OCBIL theory aims to develop an integrated series of hypotheses explaining the evolution
and ecology of, and best conservation practices for, biota on very old, climatically buffered …

Most flowering plants are hermaphroditic, yet the proportion of seeds fertilized by self and
outcross pollen varies widely among species, ranging from predominant self-fertilization to …

Of paramount importance to the natural sciences, the principles of Darwinism, which involve
variation, inheritance, and selection, are increasingly of interest to social scientists as well …

Flowering plants possess an unrivaled diversity of mechanisms for achieving sexual and
asexual reproduction, often simultaneously. The commonest type of asexual reproduction is …

Although they are relative latecomers on the evolutionary scene, having emerged only 135?
170 million years ago, angiosperms—or flowering plants—are the most diverse and species …

Background Analyses of speciation genes–genes that contribute to the cessation of gene
flow between populations–can offer clues regarding the ecological settings, evolutionary …

Flowering plants display spectacular floral diversity and a bewildering array of reproductive
adaptations that promote mating, particularly outbreeding. A striking feature of this diversity …

Red flower color has arisen multiple times and is generally associated with hummingbird
pollination. The majority of evolutionary transitions to red color proceeded from purple …

Background Some of the most exciting advances in pollination biology have resulted from
interdisciplinary research combining ecological and evolutionary perspectives. For example …

Variation in natural selection across heterogeneous landscapes often produces (a) among‐
population differences in phenotypic traits,(b) trait‐by‐environment associations, and (c) …
