2-year postdoctoral fellowship to work on the calibration of climate model parameters using data assimilation
Summary of the project
General Climate Circulation Models (GCMs) have evolved considerably over the past decades through the successive addition of new components, an increase in spatial resolution, and the development of new physical parameterisations. Despite these developments, systematic biases remain in these models. For example, most models simulate sea surface temperatures (SST) that are too high in the Southern Ocean and too low in the North Atlantic, for reasons that remain poorly understood. SCOOT aims to understand the origin of, and ultimately reduce, biases in SST in the North Atlantic through approaches inspired by statistics and data science. Specifically, by proposing new methods for parameter calibration inspired from recent advances in data assimilation, SCOOT will offer credible alternative pathways to the manual tuning of GCMs. SCOOT is designed as a proof of concept for introducing new best practices in the evaluation and calibration of GCMs, ultimately applicable to configurations currently under development, such as very high-resolution eddy-resolving simulations.
Work description and profile sought
The successful candidate will develop a parameter calibration approach based on an ensemble Kalman filter in the global climate model EC-Earth3. He/she will first test the validity of the approach by performing “twin experiments” in which the model’s own data is assimilated. Then, he/she will assimilate real observations of satellite SST in the North Atlantic to determine the set of parameters leading to the lowest model biases in the region. He/she will finally make a critical evaluation of the results, including a thorough assessment of the benefits of the approach in other oceanic basins. The successful candidate should have a PhD in climate modelling and/or data assimilation or related fields. Advanced programming, post-processing and data management/analysis skills are required. He/she should be fluent in English due to the multiple interactions planned with other project partners and should have demonstrated ability in team working.

A Postdoctoral researcher position, for 1 year, on simulation modelling of learning in insects in changing environments
The researcher will contribute to the ARC (UCLouvain funded “Action de recherche concertée”) project “ Learning as a key driver of adaptation to human-induced rapid environmental change: a behavioural biogeographic approach. Contracts will be based on Belgian regulations, depending on prior research experience, and will include the benefits of the Belgian social security such as health insurance. This offer is also published on Euraxess.
Objectives: To elaborate a generic individual-based model to conceptualise and explore the potential role of learning in how animals deal with rapidly changing environment
Research description: The project investigates how learning in insects, specifically in butterflies, can play a role in their responses to rapid environmental change. Learning is gradually being recognised as much more widespread than previously assumed. Many existing distributional models do not account either for such flexible behaviours nor for environmental dynamics as interacting with habitat use and colonisation. Our particular research aims at elaborating a conceptual model and implementing an individual based model that will assess the potential role of learning in insects in persisting and potentially spreading in rapidly changing environments, with a focus on land use. The model will aim at covering a species of interest in the project, the speckled wood butterfly Pararge aegeria, but will also explore other arthropod species such as disease vector mosquitoes and/or ticks, for which such questions are only just about emerging.
Profile required: A researcher holding a PhD degree, experienced in individual based and simulation modelling with a strong background in ecology, ideally with an interest in environmental monitoring. Experience with disease vectors is an asset and interest in them a necessity. The candidate should demonstrate an excellent command of the English language, good communication skills, and ability to work in a research team and to establish a local and international network.
Work environment: The researcher will join a team working on the geography of health phenomena using a range of modelling tools and on a diversity of systems, and will interact closely with project members focused on ecology. All teams are part of the Earth & Life Institute (UCLouvain, Louvain-la-Neuve, Belgium) that carries a broad diversity of environmental an biodiversity research.
The position is planned for 1 year, with possibilities for extension depending on funding availability. Candidates should submit a cover letter detailing qualifications and research interests, CV with full list of publications, and names and contacts of three referees to: Prof. Sophie Vanwambeke – sophie.vanwambeke@uclouvain.be Review of applications will start on February 1st, 2021. Starting date: As soon as possible
Postdoc position in Evolutionary Ecology
We are looking for highly motivated candidates to apply for a 2-year postdoctoral position, funded through UCLouvain university (“Action de recherche concertée”), in the laboratory of Prof Caroline Nieberding (https://nieberdinglab.be/, UCLouvain, Belgium).
