Neue Funde seltener Zikadenarten auf den Kalkmagerrasen des Diemeltals (Ostwestfalen/Nordhessen): (Hemiptera, Auchenorrhyncha)

Im Jahr 2013 wurden auf zehn Kalkmagerrasen des Mittleren und Un-teren Diemeltals (Ostwestfalen/Nordhessen) systematische Zikadenerfassungen durchge-führt. Insgesamt konnten 82 Arten nachgewiesen werden. Darunter waren 24 Arten, die erstmalig für das Untersuchungsgebiet erfasst werden konnten. Unter Berücksichtigung der Studie von Poniatowski & Hertenstein (2013) umfasst die Checkliste der Kalkmagerrasen des Mittleren und Unteren Diemeltals nun 108 Zikadenarten. Davon sind 30 Arten in der Roten Liste der gefährdeten Zikadenarten Deutschlands einer Gefährdungskategorie zuge-ordnet. 45 Arten wurden als Halbtrockenrasen-Spezialisten eingestuft. Zu den bemerkens-werten Erstnachweisen gehören Arocephalus languidus, Asiraca clavicornis, Eurysella brunnea, Hesium domino, Mocydiopsis attenuata, Ribautodelphax collina und Wagneriala sinuata. Darüber hinaus konnten für die stark gefährdeten Arten Doratura horvathi, Eupteryx origani, Hephathus nanus und Tettigometra impressopunctata weitere Fundstellen ermittelt werden.New records of rare Auchenorrhyncha species for the calcareous grasslands in the Diemel Valley (Ostwestfalen/Nordhessen) (Hemiptera: Auchenorrhyncha). – In 2013 we sampled Auchenorrhyncha in ten calcareous grassland sites in the Middle and Lower Diemel Valley (Central Germany). In total, we found 82 species. Among these, 24 species represent new records for the study area. Taking into account the study of Poniatowski & Hertenstein (2013), a total number of 108 species is now documented for the Diemel Valley. 30 species are on the Red List of the Auchenorrhyncha of Germany. A total of 45 species were classi-fied as specialists of semi-dry grasslands. Remarkable new species are Arocephalus languidus, Asiraca clavicornis, Eurysella brunnea, Hesium domino, Mocydiopsis attenuata, Ribautodelphax collina and Wagneriala sinuata. Additionally, we found new sites for the endangered species Doratura horvathi, Eupteryx origani, Hephathus nanus and Tettigometra impressopunctata

Die Zikadenfauna der Kalkmagerrasen des Mittleren und Unteren Diemeltals (Ostwestfalen/Nordhessen): (Hemiptera, Auchenorrhyncha)

In den Jahren 2010 und 2011 wurden auf den Kalkmagerra- sen des Mittleren und Unteren Diemeltals (Ostwestfalen/Nordhessen) Zikaden gesammelt. Insgesamt konnten 84 Arten nachgewiesen werden. 44 Arten beschränken sich im Untersuchungsgebiet auf Kalkmagerrasen und können daher zumindest auf regionaler Ebene als Halbtrockenrasen-Spezialisten gelten. Unter den Spezialisten sind 15 Arten auf der aktuellen Roten Liste der Zikaden Deutschlands als gefährdet oder stark gefährdet vertreten. Bemerkenswert ist das Vorkommen von Batracomorphus irroratus, Doratura horvathi, Eupteryx origani, Euscelis venosus, Goniagnathus brevis, Hephathus nanus und Tettigometra impressopunctata. Die meisten dieser Arten sind xerophil, gefährdet oder sogar stark gefährdet und erreichen im Diemeltal den Nordrand ihres Areals.The Auchenorrhyncha fauna of calcareous grassland habitats of the Middle and Lower Diemel Valley (central Germany). – In 2010 and 2011 we sampled Auchenorrhyncha in several calcareous grassland sites in the Middle and Lower Diemel Valley (central Germany). In total, we found 84 species. 44 species were restricted to calcareous grasslands in the study area and are therefore regionally classified as habitat specialists. Among these, 15 species are listed as vulnerable or endangered on the Red List of Auchenorrhyncha species of Germany. Remarkable species were Batracomorphus irroratus, Doratura horvathi, Eupteryx origani, Euscelis venosus, Goniagnathus brevis, Hephathus nanus and Tettigometra impressopunctata. Most of these species are xerophilous, endangered and reach their northern or northwestern range limit in the Diemel Valley

Die Zikadenfauna isolierter Schieferkuppen der Medebacher Bucht (Südwestfalen/Nordhessen): (Hemiptera, Auchenorrhyncha)

