Allozyme diversity in plant species.
Effects of life history traits on genetic diversity in plant species
An analysis of twelve plant families indicated that species within families with predominately outcrossing, woody species had more genetic diversity and less interpopulation differentiation than species withinfamilies with predominate herbaceous species.
Factors influencing levels of genetic diversity in woody plant species
Woody species with large geographic ranges, outcrossing breeding systems, and wind or animal-ingested seed dispersal have more genetic diversity within species and populations but less variation among populations than woodyspecies with other combinations of traits.
ECOLOGICAL DETERMINANTS OF GENETIC STRUCTURE IN PLANT POPULATIONS
This work limits the definition of genetic structure to the nonrandom distribution of alleles or genotypes in space or time and disregard genome organization and meiotic processes that can also affect allele and genotype frequencies.

Relationships Between Life History Characteristics and Electrophoretically Detectable Genetic Variation in Plants
It is found that habitat generalists and animal species with cosmopolitan or tropical distributions were typically more variable than species with specialized habitat preferences or temperate distributions.
Reproductive and Genetic Consequences of Forest Fragmentation: Two Case Studies of Neotropical Canopy Trees
The observed patterns of dispersal in S. mombin and Ficus demonstrate the potential for ecologically and evolutionarily significant pollinator and pollen movement among populations occurring in both disturbed and continuous forest environments, and demonstrates how the conservation of biodiversity in spatially isolated reserves may be dependent on the preservation of forest elements in a surrounding fragmented landscape.
Isozymes and the Analysis of Genetic Structure in Plant Populations
- J. Hamrick
Genetic variation in plant populations is distributed nonrandomly, with marked genetic differences occurring over short distances, like the plants themselves, genes and genotypes tend to be clumped.
Conservation Genetics of Endemic Plant Species
The breeding structure of a tropical keystone plant resource
Paternity analysis techniques are used to reconstruct the genotypes of pollen donor trees and to estimate pollen dispersal distances and breeding population size parameters for Panamanian populations of seven species of monoecious strangler figs, a particularly widespread and influential group of keystone producers.
