Long-term demographic dataset for Cladonia perforata, including fine-scale cover, occupancy, and subpopulation area data, 2011-2024
This dataset includes all data pertaining to a long-term demographic study of Cladonia perforata (perforate reindeer lichen), a federally endangered lichen endemic to Florida, including fine-scale cover, occupancy, and population area data, conducted by the Archbold Biological Station Plant Ecology Program. This includes 13 years of data (2011-2024) from nine subpopulation (including seven at Archbold Biological Station, and two at the Lake Wales Ridge Wildlife and Environmental Area, Royce Unit), all located in rosemary scrub habitat within the Lake Wales Ridge metapopulation. This study sought to characterize the fire ecology and long-term population trends for the species, and thus also includes data on prescribed burn severity and time since fire. Data were collected using a stratified random plot design, with occupancy plots (presence/absence within 1.5 meter radius) throughout the subpopulation and a subset of these designated as cover plots only, with this cover data collected as point intercept hits within a 48x48cm area. Cover data also includes microhabitat data – canopy cover in densiometer reading and dominant ground cover. Cover and occupancy data were taken every 3 years for each subpopulation (subpopulations were on different yearly schedules). Subpopulation area was mapped using a submeter GPS unit every 6 years. Subpopulations were resampled for all metrics as soon as possible following a fire, and the sampling schedule was then reset.

Data from: The Wisdom of Fools: new molecular and morphological insights into the North American apodetiate species of Cladonia
The taxonomy of the North American apodetiate and superficially apodetiate species of Cladonia with persistent, primarily squamulose thalli (viz., C. apodocarpa, C. caespiticia, and C. petrophila) is revised using morphological, chemical, and ecological data in combination with molecular phylogenetic analyses of ITS1, 5.8S, and ITS2 sequence data. The results of this approach confirm some established taxonomic concepts in the group and raise doubts about others. The taxon known as C. apodocarpa is well supported by likelihood- and parsimony-based molecular phylogenetic inferences as well as morphology, chemistry, and ecology. However, molecular evidence gives an equivocal answer to the question of whether C. petrophila is a distinct monophyletic entity or if C. apodocarpa is nested within it. In addition, no phylogenetic structure is detected for the chemical races of C. petrophila with and without fumarprotocetraric acid, based on the markers used in these analyses. However, C. petrophila does remain well supported as a taxon by chemistry (i.e., the presence of sphaerophorin), morphology, and ecology. A morphologically and ecologically distinct new taxon is described as C. stipitata. We confirm the distant relationship of these taxa (C. apodocarpa, C. petrophila, and C. stipitata) to C. caespiticia, a species with stipitate or pseudopodetiate (vs. sessile) apothecia. A treatment of the North American apodetiate species of Cladonia including distribution maps, cited specimens, and illustrations is presented. A key to the taxa that includes unrelated, frequently sterile species of Cladonia found in eastern North America is also provided.
