Some papers that discuss tree allometry to obtain biomass and sapwood cross sectional area

In order to accurately determine the water budget of trees (see also yesterday's post), it is crucial to establish a connection between the quantity of sapwood and the transpiration rate from the leaves. One essential factor in this process is obtaining accurate measurements of the sapwood cross-sectional areas (CSA). However, it is important to note that these CSA measurements can vary significantly from one plant to another. Acquiring this data can be challenging, and as a result, researchers have conducted studies aiming to establish allometric relationships as a means to estimate these measurements. To assist me in finding relevant literature on this topic, I reached out to my colleague involved in the WATERSTEM project. Below, you will find the literature they recommended.
