Abstract The European Alps are highly rich in species, but their future may be threatened by ongoing changes human land use and climate. Here, we reconstructed vegetation, temperature, impact livestock over the past ~12,000 years from Lake Sulsseewli, based on sedimentary ancient plant mammal DNA, pollen, spores, chironomids, microcharcoal. We assembled a highly-complete local DNA reference library (PhyloAlps, 3923 taxa), used this to obtain an exceptionally sed aDNA record of 366 taxa....
Abstract There is still limited consensus on the evolutionary history of species-rich temperate alpine floras due to a lack comparable and high-quality phylogenetic data covering multiple plant lineages. Here we reconstructed when how European lineages diversified, i.e., tempo drivers speciation events. We performed full-plastome phylogenomics used multi-clade comparative models applied six representative angiosperm that have diversified in mountains (212 sampled species, 251 ingroup species...
Until recently, Passiflora cerasina was known only from two herbarium specimens. Three botanical expeditions in French Guiana, 2008, 2009, and 2017, have greatly improved our knowledge on its geographical distribution morphological variation. A key to the Guianese species of series Laurifoliae is given. As holotype mentioned original description missing, we propose a neotype collected locus classicus.
<title>Abstract</title> We present a decade-long research initiative of biodiversity genomics, which aimed at sequencing all vascular plant species occurring in the hotspot European Alps, along with related lineages other mountain ranges and arctic region. detail sampling strategies, an online database for genome skimming datasets, bioinformatic procedures to retrieve sequence data. Based on low coverage shotgun 6,105 species, we generated dataset 81 orthologous chloroplast loci, including...
While soil ecosystems undergo important modifications due to global change, the effect of properties on plant distributions is still poorly understood. Plant growth not only controlled by physico‐chemistry but also microbial activities through decomposition organic matter and recycling nutrients essential for plants. A growing body evidence suggests that functional traits modulate species’ response environmental gradients. However, no study has yet contrasted importance physico‐chemistry,...
Low-coverage whole genome shotgun sequencing (or skimming) has emerged as a cost-effective method for acquiring genomic data in nonmodel organisms. This provides sequence information on chloroplast (cpDNA), mitochondrial (mtDNA) and nuclear ribosomal regions (rDNA), which are over-represented within cells. However, numerous bioinformatic challenges remain to accurately rapidly obtain such organisms with complex structures rearrangements, particular mtDNA plants or cpDNA some plant families....
Recent climate and land use change, pollution have led to concerning alterations in biodiversity ecosystem functions, jeopardizing nature's contributions people. Mountainous regions are not immune these threats, experiencing the impacts of global warming, increased recreational activities, changes agricultural practices. Leveraging natural elevational gradients mountain environments, ORCHAMP program was established 2016 as a comprehensive initiative monitor, understand, predict repercussions...
Ranunculaceae comprise ca. 2,500 species (ca. 55 genera) that display a broad range of floral diversity, particularly at the level perianth. Petals, when present, are often referred to as "elaborate" because they have complex morphology. In addition, petals usually produce and store nectar, which gives them crucial functional role in interaction with pollinators. Its morphological diversity richness make this family suitable model group for studying evolution morphologies. Our aims (1)...
Within the huge diversity of genus Passiflora, series Laurifoliae constitutes a strikingly uniform group, widely distributed in neotropical rain forests, at low to moderate elevations. Given its morphological and ecological unity, Killip mentionned it as an «exceedingly difficult» group. The lack clear criteria has not helped delimiting it, confusion grown with addition new species criteria. As preliminary step study within Laurifoliae, we re-examine delimitation, assessing how current 29...
Passiflorariparia was incompletely described by Masters, who cited specimens of Martius and Spruce. While Spruce 2191, the unique syntype with an observable corona, exhibits a reduced outermost series filaments, accompanying iconography represents two equal outer series. Later descriptions have neither added significant information nor corrected inconsistency in corona description, so that four closely related species been distinguished on basis traits not properly documented for P.riparia:...
Helianthemum nummularium is a European shrub growing at high altitude where it copes with level of stress. It was found to be overexpressed in ungulates diets compared more abundant surrounding plants. These elements combined the fact that H. from Alps has never been investigated prompted us study phytochemical composition its aerial parts. The analysis polar extract allowed for isolation eight compounds: p-hydroxybenzoic acid, tiliroside, kaempferol, astragalin, quercetin, plantainoside B,...
Passiflora kapiriensis is a new Guianese species in the series Laurifoliae of subgenus Passiflora, found near Saint-Georges-de-l'Oyapock.The filaments fourth corona row are 1 cm long and oriented to androgynophore, which reminiscent P. acuminata, cerasina, fissurosa, killipiana nitida.It differs from these close relatives by combination subequal first second rows filaments, very short hypanthium, petioles, with medial nectary glands, much larger leaves.
Passiflora tinifolia Juss. (Passiflora sousgenre Passiflora): résurrection et synonymies. Dans la série Laurifoliae du sous-genre Passiflora, le nom laurifolia L. possède quatre synonymes: P. oblongifolia Pulle, décrite Suriname connue seulement type, de l'île Cayenne, var. tinifolia, considérée comme variété à petits fruits ou Granadilla laurifolia. Plus récemment, gabrielleana Vanderpl. favardensis Kuethe ont été décrites Guyane Française partagent nombreux traits avec ces taxons. Quatre...
Une checklist révisée et annotée du genre Passiflora L. en Guyane Française. La présente révision (Passifloraceae Juss. ex Roussel) met à jour la liste guyanaise de 2014 avec des données collecte récentes avancées taxonomiques nomenclaturales concernant française. Elle répertorie 44 taxons passiflores, dont 27 appartenant au sous-genre L., six Decaloba (DC.) Rchb., un taxon Deidamioides (Harms) Killip, dix Astrophea(DC.) Mast. Sept noms d'espèces sont typifiés d'autres annotées comme...
Within the very uniform series Laurifoliae, Passifloraacuminata (treated as a synonym of P.laurifolia in Flora China), P.tolimana, P.gleasonii and P.metae appear particularly similar. A review their descriptions associated specimens confirms lack morphological differentiation leads us to formally resurrect P.acuminata place three other taxa under its synonymy. This taxonomic move is also supported by revision 72 additional geolocalized (for grand total 78) an analysis distribution habitats....
From the "Description des plantes d'Amérique" by Plumier, in 1693, to "Species Plantarum" Linnaeus 1753, several dubious synonymies of Passiflora laurifolia L. were proposed, generating a persisting confusion. A revision process, which led Linnaean description this species, shows that type finally chosen Cusset does not match original description. new lectotype for species and more complete are proposed from field observations, herbarium bibliographic data.
Taxonomy and evolution in Passiflora : a synthesis of current knowledge. L. is the most important genus family Passifloraceae, native to tropical America, South-East Asia Oceania. Mainly distributed neotropics, from coastal regions elevations about 4,300 m, its 576 species have adapted highly diverse environments forged many strong interactions with animals (herbivory, mutualisms pollination protection), giving rise formidable diversity through particularly complex phylogeography. Since...
