William Brewster (ornithologist)
William Brewster (July 5, 1851 – July 11, 1919) was an American ornithologist, Natural history, naturalist, and Conservation movement, conservationist. He worked as a curator at the Museum of Comparative Zoology at Harvard University, co-founded the American Ornithologists' Union and the Nuttall Ornithological Club, and served as the first president of Massachusetts Audubon Society, Mass Audubon. Early life and education Childhood William Brewster was born on July 5, 1851, in South Reading (now Wakefield, Massachusetts, Wakefield), Massachusetts, the youngest of four children born to John Brewster, a successful Boston banker, and Rebecca Parker (Noyes). The couple settled in Cambridge, Massachusetts, Cambridge, Massachusetts in 1845. Brewster's sister and older brothers died in early childhood, inspiring Henry Wadsworth Longfellow, Longfellow, a close neighbor, to write the poem ''The Open Window''. Brewster attended Cambridge public schools, Washington Grammar School and Camb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subspecies
In Taxonomy (biology), biological classification, subspecies (: subspecies) is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (Morphology (biology), morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated as subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific name, infraspecific ranks, such as variety (botany), variety, may be named. In bacteriology and virology, under standard International Code of Nomenclature of Prokaryotes, bacterial nomenclature and virus clas ...

Birds Described In 1901
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 orders. More than half are passerine or "perching" birds. Birds have wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have fur ...

Endemic Birds Of Jamaica
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are Indigenous (ecology), indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a la ...

Hummingbird Species Of Central America
Hummingbirds are birds native to the Americas and comprise the biological family Trochilidae. With approximately 366 species and 113 genera, they occur from Alaska to Tierra del Fuego, but most species are found in Central and South America. As of 2024, 21 hummingbird species are listed as endangered or critically endangered, with numerous species declining in population. Hummingbirds have varied specialized characteristics to enable rapid, maneuverable flight: exceptional metabolic capacity, adaptations to high altitude, sensitive visual and communication abilities, and long-distance migration in some species. Among all birds, male hummingbirds have the widest diversity of plumage color, particularly in blues, greens, and purples. Hummingbirds are the smallest mature birds, measuring in length. The smallest is the bee hummingbird, which weighs less than , and the largest is the giant hummingbird, weighing . Noted for long beaks, hummingbirds are specialized for feeding ...

Trochilus
The streamertails are hummingbirds in the genus ''Trochilus'' that are endemic to Jamaica. It is the type genus of the family Trochilidae. Today, most authorities consider the two taxa in this genus as separate species, but some (e.g. AOU) continue to treat them as conspecific, in which case ''T. scitulus'' is a subspecies of ''T. polytmus''. A wide range of common names applies to this combined species, including green-and-black streamertail, Jamaican streamertail, or simply streamertail. The name "streamertail" is a reference to the greatly elongated rectrices of the males. Taxonomy and species list The genus ''Trochilus'' was introduced in 1758 by Swedish naturalist Carl Linnaeus in the 10th edition of his ''Systema Naturae''. The genus name is from the Ancient Greek τροχιλος/''trokhilos'', a small unidentified bird mentioned by Aristotle. Later authors assumed the word referred to a wren.

IUCN
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and Data analysis, 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 buildin ...

Yellow-bellied Sapsucker
The yellow-bellied sapsucker (''Sphyrapicus varius'') is a medium-sized woodpecker that breeds in Canada and the northeastern United States. Taxonomy The yellow-bellied sapsucker was described and illustrated using a hand-coloured plate by the English naturalist Mark Catesby in his ''The Natural History of Carolina, Florida and the Bahama Islands'' which was published between 1729 and 1732. When in 1766 the Swedish naturalist Carl Linnaeus updated his ''Systema Naturae'' for the twelfth edition, he included the yellow-bellied sapsucker, coined the binomial name ''Picus varius'' and cited Catesby's book. The specific epithet ''varius'' is the Latin word meaning "various", "diverse" or "variegated". Linnaeus specified the type locality as ''America septentrionalis'' (North America) but the locality is now restricted to South Carolina. The yellow-bellied sapsucker is now placed in the genus '' Sphyrapicus'' that was erected in 1858 by the American naturalist Spencer Baird with th ...

Bananaquit
The bananaquit (''Coereba flaveola'') is a species of passerine bird in the tanager family Thraupidae. Before the development of molecular genetics in the 21st century, its relationship to other species was uncertain and it was either placed with the buntings and New World sparrows in the family Emberizidae, with New World warblers in the family Parulidae or its own monotypic family Coerebidae. This small, active nectarivore is found in warmer parts of the Americas and is generally common. Its name is derived from its yellow color and the English word '' quit'', which refers to small passerines of tropical America; cf. grassquit, orangequit. Taxonomy The bananaquit was formally described by Carl Linnaeus in his landmark 1758 10th edition of ''Systema Naturae'' as ''Certhia flaveola''. Linnaeus based his description on the "black and yellow bird" described by John Ray and Hans Sloane, and the "Black and Yellow Creeper" described and illustrated by George Edwards in 1751. The ...

Besleria
''Besleria'' is a genus of large herbs and soft-stemmed subshrubs or shrubs in the flowering plant family Gesneriaceae. It includes 176 species native to tropical southern Mexico, Central America, South America, and the West Indies. The closely related genus ''Gasteranthus'' was previously included in ''Besleria''. The two genera have been separated on the basis of stomatal (aggregated in ''Gasteranthus'', scattered in ''Besleria'') and fruit (fleshy capsule in ''Gasteranthus'', berry A berry is a small, pulpy, and often edible fruit.

Secondary Forest
A secondary forest (or second-growth forest) is a forest or woodland area which has regenerated through largely natural processes after human-caused Disturbance (ecology), disturbances, such as Logging, timber harvest or agriculture clearing, or equivalently disruptive natural phenomena. It is distinguished from an old-growth forest (primary or primeval forest), which has not recently undergone such disruption, and complex early Seral community, seral forest, as well as third-growth forests that result from harvest in second growth forests. Secondary forest regrowing after timber harvest differs from forest Ecological succession, regrowing after natural Disturbance (ecology), disturbances such as Wildfire, fire, insect infestation, or windthrow because the dead trees remain to provide nutrients, structure, and water retention after natural disturbances. Secondary forests are notably different from primary forests in their composition and biodiversity; however, they may still be hel ...

Montane Forest
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures lapse rate, fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands and shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the alpine climate, climate becomes co ...
