Opis:
The beginning dates and the lengths of thermic seasons in Warsaw (1951-2004) were analysed. These characteristics of seasons are very variable, especially in winter. The changes of winter length influence strongly the dates and length of adjacent seasons, that is, of early winter and early spring. The current warming is best visible exactly during these seasons: winter becomes shorter, while early winter and - to an even longer degree -early spring become longer. The period of spring, summer and autumn is characterised by grater stability. These seasons showed a very weak tendency to change on even its lack, both as regards the length and the beginning date.

Opis:
A newcomer to the Baltic Sea, the Chinese mitten crab is especially abundant in the Szczecin Lagoon (NW Poland), where it was first reported in 1927. Body weight, and carapace width and length, were studied in 647 individuals collected with fyke nets in the Szczecin Lagoon from 30 March – 18 April2001 and from 5–21 November 2001. 51.01% of the 543 autumn specimens were males, but only 30.97% of the 113 spring specimens were males. Body weight varied from 45.1 to 306.5 g, carapace length from 41.07 to 81.02 mm and carapace width from 46.68 to 88.85 mm. The autumn crabs were significantly heavier than the spring specimens.

Opis:
Postharvest balsam fir trees are known to suffer a number of problems that may be linked to abscission rates, such as dehydration or wounding. By definition, postharvest balsam fir trees are also detached from roots and will no longer be supplied certain root derived factors normally translocated via the xylem. Resupplying those root derived factors may delay abscission. The objective of this experiment was to take sap from a root intact species (i.e. Acer saccharum L) and add it to the water supply of balsam fir branches. Further, the effect of reverse osmosis and autoclaving the sap supply will be explored. The experiment was conducted once in spring and again in autumn to examine seasonal changes in needle abscission. The only hormones found in the maple sap were ABA and its metabolites, with PA (163.0 ng g–1) being the primary metabolite present. Needle retention was higher in branches harvested in autumn, as long as they were provided a sap that did not undergo RO. If the sap had undergone RO, then needle retention was slightly decreased in autumn. Needle retention generally decreased as the concentration of maple sap in the water supply increased and this trend was accelerated if the sap had undergone RO. Autoclaving the sap successfully delayed the length of time for water consumption to decrease, but this unexpectedly did not translate into improved needle retention.

Opis:
One of the variables oscillating seasonally in Helix pomatia L., described in our previous paper, was their rudimentary cryoprotection provided by modest increases in haemolymph glucose and glycerol concentrations in autumn and early spring, respectively. Because factors governing cryoprotective responses are unknown, we decided to investigate the effects of spring and autumn acclimation of H. pomatia to different thermal and photoperiod conditions on the changes in haemolymph concentrations of glucose and glycerol and on the glycogen level in selected organs. Neither acclimation to short-day photoperiod nor low ambient temperature evoked increase in glucose and glycerol concentration in spring and autumn. Both acclimation variants decreased hepatopancreatic glycogen level. The rudimentary freeze-tolerance in H. pomatia seems to be a combined effect of cold and short-day photoperiod and might also be affected by their nutritional and reproductive status. The effect of exposure to frost-bite is also likely to be involved.
