Abstract A major challenge of contemporary marine science is disentangling consequences of climate change from other impacts, and studying non-target species and using historical resources to see long-term trends can meet this need. However, such data can be fragmented, and here, we demonstrate the potential of leveraging across sources for insight. We assembled a variety of historical sources such as scientific and personal observations, anecdotal information, and archival fisheries data to create an abundance time series on threespine stickleback Gasterosteus aculeatus in the White Sea starting in the late 19th century—the longest time series for this species. Stickleback peaked during the warm period of the 1920–1940s and declined during the colder period of the 1950–1990s and now is the most numerous vertebrate in the sea. Analyses of historical and recent time series based on our own data (2007–2019) showed that stickleback abundance decreases during colder winters. It is not associated with zooplankton biomass, positively correlated with herring Clupea sp. catches and negatively with navaga Eleginus navaga catches. Large population size and food web interactions suggest that change in stickleback abundance has the potential to affect the entire White Sea ecosystem.

AbstractReproductive isolation was investigated among sympatric lateral plate morphs of threespine stickleback from the White Sea basin and also among phenotypically similar morphs from the distant Kamchatka River basin (Lake Azabachije). Female choice tests show that gene flow is restricted among the completely plated and low plated morphs at both locations; behavioural isolation between these morphs is complete among Lake Azabachije fish, and nearly so (93% positive assortative mating) among White Sea basin fish. However, the experiments also demonstrate that there are no barriers to reproduction among the Azabachije and White Sea complete morphs, among the Azabachije low and White Sea complete morphs, nor among the Azabachije complete and White Sea low morphs. In addition, there is no evidence of barriers to gene flow among the low and partially plated morphs. Therefore, although gene flow is restricted among the extreme morphs within each locality, nevertheless gene exchange is possible, either directly or secondarily, among all phenotypes. The reproductive isolation between the complete and low morphs from the White Sea basin developed in situ no more than eight generations after the sticklebacks were introduced into an isolated freshwater pond. Therefore behavioural isolation can evolve very rapidly among the lateral plate phenotypes of Gasterosteus aculeatus.

Sexual dimorphism (SD) in the threespine stickleback Gasterosteus aculeatus reflects the different roles of the sexes in reproduction and their adaptations to different ecological niches. We quantified SD in one population of marine stickleback from the White Sea, collected during the spawning period from three spawning grounds, each at a distance of 5 km or less from the others. We used a landmark-based approach to quantify variation in 44 morphometric linear traits. In total, 749 females and 693 males were analyzed. In males, anterior body parts are larger — the base of the caudal fin and armor structures such as the first and second dorsal spines and the pelvic spine. Females have larger posterior bodies — the abdomen, pelvic girdle and the third dorsal spine. The SD of caudal body parts exhibits complex patterns. In White Sea threespine stickleback, SD patterns are generally similar to other populations of the species, but more often show male-biased patterns. Female-biased size SD may be associated with the female biased sex ratio of White Sea stickleback.

Abstract Adaptation of threespine stickleback to freshwater involves parallel recruitment of freshwater alleles in clusters of closely linked sites, or divergence islands (DIs). However, it remains unclear to what extent the DIs and the alleles that constitute them coincide between populations that underwent adaptation to freshwater independently. We examine threespine sticklebacks from ten freshwater lakes that emerged 500–1500 years ago in the White Sea basin, with the emphasis on repeatability of genomic patterns of adaptation among the lake populations and the role of local recombination rate in the distribution and structure of DIs. The 65 detected DIs are clustered in the genome, forming 12 aggregations, and this clustering cannot be explained by the variation of the recombination rate. Only 21 of the DIs are present in all the freshwater populations, likely being indispensable for successful colonization of freshwater environment by the ancestral marine population. Within most DIs, the same set of single nucleotide polymorphisms (SNPs) distinguish marine and freshwater haplotypes in all the lake populations; however, in some DIs, freshwater alleles differ between populations, suggesting that they could have been established by recruitment of different haplotypes in different populations.
