 The decline is cheetahs throughout their range is mostly due to capture and trade, as well as being hunted for their skins. Historically, they were hunting trophies for Europeans who traveled to Africa in the 1800s. While it is illegal to hunt them today, they are still poached for their skins or captured to be used as exotic pets. Another large contributor to their threatened status is that they face large habitat loss. Urbanization, and agriculture disturb their natural areas reducing their range, so much so that there are now areas of protected land for them, hoping to save the remaining numbers. But they are those that live outside those lands and face conflict with farmers who kill the cheetahs to protect their livestock. Human expansion has also effected the cheetahs food source. In some areas, it is hard for cheetahs to find food, and instead they will try to prey on farmed animals and risk death. A biological contributor to decline is that since the numbers of cheetah are already so low, the chances of inbreeding is higher, making members of a population very close genetically. If a disease were to befall a couple individuals, it could potentially wipeout the entire population in that area. 

    The cheetah (Acinonyx jubatus) is a wild cat found scattered around in small parts of Africa and in Iran. It is famous for being the fastest land animal on the planet, reaching speeds up to 75 miles per hour. There are five subspecies; four that are African and one that is Asian. According to a research paper titled The global decline of cheetah and what it means for conservation by Sarah M. Durant and her team, the cheetah’s historic range was most of Africa (excluding parts of central Africa, Egypt, and Madagascar) and the Middle East into India. Today, cheetahs have lost 98% of their range in Asia, and the Asian Cheetah (Acinonyx jubatus venaticus) is critically endangered with an estimated 50 individuals. In Africa, the remaining four subspecies live only on 13% of the land they once inhabited, causing the Northwest African Cheetah subspecies (Acinonyx jubatus hecki) to also become critically endangered. As of 2014, the known cheetah population is about 6700 individuals over 29 subpopulations (Durant).

We will investigate the effect resource petitioning can have upon two species of birds that exist within the same habitat. The goal of this study is to analyze differences between beak size and shape, habitat and how they obtain their food. We will use the University of Massachusetts Amherst avian collection to collect data on bill length, depth, and width from preserved bird skins. We will use this collection because it will allow us to compare beak measurements of different species using a primary source of data. We will also use reliable ornithology research articles to find information on habitat types, behavior, and diet that will be used to compare bird species.

    There are two main types of people, either you are a morning person who likes to sleep early and wake up early, while others like to wake up late, and sleep late. Is there a better version to be? The answer as of right now, is actually being a morning person. The reason why is because society was built on the premise of waking up early, getting to work, and finishing by the evening to enjoy the rest of the day. This means that those who are naturally morning birds, are able to work with the flow of society, and get the most out of it; while those who are night owls tend to have a lot of difficulty getting up for work in the morning. There’s been very recent research done that shows a strong disparity between minorities and caucasians, demonstrating that on average those who are caucasian or of latino descent, tend to be morning birds while those who are from asian or european descent, tend to be night owls. The research points to how our ancestors were used to a different type of circadian rhythm, and while the place we live in plays a major role in how we sleep and when we like to wake up, it’s possible that we have genes that are programmed for us to sleep  and wake up at specific times based off where our ancestry’s from.

Biodiversity is an important feature in any ecosystem, and lawns are no exception. The data obtained from this study will not only offer some insight into the effects of common maintenance practices on lawn biodiversity in Amherst, Massachusetts, but will also set the stage for more research that could be done on the topic. The data will be a useful aid in future decisions both about how lawns should be maintained, and about how these practices can be used to aid in the conservation of the natural plant diversity in Amherst. It can also provide a framework for efforts to slow the decline of biodiversity in green spaces, for example by highlighting which areas have the most biodiversity and how that correlates with how these areas are maintained. This can allow for individualized tailoring of maintenance practices for each lawn or green space based on the plant species that inhabit it, and also provide information about which areas could benefit from the introduction of new species to increase the floral diversity.

