We are very pleased to announce our third online CESABINAR, which will take place on Friday October 18th at 3pm, Paris time. Cyrille Violle (CEFE, CNRS, Montpellier, France) will present the work of the FREE group on « Functional rarity: from detection to conservation » :
Rarity has always fascinated conservation and evolutionary biologists with the goal to uncover species characteristics causing extinction risk. Recently, some results suggest that rare species may over-contribute to the diversity of traits within communities thus supporting irreplaceable roles while others show that rare species are functionally redundant with common species. Beyond the rarity of species, the rarity of functions played by species, coined as functional rarity, is thus key to understand the impact of biodiversity decline on ecosystem functioning. However, functional rarity still lacks a clear definition and a quantitative framework while its emergence and maintenance within communities is largely unknown.
As part of the FRB-CESAB FREE working group, we have contributed to advance the concept of functional rarity and examine the causes and consequences of functional rarity from local to global scales. We showed that common assumptions notwithstanding, rare species can play unique and essential ecological roles, and that ecologically rare species are already more threatened by humans than ecologically common species and will be more impacted by future climate change. Finally, we highlighted that, in most taxonomic groups, hotspots of functional rarity differ from the areas where the most vulnerable species are found. This has major implications for species and ecosystem conservation where functional rarity appears to be an additional criterion to be considered urgently for the establishment of lists of so-called species at risk and for deciding on the location and size of areas to be protected.

The aim of these CESABINARS is to present the main results of the working groups once they finish a CESAB cycle. They last about 1 hour: 40 minutes of presentation and 20 minutes of questions, perhaps a bit more. The CESABINARs are open to the whole scientific community, to the participants of the CESAB groups and to the FRB network. They are a good opportunity to see how the CESAB groups work and what are their main results. They are in English, so don’t hesitate to promote them in your networks.
