Lost South American wildflower named “extinctus” rediscovered (but still endangered)

By | Botany, News, Plant Science

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.

Science-based policy-making: New recommendations for forest pests and diseases management

By | Forestry, News

Over the last century, emerging diseases have progressively been recognized by the scientific community as the main threat to forest ecosystems. With increasing international trade and globalization, the introduction of non-native species into new environments has exacerbated the problems of emerging pests and diseases worldwide. Additionally, other factors, such as climate change, further complicate matters by altering host-pathogen interactions, thus promoting the spread of diseases caused by native or non-native pathogens.

Fitness needs the right timing: researchers study molecular components of the endogenous clock in the green lineage

By | News, Plant Science

Life on Earth runs in 24-hour cycles. From tiny bacteria to human beings, organisms adapt to alterations of day and night. External factors, such as changes in light and temperature, are needed to entrain the clock. Many metabolic processes are controlled by the endogenous clock. Scientists have now studied the molecular rhythms of the endogenous clock in the “green lineage”.
