None of them has been explicitly typified to date. We studied materials from about twenty European herbaria, enabling us to locate and document the holotypes of seven of the names, as well as designate the lectotypes for 12 (a drawing in the case of Pedicularis lusitanica), a neotype for P. kerneri and an epitype for P. lusitanica. Other syntypes, isolectotypes and isoepitypes that could be located are also recorded in the list. Regarding the geographical origin, seven of the types were collected from the Pyrenees, such as those of the widespread P. pyrenaica and P. mixta, 10 from the rest of the Iberian Peninsula (three in Portugal and three in the Cantabrian range), and two from the Alps (those of P. allionii and P. kerneri, both also present in the Pyrenees). Finally, for the Cantabrian endemic plant first described as P. pyrenaica var. fallax, we propose the replacement name P. picoeuropeana.KEYWORDS: Nomenclatural typesOrobanchaceaePedicularisPyreneesIberian peninsulaAlps AcknowledgmentsWe are very grateful to the curators and technicians of the following herbaria for providing help and images of the requested specimens: B (Robert M.

The physicochemical characteristics of these springs (temperature, mineralization, gas content) result both from their deep circulation and from the geological formations or surface waters with which they interact during their ascent. In mineral springs, diatoms are well represented. To date, no study has focused on coupling the origin of water with diatom communities, whether in the Massif Central or in other parts of the world. The purpose of this study is to cross the information obtained on the water and the diatoms in order to analyse the biodiversity and improve knowledge of the species autecology. Twelve mineral springs with some of which have high levels of radioactivity were studied in the Massif Central. As results, the geochemical facies, the origin of the water and the Total Dissolved Solids influence the taxonomic composition but not the specific richness, Shannon index and Evenness. Furthermore, 222Rn influences diatom richness and community structure. Planothidium frequentissimum, Crenotia angustior and Sellaphora labernardierei were associated with high values of 222Rn activity. The water temperature was a factor that influences diatom species distribution. Some species appears to be more sensitive to the composition of water, such as Planothidium frequentissimum which attests to a mixing between deep and surface waters.KEYWORDS: Hydrochemistryradioecologydiatoms diversityautecologythermo-mineral springs AcknowledgmentsWe acknowledge financial support from CNRS-INEE within the context of the Zone Atelier Territoires Uranifères.

For this purpose, we examined the leaves of two evergreen species, i.e. Photinia × fraseri “Red Robin”, which has relatively small leaves, and Photinia serratifolia, which has relatively larger leaves. Approximately > 320 leaves from each species were collected monthly from April to August during the growing season, and the t-test was used to determine the significance of interspecific differences in lamina and petiole traits. Reduced major axis regression protocols were used to fit the scaling relationships of petiole fresh mass (PFM) vs. lamina fresh mass (LFM), PFM vs. lamina area (A), petiole dry mass (PDM) vs. lamina dry mass (LDM), and PDM vs. A. The increase in PDM was positively correlated with increasing LDM. However, there was a temporal variation in PDM/LDM. Both PDM/LDM and PFM/LFM for P. serratifolia were significantly higher than those of P. × fraseri. There was a strong positive correlation between petiole size (as measured by PFM and PDM) and lamina size (as measured by LFM, LDM and A). These relationships reveal statistically robust scaling relationships between petiole size and lamina size for each of the two species, and provide additional support for the hypothesis called “diminishing returns”, i.e. a disproportionate increase in one leaf trait (e.g. LDM) with respect to increasing another leaf trait (e.g. PDM).KEYWORDS: Lamina arealamina masspetiole massRosaceaescaling relationships AcknowledgmentsWe are deeply thankful to Prof. Karl J.

Despite three decades of research, analyses of species assemblage and functional traits are lacking. Leveraging a national monitoring network in metropolitan France, we aim to provide a comprehensive taxonomic and functional synthesis of field margin flora, outline main field margin types and explore their associations with management practices, climate, and agricultural landscapes. We analysed data from 532 field margins surveyed between 2013 and 2017, using both uni- and multivariate analyses. Field margins exhibited great diversity with 711 distinct taxa (12% of all flora in mainland France) at the national scale and an average of 16 species per 10 m2 locally. While field margins contained few species of conservation value, they offered a refuge for many declining species as well as rare arable weed species. We identified seven main field margin types, each linked to distinct conditions of climate, soil, landscape and agricultural practices. Mediterranean field margins notably differed from all others. In the main cluster, vineyard margins also stood out as distinct from annual crop margins. Additionally, field margins in landscapes with a high proportion of grassland differed from those within intensively cultivated field crop plains in conventional agriculture. Overall, our study highlights the high botanical diversity of field margins and their interest for plant conservation in agricultural landscapes. Promoting the installation and/or maintenance of field margins through agri-environmental schemes should thus favour biodiversity conservation and associated ecosystem provision.KEYWORDS: Field marginsvegetation typeagricultural practicesagroecosystemarable weedsfloraconservation valuetypology AcknowledgmentsThe 500 ENI network is developed by the French Ministry of Agriculture (DGAL) under the Ecophyto framework.

However, the genetic variability present in Brachypodium spp. continue being the aim of many research. Therefore, the aim of this work was to analyze the genetic variability present in different Brachypodium spp. from different countries and to find different open reading frames (ORFs) among them by using sequence-related amplified polymorphism (SRAP) markers. In our study, a total of 12 Brachypodium spp. accessions were selected from different countries. By using SRAP markers, the genetic variability was evaluated and some fragments were sequenced to obtain differential ORF information among genotypes. SRAP molecular markers revealed high variability among accessions being USA the accession that showed the most variability at the DNA level. The analysis of sequenced SRAP fragments from monomorphic and polymorphic fragments as well as those obtained from new primer combinations targeted coding regions into B. distachyon available genome. SRAP molecular marker showed not only to be an excellent tool for Brachypodium variability studies but also to provide additional information about differential amplification of open reading frames.","PeriodicalId":54302,"journal":{"name":"Botany Letters","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136192133","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}
