Abstract Aim Gymnosperms are often described as a marginal and threatened group, members of which tend to be out‐competed by angiosperms therefore preferentially persist at higher latitudes elevations. The aim our synthesis was test these statements investigating the global latitudinal elevational distribution gymnosperms, well their conservation status, using all extant gymnosperm groups (cycads, gnetophytes, ginkgophytes conifers). Location Worldwide. Methods We developed database 1014...
Trees are fundamental for Earth's biodiversity as primary producers and ecosystem engineers responsible many of nature's contributions to people. Yet, tree species at present threatened with extinction by human activities. Accurate identification is necessary quantify the current crisis prioritize conservation efforts. However, most comprehensive dataset risk-the Red List International Union Conservation Nature (IUCN RL)-lacks assessments a substantial number known species. The RL based on...
Understanding adaptive genetic variation and whether it can keep pace with predicted future climate change is critical in assessing the vulnerability of species developing conservation management strategies. The lack information on relict carrying abundant resources hinders assessment vulnerability. Using a landscape genomics approach, this study aimed to determine how shapes population divergence predict potential Pterocarya macroptera (a vulnerable China) under scenarios.We applied...
Abstract Aim The distribution range of Lactuca serriola , a species native to the summer‐dry mediterranean climate, has expanded northwards during last 250 years. This paper assesses influence climate on expansion this and highlights importance anthropogenic disturbance its spread. Location Central Northern Europe. Methods Data geographic L. were assembled through literature search as well floristic herbarium surveys. Maps spread in Europe prepared based data. was assessed more precisely...
Abstract Aim To establish a complete database of Juglandaceae at spatiotemporal scale and develop phylogeographic framework with which to elucidate the distributional patterns, diversity origins, evolution, conservation priority regions this family. Location Worldwide. Taxon Walnut family (Juglandaceae). Methods Data on distribution all extant fossil species were collected, followed by analyses its latitudinal distribution, elevational generic diversity. Furthermore, based genera 87%...
Brilliant colors in nature arise from the interference of light with periodic nanostructures resulting structural color. While such biological photonic structures have long attracted interest insects and plants, they are little known other groups organisms. Unexpected kingdom Amoebozoa, which assembles unicellular organisms, were observed myxomycetes, an evolutionary group amoebae forming macroscopic, fungal-like structures. Previous work related sparkling appearance Diachea leucopodia to...
ABSTRACT Aim Relict trees are the outcome of long‐term ‘natural experiments’. Accordingly, they provide opportunities to study effects local adaptation trees, which still poorly understood but crucial in context climate change. In turn, physical settings refugia at macro‐ and microscale key drivers environmental adaptability such species. Using two congeneric relict ( Zelkova sicula Z. abelicea ) as model species, we analysed functional relationships between tree growth patterns distinctive...
Abstract Relict species provide a unique opportunity to understand past and recent biogeographical evolutionary processes. Zelkova abelicea (Ulmaceae), which is endemic the island of Crete (Greece), one most prominent Tertiary relict trees Mediterranean region. We collected distribution, threat population structure data by reviewing literature herbaria through field surveys at 14 study plots throughout range species. The present distribution Z. extremely fragmented. Although total estimated...
Abstract Aim To elucidate the phylogeographical patterns in three Cenozoic relict species: Zelkova sicula , Z. abelicea and carpinifolia (Ulmaceae). Location Sicily, Crete Transcaucasia. Methods Two chloroplast loci ( trn H– psb A L) nuclear ribosomal markers ITS 1 2 were sequenced for 154 samples collected from 14 populations of 16 two known . We obtained georeferenced data, calculated median joining networks carried out diversity analyses. few ex situ botanical gardens, East Asian species...
Quercus litseoides, an endangered montane cloud forest species, is endemic to southern China. To understand the genomic features, phylogenetic relationships, and molecular evolution of Q. complete chloroplast (cp) genome was analyzed compared in section Cyclobalanopsis. The cp litseoides 160,782 bp length, with overall guanine cytosine (GC) content 36.9%. It contained 131 genes, including 86 protein-coding eight ribosomal RNA 37 transfer genes. A total 165 simple sequence repeats (SSRs) 48...
Environmental factors such as mountain tectonic movements and monsoons can enhance genetic differentiation by hindering inter- intraspecific gene flow. However, the phylogeographic breaks detected within species may differ depending on different molecular markers used, biological traits be a major confounding factor. <italic>Pterocarya hupehensis</italic> is vulnerable relict distributed throughout Sichuan Basin. Here, we investigated patterns evolutionary history of <italic>P. using...
Abstract Cliffs are remarkable environments that enable the existence of microclimates. These small, isolated sites, decoupled from regional macroclimate, play a significant role in maintaining species biodiversity, particularly topographically homogeneous landscapes. Our study investigated microclimate south‐exposed forests situated at edge sandstone cliffs western part North Alpine Foreland Basin Switzerland and its local forest community composition. Using direct measurements data...
Abstract Pterocarya fraxinifolia , native to the southern Caucasus and adjacent areas, has been widely introduced in Europe. In this study, we investigate following: (1) How did its current distribution form? (2) What are past, current, future suitable habitats of P. ? (3) is best conservation approach? Ecological niche modeling was applied determine climatic demands project climatically areas during three periods (2070) time. Then, an integrated analysis fossil data performed. Massive...
Relict species play an important role in understanding the biogeography of intercontinental disjunctions. Pterocarya (a relict genus) is valuable model taxon for studying East Asian versus southern European/West disjunct patterns. This disjunction has not been as well studied others (e.g., between Eastern Asia and North America). Several phylogenetic studies on have conducted, but none provided a satisfactory resolution. Here, we report first well-resolved phylogeny using restriction...
The elm family (Ulmaceae) is a woody plant group with important scientific, societal, and economic value. We aim to present the first biogeographic synthesis investigating global diversity, distribution, ecological preferences, conservation status of Ulmaceae. A literature review was performed explore available data for all extant species. Our study made it possible map actual distribution Ulmaceae high precision, elucidate centers located mainly in China southeastern USA. detailed...
Abstract Subtropical evergreen broad‐leaved forest (EBLF) is the predominant vegetation type in eastern China. However, majority of region it covers China was an arid area during Paleogene. The temporal history and essential factors involved evolution subtropical EBLFs remain enigmatic. Here we report on niche Quercus section Cyclobalanopsis , which appeared south Japan Eocene became a dominant component since Miocene Asia, using integrative analysis occurrences, climate data dated phylogeny...
