Introduction
Ants are excellent at finding new sources of food. They have to be in order to find enough food to feed the whole colony. Worker ants randomly explore a new site until they find something that can be consumed (Deneubourg 1990). A chemical trail is then laid down by the pioneer ant to recruit other ants from the nest to the site of the food (Deneubourg 1990). There are three types of recruitment: tandem recruitment, mass recruitment and group recruitment (Beckers et al. 1989). Both mass and group recruitment uses chemical trails to lead nest mates to food items(Beckers et al. 1989). Chemical trails allow the colony to remember where rewarding food sources are, to choose between locations of different food qualities and even to regulate total foraging activity (Jackson & Ratnieks 2006). The objective of this study was to determine food preference and recruitment time in garden ants. How quickly do ants find rewarding food sources, how long it takes them to recruit more ants and which food sources they prefer?
Materials and Methods
Two experiments were conducted, one using different tasting solutions and one using peanut butter. The peanut butter experiment was done fist so as to recruit ants for the next experiment. 3 petri dishes with peanut butter on slices of bread were placed at 20, 40 and 60 cm’s from an ant nest. The time of discovery, recruitment time and number of ants at each dish was then recorded. The experiment was then repeated. Next, 4 marked petri dishes with bread were placed at equal distances from the ant nest. Sweet, sour, salty and water (control) solutions were separately placed on the pieces of bread with droppers. The amount of ants attracted to each dish was then recorded over a 5 min period. T...

We observed Sowbugs in multiple environments to determine which environment they preferred. The observational chamber was a rectangle box split equally in half. One side of this rectangle was filled with dry sand that had been heated for five minutes by a lamp, and the other side was filled with damp soil that did not receive the lamp heat. We placed each sowbug on the middle boarder of the cool, damp soil and the hot, dry sand. We each chose one sowbug to track, and made a record of its placement each minute for five minutes total. We repeated this process three times. After each repetition, we removed the sowbugs, and replaced them with new sowbugs to observe. After this observation, we shared, and recorded our results. The sowbugs spent

Organisms such as starlings and honeybees appear to forage based on the marginal value theorem. This experiment tested whether humans 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.

The titmouse is a small songbird that searches acrobatically for insects among foliage and branches. The tufted titmouse, also known by their scientific name of baeolophus bicolor, is a widespread species from North America. Because the species is so widespread, it can be assumed that the species is not limited by the biotic and abiotic factors that other species are limited by. The titmouse eats only insects in the summer, including caterpillars, beetles, ants, wasps, stink bugs, and treehoppers; they also eat seeds, nut, and berries. However, every population, or a group of individuals of a single species living in the same general areas, is limited by a carrying capacity, or the maximum population size that a particular environment can sustain. At one point, the biotic or abiotic factors will limit the dispersion and dispersal of the

Elizabeth Cashdan addresses the question of territoriality among human forager groups, specifically comparing four Bushman groups. She argues that territoriality should occur only in places where the benefits will outweigh the costs. Introducing the scientific definition of territoriality in animals, she first claims that animals tend to be the most territorial when they have adequate food and other resources. It is when there is a severe lack of or abundance of resources that animals are not territorial. With a lack of food, territoriality tends to waste too much energy. In the case of an abundance of food, it is not worth defending that which is plentiful for animals. She points out predictability as another environmental factor: if a resource is unpredictable, then it is not economical to defend it. It is only worthwhile to defend a territory if there is high probability that the resources will still be available when they are wanted. However, the costs and benefits of being territorial not only depend on the environment, but also on the species and its characteristics.

Most ants live together in large groups called colonies. Colonies are highly organized societies. They can consist of hundreds, thousands, and even millions of ants. The ants in a colony work together to choose the site of their nest.
honeybee’s means of communication there was no change in the number or diversity of the pollen types that each colony collected each day(Donalson, et al, 2013). The group originally hypothesized that communication would focus all or the majority of the colonies foraging efforts on a highly productive natural pollen resource. Instead, the group found that impairing dance communication resulted in the honeybees returning with rare novel pollen types instead of foraging on the same pollen resource types from day to day( Donalson, et al, 2013). The authors suggest that the communication dance enables colonies to maintain their foraging efforts on previously discovered rewarding pollen resources, while exploring fewer newer sources each day (Donalson, et al, 2013). The honeybee communication dance is
The experiment was conducted to test three different variables. These variables are an assessment of female aggressiveness, food deprivation, and staged male to female interactions. When testing the female aggressiveness, virgin females were run through a latency of attack assay to determine their aggressiveness. The spiders were given 30 seconds and a cricket was dropped in and a measurement was taken of how long interaction occurred between the cricket and the spider. When testing food deprivation, the number of days that female spiders went without food varied and was paired in groups of 1, 3, and 5 days for routine feeding. It was predicted that the longer female spiders went without food, the hungrier they would be. When testing staged male and female interactions, the males were placed in female containers with open lids as an escape route. Each pair interacted for six hours and all pairs resulted in successful copulation, sexual cannibalism, or the male abandons the female’s web. All instances of cannibalism were precopula and occurred shortly after males initiated their courtship sequence. After interaction, the remaining males were taken out the female web and females that cannibalized a male were given 24 hours to feed on the male before being given another male. A female never cannibalized two males consecutively. It was concluded that females that attacked prey more rapidly were more likely to cannibalize their first male mate. There is no detection of an association between cannibalism or food deprivation and female’s body mass. There is a positive association between the mass of egg cases and the number of offspring in females. The study proved that two factor are important in sexual cannibalism, female hunger state and female aggressiveness. There is also a source of fitness benefit for the female.
The way an animal behaves is immensely influenced by its surrounding environment. The process by which an animal acquires its food in its habitat can be affected by several elements, both biotic and abiotic. When foraging, it is essential that animals consider food selection and availability, risks of predation, and competition with other animals for the same food source. Among the diversity of factors upon which foraging decisions are made is the risk of predation and habitat structure. According to Powell and Banks (2004) predator odors along with habitat structure are thought to influence the behaviour of small mammalian prey, which use them as cues to reduce risks of predation.
Myrmecology has been around since the late 18th and early 19th century. Myrmecology is derived from the Greek word Murmek, which means ant. There are three main names that are most noteworthy: Linne who produced “Systemae Naturae” which he describes eighteen species of ants. Fabricius created five more genera and further described other species. Latreille was the most significant, he collected and studied the ants of Europe and described many species overlooked by his predecessors. In 1967 a fossil was found that was preserved in amber fossil which showed an extinct species of an ant dating as far back as the Cretaceous Age, near eighty million years ago (as cited in Ant Nest, 2005).
Seventh, in some groups of insects, truly social behavior has evolved. Social behavior will allow a large population to survive through difficult periods via cooperation in food gathering, food storage, temperature control, and colony
