2015年7月14日 评论已被关闭

2014年12月28日,李志鹏同学完成了他的硕士开题报告,报告题为“小尺度热带季节雨林线虫空间格局驱动机制”,他的实验在补蚌大样地建立1公顷调查样方,通过高密度采样调查线虫群落与土壤养分、地形及植物的空间关联,从而研究生态位过程及中性过程在土壤生物多样性形成与维持中的作用。
同日,胡鸿雁同学完成了硕士中期报告,她做了题为“片段化热带森林的叶虫食及其影响因素研究”的报告。实验在纳板河自然保护区内8个热带森林片段内进行,旱季调查的9种树种中只有假海桐和短刺栲在大小片段内的虫食率有显著差异,其他树种差异并不显著,表明植物的叶虫食格局对不同尺度片段化森林的响应存在种间差异性。对叶虫食格局造成影响的因素还有待于进一步研究。
同时,硕士研究生王瑾同学做了题为“热带森林生境片段化对土壤动物群落结构的影响”的中期报告,其研究了纳版河流域热带雨林和常绿阔叶林森林片段化对土壤动物群落结构和分布的影响,展示了其阶段性成果:片段化森林中土壤节肢动物总体丰度和多度雨季显著高于旱季,季节变化对热带雨林小片段生境中的动物有极显著的影响。连续森林土壤节肢动物总体多度和丰度显著高于片段化森林,在大小片段森林之间,仅有动物总体丰度和蜱螨目密度有显著差异,并且大片段显著低于小片段森林。评审老师针对三位同学的答辩内容和数据分析提出了很好的建议。

December 2, 2014. Liu Shengjie, who is a student in soil ecology group, successfully defends his theses. Liu Shengjie made a report entitled “Spider cascading effect in the forest floor and tea garden ecosystem”. His findings show that spiders, as predators, can more effectively control the number of prey populations, resulting in a cascading effect and then affecting ecosystems ecological processes in both the tropical forest floor detritus food web and tea garden ecosystem. However, several factors such as spider predation strategy, density, and environmental conditions will affect the intensity of cascading effect.
We are all very proud of you and wish you much success in your future academic careers. Addition, we have to say thank you to the examination committee for taking the time to review his theses.

December 2, Professor Liu Manqiang, who works in Soil Ecology Laboratory of Resources and Environment Institute of Nanjing Agricultural University, was invited to visit XTBG by Professor Yang Xiaodong.
During the visit, Professor Liu Manqiang made a wonderful report with the title ‘Exploring the roles of soil community characteristics in delivering soil ecosystem functions’. The report describes their recent two sophisticated research work: the invasion of alien microbes and herbivory affect underground nematode community, and moreover he exploreed the relationship between soil biological communities and ecosystem function. After the meeting, Professor Liu also conducted extensive exchanges and discussions with the scientists.
Professor Liu Manqiang is one of the few nematode ecological experts in china, his report have a good inspiration for our future research in ecology of soil nematode.

Xiao haifeng and Li zhipeng attend Soil Ecology Training Workshop in Nanjing Agricultural University

2015年7月14日 评论已被关闭

Over the past decade, China’s ecological problems have become increasingly prominent, research on soil ecology continues to expand the breadth and depth in china, and systematic research has also been enhanced. More and more Young scholars began to study soil ecology. However, they faced varies difficulties and need to know about the basic knowledge and research methods. In view of this, the soil ecological research group of Nanjing Agricultural University invited Professor Sina Adl who works at the University of Saskatchewan, Canada to teach in China. Professor Sina Adl has very high international reputation in the field of protozoa classification research.
Xiao Haifeng and Li Zhipeng attended this training workshop. This training workshop reinforced our understanding of soil ecology. Particularly, Professor Sina Adl introduced a variety of new technologies application in the field of soil ecology, which gave us a deep impression. This training workshop helps us a lot for our future research.

Pro. Yang was invited to attend the conference of The National Biodiversity Conservation Science

2015年7月14日 评论已被关闭

Biodiversity conservation and related research work has received worldwide concern and attention. As the world’s one of the most biologically diverse countries, China has made ​​significant progress in this field. August 16, 2014, The National Biodiversity Conservation Science conference was held in Shenyang. This conference was founded in 1994, and held once every two years thereafter, which is representing the highest level of research in the field of biodiversity. The main purpose of the conference is to promote biodiversity conservation and exchange of academic research.

Pro. Yang XD, who is the PI of Soil Ecology Group of Xishuangbanna Tropical Botanical Garden, Chinese Academy of Sciences, was invited to attend this conference. Pro.Yang made a report entitled ‘Tropical, subtropical evergreen broadleaf forest soil animal community role in the decomposition process and its response to elevation gradient’ at the conference, which caused great interest of participants and was highly evaluated by peers.
