Effects of reduced precipitation and advanced spring phenology on intra- and interspecific competition between beech, oak and linden saplings

This repository contains physiological (leaf δ¹³C, nitrogen), phenological, and growth data from three temperate deciduous tree saplings grown in mesocosms under drought, warmer winters, or combined treatments. Saplings were cultivated in monocultures or two-species mixtures. Measurements span two growing seasons (2022–2023), including spring and autumn phenology, summer physiology (June/August), and growth assessments during winter.

### Files and variables

#### File: Autumn_Phenology.txt

**Description:** This file contains individual-level autumn phenology data for tree saplings grown in an experimental mesocosm setup. Each row represents a single sapling observed in a given year (2022–2023), with variables describ...,
