manillensis but the deviation in Cytb gene sequence of Pakistani wild rose-ringed parakeets is pointing towards independent evolution of this species as an ecocline in Pakistan.
The eastern San Bernardino Mountains in southern California range from about 3003,506 m and support a wide range of as many as 11 distinct life zones along an ecocline extending from Sonoran Desert on the east side and Mojave Desert on the north side, to an alpine ecosystem near the summit (Schoenherr 1992).
The boundaries of ecoclines are thus both spatial and ecological and when these boundaries are crossed unique interactions can occur, including unexpected predator and prey interactions.
An ecocline of vegetation types for each region was developed on the basis of ecological moisture regimes.
If a region was not accessible or an ecocline contained gaps with respect to moisture regime classes, sequences were either compiled or supplemented with ecosystems from other ecological studies.
Main corresponding vegetation types are tropical evergreen forest, mesophyll montane forest, oak forest, pine forest and oak-pine forest, with extensive ecocline zones between the contiguous types of vegetation (Martinez et al.
To appraise the disease burden at Igbo-Ora, a rural community in the forest-savannah woodland ecocline, south-west Nigeria, an integrated study on malaria immunology and parasitology was initiated in 1991; the entomology and socioeconomic components commenced in 2001.
In the mountains of Mexico's dry tropics gradual transitions between TDF and oak forest are common, and species of both vegetation types may coexist in ecoclines.
In reality, true ecotones only occur in cases in which a given environmental variable changes relatively suddenly, while ecoclines correspond to situations in which the changes in environmental variables are relatively gradual.
Mexico is a unique environment with 34 ecoclines compared to four in the continental United States.
