Abstract

Motivation

Plant establishment is the result of sequential demographic processes, namely post-dispersal seed survival, seed germination, seedling survival and sapling survival. These processes can be quantified as transition probabilities between life stages through field experiments, and their product provides an overall establishment probability. This information is essential to understand demography within populations and plant colonization potential under global change scenarios. The Mediterranean Region constitutes a biodiversity hotspot characterised by severe summer droughts, which suppose a critical demographic bottleneck for perennial plant establishment. Despite many studies have quantified transition probabilities of woody species in this region, information is scattered through the literature and has not yet been compiled. To fill this gap, we collated data from a systematic literature review and completed them with new unpublished data to create the EstablishMed dataset.

Main types of variables contained

EstablishMed is a compilation of 4728 records of transition probabilities that quantify demographic processes operating during plant establishment. All records belong to native species and were obtained in situ under field conditions. Each record includes information about the specific spatiotemporal context of the study (i.e., year, site, population, habitat and microhabitat) and the experimental procedures employed (e.g., degree of protection against natural enemies). In addition, we included taxonomic and trait information of the study species (i.e., seed mass, dispersal syndrome and life form), and the bioclimate of the study sites.

Spatial location and grain

The dataset covers the whole Mediterranean Region. The finest spatial resolution corresponds to microhabitat types within populations.

Time period and grain

Data were extracted from 271 studies originated between 1991 and 2024.

Major taxa and level of measurement

134 woody species from 80 genera and 39 families.

Software format

EstablishMed is available in .csv format in Dryad repository.

地中海地区木本植物种植过渡概率数据集 EstablishMed

植物成活是连续人口统计过程的结果，即散播后种子存活、种子发芽、幼苗存活和树苗存活。这些过程可以通过实地实验量化为生命阶段之间的过渡概率，它们的乘积提供了总体建群概率。这些信息对于了解种群内部的人口分布以及全球变化情景下的植物殖民潜力至关重要。地中海地区是生物多样性热点地区，夏季干旱严重，是多年生植物生长的关键人口瓶颈。尽管许多研究对该地区木本物种的过渡概率进行了量化，但相关信息散见于文献中，尚未汇编成册。为了填补这一空白，我们整理了系统性文献综述中的数据，并将其与未发表的新数据相结合，创建了 EstablishMed 数据集。

期刊介绍： Global Ecology and Biogeography (GEB) welcomes papers that investigate broad-scale (in space, time and/or taxonomy), general patterns in the organization of ecological systems and assemblages, and the processes that underlie them. In particular, GEB welcomes studies that use macroecological methods, comparative analyses, meta-analyses, reviews, spatial analyses and modelling to arrive at general, conceptual conclusions. Studies in GEB need not be global in spatial extent, but the conclusions and implications of the study must be relevant to ecologists and biogeographers globally, rather than being limited to local areas, or specific taxa. Similarly, GEB is not limited to spatial studies; we are equally interested in the general patterns of nature through time, among taxa (e.g., body sizes, dispersal abilities), through the course of evolution, etc. Further, GEB welcomes papers that investigate general impacts of human activities on ecological systems in accordance with the above criteria.
