WebMar 22, 2014 · A series of optimal foraging theories have been developed in line with this objective [ 3 ]. By assuming that animal activities are optimized to maximize the rate of net energy gain, optimal foraging theories provide testable hypotheses as well as bases for interpreting complex animal behaviour [ 3, 4 ]. WebOptimal foraging theory uses predators as the object of analysis. There are four functional classes of predators: True predators attack large numbers of their prey throughout their life. They kill their prey immediately, or shortly after the attack. They may eat all …

WebCase study 1—foraging. Foraging behavior is a series of actions that predators take to hunt for food and it includes searching, chasing, catching, processing, and ingesting. It is an excellent indicator for evaluating individual performance as marine organisms need food to supply vital energy for basic life functions.
WebThis is the crux of the optimal foraging theory, the optimality model that predicts animal behavior based upon the balance of acquiring food and spending energy in the process. WebAbstract. Optimal Foraging Theory (OFT) uses techniques of mathematical optimization to make predictions about foraging behavior which is a fundamental aspect of animal behavior. As it has just turned 50, it is timely to review its foundations, what it has achieved and where it is headed. As an introduction to OFT, I discuss the classic model ...
Web生态生产力（英語： ecological productivity ）是指生态系统中生物质的产生速率，通常以单位时间、单位体积（面积）的质量表示，例如克每平方米每天（gm-2 d-1 ）。 质量单位可能与干物质或生成碳的质量有关。 植物等自养生物的生产力称为初级生产力，而动物等異營生物的生产力称为次级生产力。

Like all optimal foraging models, the optimal diet model has a mathematical description: E is the amount of energy a prey item provides; h is the time it takes for a predator to consume the prey, the search and handling time. The profitability of a prey item is therefore defined as E / h. bitchet farm
