Gopher Frog
The gopher frog (''Lithobates capito'') is a species of frog in the family Ranidae, endemic to the south-eastern United States. It primarily inhabits the threatened sandhill communities, flatwoods, and scrub in the Atlantic coastal plain, where it is usually found near ponds. Subspecies Its two subspecies include the Carolina gopher frog (''L. c. capito''), and Florida gopher frog (''L. c. aesopus''). The dusky gopher frog ''(L. sevosus)'', also known as the Mississippi gopher frog, had previously been considered a subspecies, but was elevated to species status in 2001. Range Gopher frogs occur along the Atlantic seaboard of the United States from southern North Carolina to peninsular Florida. The gopher frog's range extends west along the Gulf Coast to the Tombigbee River in Alabama. The Florida gopher frog is restricted to peninsular Florida. Today, gopher frogs' distribution is patchy, owing greatly to loss of longleaf pine forest communities. Ecology Within the flatw ...

John Eatton Le Conte
John Eatton Le Conte Jr. (sometimes John Eatton LeConte or John Eaton Leconte) (February 22, 1784 – November 21, 1860) was an American natural history, naturalist. He was born near Shrewsbury, New Jersey, Shrewsbury, New Jersey, the son of John Eatton Le Conte and Jane Sloane Le Conte. He graduated from Columbia College of Columbia University, Columbia College, where he showed an interest in science and was taught natural history by David Hosack, founder of Elgin Botanical Garden. John Le Conte's older brother Louis Le Conte, Louis inherited the family plantation, Woodmanston, near Midway, Georgia, Midway in Georgia (U.S. state), Georgia. Although John Le Conte usually lived in New York City, New York or New England, he spent his winters at Woodmanston. He suffered from rheumatism, and possibly other ailments, for most of his adult life. In April 1818 Le Conte was appointed captain in the United States Army Corps of Topographical Engineers. His early assignments included ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sand Pine
''Pinus clausa'' is a species of pine endemic to the Southeastern United States. Its common names include sand pine, Florida spruce pine, and scrub pine. Distribution The tree is found in two separate locations, one across central peninsular Florida, and the other along the western Florida panhandle coast into the Alabama coast. There is a range gap of about between the populations (from the Ochlockonee River to Cedar Key). The sand pines of the Florida peninsula and of the Florida panhandle coast differ enough to be classified into two varieties or races, ''Pinus clausa'' var. ''clausa'' ("Ocala"), on the peninsula, and ''P. clausa'' var. ''immuginata'' ("Choctawhatchee"), along the panhandle coast. While most panhandle sand pines (var. ''immuginata'') have non-serotinous, or open, cones, most of the peninsular sand pines (var. ''clausa'') have serotinous, or closed, cones. Sand pine is largely confined to the very infertile, excessively well-drained, sandy habitat of Florid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibians Described In 2006
Amphibians are ectothermic, anamniotic, four-limbed vertebrate animals that constitute the class Amphibia. In its broadest sense, it is a paraphyletic group encompassing all tetrapods, but excluding the amniotes (tetrapods with an amniotic membrane, such as modern reptiles, birds and mammals). All extant (living) amphibians belong to the monophyletic subclass Lissamphibia, with three living orders: Anura (frogs and toads), Urodela (salamanders), and Gymnophiona (caecilians). Evolved to be mostly semiaquatic, amphibians have adapted to inhabit a wide variety of habitats, with most species living in freshwater, wetland or terrestrial ecosystems (such as riparian woodland, fossorial and even arboreal habitats). Their life cycle typically starts out as aquatic larvae with gills known as tadpoles, but some species have developed behavioural adaptations to bypass this. Young amphibians generally undergo metamorphosis from an aquatic larval form with gills to an air-breathing a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lithobates
''Lithobates'', commonly known as the bullfrogs, is a genus of true frogs, of the family Ranidae. The name is derived from '' litho-'' (stone) and the Greek ' (, one that treads), meaning one that treads on rock, or rock climber. As presently defined, it includes many of eastern North America's most familiar aquatic frog species, including the American bullfrog, green frog, and the leopard frogs. Systematics The name was defined by Hillis and Wilcox (2005) for a subgenus of four Central and South American frogs within the genus ''Rana''. The subgenus was subsequently expanded to seven species in Central and South America in a systematic revision of the genus ''Rana''. The name was previously used by Frost ''et al.'' as a separate genus of ranid frogs that included most of the North American frogs traditionally included in the genus ''Rana'',Frost, Darrel R. (2006): Amphibian Species of the World Version 3 Petropedetidae Noble, 1931 American Museum of Natural History, New Yor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Controlled Burn
A controlled burn or prescribed burn (Rx burn) is the practice of intentionally setting a fire to change the assemblage of vegetation and decaying material in a landscape. The purpose could be for forest management, ecological restoration, land clearing or wildfire fuel management. Controlled burns may also be referred to as hazard reduction burning'', ''backfire'', ''swailing or a burn-off. Controlled burns are conducted during the cooler months to reduce fuel buildup and decrease the likelihood of more dangerous, hotter fires. Controlled burning stimulates the germination of some trees and reveals soil mineral layers which increases seedling vitality. In grasslands, controlled burns shift the species assemblage to primarily native grassland species. Some seeds, such as those of lodgepole pine, sequoia and many chaparral shrubs are pyriscent, meaning heat from fire causes the cone or woody husk to open and disperse seeds. Fire is a natural part of both forest and grass ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire Fighting
Firefighting is a profession aimed at controlling and extinguishing fire. A person who engages in firefighting is known as a firefighter or fireman. Firefighters typically undergo a high degree of technical training. This involves structural firefighting and wildland firefighting. Specialized training includes aircraft firefighting, shipboard firefighting, aerial firefighting, maritime firefighting, and proximity firefighting. Firefighting is a dangerous profession due to the toxic environment created by combustible materials, with major risks being smoke, oxygen deficiency, elevated temperatures, poisonous atmospheres, and violent air flows. To combat some of these risks, firefighters carry self-contained breathing apparatus. Additional hazards include falling (accident), falls – a constant peril while navigating unfamiliar layouts or confined spaces amid shifting debris under limited visibility – and structural collapse that can exacerbate the problems encountered in a toxi ...

