New Phytologist, Volume 247, Issue 3, Page 1117-1128, August 2025.Summary Environmental changes and their effects are among the most pressing topics of today's ecological research. Shrublands, although widespread across the globe, remain understudied in this respect. We conducted a global meta‐analysis of 81 shrubland sites subjected to experimental warming, shifts in precipitation (e.g.

牛山湖两种优势小型鱼类空间分布与沉水植被的关系! [PDF]
, 2012 运用8种网目规格的成套浮性刺网作为鱼类采样工具,于2005年夏季在长江中游浅水草型湖泊牛山湖进行鱼类定量采样,通过比较不同茂密程度黄丝草生境中的小型鱼类组成、数量和大小结构,探讨此类湖泊小型鱼类的空间分布特征及其与沉水植被的关系.采样期间共捕获13种1124尾鱼,依据其等级丰度和出现频次,和红鳍原!为该湖优势上层小型鱼类.在调查的沉水植物生物量范围内,鱼类物种丰富度和Shannon多样性指数与沉水植物生物量之间呈现倒抛物线关系;两种优势小型鱼类的种群丰度均与沉水植物生物量有着显著的线性正相关关系 ...

New Phytologist, Volume 247, Issue 2, Page 504-517, July 2025.Summary Repetitive DNA is a feature of all organisms, ranging from archaea and plants to humans. DNA repeats can be seen both in coding and in noncoding regions of the genome. Due to the recurring nature of the sequences, simple DNA repeats tend to be more prone to errors during replication and repair, resulting in variability in their unit length ...

Actinobacterial Diversity in Depositional Environment of the Southwest India Ocean Ridge and Polyphasic Taxonomy of Five Marine Actinobacteria [PDF]
, 2015 随着各类拮抗病原菌和顽固性病原菌的出现，以及人们对抗病毒、抗肿瘤等低毒性药物需求的增加，海洋微生物活性次生代谢产物已经成为全球创新药物新的增长点。放线菌是一类重要的药用微生物资源，一百多年来，陆生放线菌资源的研究和开发利用取得了极其辉煌的成就；但受资源获取的限制，目前人们对海洋放线菌的研究还未完全展开。本论文以西南印度洋中脊沉积环境采集的海洋生物样品为基础，对其中的放线菌进行分离方法、生物学特性和系统分类学研究，并结合克隆文库方法对其中放线菌的多样性进行研究；对于发现的新分类单元菌株 ...

New Phytologist, Volume 247, Issue 1, Page 144-159, July 2025.Summary Domesticated chickpea cultivars exhibit limited genetic diversity. This study evaluated the effects of chickpea domestication on phosphorus (P)‐use efficiency (PUE) under low‐P conditions, using a diverse Cicer collection, including wild species. Two wild Cicer species – 54 C. reticulatum accessions and 15 C. echinospermum accessions, and seven
