Risks of concealing environmental degradation
Conservation Biology, Volume 40, Issue 5, October 2026.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 ...

Scientists’ warning on the global destruction of rock outcrop ecosystems
Conservation Biology, Volume 40, Issue 5, October 2026.Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...

Gongye shui chuli, 2013 采用AB法处理某饮料企业废水,通过对A段回流污泥采用强制曝气充氧使微生物处于内源代谢期,增强微生物的生物活性和吸附能力,提高A段有机物的去除率,使得企业即使在进水COD达到1 000 mg/L情况下亦能达标排放。工程调试运行结果良好,A段回流污泥强化再生后COD的去除率能达到70%以上,B段出水COD平均72 mg/L,完全满足设计要求。同时,污泥的强化再生为系统的安全可靠运行提供了重要保障。

Psychometric framework for coexistence with large carnivores
Conservation Biology, Volume 40, Issue 5, October 2026.Abstract Human–carnivore coexistence is essential for biodiversity conservation, yet measuring the attitudes and behaviors that support it remains methodologically challenging. We developed psychometric scales to assess willingness to coexist with carnivores and the underlying beliefs of this coexistence through an iterative expert elicitation process ...

西南岩溶区土壤微生物生态作用的初步研究--以桂林丫吉村岩溶试验场为例
Shuitu Baochi Xuebao, 2004 对桂林丫吉村岩溶试验场不同岩溶地貌的土壤微生物生理群的分布特征及土壤生物活性强度进行了研究，结果表明土壤生物活性强度的变化与土壤微生物数量的变化趋势基本一致。同时讨论了土壤微生物数量与土壤有机质、全N、有效N和速效P的相关性及微生物生理群在该场区氮循环中的生态作用。

Behavioral interventions to reduce demand for threatened freshwater turtles as pets
Conservation Biology, Volume 40, Issue 5, October 2026.Abstract Growing demand for freshwater turtles as pets has fueled illegal trade and accelerated wild population declines, underscoring the need for theory‐based demand‐reduction interventions. We conducted a three‐part randomized controlled trial with active turtle keepers (n = 1800) in China to test conservation‐ and legality‐framed messages by ...
