摘要

导言作物野生近缘植物(CWR)对人类具有重要的社会经济意义,它们拥有广泛的多样性,是不同栖息地的重要元素。Beta vulgaris subsp. maritima ((L.) Arcangeli),又名海甜菜,是栽培甜菜(GP-1)的重要野生近缘种。该分类群对不同环境条件的高度适应性,以及对不同生物和非生物胁迫的耐受性/抗性,使其成为甜菜改良的重要来源。这项工作的目的是分析意大利海甜菜种群保护的原地和异地状况,从而为保护活动和新的采集任务提供指导。方法从不同的数据库中收集野生和基因库中保存的种群地理分布数据,并提交数据质量控制。然后对相关地点的分布、栖息地特征、土地覆盖和使用情况进行了评估,以深入了解这些化武资源多样性所在地区的现状。此外,还评估了意大利保护区内与保护区外的种群存在情况。对记录进行了密度分析,并最终根据受保护品种的数量估算了海甜菜异地保护的充分性。结果 收集到 138 个 B. vulgaris subsp.所考虑的种群中约有 22% 出现在 Natura 2000 网络的保护区内,约有 15% 出现在官方自然保护区名录(EUAP)中记录的地区。保护区内的种群主要分布在自然环境中,而保护区外的种群主要分布在城市和耕地中。对分布和密度分析结果进行比较后发现,在原生境种群所在的地点与最初收集到的非原生境保护品种的地点之间存在一些差距。还应针对保护区外的种群制定 "保护区外管理 "措施,并开展新的采集任务。

In situ occurrence and conservation of Beta vulgaris subsp. maritima ((L.) Arcangeli) in Italy
IntroductionCrop Wild Relatives (CWR) have great socioeconomic importance for humans harbouring a broad spectrum of diversity and being important elements of different habitats. Beta vulgaris subsp. maritima ((L.) Arcangeli), also known as sea beet, is an important CWR of cultivated beets (GP-1). The high adaptability of this taxon to different environmental conditions, as well as its tolerance/resistance to different biotic and abiotic stresses, makes it a vital source for sugar beet improvement. Aim of this work was to analyse the in situ and ex situ status of sea beet population conservation in Italy, so as to guide protection activities and new collecting missions.MethodsGeographical distribution data of populations were that occur in the wild and conserved in genebanks were assembled from different databases and submitted to data quality control. Distribution, habitat characterization, land cover and use of the involved sites were then evaluated to provide insight into the current condition of areas hosting this CWR diversity. The presence of populations within vs. outside Italian protected areas was also evaluated. A density analysis of the records was performed and the adequateness of sea beet ex situ conservation, in terms of number of conserved accessions, was finally estimated.ResultsA collection of 138 B. vulgaris subsp. maritima high quality georeferenced records were obtained, mainly distributed into Mediterranean Biogeographic Region. About 22% of the considered populations occurs in protected sites of the Natura 2000 Network, while about 15% in areas recorded in the Official list of protected natural areas (EUAP). Occurrences within protected areas are founded primarily in natural environments, whereas those outside are mainly located in urban and cultivated areas. The comparison of distribution and density analysis results revealed the presence of several gaps between sites hosting in situ populations and sites where ex situ conserved accessions were originally collected.DiscussionHere presented data indicates that the protection status for sea beet in Italy can be considered only partially adequate; more proactive protection measures should be foreseen to increase the role of protected areas in safeguarding in situ conservation. “Out of reserve management” for populations outside protected areas should also be developed, as well as new collecting missions carried out.

期刊介绍: Frontiers in Ecology and Evolution publishes rigorously peer-reviewed research across fundamental and applied sciences, to provide ecological and evolutionary insights into our natural and anthropogenic world, and how it should best be managed. Field Chief Editor Mark A. Elgar at the University of Melbourne is supported by an outstanding Editorial Board of international researchers. This multidisciplinary open-access journal is at the forefront of disseminating and communicating scientific knowledge and impactful discoveries to researchers, academics and the public worldwide. Eminent biologist and theist Theodosius Dobzhansky’s astute observation that “Nothing in biology makes sense except in the light of evolution” has arguably even broader relevance now than when it was first penned in The American Biology Teacher in 1973. One could similarly argue that not much in evolution makes sense without recourse to ecological concepts: understanding diversity — from microbial adaptations to species assemblages — requires insights from both ecological and evolutionary disciplines. Nowadays, technological developments from other fields allow us to address unprecedented ecological and evolutionary questions of astonishing detail, impressive breadth and compelling inference. The specialty sections of Frontiers in Ecology and Evolution will publish, under a single platform, contemporary, rigorous research, reviews, opinions, and commentaries that cover the spectrum of ecological and evolutionary inquiry, both fundamental and applied. Articles are peer-reviewed according to the Frontiers review guidelines, which evaluate manuscripts on objective editorial criteria. Through this unique, Frontiers platform for open-access publishing and research networking, Frontiers in Ecology and Evolution aims to provide colleagues and the broader community with ecological and evolutionary insights into our natural and anthropogenic world, and how it might best be managed.
