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. -

Effect of Earthworms on Mycorrhization, Root Morphology
www.nature.com/scientificreports OPEN Efect of earthworms on mycorrhization, root morphology and biomass of silver fr seedlings inoculated with black summer trufe (Tuber aestivum Vittad.) Tina Unuk Nahberger 1, Gian Maria Niccolò Benucci 2, Hojka Kraigher 1 & Tine Grebenc 1* Species of the genus Tuber have gained a lot of attention in recent decades due to their aromatic hypogenous fruitbodies, which can bring high prices on the market. The tendency in trufe production is to infect oak, hazel, beech, etc. in greenhouse conditions. We aimed to show whether silver fr (Abies alba Mill.) can be an appropriate host partner for commercial mycorrhization with trufes, and how earthworms in the inoculation substrate would afect the mycorrhization dynamics. Silver fr seedlings inoculated with Tuber. aestivum were analyzed for root system parameters and mycorrhization, how earthworms afect the bare root system, and if mycorrhization parameters change when earthworms are added to the inoculation substrate. Seedlings were analyzed 6 and 12 months after spore inoculation. Mycorrhization with or without earthworms revealed contrasting efects on fne root biomass and morphology of silver fr seedlings. Only a few of the assessed fne root parameters showed statistically signifcant response, namely higher fne root biomass and fne root tip density in inoculated seedlings without earthworms 6 months after inoculation, lower fne root tip density when earthworms were added, the specifc root tip density increased in inoculated seedlings without earthworms 12 months after inoculation, and general negative efect of earthworm on branching density. Silver fr was confrmed as a suitable host partner for commercial mycorrhization with trufes, with 6% and 35% mycorrhization 6 months after inoculation and between 36% and 55% mycorrhization 12 months after inoculation. -

Rapid MALDI-TOF MS Identification of Commercial Truffles
www.nature.com/scientificreports OPEN Rapid MALDI-TOF MS identifcation of commercial trufes Khalid El Karkouri1,2*, Carine Couderc1,3, Philippe Decloquement1,3, Annick Abeille1,3 & Didier Raoult1,3* Trufes are edible mushrooms with similar morphological characteristics, that make it difcult to distinguish between highly prized trufes (such as the Périgord black T. melanosporum) and inexpensive trufes (such as the Asian Black T. indicum). These biological and economic features have led to several misidentifcations and/or fraudulent proft in the trufe markets. In this paper, we investigate Matrix- assisted Laser Desorption/Ionization Time-Of-Flight Mass Spectrometry (MALDI-TOF MS) biotyping to identify 34 commercial fresh trufes from Europe and Asia. The MALDI-TOF MS clustering rapidly distinguished seven Tuber species identifed by ITS phylogenetic analysis. The tasty T. melanosporum was clearly diferentiated from the Chinese and less expensive trufes. These cheaper mushrooms were marketed as T. indicum but corresponded to a mix of three species. In total, the method confrmed misidentifcations in 26% of commercial specimens. Several unknown blind-coded trufes were rapidly identifed, with scores >= 2, using the Bruker Biotyper algorithm against MS databases. This study demonstrates that MALDI-TOF MS is a reliable, rapid and cheaper new tool compared with molecular methods for the identifcation of trufe species and could be used to control frauds in the trufe markets. It could also be useful for the certifcation of trufe-inoculated seedlings and/or diversity in forest ecosystems. Trufes are Ascomycetes belonging to the genus Tuber F. H. Wigg. (order: Tuberacaea, family: Pezizales). Tese edible mushrooms are hypogenous and form ectomycorrhizae, a mutualistic symbiosis with the ascocarps (i.e. -
Determining Mycorrhiza Rate in Some Oak Species Inoculated with Tuber Aestivum Vittad
Turkish Journal of Forestry | Türkiye Ormancılık Dergisi 2018, 19(3): 226-232 | Research article (Araştırma makalesi) Determining mycorrhiza rate in some oak species inoculated with Tuber aestivum Vittad. (summer truffle) Sevgin Özderina,*, Ferah Yılmazb, Hakan Allıc Abstract: Truffle cultivation is important because it has contributions to tourism as well as other sectors and is a significant activity especially in stimulating rural economy. In this article, it is aimed to determine the most suitable oak species for the development of the Tuber aestivum Vittad. (summer truffle) and to provide guidance for the establishment of truffle gardens. Quercus robur L., Q. ilex L., Q. coccifera L were germinated, the seedlings were inoculated with T. aestivum which is an important element of Turkish biological diversity. The mycorrhiza were counted in the roots after the 15-month growth period of the seedlings to which T. aestivum was inoculated. As a result of the counts, it was determined that the rate of the roots with mycorrhiza (PT) was 0.93 in Q. robur L., 0.91 in Q. coccifera L. and 0.90 in Q. ilex L. Contaminated root rate (PC) was 0.28 in Q. robur L., 0.28 in Q. ilex L. and 0.30 in Q. coccifera L. According to the results, Q. robur is the oak species with the highest mycorrhizal development rate. Keywords: Tuber aestivum, Truffle, Oak, Muğla, Turkey Tuber aestivum Vittad.

