ALT Image containing seminar details and an Abstract of JF's talk, which starts: Ecosystem functions describe processes like biomass production, respiration, or nutrient cycling, that can be key to the livelihood of humans and other life forms. These functions are collectively performed by the many species that constitute an ecosystem; trees in a forest, plants in a grassland, or bacterial strains in a microbiome. Here, I will use linear algebra to show that generically, there is a sense in which a rare species can have as much importance as an abundant one. The reason why this claim is not obvious comes from the fact that in functional ecology, under the mass-ratio hypothesis, species contributions should be well predicted by their effect traits and abundance.
