Similarly, phylogeography of mitochondrial and microsatellite markers in Siberian sturgeon Acipencer baerii presently distributed in all major Siberian rivers strongly indicates that Baikal was a single refugium for this species during (Barmintseva and Mugue, in press).…”

Endemic species flocks inhabiting ancient lakes, oceanic islands and other long-lived isolated habitats are often interpreted as adaptive radiations. Yet molecular evidence for directional selection during species flocks radiation is scarce. Using partial transcriptomes of 64 species of Lake Baikal (Siberia, Russia) endemic amphipods and two nonendemic outgroups, we report a revised phylogeny of this species flock and analyse evidence for positive selection within the endemic lineages. We confirm two independent invasions of amphipods into Baikal and demonstrate that several morphological features of Baikal amphipods, such as body armour and reduction in appendages and sensory organs, evolved in several lineages in parallel. Radiation of Baikal amphipods has been characterized by short phylogenetic branches and frequent episodes of positive selection which tended to be more frequent in the early phase of the second invasion of amphipods into Baikal when the most intensive diversification occurred. Notably, signatures of positive selection are frequent in genes encoding mitochondrial membrane proteins with electron transfer chain and ATP synthesis functionality. In particular, subunits of both the membrane and substrate-level ATP synthases show evidence of positive selection in the plankton species Macrohectopus branickii, possibly indicating adaptation to active plankton lifestyle and to survival under conditions of low temperature and high hydrostatic pressures known to affect membranes functioning. Other functional categories represented among genes likely to be under positive selection include Ca-binding muscle-related proteins, possibly indicating adaptation to Ca-deficient low mineralization Baikal waters.

“…Much more surprisingly, we find genetic differentiation between lake‐ and stream‐dwelling populations within the Aare catchment. Although sculpins are known to occur in either environment (Kontula & Vainola, ; Kottelat & Freyhof, ; Goto et al ., ), such a lake‐stream differentiation within a drainage was unknown for Cottus gobio (Hänfling & Brandl, ,b; Vonlanthen et al ., ; Neuenschwander et al ., ; Seehausen & Wagner, ; Goto et al ., ). Habitat‐dependent ecotype formation along a lake‐stream axis is well known in some other freshwater fishes where it occurs with some regularity (Seehausen & Wagner, ).…”

“…It is the most widely distributed of the 16 known and described, predominantly allopatric European freshwater Cottus species. It is thought to predominantly occur in streams from Scandinavia to Northern Italy, characterized by fast flowing, well-oxygenated water and structured benthic habitats where it feeds mainly on benthic invertebrates (Kottelat & Freyhof, 2007;Goto et al, 2015). In other parts of the northern hemisphere, other sculpin species are also reported from littoral zones of large cold lakes with some rare accounts of profundal lacustrine occurrences (Goto et al, 2015).…”

Ecological speciation and adaptive radiation are key processes shaping northern temperate freshwater fish diversity. Both often involve parapatric differentiation between stream and lake populations and less often, sympatric intralacustrine diversification into habitat- and resource-associated ecotypes. However, few taxa have been studied, calling for studies of others to investigate the generality of these processes. Here, we test for diversification within catchments in freshwater sculpins in a network of peri-Alpine lakes and streams. Using 8047 and 13 182 restriction site-associated (RADseq) SNPs, respectively, we identify three deeply divergent phylogeographic lineages associated with different major European drainages. Within the Aare catchment, we observe populations from geographically distant lakes to be genetically more similar to each other than to populations from nearby streams. This pattern is consistent with two distinct colonization waves, rather than by parapatric ecological speciation after a single colonization wave. We further find two distinct depth distribution modes in three lakes of the Aare catchment, one in very shallow and one in very deep water, and significant genomewide differentiation between these in one lake. Sculpins in the Aare catchment appear to represent an early-stage adaptive radiation involving the evolution of a lacustrine lineage distinct from parapatric stream sculpins and the repeated onset of depth-related intralacustrine differentiation.

“…Kinziger et al (2005) treated the Sakhalin sculpin C. amblystomopsis (along with C. nozawae, endemic to the Japan Islands) as a Cephalocottus clade or subgenus within the family Cottidae. Goto et al (2015) considered C. amblystomopsis within the genus Cottus as the lineage C from East Asia. The evolutionary history and phylogenetic relationships of C. amblystomopsis remained unclear due to limited genetic data available for the species.…”
