Elmer Yale Dawson
Elmer Yale Dawson (March 31, 1918 – June 22, 1966) was an American botanist, phycologist, taxonomist, ecologist, and naturalist writer. He popularized science and natural history with his books and articles on topics ranging from California cacti and North American cacti, to California seashore plants and marine algae, desert plant ecology, salt marsh wetlands, and anthropology topics including ethnohistory and ethnobiology of Seri Native American Indian culture of the northern Gulf of California. Biography Dawson was born in on March 31, 1918 in Creston, Iowa to Elmer Clarence Dawson and Mabelle Davidson Campbell. The family moved west to Los Angeles County, California, residing in a home in the City of Long Beach as a boy and during his teen years, just a few blocks from the Pacific Ocean. He grew cacti in the family backyard, and even salvaged a large Saguaro Cactus from near the Colorado River, where a new dam would soon flood the habitat and drown this cactus. The Sag ...

Creston, Iowa
Creston is a city in and the county seat of Union County, Iowa. The population was 7,536 at the time of the 2020 Census. History Creston was originally settled in 1868 as a survey camp for the Burlington and Missouri Railroad. It was named for the fact that it was on the crest of the railroad line between the Missouri and Mississippi river basins. The area was developed largely for agriculture, with related industries accompanying it. Creston had a flour mill in the early decades of the 20th century. The town was officially established in 1869 and incorporated in 1871. Creston was chosen as the division point for the railroad, who built machine shops, a roundhouse, and a construction camp in the new town. Railroad employees, including African Americans, were recruited from Chicago and other major cities to work in Creston. The Chicago, Burlington and Quincy Railroad (CB&Q) opened a new station in Creston in 1899. The three-story, yellow brick Creston station is in the Frenc ...

United States Army
The United States Army (USA) is the land service branch of the United States Armed Forces. It is one of the eight U.S. uniformed services, and is designated as the Army of the United States in the U.S. Constitution.Article II, section 2, clause 1 of the United States Constitution (1789). See alsTitle 10, Subtitle B, Chapter 301, Section 3001 The oldest and most senior branch of the U.S. military in order of precedence, the modern U.S. Army has its roots in the Continental Army, which was formed 14 June 1775 to fight the American Revolutionary War (1775–1783)—before the United States was established as a country. After the Revolutionary War, the Congress of the Confederation created the United States Army on 3 June 1784 to replace the disbanded Continental Army.Library of CongressJournals of the Continental Congress, Volume 27/ref> The United States Army considers itself to be a continuation of the Continental Army, and thus considers its institutional inception to be th ...

Cacti
A cactus (, or less commonly, cactus) is a member of the plant family Cactaceae, a family comprising about 127 genera with some 1750 known species of the order Caryophyllales. The word ''cactus'' derives, through Latin, from the Ancient Greek word (''káktos''), a name originally used by Theophrastus for a spiny plant whose identity is now not certain. Cacti occur in a wide range of shapes and sizes. Although some species live in quite humid environments, most cacti live in habitats subject to at least some drought. Many live in extremely dry environments, even being found in the Atacama Desert, one of the driest places on Earth. Because of this, cacti show many adaptations to conserve water. For example, almost all cacti are succulents, meaning they have thickened, fleshy parts adapted to store water. Unlike many other succulents, the stem is the only part of most cacti where this vital process takes place. Most species of cacti have lost true leaves, retaining only spines, ...

Rhodophyta
Red algae, or Rhodophyta (, ; ), are one of the oldest groups of eukaryotic algae. The Rhodophyta also comprises one of the largest phyla of algae, containing over 7,000 currently recognized species with taxonomic revisions ongoing. The majority of species (6,793) are found in the Florideophyceae (class), and mostly consist of multicellular, marine algae, including many notable seaweeds. Red algae are abundant in marine habitats but relatively rare in freshwaters. Approximately 5% of red algae species occur in freshwater environments, with greater concentrations found in warmer areas. Except for two coastal cave dwelling species in the asexual class Cyanidiophyceae, there are no terrestrial species, which may be due to an evolutionary bottleneck in which the last common ancestor lost about 25% of its core genes and much of its evolutionary plasticity. The red algae form a distinct group characterized by having eukaryotic cells without flagella and centrioles, chloroplasts tha ...

