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.

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.

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).

Fatty acids such as Phospholipid (PLFA), neutral lipid fatty acids (NLFA) and Ergosterol (total fungal biomass) are used to assess microbial biomass and community structure in soil and other types of environmental samples. This facility provides all the equipment and knowledge required for the determination and quantification of PLFA, NLFA and Ergosterol.

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 limnotrons are nine stainless steel indoor mesocosms with a high level of control. The dimensions are: 0.97 m in diameter, depth between 1.32 m (side) and 1.37 m (centre), volume of 922 L. The vessels can be closed with a removable PMMA flange lid. In addition to the possibility of sampling vertically with specifically designed integrated water samples, sampling can also be done by using the sampling ports positioned at three depths.

Flowcytometry (FCM) is a technique that distinguishes individual particles based on light scatter and fluorescence. A large advantage is that FCM can analyse and sort cells at a very high speed of up to 10,000 cells/second.

Chemostats are bioreactors used for cultivation of phytoplankton and/or zooplankton. They can be operated as batch (no dilution rate), as chemostat (fixed dilution rate) or as turbidostats (dilution rate dependent on turbidity). They can be operated as open or closed system, and also axenically.

Since 1994, we collect genetic samples from insects (winter moth) and birds (mainly great tit, blue tit, pied flycatcher, oystercatcher and various waterfowl). The location and specifications of a sample can be found in our relational data warehouse. There are more than 170,000 blood samples, feathers and other tissues stored at NIOO. The samples can be used to investigate the genotype of an individual or population in relation to their fenotype.

The aquatic laboratories facilitate researchers working with aquatic samples, sediments or organisms. They include laboratories with specialised equipment for aquatic analyses, dedicated rooms for controlled experiments, and they give access to separate storage areas for field equipment, sample storage, chemicals and disposables stocks.
