Shuitu Baochi Xuebao, 2005 分析了土壤容重和气阻对一维垂直积水入渗的入渗率、累积入渗量以及湿润锋的影响,并对入渗过程中土壤平均含水率增量进行了研究。容重和气阻均对入渗率、累积入渗量和湿润锋有明显的影响:容重增加导致累积入渗量减少的减渗率在入渗过程中为一常数,相对于容重为1.3g/cm3土壤的累积入渗量,容重为1.4g/cm3和1.5g/cm3土壤的减渗率分别为31.79%和52.03%。容重增加导致湿润锋减少的减渗率在入渗过程中并非一常数,受到了入渗时间的影响;气阻导致累积入渗量和湿润锋减少的减渗率随基准入渗量的增加而变大 ...

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, 2021 通过开展不同流量（20，30，40，50，60 L/min）条件下的室内模拟细沟水流冲刷试验，研究不同容重（1.06，1.15，1.18，1.21 g/cm3）对喀斯特黄壤分离能力（Dc）的影响，并建立土壤分离能力预测经验模型。结果表明：流量与容重均显著影响土壤分离能力，当容重为1.06 g/cm3时，Dc随流量呈幂函数递增，而在其他更高的容重条件下，Dc随流量呈线性增加；同一流量条件下，Dc随容重增加呈线性减小，且减少趋势在高流量条件下更为明显；幂函数方程可分别描述Dc与水流剪切力（τ）、水流功率（ω）

Habitat and spatial trends of U.K. wintering waterbird populations over 50 years
Conservation Biology, EarlyView.Abstract The United Kingdom is an important wintering ground for millions of waterbirds. Most U.K. wintering waterbird populations increased between 1970 and the mid‐1990s, but declined thereafter. We examined U.K. population indices in 46 wintering waterbird species in two 25‐year periods, 1970–1994 and 1995–2019, to identify which waterbird groups ...

Changes in the transformative potential of action proposals in Finnish Red Lists from 1986 to 2019
Conservation Biology, EarlyView.Abstract Red lists provide critical knowledge regarding biodiversity decline, especially in Finland, where broad assessments have been made regularly since the 1980s. They deliver information on the threat status of species and ecosystems, propose actions to guide conservation policy, and have the potential to spur transformative change.

How identity bias affects perceptions of conservation messages on social media
Conservation Biology, EarlyView.Abstract Public support is essential for conservation, as public opinion can influence decision‐making and policy. Therefore, understanding whether bias toward conservationists due to their identity (identity bias) affects their perceived credibility and support for their recommendations is important.

Institutional lessons from the Nordic management model
Conservation Biology, EarlyView.Abstract To improve wildlife management outcomes, in terms of reaching management goals and increasing legitimacy, Nordic countries have developed institutional systems involving stakeholders that aim for a more inclusive and participatory model.

Shuitu Baochi Xuebao, 2019 为研究红壤地区土壤容重对涌泉根灌水分入渗能力的影响，以江西红壤为例，采用室内试验，研究了不同容重条件下红壤涌泉根灌水分运移及其分布特性。结果表明：容重对土壤入渗能力有显著影响。随着容重的减小，湿润锋、累积入渗量、入渗率均呈增大趋势，且容重越小，减小的幅度越大。湿润锋、累积入渗量以及稳渗率与土壤容重均呈幂函数负相关关系；对于同一深度土层，土壤容重越大，对应的土壤含水率越小，在水分再分布过程中容重对含水率分布的影响逐渐减弱。通过Kostiakov入渗模型表明，土壤初始入渗速率随容重增大而减小，且容重越大 ...

Shuitu Baochi Xuebao, 2021 为了探明冻融过程对东北典型黑土耕层氮（N）生物有效性的影响，试验利用室内模拟方法，探究了不同冻结温度、土壤容重、含水量、冻融循环次数影响下耕层土壤剖面速效氮（AN）的时空分布规律。结果表明，经冻融循环后，土壤AN含量随土层深度增加呈现波动性下降；冻结温度越低，AN随土层深度增加下降的波动性越大，AN峰值、AN土柱平均值越低；冻结温度-15℃时整个土柱AN平均值比-10℃降低9.3%~44.6%；容重增高，AN含量降低，AN/TN值升高，土壤容重1.1 g/cm3时整个土柱AN平均值比容重1.0 g ...
