Dusky Pigeon
The dusky pigeon (''Patagioenas goodsoni'') is a species of bird in the family Columbidae. It is found in Colombia and Ecuador. Taxonomy and systematics The dusky pigeon is most closely related to the ruddy pigeon (''P. subvinacea''), short-billed pigeon (''P. nigrirostris''), and plumbeous pigeon (''P. plumbia''), and they have sometimes been placed in subgenus ''Oenoenas''.Remsen, J.

Ernst Hartert
Ernst Johann Otto Hartert (29 October 1859 – 11 November 1933) was a widely published German ornithologist. Life and career Hartert was born in Hamburg, Germany on 29 October 1859. In July 1891, he married the illustrator Claudia Bernadine Elisabeth Hartert in Frankfurt am Main, Germany, with whom he had a son named Joachim Karl (Charles) Hartert, (1893–1916), who was killed as an English soldier on the Somme. Together with his wife, he was the first to describe the blue-tailed Buffon hummingbird subspecies (''Chalybura buffonii intermedia'' Hartert, E & Hartert, C, 1894). The article ''On a collection of Humming Birds from Ecuador and Mexico'' appears to be their only joint publication. Hartert was employed by Walter Rothschild, 2nd Baron Rothschild as ornithological curator of Rothshild's private Natural History Museum at Tring, in England from 1892 to 1929. Hartert published the quarterly museum periodical ''Novitates Zoologicae'' (1894–39) with Rothschild, and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tumbes–Chocó–Magdalena
Tumbes-Chocó-Magdalena is a biodiversity hotspot, which includes the tropical moist forests and tropical dry forests of the Pacific coast of South America and the Galapagos Islands. The region extends from easternmost Panama to the lower Magdalena Valley of Colombia, and along the Pacific coast of Colombia and Ecuador to the northwestern corner of Peru. Formerly called the Chocó-Darién-Western Ecuador Hotspot, it has been expanded to include several new areas, notably the Magdalena Valley in northern Colombia. It is bounded on the east by the Andes Mountains. The Tumbes-Choco-Magdalena Hotspot is 1,500 km long and encircles 274,597 km². Tumbes-Choco-Magdalena is near the Pacific Ocean. The factors that threaten Tumbes-Choco-Magdalena are farming encroachment, deforestation, illegal crops, and population growth. Whereas the Panamanian and Colombian portion of the hotspot are relatively intact, approximately 98% of native forest in coastal Ecuador has been cleared, re ...

Birds Of The Tumbes-Chocó-Magdalena
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 ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have 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 further evolved for swimming. Bird ...

Patagioenas
''Patagioenas'' is a genus of New World pigeons whose distinctness from the genus ''Columba'' was long disputed but ultimately confirmed. It is basal to the ''Columba''-''Streptopelia'' radiation. Their ancestors diverged from that lineage probably over 8 million years ago. While the biogeographic pattern of this group suggests that the ancestors of the typical pigeons and turtle-doves settled the Old World from the Americas, ''Patagioenas'' may just as well be the offspring of Old World pigeons which only radiated into different genera later, given that the cuckoo-doves (''Macropygia'') of Southeast Asia also seem to be closely related.Johnson ''et al.'' (2001), Cheke (2005) Taxonomy The genus ''Patagioenas'' was introduced by the German naturalist Ludwig Reichenbach in 1853 with the white-crowned pigeon (''Patagioenas leucocephala'') as the type species. The genus name combines the Ancient Greek ''patageō'' meaning "to clatter" and ''oinas'' meaning "pigeon". There are 17 s ...

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] |
Phenology
Phenology is the study of periodic events in biological life cycles and how these are influenced by seasonality, seasonal and interannual variations in climate, as well as environmental factor, habitat factors (such as elevation). Examples include the date of emergence of leaves and flowers, the first flight of butterflies, the first appearance of bird migration, migratory birds, the date of leaf colouring and fall in deciduous trees, the dates of egg-laying of birds and amphibia, or the timing of the developmental cycles of temperate-zone honey bee colonies. In the scientific literature on ecology, the term is used more generally to indicate the time frame for any seasonal biological phenomena, including the dates of last appearance (e.g., the seasonal phenology of a species may be from April through September). Because many such phenomena are very sensitive to small variations in climate, especially to temperature, phenological records can be a useful proxy (climate), proxy for ...

Rainforest
Rainforests are characterized by a closed and continuous tree canopy, moisture-dependent vegetation, the presence of epiphytes and lianas and the absence of wildfire. Rainforest can be classified as tropical rainforest or temperate rainforest, but other types have been described. Estimates vary from 40% to 75% of all biotic species being indigenous to the rainforests. There may be many millions of species of plants, insects and microorganisms still undiscovered in tropical rainforests. Tropical rainforests have been called the "jewels of the Earth" and the " world's largest pharmacy", because over one quarter of natural medicines have been discovered there. Rainforests as well as endemic rainforest species are rapidly disappearing due to deforestation, the resulting habitat loss and pollution of the atmosphere. Definition Rainforest are characterized by a closed and continuous tree canopy, high humidity, the presence of moisture-dependent vegetation, a moist layer of lea ...

Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda. ...
