The association of beech and fir was researched on Mt. Suvobor, on serpentinite bedrock. In the past, the beech and fir forest on Suvobor was not studied, it was just referred to, so the objective of this paper was to study the floristic characteristics of this forest, which will enable its ecological-vegetational differentiation and widen the knowledge on beech and fir associations on serpentinites. The studied plant community is characterised by poor floristic composition and by the absolute domination of fir in the tree layer. In the life form spectrum, the dominant plants are phanerophytes, and the percentage of geophytes is increased, which points out the mesophilous plant community. The spectrum of floral elements indicates the dominance of the Central-European floral element, but also a significant percentage of some more xerophilous elements, which is the consequence of a specific parent rock.

Ecological and floristic characteristics of the new subassociation of the Balkan beech and Greek maple plant community with hornbeam (Aceri heldreichii-Fagetum subass. carpinetosum betuli) were studied. This subassociation is recorded and described on Mt. Rudnik, where it occurs at the elevations 950- 1,050 m, on moderate to steep inclinations (10-30?), and cold aspects: northern, northwestern and northeastern. Bedrock consists of sandstones and mudstones. The biological spectrum, ecological spectra and spectrum of distribution types of this community were calculated. The community has phanerophyte-hemicryptophyte character, it is mesophilous regarding soil moisture requirements and temperature requirements, it is neutrophilous to soil acidity, according to light requirements it is tolerant to semi-tolerant. The most numerous group of distribution types is Central European, which confirms the mesophilous character of this community.

This paper deals with the forest plant community of beech, fir and spruce (Piceo-Fago-Abietetum Colic 1965), which is the most widely distributed plant community on the territory of national park ?Tara?. Spectrum of life forms and floristic elements are specified for this community. Spectrum of life forms shows that hemicryptophytes are the most frequent, with high occurrence of geophytes, which is characteristic of this mesophilous plant community. Spectrum of floristic elements show that centraleuropean floristic element is dominant and that this plant community is under strong influence of subcentraleuropean region. Five subassociations are set apart on the basis of floristic composition and site conditions: typicum, drymetosum, aceretosum, pinetosum silvestrae and vaccinietosum. Spectrum of life forms is made for every subassociation separately in aim to compare their floristic compositions. Subassociations aceretosum and vaccinietosum are characterized by the highest occurence of phanerophytes, and the lowest occurence of this life form is represented in subassociation drymetosum. The highest occurence of geophytes is in subassociation aceretosum, and the lowest in pinetosum silvestrae and vaccinietosum. Occurence of hemicryptophytes is the highest in subassociations drymetosum and pinetosum silvestrae, and the lowest in aceretosum. Subassociation typicum is stable plant community, subassociations drymetosum and vaccinietosum grow on poorer sites, while subassociations aceretosum and pinetosum silvestrae represent degradation of beech, fir and spruce forest (Piceo-Fago-Abietetum Colic 1965).

Floristic Characteristics

A new motpellier maple (Acer monspessulanum L.) site was described in this paper, located on mountain Boranja, in forest management unit ?Istocna Boranja?, above Roguljski potok, on Glogovita kosa ridge. Montpellier maple occurs on elevations between 460 and 480 m a.s.l., on southwestern and western aspect, on very steep slopes with inclination 45? t? 50?. The site area is 874 m2, ?nd coordinates of site centre are: ?=19?13?49.0? and ?=44?25?21.33?. In this site, Montpellier maple occurs in a plant community of hop-hornbeam and manna ash, and considering that Montpellier maple was recorded in all three layers, and that it occurs abundantly in shrub and ground layers, a subassotiation with montpellier maple was set apart (?stryo carpinifoliae-Fraxinetum orni subass. ?ceretosum monspessulanii). According to floristic composition, most plant species belong to the submediterranean floral type, so this community represents an enclave of submediterranean vegetation in the belt of continental beech forests. The community is of azonal character, orographically-edaphically conditioned, and occurs in warmer aspects, on shallow and skeletal rendzina on oolithic limestones.

Successional Stages

The secondary birch and aspen forests of middle stages of succession of the central elevated part of the Southern Urals are studied. 4 subassociations, 1 community, and 7 variants in the alliances of Aconito-Piceion and Piceion excelsae are allocated. It is shown that the floristic composition of aspen and birch secondary forests in the age of 60—80 years is almost identical to the natural forests. However, a slight increase the coenotical role of light-requiring species of grasslands and hemiboreal forests in the secondary communities of the class Brachypodio-Betuletea was noticed as well as some reduction of role the shade-tolerant species of nemoral complex and species of boreal forests of the class Vaccinio-Piceetea. Dominant tree layer under the canopy of secondary series is marked by an active growth of natural tree species.

