Rhododendron myrtifolium and R. ferrugineum are small, shrubby plant species that are morphologically similar to each other. They both grow on siliceous substrates in the subalpine belt of European mountains. In the present study, leaves and capsules from 11 populations of R. myrtifolium from the Carpathians were compared with those from 13 populat...
The genus Zelkova (Ulmaceae) has occurred in Europe and Southwest Asia since the Eocene represented mostly by the fossil-species Z. zelkovifolia. Currently, relict populations of Z. abelicea, Z. sicula and Z. carpinifolia can be found in Crete, Sicily and the Euxino-Hyrcanian province, respectively. To reveal relationships between extinct and extan...
Pterocarya fraxinifolia, native to the southern Caucasus and adjacent areas, has been widely introduced in Europe. In this study, we investigate the following: (1) How did its current distribution form? (2) What are the past, current, and future suitable habitats of P. fraxinifolia? (3) What is the best conservation approach? Ecological niche model...
The commonly observed negative relationship between stomatal density (SD) and atmospheric CO2 has led to SD being proposed as an indicator of atmospheric CO2 concentration. The use of SD as a proxy for CO2, however, has been hampered by an insufficient understanding of intraspecific variation of this trait. We hypothesized that SD in Pinus sylvestr...
Vietnam is one of the main centers of generic diversity for Juglandaceae worldwide. In this study, we present for the first time a province-wide distribution of all 3 subfamilies, 7 genera, and 11 Vietnamese species, and give an update on the habitats of all Vietnamese Juglandaceae species, their uses, and current threats. Juglandaceae are found th...
Key message:
No evidence of coordination between leaf hydraulic function and stomatal characteristics was observed in young hybrid aspen stands attributable to the near-anisohydric behaviour and the fast-growing nature of this species.
Abstract:
Within forest canopies, there are environmental gradients that enhance water losses in the direction o...
Pinus syvestris from the Iberian Peninsula was biometrically compared, using needle morphological and anatomical characteristics from 15, and cone morphological characteristics from nine natural populations. Samples of Scots pine represent subspecies nevadensis and varieties pyrenaica, catalaunica, and iberica. Analyses included 25 needle and 17 co...
The relict tree species Zelkova abelicea and Z. sicula (Ulmaceae) occur in Crete and Sicily, respectively. Zelkova abelicea grows in approximately 40 localities in the mountains of Crete, while Z. sicula has been found in only two stands in Sicily. We compared 25 morphological characters of the leaves of both species and used statistical methods (T...
The firs (genus Abies, Pinaceae) species are a diverse and ecologically and economically important forest trees. In the Mediterranean and Central Europe, the genus Abies comprises twelve taxa with only partially resolved systematic statuses, and it has been classically divided into the sections Piceaster (fir-type 'ancestral' group) and Abies (fir-...
Scots pine (Pinus sylvestris L.) and the taxa from the P. mugo complex can hybridize in the contact zones and produce fertile hybrids. A unique example of an early Holocene relict population of P. sylvestris and P. uliginosa (a taxon from the P. mugo complex) growing on the tops of Jurassic sandstone rocks is located in Błędne Skały (Sudetes). Phen...

This symposium in Shanghai is to provide a platform for sharing...
Juniperus drupacea is a unique relict species found in the mountains of southern Greece, southern Turkey, and western Syria and Lebanon. The aim of this study was to describe the natural range of this juniper by determining the current locations of its populations and to predict a theoretical range for the species based on current, past, and future...
Riparian trees, especially relict trees, are attractive and important for research to understand both past and recent biogeographical and evolutionary processes. Our work is the first study to elucidate the genetic diversity and spatial genetic structure of the canopy-dominating riparian Pterocarya fraxinifolia (Juglandaceae) along two altitudinal...
Relict tree genus Zelkova: short presentation
Zelkova is a small genus of relict trees belonging to the elm family (Ulmaceae). Species of Zelkova were important elements of the vast forests that prevailed throughout the Northern Hemisphere during much of the Cenozoic Era. The oldest fossils that are attributed to Zelkova date from the early Eocene...
We used 39 morphological and anatomical needle traits in the biometric comparisons Abies nebrodensis with A. alba and A. cephalonica. The multivariate analyses were utilised and a closer relationship of A. nebrodensis to A. cephalonica than to A. alba was detected, in contrast to what has been shown for cone characteristics.
The needles from 25 trees of Abies equi-trojani from the Kazdağ (Mt. Ida) were compared with those from four populations of A. alba, two of A. cephalonica, and from three of each of A. ×borisii-regis, A. bornmuelleriana and A. nordmanniana, each represented by 29–31 individuals. Thirty-nine morphological and anatomical needle characters were examin...