Im Jahr 2014 wurden auf 30 Schieferkuppen der Medebacher Bucht (Südwestfalen/Nordhessen) systematische Zikadenerfassungen durchgeführt. Insgesamt konnten 102 Arten nachgewiesen werden. Davon sind 31 Arten in der Roten Liste der gefährdeten Zikadenarten Deutschlands einer Gefährdungskategorie zugeordnet. Acht Arten wurden als Trockenrasen-Spezialisten und 60 Arten als typische Grünlandbewohner eingestuft. Besonders hervorzuheben sind die Nachweise von Delphacinus mesomelas, Jassidaeus lugubris, Stictocoris picturatus und Xanthodelphax flaveola. Sie sind alle Indikatoren historisch alter, extensiv genutzter Weidelandschaften. Jassidaeus lugubris und Xanthodelphax flaveola konnten erstmalig für Nordrhein-Westfalen nachgewiesen werden.The Auchenorrhyncha fauna (Hemiptera) of isolated acidic hilltops of the “Medebacher Bucht” (central Germany). – In 2014 we sampled Auchenorrhyncha on 30 acidic grassland sites in the “Medebacher Bucht” (central Germany). In total, we found 102 species. Among these, 31 species are on the Red List of the Auchenorrhyncha of Germany. A total of eight species were classified as xerothermophilous habitat specialists and 60 species as typical grassland species in Germany. Particularly noteworthy are the records of Delphacinus mesomelas, Jassidaeus lugubris, Stictocoris picturatus und Xanthodelphax flaveola. All of them are indicators for ancient traditionally grazed pastures. The records of Jassidaeus lugubris and Xanthodelphax flaveola were new for North North-Rhine-Westphalia

Relative impacts of land-use and climate change on grasshopper range shifts have changed over time

CITATION: Poniatowski, D. et al. 2020. Relative impacts of land-use and climate change on grasshopper range shifts have changed over time. Global Ecology and Biogeography 29(12): 2190– 2202. doi:10.1111/geb.13188The original publication is available at https://onlinelibrary.wiley.com/journal/14668238Aim: Stopping the decline of biodiversity is one of today’s greatest challenges. To help address this, we require studies that disentangle the effects of the most important drivers behind species range losses and shifts. In this large-scale study, we aim to evaluate the relative impacts of changes in land use and climate on distributional changes in grasshoppers. Location: Central Europe. Time period: Historical (pre-1990 vs. 1990–1999); recent (1990–1999 vs. 2000–2017). Major taxa studied: Orthoptera (hereafter referred to as grasshoppers). Methods: We used an advanced modelling approach within the framework of spatial point pattern analysis (SPPA) to calculate distributional changes of 58 grasshopper species based on > 100,000 aggregated observational records. Historical and recent range shifts were compared among four functional groups and analysed against: (a) the species temperature index (STI); and (b) the species farmland index (SFI). Results: During the earlier historical period, most species suffered from large range losses, with habitat specialists declining more than generalists with equal mobility. Range retractions were related to species with high SFI values; that is, species associated with farmland having a high natural value. In contrast, during the recent period the distribution of less mobile species generally remained stable, whereas highly mobile species even expanded their ranges, irrespective of their habitat specificity. Additionally, range expansions occurred mostly among thermophilic species; that is, those with high STI values. Main conclusions: This is the first large-scale study world-wide that quantifies both historical and recent range shifts of numerous grasshopper species. Our results suggest that historical range losses were mainly caused by severe loss of semi-natural habitats pre-1990. Recently, global warming has led to range expansions of several grasshopper species. The challenge now is to ensure the persistence of species that might not be able to evade future climate change owing to the increasing lack of suitable refuge habitats in intensive agricultural landscapes.https://onlinelibrary.wiley.com/doi/full/10.1111/geb.1318

Auchenorrhyncha and Psylloidea collected during the 25th Central European Auchenorrhyncha meeting, Arnhem, The Netherlands (Hemiptera: Auchenorrhyncha and Psylloidea)

