Predator

Technical Definition of Batesian Mimicry Sentence Definition Batesian mimicry is an ecological phenomenon in which a harmless organism copies the physical appearance of a harmful or irritating organism in order to deter predators. Origin and Use Batesian mimicry is named after the English naturalist, H.W. Bates, who discovered the phenomenon in the 1800s (The Editors of Encyclopædia Britannica, 2012). The term is used by ecologists when classifying and comparing similar looking organisms.…

Killifish (Fundulus heteroclitus) use a passive predator deterrence technique wherein, simply forming a school in the presence of predators. Research suggests that a group of active prey fish reduce the chance of being caught simply by swimming in a shoal. This may be due to the challenges a predator faces in focusing on a single prey fish and thus has reduced success of predators when hunting schools of fish. This phenomenon was deemed the predator confusion effect (Morgan & Godin, 1985;…

Evolution by natural selection and predator induced phenotypic plasticity are mechanisms that have been proposed to describe the effect of crab predation on snail shell thickness. Biologist Robin Seeley hypothesized that the periwinkle populations of New England evolved by natural selection as the European green crab was introduced to the area (Seeley, 1986). The three requirements for evolution by natural selection are that there is variation among a population, the variation is partly…

declining rapidly due to two possible problems: environmental pollution and attacks by predators. While the reading passage supports the claim that the decreasement of the sea otters is caused by the pollution, especially by human activities, the lecture points out that the assaults by the predators are the actual problem. First of all, sea otters are vurnerable to be hunted, and they have their natural predators: the orcas. It is not caused by the pollutions, contrary with the reading passage,…

representation, modelling the effects of colour mutations in “prey” and vision mutations in “predators”, and their role in natural selection. This means that different materials in this experiment represent real-life organisms and environments. The sand-coloured background represents a sand environment, while the green background represents a grass environment. The individual conducting the experiment is acting as the “predator” (bird) and the tweezers used by this individual is the beak of the…

The so called human appeared to be a predator and it turned around and threw the detective 14 ft. in the air. Every bone seemed to be intact but he was breathing heavily because he had asthma. He ran to his car, grabbed his inhaler and took his medicine. After calming down he hid behind his car and made sure his pistol was loaded. As the predator was approaching he shot 3 bullets and only one hit the predator. The bullet barely had an effect and the predator angrily knocked him unconscious. When…

Organisms across various environments develop and displays complex behaviours. Terrestrial animals, such as lions, displays evident social behaviours through the development of societies called prides (Abell et al., 2013). Similarly, fish have developed numerous social, reproductive, and predatory behaviours that allow them to adapt to various conditions. For example, observing reproductive behaviours of hermaphroditic reef fishes found that reproduction was species dependant, though there were…

to start the search for 14 missing predators in the city. Judy is assigned parking duty because the chief is doubtful of her capabilities as a bunny. Her first day on the job she's hustled by Nick Wilde and his partner. She later befriends Nick who helps her crack the case of the missing predators and restore peace…

cleverly favor both sides of the argument. This movie uses the analogy of animals of different species to represent people of different races and cultures within a given society. The different species are divided into the categories of predators and prey, with predators being the minority at 10% and prey being the majority population. Throughout the movie we see many examples of real life issues dealing with race, class, bias, stereotypes, social justice and other topics. The characters in this…

In this article, Mathew Baelor and C. O’Niel Krekorian studied the ability of the Desert Iguana (Dpisosaurus dorsalis) to detect chemical cues of predators via chemoreception. In their experiment, they used the California Kingsnake, which preys on lizards in the wild; therefore, making it an optimal predator stimulus. On the contrary, the researchers used the western shovel-nosed snake, a sympatric species to the California kingsnake, to test the general response of the iguana’s snake chemcials.…
