  • What Is a Tree in the Mediterranean Basin Hotspot? a Critical Analysis
    Médail et al. Forest Ecosystems (2019) 6:17 https://doi.org/10.1186/s40663-019-0170-6 RESEARCH Open Access What is a tree in the Mediterranean Basin hotspot? A critical analysis Frédéric Médail1* , Anne-Christine Monnet1, Daniel Pavon1, Toni Nikolic2, Panayotis Dimopoulos3, Gianluigi Bacchetta4, Juan Arroyo5, Zoltán Barina6, Marwan Cheikh Albassatneh7, Gianniantonio Domina8, Bruno Fady9, Vlado Matevski10, Stephen Mifsud11 and Agathe Leriche1 Abstract Background: Tree species represent 20% of the vascular plant species worldwide and they play a crucial role in the global functioning of the biosphere. The Mediterranean Basin is one of the 36 world biodiversity hotspots, and it is estimated that forests covered 82% of the landscape before the first human impacts, thousands of years ago. However, the spatial distribution of the Mediterranean biodiversity is still imperfectly known, and a focus on tree species constitutes a key issue for understanding forest functioning and develop conservation strategies. Methods: We provide the first comprehensive checklist of all native tree taxa (species and subspecies) present in the Mediterranean-European region (from Portugal to Cyprus). We identified some cases of woody species difficult to categorize as trees that we further called “cryptic trees”. We collected the occurrences of tree taxa by “administrative regions”, i.e. country or large island, and by biogeographical provinces. We studied the species-area relationship, and evaluated the conservation issues for threatened taxa following IUCN criteria. Results: We identified 245 tree taxa that included 210 species and 35 subspecies, belonging to 33 families and 64 genera. It included 46 endemic tree taxa (30 species and 16 subspecies), mainly distributed within a single biogeographical unit.

  • Regional Patterns of Postglacial Changes in the Palearctic
    www.nature.com/scientificreports OPEN Regional patterns of postglacial changes in the Palearctic mammalian diversity indicate Received: 14 November 2014 Accepted: 06 July 2015 retreat to Siberian steppes rather Published: 06 August 2015 than extinction Věra Pavelková Řičánková, Jan Robovský, Jan Riegert & Jan Zrzavý We examined the presence of possible Recent refugia of Pleistocene mammalian faunas in Eurasia by analysing regional differences in the mammalian species composition, occurrence and extinction rates between Recent and Last Glacial faunas. Our analyses revealed that most of the widespread Last Glacial species have survived in the central Palearctic continental regions, most prominently in Altai–Sayan (followed by Kazakhstan and East European Plain). The Recent Altai–Sayan and Kazakhstan regions show species compositions very similar to their Pleistocene counterparts. The Palearctic regions have lost 12% of their mammalian species during the last 109,000 years. The major patterns of the postglacial changes in Palearctic mammalian diversity were not extinctions but rather radical shifts of species distribution ranges. Most of the Pleistocene mammalian fauna retreated eastwards, to the central Eurasian steppes, instead of northwards to the Arctic regions, considered Holocene refugia of Pleistocene megafauna. The central Eurasian Altai and Sayan mountains could thus be considered a present-day refugium of the Last Glacial biota, including mammals. Last Glacial landscape supported a unique mix of large species, now extinct or living in non-overlapping biomes, including rhino, bison, lion, reindeer, horse, muskox and mammoth1. The so called “mammoth steppe”2–4 community thrived for approximately 100,000 years without major changes, and then became extinct by the end of Pleistocene, around 12,000 years BP5,6.

It is assumed that similarities among communities from similar environments in different realms are the result of convergence, whereas their differences are interpreted as being due to different historical processes. Location Holarctic realm, North America and Eurasia above 25° N. Methods Checklists of mammalian species occurring in 96 Holarctic localities were collected from published sources. Species were assigned to one of 20 functional groups defined by diet, body size and three-dimensional use of space. The matrix composed of the frequencies of functional groups in the 96 localities is used as input data in a correspondence analysis (CA). The localities are classified into nine groups according to Bailey’s ecoregions (used as a surrogate of regional climate), and the positions of the communities in the dimensions of the CA are compared in relation to ecoregion and realm. Partial regression was used to test for the relative influence of ecoregion and realm over each dimension and to evaluate the effect of biogeographical realm on the variation in the factor scores of the communities of the same ecoregion.

  • Extinction of Threatened Vertebrates Will Lead to Idiosyncratic Changes in Functional Diversity Across the World ✉ Aurele Toussaint 1 , Sébastien Brosse 2, C
    ARTICLE https://doi.org/10.1038/s41467-021-25293-0 OPEN Extinction of threatened vertebrates will lead to idiosyncratic changes in functional diversity across the world ✉ Aurele Toussaint 1 , Sébastien Brosse 2, C. Guillermo Bueno1, Meelis Pärtel 1, Riin Tamme 1 & Carlos P. Carmona 1 1234567890():,; Although species with larger body size and slow pace of life have a higher risk of extinction at a global scale, it is unclear whether this global trend will be consistent across biogeographic realms. Here we measure the functional diversity of terrestrial and freshwater vertebrates in the six terrestrial biogeographic realms and predict their future changes through scenarios mimicking a gradient of extinction risk of threatened species. We show vastly different effects of extinctions on functional diversity between taxonomic groups and realms, ranging from almost no decline to deep functional losses. The Indo-Malay and Palearctic realms are par- ticularly inclined to experience a drastic loss of functional diversity reaching 29 and 31%, respectively. Birds, mammals, and reptiles regionally display a consistent functional diversity loss, while the projected losses of amphibians and freshwater fishes differ across realms. More efficient global conservation policies should consider marked regional losses of func- tional diversity across the world. 1 Institute of Ecology and Earth Sciences, University of Tartu, Tartu, Estonia. 2 Université Paul Sabatier, CNRS, IRD, UMR5174 EDB (Laboratoire Évolution et ✉ Diversité Biologique), Toulouse, France. email: [email protected] NATURE COMMUNICATIONS | (2021) 12:5162 | https://doi.org/10.1038/s41467-021-25293-0 | www.nature.com/naturecommunications 1 ARTICLE NATURE COMMUNICATIONS | https://doi.org/10.1038/s41467-021-25293-0 he loss of global biodiversity is accelerating throughout the with different key aspects of their ecology and their life-history Tworld1 triggering the sixth mass extinction crisis2.

Reptile species Received: 14/01/2018 were identified from collections made during field studies or recorded in literature, with some Accepted: 18/06/2018 new locality records obtained. Field studies were undertaken over two consecutive years (2016 and 2017). Two lacertid species, one skink species, two colubrid species and one viper species were officially recorded for the first time or their information was updated. In addition to Keywords species locality records, chorotypical and habitat selection were also assessed and the Viper International Union for Conservation of Nature Red List of Threatened Species criteria Reptilia included. Data on the distribution and locality information for each taxon is also provided. Our Fauna findings demonstrate that Amasya might be an ecotone zone between the Mediterranean, Chorotype Caucasian, and European ecosystems. Although there are some concerns for the sustainable Eunis dynamics of reptilian fauna, relatively rich and different European nature information system habitat types provide basic survival conditions for reptilian fauna in the province. 1.
