Cultivation of Jatropha shows the importance of conservation

Jatropha curcas could be an oil crop with major biofuel potential, but the breeding germplasm has little variation. Botanists have found that there is genetic potential in previously overlooked non-toxic jatropha, but it needs conservation.

Bromeliads going batty: pollinator partitioning among sympatric chiropterophilous Bromeliaceae

Sympatric flowering species must frequently share pollinators. Pollinators can be a limited resource for the sexual reproduction of a plant, and such sharing could...

Aridification as driver of plant evolution

Aridification has been a major force in cycad evolution, says José Said Gutiérrez-Ortega. It helps to explain why cycads were capable to adapt and diversify in the modern habitats, even when they originated in the early evolution of land plants.

Archaeologists surprised by large maize at El Gigante

The discovery of ancient large maize corn cobs at the El Gigante rockshelter might change how we think about the earliest complex societies in Central America.

Biomechanics of rhizophores in Rhizophora mangroves

Rhizophora mangle supports a thinner stem of higher mechanical resistance when compared to Avicennia germinans, a co-existing mangrove lacking rhizophores.

Biodiversity flourishes in an ancient rubbish tip

The preservation of archeological sites does not always overlap with the conservation of biodiversity. At the most basic level, the United Nations Educational, Scientific,...

Plant species that survived the K–Pg extinction event had fast-growth ecological strategies corresponding to high assimilation rates & low carbon investment

Halloween Special: First record of bat-pollination in Tillandsia

Bats are responsible for pollinating several species of plants. A new paper in Annals of Botany reports for the first time bat-pollination of a...
