Parasitic plants conspire to keep hosts alive
The plant that encourages kissing at Christmas is in fact a parasite, and new research reveals mistletoe has an unusual feeding strategy. When two mistletoes invade the same tree, they increase photosynthesis to get the nutrients they need, essentially sharing the tree and causing it less harm. (2021-02-23)

Freeloading orchid relies on mushrooms above and below ground
The orchid species Gastrodia pubilabiata mimics rotting mushrooms or fermented fruit, and is pollinated by fruit flies who mistakenly lay their eggs in its flowers. If there are rotting mushrooms near the orchid, its pollination rate increases. As well as using mushrooms to attract insect pollinators, G. pubilabiata survives by absorbing nutrients from the fungal hyphae of mushrooms. This is the first time a plant has been discovered to depend on mushrooms both above and below ground. (2018-03-22)

Global warming will reduce ocean productivity, marine life
A 10-year, satellite-based analysis has shown for the first time that primary biological productivity in the oceans -- the growth of phytoplankton that forms the basis for the rest of the marine food chain -- is tightly linked to climate change, and would be reduced by global warming. This would cause a rapid, overall reduction in marine life. (2006-12-06)