Die 25. Mitteleuropäische Zikadentagung fand vom 14.-17. September 2018 in Arnheim in den Niederlanden statt. Da es die erste Tagung in den Niederlanden war, wurden Sammelexkursionen in fünf typische niederländische Landschaften unternommen. Drei der Exkursionsziele befanden sich in neu geschaffenen Schutzgebieten, die sich auf ehemals landwirtschaftlich genutzten Flächen befinden. Die beiden weiteren Exkursionsziele waren alte, geschützte Heideflächen. Insgesamt konnten 117 Zikadenarten und 6 Psylloidea-Arten nachgewiesen werden. Drei Arten waren neu für die Niederlande: Macrosteles spinosus (in dieser Publikation vorgestellt), Kybos abstrusus (monophag an Populus nigra) und Macrosteles sardus (an Epilobium hirsutum). Für einige seltene Arten konnten neue Fundpunkte ermittelt werden: Kelisia monoceros, Aphrophora major, Stroggylocephalus agrestis, Edwardsiana diversa, E. tersa, Fruticidia bisignata, Ophiola russeola und Psammotettix pallidinervis. Durch die drei Neufunde erhöht sich die Anzahl der bislang in den Niederlanden nachgewiesenen Zikadenarten auf 421. Diese Arbeit zeigt zudem, dass selbst in erst seit kurzem bestehenden Schutzgebieten seltene und interessante Arten nachgewiesen werden können. The 25th Central European Auchenorrhyncha meeting took place in Arnhem, The Netherlands on 14-17 September 2018. It was the first time the meeting was held in The Netherlands, and for this reason, excursions were undertaken to five typical Dutch landscapes. Three of the excursions involved newly created nature reserves, located on former agricultural land. The other two were old, protected heathlands. In total, 115 Auchenorrhyncha species, and 6 Psylloidea species were collected. Three species were new for the Netherlands: Macrosteles spinosus (presented in this paper), Kybos abstrusus (monophagous on Populus nigra) and Macrosteles sardus (Epilobium hirsutum). For a number of rare species new occurrences were reported: Kelisia monoceros, Aphrophora major, Stroggylocephalus agrestis, Edwardsiana diversa, E. tersa, Fruticidia bisignata, Ophiola russeola and Psammotettix pallidinervis. Our results show that also in young, newly created nature reserves interesting species can be found.&nbsp

The Orthoptera communities of sub-Mediterranean dry grasslands (Aphyllanthion alliance) in the western Spanish Pyrenees

14 páginas, 2 figuras, 1 tabla.[EN]: Sub-Mediterranean dry grasslands (Aphyllanthion alliance) are habitats with high biodiversity that have recently become threatened by abandonment of traditional management activities. Orthoptera communities are highly influenced by the spatial structure and thus indicate the quality of a habitat. The communities can be classified by the occurrence of characteristic Orthoptera species (regional "character species" and/or "differential species" according to PONIATOWSKI & FARTMANN 2008). We studied the composition of these communities in 21 plots along an elevation gradient from 750 to 1150 m a.s.l. in the Aísa Valley, western Aragonese Pyrenees (Spain). We defined three Orthoptera communities: (i) a community of herb- and grass-rich grasslands (type 1) with the character species Tessellana tessellata, (ii) a community of shrub-rich grasslands (type 2) with the character species Thyreonotus corsicus and Chorthippus binotatus binotatus and the differential species Stenobothrus lineatus and (iii) a community of rocky grasslands (type 3) with the character species Chorthippus b. binotatus and the differential species Oedipoda coerulea. Moreover, we analysed the ecological traits of the character and differential species: Tessellana tessellata prefers homogenous, high and dense vegetation, while the occurrence of Thyreonotus corsicus and Stenobothrus lineatus depends on heterogeneous, vertically wellstructured habitats with herbs and bushes. In contrast, optimal habitats of Oedipoda coerulea are characterized by a high proportion of bare ground, and the occurrence of Chorthippus b. binotatus is restricted to sites with a high dwarfshrub cover.[AL]: Submediterrane Trockenrasen (Verband Aphyllanthion) sind Lebensräume mit einer hohen Biodiversität, die heutzutage durch die Aufgabe traditioneller Landnutzung gefährdet sind. Heuschreckengemeinschaften werden hauptsächlich von der Raumstruktur beeinflusst und sind deshalb gute Indikatoren für die Habitatqualität. Die Gemeinschaften können durch das Vorkommen charakteristischer Heuschreckenarten klassifiziert werden (regionale "Leitarten" und/oder "Differentialarten" nach PONIATOWSKI & FARTMANN 2008). Als Untersuchungsgebiet diente das Aísatal in den westlichen aragonesischen Pyrenäen (Spanien). Entlang eines Höhengradienten (750–1150 m NN) wurden hier 21 Flächen untersucht. Drei Heuschreckengemeinschaften ließen sich abgrenzen: (i) die Gemeinschaft der kraut- und grasreichen Trockenrasen (Typ 1) mit der Leitart Tessellana tessellata, (ii) die Gemeinschaft der strauchreichen Trockenrasen (Typ 2) mit den Leitarten Thyreonotus corsicus und Chorthippus binotatus binotatus und der Differentialart Stenobothrus lineatus und (iii) die Gemeinschaft der steinigen Trockenrasen (Typ 3) mit der Leitart Chorthippus b. binotatus und der Differentialart Oedipoda coerulea. Außerdem wurden die Habitatansprüche der Leit- und Differentialarten analysiert: Tessellana tessellata bevorzugt homogene, hohe und dichte Vegetation, während das Vorkommen von Thyreonotus corsicus und Stenobothrus lineatus von einem heterogenen, vertikal gut strukturierten Habitat mit Kräutern und Sträuchern abhängt. Im Gegensatz dazu sind die Optimallebensräume von Oedipoda coerulea durch hohe Rohbodenanteile gekennzeichnet und das Vorkommen von Chorthippus b. binotatus beschränkt sich auf Standorte mit einer hohen Zwergstrauchdeckung.[ES]: Los pastos mesomediterráneos (alianza Aphyllanthion) constituyen hábitats de una gran biodiversidad, ahora amenazados por el abandono de las técnicas tradicionales de explotación. Las comunidades de ortópteros se encuentran muy influenciadas por la estructura de la vegetación y por ello pueden ser indicadoras de sus características. Estas comunidades pueden ser clasificadas por la presencia de "especies características" o de "especies diferenciales", siguiendo a PONIATOWSKI & FARTMANN (2008). Estudiamos aquí la composición de estas comunidades en 21 parcelas situadas a lo largo de un gradiente altitudinal, de 750 a 1150 msnm en el Valle de Aísa, Pirineo Aragonés occidental (España). Definimos tres comunidades de ortópteros: (i) una comunidad de pastos densos rica en gramíneas y otras hierbas (tipo 1) con la especie característica Tessellana tessellata, (ii) una comunidad de pastos ricos en caméfitos (tipo 2) con las especies características Thyreonotus corsicus y Chorthippus binotatus binotatus más la especie diferencial Stenobothrus lineatus, y (iii) una comunidad de pastos pedregosos (tipo 3) con la especie característica Chorthippus b. binotatus y la especie diferencial Oedipoda coerulea. Además, analizamos las preferencias ecológicas de las especies características y diferenciales: Tessellana tessellata prefiere una vegetación densa, alta y homogénea, mientras que Thyreonotus corsicus y Stenobothrus lineatus se presenta en un hábitat heterogéneo, bien estructurado verticalmente con herbáceas y caméfitos. Por el contrario, los hábitats óptimos para Oedipoda coerulea muestran una gran proporción de terreno sin vegetación y Chorthippus b. binotatus queda restringida a lugares con una alta cobertura de caméfitos.Peer reviewe

