Jurgen van Hal
I am working as an ecological research technician at the department of Ecological science. My current tasks and skills are:
Entomology
Determination of invertebrates, incl. Collembola.
Breeding of various invertebrates
Teaching assistant 1st years course: field-entomology and lab-determination
Experimental work and field experiments
Setting up and maintaining diverse field, greenhouse and climate room experiments. These experiments include work with mesocosms, stable isotopes, plants, plant-litter, invertebrates, algae and micro-organisms.
Chemical and animal traits measurements
Diverse chemical analysis and animal-traits such as Nutrient analysis, fat-content, drought tolerance, inundation tolerance, upper thermal limit.
Molecular
DNA isolation, PCR, high-throughput sequencing and microbial community analysis.
Histology
Histology of small invertebrates
Additional skills and useful hobbies
Allround microscopy
Maintaining technical and analytical equipment.
Macro and invertebrate photography
freediving (and scubadiving)
