The standing biomass is correlated with vegetation volume,  which describes plant biomass allocation within a complex canopy  structure. As the canopy structure of plant communities is not static  throughout time, it is expected that its changes also control diversity  effects on ecosystem functioning. Yet, most studies are based on one or  two measures of ecosystem function per year. Here, we examine the  temporal effects of diversity of grassland communities on canopy  structural components in high temporal (bi-weekly throughout the growing  season) and spatial resolutions as a proxy for ecosystem functioning.  Using terrestrial laser scanning, we estimate metrics of vertical  structure, such as biomass distribution (evenness) and highest biomass  allocation (center of gravity) along height strata. For horizontal  metrics, we calculated community stand gaps and canopy surface  variation. <\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" width=\"1024\" height=\"546\" src=\"\/wp-content\/uploads\/image-168-1024x546.png\" alt=\"\" class=\"wp-image-3867\" srcset=\"\/wp-content\/uploads\/image-168-1024x546.png 1024w, \/wp-content\/uploads\/image-168-300x160.png 300w, \/wp-content\/uploads\/image-168-768x409.png 768w, \/wp-content\/uploads\/image-168.png 1201w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p class=\"justify\">Our findings show that species-rich communities start filling  the vertical space (evenness) earlier in the growing season, suggesting  a more extended period of resource use (i.e., light-harvesting).  Moreover, more diverse communities raised their center of gravity only  at the peak of biomass in spring, likely triggered by higher  interspecific competition inducing higher biomass allocation at upper  layers of the canopy. Furthermore, richer communities were clumpier only  after mowing, revealing species-specific differences in regrowth.  Lastly, species richness strongly affected canopy variation when the  phenology status and height differences were maximal, suggesting  differences in plant functional strategies (space to grow, resource use,  and flowering phenology). Therefore, the effects of diversity on  ecosystem functions depending on those structural components such as  biomass production, decomposition, and herbivory, may also change  throughout the season due to various mechanisms, such as niche  differences, increased complementarity, and temporal and spatial  variation in biological activity. <\/p>\n\n\n\n<h4>Reference:<\/h4>\n\n\n\n<p class=\"justify\">Guimar\u00e3es-Steinicke C, Weigelt A, Ebeling A, Eisenhauer N, Wirth C.
