来自全球的研究人员通过分析483个热带树木年轮序列，首次系统评估了1930年以来干旱对热带森林茎生长的长期影响。研究发现，在最干旱的年份中，茎生长仅出现2.5%（95%CI:2.2-2.7%）的微弱下降，且这种下降通常不持续到干旱年后。值得注意的是，裸子植物（gymnosperms）比被子植物（angiosperms）更易受旱季干旱影响，而雨季干旱对后者影响更大。该研究揭示了热带森林碳汇功能对历史 ...

Angiosperms (flowering plants) are the most diverse of all major lineages of land plants and the dominant autotrophs in most terrestrial ecosystems. Their evolutionary and ecological appearance is ...

This large comparative phylogenetic study across angiosperms shows that species that are herbaceous or have small conduits evolved these traits before colonizing environments with freezing ...

Results of the study, titled "Dosage Sensitivity Shapes Balanced Expression and Gene Longevity of Homoeologs after Whole-Genome Duplications in Angiosperms," were published in The Plant Cell.

There are two main types of plants: flowering plants, known as angiosperms, and non-flowering plants, known as gymnosperms. The flower bud and fruit in the fossil are both clear indicators that F ...

Flowering plants (angiosperms) are the largest, most diversified, and most successful major lineage of green plants, with ~330,000 known species.

Then, about 125 million years ago, angiosperms and their flowers sprang forth during the Cretaceous period, as fully formed as Aphrodite. Within 30 million years, angiosperms would dominate the Earth.

The surviving angiosperms got a boost from changes to the soil. The impact pulverized a great deal of rock and spread the mineral-rich dust all over the planet, including iron that enriched the soil.

This contrasts starkly with the evolutionary tree of dinosaurs. “Non-avian dinosaurs lost so many species, they lost entire lineages, which we don’t see in angiosperms,” Dr. Thompson said.
