Anticipation of Critical Transitions in Complex Systems

15.08.2017
Complex systems are known to show at tipping points abrupt changes in their macroscopical behavior under smooth parameter variations. In recent years the identification and anticipation of tipping points of complex systems from measurement data received much attention in the scientific community. One approach relies on the general theory of complex systems and the result that close to tipping points systems that are formed by the nonlinear interaction of many subsystems show universal features. Although the constituting parts can be very different they all show phenomena like for example critical slowing down or critical fluctuations. This can be observed in a wide variety of systems from different scientific disciplines starting from Laser physics over pattern formation in chemical reactions, biological and medical systems and also in psychology. In the mathematical description of these phenomena the universality is reflected by the fact that close to such critical points the dynamics of very different systems can be described by the same basic types of equations. This universal behavior is the foundation of many of the current approaches to develop indicators for tipping points for ecological and social systems even in cases where modeling of the system of interest is difficult or up to now not possible. The intention of this workshop is to give an overview over recent developments in this field. The talks cover topics from such diverse fields as ecology, neuro science and physics.

Organizers of this workshop are Arndt Telschow & Oliver Kamps.

Transversal dams prevent migration of aquatic organisms such as fish and macroinvertebrates. A current student project (Bsc. Biosciences, Msc. Water Sciences) supervised by the Limnology group of the IEB investigates the present ecological status of the structurally modified lowland river Bever near Ostbevern (North Rhine-Westphalia, Germany). Restoration measures starting in Autumn 2017 aim at achieving the „good ecological status“, as required by the European Water Framework Directive (WFD). To accomplish this goal the migration barriers (picture) will be removed and natural substrates such as wood will be placed to allow diverse morphodynamic development and free migration of the fauna. An accompanying monitoring will show whether a benthic community typical for sandy lowland streams will establish. Read more about the WFD...

Digging into the harsh world of ants

Foraging is a risky task, in particular for an ant in the desert. Kwapiche et al. (2017) showed that individual colonies of Veromessor pergandei turnover up to 34,000 foragers in their peak foraging months. Overall forager population turned over approximately 20 times during the year, cumulatively returning 3.4 kg of biomass (in ants) per hectare. Surprisingly, colonies where the queen mated with fewer males did better than colonies where the queen mated with multiple males.

On June 13th, 2017 the annual Rensch Lecture was given by Prof. Diethard Tautz from the Max Planck Institute for Evolutionary Biology in Plön in the Aula of the Schloss. Prof. Tautz talked about the controversial hot topic of, if and how it is possible that completely new genes, so called "de novo" genes, emerge from previously non-coding regions on the DNA instead from gene duplications, which was hitherto considered to be the only major source of novel genes. His lecture with the title "Gene aus dem Nichts - wie in Zufallssequenzen genetische Information entsteht" was well attended and spurred a lively discussion.

24.03.2017
Different software components developed in the Evolution and Biodiversity of Plants group work together to allow scientist to attach and visualize metadata of their research data. Annotating scientific data with semantic information in a machine readable way becomes increasingly important in the age of big data and the semantic web to ensure (automated) accessibility and reusability. The poster “Increasing data accessibility and reuse in phylogenetics by employing externally defined ontologies” presented at the MGSE symposium shows the concept in detail.

Further information on the presented software:

  • JPhyloIO - A Java library for event-based reading and writing of different phylogenetic file formats through a common interface
  • LibrAlign - A GUI library for displaying and editing multiple sequence alignments and attached data
  • TreeGraph 2 - A feature rich and easy to use phylogenetic tree editor
  • More software developed in the Evolution and Biodiversity of Plants group

Paper on the evolution of protein domain repeats by Andreas Schüler

01.12.2016
A paper on the evolution of protein domain repeats by PhD student Andreas Schüler (who graduated since) appeared in "Journal Molecular Biology and Evolution". The study titled "Evolution of Protein Domain Repeats in Metazoa" describes how, over evolutionary very long time scales, repeats of functional and structural units, so called domain, evolve by duplication and loss or insertion of domains. Repeats are notoriously complicated to capture for all algorithms and cause many sequencing mistakes but it is important to understand their coming about because repeats are involved in many cellular disorders and implicated in diseases, e.g. in neurodegenerative diseases.

Andreas characterised repeats according to their structure and inferred the mechanisms which underly their sometimes fast but mostly much slower than previously thought evolution.

