Sino-Russian cooperation on the sustainable utilization of Arctic biological resources: modernizing traditional knowledge

Considering the effects of global warming,humans need to face the possibility of an ice-free Arctic during summer.Russia spans Eurasia and occupies more Arctic lands than any other country.This vast area has a great variety of species,and the geography and environment of the Arctic have endowed these species with unique and valuable properties.All the world’s ancient nations have their traditional knowledge.The indigenous traditional knowledge of the Arctic and the knowledge embedded in traditional Chinese medicine are part of the world’s time-honored wisdom.Some of this ancient lore cannot be verified by modern scientific methods,but the methods are effective in practice,triggering further exploration and innovation.Russian Arctic indigenous people have a long history of using the Arctic biological resources.The use of therapeutic materials in traditional Chinese medicine has many similarities with the use of Arctic biological resources by indigenous peoples.Both types of traditional knowledge can inspire new approaches to the development of the Arctic biological resources.China and Russia are among the world’s largest countries,and it is important that they cooperate in developing the Arctic biological resources.The development of sustainable use of these resources,while updating traditional knowledge,is an urgently needed investment that requires an innovative approach.

Comparison of biological characteristics of marrow mesenchymal stem cells in hepatitis B patients and normal adults

AIM: To establish a culture system of marrow mesenchymal stem cells (MSCs)from hepatitis B patients and normal adults and to compare their biological characteristics. METHODS: MSCs were isolated from bone marrow in 34 male hepatitis B patients and 15 male normal adults and cultivated in vitro. Their biological characteristics including surface markers, shapes and appearances, growth curves, first passage time and passage generations were compared. RESULTS: Cultivation achievement ratio of hepatitis B patients was lower than that of normal adults, no statistical significance (82.35% vs 100%, P > 0.05). Compared with MSCs of normal adults, MSCs of hepatitis B patients presented a statistical lower growth curve, longer first passage time (13.0 ± 1.6 d vs 11.4 ± 1.5 d, P < 0.05), fewer passaging generation numbers (10.5 ± 1.4 generations vs 12.3 ± 1.7 generations, P < 0.05), though both shared same appearances, shapes and surface markers. MSCs in hepatitis B patients would expand, spread out and age more easily and there were more refractive particles in the cytoplasm. CONCLUSION: MSCs from hepatitis B patients can be cultured in vitro. Although their appearance, shape and surface marker are similar to those of MSCs from normal adults, there are differences in their biological characteristics.

The Core Mechanism of Natural Selection: How the Natural Cycle of Potassium Resources Affects the Biological Evolution and the Change of Human Society

Darwin’s theory of evolution believes that biological evolution is a process of natural selection. This theory has been supported by much evidence, but the internal biological mechanism is not clear. Here, I elaborate on the cycle of potassium resources on the earth and the biological utilization and efficiency, which may be the core mechanism of natural selection and affect the evolution of organisms and the development of human society.

The history and future of the biological resources of the Caspian and the Aral Seas

The term ‘biological resources' here means a set of organisms that can be used by man directly or indirectly for consumption. They are involved in economic activities and represent an important part of a country's raw material potential. Many other organisms are also subject to rational use and protection. They can be associated with true resource species through interspecific relationships. The Caspian and Aral Seas are continental water bodies, giant saline lakes. Both categories of species are represented in the benthic and pelagic communities of the Caspian and Aral Seas and are involved in human economic activities. The most important biological resource of the Caspian Sea and the Aral Sea is their ichthyofauna, represented by both aboriginal species and species introduced by man in the 20 th century. Among invertebrates, the main biological resource of these saline lakes is the brine shrimp A rtemia. The physical state of the Caspian as a water body is relatively stable but its biological resources are very seriously af fected by irrational use. The Aral Sea since the second half of the 20 t h century has experienced catastrophic anthropogenic regression, which has led to the almost complete loss of its biological resources due to salinization. However, thanks to efficacious engineering measures, it has now become possible to preserve its northern part(Small Aral) and rehabilitate it, lowering the salinity to its former state. The result has been the restoration of its fish biological resources. In the southern part of Aral(Large Aral), which turned into a group of separated hypersaline reservoirs, the only resource species currently available is the brine shrimp A rtemia. The main environmental threats for biological resources of the future Caspian and Aral as well as potential solutions are considered.

