First record of the Greek clouded yellow Colias aurorina Herrich-Schäffer, 1850 (Lepidoptera: Pieridae) for Albania
No full textDuring our field survey in the south-eastern part of the Republic of Albania, we encountered the Greek clouded yellow (Colias aurorina) at two sites, representing the first record for the species in Europe outside
Greece. It was found common at one site on the Albanian side of the Grammos Mts. with possibly continuous
range into northern Greece. As larval host plant of the Greek clouded yellow Astragalus thracicus was present in
abundance on the northern slopes of the mountain, we consider the species as not threatened in Albania. In
addition, the purple emperor (Apatura iris) and the Balkan green-veined white (Pieris balcana) were recorded for the first time in Albania

No full textAn overview of alien Diptera in Slovenia
No full textThe nonindigenous Diptera occurring in Slovenia are overviewed based on literature data. In total, 18 species belonging to eight Diptera families are alien to Slovenia. Most of the species originate from North America and continental Asia. The first record of an alien Diptera species (Ceratitis capitata (Wiedemann, 1824) (Diptera: Tephritidae)) was made in 1959, but the bulk of the species were recorded for the first time in the last two decennia. Most of the species were found in the pre-Alpine and sub-Mediterranean regions. The distribution and abundance of the alien Diptera are not fully known, as in most cases only the first observations were published. Most of the species are phytophagous and are known pests in agriculture and forestry. A list of expected nonindigenous Diptera species for Slovenia is given. It is suggested that a monitoring system should be developed in order to understand the population dynamics and the impact of the alien species on the ecosystem and economy

No full textDynamic conservation of forest genetic resources (FGR) means maintaining the genetic diversity of trees within an evolutionary process and allowing generation turnover in the forest. We assessed the network of forests areas managed for the dynamic conservation of FGR (conservation units) across Europe (33 countries). On the basis of information available in the European Information System on FGR (EUFGIS Portal), species distribution maps, and environmental stratification of the continent, we developed ecogeographic indicators, a marginality index, and demographic indicators to assess and monitor forest conservation efforts. The pan-European network has 1967 conservation units, 2737 populations of target trees, and 86 species of target trees. We detected a poor coincidence between FGR conservation and other biodiversity conservation objectives within this network. We identified 2 complementary strategies: a species-oriented strategy in which national conservation networks are specifically designed for key target species and a site-oriented strategy in which multiple-target units include so-called secondary species conserved within a few sites. The network is highly unbalanced in terms of species representation, and 7 key target species are conserved in 60% of the conservation units. We performed specific gap analyses for 11 tree species, including assessment of ecogeographic, demographic, and genetic criteria. For each species, we identified gaps, particularly in the marginal parts of their distribution range, and found multiple redundant conservation units in other areas. The Mediterranean forests and to a lesser extent the boreal forests are underrepresented. Monitoring the conservation efficiency of each unit remains challenging; however, <2% of the conserved populations seem to be at risk of extinction. On the basis of our results, we recommend combining species-oriented and site-oriented strategies
Performance of copper-ethanolamine-impregnated Scots Pine wood during exposure to terrestial Microorganisms
Get PDFoai:generic.eprints.org:5Copper-ethanolamine-based wood preservatives are still the most important solutions for protecting wood in ground applications in Europe. Wood in the ground is exposed to a variety of organisms that can act synergistically. In order to simulate these conditions in the laboratory, Scots pine(
Pinus sylvestris) specimens impregnated with copper
-ethanolamine preservative of three different concentrations (cCu= 0.125%, 0.25%,and 0.5%)were exposed to three different soils according to procedure ENV 807, for periods between 12 and 32 weeks. After the relevant period of exposure, samples were isolated, and their mass loss, bending strength, and modulus of elasticity were determined. In the final step, the remaining copper in the samples was determined. The results showed that, in spite of significant copper leaching, the tested copper ethanolamine-treated wood exhibited good performance in
ground applications. Furthermore, a good correlation was found between the mechanical properties and mass loss, regardless of the chemical treatment applie
