The pollination biology of Sauroglossum elatum Lindl. (Orchidaceae : Spiranthinae): moth-pollination and protandry in neotropical Spiranthinae

, 2015
The pollination biology of Sauroglossum elatum Lindl (Orchidaceae: Spiranthinae) was studied in the State of Sao Paulo, south-eastern Brazil. This orchid is protandrous and almost fully self-compatible, but pollinator-dependent.

The Red Queen unveils the sexual and mating strategies of flowers

Journal of Ecology, Volume 114, Issue 5, May 2026.
Although the conventional wisdom is that floral traits of plants evolved in concert with their mutualistic pollinators, here we showed that several key sexual and mating traits of plants, which modulate their outcrossing strategy, evolved in response to the pressure exerted by their antagonistic insect herbivores.

Tracking males and females: investigating protandry throughout the annual cycle in a small migratory songbird

, 2015
Protandry, the phenomenon of males arriving earlier at the breeding grounds than females, has been demonstrated in several migratory bird species. The pattern is linked to reproductive success and often ascribed to selection for securing the highest ...

Geographic, genetic and life-history variability in a sex-changing fish

Frontiers in Marine Science, 2015
Sequential hermaphroditism, commonly referred to as sex change or sex reversal, is a striking phenomenon in mating-system evolution and the most remarkable example of sexual plasticity. Among vertebrates, it is specific to teleosts.

Flower Longevity and Protandry in Two Species of Gentiana (Gentianaceae)

Annals of the Missouri Botanical Garden, 1987
Both Gentiana saxosa and G. serotina are protandrous. When flowers open, pollen is presented extrorsely around the closed stigma for one to six days. As the stigma opens, the stamens curve toward the corolla lobes. The length of the female phase, and therefore reproductive flower life, is determined by pollination, although in both species the corolla ...

Male-biased gonadal differentiation in hatchery-reared blackthroat seaperch Doederleinia berycoides and development of molecular markers to elucidate sex differentiation mechanisms

Frontiers in Marine Science
In the seed production of commercially valuable blackthroat seaperch Doederleinia berycoides, the sex ratio is often skewed toward males. To address this imbalance, several environmental and dietary approaches have been examined; however, the issue ...

Genetic basis of the phenomenon of male sterility and fertility restoration in maize (Zea mays L.) – a review

Agronomy Science
The phenomenon of male sterility in higher plants is, apart from protandry (earlier maturation of stamens), protogyny (earlier maturation of pistils), heterostyly (different stigmas) and self-incompatibility, one of the evolutionarily conditioned ...
