The length and weight growth of carp (Cyprinus carpio L.) from artificial lake Slatino [The Former Yugoslav Republic of Macedonia]
2001
Talevski, T. (Hidrobioloski zavod, Ohrid (The Former Yugoslav Republic of Macedonia))
In this paper are presented the length and weight growth of carp (Cyprinus carpio L.) from artificial lake Slatino (The Former Yugoslav Republic of Macedonia). Artificial lake Slatino because some recontruction works was whole emplied in 1993. Than all fish population was leaved in the river Mramorechka. Artificial lake Slatino has been stocking with individuals of carp (Cyprinus carpio L.) catch from Lake Ohrid. They are used for reproduction and in first years were used for reparation of the fish fond in artificial lake.

We studied the effects of elevated CO2 and elevated temperature on photosynthesis and composition of Scots pine needles during three years of treatments, started in August 1996. CO2 and temperature were elevated day- and year- round in closed-top chambers, which were constructed around naturally regenerated Scots pine trees growing at a nitrogen poor site. Our aim was to study, whether there is photosynthetic acclimation during three years of growth at elevated CO2 and elevated temperature in Scots pine, and whether acclimation response is connected to the aging of the needles

The future productivity of forests will be affected by combinations of anthropogenic stresses including elevated atmospheric CO2 and O3. Because the productivity of forests, will be in part, determined by the growth of young trees, we evaluated the responses of Pinus ponderosa seedlings to ambient or elevated CO2 and/or high O3. Shoot growth and whole plant biomass were evaluated for seedlings growing under the CO2 and O3 treatments for 3 years in sun-lit mesocosms with ambient temperature and humidity. This study indicated the potential for CO2 but not O3 effects on Pinus ponderosa seedlings under realistic field conditions as used in this study
