Pollination Syndromes and Floral Specialization
TLDR
It is shown that pollination syndromes provide great utility in understanding the mechanisms of floral diversification and the importance of organizing pollinators into functional groups according to presumed similarities in the selection pressures they exert.
Predicting the probability of outbreeding depression.
TLDR
An extended form of the breeders' equation was used to predict the probability of OD due to adaptive differentiation between recently isolated population fragments as a function of intensity of selection, genetic diversity, effective population sizes, and generations of isolation.
Genetic variability in natural populations of Arabidopsis thaliana in northern Europe
TLDR
There was a positive association between variability in quantitative traits and microsatellites within populations, and several quantitative traits exhibited QST values significantly less than FST, suggesting that selection may be acting to retard differentiation for these traits.
Implications of different species concepts for conserving biodiversity
TLDR
It is concluded that the diagnostic phylogenetic species concept is unsuitable for use in conservation contexts, especially for classifying allopatric populations.
POPULATION DIFFERENTIATION IN AN ANNUAL LEGUME: LOCAL ADAPTATION
TLDR
It is suggested that metapopulation processes and temporal environmental variation act together to reduce local adaptation, except over long distances, as measured by a home‐site fitness advantage.
FIVE GENERATIONS OF ENFORCED SELFING AND OUTCROSSING IN MIMULUS GUTTATUS: INBREEDING DEPRESSION VARIATION AT THE POPULATION AND FAMILY LEVEL
TLDR
Whether purging of deleterious recessive alleles occurs uniformly between populations and among families is determined, and insights into the mode of gene action governing the expression of inbreeding depression at both the population and family levels across the life cycle are gained.
Floral diversity and community structure in Pedicularis (Orobanchaceae)
TLDR
The results suggest that a dynamic mosaic of pollinator-mediated interactions among Pedicularis in the Hengduan region promotes ecological sorting through recurrent selection against reproductive interference, causing rapid species turnover at local scales, and accelerating the rate of floral divergence among species.
Pollination and seed predation by moths on Silene and allied Caryophyllaceae: evaluating a model system to study the evolution of mutualisms.
TLDR
Reviewing nursery pollination and host-plant interactions in over 30 caryophyllaceous plants, based on published studies and a survey of researchers investigating pollination, seed predation, and moth morphology and behavior found traits and patterns in both that are nonetheless consistent with the evolution of mutualism and merit further attention.
QUANTIFYING GENE FLOW FROM SPATIAL GENETIC STRUCTURE DATA IN A METAPOPULATION OF CHAMAECRISTA FASCICULATA (LEGUMINOSAE)
TLDR
An extensive allozyme survey was conducted within a natural “meta” population of the native North American annual legume to quantify genetic structure at different spatial scales, finding little biparental inbreeding and the effect of a patchy population structure on estimation of gene flow.
POPULATION DIFFERENTIATION IN AN ANNUAL LEGUME: LOCAL ADAPTATION
Abstract Studies of many plants species have demonstrated adaptive genetic differentiation to local environmental conditions. Typically these studies are conducted to evaluate adaptation to
