New paper on urban forests

„Emerging Urban Forests: Opportunities for Promoting the Wild Side of the Urban Green Infrastructure“ has been published in Sustainability (free access). In this article we address opportunities associated with “emerging urban forests” such as spontaneously developing forests in cities for urban biodiversity conservation applying a multi-taxon approach.

New paper on spiders

„Spiders of dry grasslands in and around Berlin – diversity, distribution and endangerment“ has been published in Arachnologische Mitteilungen / Arachnology Letters. The article is open access.

We present the first comprehensive list for dry grassland spiders in Berlin and adjacent federal state of Brandenburg with 194 species including 33 endangered species and a new records for Berlin.

Biological traits and functional diversity in arachnology

Conference talk in Greifswald

Last weekend the conference of the German Arachnological Society took place in Greifswald. I gave a talk on trait-based approaches and functional diversity in arachnology and presented progresses and perspectives within this research topic (see slides). Trait-environmental relationships and functional diversity are very important components within biodiversity research and several studies have successfully applied these concepts to spiders. Unfortunately, a consensus how to select appropriate morpho-physiological, phenological and ecological traits and to define trait categories is missing yet. Therefore, my talk intended to encourage the development of a standardised and expert-based open-access trait database for spiders. It was great to have some fruitful discussions afterwards. We agreed on organising an expert workshop soon to work out a first proposal for a meaningful trait selection.

New paper on urban biodiversity

Biological richness of a large urban cemetery in Berlin. Results of a multi-taxon approach has been published in the Biodiversity Data Journal.

Urban green spaces can harbor a considerable species richness of plants and animals. A few studies on single species groups indicate important habitat functions of cemeteries, but this land use type is clearly understudied compared to parks. Such data are important as they (i) illustrate habitat functions of a specific, but ubiquitous urban land-use type and (ii)
may serve as a basis for management approaches. We sampled different groups of plants and animals in the Weißensee Jewish Cemetery in Berlin (WJC) which is one of the largest Jewish cemeteries in Europe. With a total of 608 species of plants and animals, this first multi-taxon survey revealed a considerable biological richness in the WJC. In all, 363 wild-growing vascular plant, 72 lichen and 26 bryophyte taxa were recorded. The sampling also yielded 34 bird and 5 bat species as well as 39 ground beetle, 5 harvestman and 64 spider species. Some species are new records for Berlin.
