“…Notably, the highest number of individuals (many ubiquitous species such as Philonthus cognatus, Philonthus carbonarius Gravenhorst, 1802, and Xantholinus longiventris Heer, 1839) was found on drained fens characterised by dry, more degraded habitats. Finally, vegetation height, determining a suitable microclimate, also had a crucial impact on staphylinid assemblages in agreement with earlier studies (Dennis et al, 2004;Eyre & Luff, 2005;Hoffmann et al, 2016). While the investigations of the river Peene wetlands show positive effects of restoration despite creating discrete communities, other studies showed more mixed results with regard to the success of rewetting in restoring macroinvertebrate assemblages (Verberk et al, 2006;Beadle et al, 2015;Punttila et al, 2016).…”

“…At least partly, the high diversity of staphylinids is probably explained by the high diversity of micro-habitats (dense reed vegetation, successional stages, open areas) within rewetted stands, due to grazing and grubbing by red deer and wild boar (Boh ac, 1999;Irmler & G€ urlich, 2007;Zerbe et al, 2013). Also, the relatively high water levels as well as the high vegetation heights reached on rewetted stands probably had positive effects on staphylinids (Boh ac & Fuchs, 1994b;Hoffmann et al, 2016).…”

“…More than 60% of European and around 99% of German fens and bogs have been destroyed already (Joosten, 1997). Remaining peatlands are thus important ecosystems which harbour a wealth of endangered animal and plant species and fen-specific species assemblages Hoffmann et al, 2016). Consequently, the protection of pristine fens as well as the restoration of already degraded fens to restore ecosystem services are conservation issues of international importance (Van Andel & Aronson, 2006;M€ alson et al, 2010).…”

“…Former studies in the Peene valley have compared the effects of different management regimes on indicator groups including birds, butterflies, grasshoppers, carabid, and rove beetles (G€ orn & Fischer, 2011;G€ orn et al, 2014Hoffmann et al, 2016). Effects of fen restoration have been investigated only for carabid beetles and vascular plants .…”

Peatlands have undergone dramatic changes through anthropogenic activities in the last centuries, causing a substantial loss of fen‐specific biodiversity. Therefore, restoration of already degraded stands is an important conservation issue. The effectiveness of fen restoration was evaluated through rewetting in the valley of the river Peene, NE Germany, by comparing three fen types: drained fens, rewetted fens, and near‐natural fens. Rove beetles (Coleoptera: Staphylinidae) were used as indicators, comprising an ecologically important yet understudied insect group. 5,398 individuals from 121 staphylinid species were recorded by 30 pitfall traps per fen type, which were biweekly emptied between April and October 2012, and related to environmental parameters. Rove beetle assemblages differed markedly between fen types. Community structure was affected by peat degradation, the extent of organic matter, water level, and vegetation height. Fen rewetting favoured the establishment of a distinct, species‐rich beetle community within 15 years only, caused by an increase in hygrophilous wetland species partially replacing generalists. Nevertheless, this time span was not sufficient to restore communities characteristic for near‐natural fens, which harboured several particularly sensitive species that were not found on rewetted fens. Rewetting provided suitable habitats for a substantial number of stenotopic and threatened staphylinid beetles. Thus, the protection of pristine habitats along with restoration measures are both important strategies in peatland conservation.

Biodiversity in agricultural landscapes: different non-crop habitats increase diversity of ground-dwelling beetles (Coleoptera) but support different communities

Agricultural intensification poses a major threat to the conservation of biodiversity and associated ecosystem services. Since non-crop habitats are regarded as important refuges for farmland biodiversity, various greening measures have been proposed to halt biodiversity loss. However, the effectiveness of these measures for biodiversity conservation is still under debate. Therefore, we here compared ground-dwelling beetle (Coleoptera) assemblages of different non-crop habitats (field margins, set-aside fields sown with wildflowers, and permanent grassland fallows) and wheat fields within an intensively used agricultural landscape in western Germany. Taxonomic diversity of Carabidae, Staphylinidae and other coleopteran families and their conservation value were higher in all non-crop habitats than on wheat fields. Surprisingly, though, different types of non-crop habitats did not differ in species richness or the number of threatened species. Thus, field margins and sown wildflower fields were as effective in promoting beetle diversity as grassland fallows. However, different non-crop habitats supported different species assemblages, and several species, in particular especially large ones, were restricted to grassland fallows. These results suggest that different greening measures are effective in promoting the biodiversity of beetles, and that permanent grassland fallows are essential for nature conservation. The fact that habitat types harbored different assemblages stresses the need to combine a variety of greening measures to yield the highest benefit for biodiversity.

The cultivation of peat mosses (‘Sphagnum farming’) is a new wet and climate-friendly agricultural use of degraded bog sites. However, it is largely unknown to what extent these surrogate habitats are used by bog fauna. This study investigated the potential of Sphagnum cultivation sites as surrogate habitats for beetles and evaluated the relationship between the vegetation structure and the occurrence of beetle species. In 2017 and 2018, comparative surveys were carried out at different sub-areas of two Sphagnum cultivation sites and one near-natural bog. Beetles living in and on the upper Sphagnum layer were studied by manually extracting quadrat samples. Vegetation surveys were conducted in the same quadrats to analyze the occurrence of beetle species based on vegetation parameters. We collected 926 individuals of beetles belonging to 89 species out of 17 families. At the different sections of the cultivation sites, 8–16 bog-typical beetle species were found, while at the sub-areas of the near-natural bog, there were 15 and 19 bog-typical species, respectively. The statistical analyses showed that vegetation structure influenced the numbers of beetle species and individuals at both the cultivation and near-natural sites. Implications for insect conservation A dense and high Sphagnum carpet is a fundamental habitat structure for the beetle fauna of cultivation sites, while vascular plants initially help to create habitat structures on bare peat. Conversely, if the vascular plants overgrow and shade the Sphagnum, this can have a negative effect on bog-typical beetle species, as shown at the near-natural site.
