Ecology of plant speciation
Ecology affects each of the three principal processes leading to speciation: genetic differentiation among populations within species, acquisition of reproductive isolation among populations, and the rise of ecological differentiation among such populations, allowing them to coexist. Until recently, however, the ties between ecology and speciation in plants have received relatively little atten...
متن کاملPlant Virus Ecology
Viruses have generally been studied either as disease-causing infectious agents that have a negative impact on the host (most eukaryote-infecting viruses), or as tools for molecular biology (especially bacteria-infecting viruses, or phage). Virus ecology looks at the more complex issues of virus-host-environment interactions. For plant viruses this includes studies of plant virus biodiversity, ...
متن کاملPlant Virus Biodiversity and Ecology
T he International Committee for the Taxonomy of Viruses recognized a global total of about 2,000 species of viruses as of 2005 [1]. However, data on viruses that infect terrestrial organisms, including plants, are sparse, and recent sequencing of samples from marine environments for viruses suggests that 2,000 is a gross underestimate of the total number of viral species on earth [2]. In addit...
متن کاملPlant polyploidy and the evolutionary ecology of plant/animal interactions
Until recently almost nothing was known about the effects of plant polyploidy on interactions with herbivores and pollinators. Studies of the saxifrage Heuchera grossulariifolia throughout its geographical range in the US northern Rockies have shown that autopolyploidy has probably arisen multiple times within this species since the end of the Pleistocene. Tetraploids from those different origi...
متن کاملEcology and evolution of plant mating.
Plants exhibit complex mating patterns because of their immobility, hermaphroditism and reliance on vectors for pollen transfer. Research on plant mating attempts to determine who mates with whom in plant populations and how and why mating patterns become evolutionarily modified. Most theoretical models of mating-system evolution have focused on the fitness consequences of selling and outcrossi...
