Project Title: Modelling context-dependent shifts in the forms of symbioses

Project Description: Symbiotic interactions - representing prolonged physical associations of several species - are common in natural systems and can determine population dynamics, species persistence and ecosystem functioning, as demonstrated for example in coral reefs and plantpollinator networks. Symbiotic interactions can take different forms including parasitism, mutualism and competition.
Depending on the underlying costs and benefits of the symbiotic interaction, the form of symbiosis may shift between different types of species interactions, e.g. mutualism and predator-prey interaction (see figure). While recent work has shown that the costs and benefits of symbioses depend on the densities of the symbiosis partners, we currently lack an understanding of how the form of symbioses depends on species traits and the overall food web context. This is particularly important as individuals and populations may adapt their traits to altered environmental conditions and as the food web structure may strongly vary across time and space. Hence, we want to improve general theory in community ecology by accounting for context-dependent changes in the form of symbiosis including the species’ potential to adapt to altering conditions in a food web context.

The project is embedded into a network of experimental and theoretical working groups across Germany, conducting regular workshops and meetings promoting international networking. The prospective PhD student will join the working group of Prof. Dr. Ursula Gaedke, jointly supervised by Dr. Toni Klauschies. The prospective PhD candidate has the opportunity to closely interact with an experimental PhD student addressing the same overarching topic in our working group and related research groups on Campus. They can join the Potsdam Graduate School (PoGS) allowing for a broad interdisciplinary training of soft skills and early career development. The unique location of our campus in Park Sanssouci is part of a historical place in Potsdam
providing a fruitful scientific environment and good working atmosphere.

Your qualification: MSc degree in Ecology or other relevant subjects such as Physics, Mathematics or Environmental Science. We are seeking enthusiastic and committed candidates who enjoy ecology and applied mathematics with a solid background in ecology and ecological modelling. The successful candidate is expected to implement and analyze numerically differential equation models with a modern programming language such as Python, MatLab or Mathematica. Very good English writing and communication skills are expected, German is an asset but not essential.

Application: To apply, please send the following documents as a single PDF to gaedke@uni-potsdam.de (the position is open until it is filled)

Project Title: Context dependent effects on protective symbiosis driven by predation, competition and parasitism

Project Description:
Symbiosis is a biological interaction which refers to the physical association of individuals from different species that can be positive, negative or neutral to either species. In planktonic systems several symbiotic interactions can occur simultaneously and can interact with each other. We want to study the symbiosis between Daphnia and the rotifer Brachionus rubens within a multi-species interaction web. B. rubens can attach to Daphnia which reduces the fitness of Daphnia. At the same time both species compete for resources (algae). The
attachment becomes more relevant, when a predator of B. rubens, A. brighwelli (another rotifer) is present because attached B. rubens are protected from predation. The aim is to quantify the costs and benefits for Brachionus and Daphnia under varying conditions and to better understand symbioses in a community context. Thus, the present project will contribute to a new food web theory which includes density dependence of symbioses. In addition, video analyses will be performed to study the attachment process in more detail.

In the case of final approval, the project is embedded into a network of several experimental and theoretical working groups across Germany conducting regular workshops and meetings.

The prospective PhD student will join the working group of apl. Prof. Dr. Guntram Weithoff at the University of Potsdam. We provide an active research  environment covering a broad range in ecological research. Beyond that, the Potsdam Graduate School (PoGS) offers a broad program on interdisciplinary training in soft skills and early career development.

Your qualification: MSc degree in Ecology preferably in Aquatic Ecology or a related field. We are looking for a motivated candidate with good experimental skills. Further relevant skills are: sound knowledge in conceptional ecology, statistics and very good English in writing and communication.

Application: To apply, please send the following documents as a single PDF to weithoff@uni-potsdam.de (the position is open until it is filled):
• Cover letter, including a statement of motivation and from when on you would be available
• Curriculum vitae including information on relevant skills
• Certificates of education
• If possible, provide letters of recommendation from previous supervisors

I am looking for a PhD student to join my research group at the Max Planck Institute for Evolutionary Biology. The position is part of the Collaborative Research Unit 'Density dependent symbiosis in planktonic systems – DynaSym', which brings together several research groups across Germany to test and develop basic concepts of density dependence of the symbiosis form (e.g., shift from predator-prey to mutualistic interaction and back).

Modeling parasite epidemics in host populations with symbiont-mediated immunity

Protective symbionts can provide hosts with immunity against virulent parasites. Yet, symbionts themselves may also be costly for the host. The form of symbiosis is thus context dependent: mutualistic upon exposure (or infection) with the virulent parasite but parasitic in its absence. Classical theory on host-parasite systems only considers two players -- the host and the parasite. The possibility of protective symbiosis clearly demonstrates the need for theory that goes beyond two-species systems. In this project, we will develop theoretical models to study the joint changes in the densities of hosts, symbionts, and parasites and the associated changes in the form of symbiosis. Initially, we will mostly develop general theory, but we will later also explore models that match the biology of Daphnia and its parasites. In collaboration with other members of the Research Unit, models can moreover be tailored to other systems of protective symbiosis that are studied empirically within DynaSym.

The ideal student is interested in applying mathematical modeling to gain insights into biological problems, enthusiastic about math as well as about biology, and excited about engaging in the research unit DynaSym. The student will learn how to set up and analyse theoretical models to describe biological processes and profit from close interactions with empirical researchers. Applicants should have a background in mathematics, physics, biology, computer science, or a related field. Good quantitative skills are essential. Prior experience in mathematical modeling and knowledge of a programming language (C, C++, Java, Python, Julia...) is an advantage.

The Research Unit DynaSym has recently been funded by the German Research Foundation DFG (www.uni-konstanz.de/en/university/news-and-media/current-announcements/news-in-detail/mal-freund-mal-feind) and is a collaborative initiative bringing together research groups from across Germany and international collaborators. 8 projects will collaborate within the research unit and cover experimental work with plankton systems, modeling, theory development, and synthesis work. Workshops, retreats, and research visits to other research groups are planned for all participants to facilitate exchange and additional training.

Working environment
The student will join the research group 'Stochastic Evolutionary Dynamics' at the Max Planck Institute for Evolutionary Biology. The group is part of the Department of Theoretical Biology. The student will hence be part of a community of researchers working at the intersection of mathematics and biology with many opportunities to take part in journal clubs, reading groups etc.
The Max Planck Institute is a lively institute with around 180 employees from more than 30 nations. There are currently two departments (Theoretical Biology and Microbial Population Biology) and several additional research groups. It hosts several workshops per year and continuously welcomes international short-term and long-term visitors, creating a stimulating and positive research environment. We maintain close interactions with Kiel University and belong to the Kiel Evolution Center. The area is a center of evolutionary biology in Germany.

Plön
Plön is a small town, embedded into a beautiful landscape with numerous lakes and close to the Baltic Sea. The area provides ample opportunity for free time activities such as swimming, canoeing, or biking in a stunning environment. At the same time, the cities of Kiel and Lübeck (≥200,000 inhabitants) are only half an hour train ride away. Hamburg (Germany’s second largest city) can be reached within 1.5h by train.

Application
Interested students should send their application (motivation letter, CV, copies of certificates, contact details of two references) in a single pdf by email to uecker@evolbio.mpg.de and to bewerbung@evolbio.mpg.de. Please use the code PhD2024 in the subject line. We ask you to refrain from including a photo on your CV.
