为掌握广东连南万山朝王国家石漠公园鸟类资源现状,并为该公园鸟类资源保护和“引鸟”工程规划提供科学依据,项目组于2020年7月至2021年9月采用样线法开展了4次公园鸟类野外调查工作。调查结果显示,该公园已记录鸟类14目43科135种,其中国家二级重点保护野生动物25种;留鸟81种,夏候鸟30种,冬候鸟19种,旅鸟5种;87种鸟类属东洋界物种,35种属古北界物种,13种属广布种。鸟类物种多样性分析表明,公园内夏季鸟类的Shannon-Weaver多样性指数最高,为3.545;春季最低,为3.297。Pielou均匀度指数春季最高,为0.809;夏季和秋季均为0.796。在鸟类的5种生境中,Shannon-Weaver多样性指数从高至低依次为:灌丛(3.686)、乔木林(3.567)、农田(3.102)、村落(2.385)、库塘(1.679)。建议公园管理部门通过加强野生动物保护宣传力度、推进本地的生态文明建设、加大生态环境改造力度、提升鸟类栖息地质量、加强鸟类监测规范生态旅游活动等措施提高公园鸟类的物种多样性。

开展机场及周边区域鸟情调查,是机场鸟击防范的一项基础工作。为掌握新建湖北荆州沙市机场净空区鸟情,2020年6月至2023年2月,采用样线法对该机场净空区鸟类群落物种多样性及其分布格局进行了系统调查,期间共记录到鸟类146种,隶属于17目48科,其中鹬科鸟类物种数最多,其次是鹭科鸟类。鸟类群落中留鸟最多为48种,其次为冬候鸟41种,再次为夏候鸟36种;鸟类的区系构成表现为,古北界物种为71种,东洋界物种为51种,广布种为24种。通过季节间鸟类群落物种多样性比较,显示秋季鸟类群落的多样性指数最高(3.044),春季最低(2.298)。通过生境间的鸟类群落物种多样性比较,显示乔木林鸟类群落的多样性指数最高(3.236),村落最低(1.696)。调查结果表明,荆州沙市机场净空区鸟类群落物种丰富度和多样性水平较高,秋季候鸟迁徙期和夏季鸟类繁殖期成为全年鸟类活动频繁季节,潜在鸟击风险高;乔木林和农田成为机场周边鸟类最适宜的栖息地,也是鸟类侵入机场内活动的最主要鸟源地。

Dear Editor,The human body operates optimally at a core temperature of 37 degrees *** at this temperature is essential for cellular and physiological functions(Cheshire,2016).However,infectious diseases,inflammation,injury,neoplasia,and elevated climate temperature can cause a regulated rise in body core temperature,i.e.,fever(Pasi-khova et al,2017).Indeed,an acute or chronic increase in temperature leads to detrimental effects on vasculature by altering a number of indices of vascular structure and function(DuBose et al.,1998).

Dear Editor,Stem cells,including pluripotent stem cells and adult stem cells,possess the remarkable capability of being able to selfrenew while at the same time having potential to differentiate into different cell lineages and functionally distinct cell *** embryonic stem cells(hESCs)can differentiate into all adult stem cell types,including human mesenchymal stem cells(hMSCs)and human neural stem cells(hNSCs),but can also give rise to all terminally differentiated cell types(wang et al.,2021a).Through the continuous replenishment of differentiated cells,stem cells support tissue homeostasis and respond to tissue *** the promising applications of stem cells in cell therapy and regenerative medicine,insights into molecular events underlying stem cell maintenance,self-renewal ability and pluripotency,continue to garner strong interest(Shan et al.,2021).Although metabolic pathways have been implicated in the reciprocal regulations of stem cell self-renewal and differentiation as well as organ homeostatic maintenance(Garcia-Prat et al.,2017),central aspects of how metabolic requirements differ and are regulated across the various types of human stem cells in our body remain enigmatic.
