After the famous Krefeld study, which highlighted a loss of 75% of the insect biomass over the last 27 years in protected areas in Germany (Hallmann et al. 2017), further scientific articles and reviews have been published on this topic (e.g., Seibold et al. 2019; Wagner 2020). Nowadays, it is obvious, that the diversity and biomass of insects are strongly threatened globally. Nevertheless, not all insect populations are decreasing. Some thermophilous species can benefit from climate change and hence expand their population size and their distribution (e.g., Roth et al. 2021). There are also examples of increasing insect populations due to successful conservation measures (e.g., Walter et al. 2017).\u0000 A comprehensive recent study published in a Swiss Academic Report (Widmer et al. 2021) concluded that conservation measures are urgently needed to avoid dramatic losses of insects and the valuable ecosystem services they provide. This is necessary for all activity sectors such as agriculture, forestry, and energy production. Among other measures, this report recommends an intensification of species monitoring and research activities in entomology, and an improvement in knowledge transfer. Our journal, Alpine Entomology, fulfills this goal extremely well. As an open-access journal, we aim at publishing inter alia research and review articles, short communications and checklists on arthropods not only from the Alps but also from other mountainous regions. In doing so, we contribute to the dissemination of knowledge on insects to a broad audience. For example, more than twenty articles published in Alpine Entomology since 2017 have acquired more than 2’000 unique views. \u0000 To improve the international impact and scientific quality of Alpine Entomology, we can now count on our recently formed editorial board. The board members will act as ambassadors for our journal outside of Switzerland, as well as support us in our strategic decisions. \u0000 Our Editorial board is currently composed of the following people:\u0000 Prof. Dr. Thibault Lachat, Editor in chief, Bern University of Applied Sciences\u0000 Dr. Oliver Martin, President of the Swiss Entomological Society, ETH Zurich\u0000 Dr. Yves Basset, Smithsonian Tropical Research Institute, Panama\u0000 Prof. Dr. Inon Scharf, Tel Aviv University\u0000 PD Dr. Seraina Klopfstein, Natural History Museum, Basel\u0000 Prof. Dr. Lyubomir Penev, Managing Director and Founder of Pensoft Publishers\u0000 We are open to extending this board by inviting a few additional members, and especially hope to recruit international researchers working in regions not currently represented.\u0000 A few weeks ago, we launched our first topical collection, a step that should also help to increase the attractivity of our journal.

Sie wurde daher per Videokonferenz abgehalten. Der Präsident Oliver Martin hatte dafür ein Meeting via Zoom organisiert, das reibungslos ablief.\u0000 Trotz der erschwerten Umstände konnte ein interessantes Vortragsprogramm für die Jahresversammlung zusammengestellt werden. Den Themenschwerpunkt bildete die experimentelle Forschung mit Hymenopteren, jedoch aus ganz unterschiedlichen Fachgebieten. Das Programm startete mit dem Hauptvortrag von Yuko Ulrich, Professorin an der ETH Zürich, zum Thema Sozialverhalten und Krankheitsdynamik bei Ameisen. Darin gab sie einen Einblick, wie im Labor soziale Interaktionen und die Mechanismen der Entstehung von Arbeitsteilung untersucht werden. Als Modellorganismus diente die räuberische Ameisenart Ooceraea biroi, die keine Königinnen ausbildet. Stattdessen vermehren sich alle Individuen parthenogenetisch, was den Faktor der genetischen Varianz in Experimenten deutlich reduziert. Mittels Kameras über mehreren Dutzend Ameisenkolonien und Farbcodes auf den Tieren konnte das Verhalten und der Aufenthaltsort (im Nest oder ausserhalb des Nests) jedes Individuums analysiert werden. Dann wurde der Einfluss der Koloniegrösse, sowie der Mischung von Genotypen und Körpergrössen innerhalb einer Ameisengruppe auf das Verhalten der Tiere untersucht. Abschliessend berichtete Frau Ulrich über die neueste Forschung mit experimentell infizierten Ameisen. Von Pilzsporen befallene Tiere werden intensiver von Artgenossen betreut, wodurch ihre Überlebensrate stark steigt. In zukünftigen Studien sollen die genannten Untersuchungen über mehrere Generationen von Ameisen hinweg ausgedehnt werden. \u0000 ● Social behaviour and disease dynamics in clonal ant colonies.