Concepts

Production of extracellular polymeric stalk material by diatoms when photosynthetic rates exceed cellular growth rates

The hypothesis that relationships between egg and juvenile densities are linear when egg densities are constrained below values where eggs or hatching juveniles suffer density-dependent losses

Some environments will be resource rich and produce a high amount of offspring (sources) while other environments will be resource low and produce a low amount of offspring (sinks)

Population estimation method using repeated sampling to remove individuals and estimate total abundance from decline curve

Daily patterns in organism behavior, with some mayfly species showing increased drift activity at night to minimize exposure to visual predators

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

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