    Everybody has a different approach when it comes to studying for an exam. Some people will take weeks before an exam and study bits and pieces until the day of the exam, and others will wait until the day of the exam to start studying. It starts to beg the question, which method is the ‘correct’ method? Research has actually shown that on average, studying 4 to 6 days in advance for any exam is most likely the best way to study for an exam. The first 3 to 4 days are used to study the material in parts, and by the end of the 3rd or 4th day, all the material will have been sufficiently reviewed. Come the following 5th and 6th day, those days are used as days to comprehensively review the material. The reason why research supports this method of studying, is because of the amount of sleep that a student is able to get in between each study session. The amount of sleep a student gets in between learning material plays a huge role in memory and retention. By being able to sleep multiple nights between comprehensive material, the student is able to understand and remember the information a lot better than if they were to cram the night before. The reason why you don’t want too many nights in between during studying though, is because the brain does eventually forget information, especially if it isn’t being used on a daily basis. With that said, studying anymore than 6 days ahead of an exam can actually work against your favor as you begin to start to forget some things you learned at the very beginning.

    The other day, I was invited over to my caucasian friend’s place back in Lowell (his race is important in this context). When we stepped in through the front door, I was in the process of taking off my shoes when he told me “oh, don’t take your shoes off, we don’t do that here”. This was the first time I had never taken off my shoes inside someone’s house. I was a bit thrown back, and asked “Why? Do you not take your shoes off?, and he replied with “No, not really”. I was still a bit surprised but did not want to be disrespectful, so I walked through the house with shoes on, and could only think about how gross it was. When we walked into his furnished basement, I couldn’t believe how dirty the carpet was as it was covered in dirt stains. As we hung out a bit more, I could not process the idea that I still had my shoes on. I then had to ask “do you sleep with your shoes on?”, to which he replied with “of course, you don’t?”. I couldn’t believe it. The amount of bacteria that is on the streets and outside, and the idea of bringing that inside, and tracking it everywhere in the house seemed disgusting to me.

Lawns create the feeling of a natural environment in urban areas, offsetting the health liabilities that typically befall city residents (Irvine et al., 2003), essentially contributing to the overall well-being of the people. Urban green spaces also serve as grounds for recreation and the development of social connection. As for the presence of green spaces on campuses, studies have revealed that there is indeed a correlation between presence and use of green spaces, and perceived student quality of life (McFarland, 2008). This speaks to the fact that lawns or UGSs have vital psychological benefits to humans. Lawns also possess some ecological significance as they contribute to the conservation of biodiversity in urban settings.

The data will be a useful aid in future decisions both about how lawns should be maintained, and about how these practices can be used such that floral diversity is maintained. It can also offer a framework for efforts to slow the decline of biodiversity in green spaces, for example by highlighting which areas have the most biodiversity and how that correlates with how these areas are maintained. This can allow for individualized tailoring of maintenance practices for each lawn or green space based on the plant species that inhabit it, and also provide information about which areas could benefit from the introduction of new species to increase the floral diversity.

Beyond the ecological aspect of maintaining green spaces, there is also the psychological value that lawns have.

In 1866, John Langdon Down, physician and medical superintendent of the Earlswood Asylum in Surrey, England, noticed a remarkable resemblance among a number of his intellectually disabled patients: all of them possessed a broad, flat face, a small nose, and oval-shaped eyes. Their features were so similar, in fact, that he felt that they might easily be mistaken for children from the same family. Down did not understand the cause of their intellectual disability, but his original description faithfully records the physical characteristics of people with this genetic form of intellectual disability. In his honor, the disorder is today known as Down syndrome.

“Some opponents of active euthanasia do not oppose it morally but worry that if doctors have the power to kill patients, they may use it too freely. Thus, much of the opposition to active, voluntary euthanasia comes from the fear that, if it is legalized, it will be abused. (1)” Giving a doctor far too much power and control gives humans a large sense of vulnerability. Doctors already have a control over other’s lives, euthanasia would not be any different. For euthanasia a patient must be the one to decide what will happen to them as well as have to sometimes undergo a psychological test to ensure that their decision is definite. “Advocates of physician-assisted suicide insist that it is inherently voluntary. The doctor prescribes the lethal medication, but the patient must choose to swallow the pills. (1)” Both of these versions it is the patient who is the one who desires to end their life and who makes the ultimate decision in going through with the process. These people are willing patients who have gone through a life that will not get any better, usually having an incurable disease.
