Ants commonly visit flowers seeking for food resources such as nectar. However, only eight species of orchids are known for having an effective pollinaria removal by ants. In this study, the visit of the orchid Neotinea maculata (Desf.) Stearn by ants is described in one of the three known populations from the province of Valladolid (Spain). Through direct observation, six minor worker ants of Temnothorax exilis (Emery, 1869) (Hymenoptera: Formicidae) group were found visiting flowers of six plants of N. maculata, and four of them were carrying pollinaria on their heads. Other insects were not observed with pollinaria or visiting the flowers. Overall, we found that 33.3% of all the flowers had no pollinaria (96 flowers without pollinaria in a total of 288 flowers). Nevertheless, despite ants observed in the field only promoted cross-pollination between flowers of the same individual (geitonogamy), there is a possibility that the ant will visit another plant’s inflorescence. Thus, ants could be considered not only as visitors but also as true pollinators of N. maculata.

We performed a five-year assessment of the natural vegetation restoration capacity following the 2012 fires in Valdemaqueda (Madrid, Spain) via the characterization of the post-fire and residual vegetation and the analysis of soil physico-chemical characteristics. Six pilot-plots were established in the affected site. Forest species, representative of the potential natural vegetation of the area (Juniperus oxycedrus subsp. lagunae and Quercus rotundifolia woodlands) and broom shrubs (Cytisus scoparius, Retama sphaerocarpa) were planted to assess the relationship among the stages of ecological succession, competition, and soil restoration processes following devastating fire events. The fire-driven alteration of the soil’s physico-chemical properties was evident, given the increased pH and reduced C/N ratio in the first years of the study. However, we observed an increased soil enrichment in the last years of study, accompanied by the propagation of herbaceous species, su[1]pporting our seed bank findings, showing a clear difference in the sprouting rate between burnt and control plots (80% vs. 20%, respectively). The establishment of robust, pyrophyte shrub species (Cistus ladanifer, C. laurifolius, Rosmarinus officinalis) rather than natural succession evidenced the clear conversion of the vegetation in burnt areas. These findings in the pilot-plots allowed evidencing the high vulnerability of the natural vegetation to the settling of pyrophytes, given their low survival rate under the strong competitive pressure of these pyrophytic species. The proliferation of these pyrophytes could translate into changes in soil macro- and microbiota, nutrient dynamics, species diversity, and interaction, added to the alteration of fire regimes in the area. Overall, these results highlight the risk for soil impoverishment and possible erosion of the fire-affected sites. Moreover, they underline the importance of the establishment and regeneration of Genisteae species to outcompete pioneer pyrophytic species, favoring the restoration of the area’s potential natural vegetation

Astragalus edulis (Fabaceae) is an endangered annual plant species from the western Mediterranean region. It occurs in the Iberian Peninsula (SE), Morocco (two main locations in the NE and SW), and the easternmost Canary Islands (Lanzarote and Fuerteventura). After a thorough study assessing genetic diversity and phylogeographic patterns, and a proposal of a management plan to preserve the genetic diversity across the entire area of the species, it is about time to go further in the species conservation. It is necessary to recognize genetically impoverished populations to be able to successfully reinforce populations and find realistic places for translocations. For this, Nei’s genetic diversity values were calculated for the three geographic areas and for their populations. Diversity values were further evaluated to calculate the optimal contribution for the populations within each area to maximize the genetic pool. To evaluate whether the optimum habitat for the species is expected to grow or decrease under a climate change scenario, the optimal model of current climatic suitability of A. edulis was projected into the IPCC (2070_RCP8.5) future scenario. The different geographical areas showed similar genetic diversity values. The populations that contribute to maximize the genetic pool in each geographic area were similar, but not equal, to those proposed in previous studies. The future potential habitat for the species shows a significant range decline, which will affect translocation efforts.

