“…To investigate this further in the four experimental populations, we sequenced 729 bp of the mitochondrial control region (Takahashi & Goto 2001;Mattern 2004) for five individuals from Brannen, Dougan and North Lake, and four from Sproat Lake. We also sequenced fish from two marine populations: six from the Nanaimo River (on the Strait of Georgia) and seven from Grappler Inlet (near Bamfield on the west coast of Vancouver Island).…”

Strong assortative mating between allopatric sticklebacks as a by-product of adaptation to different environments

Speciation involves the evolution of reproductive isolation between populations. One potentially important mechanism is the evolution of pre-or postzygotic isolation between populations as a by-product of adaptation to different environments. In this paper, we tested for assortative mating between allopatric stickleback populations adapted to different ecological niches. Our experimental design controlled for interpopulation interactions and non-adaptive explanations for assortative mating. We found that prezygotic isolation was surprisingly strong: when given a choice, the majority of matings occurred between individuals from similar environments. Our results indicate that the by-product mechanism is a potent source of reproductive isolation, and likely contributed to the origin of sympatric species of sticklebacks.

“…From a comparative morphological perspective, this information is not only relevant to the evolution of armor within the threespine stickleback radiation (e.g., partially armored freshwater, fully armored anadromous), but also could form the basis for comparison with other stickleback species that have lateral plates (e.g., Brook stickleback, Culaea inconstans, ninespine stickleback, Pungitius pungitius) (Mattern, 2004). Micro-computed tomography (lCT) was employed to create full three-dimensional images of the dorsal spines and basal plate, lateral plates, pelvic girdle and spines and to assess structural and material properties such as the spatial distribution of thickness, the cross-sectional geometry, plateto-plate interconnections and overlap, bone mineral density, and images of disassembled armor components with dorsal spines (top), lateral plates (center), and pelvic girdle/spines (bottom) in rest position.…”

“…The ninespine stickleback Pungitius pungitius is a small euryhaline fish belonging to the family Gasterosteidae (Pisces) known as sticklebacks, an important model system in evolutionary biology (Mattern, 2004). This species has a nearly continuous circumpolar distribution, occurring in fresh and coastal waters of northern Eurasia and North America (Münzing, 1969;Wootton, 1976).…”

Hybrid Male Sterility between the Fresh- and Brackish-water Types of Ninespine Stickleback Pungitius pungitius (Pisces, Gasterosteidae)

-Two ecologically distinct forms, fresh-and brackish-water types, of ninespine stickleback coexist in several freshwater systems on the coast of eastern Hokkaido. Recent genetic analyses of 13 allozyme loci revealed genetic separation between the two types even though their spawning grounds were in close proximity. On the other hand, there is only a small difference in mitochondrial DNA (mtDNA) sequence between the two types suggesting that they diverged quite recently or that mtDNA introgression occurred between them. To test for postzygotic reproductive isolating mechanisms and hybrid mediated gene flow, we examined the viability and reproductive performance of reciprocal F 1 hybrids. The hybrids grew to the adult size normally and both sexes expressed secondary sexual characters in the reciprocal crosses. The female hybrids were reciprocally fertile, while the male hybrids were reciprocally sterile. Histological and flow-cytometric analyses of the hybrid testis revealed that the sterility pattern was classified as 'gametic sterility,' with gonads of normal size but abnormal spermatogenesis. To our knowledge, the present finding is a novel example of one sex hybrid sterility in the stickleback family (Gasterosteidae).
