Counting and determinations of species from field studies

Based on many years of experience and our broad taxonomic expertise, we offer determination, counting and analyses of animal groups from field studies

Species counting and determination

Due to our high taxonomic expertise for different animal groups and the possibility to work under GLP in our laboratories, we offer counting and determinations for field studies on a high standardised level. Our expertise ranges from precise taxonomic species knowledge of predatory arthropods (spiders, ground beetles) to flying insects (hoverflies, butterflies) to endogeic ground animal groups (collembola, mites, lumbricids). Other groups are worked on at different taxonomic levels as required.

Extraction of soil organisms

Soil organisms living in the soil are normally extracted from the soil by heat gradient extraction. Gaiac has a so-called McFadyen extractor available for this purpose.

Sampling, soil cores and soil traps

We would be pleased to support you in planning and carrying out your field trials. We can install soil traps, take soil core samples and record flying insects.

Statistical analyses

Data sets from field studies are complex and require careful evaluation. We have many years of experience in the statistical evaluation and assessment of field study results. We would be pleased to support and advise you in the implementation of field studies from planning to completion.
