Maternal leave

2004-2009

PhD student at the TU Darmstadt: “Parthenogenesis and Sexuality in Oribatid Mites”

1999-2004

Diploma thesis: “ Variability at the hsp82-locus of the parthenogenetic oribatid mite Platynothrus peltifer”

 

 

 Research interests     

 

I am interested in the ecology of oribatid mite communities in different forest microhabitats (litter, soil, dead wood, lichen, moss, tree bark) and their role as prey species in forest food-webs.