Slow response of grassland specialists to habitat fragmentation in well-connected calcareous grasslands

Due to the transition from traditional land use to modern agriculture throughout Europe, semi-natural grasslands are subject to severe environmental changes. Both agricultural intensification and abandonment have caused fragmentation of semi-natural grasslands in Europe with adverse effects on biodiversity. However, species extinction can possibly occur with a substantial delay to habitat deterioration. Meanwhile, there is increasing evidence that such time-delayed extinctions represent an essential but still less-considered challenge in the conservation of grassland biodiversity. In this study, we analyzed the effects of past and present landscape conditions on vascular plant, Orthoptera and butterfly specialists in calcareous grasslands in one of the German biodiversity hotspots and provide implications for conservation. Patch area as well as patch connectivity significantly decreased from 1970 to 2015. However, this decrease was most dramatic between 1970 and 1990; since then further habitat fragmentation is proceeding at a much lower level as a result of intensified conservation measures. Due to regular management, the studied patches were generally characterized by a high habitat quality and were still large and well-connected compared to most other regions in Central Europe. The number of specialist vascular plant and butterfly species was positively related to both past and present fragment size. However, models including past patch area performed better in both species groups. In contrast, Orthoptera specialist species richness was in neither case affected by patch area. Additionally, the number of specialist species was better explained by past than present habitat connectivity across all species groups. Our results clearly suggest that habitat specialists can persist in calcareous grasslands for several decades, despite increasing pressure of habitat fragmentation. In general, past landscape conditions were more strongly correlated to today's specialist species richness indicating the existence of an extinction debt across all species groups. Contrary to our expectations, this was also true for butterflies which are generally known to be relatively mobile and short-lived. However, due to regular management and still sufficient area and connectivity of the patches, even organisms that are more sensitive to fragmentation may persist in such well-connected landscapes. However, current patch area and connectivity were still important for the number of butterfly and plant specialists. In contrast, the current number of Orthoptera specialists within a patch seems to depend mainly on other factors such as habitat quality. Consequently, conservationists should focus on the maintenance of habitat quality in calcareous grasslands, as well as the restoration of former patches to counteract future biodiversity loss.peerReviewe
