“…8). As found in other species that are also morphologically and genetically distinguishable (Su & al., 2015; Massó & al., 2018), the climatic niche of Cypripedium formosanum is clearly distant from those of the two main geographic ranges of C . japonicum (mainland China + Korea and Japan).…”

To date, little is known about the past evolutionary trajectories of rare and endangered orchids native to mainland China, Japan, and Korea (the CJK region). In this study, we focus on two endangered orchids, Cypripedium japonicum (present in the three countries) and C. formosanum (endemic to Taiwan), to understand the divergence/speciation models that would have been operating in this group, including genetic diversity, geographic structure, and colonization pathways across the region. Using a combination of five cpDNA regions, we reconstructed phylogenetic trees and investigated the genetic diversity/structure of 20 populations. Ecological niche modeling was used to gain insight into the paleodistribution and dispersal corridors at the Last Glacial Maximum and to survey climatic niche differences. Populations from mainland China + Korea, Japan, and Taiwan formed three distinct monophyletic lineages and were placed into separate genetic clusters, agreeing with geographic barriers and species boundaries. Populations of C. japonicum in mainland China harbored the highest diversity, suggesting the presence of multiple glacial refugia. The Korean populations would have originated from either western/central or eastern China, probably using a dispersal corridor across the East China Sea shelf. The divergence of C. formosanum is proposed under an allopatric speciation model, also highly influenced by a climate niche shift. In the context of previous studies, a deep divergence in cpDNA sequences between Chinese + Korean and Japanese populations of C. japonicum may be taken as an example of the speciation events of the CJK flora since the late Neogene that have led to its current species richness.

“…The study of the population genetic structure of plant species, in most cases, narrow Mediterranean endemics (36 of the 78 documents have as focus narrow endemic species), is the current trend [22,55,56]. Médail and Baumel [22] argue that comparative phylogeography across several co-occurring taxa could greatly improve proactive conservation actions for threatened endemic plants within biodiversity hotspots.…”

During the last decades, phylogeography has transformed the ways to analyze and understand plant diversity and biogeography. The repeated and increasingly detailed articles made from DNA data with phylogeographical procedures and algorithms have revolutionized biodiversity research, particularly on biodiversity conservation. This paper presents a systematic literature review of the different ways in which phylogeography has been applied to plants in Mediterranean-type ecosystems (MTEs), especially to rare, threatened, and endemic plants. Studies ranged from basic research to how phylogeography is actually contributing to management conservation of Mediterranean plants. Finally, new and future phylogeography perspectives with integrative scientific arguments and conceptual bases applied to plant conservation biology are discussed.

“…These novel methodologies are also useful to evaluate the validity of morphology as a taxonomic character (e.g., lignotuber state in Eucalyptus L'Hér; Gosper et al, 2018). Taxonomical studies can establish (by describing novel species; e.g., genus Ceanothus L. in California; Burge et al, 2017) or modify the conservation status (Massó et al, 2018) in the case of Cynara baetica (Spreng.) Pau subspecies.…”

The present paper is an overview of state of the art in plant conservation in Mediterranean-type Ecosystems (MTEs), highlighting current studies and neglected topics. A review of the literature dealing with this issue and a general analysis of the results was performed, delving into relevant plant conservation biology topics. The main topics considered were: 1) reproductive biology and genetic conservation, 2) threat factors and effects of global change, and 3) evaluation of conservation status and protected areas selection. This study illustrates differences in the number of documents published in northern countries of the Mediterranean Basin concerning southern and eastern countries and compared with other MTEs. It also highlights the paramount importance of public organizations as funding entities. Additionally, it points to a decrease in traditional subject categories related to plant conservation and increased multidisciplinary conservation research and novel methodologies (e.g., phylogenomics, SDM). To overcome existing biases among the different MTE regions, integrating actions at a transnational level would be necessary, with standard conservation policies and strategies. Moreover, research should be supported with more important participation and funding from private entities, with a clear focus on specific conservation proposals. In contrast, certain weaknesses were detected, some related to the limited information available about threatened plant species and the scarce use of the available data from genetic conservation research in management plans. Consequently, the authors consider that future conservation efforts should be addressed to improve the knowledge of threatened MTEs’ flora and implement a manual of good practices, which would make use of the available research information to put forward more direct proposals for management and conservation.
