List Of National Natural Landmarks
The National Natural Landmarks (NNL) Program recognizes and encourages the conservation of outstanding examples of the natural history of the United States. It is the only national natural areas program that identifies and recognizes the best examples of biological and geological features in both public and private ownership. The program was established on May 18, 1962, by United States Secretary of the Interior Stewart Udall. The program aims to encourage and support voluntary preservation of sites that illustrate the geological and ecological history of the United States. It also hopes to strengthen the public's appreciation of the country's natural heritage. As of January 2021, 602 sites have been added to the National Registry of Natural Landmarks. The registry includes nationally significant geological and ecological features in 48 states, American Samoa, Guam, Puerto Rico, and the U.S. Virgin Islands. The National Park Service administers the NNL Program and if reques ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Topography
Topography is the study of the forms and features of land surfaces. The topography of an area may refer to the land forms and features themselves, or a description or depiction in maps. Topography is a field of geoscience and planetary science and is concerned with local detail in general, including not only relief, but also natural, artificial, and cultural features such as roads, land boundaries, and buildings. In the United States, topography often means specifically ''relief'', even though the USGS topographic maps record not just elevation contours, but also roads, populated places, structures, land boundaries, and so on. Topography in a narrow sense involves the recording of relief or terrain, the three-dimensional quality of the surface, and the identification of specific landforms; this is also known as geomorphometry. In modern usage, this involves generation of elevation data in digital form (DEM). It is often considered to include the graphic representat ...

Karst
Karst is a topography formed from the dissolution of soluble rocks such as limestone, Dolomite (rock), dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. However, in regions where the dissolved bedrock is covered (perhaps by debris) or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground. The study of ''paleokarst'' (buried karst in the stratigraphic column) is important in petroleum geology because as much as 50% of the world's hydrocarbon reserves are hosted in carbonate rock, and much of this is found in porous karst systems. Etymology The English word ''karst'' was borrowed from German language, German in the late 19th century, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Utuado, Puerto Rico
Utuado () is a town and municipality of Puerto Rico located in the central mountainous region of the island known as the '' Cordillera Central''.

Puerto Rican Parrot
The Puerto Rican amazon (''Amazona vittata''), also known as the Puerto Rican parrot (Puerto Rican Spanish: ''cotorra puertorriqueña'') or ''iguaca'', is the only extant parrot endemic to the archipelago of Puerto Rico, and belongs to the Neotropical genus '' Amazona''. Measuring , the bird is a predominantly green parrot with a red forehead and white rings around the eyes. Its closest relatives are believed to be the Cuban amazon (''Amazona leucocephala'') and the Hispaniolan amazon (''Amazona ventralis''). The Puerto Rican amazon reaches sexual maturity at between three and four years of age. It reproduces once a year and is a cavity nester. Once the female lays eggs she will remain in the nest and continuously incubate them until hatching. The chicks are fed by both parents and will fledge 60 to 65 days after hatching. This parrot's diet is varied and consists of flowers, fruits, leaves, bark and nectar obtained from the forest canopy. The species is the only remaining n ...

Río Abajo State Forest
Rio Abajo State Forest is a forest preserve in Puerto Rico owned by the Department of Natural Resources and one of the 20 state forests in the island. It was designated a National Natural Landmark in 1980 and constitutes an area of 3,590 acres. It consists mostly of subtropical wet and moist karst forest. Mogotes and sinkholes fill the landscape. The forest preserve is located in the municipalities of Arecibo and Utuado. In addition to its ecological value the forest also contains a number of archaeological sites. History Much of the development within the forest area was made by the Civilian Conservation Corps (CCC) during the 20th century. The forest preserve was one of the five designated forests designated in 1943 by the Puerto Rico Reconstruction Administration (Spanish: ''Administración de Reconstrucción de Puerto Rico'') to preserve the remaining forested areas in the island. This forest also protects a large portion of the Arecibo River hydrological basin. The re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bioluminescence
Bioluminescence is the production and emission of light by living organisms. It is a form of chemiluminescence. Bioluminescence occurs widely in marine vertebrates and invertebrates, as well as in some fungi, microorganisms including some bioluminescent bacteria, and terrestrial arthropods such as fireflies. In some animals, the light is bacteriogenic, produced by symbiotic bacteria such as those from the genus '' Vibrio''; in others, it is autogenic, produced by the animals themselves. In a general sense, the principal chemical reaction in bioluminescence involves a light-emitting molecule and an enzyme, generally called luciferin and luciferase, respectively. Because these are generic names, luciferins and luciferases are often distinguished by the species or group, e.g. firefly luciferin. In all characterized cases, the enzyme catalyzes the oxidation of the luciferin. In some species, the luciferase requires other cofactors, such as calcium or magnesium ions, and so ...

Vieques, Puerto Rico
Vieques (; ), officially Isla de Vieques, is an island and municipality of Puerto Rico, in the northeastern Caribbean, part of an island grouping sometimes known as the Spanish Virgin Islands. Vieques is part of the Commonwealth of Puerto Rico, and retains strong influences from 400 years of Spanish presence in the island. Vieques lies about east of the Puerto Rican mainland, and measures about long by wide. Its most populated barrio is the town of Isabel Segunda (sometimes written "Isabel II"), the administrative center located on the northern side of the island. The population of Vieques was 8,249 at the 2020 Census. The island's name is a Spanish spelling of a Taíno word said to mean "small island" or "small land". It also has the nickname ''Isla Nena'', usually translated as "Little Girl Island", alluding to its perception as Puerto Rico's little sister. The island was given this name by the Puerto Rican poet Luis Llorens Torres. During the British colonial period its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mosquito Bay, Bioluminescent Bay, Vieques - Panoramio (3)
Mosquitoes (or mosquitos) are members of a group of almost 3,600 species of small flies within the family Culicidae (from the Latin ''culex'' meaning "gnat"). The word "mosquito" (formed by ''mosca'' and diminutive ''-ito'') is Spanish for "little fly". Mosquitoes have a slender segmented body, one pair of wings, one pair of halteres, three pairs of long hair-like legs, and elongated mouthparts. The mosquito life cycle consists of egg, larva, pupa, and adult stages. Eggs are laid on the water surface; they hatch into motile larvae that feed on aquatic algae and organic material. These larvae are important food sources for many freshwater animals, such as dragonfly nymphs, many fish, and some birds such as ducks. The adult females of most species have tube-like mouthparts (called a proboscis) that can pierce the skin of a host and feed on blood, which contains protein and iron needed to produce eggs. Thousands of mosquito species feed on the blood of various hosts — ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
