Screening for mutants with phenotypic defects is a straightforward method for identifying genes that function in a given biological process. In this article we describe how to culture free living worms (e.g., Pristionchus pacificus) in the laboratory and show two different mutagenesis methods, EMS and TMP/UV.

A robust protocol to monitor neural populations by time-lapse video-microscopy followed by software-based post-processing is described. This method represents a powerful tool to identify biological events in a selected population during live imaging experiments.
FAQs
These stimuli can change abundance, spatial distribution, activity, or interactions, allowing researchers to compare population behavior under defined environmental conditions. Tracking measurements show whether worms concentrate in particular areas, alter movement, or display changed interactions after exposure. Comparing these patterns across conditions helps connect an environmental cue with a measurable behavioral response.
Individual movement records show how worms respond or interact, while population-level measures reveal whether those responses produce broader changes in distribution, activity, or abundance. Examining both scales helps researchers determine whether a group pattern reflects consistent individual behavior or a collective outcome. This connection supports interpretation across ecology, neuroscience, genetics, and disease-related research.
Useful measurements include worm numbers, locations, movements, spatial distribution, activity, and interactions recorded over time. Together, they provide complementary views of behavioral change rather than relying on a single observation. Repeated measurements under defined conditions make it possible to compare responses to food, temperature, chemical cues, crowding, or experimental treatments more systematically.
A single observation may capture only the worms’ state at one moment, whereas repeated observations reveal whether changes persist, develop, or reverse. Time-linked records can therefore show shifts in activity, movement, distribution, or interactions as conditions change. This temporal information strengthens interpretation of population behavior and supports reproducible comparisons between experimental groups or treatments.
Researchers first establish defined environmental conditions, then repeatedly observe or image the worms. They identify individuals or groups manually or with automated methods and record numbers, locations, movements, activity, distribution, and interactions over time. The resulting measurements can be compared across stimuli or treatments to identify population-level behavioral patterns and responses.
Tracking is appropriate when the research question concerns change over time, movement through space, population responses, or interactions among worms. It is particularly useful for examining habitat preference, social organization, development, or responses to experimental treatments. Repeated records provide a stronger basis for linking observed behavior with environmental conditions than an isolated observation.
In behavior research, the method connects measurable movement, activity, distribution, and interactions with conditions such as food, temperature, chemical cues, or crowding. The same measurements can inform studies of ecology, neuroscience, genetics, and disease-related processes. By producing reproducible behavioral data, tracking helps researchers compare population responses across experiments and experimental treatments.
