The object of the work was Kamsha zoological-botanical reserve situated near Kaunas. Investigations were done during vegetation periods in 1991, 2000, 2006 and 2006. The dates of phenological appearance and projection cover were recorded. The spectra of vegetation and flowering were made. The data on temperature and precipitation was analysed with the purpose to determinate the influence of climatic conditions on the growth and development of plants. It was determined, that vegetation of herbs started at the beginning of April (12th-13th week). Intensive vegetative development started at the 14th week in 1991 and 2007, and at 16th week in 2000 and 2006. In 2006 projection cover of herbs showed two picks – one in spring time and other in August. Projection cover in 2000 decreased during dry period in September. In the coldest spring (2006) flowering of herbs started two weeks later than in years of 1991 and 2000. In the warmest year (2007) flowering of herbs started two weeks earlier than in years of 1991 and 2000. In the warmest year (2007) foliation of trees started and completed 2 weeks earlier than in 2000 and 2006. In 1991 foliation of trees started 2 weeks later, but completed about at the same time like in 2000 and 2006. The majority of plants flowered in spring when trees were without leaves and light conditions were good. 3 5TH INTERNATIONAL CONFERENCE “RESEARCH AND CONSERVATION OF BIOLOGICAL DIVERSITY IN BALTIC REGION” , Book of Abstracts, Daugavpils, 22 – 24 April, 2009 THE PARTICULAR QUALITIES OF EMBRYOGENESIS AND ORGANOGENESIS FOR DIFFERENT GENOTYPES OF RED CLOVER IN VITRO Jekaterina Akentjeva Daugavpils University, vienibas str.13, Daugavpils, Latvia, [email protected] Red clover is important forage in Latvia, and because of this it is important to research it more deeply and to complete the knowledge we have. One of the methods of research is observation of embryogenesis and organogenesis in tissue cultures. This method plays an important role in agriculture and its development, because when we use it, we are able to observe increased variability in a short period of time. It gives us an ability to create new sorts with the best requirements. The goal of this research is to understand embryogenesis and organogenesis principles, use their capacity, and create viable and more developed red clover embryos by using the method of tissue culture. 4 5TH INTERNATIONAL CONFERENCE “RESEARCH AND CONSERVATION OF BIOLOGICAL DIVERSITY IN BALTIC REGION” , Book of Abstracts, Daugavpils, 22 – 24 April, 2009 THE SCARABAEIDAE FAMILY (COLEOPTERA: SCARABAEIDAE) IN FAUNA OF LATVIA Kristina Aksjuta Daugavpils University, Institute of Sistemaic Biology, Daugavpils, Vienības str.13, Latvia, [email protected] The Scarabaeidae family (Coleoptera: Scarabaeidae) is comparatively rich in species, nevertheless this family in Latvia is not investigated enough. There are 86 species of 37 genus and five tribes (Aphodiini, Psammodiini, Hopliinae, Cetiniinae, Trichiinae) found in Latvia. Some of these species (Aphodius pictus Sturm., A. piceus Gyll., A. tomentosus Müll., A. obscurus F., A. scrofa F. , A. melanostictus Schm. etc.) are not noted in Latvia last 100 years, so they can be accounted only theoretically. Several scarabid species in Latvia are specially protected (Osmoderma eremita Scop., Gnorimus nobilis L. Gnorimus variabilis L., Protaetia marmorata F.) by Regulations of Cabinet of Ministers No. 396 “List of Specially Protected Species and Species with Exploitation Limits”. From these Osmoderma eremita Scop., Gnorimus nobilis L. Gnorimus variabilis L. are species, which requires establishing of micro-reserves (Regulations of Cabinet of Ministers No. 45 “Establishment, Protection and Management of Micro-reserves”). Osmoderma eremita Scop. is included in II annex of Bern Convention and EU Species and Habitat directive (II, IV pielikums, 92/43/EEC) as well. A. prodromus Brahm., A. rufipes L., A. fimetarius L., A. fossor L., A.depressus Kugel., Serica brunnea L., Trichius fasciatus Fabr., Cetonia aurata L. and other scarabid species are widespread in all territory of Latvia and in known localities are found in multitude. Several scarabid species (Maladera holosericea Scop., Rhyssemus germanus L., Polyphylla fullo L. etc..) reach their limit of distribution area in Latvia, therefore are quite rare. The genus Aphodius is richest in species in Scarabeidae family. There are 44 species represented of this genus in Latvia. There are 1712 specimen of Scarabeidae family collected, processed and identified. Fifty four species from 21 genera are recognized in these findings and in beetle collection of Systematic Biology Institute of Daugavpils University. Two of them are specially protected species (Gnorimus nobilis L., Protaetia marmorata Farb.). There are new locality found for one of these (P.marmorata Fabr.) – Aizkraukle district, Mazzalve municipality. The most representative in collection are A.rufipes L. (100 specimen), Cetonia aurata L. (65), Serica brunnea L. (61), A.fimetarius L. (54), rare are Oryctes nasicornis L. (21), Copris lunaris L. (7), Polyphylla fullo (1). 5 5TH INTERNATIONAL CONFERENCE “RESEARCH AND CONSERVATION OF BIOLOGICAL DIVERSITY IN BALTIC REGION” , Book of Abstracts, Daugavpils, 22 – 24 April, 2009 SMALL MAMMAL COMMUNITIES IN THE NORTHERN LITHUANIA Paulius Alejūnas, Vitalijus Stirkė Institute of Ecology of Vilnius University, Akademijos 2, Vilnius, Lithuania, [email protected] Investigations were done in August – November 2008 in northern Lithuania, Kamanos strict nature reserve, Žagarė Regional Park and in seven other administrative districts. Small mammals were snap-trapped using standard lines of 25 snap traps. In total, 1187 small mammals of 13 species were trapped. Bank vole (Myodes glareolus) was dominant species – 28.9% of the total catch, yellow-necked mouse (Apodemus flavicollis) and striped field mouse (Apodemus agrarius) – subdominants, 20.0% and 15.3%, respectively. Rarest species, with less than 2% share were water shrew (Neomys fodiens), house mouse (Mus musculus), pygmy field mouse (Apodemus uralensis), harvest mouse (Micromys minutus) and northern birch mouse (Sicista betulina).
