The European biodiversity and forest strategies rely on sustainable management (SFM) to conserve biodiversity. However, current sustainability assessments hardly account for direct indicators. We focused multi-taxon to: i) gather map the existing information; ii) identify knowledge research gaps; iii) discuss its potential. established a network fit data species, standing trees, lying deadwood sampling unit description from 34 local datasets across 3591 units. A total of 8724 species were...
Abstract Lentic freshwater organisms are influenced by a multitude of factors, including geomorphology, hydrology, anthropogenic impacts and climate change. Organisms that depend on patchy resources such as water beetles may also be sensitive to habitat degradation, like pollution, eutrophication, level or management alteration. To assess composition ecological trends in the beetle communities Central Europe, we sampled (Dytiscidae, Haliplidae, Noteridae) 33 bodies Southern Germany from 1991...
The high diversity of insects has limited the volume long‐term community data with a taxonomic resolution and considerable geographic replications, especially in forests. Therefore, trends causes changes are poorly understood. Here we analyse species richness, abundance biomass nocturnal macro moths three quantitative sets collected over four decades forests southern Germany. Two local sets, one from coppiced oak included 125K 48K specimens 559 532 species, respectively. A third regional...
Abstract Aim European temperate forests have lost dead wood and the associated biodiversity owing to intensive management over centuries. Nowadays, some of these are being restored by enrichment with wood, but mostly only at stand scales. Here, we investigated effects a seminal dead‐wood strategy on saproxylic organisms landscape scale. Location Temperate beech forest in southern Germany. Methods In before–after control–impact design, compared assemblages gamma diversities strictly protected...
Abstract Insecticides used to combat outbreaks of forest defoliators can adversely affect non‐target arthropods. Forestry insecticides typically suppress Lepidoptera larvae which are the cornerstone canopy community deciduous oak forests. The abrupt removal this dominant component food web could have far‐reaching implications for ecosystems, yet it is rarely investigated in practice owing several methodological shortcomings. taxonomic impediment and biased nature arthropod sampling...
Outbreaks of the spongy moth Lymantria dispar can have devastating impacts on forest resources and ecosystems. Lepidoptera-specific insecticides, such as Bacillus thuringiensis var. kurstaki (BTK) tebufenozide, are often deployed to prevent heavy defoliation canopy. While it has been suggested that using BTK poses less risk non-target Lepidoptera than leaving an outbreak untreated, in situ testing this assumption impeded by methodological challenges. The trade-offs between insecticide use...
Abstract Forest ecosystems are facing increasing challenges like natural disturbances. Despite positive disturbance impacts on the diversity of several taxonomic groups, there still concerns, whether drastic canopy opening can lead to a turnover from forest open habitat species. We sampled arthropods along gradient in Norway spruce ( Picea abies )‐dominated protected areas across Central Europe using Malaise traps and metabarcoding. To analyse changes arthropod communities terms affinities...
Previous macroecological studies have suggested that larger and darker insects are favored in cold environments the importance of body size color for absorption solar radiation is not limited to diurnal insects. However, whether these effects hold true local communities consistent across taxonomic groups sampling years remains unexplored. This study examined variations lightness two major families nocturnal moths, Geometridae Noctuidae, along an elevational gradient 700 m Southern Germany....
Natural disturbances are increasing around the globe, also impacting protected areas. Although previous studies have indicated that natural result in mainly positive effects on biodiversity, these analyses mostly focused a few well established taxonomic groups, and thus uncertainty remains regarding comprehensive impact of biodiversity. Using Malaise traps meta-barcoding, we studied broad range arthropod taxa, including dark cryptic along gradient bark beetle disturbance severities five...
Abstract Aim Despite increasing interest in β‐diversity, that is the spatial and temporal turnover of species, mechanisms underlying species at different scales are not fully understood, although they likely differ among functional groups. We investigated relative importance dispersal limitations environmental filtering caused by vegetation for local, multi‐taxa forest communities differing their ability, trophic position body size. Location Temperate forests five regions across Germany....
from about 850 different macro Lepidoptera species. The two most dominant families were the Geometridae and Noctuidae with 350000 specimens of 343 species 240000 345 species, respectively. While overall diversity remained constant before 1990s 2000s, it decreased significantly after year 2000. same pattern occurred subset while showed an inferior decline 2000, where was lower than but not 1990. This phenomenon may be due to biology families. We conclude that conservation measures should...
Changes and development are fundamental principles in biocenoses can affect a multitude of ecological processes. In insect communities phenological density changes, changes species richness community composition, as well interactions between those the most important macro However, climate change other factors like habitat degradation loss alter these processes leading to shifts general biodiversity declines.
