Rural ecology

History of ecology The roots of ecology as a broader discipline can be traced to the Greeks and a lengthy list of developments in natural history science.

Is a vaccine available to prevent plague? Plague is an infectious disease that affects rodents, certain other animals, and humans. It is caused by the Yersinia pestis bacteria. These bacteria are found in many areas of the world, including the United States.

How do people become infected with plague? People most commonly acquire plague when they are bitten by a flea that is infected with the plague bacteria. People can also become infected from direct contact with infected tissues or fluids while handling an animal that is sick with or that has died from plague.

Finally, people can become infected from inhaling respiratory droplets after close contact with cats and humans with pneumonic plague.

What are the different forms of plague? There are three forms of plague: Patients develop sudden onset of fever, headache, chills, and weakness and one or more swollen, tender and painful lymph nodes called buboes.

This form is usually the result of an infected flea bite. The bacteria multiply in the lymph node closest to where the bacteria entered the human body.

If the patient is not treated with appropriate antibiotics, the bacteria can spread to other parts of the body. Patients develop fever, chills, extreme weakness, abdominal pain, shock, and possibly bleeding into the skin and other organs.

Skin and other tissues may turn black and die, especially on fingers, toes, and the nose. Septicemic plague can occur as the first symptoms of plague, or may develop from untreated bubonic plague.

This form results from bites of infected fleas or from handling an infected animal. Patients develop fever, headache, weakness, and a rapidly developing pneumonia with shortness of breath, chest pain, cough, and sometimes bloody or watery mucous.

Pneumonic plague may develop from inhaling infectious droplets or from untreated bubonic or septicemic plague that spreads to the lungs. The pneumonia may cause respiratory failure and shock.

Pneumonic plague is the most serious form of the disease and is the only form of plague that can be spread from person to person by infectious droplets.

Top of Page What is the basic transmission cycle of plague? Fleas become infected by feeding on rodents, such as chipmunks, prairie dogs, ground squirrels, mice, and other mammals that are infected with the bacterium Yersinia pestis.

Fleas transmit the plague bacteria to humans and other mammals during a subsequent feeding. The plague bacteria survive briefly a few days in the blood of rodents and for longer periods in the fleas. An illustration of plague ecology in the United States is available.

Yes, when a person has plague pneumonia they may cough droplets containing the plague bacteria into air. If these bacteria-containing droplets are breathed in by another person they can cause pneumonic plague.

Human-to-human transmission is rare and typically requires direct and close contact with the person with pneumonic plague.The importance of ecosystem services for rural inhabitants in a changing cultural landscape in Romania Tibor Hartel 1,2, Joern Fischer 2, Claudia Câmpeanu 3, Andra Ioana Milcu 2, .

Urban Ecology is the study of ecosystems that include humans living in cities and urbanizing landscapes.

It is an emerging, interdisciplinary field that aims to understand how human and ecological processes can coexist in human-dominated systems and help societies with their efforts to become more sustainable. Genus. Genus or in plural genera is known as the taxonomical hierarchy above species containing one or multiple species under it.

The further hierarchy in taxonomy contains family. The three-day fire killed people, destroyed 17, buildings and paved the way for the kind of steel and concrete construction that dominates the industry to this day.

What is Human Ecology? Ecology is the science of relationships between living organisms and their ecology is about relationships between people and their environment.

In human ecology the environment is perceived as an ecosystem (see Figure ). An ecosystem is everything in a specified area - the air, soil, water, living organisms and physical structures, including.
