Project description
Global climate change and pollution are major threats to ecosystem integrity and biodiversity, and challenge a sustainable future. Climate change affects the accumulation and effects of pollutants in organisms, so-called climate-induced toxicant sensitivity. In the SoilStress project funded by the Research Council of Norway (project number 358314), we address mechanisms underlying cumulative effects, recovery, and ecophysiological tipping points from multiple stressor disturbances (climate change and pollution). We will study complex questions of WHY key biological responses to multiple stressors (climatic stress and agricultural used pesticides) differ between populations, micro-climate, and climatic regions; WHY tolerance to pesticide exposure decreases with temperature stress; and IF the tipping point to disturbance by temperature and pesticides, and recovery from disturbance removal, depends on the populations phenotypic plasticity and/or genetic adaptation. As our model system, we study springtails (Collembola), key terrestrial ectothermic invertebrates of the soil community.
The postdoc will be mainly responsible for conducting long-term laboratory experiments investigating why pesticides exhibit increased toxicity to springtails at higher temperatures, exploring mechanisms such as enhanced bioaccumulation leading to elevated internal concentrations, metabolic scaling effects, and the rising costs of repair and homeostasis maintenance under pesticide-induced stress. This involves analyzing toxicokinetic processes in the ecologically relevant species Hypogastrura viatica and its diet across varying temperatures and exposure concentrations, while considering how temperature influences uptake, elimination, biotransformation, and the formation of potentially more toxic metabolites. The role emphasizes sublethal effects on fitness, using demographic modeling to assess impacts from genes to populations, and testing hypotheses related to metabolic rate increases, energy allocation shifts, temperature-dependent bioaccumulation, and varying toxicity across biological levels.
We seek a highly motivated, enthusiastic candidate who has completed a PhD degree (or other corresponding education equivalent to a Norwegian doctoral degree) in ecotoxicology or related fields. Candidates with experience in experiments with soil invertebrates, especially springtails, and publishing papers in leading journals are highly encouraged to apply.
The main purpose of a postdoctoral fellowship is to provide the candidates with enhanced skills to pursue a scientific top position within or beyond academia. To promote a strategic career path, all postdoctoral research fellows are required to submit a professional development plan no later than one month after commencement of the postdoctoral period.
What skills are important in this role?
The Faculty of Mathematics and Natural Sciences has a strategic ambition to be among Europe’s leading communities for research, education and innovation. Candidates for these fellowships will be selected in accordance with this, and expected to be in the upper segment of their class with respect to academic credentials.
Required qualificatios:
- Only applicants with an approved doctoral thesis and public defence at are eligible for appointment. The degree must be equivalent to a Norwegian doctoral degree in ecotoxicology, ecology, or related fields
- Demonstrated experience and ability to conduct ecotoxicological, ecological or physiological experiments targeting sublethal effects in animals
- Demonstrated experience in toxicokinetic and toxicodynamic studies
- Proven skills in statistical analysis
- Fluent oral and written communication skills in English or a Scandinavian language
Desired qualifications:
- Driver license Level B
- Proficiency in statistical analysis to evaluate sublethal effects, preferentially under combined stressors exposure like temperature and pesticides
- Experience with bioinformatics (omics interpretation).
- Experienced in working with soil invertebrates, particularly springtails
- Familiarity with life history theory and energy allocation issue
All candidates and projects will have to undergo a check versus national export, sanctions and security regulations. Candidates may be excluded based on these checks. Primary checkpoints are the Export Control regulation, the Sanctions regulation, and the national security regulation.
