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.

The innate immune response protects organisms against pathogen infection. A critical component of the innate immune response, the phagocyte respiratory burst, generates reactive oxygen species that kill invading microorganisms. We describe a respiratory burst assay that quantifies reactive oxygen species produced when the innate immune response is chemically induced.

Certain organic substances change color in dilute solution when the hydronium ion concentration reaches a particular value. For example, phenolphthalein is a colorless substance in any aqueous solution with a hydronium ion concentration greater than 5.0 × 10−9 M (pH < 8.3). In more basic solutions where the hydronium ion concentration is less than 5.0 × 10−9 M (pH > 8.3), it is red or pink. Substances such as phenolphthalein, which can be used to determine the pH of a solution, are called...

Repeated soil sampling has recently been shown to be an effective way to monitor forest soil change over years and decades. To support its use, a protocol is presented that synthesizes the latest information on soil resampling methods to aid in the design and implementation of successful soil monitoring programs.
FAQs
Interpretation becomes more reliable when physical, chemical, and biological measurements are considered together. A soil may show a favorable value for one property while other measurements reveal limitations in water movement, nutrient cycling, or biological activity. A combined indicator set therefore reduces the risk of drawing broad conclusions from a single aspect of soil function.
These measurements address related but distinct aspects of soil processes. Soil organic carbon contributes information about the soil’s carbon condition, whereas microbial respiration reflects activity associated with decomposition. Examining both can help researchers connect a measured property with an active biological process, strengthening interpretation of nutrient transformation and overall soil functioning.
pH, aggregate stability, and water infiltration cover different dimensions of soil performance. pH supplies a chemical measurement, while aggregate stability provides evidence about soil structure and infiltration indicates how water moves into the soil. Reading them together helps environmental researchers distinguish chemical conditions from structural or water-related limitations when evaluating soil function.
Researchers can use multiple indicators to represent different dimensions of soil function, measure those properties in soils under different management practices, and compare the resulting patterns. This approach can reveal changes in carbon, chemical conditions, structure, water infiltration, or biological activity, supporting evidence-based decisions instead of relying on one measurement.
Indicators provide a basis for tracking change during environmental monitoring or management periods. Patterns involving soil organic carbon, aggregate stability, infiltration, pH, or microbial respiration can be examined as evidence of altered soil function. Using several measures helps researchers evaluate whether changes reflect broader degradation or recovery rather than a shift confined to one property.
During land restoration, these measurements help researchers assess whether soil function is recovering and guide conservation decisions. Results can be related to the soil’s capacity to support plant growth, regulate water, cycle nutrients, and sustain living organisms. This connects restoration monitoring with resilient ecosystem goals and provides evidence for evaluating progress across multiple aspects of soil performance.