\u0000 Yuko Ulrich, ETH Zürich\u0000 ● Defensive symbionts protect aphids from parasitoid wasps depending on stable genotype-by-genotype interactions.\u0000 Elena Gimmi, Eawag / ETH Zürich\u0000 ● Megachile sculpturalis Smith, 1853 (Hymenoptera: Megachilidae), an Asian wild bee populates Europe. \u0000 Julia Lanner, Universität für Bodenkultur Wien / Universität Bern\u0000 ● Homemade or take away: Where do the cuticular hydrocarbons of parasitoid wasps come from?\u0000 Corinne Hertäg, ETH Zürich\u0000 ● Entwicklungsbiologische Ursachen sexueller Merkmale bei Mistkäfern: Wie macht man lange Beine?\u0000 Patrick Rohner, Indiana University\u0000 Der ETH Zürich sei für das Zurverfügungstellen des Videokonferenzraums herzlich gedankt.","PeriodicalId":36427,"journal":{"name":"Alpine Entomology","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2021-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47638298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although males typically transfer many sperm during copulation, only a small proportion reach the fertilization site because females often actively or passively reduce sperm number in their reproductive tract. Males may transfer accessory substances to protect their ejaculates against female selective processes, which benefits males but can harm females. In turn, females may use accessory gland fluids to control paternity or sperm storage. Female yellow dung flies (Scathophaga stercoraria) have paired accessory glands that produce fluids involved in fertilization and egg laying. One proposed function for these fluids is spermicide. Alternatively, female accessory gland fluid may help keep sperm alive to avoid fertilization failure or encourage sperm competition. Using yellow dung flies, we investigated the interaction of female accessory gland fluid with sperm in vitro. Significantly more sperm remained alive when exposed to accessory gland fluid compared to buffer only (63% vs. 44%). We conclude that female accessory gland fluid in yellow dung flies can help nourish rather than kill male sperm, although selective nourishment of sperm is as consistent with cryptic female choice as is selective spermicide.","PeriodicalId":36427,"journal":{"name":"Alpine Entomology","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2021-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47303135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Blanckenhorn","doi":"10.3897/alpento.5.68153","DOIUrl":"https://doi.org/10.3897/alpento.5.68153","url":null,"abstract":"Foraging provides the basis for animal reproduction, but requires energy and time to be sustained, entailing a trade-off. Whereas females should maximize their time foraging for resources, males should minimize their foraging time by optimizing time budgets to maximize their access to mating partners. Mark-resight field studies are difficult and hence uncommon for small insects. Yellow dung flies (Scathophaga stercoraria L.) abound on pastures in cold-temperate regions across the northern hemisphere. Adult flies lick nectar from flowers for energy, but require small insect prey to produce eggs and sperm. Males wait for females around fresh cow dung, but at one point also need to replenish their energy and/or sperm reserves in the surrounding vegetation. Their foraging time budgets should depend on their body size, nutritional energy reserves, availability of sperm, competitor and female density. Marked male dung flies whose nutritional status was experimentally manipulated – water only (null control); water + sugar (energy replenishment); or water, sugar + Drosophila prey (energy and sperm replenishment) – were repeatedly observed on an experimental pasture for an entire day. Both nutrient types were expected to increase the mating success of especially large males. The total number of resighted males seen copulating was lowest for water-treated flies. Mating success was positively related to body size. The distance travelled between dung pats was greater for males fed sugar or prey and also increased with body size, while pat residence times decreased with size. No differences were found between the sugar- and prey-fed groups. Crucially however, there was no evidence in the field for a time budget or mating advantage of small males when nutrients were limited.","PeriodicalId":36427,"journal":{"name":"Alpine Entomology","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70393700","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
