A network of scientists across the globe have identified more than 700 plant genera named for women. This is a nearly 20-fold increase in the number of genera linked to women before the group started working on the list.
An team botanists has analyzed the morphological diversity of fossilized flowers and compared it with the diversity of living species. Their results were quite exciting: Flowering plants had already produced a large number of different flower types shortly after their emergence in the Cretaceous period, and this earliest floral diversity was greater than that today.
A new paper reveals that researchers have found unaltered agave plant species cultivated by several early cultures including the Hohokam people, a large Native American group in the Southwest that existed between 300 and 1500 CE.
Researchers study track how “flower power” survived mass extinction 66 million years ago to become the dominant plant type.
A long-lived monocarpic species of bamboo, Phyllostachys nigra var. henonis, only flowers once every 120 years before it dies. The upcoming flowering event for this species does not bode well for its continued long-term survival, as most flowers are not producing viable seeds.
An international group of scientists has issued an urgent call for coordinated action to save the iconic genus Rafflesia, which contains the world’s largest flowers. This follows a new study which found that most of the 42 species are severely threatened, yet just one of these is listed in the International Union for Conservation of Nature (IUCN)’s Red List of Threatened Species. Furthermore, over two thirds (67%) of the plants’ habitats are unprotected and at risk of destruction.
Retention of dead biomass by plants is common in the temperate herbaceous flora and can be related to certain plant traits, indicating relevance to ecosystem functioning. These are the main findings of an experimental study on more than 100 plant species jointly performed by researchers from the Germany and Czech Republic.
A research team has unraveled the evolutionary history of the Arctic flora. Researchers selected 32 angiosperm clades comprising 3,626 species across the angiosperm tree of life. They found that dispersal to the Arctic and in situ diversification within the Arctic followed similar trends through time.
New research looking at the evolution of terrestrial orchid species has found that global cooling of the climate appears to be the major driving factor in their diversity. The results help scientists understand the role of global climate on diversity of species, and how our current changing global climate might affect biodiversity in the future.
