This review summarises lichen work in the temperate Southern Hemisphere. A brief historical overview of austral lichenology is presented from the earliest European voyages of discovery up to the present day. Current knowledge is outlined for Australia, New Zealand, South Africa, southern South America, the Southern Subpolar islands, and Antarctica. Biogeographical patterns, and the importance of lichens in nutrient cycling, habitat restoration, and monitoring of global change, are also discussed from an austral perspective.

“…Mediterranean epilithic communities host a high diversity of organisms (e.g. >3000 lichen species in the Mediterranean region; Grube & Nimis ) that are differentially adapted to xeric conditions and selectively distributed across specific ecological micro‐niches. In epigeic and epilithic communities of poikilohydric organisms, many intra‐ and inter‐specific interactions occur at the micro‐scale (Hauck et al.…”

Question\ud Poikilohydric organisms can survive desiccation without damage and recover soon after re-wetting. In this work we explore the realized niches of epilithic, poikilohydric organisms, i.e. lichenized and lichenicolous fungi and bryophytes, grouped into 15 functional guilds based on growth form, reproductive strategy and photosynthetic traits. We hypothesize that in Mediterranean ecosystems, the distribution of these guilds is controlled by water availability and solar radiation, together with characteristics of the substrate.\ud \ud Location\ud Western Sardinia (Italy). The area hosts Mediterranean Quercus ilex forests on basaltic substrata within an agroforestry landscape.\ud \ud Methods\ud The presence or absence of species from each guild was recorded in 1025 small quadrats (10x10cm). Four environmental variables were measured: solar radiation, microtopography (potential water run-off), substrate roughness and number of cracks. The occurrence of each guild was related to environmental variables using non-parametric multiplicative regression, and ecological niches of the guilds were derived from those models.\ud \ud Results\ud The occurrence of all functional guilds varied significantly according to the selected environmental variables. In most cases, solar radiation was the most important variable; TI was included first in the model of two sorediate guilds, whereas four sexually reproducing functional guilds had surface relief as first variable. The growth forms were separated along a gradient of increasing solar radiation, whereas water run-off and surface roughness mainly discriminated reproductive strategies and photobionts. Vegetatively reproducing guilds with other photobionts than Euphyta-like pigments were confined to the border of the ecological space, defined by gradients of environmental factors, which was largely occupied by more competitive, sexually reproducing organisms.\ud \ud Conclusions\ud Functional traits of epilithic poikilohydric organisms were associated with ecological adaptations to the stressful environment of Mediterranean outcrops. We showed that their response in terms of probability of occurrence is coherent with quantitative gradients of solar radiation and water availability at the micro-scale

“…Few projects also employ the Internet as a production tool used by the authors to co-ordinate a project and to include the expertise of many scientists. Examples for such workspaces on the internet are the "Mediterranean checklist of lichens" (Grube & Nimis, 1997) and the "Plant Names Project" (Anonymous, 1998).…”

A method to establish and revise descriptive data sets over the Internet

In science, the internet is used at present mostly as an electronic publishing tool. It is highly desirable to increasingly use it as a working and production tool for collaborative projects in taxonomy and biodiversity as well. The method described here requires neither programming nor web-server expertise. Provided that the DELTA data standard is used, projects can be imported into the DeltaAccess database application. Using HTML data submission forms automatically generated from the database, projects can then be established and interactively revised over the internet. The forms permit adding new information as well as revising existing information. They are user-platform independent and require only standard web browser functionality. This standard-based approach avoids the repeated development of tools for using the internet as a working space. The DeltaAccess application is distributed over the internet under a General Public License.
