Lost Pines Forest
The Lost Pines Forest is a belt of loblolly pines (''Pinus taeda'') in the U.S. state of Texas, near the town of Bastrop, Texas, Bastrop. The stand of pines is unique in Texas because it is a disjunct distribution, disjunct population of trees that is more than separated from, and yet closely genetically related to, the vast expanse of pine trees of the Piney Woods region that covers parts of Texas, Arkansas, Louisiana, and Oklahoma. History The forest is thought to have originated as part of a much larger pine forest that shrank in size during the last glacial period of the Pleistocene, Pleistocene era. It was first described by early Spanish explorer Domingo Terán de los Ríos in his expedition along the Colorado River (Texas), Colorado River in 1691 and later by Stephen F. Austin and other settlers drawn to the area by the land grants awarded by the Mexican government. The Bastrop Steam Mill Company began lumbering in the Lost Pines in 1838, followed by Higgins Mill in 1840. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pinus Taeda
''Pinus taeda'', commonly known as loblolly pine, is one of several pines native to the Southeastern United States, from East Texas to Florida, and north to southern New Jersey. The wood industry classifies the species as a southern yellow pine. U.S. Forest Service surveys found that loblolly pine is the second-most common species of tree in the United States, after red maple. For its timber, the pine species is regarded as the most commercially important tree in the Southeastern U.S. The common name loblolly is given because the pine species is found mostly in lowlands and swampy areas. Loblolly pine is the first among over 100 species of ''Pinus'' to have its complete genome sequenced. As of March 2014, it was the organism having the largest sequenced genome size. Its genome, with 22 billion base pairs, is seven times larger than that of humans. As of 2018, assembly of the axolotl genome (32Gb) displaced loblolly pine as the largest assembled genome. The loblolly pine was se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colorado River (Texas)
The Colorado River is an approximately long river in the U.S. state of Texas. It is the 18th longest river in the United States and the longest river with both its source and its mouth within Texas. Its drainage basin and some of its usually dry tributaries extend into New Mexico. It flows generally southeast from Dawson County through Ballinger, Marble Falls, Lago Vista, Austin, Bastrop, Smithville, La Grange, Columbus, Wharton, and Bay City, before emptying into the Gulf of Mexico at Matagorda Bay. Course The Colorado River originates south of Lubbock, on the Llano Estacado near Lamesa. It flows generally southeast out of the Llano Estacado and through the Texas Hill Country, then through several reservoirs including Lake J.B. Thomas, E.V. Spence Reservoir, and O.H. Ivie Lake. The river flows through several more reservoirs before reaching Austin, including Lake Buchanan, Inks Lake, Lake Lyndon B. Johnson (commonly referred to as Lake LBJ), and Lake Tra ...

Bastrop County Complex Fire
The Bastrop County Complex fire was a conflagration that engulfed parts of Bastrop County, Texas, in September and October 2011. The wildfire was the costliest and most destructive wildfire in Texas history and among the costliest in U.S. history, destroying 1,696 structures and causing an estimated $350 million in insured property damage. An exceptional drought, accompanied by record-high temperatures, affected Texas for much of 2011. Vegetation consequently became severely parched throughout the state, and over the year an unprecedented amount of land in the state was burned by numerous wildfires. In early September 2011, the presence of Tropical Storm Lee to the east produced strong northerly winds over the state, exacerbating the preexisting dry weather to produce critical fire conditions. On the afternoon of September 4, 2011, three separate fires ignited in the wildland–urban interface east of Bastrop, Texas, after strong winds caused by the nea ...

Population Bottleneck
A population bottleneck or genetic bottleneck is a sharp reduction in the size of a population due to environmental events such as famines, earthquakes, floods, fires, disease, and droughts; or human activities such as specicide, widespread violence or intentional culling, and human population planning. Such events can reduce the variation in the gene pool of a population; thereafter, a smaller population, with a smaller genetic diversity, remains to pass on genes to future generations of offspring through sexual reproduction. Genetic diversity remains lower, increasing only when gene flow from another population occurs or very slowly increasing with time as random mutations occur. This results in a reduction in the robustness of the population and in its ability to adapt to and survive selecting environmental changes, such as climate change or a shift in available resources. Alternatively, if survivors of the bottleneck are the individuals with the greatest genetic fitness, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climate Change
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing ...

