Between conflict and coexistence: Wildlife in rubber‐dominated landscapes 冲突与共存之间:橡胶林主导景观中的野生动物
Integrative Conservation, Volume 2, Issue 4, Page 240-254, December 2023., 2023 Natural habitat loss forces some wildlife species to increasingly extend their habitats into farmlands. Rubber‐dominated landscapes surrounding protected areas have the potential to facilitate coexistence between people and some wildlife species if young plants are better protected and plantation management is made more wildlife‐friendly.

Integrative Conservation, Volume 2, Issue 4, Page 201-213, December 2023., 2023 Livestock disturbances decreased the area of suitable habitat of forest pheasants by 14.28% in 7 years. Livestock activities remarkably increased the nest failure rate (by 2.18 times) of forest pheasants. Abstract The degradation and fragmentation of natural habitats, driven largely by anthropogenic activities such as grazing, represent growing ...

Time‐lagged effects of habitat fragmentation on terrestrial mammals in Madagascar
Conservation Biology, Volume 36, Issue 5, October 2022., 2022 Abstract Biodiversity is severely threatened by habitat destruction. As a consequence of habitat destruction, the remaining habitat becomes more fragmented. This results in time‐lagged population extirpations in remaining fragments when these are too small to support populations in the long term.

Impacts of Human Development on Wildlife Use of Corridors in Botswana 人类开发对博茨瓦纳野生动物廊道利用的影响
Integrative Conservation, Volume 5, Issue 1, Page 164-171, March 2026.This study examined the effect of landscape‐scale human impact on wildlife in Botswana. We examined how species use wildlife corridors in two different human‐dominated landscapes. We identified differences in temporal overlap between wildlife and humans across both landscapes, which is fundamental to consider in both current and future conservation ...

, 1995 当入射激光的波长、辐照时间、平匀功率密度保持相同的条件下,改变激光的时-空结构会产生不同的破坏模式.在上述激光基本参数不变时,如何合理选择激光的时空分布,以便达到最佳的破坏效果,这是激光破坏机理研究中的反问题.该文利用非高其空间分布激光辐照黄铜薄片材料,产生一种特殊的破坏模式——反冲塞效应,并对此进行了较系统的实验与理论分析,激光破坏反问题的提出和初步探索 ...