Juniperus drupacea is an eastern Mediterranean mountain tree with a disjunct geographical range. We hypothesized that this disjunct occurrence (the Peloponnese in Europe and the Taurus and Lebanon Mountains in Asia) should be reflected in the patterns of genetic and morphological diversity and differentiation. Nuclear microsatellite markers (nSSR)...
Three populations of Abies cilicica subsp. isaurica and four of A. cilicica subsp. cilicica were analyzed using 35 morphological and anatomical needle characters with the implementation of multivariate statistical methods to verify the differences between subspecies. Moreover, the possible geographic differentiation of A. cilicica subsp. cilicica p...
Zelkova carpinifolia is a relict tree occurring in refugial zones of south-western Eurasia. The main aim of the study was the biometrical comparison of the leaf characteristics of the species sampled in three regions of Transcaucasia. We aimed to test the hypotheses that (1) leaves from vegetative (L) shoots would be larger and more variable than t...
The phenotypic differentiation of Pinus mugo complex was verified using 31 populations of P. mugo sensu stricto, 11 of P. uncinata, five of P. uliginosa, one of the potential hybrids P. uliginosa × P. mugo and three of P. sylvestris, the latter as a control. The 22 morphological and anatomical needle characteristics were measured and statistically...
This study was performed on hybrid aspen saplings growing at the Free Air Humidity Manipulation site in Estonia. We investigated changes in wood anatomy and hydraulic conductivity in response to increased air humidity. Two hydraulic traits (specific conductivity and leaf-specific conductivity) and four anatomical traits of stem wood – relative vess...
The study investigated the effects of exposure to increased relative air humidity (RH) on stomatal morphology and sensitivity to stomata closure inducing stimulus (low RH) in hybrid aspen (Populus tremula L. × P. tremuloides Michx.) coppice growing in field conditions. Artificially elevated RH reduced air vapour pressure deficit by 5%–10% and alter...
Zelkova carpinifolia is a relict tree of the elm family (Ulmaceae) that is endemic to the Transcaucasian area, which is considered to be one of the most important refugial zones of the relict flora in south-western Eurasia. The main aim of the study was the biometrical comparison of the leaf material of Z. carpinifolia that was sampled in selected...
We studied the physicochemical properties of stemwood in saplings of silver birch (Betula pendula Roth) and hybrid aspen (Populus tremula L. × P. tremuloides Michx.), grown for four years under artificially elevated relative air humidity (on average by 7%) in field conditions, using the Free Air Humidity Manipulation (FAHM) research facility in Est...
Divergence in genetic as well as phenotypic structures can be expected in species with disjunctive geographic ranges and restricted gene flow among isolated populations. Dwarf mountain pine has such a disjunctive geographic range in the mountains of Central Europe. We hypothesised that populations of Pinus mugo from the Giant Mts. differ from Alpin...
The phenotypic differentiation of relic P. sylvestris in southern Europe and southwestern Asia was verified using thirty-two populations sampled from the Iberian Peninsula, Massif Central, Balkan Peninsula, Crimea and Anatolia. Twenty-one morphological and anatomical needle traits and 18 cone morphological characteristics were examined to describe...
Despite Juniperus spp. being an important component of Mediterranean arid and semi-arid ecosystems, there is a lack of complex studies on their biogeographical patterns. Using 16 morphological cone and seed traits and three nuclear microsatellite markers, we investigated the morphological and genetic variability of seven Mediterranean and Macarones...
The aim of this study was the biometrical comparison of Abies pinsapo Boiss., Abies maroccana Trab. and Abies tazaotana Côzar ex Villar from Spain and Morocco. The morphological and anatomical analysis of the needle characters of these firs revealed significant taxonomic differences. The results showed considerable distances between regions and ver...
Juniperus thurifera is an important component of woodland communities of dry sites within the West Mediterranean region and is characterised by a strongly disjunctive geographic range. Two subspecies were recognised, subsp. thurifera in Europe and subsp. africana in Africa. The aim of the study was the comparison of phenetic diversity to the patter...
Context
Taxus woodlands suffer from a lack of natural regeneration across its whole distribution range.
Aims
In Knyazhdvir Reserve in Ukraine Taxus baccata primarily competes with Abies alba. It has been assumed that in the conditions of deep shade, yews have a greater competitive advantage than firs.
Methods
To verify this hypothesis, a plot with...
Juniperus excelsa M.-Bieb. is a major forest element in the mountains of the eastern part of Mediterranean and sub-Mediterranean regions. This study comprises the first morphological investigation covering a large part of the geographical range of J. excelsa and aims to verify the congruency between the morphological results and molecular results o...
Mediterranean junipers are of special ecological importance as key components of resource islands in semi-arid mountain ecosystems of the Mediterranean basin. The fragmentation of their habitat, which was primarily natural and driven by climatic drought conditions, is currently being aggravated by anthropogenic pressure. In the framework of this co...
