A BSR is likely to manifest as both an increased spectrum of food resources and an evenness in the exploitation of high- and low-value prey. Under a broad spectrum economy a greater amount of low-value prey (i.e. high cost-to-benefit ratio) would be included because there are insufficient high-value prey to reliably satisfy a population's needs.
Pygmy hunter-gatherers in the Congo Basin in August 2014. A hunter-gatherer or forager is a human living in a community, or according to an ancestrally derived lifestyle, in which most or all food is obtained by foraging, [1] [2] that is, by gathering food from local naturally occurring sources, especially wild edible plants but also insects, fungi, honey, bird eggs, or anything safe to eat ...

A new source of sustenance has been added to the California diet. Wildlife agencies are urging locals to eat an invasive rodent wreaking havoc on the surrounding ecosystem. “EAT ME!
In fact, we see that lion foraging behavior does not maximize their energy gain. They are not behaving optimally with respect to foraging because they have to defend their territory and protect young so they hunt in small groups to reduce the risk of being caught alone. [33] Another factor that may influence group size is the cost of hunting.
One classical version of the optimal foraging theory is the optimal diet model, which is also known as the prey choice model or the contingency model. In this model, the predator encounters different prey items and decides whether to eat what it has or search for a more profitable prey item.
