Open AccessPhylogenomics reveals the evolutionary origins of lichenization in chlorophyte algae
Mutualistic symbioses have contributed to major transitions in the evolution of life. Here, we investigate the evolutionary history and the molecular innovations at the origin of lichens, which are a symbiosis...

Open AccessBiological scaling in green algae: the role of cell size and geometry
The Metabolic Scaling Theory (MST), hypothesizes limitations of resource-transport networks in organisms and predicts their optimization into fractal-like structures. As a result, the relationship between popu...

Open AccessNew lineages of photobionts in Bolivian lichens expand our knowledge on habitat preferences and distribution of Asterochloris algae
We studied the biodiversity of Asterochloris photobionts found in Bolivian lichens to better understand their global spatial distribution and adaptation strategies in the context of a worldwide phylogeny of the g...

Lessons from culturing lichen soredia
Vegetative propagules play various important roles in lichen biology. We cultured soredia of Cladonia lichens in vitro and obtained three noteworthy results. Firstly, soredia are a beneficial source for the isola...

Open AccessComparative plastid genomics of Synurophyceae: inverted repeat dynamics and gene content variation
The Synurophyceae is one of most important photosynthetic stramenopile algal lineages in freshwater ecosystems. They are characterized by siliceous scales covering the cell or colony surface and possess plasti...

Ecological and biogeographical drivers of freshwater green algae biodiversity: from local communities to large-scale species pools of desmids
Dispersal limitation, niche-based processes as well as historical legacies shape microbial biodiversity, but their respective influences remain unknown for many groups of microbes. We analysed metacommunity st...

Life cycle
Ulvophyceae exhibit a wide diversity of life cycles. Species may reproduce asexually, sexually, or exhibit a combination of sexual and asexual reproduction. Sexual reproduction involves a heteromorphic or isom...

Chapter
Phylogenetic position of the Ulvophyceae and evolutionary relationships among its main lineages
The Ulvophyceae are currently regarded as one of the main classes of the Chlorophyta, but the relationship of the class with other classes of Chlorophyta is still a matter of debate. Also the relationship amon...

Genus classification
Circa 110 genera of ulvophytes are currently circumscribed, most of which are restricted to the marine environment. Although most of the traditionally circumscribed genera are easily distinguishable based on g...

Taxonomic, ecological, and geographic scope of this book
This book is in intended to provide a comprehensive overview of Ulvophyceae species diversity in freshwater and (aero)terrestrial habitats in Europe, and a tool for identification of the species, up to the lev...

Circumscription of the class Ulvophyceae: ultrastructure and morphology
The Ulvophyceae K. R. Mattox & K. D. Stewart is one of the main classes of green algae, comprising about 1700 species according to AlgaeBase (Guiry 2012, Guiry & Guiry 2017). Most of this diversity is found in...

Ecology of freshwater and terrestrial ulvophytes
Although the largest diversity of Ulvophyceae is found in marine habitats, a substantial number of species may be found over a broad salinity range, and occur in brackish to freshwater and semi-terrestrial hab...

Chapter
Classification: orders and families
Current classification of the Ulvophyceae includes 32 families in 8 orders (Leliaert et al. 2015). The present study significantly revises the classification of ulvophytes, in particular the Ulvales and Ulotri...

Collection, preservation and culturing
Macroscopic freshwater ulvophytes, including Cladophora and Ulva species, are easily observable and collectable. For these species, thalli can be preserved as dried herbarium specimens, or as wet specimens in ...

Chapter
Glossary
Aerophytic – plant or alga that derives moisture and nutrients from the air and rain; usually growing on other leaves or stems of plants, but also on other substrates such as rocks.

Systematic part
Thalli microscopic or macroscopic, including filamentous, pseudoparenchymatous, tubular or blade-like forms, attached, free-floating, endophytic or shell-boring. Cells uni- or multinucleate, generally possessi...
