Introduction
I am an ecologist with a special interest in entomology and vegetation science. My fields of research cover different aspects of conservation biology and community ecology. I use plants, grasshoppers, butterflies, leafhoppers and dragonflies as model organisms because they are excellent ecological indicators. Currently, I am analyzing the effects of land-use change and global warming on species diversity.

Article
Land-use change has caused degradation, loss and fragmentation of semi-natural habitats, especially in grassland ecosystems. Today, the remaining habitats are often situated in a matrix of intensively used agricultural land and are therefore more or less isolated from each other. Connectivity, area and quality of habitat patches have been identifie...
Article
Semi-natural grasslands are among the most species-rich ecosystems worldwide. However, the maintenance of grassland biodiversity is seriously threatened by land-use change. Additionally, climate change is increasingly affecting biotic communities in grasslands. In this study, we examine Orthoptera community shifts in response to land-use and climat...

Aim: Stopping the decline of biodiversity is one of today’s greatest challenges. To help address this, we require studies that disentangle the effects of the most important drivers behind species range losses and shifts. In this large-scale study, we aim to evaluate the relative impacts of changes in land use and climate on distributional changes i...
Article
Open and unreclaimed quarries often host species-rich plant and animal communities. However, the specific factors that determine biodiversity in such anthropogenic habitats are largely unknown. This applies in particular to diverse groups of insects. We therefore studied bee assemblages of 16 limestone quarries, eight active and eight abandoned one...
Article
Full-text available
Land-use and climate change are considered the major drivers of recent insect loss. Orthoptera (hereinafter termed ‘grasshoppers’) are the main arthropod consumers in grasslands and, hence, are important elements for supporting ecosystem services. However, for intensively-used agricultural landscapes, it is largely unknown to what extent both facto...

Der Lebensraum „Kalkmagerrasen“ zeichnet sich v...
Article
Full-text available
Recent climate and land-use changes are having substantial impacts on biodiversity, including population declines, range shifts, and changes in community composition. However, few studies have compared these impacts among multiple taxa, particularly because of a lack of standardized time series data over long periods. Existing data sets are typical...
Article
Full-text available
Orthoptera (hereinafter termed ‘grasshoppers’) are of great functional significance since they are the main arthropod consumers in grasslands and an important food source for medium‐sized insectivorous vertebrates. However, research investigating the effects of extreme weather events on the abundance of grasshoppers has lacked thus far. Here, we st...

Article
Since the beginning of the industrial era, humankind has altered the environment at an unprecedented rate, causing a dramatic loss of biodiversity. Recent studies have revealed that extinction events often occur with a time delay. In ecology, this phenomenon is termed extinction debt. Here we give an overview of the concept of extinction debt and i...

An important component of recent nature conservation is the ecological restoration of semi‐natural grasslands. The aim of such projects is usually the restoration of typical plant communities; translocation of animals, by contrast, plays only a minor role. This is based on the assumption that a recovery of the flora will lead to recovered fauna; ho...
Article
The biodiversity in calcareous grasslands suffered from severe habitat loss due to land-use intensification and abandonment across Europe. Although these grasslands are now protected under the EU Habitats Directive, many species in the remaining habitat patches are still declining. Recent studies suggest that species across different taxa may becom...
Article
Land-use change has been identified as the most important factor responsible for the recent loss of biodiversity. One major problem is the abandonment of management, especially in semi-natural grassland ecosystems. Numerous restoration projects were, therefore, launched to counteract this development. However, the effects of restoration are not yet...

Article
Habitat specialists living in metapopulations are sensitive to habitat fragmentation. In most studies, the effects of fragmentation on such species are analyzed based on Euclidean inter-patch distances. This approach, however, ignores the role of the landscape matrix. Recently, therefore, functional distances that account for the composition of the...

Long-winged (macropterous) individuals that are capable of flight in predominantly short-winged (flightless) species can considerably affect population dynamics and range expansion. Understanding the triggers that determine macropterism is crucial for understanding whether the dispersal ability of species allows them to shift their distributions through fragmented landscapes or in response to climate change. Within this long-term project, we studied population densities and wing dimorphism (macroptery) of Roeseliana (Metrioptera) roeselii and Metrioptera brachyptera.
