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 ...

No fair looking at the pictures yet. Now, what would you guess to be the most abundant bird in North America? And the male of which species has the most females within the care of its territory? If ...

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 ...

Engineers at Kennedy Space Center are testing the newest in umbilical technology in support of NASA’s Space Launch Initiative (SLI)-a technology development effort to establish reliable, affordable ...

In one of the most comprehensive studies of its kind, Rice researchers analyze how different mating practices shape evolution and survival Researchers at Rice University have uncovered new insights ...
