Designing ‘trait-based null model’ approaches to investigate community assembly mechanisms
2014
SPEEAECOLDURGEAPSIéquipe CAPA; During the last decade, many studies have addressed the signature of community assembly processes by assessing the deviation of a functional diversity pattern from that expected in null communities, using a randomization algorithm. The basic principle has been to compare the functional structure of a ‘local community’ with a set of randomly generated communities from a ‘regional species pool’. Specifically, it allows assessing the extent to which species constituting a community are functionally more or less similar than expected under the assumption of a random assembly, thus revealing the influence of assembly processes such as competition or environmental a…
Experimental assessment of insect pollination on rapeseed yield and oil quality in farmer’s field demonstrates positive effect of pollinator richness
2017
EAGESTAD DOCT INRA; Pollination is an ecosystem service on which humans depends through its link to food production. Some crops, e.g. oilseed rape (Brassica napus L.), are pollinated by a broad range of insects such as by honeybees, wild bees, and hoverflies. According to experimental studies, oilseeds rape production can be increased by 10-50% by insect pollination, however these results are often obtained by comparison between presence-absence of pollinators not with pollinators gradients. Moreover, no study has investigated the effect of pollinators on the oil’s fatty acid composition while rapeseed is cultivated for oil. Here, we quantified the contribution of insect pollination on rape…