Marine Algae
Marine primary production is the chemical synthesis in the ocean of organic compounds from atmospheric or dissolved carbon dioxide. It principally occurs through the process of photosynthesis, which uses light as its source of energy, but it also occurs through chemosynthesis, which uses the oxidation or reduction of inorganic chemical compounds as its source of energy. Almost all life on Earth relies directly or indirectly on primary production. The organisms responsible for primary production are called primary producers or autotrophs. Most marine primary production is generated by a diverse collection of marine microorganisms called algae and cyanobacteria. Together these form the principal primary producers at the base of the ocean food chain and produce half of the world's oxygen. Marine primary producers underpin almost all marine animal life by generating nearly all of the oxygen and food marine animals need to exist. Some marine primary producers are also ecosystem en ...

Stanford University
Stanford University, officially Leland Stanford Junior University, is a private research university in Stanford, California. The campus occupies , among the largest in the United States, and enrolls over 17,000 students. Stanford is considered among the most prestigious universities in the world. Stanford was founded in 1885 by Leland and Jane Stanford in memory of their only child, Leland Stanford Jr., who had died of typhoid fever at age 15 the previous year. Leland Stanford was a U.S. senator and former governor of California who made his fortune as a railroad tycoon. The school admitted its first students on October 1, 1891, as a coeducational and non-denominational institution. Stanford University struggled financially after the death of Leland Stanford in 1893 and again after much of the campus was damaged by the 1906 San Francisco earthquake. Following World War II, provost of Stanford Frederick Terman inspired and supported faculty and graduates' entrepreneu ...

Ed Ricketts
Edward Flanders Robb Ricketts (May 14, 1897 – May 11, 1948) was an American marine biologist, ecologist, and philosopher. He is best known for ''Between Pacific Tides'' (1939), a pioneering study of intertidal ecology. He is also known as a mentor who influenced the writer John Steinbeck, which resulted in a collaboration and coauthorship of the book, ''Sea of Cortez'' (1941). Eleven years later, and just 3 years after the death of Ed Ricketts, John Steinbeck reprinted the narrative portion of their coauthored book with a new publisher, but removed Ed as coauthor, while adding a biography of Ed Ricketts, and Steinbeck made a new title for the book as ''The Log from the Sea of Cortez'' (1946). Steinbeck also added a eulogy for Ricketts, though it was met with public backlash. Life Ricketts was born in Chicago, Illinois, to Abbott Ricketts and Alice Beverly Flanders Ricketts. He had a younger sister, Frances, and a younger brother, Thayer. His sister, Frances (Ricketts) Strong, ...

Between Pacific Tides
''Between Pacific Tides'' is a 1939 book by Edward F. Ricketts and Jack Calvin that describes the intertidal ecology of the Pacific coast of the United States, Canada, and Mexico. The book was originally titled "Between Pacific Tides: An Account of the Habits and Habitats of Some Five Hundred of the Common, Conspicuous Seashore Invertebrates of the Pacific Coast Between Sitka, Alaska, and Northern Mexico". Prior to Ricketts' work, the standard descriptive text of intertidal species of the Pacific was ''Seashore Animals of the Pacific Coast'' jointly coauthored by Myrtle E. Johnson and Harry James Snook, published in 1927 (reprinted 1935, 1952, 1967, 1980). ''Between Pacific Tides'' was out of print from 1942 to 1948, but it has since been revised and updated to keep it current, and is now in its fifth edition with the size increasing around twenty percent from the original. Updated and expanded sections have been added since the original edition was published, including: Jo ...

Galápagos Islands
The Galápagos Islands (Spanish: , , ) are an archipelago of volcanic islands. They are distributed on each side of the equator in the Pacific Ocean, surrounding the centre of the Western Hemisphere, and are part of the Republic of Ecuador. Located west of continental Ecuador, the islands are known for their large number of endemic species that were studied by Charles Darwin during the second voyage of HMS ''Beagle''. His observations and collections contributed to the inception of Darwin's theory of evolution by means of natural selection. The Galápagos Islands and their surrounding waters form the Galápagos Province of Ecuador, the Galápagos National Park, and the Galápagos Marine Reserve. The principal language on the islands is Spanish. The islands have a population of slightly over 25,000. The first recorded visit to the islands happened by chance in 1535, when Fray Tomás de Berlanga, the Bishop of Panamá, was surprised to find this undiscovered land on a vo ...
