1Complementary fruiting phenologies facilitate sharing of one pollinator fig wasp by two fig trees显示文摘Aims most pollinator fig wasps are host plant specific,with each spe-cies only breeding in the figs of one fig tree species,but increasing numbers of species are known to be pollinated by more than one fig wasp,and in rare instances host switching can result in Ficus species sharing pollinators.in this study,we examined factors facilitating observed host switching at Xishuangbanna in southwestern(sW)China,where Ficus squamosa is at the northern edge of its range and lacks the fig wasps that pollinate it elsewhere,and its figs are colonized by a Ceratosolen pollinator that routinely breeds in figs of F.heterostyla.Methods We recorded the habitat preferences of F.squamosa and F.heterost-yla at Xishuangbanna,and compared characteristics such as fig size,location and colour at receptive phase.Furthermore,the vegetative and reproductive phenologies in the populations of F.squamosa and F.heterostyla were recorded weekly at Xishuangbanna Tropical botanical garden for 1 year.Important Findings Ficus squamosa is a shrub found near fast-flowing rivers,F.heterostyla is a small tree of disturbed forest edges.although preferring different habitats,they can be found growing close together.both species have figs located at or near ground level,but they differ in size when pollinated.Fig production in F.squamosa was concentrated in the colder months.F.heterostyla produced more figs in summer but had some through-out the year.The absence of its normal pollinators,in combination with similarly located figs and partially complementary fruiting patterns appear to have facilitated colonization of F.squamosa by the routine pollinator of F.heterostyla.The figs probably also share similar attractant volatiles.This host switching suggests one mechanism whereby fig trees can acquire new pollinators and emphasizes the likely significance of edges of ranges in the genesis of novel fig tree-fig wasp relationships.Gui-Xiang Liu Da-Rong Yang Yan-Qiong Peng Stephen G.Compton 2015Journal of Plant Ecology2015,8,2:6
2基于18S基因序列的姬小蜂分子系统发育(英文)显示文摘本文基于18S rDNA部分序列,用MP和Baysian方法研究了姬小蜂科的系统发育,对姬小蜂科的单系性及其与其它小蜂科间的关系进行了讨论。姬小蜂亚科、灿姬小蜂亚科和啮姬小蜂亚科形成三个独立的支系,研究结果支持它们各自的单系性,但本结果没有明确姬小蜂科的单系性。研究结果同时还支持瑟姬小蜂族、扁股姬小蜂族和狭面姬小蜂族三个族的地位,但不支持姬小蜂族的地位。姬小蜂科的单系性及其与其它小蜂间的关系还需更多的形态学数据和更多的基因序列来进一步研究[动物学报52 (2) : 288 -301 , 2006]。沙忠利 朱朝东 Robert W.MURPHY 黄大卫 Stephen G.COMPTON 2006动物学报2006,52,2:5
