Abstract
Traits related to reproduction and dispersal drive the assembly and
dynamics of species communities and can explain and predict how species
respond to habitat loss and fragmentation and to the changing climate.
For fungi, such links remain poorly known. We examine how spore
production rate, a key demographic trait, is influenced by the
interaction between environmental conditions and species traits. We
monitored the spore production of 97 wood-inhabiting fungal species on
107 decaying logs and analyzed the data with a hierarchical community
model. Our study shows that species display different seasonal and
diurnal release patterns, with important implications for dispersal. We
also provide the first quantitative evidence that fungi face the classic
trade-off of investing either in the number or size of offspring. We
provide new angles towards understanding different fungal life history
strategies, which have implications for species' ability to survive the
ongoing biodiversity crisis.
