Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Bone restoration is often hindered by the spatiotemporal dysregulation of immune and regenerative signals. Conventional bio‐inert implants, providing only passive support, fail to modulate this microenvironment, leading to infections and poor healing.

Wildlife Letters, Volume 4, Issue 2, Page 94-101, June 2026.Although once abundant across its range, gray foxes (Urocyon cinereoargenteus) are purportedly declining. While range maps indicate that gray fox potentially occur throughout the central United States, contemporary distribution maps are needed. We developed a Habitat Suitability Model for six states, leveraging gray fox presence data in an ensemble ...

Functional Ecology, Volume 40, Issue 6, Page 1725-1739, June 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Root exudates play a key role as signals and nutrients in mediating plant–microbe communication. However, critical knowledge gaps remain regarding how root exudates mediate soil–microbe–plant interactions to regulate crop yield under long‐term straw mulching combined ...

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas
Conservation Biology, Volume 40, Issue 3, June 2026.Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.

Shuitu Baochi Xuebao, 2007 利用自然降雨影响下的农田为试验样地,分析了降雨前后土壤颗粒组成与养分含量的变化,探讨了流失泥沙颗粒组成与养分的变化特征。结果表明,在降雨后,西瓜地与油菜地表土颗粒组成呈现粘粒与粉粒含量减少,砂粒含量相对增加的趋势;土壤养分含量都有不同程度的下降,其中水解氮与速效磷下降的幅度很大,西瓜地与油菜地水解氮降雨后降幅分别为9.67%和7.99%,速效磷的降幅分别为9.20%和8.76%;全氮养分降幅很小,西瓜地与油菜地分别为2.17%和1.54%;流失泥沙细小颗粒含量与养分含量随时间基本都呈降低的变化趋势 ...

Conservation Biology, Volume 40, Issue 3, June 2026.Abstract Despite the crucial role of human impacts on biodiversity loss, many assessments of this loss focus on single metrics, such as species richness, and overlook the multidimensional effects of human activities. Because of its importance to ecosystem functioning, we investigated the functional diversity of medium‐ and large‐sized mammal ...

转突变型A53Tα-突触核蛋白基因的帕金森模型小鼠中脑的全基因组甲基化测序分析
Zhongshan Daxue xuebao. Yixue kexue ban, 2020 【目的】研究帕金森氏病（PD）致病基因SNCA在A53T位置突变后对转基因小鼠中脑多巴胺，神经元DNA甲基化修饰的影响。【方法】分别取转突变的人源α-突触核蛋白（hα-syn）即hA53Tα-syn基因小鼠和对照组小鼠的中脑组织，采用重亚硫酸盐测序法（BS-seq）分别对12月龄的转基因小鼠和非转基因（nTg）小鼠进行全基因组甲基化分析，随后筛选出差异甲基化区域（DMR）用于GO富集分析。【结果】通过对比分析，我们总计发现481个DMR，其中高甲基化与低甲基化DMR分别有257和224个 ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Atomically dispersed iron–nitrogen–carbon (Fe‐N‐C) catalysts have emerged as promising alternatives for oxygen reduction reaction (ORR) owing to their highly atomic utilization. However, maintaining both Fe atomic dispersion and dense Fe‐Nx sites (typically below 2 wt%) in Fe‐N‐C catalysts is still a key challenge.

Methods in Ecology and Evolution, Volume 17, Issue 4, Page 1143-1160, April 2026.Abstract DNA barcode‐based species identification has become pivotal in biodiversity research. Current barcoding‐based deep learning methods have advantages in species identification but exhibit significant limitations. By using COI barcoding alone, previous studies were unable to fully capture species identification features. Prior methods showed that