Zero Energy Buildings

There is an urgent need nowadays to reduce current levels of GHGs emissions. On the other hand the EU countries are largely dependent on energy imports and are vulnerable to disruption in energy supply which may in turn threaten the functioning of their current economic structure. The EU imported 54% of its energy sources in 2006 and this value was projected to increase even further by 2030. Reducing its import dependency is one of the EU’s main goals of the 20-20 by 2020 target – this legislative package is believed to reduce the expected imports of energy by 26% compared to the development before the 20-20 initiative.One of the most important environmental problems is the energy consumption of the buildings. Current paper shows that buildings built with industrialized technology can deliver large energy and GHG emission reductions at low costs.Only 1-2% part of the building stock is exchanged every year, so it is very important to increase the energy efficiency of the existing buildings, too.Present paper focuses on the buildings built with industrialized technology only, and their potential in nearly zero-energy buildings sector. Up till now the Central European support schemes concentrated most financial resources on buildings built with prefabricated technology. Present paper explains the past and present of the “panel” problem in Hungary with a short outlook to some other countries.

In the June number of ANTIQUITY Mr Sinclair Hood introduced to the readers of this journal the sensational find of the so-called Neolithic inscribed tablets from Transylvania. When this find was announced for the first time [I], it made a great impression upon everybody who appreciated its significance. It was a kind of deus ex machina which seemed to solve once and for all one of the crucial issues of Central European archaeology: the absolute chronology of the Neolithic Period.

During the past ten years a number of papers dealing with progressive regional metamorphism in the southern portion of New Zealand have been published. In the following pages a brief summary of the assemblages of minerals typical of the various metamorphic zones is given, but the writer's main object is to draw attention to certain mineralogical and structural peculiarities that appear to differ in some degree from what are usually regarded as the normal features of regional metamorphism in such classic areas as the Scottish Highlands and the Caledonian chain of Norway. The possibility that such departures from the normal may in some instances be connected with chemical peculiarities in the parent rock is suggested by such phenomena as the well-known general limitation of chloritoid, staurolite, and low-grade garnets to pelitic rocks of special chemical compositions. Other unusual features, especially when found to recur in widely separated regions, may well be governed by some particular combination of physical rather than chemical conditions.

Abstract Considering the spread of the grey wolf (Canis lupus) in Europe over the past 30 years, Luxembourg took some measures to prepare for the return of this apex predator, including the establishment of a management plan that notably addresses the issue of wolf depredation on livestock. Here we present the results of genetic analyses of putative wolf saliva, hair and scat samples collected from or near prey carcasses between 2015 and 2020. In two cases, the wolf was confirmed via DNA analysis: in July 2017 near Garnich and in April 2020 near Niederanven, both assigned to category C1 (hard evidence). A third case was classified as C2 (confirmed observation) based on prey carcass characteristics, while genetic analysis yielded no result. These are the first confirmed records of wolves in Luxemburg since 1893. Moreover, the two C1-cases originated from the Alpine (Garnich) and Central European (Niederanven) populations. Given similar developments in the neighboring countries and regions, we conclude that the area including the Benelux countries as well as Rhineland-Palatinate, Saarland and Northern France may well become a melting pot for wolves of the two aforementioned populations in the coming years and decades.

Ghorkhod Protected Area (GPA) is located in a transitional zone among different biogeographical units in North Khorassan Province, NE Iran. The study area is mainly a mountainous region in western extensions of Khorassan-Kopet Dagh floristic province. We investigated the floristic composition, life form spectrum and phytogeography of the study area through several random collection efforts and 200 vegetation samples (reléves) in selected vegetation types during 2007–2012. A total of 663 vascular plant species belonging to 367 genera and 81 families are recorded as native and naturalized in GPA. Angiosperms and Dicots are among the most diverse plant groups. The richest plant families are Asteraceae (88 species), Poaceae (78), Lamiaceae (45), Brassicaceae (43), Fabaceae (38), and Caryophyllaceae (32). The genera Allium L. (17 species), Astragalus L. (15) and Cousinia Cass. (12) are the richest ones, however, the majority of the species belongs to oligotypic and monotypic genera. Life form spectrum of the study area is dominated by hemicryptophytes (38.9%) and therophytes (23.4%). Allium transvestiens Vved., Agropyron desertorum Schult., Helictotrichon turcomanicum Czopanov and Piptatherum latifolium (Roshev.) Nevski are recorded as new to Iran. The core flora of the area has the Irano-Turanian origin. However, the wide-range and widespread elements are also well represented in the study area. GPA is inhabited by several endemic, rare and narrow-range plant species, indicating the biodiversity importance of the study area in NE Iran.
