Her papers are not cited thousands of times, though the central ideas that she developed permeate the field. Her contemporaries often referred to her ideas in conversation, though they often failed to appropriately cite her work. She was regarded as a member of the academic community as an unparalleled natural historian of ants, but her contributions were much greater, shaping our thinking on a wide range of topics, including how animals evolve and adapt to variation in weather and climate, and the relationships among animal life histories and the assembly of ecological communities.

As an ant biologist, reading her papers anew makes me realize how many ideas in the latter half of the 20th century came straight from Talbot, but we often failed to value these contributions even as we relied on them. At the moment, Dr. There are additional details about her career in this biography, in an appendix attached to a publication that was compiled after her death, summarizing some her work at the George Reserve.

There are oodles of talented women myrmecologists nowadays, though a survey of the literature shows that underrepresentation persists , particularly among taxonomists. The academic culture in my own subfield still is not equally welcome to men and women, and by recognizing this fact we can identify changes to become more inclusive. Sorry to have missed the Aug 10 event, but being at Portal during the 30 hour power outage was just as good in its own way.

It strains the algae from the water. Flamingos keep the number of red algae down. This helps the fish. Red algae live in saltwater.

When they bloom, they produce poison. Scientists call them HABs harmful algae blooms. Few areas of U. He became a forest ranger and spent years in the woods. Then one day, he did something that changed his life. Leopold lived in a time when there were no game laws. If a person wanted to kill an animal, he could. When Leopold was a young man, he shot a wolf. As he watched it die, he felt guilty.

The wolf had not threatened him. He had killed it for no reason! It struck him that every living thing was part of an ecosystem.

He had just damaged it without cause. Leopold urged others to stop killing animals for no reason. It took him years to convince others that wildlife should be preserved. He fought to get laws passed.

He became the leader in the field of game management. He pushed for game preserves and national forests. He wanted these areas set aside. Then nothing would spoil their natural beauty. The gray wolf has made a comeback. Ranchers used to shoot wolves because they attacked their cattle. The species was near extinction. Laws were passed to make shooting wolves illegal. Without hunting, the wolf population grew back. Now lawmakers are making new laws to allow just enough wolf hunting to keep their numbers balanced. Lost Birds The extinction of the passenger pigeon is a shocking story.

This bird species was once the most numerous on Earth! Yet they were shot for sport until none were left. The last one died at the age of 29 at a zoo in Long ago, dodo birds lived on one island in the Indian Ocean. They could not fly. This made them easy to catch and eat.

Pigs came and ate their eggs. By , there were no more dodo birds. These stuffed passenger pigeons can be found in a museum.

The first was passed in It is the National Environmental Policy Act. It states that the government must first think about the environmental effects of any land use.

      It is stored inside the fat in our glands. When the fat was used, it made people sick. Ruth Patrick More Salt? Patrick proved that Great Salt Lake in Utah was once fresh.

      It became salty through evaporation. Ruth Patrick has loved nature since she was young. Her dad took her on walks. They would pick up things. Then they looked at them under a microscope. When she grew up, she started the science of limnology. It is the study of freshwater ecosystems. Patrick was the first to determine the health of a river or stream. She did this by collecting diatoms DAHY-uh-tomz. These are single-celled algae. They are a basic food source for things living in freshwater. Different diatoms prefer different environments.

      So, their presence is linked to water quality. To get diatoms, Patrick invented a device. It shows the presence of pollution in freshwater. First it is placed in the water. Then it is anchored to the bottom. A cork keeps it afloat. As the water moves through it, diatoms attach to glass slides. The slides are removed and studied. Ecologists today still use her methods. They measure changes in amounts and kinds of plants, animals, and bacteria. This lets them gauge the impact of pollution.

      They can also detect other changes. The team gathered data about the water quality and things living in the Savannah River. The things he learned there helped him to form important ideas about ecology. Eugene Odum may be the most important ecologist of the 20th century. He saw Earth as a set of interlocking ecosystems. He urged people to study the ecosystem as a whole.

      At first, this idea had little support.
