Darbo tikslas: nustatyti lapuočių miškų augalų kitimą vegetacijos sezono metu botaniniame – zoologiniame Kamšos draustinyje. Darbo objektas: Kamšos botaninis – zoologinis draustinis, esantis prie Kauno miesto ir apimantis 321 ha. plotą. Kamšos botaninis – zoologinis draustinis botaniniu požiūriu ypatingas. Čia vyrauja lapuočiai, sudarydami mišrius Tilia cordata, Carpinus betulus, Populus tremula, kai kur Quercus robur. Žolinei augalijai būdinga didelė rūšių įvairovė. Dažniausiai sutinkamos: Aegopodium podagraria, Ranunculus ficaria, Lamiastrum galeobdolon, Corydalis solida, Anemone ranunculoides, Asarum europaeum, Gagea lutea. Darbo metodai: rudenį buvo parinkta dešimt 1x1 dydžių barelių. Tyrimo bareliai buvo išdėstyti taip, kad apimtų kuo daugiau augalų rūšių. Tyrimai atlikti 2006 m. vegetacijos sezono metu būdingame plačialapių lapuočių medyne. Buvo fiksuojamos fenologinių reiškinių pasirodymo fazės, taip pat projekcinis padengimas ir augalų aukštis. Iš stebėjimo duomenų sudaryti vegetacijos ir žydėjimo spektrai. Siekiant išaiškinti mikroklimatinių sąlygų įtaką augalijos augimui ir vystymuisi vegetacijos laikotarpiu išanalizuoti temperatūrų ir kritulių duomenys. Darbo rezultatai: Atlikus tyrimus, nustatyta, kad vegetacijos laikotarpiu kinta augalų rūšių projekcinis padengimas. Didžiausias projekcinis efemeroidų (Anemone ranunculoides, Anemone nemorosa, Corydalis solida, Ficaria verna) padengimas buvo pavasarį. Vasarą daugiausia dengė Mercurialis perennis, Polygonatum...

The object of this work: is Kamša zoological-botanical reserve situated near Kaunas. Area of reserve is 321 ha. The Kamša zoological-botanical reserve is exclusive, by biological point of view. There dominate deciduous: Tilia cordata, Carpinus betulus, Populus tremula, in some places Quercus robur. In herbaceous vegetation dominate: Aegopodium podagraria, Ranunculus ficaria, Lamiastrum galeobdolon, Corydalis solida, Anemone ranunculoides, Asarum europaeum, Gagea lutea. The methods of this work: were picked - up ten bartels of 1x1 size in autumn. The place of barels was chosen so, that in them will be involve as many species as posible. Investigations were done during vegetation period of 2006 year. The dates of phenological appearance, projection cover and herbaceous height were recorded. The spectra of vegetation and flowering were made. Data on temperature and precipitation was analysed with the purpose to determinate the influence of microclimatic conditions on plants growth and development. The results of this work: It was determined, that projection cover of the plants changed during the vegetation period. The largest projection cover of the ephemeroids Anemone ranunculoides, Anemone nemorosa, Corydalis solida, Ficaria verna was in spring. Mercurialis perennis, Polygonatum multiflorum, Aegopodium podagraria, Pulmonaria... [to full text]

Grigaitis V. 2004. The forest community dynamics in the edges of different age of Vaccinio - myrtillosa pine forests. The Master thesis / superwisor doc. dr. V. Marozas. LŽŪU, Akademija, 98 p.: iliustr. 52. SUMMARY The purpose of work: to study the appearing of the edge effect among cuttings and neighboring with them mature stands by performing clear - cuts in site in the red whortleberry - whortleberry pine forests; the meaningful influece of the edge effect for cuts and the correlation of forest community components of mature stands: for the sprouts of ligneous plants, moss and lichen, herbal plants, underbrush and understorey, the canopy cover in respect of time and space. The subject of work: Kačerginė forest district of Dubrava Forest Enterprise, the forest array of Zapyškis, pine forests of Vaccinio - myrtillosa site types. The total area of the forest district is 2414 ha, of which the forest array of Zapyškis covers 1568 ha. The object is in the Northeastern part of Middle Europe geographically, in regard to plant formation - in the Europe mixed up - forests zone, from the point of geomorphological view forest reserve belongs to East Europe west side part plaines. The methods of work: for the research in pine forests of Vaccinio - myrtillosa site types were sampled five clear - cut tracts of different cut age, neighboring with conditionally of the same age pine stands of Vaccinio - myrtillosa site types. In the each cut and mature stand group( in the couple)... [to full text]
