Sound Intensity In Crickets

I believe that underwater noise has an effect on marine animals such as whales. Using information from the passages I will prove my point. Their numbers are declining rapidly and I believe that underwater noise has some involvement in the rapid decrease in their population numbers. The information given within the two passages will help prove my point.

The topic of house cricket aggression in response to residency has been previously studied. (Alexander 1961) split this aggression behavior into five levels: 1) no aggression, dominance, or retreat; 2) no aggression with a retreat by one cricket; 3) mild one-sided aggression with mild repercussion; 4) moderate to intense aggression from both crickets; or 5) sustained combat. Interestingly, in Polistes wasps (Pardi 1948a), Sphecius wasps (Mr Norman Lin, personal communication), and crayfish (Bovbjerg 1953; Lowe 1956) aggressive behavior has been split into four or five levels. (Alexander 1961)

A topic that is known for its controversy is the use of acoustic pingers on fishing nets in an attempt to reduce marine mammal bycatch. While this idea seems appealing and has its potential benefits, there are also drawbacks to the use of this kind of device as well. When a device such as the acoustic pinger is invented, it is important to consider the various types of impacts it will have, especially in terms of marine mammal species conservation.

Weather plays an important role in our daily lives. When we watch weather forecast, we can know whether it will rain next few days. But how do we predict weather conditions? It is a device called meteorological radar. Meteorological radar can provide information like the size, intensity, and height of the target. Actually, besides meteorological radar, there are many kinds of helpful radar without which people will live a totally different life. What contributes to the invention of radar? The answer is bat sonar. Bats can emit a high-frequency sound that people cannot hear, and receive the returning waves to “see” the surroundings. However, how does bat sonar work? What can bat sonar be applied for? Does bat sonar have unanswered problems? These questions will be solved in the following report

Most of these studies involve marine fish and do not look at an aquarium setting. However, a couple of studies have, including Anderson, et al. (2010), which looks at the stress responses of the lined seahorse to chronic noise exposure. Another study looked at the disruption of normal swimming behavior of zebrafishes as well as whether or not they choose a relatively quiet tank over a noisy tank (Neo et al., 2015). However, we could find no study that looked at the effects of a tapping noise on the glass of a tank on aquarium fish. Our distinction of the effects of noise produced by tapping on the glass is important because this externally generated noise could stress fish and have important implications for zoos and aquariums as well as for pet

According to Clive K. Catchpole, studies on song function have demonstrated that Sexual Selection in Acrocephalus Warblers was used for sexual attraction. Furthermore, it was confirmed that after settling with a mate, the singing ceased and that Acrocephalus Warblers resumed the signing if a female left the territory. The purpose of the study is to demonstrate that male Sedge Warblers with more sophisticated songs should attract females before their rivals, who have more simple songs.

This report was done by the evolution and ecology department in the University of California. The area of biological study would have to be animal behavior of the common vampire bat. The discussion or confusion was if vampire bats hunt prey by only using echolocation of some sort of the use of olfaction was part of the hunt. The reason behind the experiment is that in Central and South America there was about over $100 million in damage to livestock due the vampire bats. The hypothesis is that the bats would forage with equal frequencies from blood meals that were and were not associated with the scent of the cattle, so basically it didn’t matter about the smell of the prey the bat was going to get a meal either way. It would be both experimental and an observational study because the experiment is

During the exclusive daytime activity period (15 to 19 August), the juvenile flying squirrels often peeped out of the cavity (Fig. 2A). The juveniles showing such peeping behaviour were estimated to be approximately

Echolocation is widely used by many species which lives in different habitats. The process works when an organism observes acoustic signals, and attains a sense of the space surrounding from noise or echoes that the organism had detected. Animals use echolocation for specific reasons to determine the presence of nearby preys or predators. This way the process of catching or escaping from objects is more efficient to most species. Many marine and land based species use echolocation as a defense against their surroundings. Although some researcher finds echolocation more effective underwater than on land where mainly light is used. Sound can travel through longer complex frequency with objects than light. Many marine mammals use echolocation

Instead of it being a choice between a possible predator and no environment, the cricket was also put under other pressures. For example, the cricket was unnaturally held by a giant freak being which probably freaked it out a bit. In the scareness the cricket may have picked the lesser of two evils; risk being eaten by a lizard or risk the unknown of what a giant freak being might do to it, but the answer to that proposal is testing a cricket’s intelligence in his motives, something not realistic in our experiment. From a distance, it is obvious that our results mean little compared to the questions that have arose during discussion; but we can say that if you take a male cricket that has lived in a science classroom for a bit, and place him in a choice chamber facing the predator side after handling him, and give him the choice of a predator’s terrain and a blank side of the chamber when both sides have been washed with water and dried, there is a 70% chance that he will spend the majority of his time in the predator

Cave crickets have very large hind legs with “drumstick-shapes” femora and equally long, thin tibiae, and long, slender antennae. The antennae are closely apparent and next to each other on the head. They are a brownish color and humpbacked in appearance, always wingless, and the bodies of early instars may appear translucent. Most cave crickets favor cool/damp places like caves, rotten logs, underneath leaves or rocks and will not reproduce indoors unless they find continuous darkness, and moist conditions. Living in perpetual darkness, as deep in caves, may have reduced and missing eyes and often have long slender limbs. Most of these crickets are omnivorous and will eat on most anything organic. Most will catch and eat other smaller animals when they can. If they are in houses, they may chew on paper products and occasionally fabric. They can grow up to 5 cm in body and 10 cm for the legs. They are found worldwide and is widespread in North America, south of Arctic

There are 900 species of crickets; one of the most common species, used a lot of times for bait, is the house cricket or Acheta Domesticus. Most species of crickets are nocturnal meaning they are more active at night. House crickets tend to be found in the Eastern part of the United States. House Crickets have shorter lifespans than most other species of crickets living only about three months while other cricket species such as the mole cricket can live for about a year.

This study’s purpose was to learn and investigate the different aspects of Batesian mimicry, learn bird species common to the area, their different foraging behaviors, and investigate if a modification to their foraging behaviors can be implemented through learning. We will also measure the
