通过在G. laevis和G.维多利亚靠近其南部(沿海)限制。繁殖-呼唤结构和2个肌肉蛋白系统被用来分析这些形态相似的物种之间的相互作用。该区域基于繁殖召唤结构,很窄(9-30公里),大部分替换发生在2公里以上。接触样品由假定的亲本个体和重组产物组成,因此该区域的这一部分可以被描述为与杂交的重叠。这与早先分析的样带附近的北方(内陆)的限制区,那里有一个狭窄的整合与杂种优势的替代人口。在南部样带,2肌肉蛋白质系统有更广泛的替代区比繁殖电话(最小宽度为33和72公里)。肌肉蛋白质区域彼此处于不同的地理位置,并且与基于育种呼叫的区域几乎没有重叠。这些种的3个性状的更替模式似乎是相互独立的,并强调了杂种区的复杂性。
A transect was established across the hybrid zone between G. laevis and G. victoriana near its southern (coastal) limit. The breeding-call structure and 2 muscle protein systems were used to analyze the interaction between these parapatric, morphologically-similar species. The zone, based on breeding-call structure, is narrow (9-30 km), with most of the replacement occurring over 2 km. Contact samples consist of putative parental individuals and recombination products, so that this section of the zone may be described as an overlap with hybridization. This contrasts with an earlier analysis of a transect near the northern (inland) limit of the zone, where there is a narrow integradation with hybrids predominating in the replacement populations. In the southern transect, the 2 muscle protein systems have much broader zones of replacement than that for breeding calls (minimum widths of 33 and 72 km). The muscle protein zones are in different geographic positions from each other, and there is little overlap with the zone based on breeding calls. The patterns of replacement of the 3 characters in these species appear to be independent of one another, and emphasize the complex nature of hybrid zones.
