RETRACTED: The Growing Tide of Antiscience Sentiment: A Global Concern
World Medical &Health Policy, Volume 17, Issue 3, Page 529-537, September 2025.ABSTRACT The growing tide of antiscience sentiment represents a critical global challenge, with particularly visible manifestations in the United States. This viewpoint examines how the rejection of scientific consensus threatens academic institutions, public health, and technological progress worldwide.

New Phytologist, Volume 247, Issue 5, Page 2086-2097, September 2025.Summary The importance of marine angiosperms, or seagrasses, as foundation species for marine coastal ecosystems is in marked contrast to their low species number of only 70 described taxa. Seagrass species tend to have very similar overall morphologies dictated by hydrodynamic forces of the ocean environment.

“Semper supra”? Trump administration policy narratives and the creation of the space force
Review of Policy Research, Volume 42, Issue 5, Page 1157-1183, September 2025.Abstract In 2019, the Donald Trump administration rejected the draft Treaty on the Prevention of Placement of Weapons in Space (PPWT) in the UN Conference on Disarmament and instead created the Space Force, the first new US military service branch established in decades.

Functional Ecology, Volume 39, Issue 8, Page 2149-2169, August 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Plants assemble beneficial rhizosphere microbiomes through a ‘cry for help’ mechanism upon pathogen or insect herbivore attack. The arbuscular mycorrhizal fungi (AMF) can influence the composition of microbial communities in the plant rhizosphere. However, their impacts

Policy Studies Journal, Volume 53, Issue 3, Page 747-773, August 2025.Abstract We integrate the study of policy design and diffusion theoretically and empirically to advance each and raise novel research questions. We argue that policy dissemination is an important rationale in the design of model legislation and present a theory for how each of the five elements of design map onto the policy innovation attribute of ...

Shuitu Baochi Xuebao, 2008 采用田间小区试验研究了不同的断根和施肥措施对I-107杨树人工林根际养分、微生物数量及酶活性的影响。结果表明:相同处理的杨树林地根际土壤pH均低于非根际土壤,而有机质、速效氮、速效磷、速效钾、有效铜和有效锌的含量均高于非根际土壤;与其它处理相比,断根施肥处理的根际土和非根际土壤速效养分含量最高,差异达显著水平;与对照相比,断根施肥处理显著提高了林地土壤的脲酶、转化酶、过氧化氢酶、多酚氧化酶和过氧化物酶活性,而施肥未断根处理少量增加了此5种土壤酶活性,断根未施肥处理则降低了土壤酶的活性 ...

Shuitu Baochi Xuebao, 2006 运用盆栽模拟土壤渍水逆境试验，研究不同生育时期根际土壤渍水逆境对不同小麦品种N、P、K素吸收、运转和分配的影响。结果表明，根际土壤渍水逆境对不同小麦品种N、P、K素吸收的影响有异;不同生育时期根际土壤渍水逆境显著影响根系对N、P素的吸收、运转与分配，以孕穗期渍水逆境影响最大，其次为灌浆期和拔节期，而不同生育时期根际土壤渍水逆境对K素的吸收影响较小。孕穗期以前浈水逆境主要影响小麦根系对N，P，K案的吸收．对N、P、K素在小麦体内的运输和分配影响较小；灌浆期渍水逆境不仅影响根系对N、P、K素的吸收 ...

The Palestinians in a Transforming Middle East: Adapting or Stagnating
World Affairs, Volume 188, Issue 3, Fall 2025.ABSTRACT This article examines the profound stagnation and decline confronting the Palestinian national movement in the aftermath of the October 2023 war in Gaza. It argues that Palestinian political fragmentation has coincided with an evolving regional landscape that increasingly sidelines Palestinians. On the international stage, waning US engagement,

岷江上游山地森林/干旱河谷交错带不同植被恢复模式对根际土壤微生物量碳氮及固氮菌群落结构的影响
Shuitu Baochi Xuebao, 2011 以岷江上游山地森林/干旱河谷交错带5种植被恢复模式的根际与非根际土壤为研究对象,对土壤微生物生物量碳、氮和土壤固氮菌群落结构的影响进行了初步研究.结果表明,5种不同植被根际与非根际土壤的微生物生物量存在显著差异且根际土壤含量大于非根际土壤,依次为:青冈次生林＞灌木林＞刺槐林＞人工幼林＞针阔混交林;DGGE图谱显示,5种植被根际与非根际土壤固氮类群有一条明显的共有条带,其中刺槐林和灌木林的固氮菌多样性最高;多样性指数、群落丰富度分析表明,灌木根际土壤固氮菌的群落种群结构最丰富,其次为刺槐;聚类分析结果显示,