Carici-Genistetea lobelii Klein 1972 corresponds to cyrno-sardinian oromediterranean cushion scrub and related grasslands. In France, this class is only present in Corsica and the syntaxonomic scheme is debated among phytosociologists. The aim of this paper is to highlight the main plant associations of Carici-Genistetea lobelii Klein 1972 and to define the diagnostic species for each phytosociological unit. We compiled 519 vegetation plots and we applied EuropeanVegetationChecklist expert system for the classes of European vegetation to retain only vegetation plots belonging to Carici-Genistetea lobelii. We obtained a dataset with 189 vegetation plots and we classified them with Modified TWINSPAN classification. Our analyses recognized 6 plant associations and 3 sub-associations already described in the literature; and to describe a new alliance corresponding to the supra-mediterranean vegetations (Genistion salzmannii), a new association (Brimeuro fastigiatae-Juniperetum nanae) and its sub-association (alnetosum suaveolentis). For each of them, we identified diagnostic, constant and dominant species and produced their distribution map. Formal definitions were then written for each phytosociological unit (from subassociation to class) and grouped in an expert system to automatically classify the vegetations of Carici-Genistetea lobelii.
Carici Genistetea lobelii Klein 1972对应于cyrno sardinian或地中海垫灌丛和相关草原。在法国，这一类只存在于科西嘉岛，植物社会学家对其句法组合方案进行了辩论。本文的目的是强调Carici Genistetea lobelii Klein 1972的主要植物组合，并定义每个植物社会学单元的诊断物种。我们编制了519个植被地块，并将欧洲植被清单专家系统应用于欧洲植被类别，仅保留属于Carici Genistetea lobelii的植被地块。我们获得了一个包含189个植被地块的数据集，并用改进的TWINSPAN分类法对其进行了分类。我们的分析确认了文献中已经描述的6个植物关联和3个子关联；并描述了一个对应于超地中海植被的新联盟（Genistion salzmannii）、一个新的协会（Brimeuro fastgiatae Juniperetum nanae）及其亚协会（alnetosum suaveolentis）。对于它们中的每一个，我们都确定了诊断性、恒定性和优势物种，并绘制了它们的分布图。然后为每个植物社会学单元（从子关联到类别）编写正式定义，并在专家系统中进行分组，以自动对Carici Genistetea lobelii的植被进行分类。

Geum atlanticum is a species described from North Africa and later found in Southern Iberian Peninsula. However, according to Flora iberica taxonomic treatment, it has been considered synonymous with G. sylvaticum, a species mainly distributed by Southeast of France, Iberian Peninsula, and North of Africa, sharing part of the distribution range and habitat. In this work, herbarium specimens of both G. atlanticum and G. sylvaticum were revised to evaluate morphological differences. Furthermore, the nuclear ribosomal ITS spacer was sequenced to study phylogenetic relationships among G. atlanticum and Iberian Geum species. The morphological study indicated clear differences with G. sylvaticum, and the phylogenetic analysis suggests that G. atlanticum was sister to G. sylvaticum. However, it shared several mutations with other Iberian Geum species. The number of populations is relatively low in the Iberian Peninsula, so its conservation status and its further inclusion in lists of threatened plants have been evaluated in this work.

Since the late 19th century, different taxonomic views have been reported for Carpobrotus species occurring in the Maltese Islands, where the latest treatments imply two varieties of C. edulis and the doubtful occurrence of C. acinaciformis. Taxonomic inconsistencies are possibly derived from the poor understanding or misinterpretation of morphological characters. Moreover, the hybridogenous morphotypes resulting from horticultural advances make the determination of Carpobrotus even harder, especially with the application of outdated identification keys which do not take hybrids into account. The difficulty in determining Carpobrotus spp. has been expressed in several recent accounts within the Mediterranean region. A taxonomic investigation was carried out by applying eleven morphological characters adopted from recent monographs on 25 populations present in Malta. Three taxonomic units have been retrieved from the analyzed sample, where C. acinaciformis s.l. has been confirmed to represent all the purple-flowering populations and C. edulis s.s. for the yellow-flowering ones. Emphasis was given on the interpretation and understanding of distinctive morphological characters by employing a standardized method of assessment aided by images. This comparative morphological study resulted in a new characteristic in the leaves of C. edulis, by which it could be easily distinguished from C. acinaciformis in the vegetative state. A detailed discussion about the two different morphotypes of C. acinaciformis s.l. and dichotomous keys to distinguish Carpobrotus taxa are also provided.

Literature data and new records of members of the orchid family (Orchidaceae) in the Occupied Palestinian Territories were reviewed and updated with field data. Using data from the Palestine Museum of Natural History (PMNH), data from fellow botanists, and the Biodiversity databases (BioGIS and GBIF), the distribution patterns were analyzed with the QGIS package. Twenty-three taxa of eight genera were found in this preliminary study. For two species, no recent data from the last 20 years were available and in some cases likely declined due to human activity. Most species are from the Mediterranean phytogeographical zone, Epipactis veratrifolia Boiss. & Hohen was found in the Sudanian-Ethiopian zone (Dead Sea valley). The majority of the species found prefer semi-open shrublands (garrigue). Nine species had fewer than 20 records overall. Trends observed from the historical data, and current spatial data revealed major threats, including habitat fragmentation, urbanization, intensification of agricultural land use, afforestation and reduced precipitation due to global warming. We noted the proximity to thorny shrubs in many species indicating pressure by grazing animals during field visits. As recent data is scarce, surveys of sites where rare species have been encountered in the past are recommended, and measures to protect vulnerable populations are discussed.
