Introduction
My main research interests are macroecology, conservation biogeography, and biodiversity informatics. Current projects focus on regional to global patterns of land plant diversity and their implications for nature conservation. I am interested in different aspects of global change: both in studies of Latin American (especially Andean) ecosystems as well as in local assessments of Central European landscapes. My teaching at the undergraduate level includes all aspects of organismic botany and vegetation ecology. At the graduate level I have been working with a wide range of international students – both in the context of our own MSc programs as well as in international summer schools. This includes the use of GIS and R in the context of macroecology and conservation biogeography.

Full-text available
In this study we aim at refining our understanding of the floristic connectivity of the loma-and precordillera floras of southern Peru and northern Chile and the parameters determining vegetation cover in this region. We used multivariate analyses to test for floristic-and environmental similarity across 53 precordillera and loma locations in Peru...
Article
Disjunct clades between the southern and the tropical Andes represent a biogeographical pattern that has not been studied. One of the plant groups showing this disjunction is the clade formed by the genera Archidasyphyllum, Arnaldoa and Fulcaldea (Asteraceae, Barnadesioideae). Archidasyphyllum is distributed in central and southern Chile and adjace...
Chapter
Several plant clades show a characteristic disjunction between the southern Andes (SA) and southern Brazil (SB). This disjunction has been explained by Neogene geologic and climatic changes, especially due to the Andean uplift, the Mid-Miocene marine transgressions, and the development of Patagonian aridity. We compared phylogeny-derived divergence...

The tropical Andes in South America are a global centre of plant diversity, housing an estimated 50,000 vascular plant species. Unfortunately, our knowledge about the mesoscale patterns of plant diversity within this region is still rudimentary. We use the currently available floristic checklists and a plant distribution dataset downloaded from the...

Article
The impact of Pleistocene climate changes substantially varied between tropical regions, resulting in striking differences in angiosperm species richness caused by post-glacial recolonization delays. Tropical bryophytes, which have been perceived as extremely good dispersers due to biased rates of monoecy and hence spore production, differ striking...
Article
Autogamous species are usually distinguishable from xenogamous relatives by smaller flowers, fewer or even no floral rewards and lower pollen–ovule (P/O) ratios. Many Rhipsalis spp. are small flowered, selfing and include the most widespread species in Cactaceae. However, Rhipsalis also includes a large number of narrowly endemic species and is mos...

The Cactaceae with c. 1,435 species are the most important plant family of the arid regions of the Americas. Recent revisions and molecular studies resulted in an improved knowledge of the phylogeny and taxonomy of this group. Due to their high value as ornamental plants, countless publications with data on ecological preferences and geographic occ...

The tropical Andes are a hotspot of biodiversity, but detailed altitudinal and latitudinal distribution patterns of species are poorly understood. We compare the distribution and diversity patterns of four Andean plant groups on the basis of georeferenced specimen data: the genus Nasa (Loasaceae), the two South American sections of Ribes (sect. Par...

We summarize research on the global centres and gradients of vascular plant diversity. Most centres of plant species richness are located in geodiverse areas of the humid tropics and sub-tropics, especially in forest biomes. When focussing on the rarity of the flora, islands play an outstanding role. Endemism-scaled richness of oceanic island flora...

We analysed documented moss species numbers on a global scale with the aim to identify regions or countries with possibly under-documented moss floras. European units (countries, administrative units) in general have much higher documented species numbers than extra-European units with similar area sizes. Especially South American and African units...
Article
Full-text available
Pteridophytes (ferns and fern-allies) represent the second-largest group of vascular plants, but their global biogeography remains poorly studied. Given their functional biology, pteridophytes are expected to show a more pronounced relation to water availability and a higher dispersal ability compared to seed plants. We test these assertions and do...

Full-text available
Climate change represents a major challenge to the maintenance of global biodiversity. To date, the direction and magnitude of net changes in the global distribution of plant diversity remain elusive. We use the empirical multi-variate relationships between contemporary water-energy dynamics and other non-climatic predictor variables to model the r...

Article
Full-text available
Endemism and species richness are highly relevant to the global prioritization of conservation efforts in which oceanic islands have remained relatively neglected. When compared to mainland areas, oceanic islands in general are known for their high percentage of endemic species but only moderate levels of species richness, prompting the question of...
Article
Full-text available
In both ecology and conservation, often a strong positive association is assumed between the diversity of plants as primary producers and that of animals, specifically primary consumers. Such a relationship has been observed at small spatial scales, and a begetting of diversity by diversity is expected under various scenarios of co-evolution and co...

Vascular plants are often considered to be among the better known large groups of organisms, but gaps in the available baseline data are extensive, and recent estimates of total known (described) seed plant species range from 200000 to 422000. Of these, global assessments of conservation status using International Union for the Conservation of Natu...

The diversity of vascular plants is very unevenly distributed across the globe. The five centres that reach species richness of more than 5,000 spp./10,000 km2 (Costa Rica-Chocó, Atlantic Brazil, Tropical Eastern Andes, Northern Borneo, New Guinea) cover only 0.2 % of the terrestrial surface. On the other hand approximately 18,500 spp. are endemic...
