Todus Mexicanus
The Puerto Rican tody (''Todus mexicanus'') is a bird endemic to Puerto Rico. It is locally known in Spanish as "San Pedrito" ("little Saint Peter") and "medio peso" ("half-dollar bird"). Taxonomy Todies are the closest relative to the motmots of Central America. It is thought that the Jamaican tody (''Todus todus'') gave rise to the Puerto Rican tody after hurricane dispersals, but the relationship between both species has not yet been confirmed. Studies show the ''Todus'' genus probably developed before the Pleistocene. Mitochondrial gene studies point to the motmots as their closest relative, although egg white protein electrophoresis studies suggest a relationship to kingfishers. The Puerto Rican tody's specific epithet, ''mexicanus'' (Latin for "from Mexico"), is a misnomer; it is thought that the ornithologist who first described it, René Lesson, erroneously wrote the type specimen's retrieval location as Mexico. The Puerto Rican tody makes up one of the five endemic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fauna Of Puerto Rico
The fauna of Puerto Rico is similar to other island archipelago faunas, with high endemism, and low, skewed taxonomic diversity. Bats are the only extant native terrestrial mammals in Puerto Rico. All other terrestrial mammals in the area were introduced by humans, and include species such as cats, goats, sheep, the small Indian mongoose, and escaped monkeys. Marine mammals include dolphins, manatees, and whales. Of the 349 bird species, about 120 breed in the archipelago, and 47.5% are accidental or rare. The most recognizable and famous animal of Puerto Rico is probably the common coquí, a small endemic frog, and one of the 86 species that constitute Puerto Rico's herpetofauna. Some native freshwater fish inhabit Puerto Rico, but some species, introduced by humans, have established populations in reservoirs and rivers. The low richness-high diversity pattern is also apparent among invertebrates, which constitutes most of the archipelago's fauna. The arrival of the first peo ...

Indian Gray Mongoose
The Indian grey mongoose (''Urva edwardsii'') is a mongoose species native to the Indian subcontinent and West Asia. It is listed as Least Concern on the IUCN Red List. The grey mongoose inhabits open forests, scrublands and cultivated fields, often close to human habitation. It lives in burrows, hedgerows and thickets, among groves of trees, and takes shelter under rocks or bushes and even in drains. It is bold and inquisitive but wary, seldom venturing far from cover. It is an excellent climber and usually lives singly or in pairs. Its prey includes rodents, snakes, birds’ eggs and hatchlings, lizards and a variety of invertebrates. Along the Chambal River it occasionally feeds on gharial eggs. It breeds throughout the year. Characteristics The Indian grey mongoose has tawny grey or iron grey fur, which is more grizzled and stiffer and coarser than that of other mongooses. The ruddiness of the coat varies in different subspecies, but it is described as appearing more grey ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Least-concern Species
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the "Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evaluate ...

Coraciiformes
The Coraciiformes are a group of usually colourful birds including the kingfishers, the bee-eaters, the rollers, the motmots, and the todies. They generally have syndactyly, with three forward-pointing toes (and toes 3 & 4 fused at their base), though in many kingfishers one of these is missing. The members of this order are linked by their “slamming” behaviour, thrashing their prey onto surfaces to disarm or incapacitate them. This is largely an Old World order, with the representation in the New World limited to the dozen or so species of todies and motmots, and a mere handful of the more than a hundred species of kingfishers. The name Coraciiformes means " raven-like". Specifically, it comes from the Latin language "corax", meaning "raven" and Latin "forma", meaning "form", which is the standard ending for bird orders. Systematics This order has been seen to be something of a mixed assortment, and the Coraciiformes may be considered as including only the rollers. ...

Heterothermy
Heterothermy or heterothermia (from Greek ἕτερος ''heteros'' "other" and θέρμη ''thermē'' "heat") is a physiological term for animals that vary between self-regulating their body temperature, and allowing the surrounding environment to affect it. In other words, they exhibit characteristics of both poikilothermy and homeothermy. Definition Heterothermic animals are those that can switch between poikilothermic and homeothermic strategies. These changes in strategies typically occur on a daily basis or on an annual basis. More often than not, it is used as a way to dissociate the fluctuating metabolic rates seen in some small mammals and birds (e.g. bats and hummingbirds), from those of traditional cold blooded animals. In many bat species, body temperature and metabolic rate are elevated only during activity. When at rest, these animals reduce their metabolisms drastically, which results in their body temperature dropping to that of the surrounding environment. This ma ...

Guánica State Forest
The Guánica State Forest ( es, Bosque Estatal de Guánica), popularly known as the Guánica Dry Forest (Spanish: ''Bosque seco de Guánica'') is a subtropical dry forest located in southwest Puerto Rico. The area was designated as a forest reserve in 1919 and a United Nations Biosphere Reserve in 1981. It is considered the best preserved subtropical dry forest and the best example of dry forest in the Caribbean. With approximately 10,000 acres, it is the largest of the 20 state forests of Puerto Rico, and it extends over 5 municipalities: Guánica, Guayanilla, Peñuelas, Ponce, and Yauco (although the forest units located in the municipalities of Peñuelas and Ponce only consist of keys and small islands). History The dry forest area of southwestern Puerto Rico protected under the jurisdiction of the Guánica Dry Forest was first established in 1919 as a forest reserve. The United Nations recognized the ecological value of the forest in 1981 when it was designated a Biosph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geography Of Puerto Rico
The geography of Puerto Rico consists of an archipelago located between the Caribbean Sea and the North Atlantic Ocean, east of the Dominican Republic or Hispaniola, west of the Virgin Islands and north of Venezuela. The main island of Puerto Rico is the smallest and most eastern of the Greater Antilles. With an area of , it is the third largest island in the United States and the 82nd largest island in the world. Various smaller islands and cays, including Vieques, Culebra, Mona, Desecheo, and Caja de Muertos comprise the remainder of the archipelago with only Culebra and Vieques being inhabited year-round. Mona is uninhabited through large parts of the year except for employees of the Puerto Rico Department of Natural Resources. The mainland measures some by , larger than the state of Rhode Island but smaller than Connecticut. It is mostly mountainous with large coastal areas in the north and south regions of the island.
