Estimating the timescale of Lobaria diversification
Using an ITS mutation rate as calibration reference, a three-locus timetree was generated and gave an estimate of the diversification time for Lobaria during the early Oligocene, indicating that the paleoclimate and the closing or opening of the Bering Strait played a major role in shaping the current distribution of most Lobaria species.

The genus Lobariella (Ascomycota: Lobariaceae) in Hawaii: late colonization, high inferred endemism and three new species resulting from “micro-radiation”
All three species of Hawaiian Lobariella are very closely related, forming a well-supported, monophyletic clade in spite of their morphological differences, suggesting local micro-radiation. Expand
Peter D. Crittenden: meta-analysis of an exceptional two-decade tenure as senior editor of The Lichenologist, the flagship journal of lichenology
Abstract Peter D. Crittenden served as senior editor of The Lichenologist, the flagship journal in the field of lichenological research, for a period of two decades, between 2000 and 2019. A reviewExpand
Diversity and ecological adaptations in Palaeogene lichens
The fossil lichens show a wide diversity of morphological adaptations that attached epiphytic thalli to their substrates, helped to combine external water storage with effective gas exchange and facilitated the simultaneous reproduction and dispersal of both partners in symbiosis. Expand
Microbial communities of lichens
The reviewed literature enabled us to consider the growing and decaying thallus as a complex ecosystem with specific levels of regulation of abundance, taxonomic diversity, and activity of the members of five kingdoms: fungi, plants, protozoa, eubacteria, and archaea. Expand
Glacial refugia and the prediction of future habitat coverage of the South American lichen species Ochrolechia austroamericana
The aim of this study was to determine localization of glacial refugia of South American Ochrolechia austroamericana and to estimate the future changes in the coverage of its habitats using ecological niche modeling tools. Expand
Microbes and the Fossil Record: Selected Topics in Paleomicrobiology
Studies of the microbial fossil record are relevant to profound, perennial questions that have puzzled humanity and science—they provide the only direct window onto the beginnings and early evolution of life; and the methods and criteria developed for recognizing ancient, inconspicuous traces oflife have yielded an approach directly applicable to the search for traces of life on other worlds.

Evolution, the compartmentalization of habitats, and delineation of a species niche, function in a coordinated way and have unifying commonality in that each generally can be perceived as a balanceExpand
10 Fungal Diversity in the Fossil Record
This chapter includes examples of fossil fungi from each of the major lineages and describes the current level of information about their morphology, biology, and evolution and provides some directions for future studies of fossil fungus and identifies some questions that only the fossil record can answer.

Lichen preservation in amber: morphology, ultrastructure, chemofossils, and taphonomic alteration
Light microscope, scanning electron microscopy, and energy dispersive X-ray spectroscopy are applied to an amber-preserved Eocene lichen in order to gain information about the preservation of the fossil. Expand
