Population & Community Ecology

Unit I
i. Population ecology: population characteristics; growth (geometric, exponential, logistic); dynamics (flux, self thinning) and regulation; population interactions- negative(inter-specific competition, parasitism, predation, herbovory), and positive
(mutualism).ecological niche-definition and concept, niche parameters (niche width, overlap and complementarity), character displacement.
Unit II
i. Community ecology: community concept- and characteristics (analytic and synthetic), guilds; community structure- measurements and indices; species diversity- richness and evenness components; species abundance distribution, diversity patterns (latitudinal gradient- contributory factors and explanatory theories)
Unit III
iii. Community development: temporal changes (cyclic and non-cyclic); stages in hydrach and xerach sucession, mechanism of ecological succession (relay floristics and initial floristic composition; facilitation, tolerance and inhibition models, resource ratio hypothesis); changes in ecosystem properties, concept of climax and its characterization.
Unit IV
ii. Community stability and island biogeography: MacArther and Wilson’s island biogeography equilibrium theory- limitations and modifications; colonization vs. extinction; species area relationship; diversity- disturbance and diversity stability relationship; ecology of plant invasion- process of invasion, characteristics of invasive species, factors promoting community invisibility, impact of invasive species.
iii. Biomes: types (terrestrial and aquatic), distribution and general characteristics.
