A primary study of breeding system of Ziziphus jujuba var. spinosa
Ziziphus jujuba var. spinosa has been used as a windbreak and for soil conservation and water retention. Previous studies focused on pharmacological effects and extraction of chemical components in this species, and very few explored the breeding system.

Testing the Adaptive Significance of Personate Flowers in Penstemon (Plantaginaceae)
Floral diversity across plant lineages reflects evolutionary shifts in mating strategy and pollinator specificity. The genus Penstemon contains a handful of species that display personate flowers—a peculiar bee‐pollinated floral type characterized by an upward bulge in the ventral portion of the corolla tube that obstructs the floral opening.

Functional Herkogamy and Pollination Biology in Passiflora cincinnata Mast.
Fruit production in passionfruit species is primarily associated with cross-pollination, but the role of herkogamy, the spatial separation between stigmas and anthers, in reproductive success remains poorly understood.

The Red Queen unveils the sexual and mating strategies of flowers
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.

No evidence for missed mutualists in an invasive plant with the buzz pollination syndrome
Abstract The missed mutualist hypothesis predicts that the absence of mutualistic partners poses a barrier to introduced species becoming invasive. Yet, some alien plants thrive despite potential dependence on certain pollinators. For example, buzz‐pollinated plants typically have specialist floral morphologies and benefit from buzz pollinator behavior

Amorphophallus titanum (Becc.) Becc. (Araceae) is native to the rainforests of Sumatra, and famously produces a single, massive, thermogenic, and highly odoriferous inflorescence. Despite having both male and female flowers in close proximity, A. titanum does not readily self‐pollinate as it is strictly dichogamous, with female flowers receptive on the

In this study, we demonstrate that urbanization intensity reduces the abundance of stem galls on Turnera subulata, while increased vegetation cover and plant vigor promote higher occurrence and abundance. These findings highlight the importance of native vegetation in sustaining specialized insect‐plant interactions and provide evidence that plant ...

Distylous traits in Cordia dodecandra and Cordia sebestena (Boraginaceae) from the Yucatan Peninsula
Distyly is a genetically-controlled polymorphism with two floral morphs exhibiting spatial, reciprocal separation between stigmas and anthers; one morph has long styles and short stamens and the other short styles and long stamens.

Pollination and plant reproduction in the Cerrado, the world's most biodiverse savanna
ABSTRACT The Brazilian Cerrado is a continental‐wide biodiversity hotspot and the most species‐rich savanna ecosystem in the world. The main aspect characterising this biodiversity is that the landscape is arranged as an intricate mosaic of different plant formations, including grasslands, savannas, and forests, each harbouring distinct but ...

Summary Ecological network approaches have advanced our understanding of how species interactions influence community and evolutionary dynamics. However, a key limitation is that most network analyses rely solely on visitation data, often overlooking functional aspects of interactions.
