Diversität und Integration

„Diversity Week“ bei Senckenberg


Das Motto von Senckenberg lautet „World of Biodversity„. Durch unsere wissenschaftliche Forschung untersuchen wir die unglaubliche Vielfalt der natürlichen Welt. Vielfalt macht Ökosysteme widerstandsfähiger und interessanter. Wir sind davon überzeugt, dass dies auch für das menschliche Ökosystem an unserem Arbeitsplatz gilt und bemühen uns, eine vielfältige Einrichtung mit Mitarbeitern unterschiedlicher Herkunft und aus vielen Ländern zu fördern.
In diesem Jahr feiert der Deutsche Diversity-Tag sein 10-jähriges Jubiläum. Ziel der Initiative, die der Charta der Vielfalt e.V. am 31. Mai 2012 ins Leben gerufen hat, ist es, die Anerkennung, Wertschätzung und Einbeziehung von Vielfalt in der Arbeitswelt in Deutschland voranzubringen. Organisationen sollen ein Arbeitsumfeld erschaffen, das frei von Vorurteilen ist. Alle Mitarbeiter*innen sollen Wertschätzung erfahren – unabhängig von Alter, ethnischer Herkunft und Nationalität, Geschlecht und geschlechtlicher Identität, körperlichen und geistigen Fähigkeiten, Religion und Weltanschauung, sexueller Orientierung und sozialer Herkunft. Als Unterzeichner*in dieses Diversity-Netzwerks und Organisationen, in denen Vielfalt gelebt wird, zeigt die Senckenberg Gesellschaft für Naturforschung ab Dienstag, den 31. Mai 2022 im Rahmen einer Diversity Week mit kreativen Aktionen Flagge für Vielfalt. 

Diversity

Charta der Vielfalt

Die Charta der Vielfalt ist eine Arbeitgeber*inneninitiative zur Förderung von Vielfalt in Unternehmen und Institutionen. Sie wurde im Dezember 2006 von vier Unternehmen ins Leben gerufen und wird von der Beauftragten der Bundesregierung für Migration, Flüchtlinge und Integration, Staatsministerin Annette Widmann-Mauz, unterstützt. Ziel der Initiative ist es, die Anerkennung, Wertschätzung und Einbeziehung von Vielfalt in der Arbeitswelt in Deutschland voranzubringen. 4.500 Unternehmen und Institutionen haben die Charta der Vielfalt bisher unterzeichnet und setzen sich für ein wertschätzendes und vorurteilsfreies Arbeitsumfeld ein. Der Verein repräsentiert damit 14,6 Millionen Arbeitnehmer*innen in Deutschland, darunter auch die Senckenberg Gesellschaft für Naturforschung seit Juni 2021.

Diversity

Diversitäts- und Integrationsausschuss

Diversität ist hierbei der wissenschaftliche Eckpfeiler. Senckenberg steht für Gleichstellung, Gleichberechtigung, Integration und Inklusion, sowie die Vereinbarkeit von Beruf und Familie. Wir glauben, dass die Diversifizierung der menschlichen Komponente des Senckenberg-Ökosystems unsere Stärke und Widerstandsfähigkeit erhöhen wird. Der Senckenberg Diversitäts- und Integrationsausschuss wurde Ende 2020 gebildet und ist dem Direktorium unterstellt. Es hat die Aufgabe, die Senckenberg Diversitätsstrategie zu entwickeln und umzusetzen. Zu den vielen Zielen des Programms gehört es, die Unterstützung für unsere vielfältigen Mitarbeiter*innen und Mitglieder*innen zu verbessern und die Vielfalt in unserem Engagement in der Gesellschaft widerzuspiegeln. Der Ausschuss setzt sich aus Vertreter*innen zusammen, die aus Schlüsselaspekten der Organisation und jedem der Senckenberg-Institute ernannt werden, und wird von vielen weiteren interessierten Mitarbeiter*innen in der gesamten Institution unterstützt, die zu dieser Arbeit beitragen.

Research interests

My group works on the evolution of diversity in molluscs and other marine invertebrates. Morphology shapes how each species responds to environmental change, in the modern world and in the fossil record. We often focus on very strange body forms, like bivalved gastropods, or apparently conservative forms, like chitons. We use tomography (right) to visualise animal adaptations in 3D and understand the world from other organisms‘ points of view.

Understanding evolutionary radiations, survivorship, and the way animals respond to environmental change, require high resolution data from multiple disciplines, and the research infrastructure in museum collections. The work in my research group crosses genetics, morphology, anatomy, neurobiology, physiology, computational modelling, and experimental approaches, to understand species diversity.

Some of these are discussed in my recent book, What Species Mean: A User’s Guide to the Units of Biodiversity, published by CRC/Taylor & Francis in early 2018.
