Natural History Of The California Chaparral And Woodlands
Nature is an inherent character or constitution, particularly of the ecosphere or the universe as a whole. In this general sense nature refers to the laws, elements and phenomena of the physical world, including life. Although humans are part of nature, human activity or humans as a whole are often described as at times at odds, or outright separate and even superior to nature. During the advent of modern scientific method in the last several centuries, nature became the passive reality, organized and moved by divine laws. With the Industrial Revolution, nature increasingly became seen as the part of reality deprived from intentional intervention: it was hence considered as sacred by some traditions ( Rousseau, American transcendentalism) or a mere decorum for divine providence or human history (Hegel, Marx). However, a vitalist vision of nature, closer to the pre-Socratic one, got reborn at the same time, especially after Charles Darwin. Within the various uses of the word ...

Flora Of Baja California
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) wa ...

Flora Of California
California native plants are plants that existed in California prior to the arrival of European colonialism, European explorers and colonists in the late 18th century. California includes parts of at least three Phytochorion, phytochoria. The largest is the California Floristic Province, a geographical area that covers most of California, portions of neighboring Oregon, Nevada, and Baja California, and is regarded as a "world hotspot" of biodiversity. Introduction In 1993, ''The Jepson Manual'' estimated that California was home to 4,693 native species and 1,169 native subspecies or varieties, including 1,416 endemic species. A 2001 study by the California Native Plant Society estimated 6,300 native plants. These estimates continue to change over time. Of California's total plant population, 2,153 species, subspecies, and varieties are endemism, endemic and native to California alone, according to the 1993 Jepson Manual study. This botanical diversity stems not only from the si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Loam
Loam (in geology and soil science) is soil composed mostly of sand (particle size > ), silt (particle size > ), and a smaller amount of clay (particle size < ). By weight, its mineral composition is about 40–40–20% concentration of sand–silt–clay, respectively. These proportions can vary to a degree, however, and result in different types of loam soils: sandy loam, silty loam, clay loam, sandy clay loam, silty clay loam, and loam. In the USDA, United States Department of Agriculture, soil texture, textural classification triangle, the only soil that is not predominantly sand, silt, or clay is called "loam". Loam soils generally contain more nutrients, moisture, and humus than sandy soils, have better drainage and infiltration of water and air than silt- and clay-rich soils, and are easier to tillage, till than clay soils. In fact, the primary definition of loam in most dictionaries is soils containing hu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Igneous Rock
Igneous rock ( ), or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rocks are formed through the cooling and solidification of magma or lava. The magma can be derived from partial melts of existing rocks in either a planet's mantle or crust. Typically, the melting is caused by one or more of three processes: an increase in temperature, a decrease in pressure, or a change in composition. Solidification into rock occurs either below the surface as intrusive rocks or on the surface as extrusive rocks. Igneous rock may form with crystallization to form granular, crystalline rocks, or without crystallization to form natural glasses. Igneous rocks occur in a wide range of geological settings: shields, platforms, orogens, basins, large igneous provinces, extended crust and oceanic crust. Geological significance Igneous and metamorphic rocks make up 90–95% of the top of the Earth's crust by volume. Igneous rock ...

Lakeside was founded in 1886 when 6,600 acres of land surrounding the naturally occurring Lindo Lake were purchased by the El Cajon Valley Land Company, who immediately began to promote the new land as a town and built an 80-room Victorian-style inn, the Lakeside Hotel, at a cost of $50,000 (approximately $1,220,000 today).
