This study presents the results of studies on the chemical composition of rhizomes of Nuphar lutea which were carried out from July 2006 to November 2007 (the samples were collected at two-week intervals from March to November 2007). The first indication of the start of the growing season was the growth of leaves in the apical part of the rhizomes. Clearly visible signs that marked the beginning of the growing season were unfolding of leaves, which became arrow-shaped. The leaves had already unfolded and were arrow-shaped (saggitate) on April 10th when the temperature of the bottom water layer was 7oC. It may be assumed, therefore, that the growing season began between the 28th March and 10th April 2007. The phosphates, nitrates, sodium, calcium, total iron and sulphates levels in the rhizomes declined just after the growing season had started. The total nitrogen content remained at a constant level whereas the amount of dissolved silica increased. Considerable changes in the macroelement contents were noted when Nuphar lutea was in full bloom (10th-24th June). The macroelement contents presented in the tables and diagrams were expressed on a dry matter basis. An additional table illustrates the macroelement contents expressed on a fresh matter basis. The problem of collecting rhizomes of polycormic plants is discussed.

Molt is an important life history event for mammals occurring in temperate and cold zones. In the present paper, I investigate the pattern, timing and duration of seasonal molts of the Cape hares Lepus capensis Linnaeus, 1798 in northern China, by tracing and scoring the process of each molt quantitatively. All the seasonal molts in both overwintering and juvenile hares went through a similar order: midback (together with nape), flanks, belly, upper tail, and legs. Yet, there was a relatively confused pattern of replacement during the heaviest molting period of overwintering hares, compared to a relatively uniform pattern among juvenile hares. Overwintering hares experienced a spring and a fall molt. The fall molt was already initiated prior to completion of the spring molt and had a relatively short duration. Juveniles born early in the year (before July), before their fall molt, had undergone a postnatal molt, but those born late (July to September) had not. The juvenile fall molt had already begun when the postnatal molt was at its later stages. These facts suggest that the time budget for fall molt is tight and seasonally constrained. The timing and duration of molts in the overwintering and early-born juvenile hares were independent of individual age. Among overwintering hares, both sexes started spring molt synchronously, but the females were behind the males in late period of this molt and consequently further delayed throughout subsequent fall molt. This may be related to a higher cost of reproduction in females. No sexual difference was found in the molting progress of juvenile hares.

On the basis of monthly averaged satellite data, this study examined how the annual cycle of the Baltic Sea surface temperature (SST) varied spatially and temporally during the period 1986–2005. We conclude that there are two main thermal seasons in the Baltic Sea separated only by short transitional periods – spring lasting about one month, and autumn lasting two months. Generally speaking, summer covers the part of the year from June to October with the highest monthly mean SST in August. Winter, with a minimum monthly mean SST in February in shallow waters or in March in deeper areas, lasts from December to April. As a result of climate changes over the Baltic Sea region, strong positive trends in SST occur in the summer months. In consequence, the period with extremely high sea surface water temperatures has become slightly longer in the central Baltic. In the last decade winter changes in SST display zero or even negative tendencies. The investigated period was characterized by an annual increase in mean temperatures of about 0.03–0.07◦C. However, the rates of monthly mean SST changes were sometimes more than three times as high.
