DATASET: Seasonal dynamics of the nutritive value of temperate forage trees differ among species

This dataset is linked to the paper "Seasonal dynamics of the nutritive value of temperate forage trees differ among species" (Mesbahi et al., under review).The dataset consists of 285 samples of tree leaves from 2015-2017 at 14 sites across France in June, August, and October (i.e. from spring to autumn). We measured seven nutritive characteristics: <i>in vitro</i> dry matter digestibility (IVDMD) and the contents of crude protein (CP), dry matter (DM), neutral detergent fibre (NDF), acid detergent fibre (ADF), acid detergent lignin (ADL), and minerals.The statistical analysis was performed using the R software. It included model selection, ANOVA, and the estimation of marginal means for each characteristic. Subsequently, we clustered the tree species to simplify the presentation of the results for dissemination.<br>
