The study area is geographically formed by 33 administrative villages which will be referred to as communities and serve as a unit of analysis in this study.
Tucked away in the far north-east of the country, Manipur is geographically isolated form the rest of India, and the state has missed out on the economic boom that much of the country has recently enjoyed.
Ring species, exemplified by salamanders of the Ensatina eschscholtzii complex, represent a special window into the speciation process because they allow the history of species formation to be traced back in time through the geographically differentiated forms connecting the two terminal forms of the ring.
Ferlus (2010) lists other, more geographically restricted forms: proto-Katuic *s-rɔ: 'paddy, raw rice', also found in Mon, Khmer and Sora (Munda) and a form *s-ŋɔʔ 'paddy, raw rice' found in Palaung-Wa, Khmu and Mon.
Biology in itself has become 'big science' (Vermeulen et al. 2013), with institutional collaboration and geographically distributed forms of endeavours.
Two geographically distinct forms are recognised: ;Banksia ericifolia subsp. ericifolia: The nominate race is found in the Sydney basin, south to the Illawarra and north to Collaroy, as well as the Blue Mountains.
Although Goldman recommended to him that gatunensis and azuerensis both be treated as subspecies of couesi, Bole described azuerensis as a species because it did not seem intermediate between the geographically closest forms, gatunensis and couesi, and was separated by a large gap from the nearest known populations of O. couesi in northwestern Costa Rica and southeastern Nicaragua.
Here, we present a detailed genetic analysis of a hybrid zone on Palomar Mountain between the geographically terminal forms of the Ensatina complex.
Of particular interest is the nature and extent of reproductive isolation between the geographically terminal forms, in this case E. e. eschscholtzii and E. e. klauberi.
In geographically distributed forms of global science projects such as the Encyclopedia of Life, which documents all living species known to science, non-experts also contribute to data collection in the form of video, sound, images, graphics and text.
