25°C. This study shows that all allometric changes occurred after notochord flexion across a wide range of body lengths (15.35-21.78 mm TL) reflecting the larvae-juvenile transition. Observations on the early development of common dace confirmed the relatively uniform development of cyprinid species and support the hypothesis of differential growth patterns for primary functions during early ontogeny. Differences in relative growth between common dace and other species might be attributed to their different size at hatching, behaviour, and environmental cues.

“…Although these species have clear preferences for warmer temperature than brown trout, minnow and stone loach, it is thus still unclear why a marked shift in BPUE at 20°C was observed. Finally, a specific threshold at 22°C was defined from the variations in the biomass of black bullhead, which can reproduce only in water warmer than 20°C (Mann, 1996;Keith and Allardi, 2001;Wolter, 2007) and has very high tolerance for temperature above 30°C (Bruslé and Quignard, 2001; FishBase, 2016). Our results are globally consistent with the current knowledge regarding the temperature preferences of European species.…”

-The management of lakes requires the definition of physico-chemical thresholds to be used for ecosystem preservation or restoration. According to the European Water Framework Directive, the limits between physico-chemical quality classes must be set consistently with biological quality elements. One way to do this consists in analyzing the response of aquatic communities to environmental gradients across monitoring sites and in identifying ecological community thresholds, i.e. zones in the gradients where the species turnover is the highest. In this study, fish data from 196 lakes in France were considered to derive ecological thresholds using the multivariate method of gradient forest. The analysis was performed on 25 species and 36 environmental parameters. The results revealed the highest importance of maximal water temperature in the distribution of fish species. Other important parameters included geographical factors, dissolved organic carbon concentration and water transparency, while nutrients appeared to have low influence. In spite of the diversity of species responses to the gradients, community thresholds were detected in the gradients of the most important physico-chemical parameters and of total phosphorus and nitrate concentrations as well. The thresholds identified in such macroecological study may highlight new patterns of species natural distribution and improve niche characterization. Moreover, when factors that may be influenced by human activities are involved, the thresholds could be used to set environmental standards for lake preservation.Keywords: ecological threshold / gradient forest / fish / lake / water quality Résumé -Seuils physico-chimiques dans la distribution des poissons des plans d'eau français.La gestion des plans d'eau nécessite la définition de seuils physico-chimiques pour la préservation ou la restauration des écosystèmes.

L'analyse a porté sur 25 espèces avec 36 paramètres environnementaux. Les résultats ont révélé que la température maximale était le facteur le plus important dans la distribution des espèces de poissons. Les autres paramètres importants étaient les facteurs géographiques, la concentration en carbone organique dissous et la transparence de l'eau alors que les nutriments semblaient avoir peu d'influence.
