Rarity has been a central topic for conservation and evolutionary biologists aiming to
determine the species characteristics that cause extinction risk. More recently, beyond the …

Conservation aims to preserve species and ecosystem services. If rare species contribute
little to ecosystem services, yet are those most in need of preservation, tradeoffs may exist …

There is broad consensus that the diversity of functional traits within species assemblages
drives several ecological processes. It is also widely recognized that rare species are the …

Reports of declines in biomass of flying insects have alarmed the world in recent years.
However, how biomass declines reflect biodiversity loss is still an open question. Here, we …

Identifying species that are both geographically restricted and functionally distinct, ie
supporting rare traits and functions, is of prime importance given their risk of extinction and …

The preservation of ecosystem processes under ongoing biotic erosion requires that some
species within affected communities perform similar functions, a property that is usually …

Foundation species define ecosystems, control the biological diversity of associated
species, modulate critical ecosystem processes, and often have important cultural values …

Ecological restoration of degraded ecosystems has emerged as a critical tool in the fight to
reverse and ameliorate the current loss of biodiversity and ecosystem services. Approaches …

Biodiversity continues to decline under the effect of multiple human pressures. We give a
brief overview of the main pressures on biodiversity, before focusing on the two that have a …

Global environmental change and increased human activities have led to rare species being
given vulnerable status, as well as species losses and extinctions in recent years. However …
