Plant populations are not randomly arranged assemblages of genotypes but are structured
in space and time (2, 29, 49, 58, 84, 112). This structure may be manifested among …

Background Floral nectar is an important determinant of plant–pollinator interactions and an
integral component of pollination syndromes, suggesting it is under pollinator-mediated …

Alterations in water availability and drought events as predicted by climate change
scenarios will increasingly impact natural communities with effects already emerging at …

Mimicry is a classic example of adaptation through natural selection. The traditional focus of
mimicry research has been on defence in animals, but there is now also a highly-developed …

Nectar robbers are birds, insects, or other flower visitors that remove nectar from flowers
through a hole pierced or bitten in the corolla. This paper is a review of the effects of nectar …

The development of a bee species as a new crop pollinator starts with the identification of a
pollination-limited crop production deficit and the selection of one or more candidate …

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

(1) The transport of pollen from donor flowers by bumble bees was measured by examining
deposition on stigmata of sequences of recipient flowers. The rate of decay of grain …

This paper reviews recent developments in plant population genetics and evolution. Topics
discussed include: 1) levels of genetic variation within and among populations; 2) gene flow; …

Colony foraging activity of four Melipona species (Apidae: Meliponinae, tribe Meliponini)
was studied during the dry season, when many plants flower in central Panama. The …
