Phoresie bei Hornmilben: Chemische Schlüsselreize in Milben-Borkenkäfer-Interaktionen

Kurzzusammenfassung Schädlinge sind in der Forstwirtschaft eine immer größer werdende Gefahr. Speziell die Borkenkäferpopulationen drohen durch das mildere Klima zu explodieren. Ein Aspekt der biologischen Schädlingsbekämpfung stellt das Phänomen der Phoresie dar. Sie ist eine an sich harmlose Form des Transportes. Dabei nutzt ein wenig mobiles Tier ein größeres, mobiles Tier zur Ortsveränderung. Durch massiven Befall des Transporttieres kann dieses jedoch stark an Mobilität verlieren, was ferner eine Möglichkeit der Schädlingsbekämpfung darstellt. Diese Arbeit untersucht chemische Schlüsselreize in Hornmilben-Borkenkäfer Interaktionen. Wie erkennt die phoretische Milbe ihren spezifischen Wirt? Dazu wurde die folgende These formuliert, dass es die charakteristische Kohlenwasserstoffverbindung an der Cuticula des Buchdruckers (Borkenkäferart) ist, welche es Paraleius leontonychus (Hornmilbenart) erlaubt, diese mittels Chemorezeptoren wahrzunehmen. Zwei unterschiedliche Borkenkäferarten wurden herangezogen und deren Oberflächenzusammensetzung durch Extraktion in Hexan eruiert. Die Komponentenzusammensetzung sowie die Komponentenmengen wurden hierbei verglichen. Durch Verdünnung der Komponenten konnte eine naturgetreue Mischung der drei signifikantesten Duftstoffe des Buchdruckers hergestellt werden. Danach wurde ein Versuchsaufbau installiert, in welchem Dummys mit den Duftstoffen des Buchdruckers beimpft wurden. Die Duftstoffe wurden einzeln und in verschiedenen Kombinationen auf die Dummys aufgetragen. Es konnte nachgewiesen werden, dass es tatsächlich dieses charakteristische Kohlenwasserstoffmuster ist, welches in Verbindung mit einer geeigneten Oberflächenstruktur dazu führt, dass die Milbe den richtigen Wirt erkennt.Abstract Pests are an increasing danger for forestry. The population of bark beetles particularly seems to explode due to benign climate. One aspect of biological pest control is phoresy, which is a harmless form of transportation: one animal uses another, more mobile one to change its location. If numerous animals use the same transporter and the attack gets massive, the transport animal loses its mobility. This fact represents a possibility of pest control. This research paper examines chemical stimuli within the interaction between armored mites and bark beetles. How does the phoretic mite recognise its specific host? Therefore I formulated the following theses: “The characteristic hydrocarbon compound of Ips typographus`s cuticula enables the Paraleius leontonychus to recognise their host via chemoreceptors.” Two different kinds of bark beetles and their surface structure (which got determined via extraction in hexan) were used for this research. Subsequently I compared the components of both surface structures and the amounts of components. A true to life mixture of the three most significant fragrances of Ips typographus could be produced by diluting those components. In the following an experimental setup was installed and I vaccinated dummies with those fragrances - some of the fragrances separated and others in different combinations. This research proved that it was in fact the specific pattern of hydrocarbon compounds, and a suitable surface, which enables the mite to find its host.vorgelegt von Philip IslitzerZusammenfassungen in Deutsch und EnglischAbweichender Titel laut Übersetzung des Verfassers/der VerfasserinKarl-Franzens-Universität Graz, Diplomarbeit, 2018(VLID)258176

Als mehrperspektivisches Zusammenspiel von kunstbasierten und kreativen Strategien sowie Praktiken der Kommunikation und Organisationsentwicklung wird «Kreagilität» durch die Erfahrungen von Menschen in unterschiedlichen Rollen, Situationen, Kontexten und Öffentlichkeiten bereichert und stimuliert. Die intuitiven und systematischen Arbeitsweisen der Kreagilität zeigen sich in Situationen von Überforderung, Unsicherheit und Komplexität besonders wirkungsvoll. In diesem Workshop experimentieren wir mit «Kreagilem Handeln» und entwerfen gemeinschaftlich unkonventionelle Herangehensweisen für mehrdeutige, oftmals widersprüchliche Herausforderungen.

"What is Creative Agility?"