Pinus uliginosa is an interesting taxon from the Pinus mugo complex with controversial systematic
position andspecific characteristics, intermediate among P. mugo, P. uncinata and P. sylvestris. The peat-bog
pine is rare andprotectedin Poland. All its’ known populations have a relict character andare slightly different
from each other. The aim of t...
The main aim of our study was to verify the influence of climatic factors on the formation of abnormal 3-needle dwarf shoots in the two-needle Pinus mugo. Twenty individuals of the species, which had at least one abnormal brachyblast in 2002, have been studied in the Tatra Mountains (Carpathians) and an additional 20 in the Giant Mountains (Sudetes...
Dioecy is a mating system in which a greater reproductive effort has been observed in one sex than the other. This is expressed in differences between the sexes in growth rate and spatial segregation. The spatial structure of Juniperus thurifera subsp. thurifera and Juniperus communis subsp. communis and growth rate of tree-ring width of J. thurife...
Taxus baccata L. is a rare and endangered dioecious species in Europe. Species of this mating system are considered to be the most vulnerable to extinction. It is believed that one reason for this state may be the uneven reproductive effort and different habitat requirements of the two sexes. Silver fir and European yew have very similar ecological...
We tested the performance of molecular markers and biometric traits in the identification of hybrids between closely related mountain pine (Pinus uncinata) and Scots pine (Pinus sylvestris). A plastid DNA marker and a set of morphological and anatomical needle traits were applied in analyses of individuals from several sympatric stands of the speci...
The taxonomie position of the population of tree-like, mostly polycormic individuals of pines from the Mshana peat bog in the Gorgany Mountains (East Carpathians, Ukraine) has been studied on the basis of the morphological characteristics of cones and needles, and anatomical characteristics of the needles. These features have been compared with the...
Hybridisation and introgression are expected to be common in plant populations composed of various species of the same genera. These processes, however, frequently have one direction or are asymmetric, when one of hybridising species is a donor and other recipient of pollen. The asymmetric hybridisation may be also an important manner of migration...
Sex ratio and sexual dimorphism were studied in the dioecious tree Taxus baccata. We examined five populations of T. baccata in Poland and Ukraine to identify the differences between male and female individuals. The sex of all individuals, height
and diameter, needle length and area, specific leaf area (SLA), the number of stomata rows, stomatal de...
The needle life span of evergreen coniferous trees is a species-specific trait but can be also affected and modified by environmental conditions. On the basis of field observations of needle life span during three periods in two populations of Pinus mugo in the Tatra Mts (altitude: 1600-1700 m) and Sudety Mts (altitude 830-1420 m), 11 populations f...
Differences in morphological and anatomical characters of needles between seedlings, saplings and adult trees of the endangered Pinus uliginosa from the Węgliniec Nature Reserve in SW Poland were examined biometrically and statistically assessed using the Student's t-test, Tukey–Kramer test, step-wise discrimination and agglomeration on Euclidean d...
The characters of Quercus robur and Q. petraea leaves are of main taxonomic value and the adult trees of both species can be distinguished on them. However, young individuals, mostly seedlings but also saplings, are told to be undistinguishable or only partly distinguishable on the leaf morphology. The aim of the study was to verify this hypothesis...
Juniperus excelsa and J. thurifera are considered to originate from the same ancestor. As a result of occurring in geographically isolated refuges –J. excelsa in SE Europe and SW Asia and J. thurifera in SW Europe and NW Africa – their divergence could have taken place at the end of the Tertiary, with the climate cooling. Juniperus foetidissima occ...
Taxus baccata L. is a rare and endangered species with restricted occurrence. One or two-year-old yew seedlings occur quite frequently in natural stands of the species, but older seedlings are rarely observed. Therefore we investigated the relationship between light intensity and the growth rate of ten-year-old seedlings of the European yew Taxus b...
The aim of the present study was to analyse the occurrence of monoecious individuals in selected populations of Taxus baccata in Poland and Ukraine. The investigation showed the monoecy in Taxus baccata to be extremely rare phenomenon. Only four cosexual individuals were found in three by seven populations examines and the frequency of monoecy was...
Needles from abnormal dwarf shoots of Pinus mugo are described. The three-, five-and seven-needle dwarf shoots were found in the Dolina Pięciu Stawów in the East Tatra Mts. The needles were measured and documented by photographing. Abnormal nee-dles were shorter, thinner and narrower than those of two-needle shoots. The shape of cross-section of th...
Questions
Question (1)
I am trying to remove wax from Populus tremuloides x P. tremula leaves. I tried to use methanol, chloroform, acetic acid, boiled water - nothing works. I want to do stomatal imprints, but just to put nail polish is not working because of the thick layer of wax. Maybe someone has more experience with this? Maybe someone knows how to extract all epidermis from the leaf?
