Biology 124 Lab Case Study "No Bats in the Belfry: The origin of White-Nose Syndrome in Little Brown Bats" Part 1 Questions 1. What is the basic question of the study and why is it interesting? The basic question of thIs study is "Is the European strand of Pseudogymnoascus destructans causing White-noise syndrome (WNS) in the United States?" This question is interesting because if it is the European strand of P. destructans causing WNS in North America then why is it not occurring in as high of levels and why are bats not dying in as big of a capacity in Europe as the bats in North America. 2. What specific testable hypotheses can you develop to explain the observations and answer the basic question of this study? Write at …show more content…
2. Describe an experiment you could use to differentiate between the null and alternative hypotheses. An experiment could be devised in which bats are taken in a large quantity and one group in injected with the North American P. destructans strand, a second group is injected with the European P. destructans strand and a third group is injected with a placebo. The bats should be placed in a cave like setting and the effects of the injections should be examined. Part 3 Questions 1. Use the graph below to predict what the results will look like if the null hypothesis is supported. The total arousal counts in the control treatment at each interval is graphed for you. Justify your predictions. 2. Use the graph below to predict what the results will look like if the null hypothesis is rejected. The total arousal counts in the control treatment at each interval is graphed for you. Justify your predictions. Part 4 Questions Study Results 1. How do your predictions compare with the experimental results? Be specific. My predictions for the acceptance of the null hypothesis were very similar to the actual results with a few variations. My prediction of total arousal times for the first interval were the same however, on the second interval I had 60 total arousal times for the bats injected with the European P. destructans strand and the actual results had a total arousal of 80 bats injected with the European strand at interval
Pseudogymnoascus destructans, the scientific name for White-Nosed Syndrome is a cold dwelling fungus that has been running rapid in the United States. The disease has made prevalence here after being brought over from Europe and Asia. Research has even been found that bats in Europe may
It is also possible that a number of other random experimental errors (not mentioned above) affected the results of this experiment (for example the possible death of flies and their offspring due to mites and mould). These random errors could also be overcome by doing a large number of trials using a larger number of flies than used in this experiment.
There is a debate between scientists whether vampire bats should be killed or not. Firstly, ranchers, believe that vampire bats should be killed. For example, Chris Kraul a writer for the Los Angeles Times, shares that bats are feasting and killing off the cattle. Thus, this point proves that bats should be killed(Kraul). Secondly, Researchers believe that bats should be saved. For instance, Kraul reports that the theory for all of the attacks on the livestock are cause by timber cutting so the bats are losing food rich forests so they head toward the cattle for food. Therefore, this confirms that it is our fault for the bats attacking the livestock. Thirdly, I believe that bats should not be killed. To illustrate, Kraul tells bat based research
6. Analyze results - Graph the data from Table 4 and describe what your graph looks like (you do not have to submit a picture of the actual graph).
When the pollution affecting the Peppered moths was studied there were a few highlights. When there was more pollution, there was
There is not much information on white nose syndrome. The disease was first documented in New York in the winter of 2006 and has quickly made its way south, into Virginia and beyond. White nose syndrome spreads quickly and targets bats hibernating in infected caves. The syndrome has already killed millions of bats on the eastern half of the United States. The disease impacts a colony over the course of 2 to 3 years before it reaches a deadly state, so the effects are continuing to grow in many areas. Research in this area is vital at this stage.
To start new laws and community would need to be put forth to ensure that the Indiana bat is not disturbed during their hibernation in caves. One way to complete this is by working with the local government to install gates to block access to the caves when the Indiana bat is hibernating. Another way to help ensure the survival of this species would be to put forth community education to help raise funds and awareness in finding cure for the white-nose syndrome (Animals-Moms.me 2016). I do not believe that these change would not require that much sacrifice from us humans in order to ensure the survival of this species. I do not believe the extinction of this species would have a large negative affect on humans, but seeing as it is one of many species of bat’s currently affected by the white-nose syndrome. With this issue in mind the extinction of this species could cause a large misbalance within their
All the brown bat are dying because the fungus is infection that the bat have that’s why they are dying out. That’s why the bat’s are dying to fast and in New Jersey were 30,000 bat. The fungus kill all most every bat because in 2008 where 30,000 but then it was only 300 left, the fungus work better in other bats because when they are asleep the fungus make them move around.
Northern Long-eared bats consume the insects that are posing a threat to our agriculture such as beetles, flies, and moths. If the Northern Long-eared bat became absent, our agriculture would be pushed into more harm’s way. Besides, the bats are out of our habitat, therefore, we should stay
White nose syndrome is a fungus that grows on hibernating bats’ muzzles that has killed nearly 6 million of them. Although traditionally found in most if not all eastern states, bats in caves as far south as Mississippi, as far west as Oklahoma, and as far north as Canada have been found with the devastating fungus. Infecting 47 species of bats, the disease was first noticed in the winter of 2006-2007 in New York, because of the odd behavior of the bats. It was later discovered that the fungus, Pseudogymnoascus destructans, causes infected bats to exhibit uncommon behavior such as flying during the day. Scientist have discovered that this fungus, which distributed hydration cycles, caused the bats to awake early during hibernation in order
Approximately half of all bats that get treated will return to the wild. However, not all bats can be treated. Those infected organisms that are deemed non-releasable have to be humanely put down. When a bat is found with WNS, it not only suffering due to the infection, but due to exposure and dehydration as well. There are several precautions and steps it takes to nurse an infected bat to health.
In his article “Let There Be Dark”, Paul Bogard builds a persuasive argument through a series of effective examples that natural darkness needs to be preserved. To prove his main argument, Bogard implements facts and statistics about the negative effects of light pollution such as the carcinogenic effects of a lack of darkness, the dependency of flora and fauna on natural darkness, and the inspiration sparked through the stillness provided by darkness. Even though humans are the only living things contributing to artificial light at night, the decreasing amount of natural darkness is negatively affecting people’s health. For most people, this problem does not seem evident, since we still spend about eight hours every day sleeping in darkness. Bogard makes this issue seem more tangible by classifying the job of working the night shift as a carcinogen, stating that “our bodies need darkness to produce the hormone melatonin, which keeps certain cancers from developing, and our bodies need darkness for sleep.”
emitted one after the other, the bat can determine if an insect is moving away or towards the bat,
The first possible method for protecting the bats, would be to setup a protected area. Positive incentive driven programs and eco-tourism just won’t work with bats. Bats don’t have the same general appeal as something like a polar bear or panda. People generally don’t find bats to be likeable, and so convincing people to protect them likely wouldn’t gain much traction. Instead, a controlled area that quarantines the healthy population of bats away from their infected counter-parts and human interaction would be their best shot. The healthy bats need to be kept away from the infected ones. Since going out to capture all of the healthy population in not feasible, I suggest capturing a small, but viable, sample of healthy bats for contained breeding. As the bats reach maturity they could be released into the protected area to reproduce and increase the population of healthy bats. Funding this operation would be tricky, but if the facts are laid out, the government could be persuaded to aid in funding the project. After raising the point of how the bats function for efficient and free pest control (in what would other-wise be an impossibly expensive service by humans) the government would likely see that the more financially
Here are some things I know about bats. Bats are nocturnal, which means they are active at night. They use echo location. Bats aren’t very good with their eyesight, they’re nearly blind! So for this they use their hearing, which is echo location. With echo locations bats send out a sound which spreads out, other animals in the location have these sounds bounce off their body going back to the bat. Which then helps the bats find prey or help with their motion of direction. Bats are also mammals this means they are warm blooded. Some bats carry diseases so if you got a nasty bite from a bat you could possibly get ill.
