Comprehensive framework for assessing and optimizing existing research networks
Conservation Biology, EarlyView.Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

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.

Guangxi Zhiwu水韭属是一类具有异形孢子的古老石松类植物，全属物种均被列入国家重点保护野生植物。该文报道了在浙江省长兴县新发现的一个四倍体水韭属居群。基于形态学、孢粉学和细胞学证据，将该物种命名为长兴水韭（Isoëtes changxingensis），并详细描述了其形态特征。长兴水韭与保东水韭（I. baodongii）在植株形态及孢子纹饰方面都较为相似，不同之处在于其染色体为44条，大孢子极面直径为317~411 μm（平均为360 μm）（vs.染色体22条，大孢子极面直径为390~510 μm，平均为450 ...

Taxonomic and functional diversity of urban bees of the world
Conservation Biology, EarlyView.Abstract Bees play a pivotal role in terrestrial environments. Urbanization can affect these organisms and the ecosystem services they provide. However, knowledge of the global diversity of urban bees is limited. Thus, we summarized data on urban bee species identities and occurrences; compared distributions of all bees with those found in urban ...

Estimating the total mortality of seabirds following a marine heat wave
Conservation Biology, EarlyView.Abstract Marine heat waves detrimentally affect a range of marine species, including seabirds, and are increasing in frequency and severity. When thousands of dead seabirds wash up on beaches, the public becomes concerned. However, the number of dead birds recorded on beaches is only a fraction of the total mortality; most birds perish at sea.

Emerging applications of large language models in ecology and conservation science
Conservation Biology, EarlyView.Abstract Large language models (LLMs) mark a major development in artificial intelligence, with potentially transformative implications for ecology and conservation science. Built on advanced deep‐learning architectures, these models can support a wide range of tasks. We reviewed emerging applications of LLMs, drawing on the wider scientific literature

Shuitu Baochi Xuebao, 2016 为保证桑树在三峡库区困难立地条件下的正常生长，对该区砾石土、粗骨土、砾质土和扰动土4种生境土壤结构稳定性与持水性能进行诊断，并探讨了各种生境障碍因素的改良途径。结果表明：（1）不同生境土壤物理性质差异显著（p＜0.05），土壤容重表现为粗骨土生境(1.30 g/cm3)＞砾石土生境(1.23 g/cm3)＞砾质土生境(1.12 g/cm3)＞扰动土生境(1.08 g/cm3)，砂粒含量为粗骨土生境＞砾石土生境＞砾质土生境＞扰动土生境。（2）不同生境土壤抵御季节性干旱能力差异较大，总库容表现为砾石土生境 ...

Jingshui jishu【目的】目前，我国已经形成了深度脱水-填埋、好氧发酵-土地利用、厌氧消化-土地利用、干化焚烧-建材利用这4条主流的市政污泥处理处置工艺路线，每种工艺路线都有各自的优缺点和适用条件，但每种路线的碳排放水平尚不明确，致使碳排放难以作为工艺比选测算指标落地应用。【方法】根据联合国政府间气候变化专门委员会指南，采用排放因子法，在确定核算边界后，全面核算了污泥从污水处理厂外运直至最终消纳的全流程碳排放量，包括处理处置过程中因甲烷(CH 4)和一氧化二氮(N 2O ...

Evaluating the use of taxonomy in the IUCN Red List
Conservation Biology, EarlyView.Abstract Taxonomy defines the units that conservationists strive to preserve for future generations. However, the discovery of new species and the taxonomic revision of existing species affect conservation efforts. Despite the importance of taxonomy for a species’ conservation, there is currently no overview of how those leading species extinction risk

Potential harm of coastal sedimentary nutrient in inducing red tide(沿海沉积营养物质对引发赤潮的潜在影响)
Zhejiang Daxue xuebao. Lixue ban, 2004 从生物地球化学的角度阐述了引发赤潮的营养和环境控制因素，并在分析了赤潮藻的限制性营养元素（磷、氮、硅）和微量元素（铁、锰）环境地球化学行为的基础上，提出了沿海沉积营养元素的释放与赤潮之间的相关关系模式，同时指出了中国沿海近代沉积物中营养物的积累趋势及其对引发赤潮的潜在危害，这不仅为揭示赤潮发生机理开辟了新的研究方向，而且也为有效地防治赤潮危害提供了科学依据.
