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 ...

Use of carrion fly iDNA metabarcoding to monitor invasive and native mammals
Conservation Biology, Volume 37, Issue 5, October 2023., 2023 Abstract Severely fragmented habitats increase the risk of extirpation of native mammal populations through isolation, increased edge effects, and predation. Therefore, monitoring the movement of mammal populations through anthropogenically altered landscapes can inform conservation. We used metabarcoding of invertebrate‐derived DNA (iDNA) from carrion

Integrative Conservation, Volume 2, Issue 2, Page 80-94, June 2023., 2023 The objective of this study is to characterise ecological connectivity for mammals and identify important patches and linkages for connecting urban green spaces for Greater Kuala Lumpur, Malaysia. Our results demonstrate the potential for Southeast Asian megacities to support biodiversity in the urban context, and the potential for a different kind of ...

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.

Gongye shui chuli, 2023 采用乳液聚合的方法合成了含有不同丙烯酰胺（AM）投加量的甲基丙烯酸-丙烯酸酯乳液型破乳剂。为考察AM对破乳剂性能的影响，通过使用离心法测量了乳液的乳胶粒尺寸分布，结果表明，投加AM的乳液，其乳胶粒平均直径要更大；对破乳性能的考察实验结果表明，AM的引入可有效提高破乳剂的破乳速度，同时对破乳效果也有一定的提高。

, 2022 为探讨延时时间及炮孔间距对岩石基坑爆破破碎效果的影响规律,依托大连地铁五号线虎滩公园站,建立岩体二维数值计算模型,通过连续-非连续数值模拟方法(CDEM)中的JWL爆炸模型及断裂能模型,对岩石基坑开展了爆破过程的数值模拟,并通过应力、振动速度、平均破碎尺寸、极限破碎尺寸、大块率及系统破裂度等指标进行综合分析。结果显示:模型监测点处以拉应力破坏为主导,延时35ms时应力波叠加效果较好,引起的模型监测点峰值振速较小;随着延时的增大,岩石爆破效果逐渐变差,而当延时为25 ms时 ...

, 2023 针对工业中乳化废液的破乳除油需求与难题,首先分析了各类工业乳化废液的水质情况,然后探讨了近年来主流化学破乳剂的破乳机理,并讨论了机理间的协同作用。对近年来关注度较高的聚醚类破乳剂、星型/超支化破乳剂、天然破乳剂及其改性破乳剂和磁性纳米颗粒破乳剂的结构和性能特点进行了综述,并对不同类型的破乳剂的优缺点进行评价与总结。在此基础上,提出了各类破乳剂在研究及应用过程中存在的某些共性问题,如不具有普遍适用性、缺乏对实际乳化废液使用情况的精确分析测试、在研发与应用方面存在局限性。因此,为了提高破乳效能 ...

Conservation Biology, Volume 33, Issue 5, Page 1084-1093, October 2019., 2019 Abstract The IUCN (International Union for Conservation of Nature) Red List categories and criteria are the most widely used framework for assessing the relative extinction risk of species. The criteria are based on quantitative thresholds relating to the size, trends, and structure of species’ distributions and populations.

Priority areas for conservation of Old World vultures
Conservation Biology, Volume 33, Issue 5, Page 1056-1065, October 2019., 2019 Abstract The prosperity and well‐being of human societies relies on healthy ecosystems and the services they provide. However, the biodiversity crisis is undermining ecosystems services and functions. Vultures are among the most imperiled taxonomic groups on Earth, yet they have a fundamental ecosystem function.