Animals were long thought not to learn. Over the years research has, however, revealed that most animals do learn to some extent. This paradigm shift has led to the hypothesis that learning is a form of behavioural plasticity that participates to rapid adaptation of natural populations in nature, in response to human induced habitat degradations. Yet, the adaptive value of learning remains rarely quantified so far. This project will quantify the adaptive value of learning in the field in a number of butterfly species facing increasing reduction and fragmentation of suitable habitats. Butterflies are flagship and bioindicator species of the quality of European natural habitats, and we have occurrence data spanning several decades. This project aims at providing one of the first field-based estimates of the selective value of learning for a key behavioural trait, oviposition site selection (“OSS” hereafter). OSS is key to colonisation of suitable habitats in butterflies, the larvae of which have only a low mobility. As learning is costly, we expect that increased learning and memory skills are correlated to reduced survival and/or egg production and we will quantify potential trade-offs associated with learning and memory.
The postdoctoral research will include experiments in the field in Belgium and ecologically-relevant experiments in the laboratory, where field-caught animals can be monitored. The ideal candidate for this position will have a strong background in behavioural ecology, statistical analyses, expertise in butterfly ecology and a capacity for creative and critical thinking. The candidate will have opportunities to learn some of the specific skills required for the project by our network of national and international collaborators. Applicants should hold a PhD diploma. The deadline for applications is December 15th, or until the application is filled.
The salary will be around 2000 euro netto per month plus benefits (health insurance,…) which are included in the Belgian system. Our University is an Equal Opportunity/Affirmative Action Employer, and is in a French-speaking region of Belgium, but the language for meetings and scientific interactions is English. For background information about our university, see https://uclouvain.be/en/index.html. Applications should be sent to Prof. C. Nieberding (caroline.nieberding@uclouvain.be).
Applications will include: 1) a motivation letter including a statement of interests; 2) full CV including list of publications; 3) Contact details of at least 2 referees. Informal inquiries are welcome. We will start reviewing applications as they arrive until the appropriate candidate is selected, and the project will be starting in Spring 2021.
MixForChange – PhD Fellowship
MixForChange: Mixed Forest plantations for climate Change mitigation and adaptation
PhD scholarship in agricultural science and bioengineering
Université catholique de Louvain is offering a PhD scholarship in agricultural science and bioengineering with expected commencement March 2021 or as soon as possible thereafter.
Project title: Effects of mycorrhizal fungi on C, water and nutrient availability to trees growing in single or mixed-species communities.
PhD Project description
Mycorrhizal fungi (either arbuscular mycorrhizal fungi (AMF) or ectomycorrhizal (ECM) fungi) are key soil microorganisms associated to the vast majority of agricultural, horticultural and forestry plants, improving their growth and resistance to abiotic and biotic stresses. They are thus of wide importance in agricultural/forestry practices. Their role in carbon, water and nutrient cycling is of paramount importance, particularly under conditions of climate change. Within this thesis, communities of mycorrhizal fungi that comprise single to several species will be grown in greenhouse in association with mono or mixed tree-species communities to test the hypothesis that changes in mycorrhizal community modify (i) the total pool of available resources and water, and (ii) the way this pool is redistributed between the tree species. We will also test the hypothesis that a community of mixed tree species connected with a single fungus will better exploit/redistribute nutrients and water than a community that comprises one single tree species connected with the fungus. The mesocosm experiments will be conducted under contrasting conditions of nutrient and water availability.
The PhD position is associated to a larger European project, MixForChange, funded by the European Commission for 36 months.

Brief description of MixForChange
Forest landscape restoration and afforestation have recently received much international attention as a crucial opportunity for mitigating climate change (CC). In the face of CC, adaptation and mitigation by forests are ultimately linked, because the ability of forests to sequester carbon (C) in the long run depends on the ability of trees to cope with multiple stresses. A growing body of evidence suggests that mixed forest plantations, i.e., plantations where several tree species are mixed, are more efficient in sequestrating C, while better coping with CC-related stress. Mixed plantations thus represent an opportunity for an important nature-based solution for CC mitigation and adaptation.
However, monocultures still dominate the world’s forest plantations. One of the possible factors that may have prevented the expansion of mixed plantations at large scales is insufficient scientific evidence for practitioners and policy-makers. Using a global network of forest biodiversity experiments (TreeDivNet), we will provide a mechanistic understanding of how tree diversity, species identities and management (thinning and fertilization) influence both the potential of mixed forest plantations to mitigate (C sequestration) and adapt (drought and herbivory resilience) to CC, in a win-win approach. In addition, we will translate this knowledge into guidelines that can be widely adopted by practitioners and policy-makers.
MixForChange will therefore make an important contribution to promoting mixed forest plantations as nature-based solutions to fight CC.
