BACKGROUND A series of preliminary research projects on plants used in Calabria (Southern Italy) in veterinary science and in other ethno-botanical fields (minor nourishment, domestic and handicraft sector) was carried out in the last twenty years. From the ethno-botanical point of view, Calabria is one of the most interesting region, since in the ancient times it was subject to the dominant cu...
Survival and growth of white spruce (Picea glauca (Moench) Voss) seedlings raised as 4 different-sized container stock types were followed on 5 harvested sites in the Cache Creek drainage of interior Alaska. Stock types evaluated were 1-0 Ray Leach Pine Cells® (65 cm3, 4 in3) and 1-0 Styroblock® sizes 313B (65 cm3, 4 in3), 415B (98 cm3, 6 in3), and 415D (164 cm3, 10 in3). After 5 y, survival an...
Recent observations and model simulations have highlighted the sensitivity of the forest-tundra ecotone to climatic forcing. In contrast, paleoecological studies have not provided evidence of tree-line fluctuations in response to Holocene climatic changes in Alaska, suggesting that the forest-tundra boundary in certain areas may be relatively stable at multicentennial to millennial time scales....
On two occasions, with a 10or 11-year interval, species occurring in 650 plots (100 m) in boreal production forests in Sweden were recorded within a monitoring program. During this interval, many of the plots had been subjected to varying degrees of timber extraction. The presence of 49 vascular plant species or species groups was recorded and we evaluated how species number varied over time. T...
