为了了解是什么让一些物种成功入侵，量化本地和引进地区之间的表现差异，以及在每个地区占据广泛环境条件的种群之间的表现差异是至关重要的。然而，即使是世界上最臭名昭著的入侵物种，也没有这些数据。在此，我们介绍了全球蒜芥菜田间调查，这是一项协调分布的野外调查，旨在利用最少的资源收集单一入侵物种蒜芥菜（Alliaria petiolata）整个分布的性能数据和种质资源。我们选择该物种是因为它的生态影响，在入侵成功的生态学研究中突出，简单的生活史，以及一些遗传和生活史属性，使其适合实验研究。我们制定了标准化的野外调查方案，以估计每个种群的种群规模（面积）和密度、年龄结构、植株大小和繁殖力，以及食草动物和病原体的损害，并收集有代表性的种子样本。在四年的时间里，在来自北美和欧洲16个国家的164名学术和非学术参与者的贡献下，我们收集了来自383个种群的137,811种植物的45,788次测量和计数，以及来自5,000多种植物的种子。所有的田间数据和种子资源将被整理并发布给科学界。我们的目标是建立小叶青藤作为植物入侵生物学的模式物种，并鼓励对其他入侵物种的大规模合作研究。
To understand what makes some species successful invaders, it is critical to quantify performance differences between native and introduced regions, and among populations occupying a broad range of environmental conditions within each region. However, these data are not available even for the world’s most notorious invasive species. Here we introduce the Global Garlic Mustard Field Survey, a coordinated distributed field survey to collect performance data and germplasm from a single invasive species: garlic mustard (Alliaria petiolata) across its entire distribution using minimal resources. We chose this species for its ecological impacts, prominence in ecological studies of invasion success, simple life history, and several genetic and life history attributes that make it amenable to experimental study. We developed a standardised field survey protocol to estimate population size (area) and density, age structure, plant size and fecundity, as well as damage by herbivores and pathogens in each population, and to collect representative seed samples. Across four years and with contributions from 164 academic and non-academic participants from 16 countries in North America and Europe thus far, we have collected 45,788 measurements and counts of 137,811 plants from 383 populations and seeds from over 5,000 plants. All field data and seed resources will be curated for release to the scientific community. Our goal is to establish A. petiolata as a model species for plant invasion biology and to encourage large collaborative studies of other invasive species.
