Water quality parameters of floodplain lakes may be indicative of the intensity of groundwater recharge. The main assumption made in the study is that the direct influence of groundwater recharge is reflected in the vertical gradient of temperature and aeration along the whole water column. Considering this, we seasonally monitored physical and chemical properties of 22 oxbow lakes in postglacial river valleys (the Słupia, Drwęca and Łyna rivers) in temperate climate zone in the southern watershed of the Baltic Sea (N Poland). The results were compared with groundwater samples from transects of piezometers located near the floodplain lakes. The floodplain water bodies showed variability (both in vertical and spatial dimensions) in temperature, aeration and electrolytic conductivity, affected mainly by different sources of water supply. The temperatures and dissolved oxygen contents declined not only with the increasing depth of water and a distance from the river channel, but also a significant drop in the parameters’ values have been associated with groundwater recharge within the floodplain edge.

The thermal regime of a phonolite scree slope on Klíč Mt., North Bohemia, Czech Republic, was monitored by miniature data loggers. The spiders were collected throughout the entire scree field area and on the adjacent cliff. In 2005 and 2006, the mean internal temperatures at the lower margins of the scree slope were 0.1 and 0.5°C, whereas the mean external ambient temperatures were 6.8 and 7.2°C, respectively. The difference, therefore, is 6.7°C. The long-term cooling of the basal portions, along with the winter heating of the central and upper parts of the scree, are the most specific microclimatic phenomena. The boreomontane species inhabit the extremely cold vents at the lower margins of the scree slope. Species of alpine origin inhabit the middle portions of the scree slope. Six thermophilous species inhabit the sun-exposed rock margins of Klíč Mt., which is nearly at the uppermost limit of their vertical distribution in the Czech Republic.
