Ecology In Chlamydomona

In this lab, we studied the health and response of a protist community in an environmental change. The objective of this lab was to study and learn about how variables, such as a more acidic environment, impact the community in a habitat. Furthermore, it was also to learn about how diversity is quantified. To test this, we added protist communities to habitats of different pH levels, from 7 to 4, and let them live there for a week. We then studied the results and investigated which protists lived better in which environments. We discovered that at a pH of 7, the neutral pH of spring water, protists were able to live. As the pH was decreased, however, protists began to die off and could not survive in such acidic conditions. We also noticed that the lower the pH, the lower the diversity because fewer types of protists could survive. We can use this information to see how acidic conditions in nature such as those caused by acid rain can affect communities. We now know that an acidic environment can be extremely harmful to a community and so we should be more cautious of acid rain. If acidic conditions are bad for protists, it is quite possible that they are unfavorable for humans as well.

Chlamydia is a very small microorganism that affects the lining of mucous membranes of the genitals, mouth, anus and rectum. Chlamydia is one of the most common known STD here in the United States, in fact almost 3 million people a year are affected, both men and women. Leaving Chlamydia untreated can cause long term affects and permanent damages. In women it can cause for her to be infertile, and it men can cause his sperm count to be lower and reduce the chances of reproducing. Each year around 100,000 women are infertile from pelvic inflammatory disease. You can attract Chlamydia by having sexual intercourse with someone that has it rather its vaginal, anal or oral sex. There is one way to reduce a sexual transmitted diseases such as Chlamydia, is to have absolutely no sexual intercourse at all.

Chlamydia is a sexually transmitted disease caused by bacterial infection that can be transmitted during sexual contact with an infected person through vaginal anal or oral sex (REF) Symptoms are usually mild and tend to go unnoticed and this is why it Is known as the silent disease (simms 2006) Chlamydia infection can lead to pelvic inflammatory disease; (PID) which is the most preventable cause of infertility (Paavonen and eggert-kruse 1999) and affects around 10-40% of women (Health protection Agency 2009) (HPA). During an episode of PID bacteria can move into the upper reproductive tract and cause the uterus, fallopian tubes and surrounding areas to become swollen and scarred (RISSER AND RISSER 2007). Repeated episodes of PID increase the risk of infertility and ectopic pregnancy and can be more difficult for a woman to become pregnant because her eggs are unable to pass through easily. (SIMMS 2006) It is estimated that 1 in every 10 women with PID become infertile. Although blocked and damaged tubes can sometimes be treated, where this is not possible some woman may consider a procedure called in vitro fertilisation (IVF) to have children. This involves surgically removing eggs from a woman's ovaries and fertilising them before planting the eggs back into the woman's womb.(OAKESHOTT AND KERRY ET AL 2010).

Chlamydia is a well-known sexually transmitted disease that men and women can contract. It can cause damages to a woman’s reproductive system, it can even risk her possibility of pregnancy. Chlamydia can be spread by anal, oral, or vaginal sex with a person who already has the disease. To prevent the risk of catching chlamydia one should practice abstinence. If one plans to practice sexual activities they should be sure their partner and themselves are free from sexual transmitted diseases. Also, using condoms is another way to practice safe sex to prevent sexual transmitted disease and unplanned pregnancy. According to a source from Austin Community College Chlamydia was discovered in 1907 by Stanislaus von Prowazek in Berlin. Signs or symptoms of Chlamydia differ between men and woman. Reshma Suthar states that 50% men don’t experience symptoms and 75% of women. In men signs and symptoms include genital itching, painful urination, discharge from penis, inflamed rectum, inflamed eyelids, and sore and

Some interesting facts on Chlamydia are that it is known as a “silent” disease with 50-75% of people not having any symptoms. Women that are infected are up to 5 times more likely to get HIV if exposed. It is estimated that 1 in 15 sexually active girls under the age of 19 has an active infection at any given time.

