Philippine Scops Owl
The Philippine scops owl (''Otus megalotis'') is a common owl, endemic to the Philippines, belonging to the family of the typical owls Strigidae. Other common names include "Otus Whitehead", "Whitehead scops owl" and "Luzon lowland scops owl". Everett's scops owl (''Otus everetti)'' and Negros scops owls (''Otus nigrorum)'' were formerly considered conspecific but are now classified as separate species. Distinguishing features of these birds include their large upright ears from which they get their specific name ''megalotis'', Ancient Greek for "large ears". Philippine scops owls are relatively small, sedentary birds that are naturally found in the forest understory. There are three subspecies which show variations in morphology and are distributed among different islands of the Philippine Archipelago. They are a monogamous species that offer parental care and construct their nest in tree cavities. These owls are ferocious nocturnal carnivores that feed on insects and small ma ...

True Owl
The true owls or typical owls (family Strigidae) are one of the two generally accepted families of owls, the other being the barn owls (Tytonidae). This large family comprises 230 living or recently extinct species in 24 genera. The typical owls have a cosmopolitan distribution and are found on every continent except Antarctica. Morphology While typical owls (hereafter referred to simply as owls) vary greatly in size, with the smallest species, the elf owl, being a hundredth the size of the largest, the Eurasian eagle-owl and Blakiston's fish owl, owls generally share an extremely similar body plan.Marks, J. S.; Cannings, R.J. and Mikkola, H. (1999). "Family Strigidae (Typical Owls)". ''In'' del Hoyo, J.; Elliot, A. & Sargatal, J. (eds.) (1999). '' Handbook of the Birds of the World.

Mantanani Scops Owl
The Mantanani scops owl (''Otus mantananensis''), is a small owl in the scops-owl genus ''Otus'' found on small islands between Borneo and the Philippines. It is listed by the IUCN as "near threatened" because its range is limited with its population being fragmented on several different islands, and its forest habitat is being degraded by ongoing logging and clearance. Description and Taxonomy This owl is about 18 cm long, with a wing length of about 15.5 cm. It has a buff facial disk with a narrow, dark border. It has dark brown upperparts with pale markings on the scapulars, and pale underparts with dark streaks and barring. It has yellow irides, grey feet and bill, and feathered tarsi. This owl hunts at the forest edge or in clearings, feeding mainly on insects. It is thought to breed from March to May with its eggs being laid in a tree hollow. The voice has been described as a simple ''waa'' and a goose-like honk, with a descending series of short ''wa''s during ter ...

Palawan Scops Owl
The Palawan scops owl (''Otus fuliginosus'') is an owl endemic to the Philippines only being found on the island of Palawan. It is found on tropical moist lowland forest. It is threatened by habitat loss. Description EBird describes the bird as "A fairly small owl of lowland forest. Dark brown above with a white bar behind the shoulder, and paler and warmer brown below with black marks. Note the wide, shallow V-shape stretching from between the eyes out to the ends of the prominent ear tufts, and the dark facial shield incompletely bordered with white below. Eyes are deep orange. Similar to Mantanani Scops-Owl, which only occurs on small offshore islands off Palawan, but differs in eye color. Voice is a low rasping croak, 'gruk grrrrrrrrr'." Habitat and conservation status Its habitat is in tropical moist lowland primary and secondary forest and even mixed cultivated areas – as long as there are still trees. IUCN has assessed this bird as near threatened with the popu ... [...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 representation of t ...

Biome
A biome () is a biogeographical unit consisting of a biological community that has formed in response to the physical environment in which they are found and a shared regional climate. Biomes may span more than one continent. Biome is a broader term than habitat and can comprise a variety of habitats. While a biome can cover large areas, a microbiome is a mix of organisms that coexist in a defined space on a much smaller scale. For example, the human microbiome is the collection of bacteria, viruses, and other microorganisms that are present on or in a human body. A biota is the total collection of organisms of a geographic region or a time period, from local geographic scales and instantaneous temporal scales all the way up to whole-planet and whole-timescale spatiotemporal scales. The biotas of the Earth make up the biosphere. Etymology The term was suggested in 1916 by Clements, originally as a synonym for '' biotic community'' of Möbius (1877). Later, it gained its c ...

Phylogeography
Phylogeography is the study of the historical processes that may be responsible for the past to present geographic distributions of genealogical lineages. This is accomplished by considering the geographic distribution of individuals in light of genetics, particularly population genetics. This term was introduced to describe geographically structured genetic signals within and among species. An explicit focus on a species' biogeography/biogeographical past sets phylogeography apart from classical population genetics and phylogenetics. Past events that can be inferred include population expansion, population bottlenecks, vicariance, dispersal, and migration. Recently developed approaches integrating coalescent theory or the genealogical history of alleles and distributional information can more accurately address the relative roles of these different historical forces in shaping current patterns. Development The term phylogeography was first used by John Avise in his 1987 work '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Speciation
Speciation is the evolutionary process by which populations evolve to become distinct species. The biologist Orator F. Cook coined the term in 1906 for cladogenesis, the splitting of lineages, as opposed to anagenesis, phyletic evolution within lineages. Charles Darwin was the first to describe the role of natural selection in speciation in his 1859 book ''On the Origin of Species''. He also identified sexual selection as a likely mechanism, but found it problematic. There are four geographic modes of speciation in nature, based on the extent to which speciating populations are isolated from one another: allopatric speciation, allopatric, peripatric speciation, peripatric, parapatric speciation, parapatric, and sympatric speciation, sympatric. Speciation may also be induced artificially, through animal husbandry, agriculture, or laboratory experiments of speciation, laboratory experiments. Whether genetic drift is a minor or major contributor to speciation is the subject of much ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flammulated Owl
The flammulated owl (''Psiloscops flammeolus'') is a small migratory North American owl in the family Strigidae. It is the only species placed in the genus ''Psiloscops''. Taxonomy The flammulated owl was formally described in 1852 by the German naturalist Johann Jakob Kaup under the binomial name ''Scops flammeola ''. He specified the type location as Mexico. This species was formerly placed with the scops owls in the genus ''Otus'' but is now placed in its own genus ''Psiloscops'' that was introduced in 1899 by Elliott Coues. The name ''Psiloscops'' combines the Ancient Greek ''psilos'' meaning "naked" or "smooth" with the genus name ''Scops'', a synonym of ''Otus''. The specific epithet ''flammeolus'' is Latin meaning "flame-coloured", "with flame-like markings" or "flammulated". The species is monotypic: no subspecies are recognised. A molecular phylogenetic study of the owls published in 2019 found that the flammulated owl is a sister species to the Puerto Rican owl (''G ...
