Many ecophysiological studies have dealt with the adaptation of plants to cope with these stresses in hot deserts, which are the territories that have better evoked the idea of a dryland. Nevertheless, drylands can also be found in some other areas of the Earth that are under the Mediterranean-type climates, which imposes a strong aridity during summer. In this review, plant species from hot deserts and Mediterranean-type climates serve as examples for describing and analyzing the different responses of trees and shrubs to aridity in drylands, with special emphasis on the structural and functional adaptations of plants to avoid the negative effects of high temperatures under drought conditions. -

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. -

The next morning early we met our large tour bus and its charming and skillful driver, Grigoris, who hails from the mountain village of Gardiki not far from here. We did a bit of leisurely botanizing before we reached Perdika, our first destination of the day. There are two reasons to visit Perdika: one is the Karavostasi beach, a curving strand with golden sand, and the archaeological site of Dymokastron, a Hellenis- tic mountain-top town reached by a steep hike. The view of the beach far below was beautiful, as it must have been when the town was still inhabited. The town was destroyed in 167 BCE by a Roman army, along with most of the other towns in the vicinity, all allied with Rome’s enemy, Macedonia. The site is under active excavation, and we were able to admire the remnants of protective walls (how in the world did they get those big stones up there?), building foundations, and cisterns, which were certainly needed in case of a prolonged siege, Some members of the IOS Greek tour relaxing under the plane tree in the which Dymocastron must have experienced more than once. village square.

Introduction. In the discovery of more potent and selective anticancer drugs, the research continually expands and explores new bioactive metabolites coming from diferent natural sources. Gallnuts are a group of very special natural products formed through parasitic interaction between plants and insects. Tough it has been traditionally used as a source of drugs for the treatment of cancerous diseases in traditional and folk medicinal systems through centuries, the anticancer properties of gallnuts are barely systematically reviewed. Objective. To evidence the traditional uses and phytochemicals and pharmacological mechanisms in anticancer aspects of gallnuts, a literature review was performed. Materials and Methods. Te systematic review approach consisted of searching web-based scientifc databases including PubMed, Web of Science, and Science Direct. -

Chamaerops Humilis Chamaerops Is a Genus of Flowering Plants in the Palm Family Arecaceae
Chamaerops humilis Chamaerops is a genus of flowering plants in the palm family Arecaceae. The only currently fully accepted species is Chamaerops humilis, variously called European fan palm or the Mediterranean dwarf palm. It is one of the most cold-hardy palms and is used in landscaping in temperate climates. Taxonomy Apart from the fully accepted Chamaerops humilis, there are a few taxa of unresolved status plus numerous species synonymised under Chamaerops humilis. The genus Chamaerops is closely related to the genus Trachycarpus. The genera differ in that Trachycarpus lacks the clumping habit only forms single stems without basal suckers), the spiny leaf stems (spineless in Trachycarpus), and in small details of the flower anatomy. Description Chamaerops humilis is a shrub-like clumping palm, with several stems growing from a single base. It has an underground rhizome which produces shoots with palmate, sclerophyllous leaves. The stems grow slowly and often tightly together, eventually reaching 2–5 m (10–20 ft) tall with a trunk diameter of 20–25 cm (8–10 in). The petioles are armed with numerous sharp, needle-like spines; these may protect the stem growing point from browsing animals. The flowers are borne in dense, short inflorescences at the tops of the stems. The plants usually, but not invariably, are dioecious with male and female flowers on separate plants. The number of flowers per inflorescence is highly variable for both male and female plants, depending on the size of the inflorescence. The seed (usually 0.6–0.8 g) contains a small cylindrical embryo, which is surrounded by several layers, from inner to outer as follows: a nutritious endosperm, a wide woody layer or endocarp, a fleshy and fibrous mesocarp (the pulp), and the thin outer layer or exocarp. -
The Wood Cross Sections of Hermann Nördlinger (1818–1897)
IAWA Journal, Vol. 29 (4), 2008: 439–457 THE WOOD CROSS SECTIONS OF HERMANN NÖRDLINGER (1818–1897) Ben Bubner Leibniz-Zentrum für Agrarlandschaftsforschung (ZALF) e.V., Institut für Landschaftsstoffdynamik, Eberswalder Str. 84, 15374 Müncheberg, Germany [E-mail: [email protected]] SUMMARY Hermann Nördlinger (1818–1897), forestry professor in Hohenheim, Germany, published a series of wood cross sections in the years 1852 to 1888 that are introduced here to the modern wood anatomist. The sec- tions, which vary from 50 to 100 μm in thickness, are mounted on sheets of paper and their quality is high enough to observe microscopic details. Their technical perfection is as remarkable as the mode of distribution: sections of 100 wood species were presented in a box together with a booklet containing wood anatomical descriptions. These boxes were dis- tributed as books by the publisher Cotta, from Stuttgart, Germany, with a maximum circulation of 500 per volume. Eleven volumes comprise 1100 wood species from all over the world. These include not only conifers and broadleaved trees but also shrubs, ferns and palms representing a wide variety of woody structures. Excerpts of this collection were also pub- lished in Russian, English and French. Today, volumes of Nördlingerʼs cross sections are found in libraries throughout Europe and the United States. Thus, they are relatively easily accessible to wood anatomists who are interested in historic wood sections. A checklist with the content of each volume is appended. Key words: Cross section, wood collection, wood anatomy, history. INTRODUCTION Wood scientists who want to distinguish wood species anatomically rely on thin sec- tions mounted on glass slides and descriptions in books that are illustrated with micro- photographs. -

The Scale Insects (Hemiptera: Coccoidea) of Oak Trees (Fagaceae: Quercus Spp.) in Israel
ISRAEL JOURNAL OF ENTOMOLOGY, Vol. 43, 2013, pp. 95-124 The scale insects (Hemiptera: Coccoidea) of oak trees (Fagaceae: Quercus spp.) in Israel MALKIE SPODEK1,2, YAIR BEN-DOV1 AND ZVI MENDEL1 1Department of Entomology, Volcani Center, Agricultural Research Organization, POB 6, Bet Dagan 50250, Israel 2Department of Entomology, Robert H. Smith Faculty of Agriculture, Food and Environment, The Hebrew University of Jerusalem, POB 12, Rehovot 76100, Israel Email: [email protected] ABSTRACT Scale insects (Hemiptera: Coccoidea) of four species of oaks (Fagaceae: Quercus) in Israel namely, Q. boissieri, Q. calliprinos, Q. ithaburensis, and Q. look were collected and identified from natural forest stands during the period 2010-2013. A total of twenty-seven species were determined from nine scale insect families: Asterolecaniidae (3 species), Coccidae (3), Di- aspididae (7), Eriococcidae (3), Kermesidae (6), Kuwaniidae (1), Mono- phlebidae (1), Pseudococcidae (2), and Putoidae (1). Six of these species represent new records for Israel and five are identified to the genus level. Kuwaniidae is a new family record for Israel. Species that were previously collected or recorded on oaks in Israel are listed and discussed. Information is given about host trees and global distribution. The majority of the spe- cies reported here are monophagous or stenophagous and they appear to be non-pestiferous to the oak trees in Israel. General traits that describe each scale insect family in the field are provided, together with an identification key to aid in the determination of slide-mounted specimens into families represented in this study. KEY WORDS: Scale insect, Coccoidea, oak trees, Quercus, forest, survey, monophagous, univoltine, Mediterranean, Israel INTRODUCTION The genus Quercus (Fagaceae) has a rich and diverse arthropod fauna associated with it (Southwood, 1961; Southwood et al., 2005). -
