Gratiola Quartermaniae
''Gratiola quartermaniae'', commonly known as the limestone hedge-hyssop, is a species of flowering plant in the plantain family. It is native to eastern North America. This species has a highly fragmented range. It is most common in the Interior Low Plateaus of Alabama and Tennessee. There are disjunct populations in the Edwards Plateau of Texas, northern Illinois, the Pennyroyal Plain of Kentucky, and to southern Ontario. In each of these wide-ranging locations it is found on areas of pooling water over flat limestone outcrops, in habitats such as cedar glades and alvars. It is likely that this newly described species is more widespread than is currently realized. Due to its highly scattered range and restricted habitat, as well as the threat of habitat destruction Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plantaginaceae
Plantaginaceae, the plantain family, is a large, diverse family of flowering plants in the order Lamiales that includes common flowers such as snapdragon and foxglove. It is unrelated to the banana-like fruit also called "plantain." In older classifications, Plantaginaceae was the only family of the order Plantaginales, but numerous phylogenetic studies, summarized by the Angiosperm Phylogeny Group, have demonstrated that this taxon should be included within Lamiales. Overview The plantain family as traditionally circumscribed consisted of only three genera: ''Bougueria'', ''Littorella'', and ''Plantago''. However phylogenetic research has indicated that Plantaginaceae ''sensu stricto'' (in the strict sense) were nested within Scrophulariaceae (but forming a group that did not include the type genus of that family, ''Scrophularia''). Although Veronicaceae (1782) is the oldest family name for this group, Plantaginaceae (1789) is a conserved name under the International Code of B ...

Interior Low Plateaus
The Interior Low Plateaus are a physiographic region in eastern United States. It consists of a diverse landscape that extends from north Alabama across central Tennessee and Kentucky into southern Illinois, Indiana, and Ohio. Its natural communities are a matrix of temperate forests, woodlands, and prairies. Setting This is a region of rolling plains and eroded plateaus, with a humid subtropical climate in the south and humid continental climate in the north. It is notable for its extensive karst limestone, which comprise the caves at Mammoth Cave National Park. This region includes a portion of what the U.S. Forest service calls the "Central Hardwood Forest". The region extends from southern Ohio, Indiana and Illinois through Tennessee and central Kentucky and into northern Alabama. Nearly 65% of Kentucky's territory is within the Interior Low Plateaus region, which encompasses an area from the western Appalachian Plateaus to the Tennessee River. It includes the Kentucky Blueg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edwards Plateau
The Edwards Plateau is a geographic region at the crossroads of Central Texas, Central, South Texas, South, and West Texas. It is bounded by the Balcones Fault to the south and east, the Llano Uplift and the Llano Estacado to the north, and the Pecos River and Chihuahuan Desert to the west. San Angelo, Texas, San Angelo, Austin, Texas, Austin, San Antonio, and Del Rio, Texas, Del Rio roughly outline the area. The southeast portion of the plateau is known as the Texas Hill Country. Natural history The bedrock consists primarily of limestone, with elevations ranging between 100 and 3000 ft. Caves are numerous. The landscape of the plateau is mostly savanna scattered with trees. It mostly lacks deep soil suitable for farming, though the soil type is fertile mollisol, so some cotton, grain sorghum, and oats are grown. For the most part, though, the thin soil and rough terrain areas are primarily grazing regions, with cattle, sheep, and goats (Angora goat, Angora and meat ty ...

Pennyroyal Plain
The Pennyroyal Plateau or Pennyroyal Region, often spelled Pennyrile, is a large physiographic region of Kentucky that features rolling hills, caves, and karst topography in general. It is named for a wild mint that grows in the area. It is also called the "Mississippian Plateau," for the Mississippian geologic age in which it was formed. The Pennyroyal is bordered by the Pottsville Escarpment in the east. The Pottsville Escarpment is the transition zone from the central part of Kentucky to the higher and geologically younger Cumberland Plateau in the eastern part of the state. The Pennyroyal is bordered on the north by Muldraugh Hill, the geological escarpment that forms the transition from the geologically older Bluegrass to the Pennyroyal. This is a series of knobs and ridges based on hard siltstones. The Pennyroyal is bordered on the west by the younger Jackson Purchase. The Pennyroyal is often thought by non-geologists to include the West Kentucky Coal Field of Pennsyl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cedar Glades
A calcareous glade is a type of ecological community (ecology), community that is found in the central Eastern United States. Calcareous glade (geography), glades occur where bedrock such as limestone occurs near or at the surface, and have very shallow and little soil development. Due to the shallow soil and the extreme conditions created by it, trees are often unable to grow in the glades. This creates a habitat that is usually sunny, dry, and hot. Calcareous glade vegetation is more similar to that of a desert habitat than a grassland, being dominated by small spring annuals with occasional geophyte, geophytic or succulent perennial plant, perennials. The usage of the words "glades" and "barrens" to describe dry, rocky communities in the United States is not uniform, and the terms are often used interchangeably. Calcareous glade communities can intergrade with dry rocky prairies, particularly in sloping habitats. Due to their unsuitability for agriculture, glade communities hav ...

Alvars
The Alvars ( ta, ஆழ்வார், Āḻvār, translit-std=ISO, lit=The Immersed) were the Tamil poet-saints of South India who espoused ''bhakti'' (devotion) to the Hindu preserver deity Vishnu, in their songs of longing, ecstasy, and service. They are venerated in Vaishnavism, which regards Vishnu as the Ultimate Reality. Many modern academics place the lifetime of the Alvars between the 5th century and 10th century CE. Traditionally, the Alvars are considered to have lived between and . Orthodoxy posits the number of Alvars as ten, though there are other references that include Andal and Madhurakavi Alvar, making the number 12. Andal is the only female Alvar among the 12. Together with the contemporary 63 Shaivite Nayanars, they are among the most important saints from Tamil Nadu. The devotional outpourings of the Alvars, composed during the early medieval period of Tamil history, were the catalysts behind the Bhakti Movement through their hymns of worship to Vish ...

Habitat Destruction
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Flora Of The Southeastern United States
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or '' skin flora''. 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) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de Phy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
