Domestic UNFCCC Kyoto Protocol Mechanisms Project Supply Coordination Through Tendering – Lessons from the New Zealand Experience

A United Nations Framework Convention on Climate Change (UNFCCC) Joint Implementation (JI) host country has to make sure that JI projects are additional to avoid extra costs to generate the reductions necessary to cover the deduction of Emission Reduction Units (ERUs) from the country’s Kyoto Protocol emissions budget. A tender of ERUs by the government allows to generate additional reductions beyond the ERUs issued if it thoroughly checks project additionality. The government of New Zealand is running a tender for JI projects under the title “Projects to Reduce Emissions” since 2003. In two rounds, 10 million ERUs have been awarded and several projects have already entered into contracts with European buyers. The ratio of ERUs awarded to reductions achieved was 0.8 in the second tender. However it remains to be seen whether the additionality test of this tender is sufficient to exclude clearly non-additional projects.

曲霉对水中重金属的吸附去除

利用2种曲霉A.sojae M146和A.oryzae M149的菌体，作为吸附剂对水中Pb^2＋和Cd^2 进行去除实验。结果表明，曲霉菌体的最佳培养时间为72h，吸附的最佳pH为5．5、温度为30℃、时间为1h。在最佳实验条件下，A.sojae M146对Pb^2 和Cd^2 的吸附率，分别为69．76％和72．28％；A.oryzae M149对Pb^2 和Cd^2 的吸附率，分别为60．64％和81．34％。使用稀碱溶液对曲霉菌体进行浸泡预处理后，可提高对重金属的吸附去除效果；而使用稀释、乙醇水溶液以及蒸馏水对菌体浸泡后，明显降低了重金属的去除效果。Na2CO3和EDTA溶液，可以有效地将重金属从曲霉体上解吸下来，从而达到重复利用菌体作为吸附剂的目的。

Hybridization between wheat (Triticum aestivum) and the wild species Aegilops geniculata and A. biuncialis under experimental field conditions

Hybridization between Aegilops geniculata, A. biuncialis and bread wheat Triticum aestivum has been evaluated during two seasons under simulated field conditions to estimate the field hybridization rate under Central Spain conditions. The mean frequencies of hybridization between A. biuncialis and A. geniculata with wheat were 0.34% and 0.31%, respectively. Data from 10 hybrid plants for each combination showed that hybrids can be partially fertile by backcrossing with wheat parent, with percent averages of 3.17 grains/spikelets for A. biuncialis × wheat hybrids and 2.87 grains/spikelets for A. geniculata × wheat hybrids. Self-pollination, although at very low rates, was also possible in hybrids. The potential risks associated with natural hybridization in the context of transgenic wheat cultivation are discussed.