Mississippi River
The Mississippi River is the second-longest river and chief river of the second-largest drainage system in North America, second only to the Hudson Bay drainage system. From its traditional source of Lake Itasca in northern Minnesota, it flows generally south for to the Mississippi River Delta in the Gulf of Mexico. With its many tributaries, the Mississippi's watershed drains all or parts of 32 U.S. states and two Canadian provinces between the Rocky and Appalachian mountains. The main stem is entirely within the United States; the total drainage basin is , of which only about one percent is in Canada. The Mississippi ranks as the thirteenth-largest river by discharge in the world. The river either borders or passes through the states of Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana. Native Americans have lived along the Mississippi River and its tributaries for thousands of years. Most were hunter-gathere ...

East Texas
East Texas is a broadly defined cultural, geographic, and ecological region in the eastern part of the U.S. state of Texas that comprises most of 41 counties. It is primarily divided into Northeast and Southeast Texas. Most of the region consists of the Piney Woods ecoregion. East Texas can sometimes be defined only as the Piney Woods. At the fringes, towards Central Texas, the forests expand outward toward sparser trees and eventually into open plains. According to the '' Handbook of Texas'', the East Texas area "may be separated from the rest of Texas roughly by a line extending from the Red River in north-central Lamar County southwestward to east-central Limestone County and then southeastward towards eastern Galveston Bay". Most sources separate the Gulf Coast area into a separate region. Another popular, somewhat simpler, definition defines East Texas as the region between the Trinity River, north and east of Houston (or sometimes Interstate 45, when defining gener ...

Buescher State Park
Buescher State Park is a state park located just north of Smithville, Texas. The park consists of of public land donated to the state by Mr. Emil and Mrs. Elizabeth Buescher, as well as the City of Smithville. History Between the years 1933 and 1936, Mr. Emil and Mrs. Elizabeth Buescher deeded of land to the State of Texas. After Emil Buescher's death, his heirs donated more. The rest of the parkland was acquired from the city of Smithville. Companies 1805 and 1811 of the Civilian Conservation Corps built many of the park facilities between 1933 and 1939 using native stone to better blend with the surrounding landscape. When it opened in 1940, the park was . In 1967, the Texas Legislature transferred to The University of Texas M. D. Anderson Cancer Center for use as a research facility, currently known as the Virginia Harris Cockrell Cancer Research Center at The University of Texas MD Anderson Cancer Center (Science Park). In May 1957, Buescher State Park was selected t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bastrop State Park
Bastrop State Park is a state park in Bastrop County, Texas, United States. The park was established in 1933 and consists of stands of loblolly pines mixed with post oak and junipers. History Pre-foundation The Spanish travel route known as El Camino Real traversed through the area and aided in the early colonization of Texas in the 1700s. The city of Bastrop, Texas, established in 1832, depended on the natural resources of the area for regional growth; Bastrop's timber harvest from pines fueled construction in Austin, San Antonio, and northern Mexico. Long before the park's construction began, citizens of Bastrop and Smithville recognized that the land was worth preserving and kept it as an informal recreational area supervised by a local hunting and fishing organization. The land had also served unsuccessfully as a private resort area. Construction In the early 1930s, during the peak of the Great Depression, US President Franklin D. Roosevelt created a public work ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stephen F
Stephen or Steven is a common English first name. It is particularly significant to Christians, as it belonged to Saint Stephen ( grc-gre, Στέφανος ), an early disciple and deacon who, according to the Book of Acts, was stoned to death; he is widely regarded as the first martyr (or " protomartyr") of the Christian Church. In English, Stephen is most commonly pronounced as ' (). The name, in both the forms Stephen and Steven, is often shortened to Steve or Stevie. The spelling as Stephen can also be pronounced which is from the Greek original version, Stephanos. In English, the female version of the name is Stephanie. Many surnames are derived from the first name, including Stephens, Stevens, Stephenson, and Stevenson, all of which mean "Stephen's (son)".

Domingo Terán De Los Ríos
Domingo Terán de los Ríos served as the first governor of Texas from 1691 to 1692. He also governed Coahuila, in the modern-day Mexico. Previous service Terán served the Spanish crown in Peru for two decades. He came to Mexico in 1681 as a deputy of the consulado of Sevilla. He was appointed governor of the province of Sonora y Sinaloa in 1686, and served in that position for approximately five years. As governor, he successfully developed a mining industry and pacified the Native Americans in that area. Coahuila and Tejas Terán was appointed governor on January 23, 1691, by Viceroy Gaspar de la Cerda, 8th Count of Galve. He was appointed to oversee the administration of Coahuila, Texas and adjacent regions. His role as governor was to set up seven missions among the Tejas Indians; to seek and remove any foreigners that may have settled in Spanish territory; and to catalog the land, the natural resources, and the peoples of the area.
