Since F. syl- vatica is a shade-tolerant tree species, higher leaf nitrogen concentration in lower light envi- ronment is a strategy of nitrogen partitioning for more efficient [...] higher leaf carbon content and CN ratio than in the understory.

Since light and temperature are generally expected to be strongly correlated, direct effects of light and temperature on herbivory are likely to be confounded [29]. Light is certainly

We kindly ask you to [...] make the most of the online sessions. Before the class: 1. Prepare your working place in advance. It is best to use a laptop or a PC, a tablet may be ok (and may even be good if you can write on it) but [...] but you will learn plenty of interesting maths. You will receive solutions after each class. 7. It is an expectation that students in the camp will be using a camera and a microphone to create a friendly
