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

Role of funders in embedding tests in conservation practice
Conservation Biology, EarlyView.Abstract Effective conservation practice requires decisions based on reliable and relevant evidence, but significant gaps in the evidence base exist. Incorporating well‐designed tests of the effectiveness of interventions for biodiversity in conservation projects is one of the best ways to scale up the rate of evidence generation.

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 ...

Risks of concealing environmental degradation
Conservation Biology, EarlyView.Abstract Current practice seeks to conceal the visual impact of land‐use change (i.e., development). Six percent of development impact assessments in Australia and 14% of the World Bank's assessments recommend visual impact mitigation. This mitigation results in, for example, vegetated buffer strips alongside cleared agricultural areas and earthen ...

Gongye shui chuli, 2006 介绍了一种新的制药废水处理方法--混凝强化生物处理技术。将少量的硫酸亚铁混凝剂与废水混凝后进入生物曝气池运行，混凝过程形成的沉淀颗粒既能支持微生物的生长，又能在其表面形成生物活性膜，成为污泥菌类理想的载体，从而强化了生物处理的去除效果。该方法所需投加混凝剂的质量浓度仅为50mg/L，处理后产生的污泥量少，且污泥的沉降性能好。与常规的生物处理法相比，具有处理负荷高、去除效果明显等优点。并从混凝作用、生物膜的形成、铁离子对微生物的电子传递及催化作用等方面探讨了混凝强化生物处理的作用机理。

Gongye shui chuli, 2023 综述了利用氨氧化共代谢强化去除药物类污染物的研究现状，介绍了相关的微生物及其功能性酶对不同目标污染物的转化能力与转化机理，并分析了一些重要的影响因素及相应的控制策略。结果表明，与生长代谢途径相比，氨氧化共代谢在去除高毒性或难降解药物类污染物时具有明显优势。在合适的范围内，多种药物的降解速率与氨氮负荷呈正相关；当氨氧化受到抑制时，多种药物的去除率出现了不同程度的下降。同时也有研究发现某些共代谢产物具有比母体化合物更强的生态毒性或持久性。在工程应用中，氨氧化共代谢对药物类污染物的降解能力受多种因素的影响 ...

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.
