Florida Scrub Lizard
The Florida scrub lizard (''Sceloporus woodi'') is a species of lizard in the family Phrynosomatidae. The species is endemic to Florida, the United States. Etymology The specific name, ''woodi'', is in honor of taxidermist Nelson R. Wood (died 1920) of the Smithsonian Institution who collected the holotype.Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii + 296 pp. . (''Sceloporus woodi'', p. 289). Description The adult Florida scrub lizard is about 5 inches (13 cm) in total length (including tail). It is gray or brownish with a longitudinal brown stripe down each side of the body. The male has turquoise patches on the throat and belly. The female usually lacks the throat patches, but may have lighter patches on the abdomen. Enge KM, Branch LCbr>"Florida scrub lizard (''Sceloporus woodi'' )".Document WEC 139.

Leonhard Stejneger
Leonhard Hess Stejneger (30 October 1851 – 28 February 1943) was a Norwegian-born American ornithologist, herpetologist and zoologist. Stejneger specialized in vertebrate natural history studies. He gained his greatest reputation with reptiles and amphibians. Wetmore, Alexander (1945). "Leonhard Hess Stejneger (1851-1943)". ''Biographical Memoir. Nat. Acad. Sci.'' 24: 145-195PDF/ref> Early life and family Stejneger was born in Bergen, Norway. His father was Peter Stamer Steineger, a merchant and auditor; his mother was Ingeborg Catharine (née Hess). Leonhard was the eldest of seven children. His sister Agnes Steineger was a Norwegian artist. Until 1880, the Steineger family had been one of the wealthy families in Bergen; at that time business reverses led to the father declaring bankruptcy. Stejneger attended the Smith Theological School in Bergen from 1859 to 1860, and Bergen Latin School until 1869. His interests in zoology developed early. By age sixteen he had a print ...

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ...

Lake Wales Ridge
The Lake Wales Ridge, sometimes referred to as the Mid-Florida Ridge,Eastern States Archaeological Federation. ''Archaeology of Eastern North America, Volume 11'', p. 54 is a sand ridge running for about 150 miles south to north in Central Florida. Clearly viewable from satellite, the white sands of the ridge are located in Highlands County and Polk County, and also extend north into Osceola, Orange, and Lake Counties. It is named for the city of Lake Wales, roughly at the midpoint of the ridge. The highest point of the ridge is Sugarloaf Mountain, which at is also the highest natural point in peninsular Florida. (The highest point of land, at , is a manmade mining tank west of Bartow.) Iron Mountain, the location of Bok Tower, marks another well known high point on the ridge, attaining an elevation of . A northern unconnected extension of the Lake Wales Ridge exists in western Putnam County near the town of Grandin. Origins Florida's ancient sand islands stretch for over 100 ...

Ocala National Forest
The Ocala National Forest ls the second largest nationally protected forest in the U.S. State of Florida. It covers of northern Florida. It is located three miles (5 km) east of Ocala and southeast of Gainesville. The Ocala National Forest, established in 1908, is the oldest national forest east of the Mississippi River and the southernmost national forest in the continental U.S. The word ''Ocala'' is thought to be a derivative of a Timucuan term meaning "fair land" or "big hammock". The forest is headquartered in Tallahassee, as are all three National Forests in Florida, but there are local ranger district offices located in Silver Springs and Umatilla. Geography and ecology The Ocala National Forest lies between the Ocklawaha and St. Johns rivers in Central Florida. In descending order of land area, it is located in parts of Marion, Lake, and Putnam counties. The Ocala National Forest is in the southeastern conifer forests and the Florida sand pine scrub ecore ...

Gulf Coast Of The United States
The Gulf Coast of the United States, also known as the Gulf South, is the coastline along the Southern United States where they meet the Gulf of Mexico. The coastal states that have a shoreline on the Gulf of Mexico are Texas, Louisiana, Mississippi, Alabama, and Florida, and these are known as the ''Gulf States''. The economy of the Gulf Coast area is dominated by industries related to energy, petrochemicals, fishing, aerospace, agriculture, and tourism. The large cities of the region are (from west to east) Brownsville, Corpus Christi, Houston, Galveston, Beaumont, Lake Charles, Lafayette, Baton Rouge, New Orleans, Gulfport, Biloxi, Mobile, Pensacola, Navarre, St. Petersburg, and Tampa. All are the centers or major cities of their respective metropolitan areas and many of which contain large ports. Geography The Gulf Coast is made of many inlets, bays, and lagoons. The coast is intersected by numerous rivers, the largest of which is the Mississippi River. Much of the l ...

Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N. Scientific explorations of the A ...

