After a long wait, in April – August we had a one-of-a-kind opportunity to carryout field work. We spent close to two months in the mangroves of Tuxpan, Veracruz, during a dry season never seen before. We monitored sap-flow in root grafted trees and carried out a couple of irrigation experiments- just before a flooding event came at the early start of the rainy season in July.
We also had a hard time with the global crisis. Most of our fieldwork had to be put on hold. Flight bookings were cancelled and well…. we did a lot of video-conferencing. But lucky Hannah was able to visit the mangrove for a few days to start irrigation trials and sap flow monitoring. We hope 2021 will be much better!
It all started in 2015, when an unexpected flooding forced us to adapt and Lupillo came up with the idea of poking roots with a steel rod. In no time after that, we were exploring root graft frequency in a Mexican mangrove forest.
Having all together for the first time was very exiting!. We discussed the synergies of our expertise and defined a working program that will allow us to combine our disciplines in a dynamic innovative way. We also spent some time discussing beer gardens and sun!
From the 31st May to the 5th of June, 2019. Alec and Nadezhda took the lead introducing the team to the uso of the Heat Field Deformation method to measure Sap flow in trees. This method allows to detect the sap flow rate and as well as its direction at a whole tree level.
