Rock surfaces provide a challenging habitat for a broad diversity of micro- or small-sized organisms. They interact with each other forming complex communities as well with their substrate causing biodeterioration of rock. Extreme fluctuation in light, temperature and hydration are the main factors that determine the rock surface habitats. The habitat includes epilithic organisms which thrive on the surface without penetrating the rock, endolithic organisms which live just beneath the surface using a thin layer of the rock surface for protection against adverse conditions of the environment (e.g. light protection, storage of water) and chasmo-endolithic organisms which use fractures of the rock surface for a more habitable environment. The book will provide an overview of the various organismal groups, from prokaryotes to vascular plants and arthropods, as well as survey organism-mediated interactions with the rock surface. The latter include biogenic weathering (biogeochemistry, state-of-the art imaging methods), photosynthesis and nitrogen fixation at and inside the rock surface.

Gottfried Dietrich Wilhelm Berthold (1854-1937) was one the foremost botanists and phycologists at the end of the 19th century. Born and educated in Westphalia, he enrolled at the Georgia Augusta to study plant sciences and focused on algae. After research stays at the Zoological Station at Naples he succeeded his mentor Johannes Reinke on his chair at the Institute of Plant Physiology at the Georgia Augusta Göttingen until 1923. In this study we focus on the biography of Berthold, his private and scientific life, interaction with J. Reinke and other topics related to the life of Berthold. In a second part we highlight his research on algae at the Gulf of Naples. We conclude with an evaluation of his scientific work in the light of the different phases in his life including a full bibliography of his scientific publications. Our study contributes to history of science at the Georgia Augusta. Der aus Westfalen stammende Gottfried Dietrich Wilhelm Berthold (1854- 1937) ist als Botaniker des 19. und beginnenden 20. Jahrhunderts eng mit der Geschichte der Georgia Augusta in Göttingen verwoben. Er hatte sich bereits als Student an der Universität Göttingen mit Algen beschäftigt und seine Dissertation dieser Thematik gewidmet. Nach Forschungsaufenthalten an der Zoologischen Station in Neapel, wo er intensiv Untersuchungen an Algen durchführte, habilitierte er sich 1881 in Göttingen bei Johannes Reinke. Später übernahm er dessen Professur für Botanik sowie dessen Direktorat am Pflanzenphysiologischen Institut und widmete sich entwicklungsmechanischen bzw. physiologischen Fragen bei höheren Pflanzen. Die vorliegende Monografie untersucht erstmalig anhand der gegenwärtigen Forschungslage Leben und Wirken Bertholds. Bertholds Lebensgeschichte wird chronologisch und in größtmöglicher Vollständigkeit dargestellt. Bildungsgeschichtliche Akzente, der personelle Konnex zu Johannes Reinke und der Einfluss der Zoologischen Station Neapel finden hier ebenso Platz wie die Rekonstruktion der Lehr- und Forschungstätigkeiten und der familiären Verhältnisse. Da Berthold vorrangig als Phykologe, also Algenkundler anzusehen ist, widmet sich der zweite Teil dem Forschungsschwerpunkt Algen. Dabei werden vor allem die meeresbiologischen Aspekte seiner Forschung am Golf von Neapel untersucht. Bertholds unterschiedliche Lebensstationen können in Zusammenhang mit seinen Publikationen betrachtet werden, dieser Teil untersucht daher das wissenschaftliche Wirken Bertholds. Anhand der aktuellen Quellenlage wird der Bestand seiner Werke aufgearbeitet und katalogisiert. Die vollständige Bibliografie ermöglicht die Bestimmung von Schwerpunkten in Bertholds wissenschaftlichen Untersuchungen. So bietet diese erste Monografie über Gottfried D.W. Berthold ein Fundament für die Beurteilung seines OEuvres und seiner Wirkung auf die Phykologie bzw. die Botanik. Sie ist eine angemessene Erinnerung an ihn und ermöglicht eine gebührende Würdigung seines Wirkens. Die vorliegende Studie ist ein Beitrag zur Universitäts- und Wissenschaftsgeschichte der Georgia Augusta.

As a reader of this book you will become familiar with current, up-to-date comprehensive knowledge about all classes of eukaryotic algae, the cyanobacteria, and symbiotic interactions of algae and cyanobacteria with other organisms. For example, the lichens are symbiotic consortia and a prominent example of a particularly successful ‘evolution by cooperation’. We expand even to the beginnings of terrestrial plant life and the bryophytes, which are gradually transmitting to the vascular plants. We collectively call this enormous phylogenetic wealth of photoautotrophic organisms the ‘new cryptogams’, abandoning the traditional definition of cryptogams. The new cryptogams are all those autotrophic organisms that share being hydro-passive, meaning that they are unable of controlling water uptake or release, in contrast to vascular plants. While being basal of and phylogenetically much more diverse than the vascular plants, the new cryptogams are ecologically highly relevant in all ecosystems of our Planet. They are responsible for more than half of the Earth’s annual oxygen production. The editors Burkhard Büdel, born in 1953, with courses of studies in chemistry and biology at the universities of Darmstadt and Marburg/Lahn, received his doctoral degree from the latter in 1986. Habilitation at the university of Würzburg in 1993. Professorships at the universities of Rostock (1995-1997) and, until retirement (2019), Kaiserslautern. Exploring expeditions to all continents, including both polar regions. Major research fields: ecology and ecophysiology of cyanobacteria, algae, lichens, and bryophytes; systematics and taxonomy of cyanobacteria and lichens. Thomas Friedl, born in 1960, with courses of studies in biology at the universities of München, Marburg/Lahn, and Bayreuth, received his doctoral degree from the latter in 1989, is professor at the Georg-August-Universität Göttingen since 1999. There he teaches about algae, performs research in the fields of biodiversity, systematics, and culture maintenance of algae and cyanobacteria. He is the scientific director of the renowned culture collection of algae at the university of Göttingen (SAG). Wolfram Beyschlag, born in 1953, with courses of studies in chemistry and biology at the universities of Kiel, Erlangen-Nürnberg and Würzburg. Doctoral degree (1985) and habilitation (1990) at the university of Würzburg. Since 1994 full professor for Experimental and Systems Ecology at the university of Bielefeld. Retired in 2019. Several research projects in the Mediterranean, the Western US, and the Central American Tropics. Main research topics: physiological ecology of higher plants and cryptogams, plant-plant and plant-animal interactions, ecological modelling. Long-term teaching experience on mosses and lichens. .
