The results of faunistical and ecological research on beetles (Coleoptera) of Curonian Spit were presented in this work. A species composition of different habitats: Baltic sea coastal area and the foredune ridge,wooded dunes, humid dune slacks, white and grey dunes and Curonian lagoons was established on the basis of research. The greatest species diversity was established in humid dune slacks (234 species), the lowest species diversity was established eudominant, dominant, subdominant and accessory species in the four Curonian Spit habitats: wooded dunes, humid dune slacks, grey dunes and littoral Curonian lagoons. The distribution and diversity of rare and protected insects species in Curonian Spit were established. There were found 10 species of beetles new for Lithuanian fauna:Elaphropus parvulus, Pterostichus ovoideus (Carabidae), Enochrus bicolor (Hydrophilidae), Lomechusa emarginata, Quedius infuscatus (Staphylinidae), Negastrius arenicola, Cardiophorus asellus (Elateridae), Obrium brunneum (Cerambycidae), Dicranthus elegans, Glocianus moelleri (Curculionidae). The beetles of 4 species: Cicindela maritima, Calosoma inquisitor (Carabidae), Polyphylla fullo (Scarabeidae), Stenagostus rufus (Elateridae)wee included in Red Data book of Lithuania and the beetles of 11 species - in List of Key forest habitats species.

Darbo objektas: turizmo klasterio formavimas Kuršių nerijoje. Darbo tikslas: išanalizuoti turizmo klasterio formavimo prielaidas Kuršių nerijoje. Darbo uždaviniai: 1. Išanalizuoti turizmo svarbą regiono plėtrai. 2. Pateikti klasterių formavimosi prielaidas. 3. Atskleisti klasterių vaidmenį regiono konkurencingumui. 4. Įvertinti turizmo klasterio formavimo(si) Kuršių nerijoje galimybes. 5. Sukurti Kuršių nerijos turizmo klasterio modelį. Tiriamasis klausimas: kokios yra turizmo klasterio formavimo prielaidos Kuršių nerijoje? Hipotezė: rekreacijos plėtros procesai Kuršių nerijoje suformuoja prielaidas atsirasti turizmo klasteriui šiame regione. Svarbiausios išvados: • Siekis tapti produktyvesne ir pelningesne įmone bei turėti ilgalaikę veiklos perspektyvą yra svarbiausia priežastis, kodėl įmonės stengiasi tapti klasterio narėmis. Glaudūs klasterio narių tarpusavio ryšiai padidina atskirų narių veiklos efektyvumą, todėl ir galutinis bendras rezultatas yra didesnis nei tas, kuris būtų, jei kiekvienas narys veiktų atskirai. Klasteriai įvairiais aspektais padeda spręsti kvalifikuotų ir motyvuotų darbuotojų stygiaus ar kitų specializuotų išteklių problemą, sukuria prielaidas koncentruoti narių finansinius išteklius bendriesiems projektams, be to, klasterizuotuose regionuose formuojasi informaciniai tinklai, kuriais sklinda visa įmonėms aktuali tiek formalaus, tiek neformalaus pobūdžio informacija, specializuotos žinios. • Klasteriai regionų konkurencingumą veikia padidindami...

The objectives of the study: 1. To analyze the importance of tourism to the region's development. 2. To present assumptions of cluster formation. 3. To reveal the role of clusters to regional competitiveness. 4. To rate tourism cluster formation opportunities in Curonian spit. 5. To create tourism cluster model of Curonian spit. Research question: what are the preconditions for the emergence of the tourism cluster in Curonian spit? Hypothesis: recreation development processes in Curonian spit forms the preconditions for the emergence of a tourism cluster in the region. Main conclusions: Desire to become more productive and more profitable company and have a long term business perspective is the main reason why companies are trying to become cluster members. The close ties between members of the cluster increases the efficiency of the individual members, so the final total result is greater than that which would be provided by each member alone. Clustering helps to deal with various aspects of qualified and motivated staff shortages or other specialized resources problem. It creates preconditions for members to concentrate financial resources for common projects, by the way in addition to clustered regions forming of the information networks, which is spreading all relevant enterprises in both the formal and informal information...