We want to welcome Prof. Dr. Jürgen Gadau as the head of the Molecular Evolution and Sociobiology Group at the Institute for Evolution and Biodiversity. He got his PhD at the University of Würzburg in 1997 and later worked as a Feodor-Lynen PostDoc at the University of California in Davis. After his stay abroad he habilitated in 2004 in Würzburg under Prof. Bert Hölldobler and accepted a position as an Assistant Professor at the Arizona State University in 2004 where he was an integral part of the Social Insect Research Group and Center for Social Dynamics and Complexity for 12 years. Since November Jürgen Gadau now holds the professorship for Molecular Evolutionary Biology at the IEB. He is also involved in the Münster Graduate School of Evolution (MGSE) as one of many PIs.

This is what he says about his research interests:
"We are using social (ants and bees) and solitary insects (parasitoid wasps like Nasonia) to understand the genetic basis and regulation of adaptive traits across multiple levels from gene to colony and time frames from seconds to millions of years. A major challenge for the future is to map genetic, genomic and epigenetic variation to observable phenotypic variation and understand how these traits evolve."

Jonathan Schmitz gets awarded the annual Rensch price for his master thesis. In his thesis, Jonathan analysed the evolution of transcription factor families in Metazoa and found out that these families evolve via single gene as well as whole genome duplication and that their functional diversification is facilitated by reshuffling of protein domains, conserved  blocks of protein sequence. The thesis resulted in the publication of a paper in Nucleic Acid Research.





Nachruf

Wir nehmen Abschied von unserem plötzlich und viel zu früh verstorbenen Kollegen, Dozenten, Mitarbeiter und Freund

                                                                     Dr. Joachim Röschenbleck

Mit außergewöhnlichem Engagement und enormer Kompetenz war Joachim Röschenbleck viele Jahre als Wissenschaftlicher Mitarbeiter im Botanischen Garten der Universität Münster und in den Instituten für Evolution und Biodiversität und Biologie und Biotechnologie der Pflanzen tätig.

Durch beharrlichen Einsatz und große Leidenschaft für seine Tätigkeit konnte er nicht nur wesentliche Erkenntnisse zu seinem Forschungsfeld beitragen, sondern auch viele Impulse zur stetigen Weiterentwicklung des Botanischen Gartens geben.

Den Besuchern des Botanischen Gartens war Joachim nicht zuletzt durch seine unzähligen und exzellenten Führungen bekannt. Besonders beeindruckten hierbei seine außergewöhnlichen Pflanzenkenntnisse, wie sie in diesem Umfang inzwischen äußerst selten geworden sind. Dabei vermochte er sein Wissen immer auf sehr unterhaltsame und eindrückliche Weise zu vermitteln. So konnte er auch die Studierenden auf Führungen, Exkursionen und in Praktika für botanische Inhalte und Fragestellungen begeistern und hinterlässt als geschätzter Dozent auch in der universitären Lehre eine große Lücke.

Seine immer lebensfrohe, hilfsbereite und kollegiale Art wird uns allen sehr fehlen.
Unser aufrichtiges Mitgefühl gilt den Angehörigen. Tief betroffen trauern wir mit ihnen um Joachim.

Mark C. Harrison and Evelien Jongepier have started as postdoctoral researchers on the Research Unit project "Sociality and the reversal of the fecundity/longevity trade-off". Using comparative genomics, they will unravel fecundity/longevity trade-offs in social insects and their non-social relatives. A hallmark of ageing is the trade-off between fecundity and longevity, although reversals of this trade-off independently evolved in several distant social insect taxa. Indeed, highly fecund individuals in ants, bees and termites can live up to two orders of magnitude longer than their sterile workers. Uncovering the molecular basis of this escape from ageing will provide a deeper understanding of the fundamental biological rules governing fecundity, longevity, senescence, and health.

The German Research Foundation (DFG) has funded the Research Unit Sociality and the reversal of the fecundity/longevity trade-off, an interdisciplinary collaboration including the Bornberglab. The research unit will address the fundamental questions in biology "Why do organism age?" and "Why do individuals vary in life expectancy?" A hallmark of ageing is the trade-off between fecundity and longevity, although reversals of this trade-off independently evolved in several distant social insect taxa. Indeed, highly fecund individuals in ants, bees and termites can live up to two orders of magnitude longer than their sterile workers. Uncovering the molecular basis of this escape from ageing will provide a deeper understanding of the fundamental biological rules governing fecundity, longevity, senescence, and health.
