Chinese Leaf Warbler
The Chinese leaf warbler (''Phylloscopus yunnanensis'') is a species of Old World warbler in the family Phylloscopidae. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical high-altitude shrubland. It is found only in China. Etymology The Chinese leaf warbler’s scientific binomial name, ''Phylloscopus yunnanensis'', originates from the Irish ornithological naturalist authority John David Digues La Touche in 1922. A more recent Latin "junior synonym" alternate scientific name is ''P. sichuanensis'' from 1992. ''Yunnanensis'' and ''sichuanensis'' derive from the Yunnan and Sichuan provinces in China. Description The Chinese leaf warbler is a brightly colored, small leaf-warbler, with a total length of around 10 cm and a wing length of 5–6 cm. Its body is slightly elongated and compact. The warbler has a slightly forked or notched tail that is almost square in shape. Its bill is pointed and short (around 1 cm long) and dark b ...

Secondary Forest
A secondary forest (or second-growth forest) is a forest or woodland area which has re-grown after a timber harvest or clearing for agriculture, until a long enough period has passed so that the effects of the disturbance are no longer evident. It is distinguished from an old-growth forest (primary or primeval forest), which has not recently undergone such disruption, and complex early 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 regrowing after natural disturbances such as fire, insect infestation, or windthrow because the dead trees remain to provide nutrients, structure, and water retention after natural disturbances. However, often after natural disturbance the timber is harvested and removed from the system, in which case the system more closely resembles secondary forest rather than seral forest. Description Depending on the forest, the development of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

British Ornithologists' Club
The British Ornithologists' Club (BOC) aims to promote discussion between members and others interested in ornithology, and to facilitate the dissemination of scientific information concerned with ornithology. The BOC has a special interest in avian systematics, taxonomy and distribution. The BOC was founded at a meeting of 15 members of the British Ornithologists' Union held in Covent Garden, London on 5 October 1892. This was at a time when individuals and expeditions were exploring remote parts of the world, discovering many new species of birds in the process and the BOC was formed to enable members to meet regularly to present papers, exhibit specimens and engage in discussion on wider ornithological matters. The BOC has continued to meet regularly in London (with occasional meetings elsewhere) and, as at June 2012, has held 970 meetings. Meetings now take the form of a talk followed by discussion, with refreshments available afterwards. Meetings are free and are open to me ...

Bulletin Of The British Ornithologists' Club
The ''Bulletin of the British Ornithologists' Club'' is an ornithological journal published by the British Ornithologists' Club (BOC). It is cited as ''Bull. B. O. C.'' Many descriptions of birds new to science have been published in the bulletin. The journal was first published in 1892. It is published in four quarterly issues. from March 2017 (Vol. 137 No. 1), it became an online-only, open access, journal, giving as the reasons for the change: Since 2004, the journal's honorary editor has been Guy Kirwan.

Science Society Of China
The Science Society of China (, 1915-1960) was a major science organization in the modern history of China. It was initiated by Chinese students at Cornell University in 1914, including P.C. King, H. C. Zen, Zhou Ren, Hsingfo Yang and later renamed Science Society of China. In 1915 it began publication in China of a major journal, ''Kexue'' (''Science''), which was patterned on the journal of the American Association for the Advancement of Science. In 1918 Science Society of China founded headquarters in Nanjing. In 1922 the Society established a major biological research laboratory in Nanjing. The Society devoted itself to the popularization of science, the improvement of science education, the standardization in Chinese translation of scientific vocabularies, and participation in international scientific meetings. It was the leading scientific organization in China prior to the establishment of government-sponsored Academia Sinica (1928) and Chinese Academy of Sciences (1949). ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Bird Vocalization
Bird vocalization includes both bird calls and bird songs. In non-technical use, bird songs are the bird sounds that are melodious to the human ear. In ornithology and birding, songs (relatively complex vocalizations) are distinguished by function from calls (relatively simple vocalizations). Definition The distinction between songs and calls is based upon complexity, length, and context. Songs are longer and more complex and are associated with territory and courtship and mating, while calls tend to serve such functions as alarms or keeping members of a flock in contact. Other authorities such as Howell and Webb (1995) make the distinction based on function, so that short vocalizations, such as those of pigeons, and even non-vocal sounds, such as the drumming of woodpeckers and the "winnowing" of snipes' wings in display flight, are considered songs. Still others require song to have syllabic diversity and temporal regularity akin to the repetitive and transformative patte ...

Seasonal Breeder
Seasonal breeders are animal species that successfully mate only during certain times of the year. These times of year allow for the optimization of survival of young due to factors such as ambient temperature, food and water availability, and changes in the predation behaviors of other species. Related sexual interest and behaviors are expressed and accepted only during this period. Female seasonal breeders will have one or more estrus cycles only when she is "in season" or fertile and receptive to mating. At other times of the year, they will be anestrus, or have a dearth of their sexual cycle. Unlike reproductive cyclicity, seasonality is described in both males and females. Male seasonal breeders may exhibit changes in testosterone levels, testes weight, and fertility depending on the time of year. Seasonal breeders are distinct from opportunistic breeders, that mate whenever the conditions of their environment become favorable, and continuous breeders that mate year-round. T ...

Spruce
A spruce is a tree of the genus ''Picea'' (), a genus of about 35 species of coniferous evergreen trees in the family Pinaceae, found in the northern temperate and boreal (taiga) regions of the Earth. ''Picea'' is the sole genus in the subfamily Piceoideae. Spruces are large trees, from about 20 to 60 m (about 60–200 ft) tall when mature, and have whorled branches and conical form. They can be distinguished from other members of the pine family by their needles (leaves), which are four-sided and attached singly to small persistent peg-like structures (pulvini or sterigmata) on the branches, and by their cones (without any protruding bracts), which hang downwards after they are pollinated. The needles are shed when 4–10 years old, leaving the branches rough with the retained pegs. In other similar genera, the branches are fairly smooth. Spruce are used as food plants by the larvae of some Lepidoptera (moth and butterfly) species, such as the eastern spruce budwo ...
