Many insect species have specific habitat preferences, which often even differ for larval instars and imagines within a species. In these cases, the two habitats have to be in close proximity to each other. The habitats in question, e. g. dung and dead wood, are often in decline due to land-use changes and anthropogenic impacts. The processes leadi...

• Among the many concerns for biodiversity in the Anthropocene, recent reports of flying insect loss are particularly alarming, given their importance as pollinators, pest control agents, and as a food source. Few insect monitoring programmes cover the large spatial scales required to provide more generalizable estimates of insect responses to glob...

Ground beetles (Coleoptera: Carabidae) on a recently established wood-pasture: a case study from southwest Germany-Historical experience shows that wood-pastures provide high habitat diversity and thus also a high degree of species diversity, and as such they have been under discussion for some years as a conservation measure. However, the developm...

We report faunistic data from the Black Forest National Park for 39 nationally rare and extremely rare beetle species.

Widespread insect losses are a critical global problem. Mitigating this problem requires identifying the principal drivers across different taxa and determining which insects are covered by protected areas. However, doing so is hindered by missing information on most species owing to extremely high insect diversity and difficulties in morphological...

Mitigating ongoing losses of insects and their key functions (e.g. pollination) requires tracking large‐scale and long‐term community changes. However, doing so has been hindered by the high diversity of insect species that requires prohibitively high investments of time, funding and taxonomic expertise when addressed with conventional tools. Here,...

Many insect species are facing existential crises, primarily due to diverse human-induced activities. Most insect assessments, however, are based on short-term data or some iconic species. Here, in close collaboration with taxonomic experts from natural history societies, we compiled the best available occurrence data for ground beetles in Germany,...

Forest ecosystems are facing increasing challenges like natural disturbances. Despite positive disturbance impacts on the diversity of several taxonomic groups, there are still concerns, whether the drastic canopy opening can lead to a turnover from forest to open habitat species. We sampled arthropods along a disturbance gradient in Norway spruce...

Rothirsche besitzen durch ihr Nahrungsverhalten einen großen Einfluss auf die Entwicklung von Waldökosystemen, so dass genaue Informationen zu ihrer Nahrungszusammensetzung eine wichtige Grundlage für das Wildtiermanagement bilden.

1. The diversity in meadows is affected by numerous aspects, such as the amount and type of fertilisation and the timing and frequency of cutting. The effects of mowing on the diversity of plants and insects have been studied in detail. However, the effect of mulching (vegetation is cut, shredded, and left in place, instead of being removed) on ins...

We report on a structural complexity enhancement (SCE) experiment that was designed to test ecological restoration measures in the Black Forest National Park, Germany. The main goal was to understand as to whether the creation of standing and downed deadwood within previously managed, single-layered Norway spruce (Picea abies L.) forests accelerate...

We report records of rove beetles sampled in horse dung (Konik) between May and September in a German national park.

National parks play an important role in protecting global biodiversity. The development and implementation of a biodiversity assessment program that enables the analysis and evaluation of biodiversity development under protection is a task of the national park administration. This paper presents the sampling design and assessment methods used for...

Recent studies have emphasized forests as crucial habitat for wild bees. In Europe, most forests are managed following the principles of close-to-nature silviculture, which combine timber production and nature conservation. However , open late and early successional stages within these forests are largely missing, which could be important for wild...

Recent reports on insect decline have highlighted the need for long‐term data on insect communities towards identifying their trends and drivers. With the launch of many new insect monitoring schemes to investigate insect communities over large spatial and temporal scales, Malaise traps have become one of the most important tools due to the broad s...

Pig pastures are among the rarest forms of pasture in Europe today. For a long period of time in history this was not the case. In central Europe, domesticated pigs have been held on pastures since the Neolithic period, and this remained a widespread practice up until the beginning of the 20th century. There has been little research into the ecolog...

Traditional forms of agriculture have created and preserved heterogeneous landscapes characterized by semi-natural meadows and pastures, which have high conversation value for biodiversity. Landscapes in Central and Eastern European countries with traditional agriculture are a stronghold for pollinators, butterflies and amphibians, which have decli...

Natural disturbances are increasing around the globe, also impacting protected areas. Although previous studies have indicated that natural disturbances result in mainly positive effects on biodiversity, these analyses mostly focused on a few well established taxonomic groups, and thus uncertainty remains regarding the comprehensive impact of natur...

Totholz ist eine wichtige Ressource in Waldökosystemen. Das Wissen um die Bedeutung des Totholzes als Lebensraum für obligate Totholzbewohner hat in den letzten 30 Jahren erheblich zugenommen. Dadurch verstehen wir immer besser, wie wichtig Totholz in unterschiedlichen Zersetzungsstadien für die Erhaltung der Biodiversität ist. Es ist mittlerweile...

Dung beetles are a functionally important group of species, and the effects of large wild herbivores on these species are not well understood. Management of wild herbivores could, therefore, have considerable consequences for dung beetle assemblages and the ecosystem services they provide. Here, we analysed how species richness, biomass, abundance,...

• Central European forests experience a substantial loss of open-forest organisms due to forest management and increasing nitrogen deposition. However, management strategies, removing different levels of nitrogen, have been rarely evaluated simultaneously. • We tested the additive effects of coppicing and topsoil removal on communities of dung-inha...

The carabids of the tribe Platynini from the southern Levant (Egypt: Sinai Peninsula, Israel, Jordan) and adjacent regions of Egypt, Lebanon, Syria, Iraq, and Saudi Arabia are reviewed in terms of species taxonomy, ecological, distributional traits, and conservation biology. In addition to a classical dichotomous identification key to the 14 specie...