Disjunct Distribution
In biology, a taxon with a disjunct distribution is one that has two or more groups that are related but considerably separated from each other geographically. The causes are varied and might demonstrate either the expansion or contraction of a species' range. Range fragmentation Also called range fragmentation, disjunct distributions may be caused by changes in the environment, such as mountain building and continental drift or rising sea levels; it may also be due to an organism expanding its range into new areas, by such means as rafting, or other animals transporting an organism to a new location (plant seeds consumed by birds and animals can be moved to new locations during bird or animal migrations, and those seeds can be deposited in new locations in fecal matter). Other conditions that can produce disjunct distributions include: flooding, or changes in wind, stream, and current flows, plus others such as anthropogenic introduction of alien introduced species either acciden ...

Ectotherm
An ectotherm (from the Greek () "outside" and () "heat") is an organism in which internal physiological sources of heat are of relatively small or of quite negligible importance in controlling body temperature.Davenport, John. Animal Life at Low Temperature. Publisher: Springer 1991. Such organisms (for example frogs) rely on environmental heat sources, which permit them to operate at very economical metabolic rates. Some of these animals live in environments where temperatures are practically constant, as is typical of regions of the abyssal ocean and hence can be regarded as homeothermic ectotherms. In contrast, in places where temperature varies so widely as to limit the physiological activities of other kinds of ectotherms, many species habitually seek out external sources of heat or shelter from heat; for example, many reptiles regulate their body temperature by basking in the sun, or seeking shade when necessary in addition to a whole host of other behavioral thermo ...

Citrus
''Citrus'' is a genus of flowering plant, flowering trees and shrubs in the rue family, Rutaceae. Plants in the genus produce citrus fruits, including important crops such as Orange (fruit), oranges, Lemon, lemons, grapefruits, pomelos, and lime (fruit), limes. The genus ''Citrus'' is native to South Asia, East Asia, Southeast Asia, Melanesia, and Australia (continent), Australia. Various citrus species have been used and domesticated by indigenous cultures in these areas since ancient times. From there its cultivation spread into Micronesia and Polynesia by the Austronesian expansion (c. 3000–1500 BCE); and to the Middle East and the Mediterranean (c. 1200 BCE) via the incense trade route, and onwards to Europe and the Americas. History Citrus plants are native to subtropical and tropical regions of Asia, Island Southeast Asia, Near Oceania, and northeastern Australia. Domestication of citrus species involved much hybridization and introgression, leaving much uncertainty ab ...

Flatwoods
Flatwoods, pineywoods, pine savannas and longleaf pine-wiregrass ecosystem are terms that refer to an ecological community in the southeastern coastal plain of North America. Flatwoods are an ecosystem maintained by wildfire or prescribed fire and are dominated by longleaf pine (''Pinus palustris''), and slash pine (''Pinus elliotii'') in the tree canopy and saw palmetto (''Serenoa repens''), gallberry (''Ilex glabra'') and other flammable evergreen shrubs in the understory, along with a high diversity of herb species.Platt, W.J. 1999. Southeastern pine savannas. In: Anderson, R.C., Fralish, J.S. & Baskin, J. (eds.) The savanna, barren, and rock outcrop communities of North America, pp. 23- 51.

Sandhill
A sandhill is a type of ecological community or xeric wildfire-maintained ecosystem. It is not the same as a sand dune. It features very short fire return intervals, one to five years. Without fire, sandhills undergo ecological succession and become more oak dominated. Entisols are the typical sandhill soil, deep well-drained and nutrient poor. In Florida, sandhills receive cm of rainfall per year, just like the more hydric ecosystems surrounding them. Sandhills are xeric because they have poor water holding capacity. Dominant vegetation includes longleaf pine (''Pinus palustris''), American turkey oak (''Quercus laevis''), and wiregrass (''Aristida stricta''). A number of rare animals are typical of this habitat including the gopher tortoise (''Gopherus polyphemus''), red-cockaded woodpecker (''Picoides borealis''), Sherman's fox squirrel ('' Sciurus niger shermani''), and striped newt (''Notophthalmus perstriatus''). Invasive species that are a problem on sandhills include Co ...

Ecotone
An ecotone is a transition area between two biological communities, where two communities meet and integrate. It may be narrow or wide, and it may be local (the zone between a field and forest) or regional (the transition between forest and grassland ecosystems). An ecotone may appear on the ground as a gradual blending of the two communities across a broad area, or it may manifest itself as a sharp boundary line. Etymology The word ''ecotone'' was coined by Alfred Russel Wallace, who first observed the abrupt boundary between two biomes in 1859. It is formed as a combination of ''ecology'' plus ''-tone'', from the Greek ''tonos'' or tension – in other words, a place where ecologies are in tension. Features There are several distinguishing features of an ecotone. First, an ecotone can have a sharp vegetation transition, with a distinct line between two communities. For example, a change in colors of grasses or plant life can indicate an ecotone. Second, a change in physiogn ...
