Its populations are located in France and North Africa, being absent in the Iberian Peninsula.. It was described by Delile, but its taxonomic and nomenclatural status has been discussed by several authors, mainly based on its particular combination of morphological characters. We have recently found several populations of a Cistus species whose morphological characters match those of C. pouzolzii. To confirm the taxonomic identity of these populations, a comparative study was performed using herbarium specimens of C. pouzolzii from France and North Africa. In addition, two chloroplast regions were sequenced to study the phylogenetic relationships between the newly discovered Iberian populations and the rest of the species of the genus Cistus, including the sequences belonging to C. pouzolzii from France and Morocco previously used. Both analyses (morphological and phylogenetic studies) confirmed that the specimens sampled in the Iberian populations were C. pouzolzii. Furthermore, both the nomenclature of this species and its conservation status are briefly discussed.","PeriodicalId":54240,"journal":{"name":"Mediterranean Botany","volume":"23 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2023-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139230268","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Codonoprasum represents an evolutionarily young and rapidly radiating group of bulbous geophytes, with a significant proportion of polyploids and minor morphological differences between species. In the last 20 years, dozens of new species of this section have been described from the Mediterranean. Still, very little new information has been obtained on most of them since their description, especially concerning cytogenetic, molecular, and distribution data. Allium goumenissanum is a recently described species of this section, known only from three nearby localities in northern Greece. During the last 10 years, the senior authors' team collected population samples of an unknown species of this section from the southern Balkans, which appeared to be representative of A. goumenissanum. Using an integrated approach employing a range of methods (cytogenic, molecular, morpho- and micromorphological methods), the populations of an unknown species were compared with morphologically similar species A. goumenissanum and A. stamatiadae. AFLP, ITS sequencing and genome size analyses revealed that all the populations of the unknown species represent A. goumenissanum, and that this species is differentiated genetically and in genome size from A. stamatiadae. ITS sequencing indicates an allotriploid origin of A. goumenissanum from unknown ancestors. The characterization of the morphology and reproduction of A. goumenissanum is completed and micromorphological and anatomical characteristics of the leaves of both species are newly published. The distribution of A. goumenissanum, based on new data, now includes a more extensive area of north central Greece and the species has been found as a new one for Bulgaria.","PeriodicalId":54240,"journal":{"name":"Mediterranean Botany","volume":"26 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2023-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139230431","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In dichogamous flowers—in which female and male functions are decoupled in time—the duration of the female phase is expected to vary according to pollination status. We used Aristolochia rotunda as a model to test the hypothesis that the female phase should be shortened following pollen deposition on the stigma, and to identify the signal for phase switching. Aristolochia flowers are protogynous (female phase first) and trap pollinators for several days (trap flowers). The four experimental treatments we applied to flowers, i.e. hand pollination, presence of pollinators with or without pollen load in the flower, and deposition of a nylon thread on the stigma, shortened the female phase to a similar extent, demonstrating that the duration of the female phase depended on the presence of pollinators, independently of whether or not they carried pollen, and that mechanical stimulation of the stigmas was the signal for phase switching. Temperature was also shown to shorten the female stage. This mechanism of post-anthesis floral changes is original because usually such changes are triggered by chemical interactions between pollen and stigmas. We interpret the mechanical signal used in A. rotunda for phase switching to be adaptive when pollinators are limiting, because switching to the male phase even if the trapped pollinator does not bring pollen would ensure fulfilling the flower’s male function.","PeriodicalId":54240,"journal":{"name":"Mediterranean Botany","volume":"281 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135618925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These clays tend to give rise to a specific type of soil, known as \"vertisols\" or related argillic soils with vertic behaviour, varied chemical and sedimentological composition, and occasionally siliceous or dolomitic clasts. In these soils, where there is an absence of woody vegetation, the colonising nitrophilous vegetation becomes of particular interest through the usage and alteration of the land. These argillic soil plant communities are incredibly diversified, with flora suited to the unique hydrogeochemical conditions of these settings. The variety of these plant communities is determined by factors such as land use, lithology, terrain, and the level of humidity they can withstand. We identify the primary plant community on the Madrid-Toledo expansive clays in this paper, as well as provide a preliminary approach to the different varieties and transitions to other related plant communities. The main dynamic and catena links are established, and a floristically summarised table is provided, along with a descriptive examination of the community's behaviour and variability. Finally, its conservation status and the high degree of threat to which it is subjected are assessed.","PeriodicalId":54240,"journal":{"name":"Mediterranean Botany","volume":"281 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135619339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the methodology of the Bioclimatic Classification of Earth was applied. Twelve Temperature and Precipitation climatic parameters were used and three bioclimatic indices corresponding to 54 Bioclimatic Reference Localities (BRL) established in the study area were also calculated. From them we determined the bioclimatic units of each BRL at the level of Macrobioclimate, Bioclimate, Thermotypes and Ombrotypes. Subsequently, three bioclimatic maps (Bioclimate, Thermotypes and Ombrotypes) and two bioclimatic distribution maps of the forests and its vegetation belt (Premontane Forest and Montane Rainforest) were digitally developed using the QGIS software. The results obtained show that these forests are distributed within the Tropical Macrobioclimate and Tropical Pluviseasonal Bioclimate, with Upper Thermotropical and Lower Mesotropical thermotypes and Lower Subhumid and Upper Subhumid ombrotypes. The lowest vegetation belt, the Premontane Forest, is distributed between (≈400) 429-889 (≈900) m asl and exhibits two thermal variants: the warm Thermotropical Premontane Forest and the more temperate Mesotropical Premontane Forest. The Montane Rainforest is distributed at higher altitudes between (≈900) 965-1178 (≈1200) m als under Lower Mesotropical Thermotype. Both vegetation belts present two ombric variants, whose geographic distribution is determined by the precipitation gradient operating in the region: towards the West, the more humid variants are distributed under the Upper Subhumid ombrotype, while towards the East, the less humid variants are found under Lower Subhumid ombrotype. The present work constitutes the first bioclimatic study carried out in this forest formation applying the methodology of the Bioclimatic Classification of the Earth. It also lays the foundations and contributes whith valuable information to future floristic, vegetational, ecological and biogeographical studies and those focused on the conservation and sustainable management of native forests at the northern extreme of Argentina.","PeriodicalId":54240,"journal":{"name":"Mediterranean Botany","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135618765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
