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)

The history of littoral zone research in the Neva estuary, the largest estuary in the Baltic Sea, is described. Environmental problems, including effects of eutrophication and introductions of alien species, are discussed. A brief outline of future research is provided. The Neva estuary is the largest estuary in the Baltic Sea, located in the eastern Gulf of Finland. It has sustained a heavy impact from human activities, including discharges of treated and untreated wastewaters from point sources in St. Petersburg and intensive ship traffic. The Neva estuary consists of three main parts: Neva Bay (surface area 400 km 2 ), and the inner and outer estuaries (total surface area of the last two parts about 3200 km 2 ) (Pitkanen, 1991). Since the early 1980s freshwater Neva Bay has been separated from the brackish lower reaches of the estuary by a storm-surge barrier, which is still under construction (Fig. 1). The coastal zone of the estuary is intensively exploited for recreation (specifically in the Resort District of St. Petersburg), sport and commercial fishing, military purposes, and various industrial uses including nuclear power and shipping. The coastal zone also receives discharges of treated and untreated wastewaters, occurring mainly in the lower Neva River and in Neva Bay. Heavy nutrient loading (eutrophication), mainly from point sources in the Neva River and the upper estuary, is currently the most serious environmental problem for the Neva estuary and adjacent parts of the eastern Gulf of Finland (Alimov et al., 1996; Leppanen et al., 1997). The introduction of alien species is an emerging issue for the Neva estuary (Alimov et al., 1998; Orlova et al., 1999b; Panov et al.,
介绍了波罗的海最大的河口涅瓦河河口沿岸带研究的历史。讨论了环境问题，包括富营养化的影响和外来物种的引入。对今后的研究作了简要概述。涅瓦河河口是波罗的海最大的河口，位于芬兰湾东部。它受到人类活动的严重影响，包括从圣彼得堡的点源排放经过处理和未经处理的废水以及密集的船舶交通。涅瓦河河口由三个主要部分组成:涅瓦湾(面积400平方公里)和内外河口(后两个部分的总面积约3200平方公里)(Pitkanen, 1991)。自20世纪80年代初以来，淡水的涅瓦湾已经被一个仍在建设中的风暴潮屏障与河口的咸淡水下游分开(图1)。河口的沿海地区被集中开发用于娱乐(特别是在圣彼得堡的度假区)，体育和商业捕鱼，军事目的，以及各种工业用途，包括核电和航运。沿海地区还排放经过处理和未经处理的废水，主要发生在涅瓦河下游和涅瓦湾。主要来自涅瓦河和河口上游点源的重营养负荷(富营养化)是目前涅瓦河河口和芬兰湾东部邻近地区最严重的环境问题(Alimov et al.， 1996;Leppanen et al.， 1997)。外来物种的引入是涅瓦河河口的一个新问题(Alimov et al.， 1998;Orlova et al.， 1999;Panov等人，

Short-term effects of different doses (0.25 and 0.5 kg m -2 ) of wood ash fertilization in a field experiment in a 20-year-old Scots pine stand on a nutrient-poor sandy soil (Arenosol) was studied in North Estonia. Soil chemical properties, nutrient accumulation, soluble carbohydrates, starch, hemicellulose, cellulose, and lignin were used as biochemical indicators for the assessment of the state of trees from 2000 until 2005. Changes in the soil upper horizon (30 cm) showed an increase in the pH and in the concentrations of K, Ca, B, Mg, and other elements, except N, after treatment. Statistical relationships were found between the doses of wood ash used in the treatment and the mineral composition of the soil. Changes in soil properties brought about changes in nutrient accumulation into trees and the needle diagnosis showed an essential increase in the K, Mg, Fe, Mn, and Zn concentrations in needles. No statistically significant changes were observed in the concentrations of soluble carbohydrate (tendency to decrease), starch (tendency to increase), and structural carbohydrates, but a somewhat higher accumulation of cellulose and lignin was registered in the needles of Scots pine. The effect of wood ash on carbohydrate metabolism and lignin synthesis seemed to depend on the seasonal development stage of needles and climatic conditions.
在爱沙尼亚北部营养贫乏的沙质土壤(Arenosol)上，对一个20年的苏格兰松林进行了田间试验，研究了不同剂量(0.25和0.5 kg m -2)木灰施肥的短期效应。2000 - 2005年以土壤化学性质、养分积累、可溶性碳水化合物、淀粉、半纤维素、纤维素和木质素为生化指标评价树木的生长状况。土壤表层(30 cm)的变化表明，处理后土壤pH升高，K、Ca、B、Mg和除N外的其他元素的浓度升高。在处理中使用的木灰剂量与土壤的矿物组成之间发现了统计关系。土壤性质的变化导致树木养分积累的变化，针叶诊断显示针叶中K、Mg、Fe、Mn和Zn的含量显著增加。可溶性碳水化合物(有减少趋势)、淀粉(有增加趋势)和结构性碳水化合物的浓度没有统计学上的显著变化，但苏格兰松针中纤维素和木质素的积累有所增加。木灰对碳水化合物代谢和木质素合成的影响似乎取决于针叶的季节发育阶段和气候条件。