The extinction of species is a non‐random process, and understanding why some species are more likely to go extinct than others is critical for conservation efforts. Functional trait‐based approaches offer a promising tool to achieve this goal. In forests, deadwood‐dependent (saproxylic) beetles comprise a major part of threatened species, but anal...

Structural complexity enhancement (SCE) is a forest restoration approach aiming to maintain or increase biodiversity in managed, secondary forests. Whether the diversity of wild bees also benefits from such restoration measures in temperate forests is not well studied. We conducted a restoration experiment in secondary spruce forests on twelve 50 ×...

Blockhalden sind ein seltener und zugleich extremer Lebensraum. Im Hunsrück und anderen Gebieten sind diese letzten Primärlebensräume nur unzureichend untersucht, obwohl sie hochgradig spezialisierte Arten beherbergen können. Wir haben vier Blockhalden im Rahmen einer ersten Erfassung mit Bodenfallen untersucht und dadurch Nachweise von seltenen Sp...

In den mitteleuropäischen Mittelgebirgen zählt die Beweidung mit Rindern zu den seit langer Zeit etablierten Nutzungsformen in der Kulturlandschaft. Die gegenwärtige Diskussion um Maßnahmen gegen den Rückgang von Insektenarten und der Insekten-Biomasse berücksichtigt die positiven Wirkungen der Beweidung nur unzureichend. Mit Rindern beweidete Fläc...

Im Nationalpark sind hinsichtlich des Naturschutzes zwei große Aufgaben zu erfüllen: Einerseits soll im Prozessschutz Natur frei von menschlichen Einflüssen sein dürfen. Andererseits gibt es im Nordschwarzwald seltene und geschützte Arten und nur hier existierende Biotope, die es zu bewahren gilt. Das Modul Arten- und Biotopschutz beschäftigt sich...

Obituary on Dr. Martin Baehr (10.3.1943 – 17.4.2019)

Leistus montanus is a stenotopic ground beetle that predominantly inhabits exposed block fields in mountain ranges. Its regional distribution in Germany is still uncertain, and quantitative descriptions of its habitat are lacking. We studied block fields in two low-mountain ranges, the Black Forest and the Hunsrück, by means of hand collecting or p...

Ancient woodlands differ from recent woodlands by numerous abiotic and biotic factors, including soil properties. Several animal species are more abundant in ancient than in recent woodlands, but this has been only rarely tested for saprophagous taxa and not at all for dung beetles, which are common in temperate woodlands. Beside habitat continuity...

In the face of the decline of many insects, there is an increasing demand for contemporary, fast and cost-effective approaches to monitor the development of populations and species. Numerous scientists favor molecular methods, especially those involving barcoding of the CO1 gene, as an alternative to classical, morphology-based species identificati...

1. Ecosystem processes depend on the biomass of the involved organisms, but their functional diversity may play an additional role. In particular, the exclusion of key functional groups through habitat disturbance may lead to the breakdown of ecosystem functions. Dung removal is an important process contributing to nutrient cycling and thus product...

In woodlands, land use legacy, but also present habitat management can influence biodiversity and ecosystem functions in various ways. However, little is known about how former and current land use interact in woodlands with different habitat continuity and tree age. The aim of this study was to investigate the impact of both habitat continuity and...

The island of Asinara, located in the northwest of Sardinia, is characterized by a large number of feral grazing mammals belonging to four herbivorous species (horse, donkey, mouflon, and goat) and an omnivorous one (wild boar). Hand-collections of scarabs in 2014 and the examination of unpublished records revealed the presence of five species new...

The Mediterranean Red List assessment is a review of the conservation status at regional level of approximately 6,000 species of animals and plants. This report summarizes the results for a key group of Mediterranean biodiversity: saproxylic beetles.

The spiny scree wolf spider Acantholycosa norvegica sudetica (L. Koch) (Araneae: Lycosidae) in the northern Black Forest Screes belong to the last pristine habitats in Central Europe. Several of those are located in the new National Park in the northern Black Forest, but were still not explored scientifically. Seven screes in the Black Forest Nati...

The paper provides an overview of the current distribution in Germany.

Aim In several ecosystems, the diversity of functional species traits has been shown to have a stronger effect on ecosystem functioning than taxonomic diversity alone. However, few studies have explored this idea at a large geographical scale. In a multisite experiment, we unravelled the relationship between ecosystem function and functional comple...

The European bilberry, Vaccinium myrtillus L. (Ericaceae), is an important food resource for many mammals, insects and birds in forests, including the threatened capercaillie (Tetrao urogallus). For capercaillie, a sufficient amount of bilberry fruits is crucial to store enough body fat for the winter period. Studies have shown that V. myrtillus re...

Man-made small game meadows in forest-dominated landscapes may become important refuge habitats for invertebrates under the currently observed severe decline of grasslands characterized by low land-use intensity. We studied the ground beetle community of 24 small meadows that are used as grazing grounds for red deer (Cervus elaphus) in the sub-mont...

By manipulating faeces during feeding and breeding, dung beetles (Coleoptera: Scarabaeidae) fulfil important ecosystem functions in terrestrial ecosystems throughout the world. In a pan-European multi-site experiment (MSE), we estimated the ecosystem functions of dung removal and secondary seed dispersal by differing combinations of dung beetle fun...
