Analysis of morphology, growth rate, and fragmentation of the endangered lichen species Cladonia perforata
by Witmer, David Warren, M.S., Florida Atlantic University, 2014, 89; 1527770
Abstract (Summary)

Cladonia perforata is an endangered lichen endemic to the Atlantic Coastal Ridge, Lake Wales Ridge, Southwest Florida, and the North Gulf Coast of Florida. In all but a single locality, C. perforata relies entirely on asexual reproduction through fragmentation for reproduction, dispersal, and recruitment. This study suggests a positive correlation between fragment size and survivability of fragments after one year. The average thallus grew at a rate of 10.42% per year and younger branches of a thallus grew at a quicker rate than older branches. Additionally, a review of thalli morphology suggests C. perforata has a diverse form, and becomes more bifurcated as it increases in size.
