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

open access: yesIntegrative 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.

Impacts of livestock grazing on blue‐eared pheasants (Crossoptilon auritum) survival in subalpine forests of Southwest China 散放家畜对中国西南山地亚高山森林雉类蓝马鸡的影响

open access: yesIntegrative 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

open access: yesConservation 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

Conserving urban tropical biodiversity by connecting networks of green patches 连通绿地斑块, 保护热带城市生物多样性 Memulihara biodiversiti tropika bandar dengan menghubungkan rangkaian tompok kawasan hijau

open access: yesIntegrative 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

open access: yesConservation 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.

丙烯酰胺对甲基丙烯酸-丙烯酸酯乳液型破乳剂的性能影响

open access: yesGongye 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。

冻融破乳方法对水代法提取油茶籽油的影响Effects of freeze-thaw demulsification methods on aqueous extraction of oil-tea camellia seed oil

open access: yesZhongguo youzhi, 2023
为提高水代法提取油茶籽油的提油率,将油茶籽经过脱壳、粉碎、过筛、加水过胶体磨、离心分离得到乳状液,经冻融破乳后离心分离得油茶籽油。以提油率为指标,探究了加热冻融、乙醇冻融、调pH冻融、加盐冻融等冻融破乳方法对水代法提取油茶籽油的影响,并通过共聚焦激光扫描显微镜对破乳前后乳状液的微观结构进行了观察。结果表明:乙醇冻融和加盐冻融使油茶籽的提油率降低;调pH可提高提油率,在pH为8时提油率为92.17%;加热冻融法是最佳的冻融破乳方法,在加热温度60 ℃、加热时间20 min条件下,提油率最高,达到92.57%

Applying habitat and population‐density models to land‐cover time series to inform IUCN Red List assessments

open access: yesConservation 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.
