Contrasting allozyme and RAPD variation in spider populations from patchy forest habitats 总被引:5,自引:1,他引:4
During the last 1000 years, massive deforestation events have occurred in Flanders (the northern part of Belgium) and the remaining forests have become very isolated patches. It is expected that organisms bound to these patchy forest habitats and with limited dispersal capacities will likely experience strong effects of genetic drift. One such organism is the spider Coelotes terrestris. Allozyme data suggested that 10 Flemish populations of this spider showed little genetic variation, as only one out of 20 loci was polymorphic (phosphoglucose isomerase). In view of this result, we used random amplified polymorphic DNA (RAPD) markers to test whether this lack of allozyme diversity is an inherent feature of the populations and/or species studied or whether it rather reflects a characteristic of the markers and/or methods used. Since the RAPD data revealed a substantial amount of genetic diversity in the same 10 populations, our results suggest that the latter is true. Furthermore, the RAPD data agree with the expectations for an organism with low dispersal capacities that has lived in isolated forest patches for at least 200 generations. Supplemented with the results of other techniques and studies, these findings might be of importance for the future conservation of this spider species in Flanders. 相似文献

记叙我国隙蛛属一新种:微光隙蛛Coelotes nitidus sp. nov..微光隙蛛,新种Coelotes nitidus sp.nov. (图1~4)新种与双刃隙蛛Coelotes bicultratus Chen, Zhao and Wang, 1991 近似, 但外雌器外部和内部形态都有明显区别.新种模式标本采集地是位于湖北省恩施地区利川市城区南10 km处的腾龙洞.距洞口约2*!km处生存数百只蝙蝠,当地人称为蝙蝠厅.模式标本采自蝙蝠厅底部两侧的石缝中.因此处仅有微光,故命名为微光隙蛛. 相似文献
