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.

, 1983 众所周知,流化床中气体一颗粒的传递过程和反应过程,主要发生在分布板区。而浅层流化床正具备了分布板区的许多优点,它在涉及热过程的领域中,已经显示了广阔的应用前景。 为了考察浅层床中气体一颗粒间的传递特征,本文从气体一颗粒传热入手,采用热响应的实验技术,测定了气-固系浅流化床(L/D_T=0.045～0.17)内空气-海砂的表观传热系数,同时求算了相应的浓相区传热系数,并表述了传热系数随床深的变化趋势。从实用角度,本研究最终将表明,在较浅的颗粒床层中,能给出较大的传热速率但床层压降较小 ...

Effects of restoration practices on biodiversity in temperate and boreal forests
Conservation Biology, EarlyView.Abstract Several restoration practices are used to mitigate and compensate for the negative effects of large‐scale forestry on biodiversity in temperate and boreal forests. A comprehensive synthesis of the benefits of these practices across taxa is missing. We conducted a systematic review and meta‐analysis on this topic.

Conservation Biology, EarlyView.Abstract Ecological niche models (ENMs) are used to assess the abiotic preferences of species by linking their occurrences to the environmental conditions in which they live. We developed a fossil‐informed ENM framework that integrates mid‐Holocene and modern occurrences to test niche stability and reconstruct abiotic niche characteristics for four ...
