We demonstrate the utility of nest building behavior in laboratory mice as an indicator of welfare. Nest scoring is a sensitive technique that is altered by temperature, illness, and aggression. The time to integrate into nest test (TINT) is a simple cage-side assessment that can detect postoperative pain.

Burrowing, nesting, and hoarding are species-typical activities that mice readily perform in the laboratory. This article describes how they can be easily and cheaply assessed. These protocols are extremely sensitive to mouse strain, brain lesions and diseases. Moreover they constitute “environmental enrichment” for the mice, and embody the “Refinement” aspect of the “3 Rs”18.

Nested-PCR to Detect a Specific Viral Genomic Sequence

This video describes nested polymerase chain reaction, a technique that consists of two sequential PCR amplification processes using two primer sets. The first set of primers is intended to anneal to sequences upstream of the second set, resulting in selective amplification of specific gene sequences. This PCR is more sensitive and specific than a normal PCR and is widely used as a detection technique for various diseases.

Preventing colonization of bird nest boxes by invasive Africanized honey bees is important for conservation efforts of nest-site limited birds. We provide an integrated pest management approach to "push" bees away from nest boxes with a repellant insecticide, permethrin, and "pull" them toward pheromone baited swarm traps.

Introduction to z Scores

A z score (or standardized value) is measured in units of the standard deviation. It tells you how many standard deviations the value x is above (to the right of) or below (to the left of) the mean, μ. Values of x that are larger than the mean have positive z scores, and values of x that are smaller than the mean have negative z scores. If x equals the mean, then x has a zero z score. It is important to note that the mean of the z scores is zero, and the standard deviation is one. z scores help...
FAQs
Nest quality scores are most informative when interpreted as a composite behavioral outcome rather than a direct readout of one brain function. Poor performance may reflect reduced motivation, impaired motor ability, cognitive disruption, or an altered affective state. Consequently, the score can show that behavior has changed without, by itself, identifying which neural process caused the change.
These features represent distinct observable aspects of nest construction and maintenance. Material use indicates how the provided resource is handled, while structure, enclosure, and organization describe the resulting arrangement. Applying defined criteria to these features makes the assessment more systematic and helps researchers compare behavioral changes across animals or experimental conditions.
Standardized nesting materials and observation conditions create a common basis for evaluating behavior. They reduce variation in the resources or setting available to the rodents, allowing differences in material use, structure, enclosure, and organization to be considered in relation to the experimental condition. This supports clearer comparisons when studying disease-related behavior or intervention responses.
A basic workflow begins by providing standardized nesting material under defined observation conditions. After the rodents have had an opportunity to construct and maintain a nest, the evaluator examines material use, structure, enclosure, and overall organization. The observed features are then matched to established scoring criteria to produce a standardized behavioral outcome.
The assessment depends on standardized nesting materials, an appropriate rodent enclosure, and controlled observation conditions. The material gives the animal an opportunity to construct a nest, while the enclosure contains the resulting structure for evaluation. Keeping these elements defined is important because the score is based on observable construction and maintenance features.
In neuroscience, researchers can apply the assay to models of neurodegeneration, brain injury, and psychiatric disorders. Reduced nest quality may provide evidence of altered motivation, motor function, cognition, or affective state in these models. Because the outcome is relatively simple and low-cost, it can also support evaluation of behavioral responses to experimental interventions.
