چکیده

canopy density is linked to weaker or no thermophilisation. By offering more shadow, it appears, the trees are shielding the ground vegetation from the temperature rise. “We believe that the effect of the tree canopy is to moderate changes in temperature at the lower levels in the wood — particularly where, as is the case in much of Europe, woods have been becoming denser and shadier in recent years,” Keith Kirby from Oxford University explained in a press statement. While this suggests that, at least for some forests, the trend goes in the direction that will mitigate effects of climate change in modest ways, the authors also warn that largescale harvesting of biomass for biofuel production could open up the canopies more and thus remove the protection for the ground vegetation, which in turn also provides habitat for many other species, including pollinating insects. All in all, if we want the forests to help us fight climate change, we will have to help them survive first. Unlike the children in the times of the Grimm brothers, who were conditioned to fear the forests, the next generations will face the fear of having to survive without forests.

Hydraulic microelectrode advancermade by David Hubel. David Hubel was a giant in our field, yet he waswarm, friendly, and humble in person. He and Torsten Wiesel, following in the footsteps of their mentor Steve Kuffler, discovered fundamental principles of information processing in the brain and fundamental principles of how the brain wires itself up. I think many people in the field see David...
