The Passerine testing facility offers a unique oportunity to house and measure passerine birds for an array of behavioural tests in a controlled environment.

The NIOO Phytotron is a complex of greenhouses and climate chambers. In addition to offering controlled growing and rearing environments, the Phytotron offers rooms to process, prepare, harvest or store experiments. The Phytotron also provides physiological analysis- and field equipment, ovens and has a large stock of disposables which can be used.

The ecotron consists of 60 cilinders with intact (non-disturbed) sand, peat or sea clay cores (20 each). For each soil treatment, ten of the cilinders are inoculated with soil from species-rich grassland with the same soil type. The other ten are inoculated with sterile soil from the same grassland. The cilinders are buried in an experimental garden.

The sperm lab houses state-of-the-art equipment used for the analysis of sperm.This includes a computer-assisted sperm-analysis (CASA) system for accurate and automatic assessment of sperm motility and a microscope/camera/software combination for digital image analysis of sperm morphology.

The NIOO stable isotope facility is part of the chemical analytical lab, with equipment and facilities to perform stable isotope tracer experiments. Stable isotopes (13C) can be analysed in PLFA, gases (CO2/CH4) , (13C/15N) solid material (e.g. soil, plant material, bird feathers) as well as in DNA and RNA and breath samples of birds (D/H).

This is a systematic collection of eight plant species from five grassland sites in the Veluwe, for which some tissue from individual plants is stored at -80 °C. For each site, up to 10 individuals from each species have been sampled along a transect at two time points (late May and early August).

Plants and microorganisms emit a wide range of chemically diverse volatile compounds. These volatiles mediate swift chemical interactions and communication in both aquatic and terrestrial environments, and carry out important ecological functions.

This is a facility for keeping waterfowl for behavioural and physiological research. The facility consists of an outdoor aviary and a building for birds indoors.
