1自然保护区、恢复力和动态景观显示文摘在这个日益被人类活动所改变的世界里,保护生物多样性对于维持有恢复力的生态系统和确保生态系统产品的可持续流动以及对社会的服务是至关重要的。但是,现有的自然保护区和国家公园不大可能结合生态系统的长期和大尺度的动态。因此,保护策略必须包括大面积的人类利用经营的土地。为了能使生态系统在大规模的自然和人为干扰之后得以重组,以生态存储形式出现的空间恢复力是必备的前提。生态存储包括那些能使生态系统得以重组的物种、相互作用和结构,它的组成部分可能出现在干扰斑块中,也可能出现在周围的景观中。现有的静态自然保护区应该由动态自然保护区加以补充,例如生态休闲地和动态演替保护区,这些都是在景观尺度上模拟自然干扰状况,进行生态系统经营的组成部分。Janne Bengtsson Per Angelstam Thomas Elmqvist Urban Emanuelsson Carl Folke Margareta Ihse Fredrik Moberg Magnus Nystrm 王胜 2003AMBIO-人类环境杂志2003,32,6:11
2大堡礁和大峡谷世界遗产区的适应性管理显示文摘关于人类和环境相互关系的传统观念正在迅速改变。那种认为人类与自然是相互隔离的,自然资源是取之不尽用之不竭的,而且认为世界是稳定的、可以预测的并且是平衡的旧观点已经过时了。在动态的社会-生态景观中强调学习和灵活性管理为基础的适应性方法的新的理念框架已经迅速初现端倪。我们以两个典型的世界遗产地区(大堡礁和大峡谷)为案例来研究如何在自然资源管理中通过改善科学和社会两个方面的结合来指导多尺度管理系统的变革从而应对和处理人类越来越占据主导的世界中出现的不确定性、风险和变化。Terence P.Hughes Lance H.Gunderson Carl Folke Andrew H.Baird David Bellwood Fikret Berkes Beatrice Crona Ariella Helfgott Heather Leslie Jon Norberg Magnus Nystrm Per Olsson Henrik sterblom Marten Scheffer Heidi Schuttenberg Robert S.Steneck Maria Teng Max Troell Brian Walker James Wilson Boris Worm 丁莉 2007AMBIO-人类环境杂志2007,36,B11:4

4Glutamate triggers the expression of functional ionotropic and metabotropic glutamate receptors in mast cells显示文摘Mast cells are emerging as players in the communication between peripheral nerve endings and cells of the immune system.However,it is not clear the mechanism by which mast cells communicate with peripheral nerves.We previously found that mast cells located within healing tendons can express glutamate receptors,raising the possibility that mast cells may be sensitive to glutamate signaling.To evaluate this hypothesis,we stimulated primary mast cells with glutamate and showed that glutamate induced the profound upregulation of a panel of glutamate receptors of both the ionotropic type(NMDAR1,NMDAR2A,and NMDAR2B)and the metabotropic type(mGluR2 and mGluR7)at both the mRNA and protein levels.The binding of glutamate to glutamate receptors on the mast cell surface was confirmed.Further,glutamate had extensive effects on gene expression in the mast cells,including the upregulation of proinflammatory components such as IL-6 and CCL2.Glutamate also induced the upregulation of transcription factors,including Egr2,Egr3 and,in particular,FosB.The extensive induction of FosB was confirmed by immunofluorescence assessment.Glutamate receptor antagonists abrogated the responses of the mast cells to glutamate,supporting the supposition of a functional glutamate–glutamate receptor axis in mast cells.Finally,we provide in vivo evidence supporting a functional glutamate–glutamate receptor axis in the mast cells of injured tendons.Together,these findings establish glutamate as an effector of mast cell function,thereby introducing a novel principle for how cells in the immune system can communicate with nerve cells.Md Abdul Alim Mirjana Grujic Paul W.Ackerman Per Kristiansson Pernilla Eliasson Magnus Peterson Gunnar Pejler 2021Cellular & Molecular Immunology2021,18,10:2

13Taxonomy of the White-browed Shortwing(Brachypteryx montana)complex on mainland Asia and Taiwan:an integrative approach supports recognition of three instead of one species显示文摘Background: The White-browed Shortwing(Brachypteryx montana) is widespread from the central Himalayas to the southeast Chinese mainland and the island of Taiwan, the Philippines and Indonesia. Multiple subspecies are recognised, and several of these have recently been suggested to be treated as separate species based on differences in morphology and songs.Methods: We here analyse plumage, morphometrics, songs, two mitochondrial and two nuclear markers, and geographical distributions of the two mainland Asian taxa B. m. cruralis and B. m. sinensis and the Taiwan Residents B. m. goodfellowi.Results: We conclude that these differ congruently in morphology, songs and DNA. Male B. m. goodfellowi is the most divergent in plumage(sexually monomorphic, unlike the two others; male similar to female), and B. m. cruralis and B. m. sinensis differ in male plumage maturation. The song of B. m. cruralis is strongly divergent from the others, whereas the songs of B. m. sinensis and B. m. goodfellowi are more similar to each other. Brachypteryx m. sinensis and B. m. goodfellowi are sisters, with an estimated divergence time 4.1 million years ago(mya; 95% highest posterior distribution [HPD] 2.8–5.5 mya), and B. m. cruralis separated from these two 5.8 mya(95% HPD 4.1–7.5 mya). We also report notable range extensions of B. m. sinensis as well as sympatry between this taxon and B. m. cruralis in Sichuan Province, China. Brachypteryx m. montana from Java is found to be more closely related to Lesser Shortwing(B. leucophris) and Rusty-bellied Shortwing(B. hyperythra) than to the mainland Asian and Taiwan Residents taxa.Conclusion: Our data support a recent proposal to treat the three mainland Asian and Taiwan Residents taxa as three species, separate from B. montana sensu stricto: B. cruralis(central Himalayas to south central China and south Vietnam), B. sinensis(north central to southeastern part of China's Mainland) and B. goodfellowi(Taiwan Island).Per Alstrom Pamela C.Rasmussen Canwei Xia Magnus Gelang Yang Liu Guoling Chen Min Zhao Yan Hao Chao Zhao Jian Zhao Chengte Yao James A.Eaton Robert Hutchinson Fumin Lei Urban Olsson 2018Avian Research2018,9,4:1