When talking about nutrient content and nutrient type in bodies of water (especially lakes), three terms help identify these types of bodies of water- oligotropy, eutropy, and dystrophy. Eutropy refers to the probably the best possible condition for a body of water, because this type of body of water has many nutrients available to it (often in the form of silt) such as phosphorous. These bodies of water are usually near farms or forests and are thriving with life. Algae is a common type of organism that grows in eutropy’s, but can serve as a problem for the survival of other species. Oligotropy is basically the opposite of eutropy condition wise. Oligotropic bodies of water usually have a small amount of organic matter, few nutrients, and especially lack phosphorous. These water bodies are often near terrestrial ecosystems. Dystrophy refers to the condition in bodies of water that have an abundance of organic matter- so much so that the water is often brown. These bodies of water are often near bogs. Lakes can gain these types of nutrients through things such as runoff that bring soil nutrients into the water;

The average yield of total nitrogen between the two rivers differ. The Red River has a slightly higher nitrogen yield in the early data set (1992-1994) than the Sweetwater River (Figure 2A). Whereas, nitrogen yield in the Red River is significantly lower than the Sweetwater in 2005-2007 (Figure 2A). Comparing the two datasets corresponding to years, the Red River showed significant decrease in the average yield of nitrogen (Figure 2A). However, the Sweetwater nitrogen yield has dramatically increased since the earlier data collection (Figure 2A).

Chlamydia, which is caused by C trachomatis, is one of the most common bacterial sexually transmitted disease (STD). Vaginal, anal, and oral sex are the most frequent mode of transmission of Chlamydia, additionally, a neonate can also acquire Chlamydia during delivery, while in the birth canal. During sexual contact, C. trachomatis is introduced into the genital tract, oropharynx, or rectum and evades lysosomal destruction by entering the epithelial vacuoles and multiplying, often with a lack of symptoms. After a period of time, the infection often move to other tissues and organs causing inflammation that may damage the genitourinary and reproductive systems. In the United States, Chlamydia is the most frequent cause of acquired infertility.

In this lab write up, the population growth of a variety of living organisms was analyzed and upon analysis of graphs and background information given within the laboratory course notebook, the conclusion was made that abiotic factors are related to biotic factors in an ecosystem, if one factor is varied it can affect the entirety of the ecosystem. Abiotic factors have importance because they are directly correlated to how biotic organisms survive and the growth or decline of their populations. Abiotic factors refer to non-living physical and chemical elements in the ecosystem and biotic factors are living or once-living organisms in the ecosystem with the ability to reproduce and affect other organisms in the ecosystem.

It’s back to school time and while most people don’t necessarily want to think about it, STD’s are very prevalent among college students. Partying and social engagements, are a big pastime and stress-reliever for many college students, which sometimes result in sexual encounters than can unfortunately, end with one or both parties contracting an STI. While that should not deter students from enjoying themselves, they still need to know about and be safe in regards to sexual encounters during their college career.

Chlamydia is a very common sexually transmitted disease in the United States. It can infect both men and women. Chlamydia is treatable but if left untreated it can cause permanent damage in female reproductive system and in males the damage is rare. Sexually active females and males should be tested every year. This article will review the epidemiology, clinical features, diagnosis, etiology and management of Chlamydia.

Recent surveys in Queensland show that chlamydia has caused symptoms in up to 50 percent of the state's wild koalas, with probably even more infected but not showing symptoms. The first, Chlamydia spectrum, is causing a vast majority of health problems in Queensland's koalas; the second, C. pneumonia, is less common. Chlamydia causes a host of symptoms in koalas, including eye infections, which can lead to blindness, making it difficult for them to find scarce eucalyptus leaves, their primary food source. The epidemic has been particularly severe in Queensland, where nearly all koalas are infected with koala retrovirus, said Dr. Gillett. Treating chlamydia in wild koalas is a challenge, she said. There is no treatment available for koala retrovirus,

On Thursday, October 6th, 2016 I studied the Conodoguinet Creek in Cumberland County, PA. I went to the creek to study the health of the creek itself (Phosphate levels, Nitrate levels, Dissolved Oxygen levels, pH levels, and Alkalinity levels). My hypothesis was: If I test the Conodoguinet Creek for signs of acid rain, eutrophication, or other types of pollution, then the tests will reveal that the creek is healthy and has very low levels of pollution. Eutrophication, is the excessive richness of nutrients in a lake or other bodies of water, frequently due to runoff from the land, which causes a dense growth of plant life and death of animal life due to lack of dissolved oxygen. Dissolved Oxygen (or DO), is the microscopic bubbles

For our project this semester my team studied the effects that a riparian buffer zone had on both Adams Lake and Chapman Pond. We also looked at how climate change effects Adams Lake and Chapman Pond. A riparian buffer zone is where vegetation is grown around a water source to help keep sediment, phosphorous, pesticides, and other harmful things from getting into the water systems (Correll, 2016). The affects that riparian buffer zones have on our water systems and the change in climate is extremely important. My team believed that the water quality would be better in a body of water that had a riparian buffer zone (Chapman Pond) than a body water without a riparian buffer zone (Adams Lake).
