Long-term study of Geranium sylvaticum L.
In ecology, although there is a demand for it, there are very few long time series. So, after finishing the fieldwork for my master thesis in 1995, I decided to keep 90 of the Geranium sylvaticum L. individuals and continue to follow them up on a yearly basis, looking at between year variations as well as long-term trends. Every summer since 1995 I have measured; investments in reproduction (number of flowers, number of fruits, fruit:flower ratio, number of seeds) and vegetative growth (number of stalks and the height, number of leaves).
