Genetic, phenotypic, and ecological differentiation indicate a new cryptic and threatened species in the orchid genus Epidendrum from Alcatrazes Island, southeastern Brazil

Journal of Systematics and Evolution, EarlyView.
Epidendrum insularis occurs on the remote Alcatrazes Island in the southeastern Brazilian coast. The description of this new cryptic species was only possible by the joint use of molecular markers, reproductive experiments, flower morphometry, functional traits, and community analysis.

Floral intra‐individual variation differs between morphs and is linked to pollen deposition in self‐incompatible distylous plants

Plant Biology, EarlyView.
For most traits, floral intra‐individual variation was similar between morphs and populations with different pollinator guilds (bees and hummingbirds), potentially facilitating effective pollen transfer in distylous systems. Still, greater variation in corolla length increased pollen deposition in L‐morph flowers in the bee‐pollinated population ...

Planting diversity and density shape native plant survival and community assembly in tropical forest restoration

Restoration Ecology, EarlyView.
Abstract Introduction Forest restoration in Hawaii is underway due to past large‐scale conversion of forests to pastures dominated by invasive grasses. Secondary succession is limited by grass dominance and a lack of native seed rain, making outplanting a viable restoration strategy.

Diel net CO2 exchange of carnivorous Pinguicula is consistent with low‐level CAM photosynthesis

Plant Biology, Volume 28, Issue 6, Page 1813-1819, October 2026.
In carnivorous butterworts (Pinguicula), CO2 uptake occurs primarily in the light via C3 photosynthesis, yet low‐level CAM photosynthesis, including net CO2 dark fixation, significantly improves the carbon balance of plants, especially under water‐deficit conditions.

Ion‐Channel Activity of Characteristic Alkaloids From Uncaria rhynchophylla

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
Eleven characteristic alkaloids with rhynchophylline‐type and corynanthe‐type scaffolds were isolated from Uncaria rhynchophylla and evaluated against Nav1.7, Nav1.5, Cav3.1, and Kv1.5. Corynanthe‐type alkaloids showed stronger inhibition of Nav1.7, Nav1.5, and Cav3.1, whereas Kv1.5 was less sensitive and displayed a distinct response pattern ...
