Complex socio-economic, political and demographic factors have driven the increased conversion of Europe’s semi-natural grasslands to intensive pastures. This trend is particularly strong in some of the most biodiverse regions of the continent, such as Central and Eastern Europe. Intensive grazing is known to decrease species diversity and alter th...

Annual report of the Citizen Science project Butterfly Monitoring Germany

In the face of global pollinator decline, extensively managed grasslands play an important role in supporting stable pollinator communities. However, different types of extensive management may promote particular plant species and thus particular functional traits. As the functional traits of flowering plant species (e.g., flower size and shape) in...

Insect conservation needs sound information on species distribution trends. Developing this evidence relies—in practice—on long-term engagement of volunteers who observe and record species over large spatial and temporal scales. Many biodiversity monitoring schemes, including those for insects, are highly dependent on conservation-based citizen sci...

Anthropogenic environmental change disrupts interactions between plants and their animal pollinators. To assess the importance of different drivers, baseline information is needed on interaction networks and plant reproductive success around the world. We conducted a systematic literature review to determine the state of our knowledge on plant–poll...

This technical report describes the collection of data for an assessment of the multivariate relationships between a group of parameters and the distribution of butterflies over Butterfly Monitoring Transects. The results can be used for the development of future scenarios to investigate the effects on biodiversity, and butterflies in particular.

Fließtext Anthropogenic environmental changes threaten biodiversity as well as interactions between trophic levels and consequently alter ecosystem functions. A new experimental research platform, the „iDiv Ecotron“, was developed to investigate the mechanisms underlying the relationship between biodiversity and ecosystem functioning by manipulatin...

This report presents the fifth version of the European Grassland Butterfly Indicator, one of the EU biodiversity indicators of the European Environment Agency. The indicator is based on national Butterfly Monitoring Schemes in 22 countries across Europe, most of them active in the European Union. Fluctuations in numbers between years are typical fe...

Das Tagfalter-Monitoring Deutschland (TMD) ist ein sog. Citizen Science-Projekt, bei dem ehrenamtliche Zähler regelmäßig entlang von über 300 Strecken im Bundesgebiet Tagfalter erfassen. Die Zählungen werden seit 2005 jedes Jahr in der Zeit von April bis September auf denselben Strecken (=Transekten) durchgeführt. Mittlerweile steht ein sehr umfang...

In 2005 a nationwide monitoring scheme for butterflies (and diurnal moths) was launched in Germany. Coordinated by the Helmholtz Centre for Environmental Research-UFZ, it started as an integral part of the public relations campaign "Abenteuer Schmetterling" (Adventure Butterfly) with German public television and an environmental NGO as partners. Th...

Zusammenfassung: Im vorliegenden Beitrag werden drei verschiedenartige Projekte bzw. Initia- tiven aus dem Bereich der Biodiversitätsforschung vorgestellt, die alle einen engen Bezug zur Entomologie - meist zur Schmetterlingskunde - haben. Diese Projekte (MacMan, ALARM und TMD = Tagfalter-Monitoring Deutschland) werden zusammenfassend charakterisie...

Frozen frog legs that had been shipped from Indonesia into the European Union were biochemically compared to reference muscle samples from wild Indonesian frog populations of different species. Frozen frog leg samples only allowed for the analysis of eight allozyme loci, two of which were polymorphic. The analyses clearly showed that all frog legs,...

For a regional and spot analysis of heavy-metal data from agricultural soils in the German states of Saxony (Sachsen) and Sachsen-Anhalt, in a project named REGNAL, the following data were available: the soil data base of the State Office of Environmental Protection in Sachsen-Anhalt (selected data), soil data on heavy metals for Querfurt county, h...

The study outlines methods to assess population sizes of animals, in particular invertebrates, for the fields of population ecology and nautre conservation. It presents both wide-spread, well established methods and more recent approches. A more comprehensive version of the study, including arithmetical examples and a detailed description for the a...

After the German re-unification in 1990, 44 open cast coal-mines were abandoned in East-Germany. Today only 50% (400 km2) of the areas affected by mining activities have been recultivated. The open cast mines in East Germany represent last refuges for many endangered animal species. These species will disappear if future recultivation does not cons...

Die eingehende Analyse der Umweltbelastungen und der Landnutzungssituation in der Modellregion Leipzig-Halle-Bitterfeld bildet die Grundlage dieses Buches. Neben der Einschätzung des Gefährdungspotentials von Schadstoffen in Böden und Gewässern erfolgt eine Beschreibung der Regenerationsprozesse in Waldschadensgebieten und auf brachfallenden Landwi...

Naturräume sind nach Relief-, Boden,- Binnengewässer- und Klimaeigenschaften ausgewiesene Räume, denen eine spezifische, natürliche potentielle Vegetation entspricht. Durch jahrhundertelange Naturressourcen- und Landnutzung sind Naturräume zu Kulturlandschaften verändert worden.

Die Ökosysteme der alluvialen Wälder (Auwälder) in Mitteleuropa sind ein bedeutender Teil des europäischen Natur- und Kulturerbes. Sie bilden die natürlichen Vegetationseinheiten an den Flußläufen und ihren Überschwemmungsbereichen. Auwälder sind in der Vergangenheit großflächig durch menschliche Aktivitäten beeinflußt, verändert und zerstört worde...

Wesentliche Grundlage der industriellen Entwicklung seit Beginn des 19. Jahrhunderts ist im Raum Leipzig-Halle-Bitterfeld die Nutzung der Braunkohle als Energie- und Rohstoffbasis. Gekoppelt mit einer Reihe anderer Standortvorteile und dem technischen Fortschritt (u.a. Brikettierung der Kohle, Verfahren der Kohlechemie) kam es zu Beginn des 20. Jah...

The immature stages are the most vulnerable parts in the life cycle of a butterfly due to their low mobility (Porter 2002, Fartmann 2004). Hence, the larval ecology is often the key to the understanding of a species' distribution and abundance. We studied the larval habitat preferen-ces of two east Asian swallowtail butterflies (Papilio maackii and...
