Contraceptive Care Disparities Among Sexual Orientation Identity and Racial/Ethnic Subgroups of U.S. Women: A National Probability Sample Study.

Sexual minority women may use contraception for various reasons but face notable barriers to contraceptive care, including stigma and discrimination. However, studies examining sexual orientation disparities in contraceptive care have largely relied on nonprobability samples of predominately White women and may thus not be generalizable to U.S.

Modularity increases rate of floral evolution and adaptive success for functionally specialized pollination systems.

Angiosperm flowers have diversified in adaptation to pollinators, but are also shaped by developmental and genetic histories. The relative importance of these factors in structuring floral diversity remains unknown. We assess the effects of development, function and evolutionary history by testing competing hypotheses on floral modularity and shape evolution in Merianieae (Melastomataceae).

Beyond buzz-pollination - departures from an adaptive plateau lead to new pollination syndromes.

Pollination syndromes describe recurring adaptation to selection imposed by distinct pollinators. We tested for pollination syndromes in Merianieae (Melastomataceae), which contain bee- (buzz-), hummingbird-, flowerpiercer-, passerine-, bat- and rodent-pollinated species. Further, we explored trait changes correlated with the repeated shifts away from buzz-pollination, which represents an 'adaptive plateau' in Melastomataceae.