1. Collaboration Topic Within the framework of the Erasmus+ project on Creative Agility (2021 - 2023), an international pro-ject team consisting of artists, mediators and scientists from Liechtenstein (Kubus Kulturvermittlung Balzers, overall management), Switzerland (ZHAW Zurich University of Applied Sciences, lead scientific accompanying research), Austria (SPES Zukunftsakademie Schlierbach) and Germany (HKS University for Arts in the Social Ottersberg) is currently exploring how art-based strategies transform digital and analog communication in organizations. In the wake of Practice and Narrative Turn , "Communication Constitutes Organization" paradigm as well as narratological management and organizational research , practice routines such as leadership, management, entrepreneurship and consulting have become communicative tasks . Increasingly, de-sign practices as well as arts-based strategies, methods, and interventions are being used to create narrative effects and impact in organizations. The development and research project outlined here is situated in the field of adult education and specifically permeates the following themes of the ADMC conference: - Design Leadership with a view to organizational transformations through the integration of art-based strategies and interventions, design practices and methods in organizational contexts; Sci-entific accompanying research of a case study as well as pilot trainings/market tests in Europe by means of (practice-theoretical and) approaches from discourse and design research . - Design for the Public Good with a view to the development of a future-oriented training on Crea-tive Agility for executives and decision-makers in different contexts such as business, politics, society, health, etc. incl. accompanying scientific research (case study and pilot trainings/market tests in Europe using (practice-theoretical and) approaches from discourse and design rese-arch ). 2. Short Description of Project, R+B Research and Partnership How do dialogue, collaboration and participation succeed in situations of volatility, uncertainty, comple-xity and ambiguity? The VUCA world in which we live today is constantly putting us to the test. It fun-damentally reshapes our lives, our interaction and communication. Working, decision-making and com-munication processes must be rethought and reestablished. We are constantly discovering, trying out and reflecting on how we function in communicative interaction. This creates uncertainty and anxiety, because social practices and forms of cooperation are constantly being renegotiated. Everything is changing - permanently. How do we react to this change and how do we shape it communicatively as people in different functional roles, as teams, as organizations, as a society? Why Creative Agility? The project team sees Creative Agility as a key competence for navigating complex working environments - digital and analog. Organizational development is not just a questi-on of technical skills, but of the ability to break through decision-making, communication and lea-dership routines that have become deficient, to face situations with Creative Agility and to communi-cate effectively. Can this ability be trained? And can it enrich "creagile" transformation processes in organizations? These are the questions the international project team is addressing. Project goals: Together, the project partners are developing a training course on Creative Agility that will enable people to face volatile, uncertain, complex and ambiguous situations in a "creagile" way and to actively shape organizational and social transformations. The training focuses on the way participants communicate without explicitly pointing this out at the beginning. Creative Agility does not function in isolation from, but rather embedded in, constructive and benevolent analog and digital communication behavior. Through "creagile" communication, decision-making, change and organiza-tional processes can be accelerated and improved. The aim of the project is to develop a curricular training concept in the form of a modular art-based, knowledge-oriented and methodological-didactic kit including various training materials. In addition, pilot trainings (market tests) in Europe and expe-riments with digital and analog learning formats will be realized. The training materials developed in German will be translated into English, French and Italian after completion of the project. The project budget amounts to EUR 322'000. Observing, linguistically capturing and designing Creative Agility: An important basis for the joint development of the training is the scientific accompanying research of the Erasmus+ project on the part of the ZHAW, specifically a case study realized in winter 2021. As a communication, dis-course and design researcher, Birgitta Borghoff observed how Michael Uhl, freelance director and lecturer at the HKS Ottersberg, worked artistically with local decision-makers in the German com-munity of Ottersberg (near Bremen). In the process, she was able to witness how politically active, artistic and academic actors behave towards the big complex questions in the context of narrowly defined competencies. They did this using the example of the topic "economy/growth and ecology". Together, the participants explored how they deal with permanent over-complexity in their respective roles on the basis of a concrete project on housing densification. In doing so, they explored the question of how political mediation can succeed when answers to facts or questions are not immedi-ately available. The theater-based artistic method of the "Narrative Recherche" developed by Michael Uhl himself was applied. The result was a collection of narratives and perspectives of the participants, which were brought together as a mosaic in an artistic form. Currently, the ZHAW is evaluating the effect of the "Narrative Recherche" on the participants from the council, administration, art and science. In addition to the evaluation of the observation protocols of the artistic interventions in Ottersberg, narrative group interviews were conducted with the council and administration of the Ottersberg municipality as well as with actors of the HKS Ottersberg. The interviews were transcribed verbatim. In addition, summary protocols of individual interviews with the Ottersberg population were prepared. As part of a research-based teaching project, Birgitta Borghoff is evaluating narrative patterns and practices of language use together with communication students at the ZHAW. Linguistically it is reconstructed what the actors participating in the process say and how they behave (discourses ). How does the process take shape? What practices and social routi-nes can be identified? What histories, conflicts and themes emerge? And what can we learn from this with a view to transferability to similar situations, other organizational and social contexts, and discursive simulations of desirable futures ("design fiction" )? Our contribution in the R+B track at ADMC 2022 presents firstly results of the discourse analytic case study in Ottersberg and how we integrate them into the development of a guide for implemen-ting artistic interventions in organizations as well as into the training on Creative Agility. Second, there will be multi-perspective insights into the experiences of the project partners during the first pilot training/market test in Liechtenstein (May/June 2022) as well as during a first Swiss multiplier event at the ZHAW (June 2022). Here we will share the current status of our results and learnings with a broad Swiss public. At the ADMC, you can expect a variety of insights into an exciting Eras-mus+ project and conversations with artistic, mediating, researching and teaching project partners. - An exciting opportunity to experience Creative Agility live
