Seventy phytosociological releves were performed in 1 m x 1 m plots at 14 study sites spread along sandy shores in northern and southern Sardinia (Italy). The plots were selected in different habitat types (open dunes, native Juniperus woodlands, maquis, and plantations with Acacia, Eucalyptus and Pinus) according to a stratified sampling method in...
Article
The present study was undertaken to assess baseline distribution patterns for soil lichens occurring in the principal biomes of southern Africa, and to analyse their relationship to selected environmental parameters. Among the lichen species found across our survey sites, four distinct groups could be delineated, each as distinct consortium of lich...
Article
Elevated temperatures and diminished precipitation amounts accompanying climate warming in arid ecosystems are expected to have adverse effects on the photosynthesis of lichen species sensitive to elevated temperature and/or water limitation. This premise was tested by artificially elevating temperatures (increase 2.1-3.8°C) and reducing the amount...

2020 is a critical year for biodiversity. Despite the global pandemic, the process towards the adoption of a global biodiversity framework at the 15th meeting of the Conference of the Parties to the CBD, postponed to 2021, is progressing. In addition, 29 October 2020 marked 10 years since the adoption of the Nagoya Protocol on access and benefit-sh...

Full-text available
Die Bedeutung öffentlicher Grün- und Freiflächen für die Entwicklung zukunftsfähiger Städte ist grundsätzlich bei Politik und Gesellschaft anerkannt. Wichtig sind dabei der Erhalt und Schutz der Biodiversität im urbanen Raum, die Klimaanpassung als Antwort auf den Klimawandel und die Steigerung der Lebensqualität der dort lebenden Menschen. Der Bev...
Book
Die soziale, ökonomische und ökologische Bedeutung öff entlicher und halböff entlicher Grün- und Freifl ächen in den Städten ist lange bekannt, trotzdem sind diese weiterhin gefährdet; viele Kommunen sind wegen Mangels an Personal und Finanzmitteln, politischem Druck und steigendem Bedarf an Wohnraum kaum in der Lage, zum einen die erforderliche Öf...

Article
The epiphytic lichen diversity in and around the city of Pretoria (Tshwane, South Africa) has been investigated in 11 sites representing different land use types. Lichens were collected from three tree species: Jacaranda mimosifolia, Acacia karoo and A. caffra. Twenty-four taxa were recorded and are listed with notes on their ecology and distributi...

LIAS gtm, a new platform of the LIAS lichen information system, is presented. It allows for the visualization of phenotypic traits via geographic heatmapping of relative trait frequencies (RTFs) based on data derived from GBIF (occurrence data) and from LIAS light (taxon description data). The data are combined and referred to defined geographic ar...
Article
Similarly to other Mediterranean regions, Italy is expected to experience dramatic climatic changes in the coming decades. Do to their poikilohydric nature, lichens are among the most sensitive organisms to climate change and species requiring temperate-humid conditions may rapidly decline in Italy, such in the case of the epiphytic Lobaria species...
Article
This work describes the lichen diversity found on the megalithic Dolmen of Sa Coveccada (Mores, Sardinia) until 2010. After that year, a restoration with chemical removal of lichen crusts took place, which destroyed a great part of the lichen communities. These were studied again after removal and lichen communities occurring on rock outcrops in th...
Chapter
Biodiversity supports ecosystem functioning and productivity, and makes ecosystems more resilient and resistant to changes. Ecosystem functions are due to the biological, geochemical and physical processes occurring within an ecosystem. They relate to the structural components (e.g. water, soil, atmosphere, and biota) and their interactions within...

Over the past 12 years, the lichen trait database LIAS light as a component of the LIAS information system, has grown to a considerable pool of descriptive data based on 71 different qualitative, quantitative, and text characters, for nearly 10.000 lichen taxa, being phylogenetically arranged according to the MycoNet classification. It includes inf...
Article
Abstract Predicted elevated temperatures and a shift from a winter to summer rainfall pattern associated with global warming could result in the exposure of hydrated lichens during summer to more numerous temperature extremes that exceed their thermal thresholds. This hypothesis was tested by measuring lethal temperature thresholds under laboratory...
Conference Paper
Il presente lavoro descrive la diversità lichenica colonizzante fino a pochi mesi fa il dolmen di Sa Coveccada sito a Mores, nell’area nord-occidentale della Sardegna, e intende porre il problema di tutelare la biodiversità lichenica su tale tipo di monumenti sino ad ora poco considerati rispetto ad es. alla statuaria antica. Durante due primi sopr...
Article
The interception and evaporation of fog, dew and water vapour by soils and lichens in a coastal desert were measured with automated lysimeters at hourly intervals spanning a 12 month period. Fog water and lichen thalli were chemically analysed at monthly intervals. The chemical composition of the lichens did not correspond with the elemental concen...
Conference Paper
A database is an important tool for managing information on the specimens kept in natural history collections. The data gathered give not only information on specimens but also on the flora of a region and on its changes through space and time. The University of Sassari has created a database for the lichen specimens kept in SS herbarium. GBIF-2001...

A first characterization of soil-growing bryophyte and lichen communities along the coasts of Sardinia (Italy) is presented. The lichen Micarea melaenida is reported for the first time. Altogether, 5 different communities are reported: Group 1, dominated by Tortella flavovirens, Cladonia convoluta and Pleurochaete squarrosa; Group 2, close to the C...

Biodiversity is important for sustaining life on Earth yet it is threatened globally. The BIOTA Southern Africa project analysed the causes, trends, and processes of change in biodiversity in Namibia and western South Africa over nearly a full decade, from 2001 until 2010. This book, which is comprised of three volumes, offers a summary of the resu...

The lichen vegetation forming biological soil crusts is described for the first time for a semi-desert area of the Republic of South Africa (Knersvlakte, Namaqualand). Thirty-five terricolous lichen taxa were recorded. Fifty-two percent of the lichens are endemic to Namaqualand according to current knowledge. Squamulose and crustose lichens were th...
Article
The results of a thorough revision based on the morphological and chemical analysis of 885 Italian specimens attributed to the lichen genus Lepraria s.lat. are presented. Sixteen species of Lepraria s.str., Botryolepraria lesdainii and Lecanora rouxii are confirmed as belonging to the Italian lichen flora, and further two species (L. borealis, L. e...
Conference Paper
In plant invasion biology a great deal of efforts is going toward the assessment of impacts caused by exotic species. Un-wise forest management and the use of exotics have been frequently identified as potential threats to many forest species, particularly invertebrates and cryptogams. Epigeous bryophytes and lichens are important components of tem...

Artu in Sardinia (Italy) by mean of relevés carried out in different oak forest types, with the aim of pointing out differences due to anthropogenic activities. Altogether, 15 bryophyte species and 74 lichen species were found. Relevés were classified us...

Archived project
This Citizen Science project is addressed to children and youth. Teaching material was created as well as identification tables for 20 exotic species common in the Bonn region (Germany). Children and youth learn about neobiota and how to recognize exotic plants (neophytes). They collect actively occurrence data and images using an app (ArtenFinder). Gathered data are used by nature conservation authority and scientists (BUND - Bund für Umwelt und Naturschutz Deutschland NRW e.V.: www.bundforschtinbonn.de). Financially supported by the foundation "Stiftung Umwelt und Entwicklung NRW" (2014-2016)
