The absence of large herbivores after the extinction of the dinosaurs changed the evolution of plants. The 25 million years of large herbivore absence slowed down the evolution of new plant species. Defensive features such as spines regressed and fruit sizes increased.
Research team investigates shifts in seasonal development of early-blooming forest plants – herbarium records show climate warming.
Airborne pollen may induce annoying congestion for some, but a new paper shows that these grains may provide a new way of looking at the climate over 300 million years into the fossil record.
For a tropical wildflower first described by scientists in 2000, the scientific name “extinctus” was a warning. The orange wildflower had been found 15 years earlier in an Ecuadorian forest that had since been largely destroyed; the scientists who named it suspected that by the time they named it, it was already extinct. But in a new paper researchers report the first confirmed sightings of Gasteranthus extinctus in 40 years.
Despite their obscurity, gametophytes are vital to our understanding of biodiversity and to the successful implementation of conservation strategies.
Large, open-access database contains 30,252 images, including images of fossil leaves, and will be of potential use to scientists and students.
Researchers Categorized More Than 80,000 Plant Species as Winners or Losers According to Their Ability To Survive as Humans Shape the Future.
A new study involving more than 100 scientists from across the globe and the largest forest database yet assembled estimates that there are about 73,000 tree species on Earth, including about 9,200 species yet to be discovered.
The Genus Calanthe (family Orchidaceae) consists of more than 207 species distributed in both tropical and subtropical regions.
In a new study a team of researchers devises a mathematical model to calculate the minimum habitat size for endangered plant species.
