The world's first flowers were pollinated by insects, says new study

Plants existed on Earth for hundreds of millions of years before the first flowers bloomed. But when flowering plants did evolve, more than 140 million years ago, they were a huge evolutionary success.

What causes decline of tropical seagrass meadows?

Seagrass, a group of aquatic angiosperms, grows in shallow waters in the coastal sea and contributes most of the primary production while participating in many important ecological processes. Heat stress threatens the survival ...

New study challenges age-old conjecture that bilaterally symmetrical flowers increase pollination accuracy by animals

In nature, flowers may share morphological features, even across distantly related species. Bilateral symmetry is one such feature found in flowers of various taxa, such as orchids and legumes. Animals enter these bilaterally ...

Quantifying climate conditions for the formation of coals and evaporites

Coals were originally formed from plants that require plenty of water or precipitation. Thus, regions with coal were wet and warm. In contrast, evaporites were formed in arid and hot regions where evaporation is strong. Therefore, ...

Study: Diversity of present tree species is shaped by climate change in the last 21,000 years

A research team led by Aarhus University, Denmark, in collaboration with researchers from more than 50 research institutes around the world, has assessed how past climate changes have affected how the composition of tree ...

Study determines criteria for differentiating a pollinating insect from a presumed pollinator in the fossil record

Insect pollination is a decisive process for the survival and evolution of angiosperm (flowering) plants and, to a lesser extent, gymnosperms (without visible flower or fruit). There is a growing interest in studies on the ...

Investigations into factors controlling growth and lignin synthesis in spruce

Norway spruce is a large coniferous tree native to Northern, Central, and Eastern Europe. Conifers make up a considerable portion of the terrestrial biomass and serve as a significant carbon sink, with the majority of the ...
