Have a look at the publications. Three articles have been accepted in the last weeks. One article is a review on Functional ecology of wild bees in cities. Then there is a new text on ground beetles in riparian habitats, in which we compare the carabid diversity of nature and human impacted riparian habitats and set the baseline for future renaturation. Most recently there is a text on the relationship between birds and insects in urban areas.
„A multidimensional framework for measuring biotic novelty: How novel is a community?“ has been published in Global Change Biology. This paper introduces the Biotic Novelty Index, an intuitive and flexible multidimensional measure that combines (a) functional differences between native and non‐native introduced species with (b) temporal dynamics of species introductions.
„Functional ecology of wild bees in cities: towards a better understanding of trait-urbanization relationships“ has been published in Biodiversity and Conservation.
In this paper, we summarize the published literature in the growing field of wild bee functional ecology and review which functional trait-based analyses have been carried out on wild bees in cities thus far, summarize which wild bee species traits have been considered and evaluate any consistent wild bee trait–environment relationships across studies.
Recently, two articles were published in the journal ‚Sustainability‘. Both are open access and can be downloaded from the publications page.
„CityScapeLab Berlin: a research platform for untangling urbanization effects on biodiversity“
„Clean, green urban wetlands benefit nocturnal flying insects and associated insectivorous bat predators“
„Spiders in Galapagos – diversity, biogeography and origin“ has been published in the Biological Journal of the Linnean Society. In this paper we present an up-to-date list of species of spiders of Galápagos. We also analysed the Galápagos spider fauna in terms of distribution within the archipelago and origin. Based on this, we discuss the mode of arrival, dispersal patterns and colonising abilities of the spider families and species found in Galápagos .
„Wild bees in urban grasslands: Urbanisation, functional diversity and species traits“ has been published in Landscape and Urban Planning. We found that urbanisation was not related to neither taxonomic nor functional diversity in bee communities of urban grasslands. However, endangered bee species responded negatively to the isolation of grasslands but positively to flower coverage. Urbanisation, previous restoration efforts and site type filtered the functional composition of bee communities in terms of species traits related to diet and nesting. Our results substantiate the role of urban habitats for functionally diverse bee communities, including rare and endangered species, and indicate pathways towards enhancing habitat functions of urban grasslands for wild bees by improving the connectivity of urban grassland patches within the urban matrix, and more locally by adjusting management to maintain flower coverage in grasslands.
„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.
„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.
One of the main objectives of our project is to analyse interactions between honey bees and wild bees (and other wild pollinators) in urban habitats. Of particular interest is the question of whether there is food competition between honey and wild bees and which role environmental conditions – such as amount of flowering plants – play. We are currently conducting experiments to answer this question.
We are launching a new research project to analyse wild boar effects on habitats, plant and insect biodiversity and sand lizard populations. This project is funded by Stiftung Naturschutz Berlin and will start in September 2019.
