Botanists study plants and their environments. Some study all aspects of plant life, including algae, fungi, lichens, mosses, ferns, conifers, and flowering plants; others specialize in areas such as identification and classification of plants, the structure and function of plant parts, the biochemistry of plant processes, the causes and cures of plant diseases, the interaction of plants with other organisms and the environment, and the geological record of plants.

Many botanists do field studies that involve strenuous physical activity and primitive living conditions. Biological scientists in the field may work in warm or cold climates, in all kinds of weather.

Biological scientists should be able to work independently or as part of a team and be able to communicate clearly and concisely, both orally and in writing. Those in private industry, especially those who aspire to management or administrative positions, should possess strong business and communication skills and be familiar with regulatory issues and marketing and management techniques. Those doing field research in remote areas must have physical stamina. Biological scientists also must have patience and self-discipline to conduct long and detailed research projects.

A Ph.D. degree usually is necessary for independent research, industrial research, and college teaching, as well as for advancement to administrative positions.

A master's degree is sufficient for some jobs in applied research, product development, management, or inspection; it also may qualify one to work as a research technician or a teacher.

The bachelor's degree is adequate for some nonresearch jobs. For example, graduates with a bachelor's degree may start as biological scientists in testing and inspection or may work in jobs related to biological science, such as technical sales or service representatives. Some work as research assistants, laboratory technicians, or high school biology teachers.

Some work as consultants to businesses or to government agencies. Others choose to move into managerial positions and become natural science managers. They may plan and administer programs for testing foods and drugs, or direct activities at zoos or botanical gardens.

Biological scientists held about 87,000 jobs in 2006. Almost 40 percent of all biological scientists were employed by Federal, State, and local governments. Federal biological scientists worked mainly for the U.S. Departments of Agriculture, Interior, and Defense and for the National Institutes of Health. Most of the rest worked in scientific research and testing laboratories, the pharmaceutical and medicine manufacturing industry, or colleges and universities.

Median annual earnings of biochemists and biophysicists were $76,320 in 2006. The middle 50 percent earned between $53,390 and $100,060. The lowest 10 percent earned less than $40,820, and the highest 10 percent earned more than $129,510.

Median annual earnings of microbiologists were $57,980 in 2006. The middle 50 percent earned between $43,850 and $80,550. The lowest 10 percent earned less than $35,460, and the highest 10 percent earned more than $108,270.

Median annual earnings of wildlife biologists were $53,300 in 2006. The middle 50 percent earned between $41,400 and $67,200. The lowest 10 percent earned less than $32,800, and the highest 10 percent earned more than $84,580.

In the Federal Government in 2007, general biological scientists earned an average salary of $72,146; microbiologists, $87,206; ecologists, $76,511; physiologists, $100,745; geneticists, $91,470; zoologists, $110,456; and botanists, $67,218.
