Urban meadows as habitat for wild bees – new perspectives for pollinator diversity

Conference talk in Braunschweig

The German Society of general and applied Entomology (DGaaE) and the German Scientific Society for Plant Protection and Plant Health (DPG) organised a conference on insect diversity in cities (III. Urbane Pflanzen Conferenz). I contributed a talk on habitat function of urban meadows for wild bees with emphasis on urbanisation eurbane-pflanzen-conferenzffects (see Abstract in German). Due to a very diverse audience with many relevant stakeholders and decision-makers (e.g. scientists, gardeners, landscape planners, landscape architects, authorities and NGOs) it was possible to elaborate this topic from different perspectives. At the end we had very interesting – sometimes controverse – discussions to develop recommendations how to make cities more insect friendly and to comment on the new white book „Grün in der Stadt“ which was recently send out for preview. The official presentation of the white book will be in May 2017.

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.

Abstract
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.

New faunistic paper

Beitrag zur Heuschreckenfauna ausgewählter Trockenrasen in Berlin has been accepted for publication in Märkische Entomologische Nachrichten.

Summary
Grasshoppers of several dry and semi dry grasslands of Berlin have been sampled in 2011 and 2012. The study summarises the results and discusses the records of Calliptamus italicus, Oedipoda caerulescens, Phaneroptera falcata and Sphingonotus caerulans.
