In psychology, context-dependent memory refers to improved recall of specific episodes or information when the context present at encoding and retrieval are the same. One particularly common example of context-dependence at work occurs when an individual has lost an item (e.g. lost car keys) in an unknown location.
In population ecology, density-dependent processes occur when population growth rates are regulated by the density of a population. Most density-dependent factors, which are biological in nature (biotic), include predation, inter- and intraspecific competition, accumulation of waste, and diseases such as those caused by parasites. Usually, the denser a population is, the greater its mortality rate.
