Changes of Potential Suitable Areas for Lynx Under Climate Change in Mohe Area, Daxing'anling Mountains, China

Wildlife Letters, EarlyView.
Climate change drives shifts in suitable habitats for Eurasian lynx and its prey (hare, roe deer) in Mohe, Daxing'anling Mountains. Under RCP scenarios, moderate warming (RCP4.5) promotes substantial habitat expansion, while high‐emission conditions (RCP8.5) lead to strong expansion in the 2050s but slower gains and partial contraction by the 2070s ...

Root exudates mediate microorganisms to improve rhizosphere nutrient availability and crop productivity under straw mulching and slow‐release nitrogen fertilizer

Functional Ecology, EarlyView.
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 ...

From pollen provision to pollinator: Species‐specific sterol assimilation by wild bees in urban landscapes

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Human‐driven landscape change, particularly urbanization, is reshaping pollinator communities, yet the functional traits that mediate species persistence remain poorly understood. Dietary specialization is commonly used to predict species vulnerability.

The role of jumping translocation breakpoint gene promoting instability of genome and the biological function of its protein and potential clinical value [PDF]

, 2014
染色体不稳定性是大多数肿瘤细胞特别是实体瘤细胞和体外转化细胞的基本特征。其表现形式包括整条染色体的获得或缺失，杂合缺失，染色体易位重排，基因扩增等。目前认为染色体不稳定是肿瘤形成的始发因素，出现在肿瘤进展的早期阶段。体内外各种损伤刺激导致的基因组DNA链的断裂是染色体不稳定的根本原因。我们的研究发现，跳跃易位断裂点基因（JTB）在胃癌、肝癌中存在广泛的基因扩增和基因易位行为，而基因的扩增和易位是DNA双链断裂后异常修复的最终结果。JTB基因的断裂易位将导致其编码跨膜结构域的基因序列丢失 ...

Rapid construction of insect–plant interaction networks via multiplexed long‐fragment DNA metabarcoding and NGS

Methods in Ecology and Evolution, EarlyView.
Abstract Molecular identification of insect food webs can accurately reveal complex trophic interactions and serve as a foundation for understanding ecosystem functioning and advancing biodiversity conservation. This process typically involves DNA library construction, high‐throughput sequencing and subsequent steps, including data assembly, annotation,

Functional analysis of Hedgehog gene in amphioxus embryogenesis and mutants construction related to the Hedgehog signaling pathway [PDF]

, 2015
Hedgehog（Hh）基因在动物胚胎发育过程中有着重要的作用，该基因最早在果蝇中发现，参与果蝇分节极性（segmentpolarity）的形成及翅原基前后组织中心的建立；在海胆中，参与中胚层的分化；而在脊椎动物中，该基因主要参与中枢神经系统（CNS）、轴旁中胚层及附肢的发育。在头索动物文昌鱼中，前人基于Hh的表达谱分析，推测该基因参与神经管的发育及左右轴的建立，提出Hh对神经管腹侧神经元分化的作用可能是一原始特征。 本文用基因敲低、过表达和敲除3种方法对文昌鱼Hh基因在胚胎发育中的功能做了进一步研究 ...

Global overview of progress in respecting the contributions of traditional knowledge in biodiversity governance

Conservation Biology, EarlyView.
Abstract Recognition and engagement of Indigenous Peoples and local communities (IP&LCs) and other traditional knowledge (TK) holders in formal biodiversity governance remain limited, despite their significant contribution to the conservation and sustainable use of biodiversity through their knowledge, innovations, practices, and land stewardship.
