“…The presence of reproductive isolation in sympatry also supports the notion that the two taxa are distinct species (Higuchi and Goto, 1996;Kitano et al, 2007Kitano et al, , 2009 (Kume et al, 2005), sexual isolation (Kitano et al, 2009), ecological selection against migrants (Kume et al, 2010), hybrid male sterility (Kitano et al, 2007(Kitano et al, , 2009) and ecological selection against hybrids (Kitano et al, 2009).…”

Stickleback fishes have been established as a leading model system for studying the genetic mechanisms that underlie naturally occurring phenotypic diversification. Because of the tremendous diversification achieved by stickleback species in various environments, different geographical populations have unique phenotypes and genotypes, which provide us with unique opportunities for evolutionary genetic research. Among sticklebacks, Japanese species have several unique characteristics that have not been found in other populations. The sympatric marine threespine stickleback species Gasterosteus aculeatus and G. nipponicus (Japan Sea stickleback) are a good system for speciation research. Gasterosteus nipponicus also has several unique characteristics, such as neo-sex chromosomes and courtship behaviors, that differ from those of G. aculeatus. Several freshwater populations derived from G. aculeatus (Hariyo threespine stickleback) inhabit spring-fed ponds and streams in central Honshu and exhibit year-round reproduction, which has never been observed in other stickleback populations. Four species of ninespine stickleback, including Pungitius tymensis and the freshwater, brackish water and Omono types of the P. pungitius-P. sinensis complex, are also excellent model systems for speciation research. Anthropogenic alteration of environments, however, has exposed several Japanese stickleback populations to the risk of extinction and has actually led to extinction of several populations and species. Pungitius kaibarae, which is endemic to East Asia, used to inhabit Kyoto and Hyogo prefectures, but is now extinct. Causes of extinction include depletion of spring water, landfill of habitats, and construction of rivermouth weirs. Here, we review the importance of Japanese sticklebacks as genetic resources, the status of several endangered stickleback populations and species, and the factors putting these populations at risk.

“…It is hypothesized that movement plays a more important role in dense habitats than in open habitats, because motion can effectively draw the receiver's attention in the presence of moving backgrounds of dense vegetation (McKenzie & Keenleyside, 1970;Fleishman, 1992;Peters & Evans, 2003). In a region where the two forms are breeding in sympatry, the JA males tend to breed in the more open habitat, while the PA males tend to breed in a more complex vegetated habitat (Kume et al, 2005). Additional studies on the breeding habitats of multiple sympatric populations of these two forms will be required to understand the relationship between breeding ecology and courtship divergence in the Japanese sympatric pair.…”

“…Anadromous threespine sticklebacks of the sympatric Pacific Ocean (PA) and Japan Sea (JA) forms were collected from Akkeshi Bay (Kume et al, 2005), Japan, in May 2003May , 2005May and 2006. First, the PA and JA forms were distinguished by external morphology: PA fish are larger than JA fish in standard length, and the caudal lateral plates are larger and more robust in PA fish than in JA fish (Ikeda, 1933;Higuchi & Goto, 1996).…”

SummaryCourtship displays are an important component of animal reproduction, and divergence in these displays can play an integral role in promoting or maintaining reproductive isolation between species. The courtship behaviour of the threespine stickleback (Gasterosteus aculeatus) has been extensively characterized. In Japan, there are two lineages of threespine stickleback that are genetically differentiated and reproductively isolated when found in regions of sympatry. We have previously shown that males of the Pacific Ocean lineage perform the zig-zag dance, while sympatric males of the Japan Sea lineage perform a different dance, which we have termed the rolling dance (Kitano et al., 2007, Biol. J. Linn. Soc. 91: 671-685). As a first step towards understanding the role of the courtship display in female mate choice and sexual isolation between this sympatric pair, we conducted a more detailed analysis of divergence between the courtship displays of the Pacific Ocean and Japan Sea males. Kinematic analysis revealed that the tempo of the zig-zag dance is two times faster than the tempo of the rolling dance. A detailed analysis of head movements during the courtship dance revealed that the Japan Sea males erect their gill covers, extend their red throats, and open their mouths more frequently during the rolling dance than the Pacific Ocean males do during the zig-zag dance. These results demonstrate that there is extensive divergence between sympatric Pacific Ocean and Japan Sea males in both the motor patterns and the tempo of their courtship displays. Thus, the Japanese sympatric stickleback pair provides a good system to study the role of courtship behaviour in speciation, as well as the genetic mechanisms that underlie the divergence of kinematics and motor patterns in courtship behaviour.

“…The matured adult and juvenile fishes were collected at four tidal pools using a dip net (2 mm in mesh size) from May to July in 2003 (Figure 1), and measured for standard length (SL) and total length (TL) to the nearest 0.05 mm using a caliper. In addition, categories of maturation in both sexes were recorded, following to Kume et al (2005).…”

SynopsisThe Japan sea form of the threespine stickleback, Gasterosteus aculeatus, was found to spawn in the seawater tidal pool of the Cape Benkei, western Hokkaido Island, Japan, in 2001 and 2003. Nest-guarding males, adult females and juveniles of this form were also observed in four tidal pools of the Capes Benkei, Kabuto and Kamui, in 2001-2003. Otolith Sr:Ca ratios in sticklebacks collected from these tidal pools were relative high from the core to the edge, suggesting they lived in seawater environments throughout its life cycle. These findings suggest that a part of the Japan Sea form's individuals in western Hokkaido Island have the potential to breed in the coastal sea and the life history style has evolved in dependence on the seawater environment.2
