Concepts

Percentage of nest area hidden from predators when viewed from directly above, measured using gridded circle

When animals prefer to associate with certain individuals over others within a group

The number of weeks during a growing season when both pollinators and their floral resources are active and available

Sampling method using buried containers with killing solution to capture ground-dwelling invertebrates

Standardized method for observing and counting birds at fixed locations for specified time periods

Method of covering flowers with mesh bags to prevent pollinator access and allow nectar accumulation for sampling

The rate at which predators consume prey, measured as prey mortality per predator per unit time

Spatial intersection of radar beams from different systems enabling measurement comparison

The ability to maintain fitness after damage, measured through both genetic and environmental components of tolerance including resource acquisition and storage traits, and traits involved in pollinat...

The production of reproductives (males and new queens) by bumble bee colonies, measured as abundance of males in late season

Classification of female reproductive phase as gestation/lactation or post-reproductive/pre-hibernation

Successful production of larvae that develop to feeding stage on buried carcasses

The body size of mayflies when they emerge as adults from aquatic larval stage

Measures the proportion of relationships within a group where both individuals initiate interactions with each other, indicating mutual social relationships

Distinct layers in soil profile with different physical and chemical properties

The difference between observed streamflow and expected or baseline streamflow, representing water shortage

Use of 87Sr/86Sr ratios to trace sources of nutrients and water in ecological systems

Statistical methods for analyzing time-to-event data, here focused on summer survival probability

The rate at which temperature decreases with elevation, typically expressed as degrees Celsius per kilometer

Linear distance along stream between upper and lower boundaries of breeding territory

Behavioral activity of birds when captured in traps, measured as activity index from feeding to high distress behaviors

The physical arrangement and composition of vegetation including coverage of different plant types, heights, and density
