“…However, it remains largely unknown about biological processes and signaling pathways that are required for the development of difference in cold tolerance and cold acclimation of sh. Songpu mirror carp and Barbless carp are two closely related species of the carp family since they can hybrid to generate the offspring [39]. Previous studies have shown that Songpu mirror carp can easily survive in a frozen-over pond and some free water below the ice, but Barbless carp cannot survive in ponds of Heilongjiang province during winter [36].…”

“…Previous studies have reported that Songpu mirror carp (Cyprinus carpio.) have a strong ability of cold tolerance [37,38] and Barbless carp (Cyprinus pellegrini) that speci cally live in Xingyun Lake of the Yunnan-Guizhou Plateau in China [39] are sensitive to cold temperature [36]. In this study, two of closely related members of the carp family, Songpu mirror carp and Barbless carp that can hybrid to generate the offspring [39], were used to identify differentially expressed factors and activated signaling pathways that may play crucial roles in the development of differences in cold tolerance and acclimation of carps.…”

Background Closely related species of the carp family ( Cyprinidae ) have evolved distinctive abilities to survive under cold stress, but molecular mechanisms underlying the generation of cold resistance remain largely unknow. In this study, we compared transcriptomic profiles of two carp species to identify key factors and pathways for cold tolerance and acclimation. Results Larvae of Songpu mirror carp and Barbless carp that were pretreated at 18°C for 24 hours significantly improved their survival rates under lethal cold temperature at 8°C or 10°C, indicating that two carp species possess the ability of cold acclimation. However, Songpu mirror carp exhibited stronger abilities of cold tolerance and acclimation than Barbless carp. Transcriptomic profiles of Songpu mirror carp and Barbless carp larvae at 28°C and 18°C were compared during cold acclimation through RNA-seq. Differentially expressed genes that are closely associated with the differences in cold acclimation between two carp species were identified through bioinformatics and Venn's diagram analysis. GO enrichment analysis of these genes indicated that cellular component assembly involved in morphogenesis, secondary alcohol metabolism and drug transport were the most up-regulated biological processes during cold acclimation of Songpu mirror carp. Conversely, positive regulation of macroautophagy, intracellular protein transport, and organonitrogen compound catabolism were the most down-regulated biological processes during cold acclimation of Barbless carp. KEGG enrichment analysis revealed that factors in the FoxO-related signaling pathways are mainly responsible for the development of differences in cold tolerance and acclimation between two carp species since altering the phosphorylation of key proteins in the FoxO-related signaling pathways with inhibitors or an activator significantly decreased the cold tolerance and acclimation of Songpu mirror carp. These data provided key clues for dissection of molecular mechanisms underlying the development of cold tolerance and acclimation in carps. Conclusions These findings indicate that larvae of two carp species possess different abilities of cold tolerance and can build cold acclimation under mild low temperature. Multiple biological processes and FoxO-related signaling pathways are closely associated with the development of differences in cold tolerance and acclimation between two carp species.

“…However, the extinction process actually needs a relatively long time to complete its course (Scott & Helfman, 2001;Michael, 2002;Rahel, 2002). Even if most introduced fishes are known as harmful to native species, due to increased competition for food (Qin & Xie, 2007), native fish egg predation (Du & Li, 2001) and hybridization (Tang & Chen, 2012), the percentages of introduced versus extirpated fish species within lakes were not correlated during the intermediate period (10-20 years after the first introduction wave).

Aim Introductions of exotic species have globally modified the structure and function of native assemblages and are recognized as one of the major threats to biodiversity. The current patterns, processes and consequences of invasion have been intensively studied globally, but studies reporting the long-term dynamics of invasions over large areas are rare. Here, we measured how the temporal changes in fish assemblage composition in a Chinese highland isolated-lake landscape drive taxonomic dissimilarity and its turnover component over three successive time periods spanning the last 75 years.Location Yun-Gui Plateau, 15 isolated lakes.Methods The Sørensen and Simpson indices were used to quantify changes in taxonomic dissimilarity and its turnover component over 1940-2015. Results We report a decline of taxonomic dissimilarity between lakes through time, mainly due to a decrease in species turnover. Such a homogenization process was due to the combined effects of the invasion of the same non-native species in most lakes and of extirpation of narrow endemic species. The strong decline in species dissimilarity and turnover was triggered by a high historical level of dissimilarity among assemblages. At a regional scale, the combined effect of introductions and extirpations modified the distance decay of taxonomic similarity between lakes. Surprisingly, this beta-diversity gradient is currently no longer supported by biogeographic and evolutionary processes, but by the human-mediated introduction of distinct exotic species in some lakes. Moreover, an extinction debt process was evident as extirpations sometimes occurred many years after the introduction of non-native species.Main conclusions Our study highlights that high historical differentiation of fishes in isolated lakes has turned to homogenization with dramatic loss of endemic species due to intensive introductions. This provides a striking example of human domination over an extended lake landscape and its associated irreparable biodiversity damages on isolated systems historically dominated by narrow endemic species.

“…However, severe negative impacts have also been caused by these translocated fishes. Many endemic species have been placed at a high risk of extinction as a result of hybridization (Tang and Chen 2012), competition for food (Qin et al 2007), competition for habitat , predation (Xiong et al 2008), and habitat and ecosystem alterations ) caused by these translocated fishes. The focus of the current study has not been on these freshwater fish species translocated within China, however many lessons have been provided by these species introductions.…”

Non-native fishes are regarded as a serious threat to freshwater biodiversity. However, little information exists about non-native freshwater fish in China. This study compiled an inventory of non-native freshwater fish species in China based on various sources. The inventory includes a total of 439 freshwater fish species belonging to 22 orders, 67 families, and 256 genera. The four most dominant orders were Perciformes, Characiformes, Siluriformes, and Cypriniformes, accounting for 38.50 14.81 13.90, and 11.16 % of the non-native freshwater fish in China, respectively. Over one-third of non-native freshwater fish species were of South American origin (35.54 %), followed by Asian (23.01 %), and African (21.41 %) origins. The aquarium and aquaculture industries are the two main vectors responsible for the introduction of non-native fish species into China. The status and potential impacts of most non-native fishes are uncertain. This study summarizes the known ecological and economic effects of non-native freshwater fishes in China. The results demonstrate that there are enormous positive and negative impacts of non-native fishes on the economy, and that some non-native species are potential threats to humans and biodiversity in China. Therefore, more attention should be focused on non-native fishes in China in the future.
