Decay of the wood-wide web?

Abstract: The ‘wood-wide web’ holds that all trees in a forest are physically connected belowground by fungi, and that these fungi serve as passive conduits for the beneficial flow of resources and signals among the networked trees. Through these fungal networks, ‘Mother trees’ recognize and warn related seedlings of danger. Though widely appealing and massively popular, I will explain why this story does not survive scientific scrutiny.

Food will be served from 12.00 while the talk starts 12.15.

A spatial journey into the immune system of the fish branchial cavity

Abstract: The constant exposure of the fish branchial cavity to aquatic pathogens causes local mucosal immune responses to be extremely important for their survival. Whereas the organization of the fish mucosal immune system has been perceived as lacking complexity, the recent discoveries of new immune structures within the branchial cavity of the zebrafish show that the reality is more sophisticated than thoughts.
