How can cleptoparasitic drosophilid flies emerge from the closed brood cells of the red Mason bee?
No full textAculeate Hymenoptera provision their progeny with large amounts of food. To protect their investment against brood parasites, females of many bee and wasp species construct brood cells that are hard to penetrate when finally sealed. However, the sealed brood cells also pose a problem for parasites that oviposit in the brood cell during provisioning. Brood parasites are smaller than their host and may lack strong mandibles to break through the solid brood cell walls. Furthermore, in nests built in existing cavities, newly-eclosed brood parasites need information about the location of the nest entrance. In the present study, the mechanisms of emergence are investigated in Cacoxenus indagator Loew (Diptera, Drosophilidae), the major cleptoparasite in nests of the red Mason bee Osmia bicornis L. (Hymenoptera, Megachilidae). Larvae of C. indagator move to brood cells closer to the nest entrance and sometimes make small emergence holes in the final closure of the nest entrance. Nevertheless, approximately one-third of newly-eclosed flies orientate and break through at least one intact cell partition to emerge. Flies make most of their attempts to emerge at the correct side (i.e. the one pointing to the nest entrance, probably by using the shape of the cell partition as a cue). Newly-eclosed flies use their head blister (ptilinum) to exert hydraulic pressure on particles of the cell partitions and produce small holes. Thus, C. indagator exhibits a set of behavioural and physiological adaptations enabling them to successfully emerge even from closed brood cells of their host

Laudatio für Herrn Dr. Martin Kaltenpoth : anlässlich der Verleihung des Förderpreises der Ingrid Weiss / Horst Wiehe Stiftung durch der Deutschen Gesellschaft für allgemeine und angewandte Entomologie am 27. Februar 2007 in Innsbruck
No full textJeder der Anwesenden kennt die Faszination, die von den Leistungen und der Vielgestaltigkeit von Insekten ausgeht. Insekten bieten eine Fülle von Beispielen für die Evolution völlig neuartiger Strukturen, Verhaltensweisen, Verteidigungsmechanismen usw. Man denke z.B. an die Evolution der Flügel, die Tanzsprache der Bienen, die Evolution hochkomplexen Sozialverhaltens oder das chemische Fachwissen der Bombardierkäfer. Besonders faszinierend wird es dort, wo Insekten mit anderen Organismen interagieren. Berühmt geworden sind die z. B. die symbiotischen Beziehungen zwischen verschiedenen Taxa von Ameisen und Pflanzen oder zwischen höheren Termiten und ihren Pilzgärten. Während Mikroorganismen meist als Krankheitserreger oder Konkurrenten für Insekten auftreten, gibt es auch einige Fälle in denen sich aus diesen negativen Beziehungen positive, ja sogar obligate mutualistische Beziehungen entwickelt haben. Dazu gehören die Darmsymbionten die von vielen Herbivoren „adoptiert“ wurden, um ihre nährstoffarme pflanzliche Nahrung besser ausnutzen zu können. Wir haben es einem der diesjährigen Preisträger, Herrn Dr. Martin Kaltenpoth, zu verdanken, dass wir seit kurzem ein weiteres aufregendes und völlig überraschendes Beispiel für eine Symbiose zwischen einem Insekt und einem Bakterium kennen

Musikstädte as real and imaginary soundscapes: urban musical images as literary motifs in twentieth-century German modernism
No full textPhDThis study examines German literary images of musical life as part of the wider sound identity of the modern German city at the turn of the twentieth century. Focussing on a forty-year period from 1890 to 1930, synonymous with the emergence of the modern German metropolis as an aesthetic object, the project assesses, compares and contrasts how musical life in the Musikstädte was perceived and portrayed by writers in an increasingly noisy urban environment. How does urban musical life influence and condition city writings? What are the differences and similarities between the writings on various musical cities? Can an urban textual sound identity be derived from these differences and similarities? The approach employed to answer these questions is a new, cross-disciplinary one to urban sound in literature, moving beyond reading the key sounds of the urban soundscape using urban musicology, sensorial anthropology and cultural poetics towards a literary contextualisation of the urban aural experience.
The literary motifs of the symphony, the gramophone and urban noise are put under the spotlight through the analysis of a wide range of modernist works by authors who have a special relationship with music. At the centre of this analysis are the Kaffeehausliteratur authors Hermann Bahr, Alfred Polgar and Peter Altenberg, the then Munich-based author Thomas Mann and the lesser known René Schickele. The analysis of these particular works is framed in the music-geographical context of the Musikstadt and literary underpinnings of this topos, ranging from Ingeborg Bachmann to Hans Mayer and, once again, Thomas Mann. In analysing these texts, the methodological approach devised by Strohm, who identifies the blending of a range of urban sounds as a definition of urban space and identity, is applied. His ideas combine historical literary
analysis, musical history and urban sociology. They are rarely used in the analysis of the auditory environment.Arts and Humanities Research Council

Effects of constant and fluctuating temperatures on the development of the solitary bee Osmia bicornis (Hymenoptera: Megachilidae)
No full textInternational audienceSince the temperature during development may affect growth and fitness in insects, climate change might affect important life history traits of solitary bees. We investigated the impact of three fluctuating and three constant temperature regimes on prepupal weight, mortality, and development time of Osmia bicornis. Prepupal weight decreased with increasing temperature, but not as strong under fluctuating conditions. Adult mortality increased in the warm treatments. Fluctuating (versus constant) temperatures accelerated development in the most stages and temperature regimes. The duration of almost all developmental phases decreased with increasing temperature, except for the prepupal phase that was prolonged in the warm treatments. The differences in thermal responses to fluctuating vs. constant temperatures illustrated the importance of fluctuating temperatures in studies investigating potential consequences of climate change for insects, including pollinators
Factors affecting offspring body size in the solitary bee
No full textBody size is related to fitness in many insects. In solitary bees offspring body size is
largely determined by maternal provisions and microclimate. We studied the effect of
quantity and quality of provisions and rearing temperatures (20, 25 and 30 °C) on body
size in the Red Mason bee, Osmia bicornis. Cocoon weight increased with
provision weight and decreased with increasing temperature. High temperature (30 °C) led
to high mortality of larvae and smaller body size, partly due to incomplete consumption of
the provisions. Diversity of pollen in the provisions was low, and most provisions
primarily consisted of mainly oak and maple pollen. Pollen diversity did not affect cocoon
weight and males provided with pure oak or pure maple pollen showed similar adult size.
Our results suggest that the quantity of provisions and temperature, but not pollen
quality influence the development of O. bicornis progeny and might affect
population dynamics of this abundant European pollinator
