A hunting and gathering subsistence pattern in which there is not a concentration of efforts in harvesting a small number of species. Rather, virtually all potential food sources in the environment are exploited. Most pedestrian foragers take a diversified approach. In contrast, aquatic and equestrian foragers are specialized. A diversified subsistence pattern has the advantage of relative economic security if there are fluctuations in the weather, water supply, or periodic die-offs of the food sources. The disadvantage is that the total amount of food calories acquired is often less and the amount of time required to secure them is greater compared to specialized foraging.
