Species delimitation in composite organisms: the value of recognizing species boundaries in lichen symbionts

Leavitt, Steven [1].

Species delimitation in composite organisms: the value of recognizing species boundaries in lichen symbionts.

While lichens represent an iconic example of symbiosis, interactions among lichen symbionts are often masked by uncertain species boundaries or inability to reliably identify symbionts. The goal of this colloquium is to explore species discovery and identification in both myco- and photobionts, and the implications of improved species boundaries for enhancing our perspective on lichen symbioses. Coupled with the increased availability of molecular data, a number of recently developed methods offer exciting approaches to explore species delimitation and specimen identification in lichen symbionts. We aim to included research on integrative species delimitation, the role of morphological characters for recognizing species boundaries, how to incorporate genomic data into species delimitation research, sequence-based identification, and more. Finally, we hope to fill the gap between simply recognizing species boundaries and what it means for understanding symbiotic systems by exploring patterns of symbiont interactions in lichens.
