Taxonomy and diversity of Marcgraviaceae, north of the São Francisco river, northeast Brazil

Nordic Journal of Botany, EarlyView.
This study provides a comprehensive assessment of Marcgraviaceae species diversity north of the São Francisco river in northeastern Brazil, analyzing species richness and distribution patterns across 384 000 km² of phytogeographic domains. Through field collections, herbarium studies (both physical and digital), and detailed morphological analyses, we ...

A new species of Drimia Jacq. ex Willd. (Asparagaceae) from Nellai wildlife sanctuary, Western Ghats, India

Nordic Journal of Botany, EarlyView.
The new species Drimia courtallensis from the Nellai Wildlife Sanctuary of Tamil Nadu, India is described and illustrated. It is similar to Drimia razii,in its necked bulb, hysteranthous nature, lax inflorescence and diurnal flowers on moderately short pedicels but it can be distinguished by its broader linear‐lanceolate leaves (230–420 × 6–15 mm ...

Hybridization, polyploidy, and evolutionary transitions between monoecy and dioecy in Bryonia (Cucurbitaceae) [PDF]

, 2008
Correns’s 1903 (Berichte der Deutschen Botanischen Gesellschaft 21: 133 – 147) crosses between a monoecious and a dioecious species of Bryonia revealed the simple Mendelian inheritance of dioecy and provided the first instance of an XY sex determination ...

A new species from an inselberg in the Brazilian Atlantic forest: Stachytarpheta forzzae (Verbenaceae), supported by morphological, palynological and anatomical evidence

Nordic Journal of Botany, EarlyView.
We describe Stachytarpheta forzzae, a new species from an inselberg located in the municipality of Guaratinga, state of Bahia, within the Brazilian Atlantic forest. Morphologically, it resembles S. sprucei, the only other species of the genus known to inhabit inselbergs.

High β‐diversity in fig wasp communities driven by species turnover in widely distributed Neotropical fig trees

Oikos, EarlyView.
Wasp communities associated with fig trees, Ficus spp., are a model system to investigate how local and regional processes shape biodiversity across large geographical ranges. We investigated the β‐diversity of fig wasp assemblages associated with three widely distributed Neotropical fig species – F. citrifolia, F. obtusifolia and F. pertusa – using 27

Self-incompatibility in Papaver Pollen: Programmed Cell Death in an Acidic Environment

Journal of Experimental Botany, 2018
Self-Incompatibility (SI) is a genetically controlled mechanism that prevents self-fertilisation and thus encourages outbreeding and genetic diversity.

Floral resource diversity drives spatiotemporal variation in plant–pollinator network structure

Oikos, EarlyView.
Mechanisms underlying community assembly, including those related to species interactions, vary across space and time. Plant–pollinator networks exemplify these dynamics, where link rewiring and turnover mediate adaptations to environmental changes. Bees rely on diverse floral resources (e.g.
