Introduction to the Festschrift dedicated to Professor Eva Barreno Lucia Muggia 1
# Springer Nature B.V. 2020
This special issue is centered on lichens because they have been the main focus of the scientific career of Professor Eva Barreno, to whom the issue is dedicated, on occasion of her 70th birthday, and in recognition of her contributions to lichenology. This Festschrift issue gathers original researches covering many aspects of the lichen symbiosis. The traditional view of lichens as symbiotic phenotypes, originating from the interactions of a single fungal partner and one or few photosynthetic partners, has been extended in recent years. There have been several discoveries which uncovered an unexpected complexity and diversity in the lichen symbiotic system. The issue begins with a tribute to Eva Barreno’s scientific and academic career, and this is followed by twelve scientific contributions. The short biography with two anecdotes was prepared by Ana Crespo, Pradeep Divakar and Arnoldo Santos, Eva’s friends and colleagues. They provide a remarkable and valued portrait of the chapters in Eva Barreno’s professional life.

The twelve contributions, herein, range from the traditional approaches to studying lichen diversity and their physiology, by means of morpho-anatomical analyses using light and electron microscopy, culture isolations and phylogenetic systematics, to the most modern sequencing techniques and development of computer-aided key to facilitate species recognition. The studies on lichens, and their individual symbiotic fungal and algal partners, reveal diverse ecologies, growth forms and genetic diversity worldwide. In addition, there are peculiar physiological responses to different environmental conditions that are models for the study of symbiosis. Pino-Bodas et al. use distribution models based on several algorithms to estimate the potential distribution of C. subturgida, an overlooked Mediterranean species, that is apparently restricted to the Iberian Peninsula and Canary Islands, but there may be regions with suitable climatic conditions where it has not been reported yet. Another lichen whose range includes the Canary Islands is described by Moya et al. who apply a multidisciplinary approach to describe the diversity of the photobiont genus Trebouxia in a peculiar, circumMediterranean/Macaronesian lichen species. This is Buellia zoharyi, that usually occurs in semi-arid areas in these islands. Garrido-Benavent et al. explore the amphitropical phylogeographic structure of the green algae that are involved in the symbiosis with species in the genus Pseudephebe (Parmeliaceae), including those found in Arctic and Antarctic regions. The endemic Antarctic species Himatormia lugubris has been investigated by Sancho et al. to elucidate which functional strategy, possibly linked with thallus anatomy and the distribution of the photosynthetic a
