„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.
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.
Implementing the Berlin Bee Strategy for conservation of bees and other pollinators in Berlin by optimising the protection of wild bees (funded bei Senatsverwaltung für Umwelt, Verkehr und Klimaschutz Berlin) – more info coming soon.
„Urbanisation modulates plant-pollinator interactions in invasive vs. native plant species“ has been published in Scientific Reports. The article is open access.
In this article, we show that invasive black locust (Robinia pseudoacacia) is a “pollinator-friendly” tree and attracts not only honey bees but also wild bees and other wild pollinators. However, we also found that attractiveness of black locust decreases with increasing urbanisation.
Recently, Märkische Entomologische Nachrichten has published two faunistic papers. The first one in on Carabid beetles (Coleoptera: Carabidae) of dry grasslands in Berlin (and Brandenburg). At 52 dry grassland sites in Berlin and Brandenburg we sampled 106 species including a new record for Berlin and numerous endangered species. The second one,
Wild bees of dry grasslands in Berlin, summarises bee data from 49 dry grasslands in Berlin. Both papers highlight the importance of urban sites as secondary habitats for rare and endangered invertebrates.
Assessing spider diversity in grasslands – does pitfall trap color matter? has been accepted in Journal of Arachnology.
Authors Möller M & Buchholz S
We analyzed effects of pitfall trap color (white, yellow, green, brown) on spider catches and found differences in alpha-diversity and one biological trait, namely hunting type. Attractiveness of different trap colors may arise due to differences in biological preconditions, albedo and microclimate which in turn can affect diversity and community structure of spiders. Trap color has a significant impact on spider catches and should be considered when planning surveys.
