Diversity of Early-diverging Fungal Lineages in Temporary Ponds.

Temporary forest ponds, unique forest wetland habitats that annually dry out, serve as biodiversity hotspots and epicenters of evolution for many taxa. Amphibian, plant, and crustacean species associated with temporary forest ponds are relatively well studied. In contrast, little is known about the fungal communities upon which temporary pond food webs depend. This is especially true of early-diverging fungal lineages. We inventoried the chytrid biodiversity of a temporary forest pond in the Oakmulgee District of the Talladega National Forest using a combination of next generation sequencing and the traditional baiting and culturing approach. Specifically, we documented the phylogenetic diversity present and describe the temporal dynamics of that diversity. Preliminary data indicates that temporary ponds contain chytrid species typical of aquatic habitats as well as unique phylogenetic diversity and that the communities are temporally structured. Thus far, we can conclude that temporary ponds are a source of previously unknown chytrid biodiversity and represent an opportunity to examine the temporal dynamics of chytrid communities.
