Lichens occur in most terrestrial ecosystems; they are often present as minor contributors,
but in some forests, drylands and tundras they can make up most of the ground layer …

This review is a first attempt to combine and compare spatial distribution of the three main
water sources, rain, dew and humid air, with water-related traits of mainly epiphytic …

Non-vascular vegetation has been shown to capture considerable quantities of rainfall,
which may affect the hydrological cycle and climate at continental scales. However, direct …

Although both lichens and bryophytes are all poikilohydric the groups seem to behave very
differently. Bryophytes also show a clear preference for wetter areas and this seems to be a …

1. The gelatinous cyanobacterial Collema tenax is a dominant lichen of biotic soil crusts in
the western United States. In laboratory experiments, we studied CO2 exchange of this …

1. Although the coastal fog zone of the Namib Desert has negligible rainfall, large parts may
be covered by soil-crust lichens with chlorophyll contents and photosynthetic rates (under …

Lichens and bryophytes are abundant globally and they may even form the dominant
autotrophs in (sub) polar ecosystems, in deserts and at high altitudes. Moreover, they can be …

This chapter discusses structural and physiological features of poikilohydrous autotrophs
and the different strategies in different ecological situations. It presents examples of …

Extensive investigations made in the past two decades on lichen photosynthesis in relation
to water content have shown two features of particular interest: first, the depression of net …
