    The analysis of plant elemental composition and the underlying factors affecting its variation are a current hot topic in ecology. Ecological adaptation to atypical soils may shift plant elemental composition. However, no previous studies have evaluated its relevance against other factors such as phylogeny, climate or individual soil conditions. We evaluated the effect of the phylogeny, environment (climate, soil), and affinity to gypsum soils on the elemental composition of 83 taxa typical of Iberian gypsum ecosystems. We used a new statistical procedure (multiple phylogenetic variance decomposition, MPVD) to decompose total explained variance by different factors across all nodes in the phylogenetic tree of target species (covering 120 million years of Angiosperm evolution). Our results highlight the relevance of phylogeny on the elemental composition of plants both at early (with the development of key preadaptive traits) and recent divergence times (diversification of the Iberian gypsum flora concurrent with Iberian gypsum deposit accumulation). Despite the predominant phylogenetic effect, plant adaptation to gypsum soils had a strong impact on the elemental composition of plants, particularly on sulphur concentrations, while climate and soil effects were smaller. Accordingly, we detected a convergent evolution of gypsum specialists from different lineages on increased sulphur and magnesium foliar concentrations.Spanish Government CGL2015-71360-P PID2019-111159GB-C31European Commission H2020-MSCA-RISE-777803Spanish Government BES-2016-076455PTA contract AEI-CSIC PTA2019-017033-I/AEI/10.13039/501100011033Ramon y Cajal Fellowship (MICINN) RYC-2013-1416

    This study has been made possible by the long-time experiences of the many research projects awarded to the authors. Especially, the projects 'Assessment, Monitoring and Applied Scientific Research for Ecological Restoration of Gypsum Mining Concessions (Majadas Viejas and Marylen) and Spreading of Results (ECORESGYP) ' sponsoredby the company EXPLOTACIONES RiO DE AGUAS S.L. (TORRALBA GROUP) ; 'Provision of services, monitoring and evaluation of the environmental restoration of the mining concessions Los Yesares, Maria Morales and El Cigarron' sponsored by the company Saint Gobain Placo Iberica S.A.; and 'CEIJ-009 Integrated study of coastal sands vegetation (AREVEG II) ' sponsored by CEI.MAR. We are very grateful to the three reviewers for their comments and suggestions, which have been very helpful in improving the manuscript.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.company Saint Gobain Placo Iberica S.A.CEI.MARcompany EXPLOTACIONES RiO DE AGUAS S.L.

    Background: One of the most common complaints among menopausal women concerns changes in sexual function. This is attributed to various factors, including anatomical defects in the genital tract, with pelvic organ prolapse (POP) being one of the most prevalent problems affecting women during this stage of their lives. Additionally, symptoms resulting from gonadal hypofunction can also contribute to the development of sexual dysfunction during menopause. This research aimed to explore the way in which postmenopausal patients with POP experienced their sexuality in our setting. Methods: To achieve the proposed objective, we conducted a descriptive, crosssectional study involving a total of 133 postmenopausal women with POP. Results: The results of our series are consistent with the scarce literature available in our setting and suggest a high rate of sexual dysfunction in postmenopausal patients with POP. Conclusions: We can conclude that POP is associated with the presence of female sexual dysfunctio

    The Fate of Endemic Species Specialized in Island Habitat under Climate Change in a Mediterranean High Mountain

    Mediterranean high-mountain endemic species are particularly vulnerable to climatic changes in temperature, precipitation and snow-cover dynamics. Sierra Nevada (Spain) is a biodiversity hotspot in the western Mediterranean, with an enormous plant species richness and endemicity. Moehringia fontqueri is a threatened endemic plant restricted to north-facing siliceous rocks along a few ridges of the eastern Sierra Nevada. To guide conservation actions against climate change effects, here we propose the simultaneous assessment of the current reproductive success and the possible species’ range changes between current and future climatic conditions, assessing separately different subpopulations by altitude. Reproductive success was tested through the seed-set data analysis. The species’ current habitat suitability was modeled in Maxent using species occurrences, topographic, satellite and climatic variables. Future habitat suitability was carried out for two climatic scenarios (RCP 2.6 and 8.5). The results showed the lowest reproductive success at the lowest altitudes, and vice versa at the highest altitudes. Habitat suitability decreased by 80% from current conditions to the worst-case scenario (RCP 8.5). The lowest subpopulations were identified as the most vulnerable to climate change effects while the highest ones were the nearest to future suitable habitats. Our simultaneous assessment of reproductive success and habitat suitability aims to serve as a model to guide conservation, management and climate change mitigation strategies through adaptive management to safeguard the persistence of the maximum genetic pool of Mediterranean high-mountain plants threatened by climate change

    The Role of Technology in Greenhouse Agriculture: Towards a Sustainable Intensification in Campo de Dalías (Almería, Spain)

    Get PDF
    Campo de Dalías, located in southeastern Spain, is the greatest European exponent of greenhouse agriculture. The development of this type of agriculture has led to an exponential economic development of one of the poorest areas of Spain, in a short period of time. Simultaneously, it has brought about a serious alteration of natural resources. This article will study the temporal evolution of changes in land use, and the exploitation of groundwater. Likewise, this study will delve into the technological development in greenhouses (irrigation techniques, new water resources, greenhouse structures or improvement in cultivation techniques) seeking a sustainable intensification of agriculture under plastic. This sustainable intensification also implies the conservation of existing natural areas

    Conservation and Phylogeography of Plants: From the Mediterranean to the Rest of the World

    Get PDF
    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