COST Action FP 0703 – ECHOES DRAFT Country Report CYPRUS
DRAFT COUNTRY REPORT - CYPRUS COST action FP 0703 – ECHOES Expected Climate Change and Options for European Silviculture DRAFT Country Report CYPRUS Forestry Department Ministry of Agriculture, Natural Resources and Environment Cyprus July 2009 1 DRAFT COUNTRY REPORT - CYPRUS INTRODUCTION The aim of this report is to present the situation of climate change and forestry in Cyprus. Furthermore it could be used as a source of facts and ideas regarding climate change and the overall situation in a typical Mediterranean country. Cyprus is the third largest island of the Mediterranean with a total area of 9.251 km 2 and is situated at the north-eastern end of the Mediterranean basin. The longitude of Cyprus is 33°20’’ east and the latitude is 35°12’’ north. In relation to its size, Cyprus has one of the richest floras in the Mediterranean region (a total of 1907 taxa were recorded from which the 7% are endemic to the island). This is due to a number of factors, including its geographic location (situated at the boundary of tree continents), its insular character, the surrounding sea and the topographical configuration. Extensive plains, mountain masses, wetlands, coasts, sand dunes, gorges and cliffs provide a home for many indigenous and endemic species. Geomorphologically, Cyprus lies in a mountainous terrain composed by two mountain ranges, the Troodos and Pendadactylos and the alluvial plains of Mesaoria between the two ranges. The highest peak is Olympus at the Troodos Range with an altitude of 1952 m. An 18,55% of the island is covered by forests which are very important because of their direct and indirect use values. -

Oaks for the Adelaide Plains: Successful Species in the Waite Arboretum
Treenet Proceedings of the 4 th National Street Tree Symposium: 4 th and 5 th September 2003 ISBN 0-9775084-3-9 Treenet Inc OAKS FOR THE ADELAIDE PLAINS: SUCCESSFUL SPECIES IN THE WAITE ARBORETUM Jennifer Gardner , Waite Arboretum, University of Adelaide, South Australia Abstract The University of Adelaide’s Waite Arboretum is a valuable experimental collection. Species of oaks performing well there under natural rainfall of 625 mm are reported. Most successful are the species from the Mediterranean region, California and Mexico. Many of these oaks have potential for street or amenity planting. Introduction Oaks belong to Quercus, one of eight genera in the family Fagaceae that occurs primarily in temperate Northern Hemisphere. The family also includes sweet chestnuts Castanea (8 spp.), Trigonobalanus (3 spp.), beeches Fagus (10 spp.), Chrysolepis (2 spp.) and two tropical genera Castanopsis (134 spp.) and Lithocarpus (325 spp.) (Govaerts & Frodin, 1998). In Australia the family is represented by the Gondwanan genus Nothofagus (34 spp.) which considered to be in a separate family by Hill & Jordan (1993). Of the 531 species of oaks, about 250 occur in the Americas, 125 in Asia and Malesia and the rest in Europe, N. Africa and Macaronesia (Govaerts & Frodin, 1998). Sierra Madre Occidental, Mexico and East and Southeastern Asia are rich in species. The infrageneric taxonomy of oaks is in a state of flux and various schemes exist. Oaks are widely cultivated, and widespread hybridisation and high variability make the delimitation of some species contentious. The Waite Arboretum The Waite Arboretum is nestled in the foothills of Adelaide, South Australia , 34 o58’S 138 o 38’E at an altitude of 100 – 110m.
