Toxic effect of lead(Pb) pollution on Collembola in soils has seldom been studied in depth, which is especially true for growth responses since the juveniles are very small and numerous. A single species test was conducted using the collembolan Folsomia candida as the indicator species, and soil Pb pollution(at Pb concentrations of 0, 300, 600, 1 200, 2 400, and 4 800 mg kg^(-1)) was simulated by mixing Pb(NO_(3))_(2) with a natural unpolluted soil. Adult survival, reproduction, body length, and body Pb concentration were determined. Adult survival and reproduction started to decrease at soil Pb concentrations of 1 200 and 600 mg kg^(-1), respectively. Lead concentrations in adult and juvenile bodies increased with increasing Pb concentration in soil. The percentage and individual abundances based on body length analysis showed that the larger adults(2.1–2.6 mm, P bio-indicators of soil Pb pollution and possibly other types of soil pollution.

A review on the eco-geography of soil fauna in China

引用

Journal of Geographical Sciences 2010年第3期20卷 333-346页

作者： YIN Xiuqin SONG Bo DONG Weihua XIN Weidong WANG Yeqiao College of Urban and Environmental Sciences Northeast Normal University Changchun 130024 China College of Environment and Planning Henan University Kaifeng 475004 Henan China College of Urban and Environmental Sciences Changchun Normal University Changchun 130032 China Department of Natural Resources Science University of Rhode Island Kingston RI 02881 USA

This review summarizes main research findings in soil fauna eco-geography in China in the past 30 years. The subject areas and main results were overviewed including biodiversity and eco-geological distribution of soil fauna communities. Studies of ecological distributions of soil fauna and dynamic ranges in space from tropical, subtropical to temperate regions, and in categories from forest, grassland, desert, wetland, farmland to urban ecosystems, the responses and indications of soil fauna to soil environments. Effects of intensive disturbance such as fire, grazing, farming, fertilization on soil fauna include sensitive （e.g. nematode） and rare groups and community indexes. The functions of soil fauna were discussed including environmental construction, environmental purification, litter decomposition and elements cycling. Interactions between soil fauna and other biota in soil ecosystems and linking between aboveground and belowground diversity and the effects of global change on soil fauna community in China were also included. Finally, the authors pointed out common interests in soil fauna eco-geographical studies, which include application of molecule biology into soil fauna taxa; function and mechanism of soil fauna community diversity; interaction between aboveground and belowground ecosystems; effects of disturbance, pollution, biological invasion, and global change on soil fauna community and function. The review is to provide a scientific basis for promoting soil fauna eco-geographical studies in China.

Uptake of Ag, Co and Ni by the Organs of <i>Typha domingensis</i>(Pers.) Poir. ex Steud. in Lake Burullus and Their Potential Use As Contamination indicators

引用

Open Journal of Modern Hydrology 2012年第1期2卷 21-27页

作者： Ebrahem M. Eid Mohamed A. El-Sheikh Abdulrahman A. Alatar 不详

The concentrations of Ag, Co and Ni in the sediments and the different organs of Typha domingensis from Lake Burullus, Egypt, were investigated monthly from February to September 2010 to evaluate the aquatic environment quality of the lake and to test the suitability of these organs for bio-indicating of sediment metals. The sediment heavy metals were found to decrease in the order of Ni > Co > Ag. The sediment contents of Ag were about 45 times above the worldwide range. On the other hand, Co concentrations were below the reference ranges of United States and Chinese soils. The heavy metals bioaccumulation decreased according to the order of rhizome > root > leaf for Ag;and root > rhizome > leaf for Co and Ni. It was found also that, T. domingensis had no significant differences in heavy metals concentrations over time. The transfer factors of Ag, Co and Ni from sediment to below-ground organs were smaller than one. Co had the maximum transport from below-ground to above-ground organs, while Ag had the minimum. There was a significant linear correlation between the concentration of Ag in root of T. domingensis and that in sediment. This result suggested that T. domingensis can be regarded as bio-indicator for Ag pollution of Lake Burullus.

Some Quantitative and Qualitative Data onAquatic Insects of Shkodra＇s Lake Region

引用

Journal of Environmental Science and Engineering(A) 2012年第2期1卷 224-227页

作者： Lagej Ariana Striniqi Kastriot Misja Department of bio-Chemistry The University of Shkodra Luigj Gurakuqi Shkodra 4000 Albania Department of bio-Chemistry The University of Tirana Tirana 1000 Albania

Aquatic insects present a great diversity of species for a certain water ecosystem. Beside the fact they are important indicator for the protection of water quality, the studies related to them are very scarce. Water entomofauna consists of a whole species belonging to different orders and classes of insects. Odonata (dragonflies) are the most famous and have impressive images. Odonata, Hemiptera and Coloptera are indicators of aquatic environments. The diversity of Aquatic Insect in Shkodra"s Lake Region shows the purity level of Shkodra Lake. Our conclusion is that no matter how small the pollution of Shkodra Lake is, it should be continuously monitored.

Relationship between Arthropods in Forest Litter and Forest Health

Chinese Forestry Science and Technology 2012年第3期11卷 34-34页

作者： Guo Rui Wang Yiping Wu Hong School of Forestry and biotechnology Zhejiang A & F University

As an important part in forest ecosystems, the arthropod communities in the forest litter are closely related to forest *** on the ecological function,community structure and biology of the arthropods,we discuss the theoretical basis for the selection of particular groups of arthropods as bio-indicators in this paper,and suggest that the evenness and richness of Collembola(Collembolan), Coleoptera(Beetle) and Hymenoptera(Ant) can serve as forest health *** terms of the relationship between forest litter arthropods and forest health,we summarize the main groups of forest litter arthropods suitable as bio-indicators and their ecological functions in forest ecosystems,and subsequently introduce a simple and accurate new method for selecting forest health indicator species by comparing the frequencies of the various species in different *** method was tested with a real case using forest litter arthropods as a bio- indicator to evaluate rain forest ***,the problems in using forest litter arthropods to evaluate and monitor forest habitat health are discussed and the use of multiple bio-indicator species in order to establish a balanced index system is recommended.
