Predation

to make it clearer. Bates uses the term “fable” which suggests three variables in order to determine the true reason and explain the process. Africa is rich for resources like oil and precious minerals. Access to great source of wealth showed predation of “specialist in violence”, the term, which he uses to describe the rulers. Military leaders became heads of their states and recognized richness of their states for natural resources. Unexpected wealth made them to act as predators. Another…

Recruitment of Organisms in the Galveston Ship Channel Abstract A study was done in the Galveston Ship Channel to see the recruitment of sessile or fouling organisms to a substrate. A total of six organisms were found. They were Barnacles, Serpulid Worms, Bryozoan, Limpets, Tunicates, and Amphipods. Recruitment structures were created by the students and were put into the Galveston Ship Channel and left for five weeks to allow adequate time for organisms to adhere to it. A full mesh cage was…

Marion Petrie began her controlled breeding experiment with peacock offspring by observing peahen mate preferences in Whipsnade Park, UK. Observations showed that peahens appeared to have a preference for peacocks with more elaborate trains (i.e. larger in size and more eyespots). Petrie was interested in finding out why the peahens were mostly attracted to the peacocks with the most elaborate trains in this population. To test this idea, Petrie took eight males of different attractiveness from…

"job" in that environment, what an organism eats, and how it interacts with other biological and non-living species. There must be a symbiotic relationship between all species. The three main niches an organism might contend with are commensalism, predation and mutualism. Ecology is about how the species of an ecosystem interact together, their interaction with their environment, and with each other. Plants and animals interactions one must think about are mutual beneficial ones known as…

diminished after the extirpation of the wolves. With the wolves gone, ungulate populations were allowed to grow to problematic levels and affect plant growth (Ripple 2014). When the wolves were reintroduced, elk browsing decreased, either due to the predation of elk or the behavioral responses of elk avoiding areas where wolves were present (Ripple 2014). Fortin et al. conducted a study to explain the mechanics of how wolves affect net primary production not only by preying upon the elk, but…

Grizzly bears feed on ungulates primarily as winter-killed and wolf-killed carrion but also through predation on elk calves (Gunther and Renkin 1990, Mattson 1997). Some large male grizzly bears also prey on adult bison during early spring. Grizzly bears also dig up pocket gopher caches in localized areas where they are abundant. Other items consumed during…

quality rather than of a lower quality. 2.) Ants are sensitive to foraging gains and predation risks. Predictions 1.) Ants will prefer to forage for sugar water that is highly concentrated rather than water that is less concentrated. 2.) Ants will prefer to forage close to their home net site rather than farther away from their home nest site. 3.) Ants will balance the trade-off between the risk of predation and food quality. Ants will take greater risks for high quality food than they will…

This is due to the fact that it has been affected by predation and parasitism for so many years but still hasn’t developed any manner of defending itself from it’s predators. The fact that after all these years there still hasn’t been any sort of behavioral adaptation that would increase their reproductive…

Mud flats are a vital type of marine habitat that provide several different functions for various marine invertebrates. They provide both permanent and temporary homes to small invertebrates including several species of worms, crabs, snails, and other benthic fauna. These organisms are responsible for the breakdown of organic materials often deposited here, as well as filling the role of prey for many predators that hunt in the shallow waters (Dyer et al., 2000). Mud flats are most often…
