Kin competition and the evolution of cooperation.
Kin and multilevel selection theories predict that genetic structure is required for the evolution of cooperation. However, local competition among relatives can limit cooperative benefits, antagonizing the evolution of cooperation. We show that several ecological factors determine the extent to which kin competition constrains cooperative benefits. In addition, we argue that cooperative acts t...
متن کاملDemonstration of pollinator-mediated competition between two native Impatiens species, Impatiens noli-tangere and I. textori (Balsaminaceae)
Plant-plant interspecific competition via pollinators occurs when the flowering seasons of two or more plant species overlap and the pollinator fauna is shared. Negative sexual interactions between species (reproductive interference) through improper heterospecific pollen transfer have recently been reported between native and invasive species demonstrating pollination-driven competition. We fo...
متن کاملCompetition, cooperation among kin, and virulence in multiple infections.
Critical determinants of the optimum level of virulence in pathogens include the presence of competitors (i.e., multiple infections), their relatedness, and the effect of competitors on pathogen growth and disease development. Empirical data regarding the existence of competitive interactions and their impact on virulence remain very limited compared to theoretical studies. Here, we followed an...
متن کاملTesting for stress-dependent inbreeding depression in Impatiens capensis (Balsaminaceae).
The relevance of inbreeding depression to the persistence of plant populations can depend upon whether stress magnifies inbreeding depression for fitness-related traits. To examine whether drought stress exacerbates inbreeding depression in gas exchange traits and biomass, we grew selfed and outcrossed progeny of inbred lines from two populations of Impatiens capensis in a greenhouse experiment...
متن کاملImpatiens bokorensis (Balsaminaceae), a new species from Cambodia
Impatiens bokorensis, a new species of family Balsaminaceae from Phnum Bokor National Park in southwestern Cambodia, is described and illustrated. The species is similar to Impatiens patula, but is readily distinguished by the orbicular-obovate dorsal petal, shorter pedicels and larger seeds.
