Little Sumba Boobook
The least boobook (''Ninox sumbaensis''), also known as the little Sumba hawk-owl or little Sumba boobook, is a species of owl in the family Strigidae. It is endemic to the Indonesian island of Sumba. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss. History In the 1980s ornithologists knew that there was an unknown species of owl on the island of Sumba. A phylogenetic analysis undertaken on a sample feather showed that the owl was an unknown species in the genus ''Ninox''. The bird had a characteristic low whistling call "''who''", repeated at four second intervals, which distinguished it from other known species of owl. When this call was recorded and played back on Sumba, there was a response from resident birds. In late 2001 a specimen of the bird was obtained, enabling a detailed description to be made for the first time; it was named ''Ninox sumbaensis'', the least boobook. Description The least boobook is about long a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strigidae
The true owls or typical owls (family (biology), family Strigidae) are one of the two generally accepted families of owls, the other being the barn owls and bay owls (Tytonidae). This large family comprises 230 living or recently extinct species in 24 genus, genera. The Strigidae 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.

Endemic
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 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 larger area or bec ...

Habitat
In ecology, habitat refers to the array of resources, biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species' habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as Biophysical environment, environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and Luminous intensity, light intensity. Biotic index, Biotic factors include the availability of food and the presence or absence of Predation, predators. Every species has particular habitat requirements, habitat generalist species are able to thrive in a wide array of environmental conditions while habitat specialist species require a very limited set of factors to survive. The habitat of a species is not necessarily found in a ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forest
A forest is an ecosystem characterized by a dense ecological community, community of trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a Canopy (biology), canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, ''Global Forest Resources Assessment (FRA), Global Forest Resources Assessment 2020'' found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the largest Terrestrial ecosystem, terrestrial ecosystems of Earth by area, and are found around the globe. 45 percent of forest land is in the Tropical forest, trop ...

Habitat Loss
Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease in biodiversity and Abundance (ecology), species numbers. Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide. Humans contribute to habitat destruction through the Exploitation of natural resources, use of natural resources, agriculture, industrial production and urbanization (urban sprawl). Other activities include mining, logging and trawling. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introduced species, introduction of invasive species, ecosystem nutrient depletion, water pollution, water and noise pollution are some examples. Loss of habitat can be preceded by an initial habitat fragmentation. Fragmentation and lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phylogenetics
In biology, phylogenetics () is the study of the evolutionary history of life using observable characteristics of organisms (or genes), which is known as phylogenetic inference. It infers the relationship among organisms based on empirical data and observed heritable traits of DNA sequences, protein amino acid sequences, and morphology. The results are a phylogenetic tree—a diagram depicting the hypothetical relationships among the organisms, reflecting their inferred evolutionary history. The tips of a phylogenetic tree represent the observed entities, which can be living taxa or fossils. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the taxa represented on the tree. An unrooted tree diagram (a network) makes no assumption about directionality of character state transformation, and does not show the origin or "root" of the taxa in question. In addition to their use for inferring phylogenetic pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ninox
''Ninox'' is a genus of true owls comprising 36 species found in Asia and Australasia. Many species are known as hawk-owls or boobooks, but the northern hawk-owl (''Surnia ulula'') is not a member of this genus. Taxonomy The genus was introduced by English naturalist Brian Houghton Hodgson in 1837 with the type species as ''Ninox nipalensis'', a junior synonym of ''Strix lugubris'' Tickell 1833. ''Strix lugubris'' is now considered a subspecies of the brown boobook (''Ninox scutula lugubris''). Species The genus contains 37 species: *† Laughing owl, ''Ninox albifacies'' (extinct) * Rufous owl, ''Ninox rufa'' * Powerful owl, ''Ninox strenua'' * Barking owl, ''Ninox connivens'' * Sumba boobook, ''Ninox rudolfi'' * Australian boobook, ''Ninox boobook'' * Rote boobook ''Ninox rotiensis'' * Timor boobook ''Ninox fusca'' * Alor boobook, ''Ninox plesseni'' * Tasmanian boobook, ''Ninox leucopsis'' * Morepork, ''Ninox novaeseelandiae'' * Northern boobook, ''Ninox japonica ...

Endangered
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, invasive species, and climate change. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct.
