Perceived costs as drivers of wildlife management preferences in rural Tanzanian communities
Conservation Biology, EarlyView.Abstract Effectively managing human–wildlife interactions is crucial for fostering coexistence on shared landscapes. Management options are most effective when aligned with the preferences of people directly affected by wildlife, yet little is known about how socioecological factors influence these preferences.

Gongye shui chuli, 2000 烧杯搅拌实验和混凝前后水样中有机污染物的GC/MS分析结果表明,焦化废水中有机污染物的混凝去除机理主要是络合沉降和絮体吸附。各有机污染物的去除率与其分子结构密切相关,易在氢氧化物絮体上吸附或具有络合基团且无空间位阻的有机污染物,易被混凝去除。

Drivers of bat researchers’ intent to adopt field hygiene practices
Conservation Biology, EarlyView.Abstract Infectious disease is a growing threat to wildlife, with zoonotic transmission most likely at the human–wildlife interface. One underappreciated activity at this interface is fieldwork with wild animals, but associated risks can be mitigated through field hygiene (FH) practices, such as using personal protective equipment and other appropriate

Structured machine learning modeling to support conservation of deep‐sea benthic biodiversity
Conservation Biology, EarlyView.Abstract Biodiversity monitoring programs need to deliver accurate, timely, and actionable predictions. To establish a predictive monitoring program for deep‐sea benthos of the Santos Basin, Brazil, we developed a two‐stage structured model that allowed comparison of biodiversity predictions obtained from environmental simulations (2M‐Sim).

Gongye shui chuli, 2007 通过TiO2光催化氧化法,在60min内降解AMP、ADP、ATP有机磷标准化合物、尿素和EDTA有机氮标准化合物,并与国标方法消化结果进行了对比。光催化氧化法消化自然水体中有机磷和有机氮的效果可以达到并超过国标方法;有机磷化合物被降解成PO43-,有机氮化合物先被氧化分解成NH4+,再进一步被氧化成NO3-,降解产物便于进行定量测定,并设计出在线分析装置,从而使光催化氧化法替代传统方法用于分析自然水体中的溶解有机磷(DOP)和溶解有机氮(DON)成为可能。

Evaluating synthetic substitutes to reduce illegal harvesting and support species recovery
Conservation Biology, EarlyView.Abstract Providing synthetic substitutes is a widely promoted strategy to shift consumer demand away from wildlife products derived from threatened species. Yet, there is little evidence on whether product substitution prevents illegal or unsustainable harvesting and contributes to the recovery of threatened populations.
