Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Permafrost thaw is reshaping nutrient dynamics in boreal forests, but its impacts on tree nutrient limitation and functional strategies remain poorly understood. Clarifying these responses is crucial for predicting the response of boreal forests to climate change.

Journal of Animal Ecology, EarlyView.This population‐comparative study reveals that male and female parents respond differently to social and ecological conditions. This sex‐specific responsive strategy is related to the incongruent parental care systems across populations in Chinese penduline tits.

Zhongguo shiyan zhenduanxue, 2011 癌基因的活化（如ras基因、bcr-abl基因）或/和抑癌基因的失活（如P53基因、Rb基因）与肿瘤的发生密切相关。ID4基因是1994年Riechmann等首次从小鼠中分离鉴定的,发现该基因在胚胎发育的9.5d-13.5d是上调的,且在成人的脑、睾丸和肾脏器官高表达[1]。

Inferring alternative ecosystem states with field survey data
Methods in Ecology and Evolution, EarlyView.Abstract Many ecosystems potentially exhibit alternative stable states, where distinct states can coexist under identical environmental conditions. While simulation models have generated key hypotheses in alternative stable states theory, they often rely on scale‐free parameters disconnected from real ecosystems.

膀胱移行细胞癌组织基因的P14ARF、DAPK、RARβ甲基化变异分析
Zhongguo shiyan zhenduanxue, 2012 目的通过检测新鲜冰冻膀胱癌组织中P14ARF、DAPK、RARβ基因的启动子CpG岛基因的甲基化状态,探讨P14ARF、DAPK、RARβ在膀胱癌发生过程中的作用及诊断意义。方法采用甲基化特异性PCR技术检测48例手术切除的膀胱癌组织和其中13例相应癌旁组织标本、17例非肿瘤患者正常膀胱组织中DAPK、RARβ、P14ARF基因的甲基化情况。结果 48例膀胱癌组织中发现P14ARF基因异常甲基化13例（27.0%）,DAPK基因异常甲基化13例（27.0%）;RARβ基因异常甲基化44例（91.6 ...

Drivers of bat researchers’ intent to adopt field hygiene practices
Conservation Biology, EarlyView.Abstract Infectious disease is a growing threat to wildlife, with zoonotic transmission most likely at the human–wildlife interface. One underappreciated activity at this interface is fieldwork with wild animals, but associated risks can be mitigated through field hygiene (FH) practices, such as using personal protective equipment and other appropriate

Advancing conservation breeding programs for marine invertebrates
Conservation Biology, EarlyView.Abstract In the face of ecosystem change and biodiversity loss caused by climate change and other stressors, conservation breeding, or captive breeding, with the aim of reintroduction for wild population recovery, is an emerging tool for preventing species’ extinction and rehabilitating ecosystems.

, 2000 采用聚丙烯酰胺梯度凝胶电泳及特异性组织化学染色技术分析了鲤、鲫及其基因组叠加的不同组合个体的红细胞ＳＯＤ． ＥＳＴ和血红蛋白的电泳图谱。结果表明不同基因组组合及不同倍性的个体间存在由基因组差异导致的生化多态性，为不同倍性的鱼类的同工酶（ＳＯＤ）表达存在基因剂量效应提供了依据，证实了不同组合的ＳＯＤ亚基间有协同表达、累积作用。研究表明每个基因有其独特的调控机制，因而在杂种三倍体内三分之一的基因组亦能够表达产物。应用本研究的遗传学数据有益于构建基因组特异性品系 ...

Conservation Biology, EarlyView.Abstract Although significant biodiversity has been safeguarded by protected areas (PAs), biodiversity trends continue downward. Within the frameworks of the EU Biodiversity Strategy for 2030 and the new EU Restoration Regulation (2024), conserving critical biodiversity areas is essential.
