Growth Rates of Xanthoparmelia Lichens in North Cemetery, Petersham MA 2005-2011
Lichens fix carbon dioxide from the air to build biomass. Crustose and foliose lichens grow as nearly flat, circular disks. While smaller lichens grow slowly, but with small, steady increases in radial growth rates, larger lichens grow more quickly, with radial velocities that remain roughly constant over the lifetime of an individual. These basic features follow directly from a novel mathematical model based on the diffusion of carbon dioxide around a lichen, and its absorption by the thallus. Smaller lichens fix carbon dioxide across the entire thallus, but larger lichens fix carbon dioxide disproportionately at edges. Because local edges remain the primary source of carbon as a lichen grows ever larger, radial growth rates remain constant. Predicted growth dynamics depend on four measurable parameters, and tests of the model against data suggest the model provides an accurate, robust, and universal framework for understanding the growth dynamics of lichens in nature.

FIGURE 1. The 50% majority-rule consensus tree of the molecular phylogenetic relationships of South Korean Xanthoparmelia species, based on 18000 trees from a B/MCMC tree-sampling procedure of ITS ribosomal DNA dataset of the "focal-group". Posterior probabilities ≥ 0.50 are given above the branches, and values below the branches are ML bootstrap values ≥ 50%. Branches that received strong support in any of the two analyses (≥ 70% in RaxML and ≥ 0.95 in B/MCMC) are in boldface.

Figure 2 Phylogenetic relationships of the Xanthoparmeliamexicana group based on a concatenated data set of ITS, mtSSU, nuLSU and MCM7. Topology based on maximum likelihood (ML) analyses. Bootstrap values above 75 and 0.95 posterior probability are indicated on each branch. The clades I, II and III are highlighted in blue, yellow and pink, respectively. Selected specimens representing clades (habit and isidia): I, X.mexicana s. lat. (A, B); II, X.pedregalensis (C, D) and III, X.mexicana s. str. (E, F), a picture of the X.mexicana type specimen from BP is included (G).
