The group of cetrarioid lichens with globose ascospores includes 37 species from eight genera. Phylogenetic analysis, using program PAUP 3.1.1, was carried out on two different data sets – morphological (incl. anatomical and chemical) and molecular characters (ITS1, 5.8S, and ITS2 rDNA sequences) – to verify the correspondence of current taxonomy to the probable evolution of the taxa involved. The paraphyletic nature of the genus Allocetraria in regard to two species of Dactylina is assumed based on morphological characters. Still, the separation of these genera is strongly supported by the analysis of molecular data. The genus Tuckermannopsis (11 species) is paraphyletic in regard to Esslingeriana idahoensis and “Nephromopsis” weii. Monophyletic origin can be declared only for the Tuckermannopsis ciliaris group. The analysis based on molecular characters exhibits the monophyletic origin of the group including three Tuckneraria species. Monophyly of the genus Ahtiana was not supported by the analysis of morphological data. (Less)

Vertical migrations of Mysis mixta, M. relicta, and Neomysis integer were studied in the north-eastern part of the Gulf of Riga during May-September 1999. All three mysid species performed diel vertical migrations. These migrations were more intense in late summer and autumn than in spring and early summer. The proportion of juveniles and small-sized adults (< 11 mm) in the vertical migrations was higher than that of adults. Usually N. integer appeared in the water column first in the evening, followed later by Mysis spp. Both Mysis spp., often referred to as cold stenotherms, were found in high abundance in the surf ace waters in spite of very strong temperature gradients.

The aim of the experiments was to elucidate the influence of the treatment of alvar and peaty soils with different doses of wastewater sludge on the development of seedlings of silver birch (Betula pendula) under experimental conditions. Sludge from Tallinn Wastewater Treatment Plant used had passed methane fermentation and centrifugal drying. The content of dry matter in the sludge was 50.7%. The concentration of nutrients in the sludge was high: N 2.06%, P 2.76%, and K 0.28%. The experiments were conducted on the territory of Tallinn Botanical Garden. For experiments 10 L plastic pots containing soil and peat mixtures with different concentrations of wastewater sludge (8.9; 26.6, and 44.3 kg/m 2 d.m.) and control variants were used. As a rule, treatment with sludge causes stress in seedlings during the period after planting inhibiting their growth and development. As compared to peat substrates, mineral soils are notably more sensitive towards treatment with wastewater sludge, and stress in plants in the first year is caused by considerably smaller doses of sludge. In spring 2005 the variant with 5 kg wastewater sludge added to soil per pot died completely; also the variants with 3 kg sludge added to soil and 5 kg sludge added to peat should be regarded as dead. In the second year a positive effect of wastewater sludge was observed in the peat variants. By the end of the second year of growth the morphological parameters of different variants changed significantly. The dry mass was the greatest in the variants with 1 kg and 3 kg wastewater sludge added to peat, exceeding the control variant 4.1 and 3.7 times, respectively. In all the variants the proportion of roots in the total dry mass increased.
本试验的目的是阐明不同剂量的污水污泥处理桤木土和泥炭土对实验条件下白桦幼苗发育的影响。塔林污水处理厂的污泥经甲烷发酵和离心干燥处理。污泥中干物质含量为50.7%。污泥中养分浓度较高:N 2.06%， P 2.76%， K 0.28%。实验是在塔林植物园进行的。实验用10升塑料盆装不同浓度的废水污泥(8.9;26.6和44.3 kg/m (2dm)和对照变异。通常，用污泥处理会在种植后的一段时间内对幼苗造成胁迫，抑制它们的生长发育。与泥炭基质相比，矿质土壤对废水污泥的处理明显更敏感，并且在第一年对植物的胁迫是由相当小剂量的污泥引起的。2005年春季，每盆土壤中加入5公斤废水污泥的品种完全死亡;此外，向土壤中添加3公斤污泥和向泥炭中添加5公斤污泥的变体应被视为死亡。第二年，在泥炭变体中观察到废水污泥的积极影响。在生长第二年结束时，不同变异的形态参数发生了显著变化。在泥炭中添加1 kg和3 kg污泥的变异中，干质量最大，分别是对照变异的4.1和3.7倍。在所有变异体中，根占总干质量的比例都增加了。
