Biological Basis Of Behavior : The Great Grey Owls ( Strix Nebulosa )

The purpose of our experiment is to test animal behavior and reactions to a change in environment. Our guiding question is, “Why do living organisms respond to environmental factors?” This is basically a question that is asking why living things will react a certain way to environmental changes. The task to answer this question is to experiment with changing environmental factors with pill bugs.

In Sven Birkerts writing, “The Owl Has Flown,” Birkerts puts forth something to think about for any modern day reader. Birkerts believes that over the years the methodology of reading has changed as the technology has advanced. In the older days, people had small amounts of texts to choose from, but read them more thoroughly, and gained in depth knowledge about each book. In this day and age, the scope of reading has broadened but at the same time become shallower. He believes that we now read large amounts of materials, divulging ourselves into all sorts of different subject matter, but that we merely skim across its surface gaining no knowledge. In his opinion we have gone from vertical to horizontal depth. He deems an increase in the

Ans-A- The biological constitution of a living organism has a mammoth influence on the sense perception of an organism. The biological institution of an organism can even enhance or degrade the level, degree and method of sense perception by an organism. Take the Homo sapiens or rather humans for example the relatively strong eyesight causes the overdependence on eyesight and eyes and the other senses are therefore held in less importance and

Barred owls are large, stocky owls with rounded heads, no ears tuffs, and medium length rounded tails. Barred owls live in large, mature forests near water. Spotted owls are dark-brown, large owls with rounded heads, the wings are broad and rounded, and the tail is short. Spotted owls also live in mature, large forests but, are sensitive to habitat disturbance. Now, Barred owls and Spotted owls are in a intense war for homes.

Paragraph 3. Adaptation and Survival

Soaring high above the ground late at night, under the dark canopy of trees. Stooping down low to catch a small rodent. It flies back up into its nest, ready to eat. There is only one animal that matches all of these descriptions, and that’s an owl! A particular owl, called the Northern Spotted Owl, is a small brown bird that lives in old-growth forests also known as “cloud forests”. This essay will provide information on the northern spotted owl and discuss its appearance, habitat and diet, and give you some interesting facts about it.

The animals have to defend themselves since there are so many species. Some animals adapt by using their body parts. One of the animals there are echidnas. They mainly use their spines “as a defense mechanism.” The long hairs on the echidnas are used as their spines and are made out of the same material as fingernails. Many animals have to survive different ways, such as wombats. They are “nocturnal animals.” The wombats sleep all day and at night they go out to hunt for food.

In biology, adaptation is the process by which an organism changesto become better suited to survive in their environment. It canalso refer to a physical or genetic trait that helps an organism tobe better suited to survive in their environment. For example, polar bears are adapted to living in the cold becausethey grow thick fur that keeps them warm, and thus allows them tosurvive in their frigid environment. The color of their fur is alsoan adaptation. Because the environment they live in is mostlywhite, they have produced white fur to blend in, so they are notseen by the prey they hunt. Adaptation is powered by natural selection. When a trait arisesthat allows an organism to better adapt to their environment, itwill be passed on to the next

Non-historical definitions of adaptations are more useful for modern interpretations of adaptations. Gould and Vrba’s hypothesis finally addressed the origin of the adapation and claimed “an adaptation was a trait whose “historical genesis” was due to the same selective pressure as that which currently maintains the trait.” An adaptation which no longer had a selective pressure was named an

In the beautiful nature, the animals and human have demonstrated the variety of their wonderful abilities. The adaptation is one of ability that can be implied as a process of nature that all systems of the body synchronized movements for inducement the body appropriate to the natural habitat, situation, and condition. The adaptation of animals is controlled by internal neural systems [81] and presented in the several forms of deportment. For example, upgrades and downgrades in relationships, shifts in function, or changes in habitat.

This is why there are several different types of behaviours used to describe these specialized survival instincts. One of these would be orientation responses that are divided into two classes called taxes and kinesis. The animal behaviour that is being investigated is taxes. Taxes are the directional movement that is made by the animal in response to a stimulus. The types of stimulus would be food, sound and light etc. “Different taxes (plural of taxis) result in response to different types of stimuli. Each of these forms of taxis can be described by simply adding a prefix to the word taxis. The table below shows the most common forms of taxis (SparkNotes, n.d.)”. For example the prefix for the sound stimulus would be phonotaxis, light would be phototaxis and memory would be mnemotaxis. ”Movements toward a stimulus are positive taxes, while movements away from the stimulus are negative taxes (SparkNotes, n.d.)”. Some examples of taxis would be “Phototaxis is the directional movement of animals in response to light (A snake moving towards the light). Thigmotaxis is the directional movement of an animal in response to touch (A cricket jumping away when touched)(MRS. McCOMAS, n.d.)”. With this information from the investigation, we can move on to propose that there is going to be a type of animal behaver that is going to fall into the taxis category from doing this experiment. Whether it will be a positive phonotaxis or the negative phonotaxis response will consider with the results that we will

Extrasensory adaptations – Echolocation: Bats use this sensory system to navigate and locate food. They emit high-pitch sounds that bounce off nearby objects, including prey. The echoes of the sounds are used to determine the distance and direction of those nearby objects. – Pit vipers, boas and pythons have heat-sensing pits that contain heat sensitive sensory receptors. These receptors help these predators sense and locate prey.

nesters avoid making calls or songs; they do not to bring attention to themselves so predators do not locate their nests. Having to locate their nests in the dark, burrow nesters cannot efficiently use visual cues to locate their nests. Moreover, because they avoid making calls and songs, they are unable to use auditory based cues to locate their nests either. In these cases, other forms of communication is needed. Mardon and Bonadonna (2009) assert that olfactory cues are a reliable method of locating their nests in the absence of visual and auditory cues. Specifically, the characteristic smell of the burrow will help them locate it when returning. To test this hypothesis, Mardon and Bonadonna (2009) used a Y-maze experiment to identify the olfactory preferences of petrels, birds known to use burrow nests. In Y maze experiments, one specific odor is placed at each end of the top side, and the bird is placed at the bottom side. The bird is believed to move toward the end that it prefers. In their experiment using storm petrels, recognized and prefered their own scent compared to conspecifics. Further investigation with petrels found that when placed in the Y-maze they prefer the scent of their mate to the odor of another conspecific (Mardon & Bonadonna, 2009). Their studies show that a personal scent exists for avian species, and that they have a preference for their own and
