1Pollinator attraction in Cornus capitata (Cornaceae): the relative role of visual and olfactory cues显示文摘Aims it is generally accepted that visual displays and floral scent play important roles in communication between flowering plants and their pollinators.However,the relative role of visual and olfactory cues in pollinator attraction is largely unknown.in this study,we determined the roles of both types of cue in attracting pollinators to Cornus capitata,a medium sized tree with each capitulum sur-rounded by four large,white,petaloid bracts.Methods Pollinator observations and pollination experiments were con-ducted in a natural population;the inflorescences’visual and olfactory signals were characterized by spectral and chemical analyses;the responses of pollinators to visual and olfactory cues were tested using dual-choice behavioural bioassays;the relative roles of visual and olfactory cues in pollinator attrac-tion were tested by comparing the responses of pollinators to inflorescences subjected to three experimental treatments(intact,all bracts removed,and capitulum removed)within the natural population.Important Findings For fruit set,C.capitata is entirely dependent on pollinators,with a bee,Anthophora sp.,being the main pollinator.bracts present high colour distance and green contrast against the leaves.Twelve volatile compounds in the floral scent were detected,most of which have previously been reported to be attractive to a broad spectrum of bee species.behavioural bioassays showed that both,visual cues alone and olfactory cues alone,are attractive to pollinating bees.However,vis-ual cues alone attracted significantly more approaches than olfactory cues alone,while olfactory cues alone elicited a significantly higher landing percentage than visual cues alone.The finding suggests that,in the C.capitata-Anthophora sp.interaction,visual cues are mainly used for location from long distances,while olfactory cues mainly aid landing from short distances.our results indicate that different modalities of floral cues should be considered together to understand fully the communication between flowering plant and pollinators.Bo Song Yang Niu Jürg Stöcklin Gao Chen De-Li Peng Yong-Qian Gao Hang Sun 2015Journal of Plant Ecology2015,8,2:3
2Onboard GRB trigger algorithms of SVOM-GRM显示文摘The Gamma-Ray Monitor(GRM)is a high energy detector onboard the future Chinese-French satellite named the Space-based multi-band astronomical Variable Object Monitor which is dedicated to studies of gamma-ray bursts(GRBs).This paper presents an investigation of the algorithms that look for GRBs by searching for a significant increase in the photon count rate for the computer onboard GRM.The trigger threshold and trigger efficiency,which are based on a given sample of GRBs,are calculated with the algorithms.The trigger characteristics of onboard instruments GRM and ECLAIRs are also analyzed.In addition,the impact of solar flares on GRM is estimated,and a method to distinguish solar flares from GRBs is investigated.Dong-Hua Zhao Bo-Bing Wu Li-Ming Song Yong-Wei Dong Stphane Schanne Bertrand Cordier Jiang-Tao Liu 2013Research in Astronomy and Astrophysics2013,13,11:2
