Data from: Albert et al. (2021) Seed production of co-occurring species: regenerative strategies, plant economic spectrum or architectural constraints? Basic and Applied Ecology

The dataset includes trait measurements and the phylogeny of 56 co-occurring grassland herbs. The phylogeny was constructed using V.PhyloMaker (Jin & Qian 2019, doi: 10.1111/ecog.04434).

Research hypotheses and data collecting are described in the paper: Albert et al. (2021) Seed production of co-occurring species: regenerative strategies, plant economic spectrum or architectural constraints? Basic and Applied Ecology (pending acceptance)

Leaf_size: average species leaf size (log-transformed)
Cyclicity: species cyclicity (indicating shoot lifespan)
Spread: average species lateral spread
Persistence: average species persistence (indicating the persistence of connection between parent and offspring ramets)
Clonal: 0/1 indicating whether a species is clonal or not
Offspring: average species multiplication rate
Longevity: annual vs. perennial
seed_yield: average species seed yield (seed mass * seed number) (log-transformed)

该数据集包含了56种共现草原草本植物的性状测量及其系统发育树。系统发育树系通过V.PhyloMaker软件构建，该软件由Jin与Qian于2019年开发（参考文献：Jin & Qian 2019, doi: 10.1111/ecog.04434）。研究假设和数据收集方法在Albert等人于2021年发表的论文中有详细描述：《共现物种的种子产量：再生策略、植物经济谱系还是建筑约束？》（待接受发表，期刊：Basic and Applied Ecology）。
