Methanotrophs,organisms that obtain oxygen by oxidizing methane,are recognized as the only known biological sink for atmospheric CH_4,and forest soil methanotrophs play crucial roles in mitigating global *** succession patterns of methanotrophic communities and functions in Wudalianchi volcano forest soils could provide a basis for the study of evolutionary mechanisms between soil microorganisms,the environment,and carbon cycling of temperate forest ecosystems under climate *** this study,the characteristics and drivers of methanotrophic community structure and function of two volcanic soils at different stages of development are analyzed,including an old volcano and a new volcano,which most recently erupted 300 years and 17-19×10^(5)years ago,respectively,and a non-volcano hills as control,based on space for time substitution and Miseq sequencing and bioinformation *** results showed that CH_(4) fluxes were significantly higher in old-stage volcano forest soils than new-stage forest soils and non-volcano forest *** were significant differences in the community composition and diversity of soil methanotrophs from different volcano forest *** was the dominant genus in all soil ***,the relative abundance of Methylococcus,along with Clonothrix,Methyloglobulus,Methylomagum,Methylomonas and Methylosarcina,were the important genera responsible for the differences in methanotrophic community structure in different volcano forest *** relative abundance of methanotroph belonging toγ-proteobacteria was significantly higher than that belonging toα-proteobacteria(P<0.05).Chao1,Shannon and Simpson indices of soil methanotrophic community were significantly lower in new-stage volcanos and were significantly affected by bulk density,total porosity,p H,nitrate,dissolved organic carbon and dissolved organic *** were significant differences in community structure between new-stage and old-stage volcano

Ulomoides dermestoides （Chevrolat）（Coleop- tera： Tenebrionidae） is one of the most notorious pests in northeastern China. We examined microtrichia on the thorax, elytra and abdomen of U. dermestoides using scanning electron microscopy and recorded their confor- mations （size, shape and insertion method） and distribu- tions （length, width and location）. Possible functions of the microtrichia were （1） stridulation： microtrichia on the inner surface of the elytra interacted with microtrichia on the dorsoventral axis of the thorax or on the costal vein of the hind wing; （2） to increase friction： at the major surface on the middle of the abdominal tergum, hind-wings, inner surface of the medial edge of the elytra and the posterior end of the elytra; （3） protection： the microtrichia covering the posterior face of the abdomen conserved water in the body and protected the body from damage; and （4） sensing organ： the special shape of the microtrichia on the nerva- tion near the vannal fold of the hind wing, the anterio- metapleuron on the metathorax, and the posterior field of the abdomen could perceive the environment. In conclusion, the size and shape of the microtrichia are tightly related to their functions, which may have evolved with the beetles＇ lifestyle.

In this paper,the quantitative approach is applied on the study of coniferous forestbased on the data which were collected by the field investigation in Daxinganling *** mainpurpose is objectively to show the position of communities in the space and the relationship be-tween the community and *** means of ordination,it is found that dahurian larch for-est,mongolian scots pine forest and korean fir forest lie in different positions. Gradient analysis ofthree dominant types of conigerous forest has revealed the difference of ecological amplitude,thedifference is one of the important reasons that determine the different communities in the differentenvironment.

The pattern of nutrient cycling in a succession series from birch (Betula platyphylla) Stands to Korean pine (Pinus koraiensis) Stands was revealed by studying the extant amount and nutrient contents of litter,biomass of shrubs and herbs and so on. In this succession series,the litter and its mineral elements increased with the soccession deveoping, but the maximum was in birch stand rather than in Korean pine stand stage. With the age increased,the biomass of the shrubs and herbs decreased but the nutrient contents increased with; and the total biomass and its mineral elements of the shrubs and herbs showed fluctuation property.

Cornus stolonifera is a ornamental trce species which was introdced to China in 1982. During the period of ten-year cxperiment a complete and systematic study on its botanical features, biological charcteristics, growth rhythm and propagation tcchniques was carried out on basis of the comparison withthe native species Corms alba. The research results showed thatCornus stolonifera has many advantages over Cornus alba in those such as fast growing, cold endurance, drought resistance, easy *** and pest-resistance, beautiful tree form,bright colour branches, long florcscence, persistant fruits and intcgrate visual cffects. Practice has proved that it is reslly a fine species for tree-planting. Not only does it have the function of water conservation, but also its branches can be uscd as a fine wcaving matcrial. Up to the present,about ten thousand plant stocks have bcen planted by more than 30 units in l l cities of 6 provinces and it has been well recicved by people.
