Representation of obligate groundwater‐dwelling copepod diversity in European protected areas

open access: yesConservation Biology, EarlyView.
Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.

Effects of political identity activation and inaccurate metaperceptions on attitudes toward wolves

open access: yesConservation Biology, EarlyView.
Abstract Polarization between groups can undermine durable conservation outcomes. Activating group identities (i.e., an individual's sense of self derived from membership in a group) can exacerbate differences, especially when people hold inaccurate perceptions of their peers and rivals.

Constructed value of information with iterative scoring and parametric uncertainty to identify management‐relevant research priorities for a declining raptor species

open access: yesConservation Biology, EarlyView.
Abstract Constructed value of information (CVoI) is an expert elicitation decision‐analytic tool used to prioritize sources of uncertainty based on their potential to improve decision outcomes if resolved. Despite increased application of CVoI, the robustness of CVoI prioritization of sources of uncertainty relative to differences in expert elicitation

Perceived costs as drivers of wildlife management preferences in rural Tanzanian communities

open access: yesConservation 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.

真实地形地貌对闪电定位系统的影响

open access: yesDianci bileiqi, 2018
为了研究真实地形地貌对雷电回击电磁场和闪电定位系统的影响,利用柱坐标系下二维时域有限差分(FDTD)算法研究了真实地形地貌中高低起伏的地表对雷电首次回击电磁场以及闪电定位系统的影响。模拟结果表明,起伏的地形会使地闪首次回击垂直电场峰值减小,波形上升沿时间增大。但当地表出现特殊的地形结构时,真实的地形会增强垂直电场的峰值。对于雷电首次回击的切向磁场而言,地形地貌的高低起伏会明显衰减切向磁场的峰值,波头向后滞移,到达峰值时间滞后。例如,当雷电电磁场波从模拟闪击点到达测站1时 ...
