Waltke - Biology Pd 5 - By Thomas Wisnieski

Definition of Ecology

Ecology is the branch of Biology that deals with living organisms and how they react to other organisms and their environment around them. Ecology is a field that combines biology and Earth science. Ecologists study the diversity, distribution, biomass, and population of certain organisms. They also study how those organisms communicate within each other.


Rachel Carson

Rachel Carson was born on May 27, 1907 in Springdale, Pa. From 1925-1929 Carson attended Pennsylvania College for Women and majored in science. In 1935, she wrote her first book "The World of Water", later published as "Undersea" in Sept. 1937. From 1935-1952 she was appointed the Junior Aquatic Biologist with the Bureau of Fisheries. In 1952 she won the National Book Award for Non-fiction for The Sea Around US. In April of 1960, Carson had radical mastectomy for breast cancer. Then on April 14, 1964, Carson died at the age of 56 in Silver Spring Missouri.

When Rachel Carson came out of the Pennsylvania College for Women, she starting writing radio scripts for the U.S Bureau of Fisheries. She also wrote pamphlets on conservation and natural resources and edited scientific articles. In her free time she wrote lyric prose from her government research. When War ll came around, Carson was disturbed by the synthetic chemical pesticides. She then turned her focus to inform the world of the long term effects of the pesticides. In Silent Spring, she challenged the practices of agriculture scientists and the government. She died in 1964 after a long battle with breast cancer.

Rachel Carson was a big person when you reflect on Ecology because she warned us about the what the environment was like around us with the pesticides after WWII.

Alan Rabinowitz

Alan Rabinowitz was born on December 31, 1953, in Brooklyn, New York. In 1974, Alan graduated from Western Maryland College, earning a bachelor's degree in biology and chemistry. Later he graduated from the University of Maryland, getting his M.S and Ph.D in ecology in 1978 and 1981. Alan also started the first jaguar sanctuary in 1986. He founded the leaf dear in 1997. Today, Alan Rabinowitz is the CEO of Panthera, a charitable organization protecting big cats.

When Alan Rabinowitz graduated from the University of Maryland, he went to work. In Belize, his work resulted in the world's first jaguar sanctuary. His studies in Taiwan resulted in the establishment of the country's largest protected animal area. He also created another protected area in Myanmar because of his studies. In northern Myanmar, he discover a species called the leaf dear. Because of his studies, he realized how the animals behaved in the environment and that they needed to be take of better.

He studied how jaguars and other big cats and animals behaved in the environment around them, and that is Ecology.

Dian Fossey

Dian Fossey was born in San Francisco in 1932. She graduated from San Jose State College in 1954 with a degree in occupational therapy. In 1963, Dian Fossey took a bank loan to go to Africa for the first time. In September 1963, she got to Kenya. In 1966 she got to show her locally published articles to Dr. Louis Leakey, a Kenyan archaeologist. Leakey then paid for Dian's trip back to Africa in December 1966. She died in 1985 after an amazing study of gorillas in Africa.

When Dian went to the Kenya for the first time, she became fascinated with the gorillas and dreamt of the day she'd return. The second time she went to Africa, Dr. Lois Leakey sent her to Kabara, where she resumed studying gorillas. She began to almost befriend the gorillas, scratching them, feeding them, and even copying their contentment vocalizations. Along with friends she made in Africa, she developed the Karisoke Research Center. Along the road, she felt people were looking over her, so she set out to get her Ph.D, which she got in 1974. After she got her Ph.D, she realized that there were risks to gorillas being killed by poachers. The gorillas weren't necessarily the ones being targeted, but they would get caught in the poacher's traps. Dian would particularly hate the poachers, because they killed her best gorilla friend, DIgit, while he was protecting the rest in his group. She would rage war on the poachers, and eventually return back to New York. Back in her cabin on the morning of December 27, 1985, she was murdered. She lived to be 54 years old.

Dian Fossey was basically the Alan Robinowiz for gorillas. She studied them and and how they reacted to their environment.