AN OBSERVATION STUDY ON BIOLOGICAL CHARACTERS AND MATING BEHAVIOR OF DAHURIAN CASEBEARER(COLEOPHORA DAHURICA FLKV.)ADULTS

Through rearing tests and observations under laboratory conditions, biological characters and mating behavior of Dahurian casebearer (Coleophora dahurica Flkv.) adults were studied in this paper. Results discovered that the time of emergense of male adults was 24h to 36h earlier than that of female adults. The peak of sex pheromone secretion of the female adults appeared of 24h to 42h after the emergence. The reaction of male adults on the sex pheromone was most sensitive during 30h to 48h after emerged, so the earlier emergence of the male adults was favorable to mating. The phenomenon of repeated mating did not exist in female adults, but the male adults could mate for several times, with maximum of 4 times. There was a definite behavioral reaction during the mating period of male and female adults, and the certain period of feeding and mating times could affect the adults longervity to a certain degree.

The Evaluation Criteria of Some Botanical Quantitative Characters of Peach Genetic Resources

There were two peach descriptors systems： one from IPRGI in 1980 and the other from China in 1990. The former had only reference cultivars without quantity grades; the latter had only a list of some eharacteristics. This makes it difficult sharing of genetic resource information for breeders. To describe the main quantitative characteristics, a new system was established. Ten characteristics of 346-476 peach cultivars were investigated from 1986 to 2002 in the National Peach Genetic Collection in Zhengzhou City, China. These characteristics and their coefficients of variation were as follows： flower diameter 19.55%, vertical diameter of fruit 14.24%, cheek diameter of fruit 10.36%, suture diameter of fruit 11.44%, stone length 19.04%, stone width 10.86%, stone thickness 11.19%, leaf length 7.9%, leaf width 10.55%, and leaf stalk length 19.03%, respectively. Grade index and reference cultivars were given by statistical data for peach description. These grade indexes were recorded on 1-5 grades, and the third grade as a middle one occupied 39% or more of the distribution. In general, two reference cultivars for each grade were chosen, one is USA cultivar and the other is Chinese cultivar. This paper tried to use them as the reference cultivars, which are planted or used widely by Chinese breeders.

Observation of Biological Character of Drosophila melanogaster Meigen on Cherry and Screening of Its Insecticides

Indoor rearing observation and efficacy test of insecticides were conducted in 2010 to understand the biochemical characteristics of Drosophila rnelano-gaster and high efficient insecticides against the insect pest. The results showed that D. melanogaster had preference to eight kinds of fruits with proliferation. Fe-male adults of D. melanogaster laid eggs under epidermis of cherry fruits and newly hatched larvae caused damage on fruits. When the temperatures were （ 18 ±2） ℃ and （ 23 ± 2 ） ℃, the egg stage was 2.4 - 3.0 and 1.2 - 1.8 d ; the larval stage was 11.2 - 12.2 and 5.6 - 6.5 d; the papal stage was 9.5 - 10.6 and 5.0 - 6.2 d ; one generation was 23.1 - 25.4 and 12.8 - 14.2 d, respectively. Four insecticides （ including 1% emamectin benzoate EC 3 000 times dilution, 90% crys- tal trichlorfon 1 000 times dilution, 40% phoxim EC 1 500 times dilution and 25% buprofezin WP 2 000 times dilution） had higher control effects against D. mela-nogaster, with mortalities of 85.00% - 100.00%, 96.67% - 100.00% and 100.00% after insecticide application for 1, 3 and 6 h, respectively.

An Inventory of the Geological, Biological and Cultural Resources on Ufe-Oke Hill, Idanre, Southwestern Nigeria

Idanre, which represents a unique topographical landscape within southwestern Nigeria, is being proposed to the United Nations Educational Scientific and Cultural Organization (UNESCO) for designation as a world heritage site. In line with this, we conducted a survey to document the rich geological, biological and cultural resources contained within the Ufe-Oke section of Idanre Hills. Our geological inventory revealed two major rock types, older porphyritic granite and fine grained granite, in addition to other minerals. We identified insects belonging to 174 species while fishes from 4 species were collected. Mammals belonging to 13 species were identified through trapping, sightings and signs, although an even greater variety was inferred from interviews with hunters and visits to local fetish markets. Patterns concerning how these biological taxa are distributed altitudinally along Ufe-Oke Hill are discussed. In addition, in the quarters within Ufe-Oke representing the ancient city of Idanre, we characterized about 200 pieces of anthropological material, which included pottery shards, beads, chinaware, brass bangles and ancient metal coins. We also identified various other major features of archeological interest. Finally we offer recommendations, in the light of our findings, concerning how the variety of resources catalogued in this study can be effectively harnessed while sus-taining at the same time the environmental integrity of this site, which offers the greatest opportunities and potential for tourism.
