Abstract

Questions

Can we reconcile regional and European classifications of anthropogenic plant communities at the biogeographical scale? How are these communities characterized by species origins, traits and ecological preferences?

Location

Atlantic territories in the NW Iberian Peninsula (a.k.a. Cantabrian Mixed Forests ecoregion); south-western Europe.

Methods

We classified 2508 plots with the aim of being consistent with regional phytosociological expertise, while matching that expertise with current EuroVegChecklist alliances. We used modified TWINSPAN to revise the original phytosociological classification, followed by semi-supervised re-classification of the whole dataset. We determined the proportion of natives, archaeophytes, and neophytes. We also described the alliances in terms of species traits (lifeforms, height, and flowering phenology) and ecological requirements (temperature, moisture, light, nutrients, soil reaction, disturbance frequency, and severity).

Results

We assigned 2086 vegetation plots to 25 anthropogenic alliances representing nine vegetation classes (Cymbalario-Parietarietea diffusae, Polygono-Poetea annuae, Papaveretea rhoeadis, Digitario sanguinalis-Eragrostietea minoris, Chenopodietea, Sisymbrietea, Bidentetea, Artemisietea vulgaris, and Epilobietea angustifolii). The plots included 1149 species: 78% natives, 15% archaeophytes and 7% neophytes. Vegetation groups were organized along a principal axis of abiotic stress (dry-sunny to moist-shady habitats) and a secondary axis of disturbance.

Conclusions

In the Iberian Atlantic territories, anthropogenic habitats host one third of the regional plant species pool and one fifth of the Iberian flora. Mesic perennial ruderal vegetation is especially rich in native species and can be a biodiversity asset in urban landscapes. Our biogeographical-level synthesis can improve the management of anthropogenic plant communities and contribute towards a European-level synthesis of human-made vegetation.

伊比利亚半岛西北部人为植物群落的分类与特征

我们能否在生物地理尺度上协调区域和欧洲的人为植物群落分类？这些群落如何以物种起源、特征和生态偏好为特征？位于伊比利亚半岛西北部的大西洋地区（又名坎塔布里亚混交林生态区）；欧洲西南部。方法我们对2508个地块进行分类，目的是与区域植物社会学专业知识保持一致，同时将这些专业知识与当前的EuroVegChecklist联盟相匹配。我们使用改进的TWINSPAN对原始的植物社会学分类进行修正，然后对整个数据集进行半监督重新分类。我们确定了原生生物、古植物和新生植物的比例。我们还从物种特征（生命形式、高度和开花物候）和生态要求（温度、水分、光照、养分、土壤反应、干扰频率和严重程度）方面描述了这些联盟。结果将2086个植被样地划分为25个人工联盟，代表9个植被类（Cymbalario-Parietarietea diffusae、Polygono-Poetea annuae、Papaveretea rhoeadis、Digitario sanguinalis-Eragrostietea minoris、Chenopodietea、Sisymbrietea、Bidentetea、Artemisietea vulgaris和Epilobietea angustifolii）。样地共有植物1149种，其中原生植物78%，古植物15%，新生植物7%。植被群沿非生物胁迫的主轴（干日照到湿阴生境）和扰动的次轴组织。结论：在伊比利亚大西洋地区，人类栖息地拥有三分之一的区域植物物种库和五分之一的伊比利亚植物区系。Mesic多年生乡土植被尤其具有丰富的本地物种，可以成为城市景观的生物多样性资产。我们的生物地理水平的综合可以改善人为植物群落的管理，并有助于欧洲水平的人造植被综合。

期刊介绍： Applied Vegetation Science focuses on community-level topics relevant to human interaction with vegetation, including global change, nature conservation, nature management, restoration of plant communities and of natural habitats, and the planning of semi-natural and urban landscapes. Vegetation survey, modelling and remote-sensing applications are welcome. Papers on vegetation science which do not fit to this scope (do not have an applied aspect and are not vegetation survey) should be directed to our associate journal, the Journal of Vegetation Science. Both journals publish papers on the ecology of a single species only if it plays a key role in structuring plant communities.
