The Optimal Foraging Theory Abstract.Ý The theory of optimal foraging and its relation to central foraging was examined by using the beaver as a modelÝ (summarizes the Introduction). Beaver food choice was examined by noting the species of woody vegetation, status (chewed vs. not-chewed), distance from the water, and circumference of trees near a beaver pond in North Carolina (summarizes the Methods).Ý Beavers avoided certain species of trees and preferred trees that were close to the
of pottery and before hunter-gather societies settled into villages. The variety of crops from agriculture result independently before spreading later to the American Southwest and the Northern America during the Formative period. The optimal foraging theory could explain the role of human actions in spreading of agriculture as a by-product of rational societies adapting from the Mesoamerican example for self-interest of reproducing valuable food sources. This belief was easily spread through
Hypotheses of the Effects of Wolf Predation Abstract: This paper discusses four hypotheses to explain the effects of wolf predation on prey populations of large ungulates. The four proposed hypotheses examined are the predation limiting hypothesis, the predation regulating hypothesis, the predator pit hypothesis, and the stable limit cycle hypothesis. There is much research literature that discusses how these hypotheses can be used to interpret various data sets obtained from field studies
could forage in like manner. An equal number of students took long and short routes to the foraging patch and collected simulated food items in a way that simulated diminishing marginal returns. Data on travel time, foraging time, and number of food items collected were collected. The data differed significantly from the calculated optimal values. This may be a result of low number of trips between the foraging patch and the simulated dwelling. Introduction When animals forage, many factors become
Optimal Foraging Theory: States that food seeking behaviors of many animals maximize the nutrition gained in relation to the energy expended to locate, secure, and consume various food.

In this lab, we explore the theory of optimal foraging and the theory of central place foraging using beavers as the model animal. Foraging refers to the mammalian behavior associated with searching for food. The optimal foraging theory assumes that animals feed in a way that maximizes their net rate of energy intake per unit time (Pyke et al. 1977). An animal may either maximize its daily energy intake (energy maximizer) or minimize the time spent feeding (time minimizer) in order to meet minimum
assumption that there is no predation or competition, which are additional factors that will influence behavior. Fish bioenergetics includes components of physical forces, thermodynamics, and light characteristics, and follows energy laws and theories describing any other closed system. What it all boils down to is the net rate of energy intake. If this rate is positive a fish will grow and if it is negative then a fish will begin to undergo the stresses of losing biomass. Fish bioenergetics
Methodological summary Mittelbach (1988) wanted to know whether the pressure of predation can cause pressures of competition. A body of literature describing a “landscape of fear” shows that prey species alter their behaviour in response to perceived predation risk, often avoiding those areas that may increase chance of predation and preferring ones that offer escape routes. Prey species seeking to escape predation risk will hide in shared refugia, which offer both protection and food resources
influence for use and artificial behaviour is seen as insincere. Intelligence is defined as the ability to gather, understand and then appropriately use the information and further broaden knowledge. Artificial intelligence together is identified as a ‘theory’ in which computers or machines are able to perform tasks normally undertaken requiring human intelligence. Visual perception, recognition of speech, language translation and decision-making are certain tasks that can be completed. 2. SWARM INTELLIGENCE
from the ice age evaporated. The way in which the first inhabitants arrived here is in dispute today more than ever. By examining the mystery of the Bering Straight Land Bridge, The history and religion of some key Native American Tribes and the theories of prominent modern day scientists I hope to shed some light of the mystery of the origins of the first peoples of America. The Bering Straight Land Bride or BERINGIA is believed to be a strip of permafrost that connected Alaska to Asia around
