Document Summary
Clematis remontii in missouri limiting factors of distribution: climate, ecological interaction. Dispersal limitation absence of population from a suitable habitat due to barriers to dispersal. Dispersion spacing of individuals from one another in a geographic range of a population. Clmped distributions can occur due to: to form groups, clustered resources, tendencies to remain close to parents. Ideal free distribution ideal way for animals to distribute themselves among patches. Source sink model: source patch stable, attractive, exporter, sink patch declines to extinction, avoided, importer. Source populations populations that produce enough offspring to sustain themselves and produce excess to disperse into other areas. Continuous time models on instantaneous change in populations. Discrete time length of time. Age structure inflrunces population growth rate. Intrinsic rat of increase exponential. Increasing pop density can depress survival and birth rates and this is referred to as negative density dependence. Recruitment number of offspring per individual to add to the population. Haplotype closely linked genetic markers.
