Katja Wehner

Dr. Katja Wehner is a Postdoctoral Researcher in the Faculty of Biology at the Technical University of Darmstadt, Germany, specializing in soil arthropod ecology with a focus on oribatid mite communities across forest microhabitats including litter, soil, dead wood, and tree bark. Her work examines their role in forest food webs and responses to environmental stressors.

Education:

• PhD in Biology, Technical University of Darmstadt (2009). Dissertation: 'Parthenogenesis and Sexuality in Oribatid Mites'
• Diploma in Biology, Technical University of Darmstadt (2004). Thesis: 'Variability at the hsp82-locus of the parthenogenetic oribatid mite Platynothrus peltifer'

Research Focus: Dr. Wehner investigates biotic interactions and acarological dynamics in Central European forests, emphasizing how land-use intensity, drought, and structural factors shape oribatid mite biodiversity. Her work integrates community ecology, soil science, and microhabitat specialization to understand ecosystem resilience and food-web interactions, with particular attention to parthenogenetic versus sexual reproduction strategies in microarthropods.

Publication Trends: Recent publications (2018-2022) reveal a strong emphasis on anthropogenic impacts, including land-use change effects on aboveground-belowground linkages, drought/storm damage consequences for soil communities, and microhabitat-driven variations in mite sex ratios and seasonal dynamics. Her collaborative work in journals like Nature Communications and Global Ecology and Conservation demonstrates methodological integration of field surveys, controlled experiments, and multi-taxon analyses.

Collaborative Networks: Dr. Wehner actively participates in large-scale ecological initiatives including the Biodiversity Exploratories project, collaborating with researchers from institutions like the Technical University of Munich and University of Würzburg on cross-taxa biodiversity studies. Her co-authorship on multi-investigator papers indicates strong engagement with Germany's ecological research infrastructure.