Construction
Construction are processes involved in delivering buildings, infrastructure, industrial facilities, and associated activities through to the end of their life. It typically starts with planning, financing, and design that continues until the asset is built and ready for use. Construction also covers repairs and maintenance work, any works to expand, extend and improve the asset, and its eventual demolition, dismantling or wikt:decommission, decommissioning. The construction industry contributes significantly to many countries' gross domestic products (Gross domestic product, GDP). Global expenditure on construction activities was about $4 trillion in 2012. In 2022, expenditure on the construction industry exceeded $11 trillion a year, equivalent to about 13 percent of global Gross domestic product, GDP. This spending was forecasted to rise to around $14.8 trillion in 2030. The construction industry promotes economic development and brings many non-monetary benefits to many cou ...

Gopher Tortoise
The gopher tortoise (''Gopherus polyphemus'') is a species of tortoise in the family Testudinidae. The species is native to the southeastern United States. The gopher tortoise is seen as a keystone species because it digs burrows that provide shelter for at least 360 other animal species. ''G. polyphemus'' is threatened by predation and habitat destruction. Habitat degradation is the primary reason that the gopher tortoise is listed as vulnerable on the IUCN Red List, but they are considered threatened in some states while they are endangered in others. The gopher tortoise is a representative of the genus ''Gopherus'', which contains the only tortoises native to North America. The gopher tortoise is the state reptile of Georgia and the state tortoise of Florida. Etymology Tortoises of the genus ''Gopherus'' are so named because of some species' habit of digging large, deep burrows like those of gophers. The specific name, ''polyphemus'', refers to the cave-dwelling giant, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hammock (ecology)
Hammock is a term used in the southeastern United States for stands of trees, usually hardwood, that form an ecological island in a contrasting ecosystem. Hammocks grow on elevated areas, often just a few inches high, surrounded by wetlands that are too wet to support them. The term ''hammock'' is also applied to stands of hardwood trees growing on slopes between wetlands and drier uplands supporting a mixed or coniferous forest. Types of hammocks found in the United States include tropical hardwood hammocks, temperate hardwood hammocks, and maritime or coastal hammocks. Hammocks are also often classified as hydric (wet soil), mesic (moist soil) or xeric (dry soil). The types are not exclusive, but often grade into each other. Unlike many ecosystems of the coastal plain of the southeastern United States, hammocks are not tolerant of fire. Hammocks tend to occur in locations where fire is not common, or where there is some protection from fire in neighboring ecosystems. Hammocks ...

Quercus Laevis
''Quercus laevis'', the turkey oak, is a member of the red oak group of oaks. It is native to the southeastern United States. The name turkey oak derives from the resemblance of the leaves to a turkey's foot. A Turkish and southern European species '' Quercus cerris'' is also commonly referred to as Turkey oak, so ''Quercus laevis'' is sometimes referred to as American turkey oak to distinguish it from the European species. Description ''Quercus laevis'' is a small tree, sometimes shrubby, typically only tall, though occasionally reaching . The leaves are variable in size, mostly long but occasionally just or as much as long. They have 3–7 slender lobes, deeply incised between the lobes, each lobe with 1–3 bristle teeth at the tip. The leaves turn red in Autumn. The acorns are about long, and, like other red oaks, take 18 months to mature. Distribution and habitat Turkey oak occurs on the coastal plain from Virginia south to southwestern Florida, and west to so ...
