American Journal of Botany, Vol. 80, No. 1 (Jan., 1993), pp. 45-52 (8 pages) The population genetics and mating system of the understory tropical rain forest tree Psychotria faxlucens were studied at ...
AbstractPersistence and adaptation in novel environments are limited by small population size, strong selection, and maladaptive gene flow. Mating system plasticity is common in angiosperms and may ...
We have developed a new model for mating system analysis, which attempts to distinguish among alternative modes of self-oriented mating within populations. This model jointly estimates the rates of ...
Mating patterns in flowering plants are products of complex interactions between reproductive traits and the ecology of populations (Lloyd, 1980; Holsinger, 1996). An important aspect of mating is the ...
A portion of the phylogenetic tree of the squirrel family (Sciuridae) illustrates how promiscuous ancestral species (black dots) gave rise to both monogamous species (blue dots) and polygynous species ...
Researchers have uncovered new insights into the evolution of bird behavior, revealing why certain mating systems persist while others disappear over time. Researchers at Rice University have ...
A species of frog native to the Brazilian Atlantic rainforest is the first amphibian found to mate exclusively with the same two females throughout its breeding season. Fábio de Sá at São Paulo State ...
