Foraging

defenseless against competitors and the inability to find food more readily. This is often seen in field crickets (Gryllidae), which frequently show aggressive behavior when hungry which makes them ideal specimen to observe different factors of foraging and competitive behaviors (Dixon and Cade 1986; Brown et al., 2007). In A. domesticus, male fighting ability has been related to size, territory, food resource, and its energy cost (Nosil, 2002; Hack, 1997). However, these studies only observed…

lives of people in skid row and those apart of the well-known community, the Ju/’hoansi. Although each society is a part of a different environment, skid row being urban and Ju/’hoansi being rural, it is remarkable how they are related through common foraging methods. In comparison, the purpose of exchange practices of the Ju/’hoansi’s hxaro system and the process of exchange on skid row are the similar, yet each society performs the exchange with different types of people.…

Hunting in packs also is more successful than hunting alone since it increases the chances of catching the prey (Baenninger 1978). Group hunting allows many predators a unique opportunity to combine optimal foraging, group decision-making and athletic ability in successfully attaining their prey (Bailey et. al. 2012). In the context of hunting, cooperation can simply mean two or more individuals (related or not) increasing their fitness (success and, therefore…

As a whole, foraging societies provided more gender equality between men and women then settled cultures, although the daily chores for survival were usually still divided into men’s tasks and women’s tasks. One of the reasons foraging societies were inclined toward this egalitarianism was because they did not view leadership as a position of permanence or power, instead…

While near pinniped rookeries in autumn and winter, sharks avoid the surface and use water to 50 meters in depth which is consistent with a silhouette-based hunting strategy. White sharks also exhibit a broad depth distribution offshore and remain there for the spring and summer (4). White Sharks typically spend their day in temperatures between 15C to 24C (59F to 75F). However, as they begin to hunt their prey, they dive down deep into the ocean and slowly rise as they look for food. Sharks…

Wealth inequality is not the only form of inequality that arose due to the advent of farming. Gender inequality is another form of inequality that has been a major aspect of society ever since humans began to farm (The Guardian). Hunter-gathering humans were very egalitarian in regard to the role of women in their societies (Ibid.). Studies have shown that women in hunter-gathering societies had equal influence in group decisions in regard to where the group lives and with whom they live (Ibid.)…

predator avoidance; therefore, modulating the level of risk with environmental factors should influence the expression of anti-predator behaviors. Based upon this idea, the research team predicted that chipmunks should be more vigilant when they are foraging in open habitats and high wind intensity. Additionally, the researchers expected for vigilance to increase if alarm calls were heard, and when living under a high level of neighbor density.…

ant systems, has been quite successful in finding the salesman's optimal path. Its success can be attributed to the fact that swarm intelligence excels in combinatorial optimization problems. Locating the optimal path mirrors the process of ants foraging for food. In both cases, ants are dispersed randomly in search of the nearest city. The ant that returns first communicates its findings to the colony. This communication attracts other ants and "directly reinforces good solution”. Information…

also take larger particles. Therefore, when predation is of low intensity the small planktonic herbivores will be competitively eliminated by large form. This is considered a classic ecological paper because it lays the foundation for the optimal foraging…

Science Paper Marine biologists study the behaviors of all marine organisms. They also have a lot of knowledge on all marine organisms. However, everything there is to know about the carnivorous great white sharks’ species hasn’t been discovered yet. Scientists can only do so much with these organisms in a controlled environment (or captivity) before an incident occurs where the shark either dies or puts others in danger. Erik Vance’s article, “Why Great White Sharks Are Still a Mystery to Us”…
