Higher bee species richness in conservation areas compared with non‐conservation areas in south‐west Germany Open
Insects are declining in both species richness and abundance. Conservation areas are expected to mitigate this diversity loss, as they typically sustain higher species richness across various insect taxa compared with non‐conservation area…

Effects of land cover and protected areas on flying insect diversity Open
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…

Upscaling biodiversity monitoring: Metabarcoding estimates 31,846 insect species from Malaise traps across Germany Open
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 prohib…

Phenology of microhymenoptera and their potential threat by insect decline Open
Although microhymenoptera are highly abundant in all terrestrial ecosystems, they are overlooked in most of insect monitoring studies due to their small-size and demanding identification linked with lack of taxonomic experts. Until now, it…
No recovery in the biomass of flying insects over the last decade in German nature protected areas Open
Five years after a German study on insect biomass described a multi‐decade decline in nature protected habitats, the DINA (Diversity of Insects in Nature protected Areas) project has investigated the status of insects in 21 selected nature…
Recommendations for effective insect conservation in nature protected areas based on a transdisciplinary project in Germany Open
The decline of insect abundance and richness has been documented for decades and has received increased attention in recent years. In 2017, a study by Hallmann and colleagues on insect biomasses in German nature protected areas received a …
Insect biomass of protected habitats under the impact of arable farming in Germany Open
Five years after the well-known study on insect biomass decline in nature protected habitats in Germany over three decades, the project DINA (Diversity of Insects in Nature protected Areas) has investigated the status of insects in 21 sele…

Upscaling biodiversity monitoring: Metabarcoding estimates 31,846 insect species from Malaise traps across Germany Open
Mitigating ongoing losses of insects and their key functions (e.g., pollination) requires accurately tracking large-scale and long-term community changes. However, doing so has been notoriously hindered by uniquely high insect species dive…
Negative spill-over effects of agricultural practices on plant species conservation in nature reserves Open
Nature reserves are one of the most important instruments for biodiversity protection and to limit regional species extinctions. However, these functions can only be fulfilled if environmental influences from the surroundings, such as agro…
Spatial, temporal and taxonomic patterns of insect extinction in Germany Open
Red lists represent an important instrument for evaluating the decline of species in space and time, for improving decisionmaking and for guiding conservation planning. However, globally, only a fraction of species has been categorized acc…
Improving insect conservation management through insect monitoring and stakeholder involvement Open
In recent years, the decline of insect biodiversity and the imminent loss of provided ecosystem functions and services has received public attention and raised the demand for political action. The complex, multi-causal contributors to inse…
Development of an insect sample fractionizer for biodiversity research Open
We describe a new mechanical tool for dividing mixed insects and other invertebrate samples into subsamples. The device enables the division to equal parts by means of a movable hemispherical bowl and a separating disc. Due to the complete…
Repeated subsamples during <span>DNA</span> extraction reveal increased diversity estimates in <span>DNA</span> metabarcoding of Malaise traps Open
With increased application of DNA metabarcoding in biodiversity assessment, various laboratory protocols have been optimized, and their further evaluation is subject of current research. Homogenization of bulk samples and subsequent DNA ex…
The potential of metabarcoding plant components of Malaise trap samples to enhance knowledge of plant-insect interactions Open
The worldwide rapid declines in insect and plant abundance and diversity that have occurred in the past decades have gained public attention and demand for political actions to counteract these declines are growing. Rapid large-scale biomo…
A universal insect trait tool (ITT, v1.0) for statistical analysis and evaluation of biodiversity research data Open
We present a unique data set of trait information for 586 insect families in Central Europe, covering the largest known part of described species (over 34,000 species). Life history information and major functional traits were evaluated wi…
Recommendations for tissue homogenisation and extraction in DNA metabarcoding of Malaise trap samples Open
With increased application of DNA metabarcoding in fast and high-resolution biodiversity assessment, various laboratory protocols have been optimised in recent years and their further evaluation is subject of current research. Homogenisati…
Metabarcoding malaise trap plant components enables monitoring the diversity of plant-insect interactions Open
The declines observed in insect abundance and diversity in the past decades has also been observed in plants, and these events are most certainly correlated. Rapid largescale biomonitoring of both plants and insects can help monitor these …

Pooling size sorted Malaise trap fractions to maximize taxon recovery with metabarcoding Open
Background Small and rare specimens can remain undetected when metabarcoding is applied on bulk samples with a high specimen size heterogeneity. This is especially critical for Malaise trap samples, where most of the biodiversity is contri…
Diversity of Insects in Nature protected Areas (DINA): an interdisciplinary German research project Open
Insect declines and biodiversity loss have attracted much attention in recent years, but lack of comprehensive data, conflicting interests among stakeholders and insufficient policy guidance hinder progress in preserving biodiversity. The …
Insect biomass decline scaled to species diversity: General patterns derived from a hoverfly community Open
Significance Various sources have reported insect decline in total biomass, numbers, and species diversity. With German data on a species-rich hoverfly community over 25 y and a theoretical model, we show how these decline rates are interr…
Data and code from: Insect biomass decline scaled to species diversity: General patterns derived from a hoverfly community Open
To study changes in flying insect communities, and hoverflies in particular, malaise trap samples from a German site were compared between two years (Hallmann et al. 2020). The data files deposited here contain data obtained from six malai…
