Abstract In Germany, the decline of insect biomass was observed in nature conservation areas agricultural landscapes. One main causal factors discussed is use synthetic pesticides conventional agriculture. a Germany-wide field study, we collected flying insects using Malaise traps adjacent to land. We used multi-component chemical trace element analysis detect 92 common ethanol from sampled May and August 2020. total, residues 47 current were detected, samples on average contaminated with...
The worldwide rapid declines in insect and plant abundance diversity that have occurred the past decades gained public attention demand for political actions to counteract these are growing. Rapid large-scale biomonitoring can aid observing changes provide information decisions land management species protection. Malaise traps long been used sampling when insects captured traps, they carry traces of plants visited on body surface or as digested food material gut contents. Metabarcoding...
We present a DNA barcoding study on the insect order Orthoptera that was generated in collaboration between four projects three countries, viz. Barcoding Fauna Bavarica (Germany), German Barcode of Life, Austrian Life and Swiss Life. Our data set includes 748 COI sequences from 127 162 taxa (78.4%) recorded countries involved. Ninety-three these 122 species (76.2%, including all Ensifera) can be reliably identified using barcodes. The remaining 26 caeliferan (families Acrididae Tetrigidae)...
Abstract National and local governments need to step up efforts effectively implement the post‐2020 global biodiversity framework of Convention on Biological Diversity halt reverse worsening trends. Drawing recent advances in interdisciplinary science, we propose a for improved implementation by national subnational governments. First, identification actions promotion ownership across stakeholders recognize multiple values account remote responsibility. Second, cross‐sectorial mainstreaming...
Uniquely positioned at the intersection of sexual selection, nutritional ecology and life-history theory, nuptial gifts are widespread diverse. Despite extensive empirical study, we still have only a rudimentary understanding gift evolution because lack unified conceptual framework for considering these traits. In this opinion piece, tackle several issues that believe substantively hindered progress in area. Here, we: (i) present comprehensive definition classification scheme (including...
Sexual selection is a major force driving evolution and intertwined with ecological factors. Differential allocation of limited resources has central role in the cost reproduction. In this paper, I review costs benefits mating tettigoniids, focussing on nuptial gifts, their trade-off male calling songs, protandry how mate density influences choice. Tettigoniids have been widely used as model systems for studies benefits; they can provide useful general insights. The production exchange large...
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 surroundings, such as agrochemical inputs do not negatively affect protected habitats. Here, we compare effectiveness conservation measures under influence yield-optimized cultivation in Germany using vegetation analyses transects edge core areas at 21 sites. By analysing nitrogen...
Rapid divergence in external genital structures occurs nearly all animal groups that practice internal insemination; explaining this pattern is a major challenge evolutionary biology. The hypothesis species‐specific differences male genitalia evolved under sexual selection as courtship devices to influence cryptic female choice (CFC) has been slow be accepted. Doubts may stem from its radical departure previous ideas, observational difficulties because crucial events occur hidden within the...
Five years after a German study on insect biomass described multi-decade decline in nature protected habitats, the DINA (Diversity of Insects Nature Areas) project has investigated status insects 21 selected reserves across Germany 2020 and 2021. We used same methods protocols for trapping measuring flying as earlier study. Across two vegetation periods, we accumulated comprehensive data set 1621 points two-week emptying intervals to evaluate along gradients from arable land into through...
Abstract Currently, knowledge of arthropod diversity and distributions in terrestrial habitats is limited due to a lack taxonomists consistent monitoring, hindering insect conservation efforts. To address this, we conducted an extensive country‐wide study Germany using year‐long Malaise trap monitoring effort supported by citizen scientists. Our provides benchmark species occurrence 21 German nature‐protected areas. Metabarcoding methods revealed unexpectedly high small‐scale largely...
Mate choice is a common phenomenon in animals and several factors have been proposed as being involved the acceptance or rejection of partner. I investigated effect population density on mate-sampling behaviour female Xederra charactus (bushcrickets). In my study, bushcrickets adjusted tactic sequential mate sampling response to density, visiting series up five different males per night. Under low-density conditions, females visited fewer night were less likely reject copulation attempt than...
Abstract In T ettigoniidae ( O rthoptera: E nsifera), hearing organs are essential in mate detection. Male tettigoniids usually produce calling songs by tegminal stridulation, whereas females approach the males phonotactically. This unidirectional communication system is most common one among tettigoniids. several tettigoniid lineages, have evolved acoustic replies to male song which constitutes a bidirectional system. The genus P oecilimon ettigoniidae: haneropterinae) of special interest...
Chromosomes of the males five species Odontura, belonging to subgenera Odontura and Odonturella, were analyzed.Intensive evolution karyotype was recorded, both in terms changes numbers chromosomes (from 2n = 31 27) sex chromosome system X0 neo-XY neo-X1X2Y).Karyotype accompanied by tandem autosome fusions interspecific autosomal differentiation involving locations nucleolar organizer regions, NORs, which revealed silver impregnation confirmed FISH using an 18S rDNA probe.O.

Abstract Insect declines and biodiversity loss have attracted much attention in recent years, but lack of comprehensive data, conflicting interests among stakeholders insufficient policy guidance hinder progress preserving biodiversity. The project DINA (Diversity Insects Nature protected Areas) investigates insect communities 21 nature reserves Germany. All selected conservation sites border arable land, with agricultural practices assumed to influence populations. We taught citizen...
Abstract In recent years, the decline of insect biodiversity and imminent loss provided ecosystem functions services has received public attention raised demand for political action. The complex, multi-causal contributors to require a broad interdisciplinary cross-sectoral approach that addresses ecological social aspects find sustainable solutions. project Diversity Insects in Nature protected Areas (DINA) assesses communities 21 nature reserves Germany, considers interactions with plant...
Citizen Science (CS) is a research approach that has become popular in recent years and offers innovative potential for dialect ornithology. As the scepticism about CS data still widespread, we analysed development of 3-year project based on song Common Nightingale (Luscinia megarhynchos) to share best practices lessons learned. We focused scope, individual engagement, spatial distribution species misidentifications from recordings generated before (2018, 2019) during COVID-19 outbreak...
