Evaluating the impact of caribou habitat restoration on predator and prey movement
Conservation Biology, Volume 37, Issue 2, April 2023., 2023 Abstract Fragmentation of the boreal forest by linear features, including seismic lines, has destabilized predator–prey dynamics, resulting in the decline of woodland caribou (Rangifer tarandus caribou) populations. Restoration of human‐altered habitat has therefore been identified as a critical management tool for achieving self‐sustaining woodland ...

Journal of Traumatic Stress, Volume 36, Issue 1, Page 129-143, February 2023., 2023 Abstract During the Great East Japan Earthquake, many people experienced the loss of family and friends, among other traumatic events. This study sought to clarify the impact of the loss of significant close others on posttraumatic stress symptoms (PTSS), as well as the factors associated with PTSS, among individuals who experienced the loss of ...

Journal of Traumatic Stress, Volume 34, Issue 3, Page 512-525, June 2021., 2021 Abstract The 2011 Tohoku earthquake and tsunami in Japan was an extraordinarily stressful incident that caused harmful psychological reactions, such as posttraumatic stress disorder (PTSD), among affected individuals. However, a proportion of exposed individuals experienced posttraumatic growth (PTG), characterized by a noticeable degree of personal ...

, 2010 在前面我们知道了为什么可能运用加卸载响应比方法做地震预测，加卸载响应比方法不仅有坚实的理论基础，而且为实验室试验、数值计算以及过去的震例检测所证实。那么，在实际运用中，它真的有效吗？ 尹祥础课题组将它用于地震中期预测已经取得了较好的效果，他们成功地预测过一些国内的地震，还成功地预测过一些国外的地震(美国，日本，土耳其等)。下面来看一些用加卸载响应比LURR预报地震成功的实例。 中国大陆： 早在1980年代后期,尹祥础课题组就用加卸载响应比方法对中外逾百个震例,从有感地震的4级～8 ...

, 1998 我们在中科院力学所非线性连续介质力学开放实验室（ＬＮＭ）材料试验机（ＭＴＳ）上做了岩石压缩破坏的加卸载实验，得到了以应变为响应（即弹性常数的倒数为响应率）的加卸载响应比。实验结果与理论以及实际地震中的加卸载响应比相一致，即加卸载响应比在临近破坏前上升。故此 ...

Dizhen xuebao, 2020 首先基于有限断层破裂下的运动学震源模型，对比验证了三维谱元法对于近场地震动的模拟精度。 进而通过含盆地模型与不含盆地的一维水平成层模型的地震动强度之间和放大系数分布特征之间的对比，详细研究了直下型断层的破裂速度对盆地地震效应的影响。结果表明，盆地的存在会显著改变近断层地震动的分布特征，同时盆地内不同分量强地震动的分布特征变化较大。断层破裂速度对盆地地震效应影响显著，随破裂速度的增大盆地地震动强度逐渐增加，但不同分量上地震动强度的增加速率显著不同，受盆地效应的影响，放大系数表现出与强地震动不同的分布特征 ...
