Hunting is changing forests, but not as expected
In many tropical forests, over-hunting is diminishing the populations of animals who are vital for dispersing the seeds of woody plants. Those same plants are vital for carbon storage and previous theoretical modeling studies predicted dire consequences to defaunation, this research suggests otherwise. Instead the data shows the effects on the ecosystem are less straightforward and less immediately devastating. (2018-02-15)

How do plants protect themselves against sunburn?
To protect themselves against UV-B, which are highly harmful, plants have developed cellular tools to detect them and build biochemical defenses. A team of Swiss biologists discovered the existence of a UV-B receptor a few years ago. Today, these researchers demonstrate how these receptors, once activated by UV-B, associate with proteins that assist them to be assembled in the cell nucleus and to develop responses for survival and acclimation.

When the seed becomes a plant, it has 48 hours to survive
During germination, the embryo within the seed must develop into a young seedling capable of photosynthesis in less than 48 hours. During this time, it relies solely on its internal reserves, which are quickly consumed. It must therefore rapidly create functional chloroplasts, cellular organelles that will enable it to produce sugars to ensure its survival. Researchers from the universities of Geneva and Neuchâtel, Switzerland, have revealed the key elements that control this process. (2018-08-02)
