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 ...

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 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 ...

In the darkness of old church attics, surprisingly romantic scenes take place as male greater mouse-eared bats (Myotis myotis), the largest native bat species in Europe, compete for the attention of ...

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 ...

Traditional explanations for why some animals are monogamous and others are promiscuous or polygamous have focused on how the distribution and defensibility of resources (such as food, nest sites, or ...
