Changes of Potential Suitable Areas for Lynx Under Climate Change in Mohe Area, Daxing'anling Mountains, China 气候变化下中国大兴安岭漠河地区猞猁潜在适宜区的变化

open access: yesWildlife Letters, EarlyView.
Climate change drives shifts in suitable habitats for Eurasian lynx and its prey (hare, roe deer) in Mohe, Daxing'anling Mountains. Under RCP scenarios, moderate warming (RCP4.5) promotes substantial habitat expansion, while high‐emission conditions (RCP8.5) lead to strong expansion in the 2050s but slower gains and partial contraction by the 2070s ...

Using Harvest Data to Assess Factors Influencing Regional Population Declines of Muskrats (Ondatra zibethicus) 利用捕获数据评估影响麝鼠 (Ondatra zibethicus) 区域种群数量下降的相关因素

open access: yesWildlife Letters, EarlyView.
Reported annual per‐capita harvest of muskrats (PCHM) decreased as wetland complexity (total number of wetland patches) decreased in 13 state and federal wetland areas in the Midwest, USA. Our results support the hypothesis that regional‐scale declines in the abundance of muskrats are likely associated with the losses to wetland habitats throughout the

Conflict Social Networks of Critically Endangered Alpine Musk Deer in Captivity and Relationships With Fecal Steroid Hormones 圈养极危物种马麝的冲突社交网络及其与粪便类固醇激素的关联

open access: yesWildlife Letters, EarlyView.
We conducted a grouping study on 52 adult musk deer to investigate whether group sex composition modulates aggressive behavior and stress response in captive musk deer. We found that the conflict interactions of all‐male groups were significantly more than those of mixed groups, and compared with the mixed groups, the conflict interactions of all‐male ...

Updates on Breeding Success and Conservation Challenges for White‐Rumped Vulture (Gyps bengalensis) in Rampur Valley, Nepal 尼泊尔兰普尔山谷白腰兀鹫繁殖成功研究进展及其保护挑战

open access: yesWildlife Letters, EarlyView.
This study investigates the breeding success of the critically endangered White‐rumped Vulture in Khaireni Community Forest, and examines local knowledge and perceptions toward its conservation. We found that 71% of active nests were successful, with breeding success significantly influenced by the proximity to carcass deposition sites.

Acoustic Mimicry of Begging Calls and Its Geographical Differentiation in Nestling Common Cuckoos Toward Oriental Reed Warblers 大杜鹃雏鸟对东方大苇莺乞食鸣叫声的声学模仿及其地理分化

open access: yesWildlife Letters, EarlyView.
Common cuckoo nestlings from different populations show varying degrees of mimicry of warbler begging calls, with the Yongnianwa population being the most accurate and the Zhalong population the least. Overall, these cuckoos employ a dual strategy: they conservatively mimic the high‐frequency components of host calls while adaptively adjusting their ...

Plant invasion in mountain ecosystems reduces soil micro‐food web complexity at higher elevations

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Anthropogenic activities have accelerated plant invasions in mountain ecosystems, impacting the structure and functions of native plant communities. Changes in above‐ground vegetation can drive shifts in below‐ground biota, yet the effects of plant invasions on soil ...

多模态磁共振成像评估颈动脉粥样硬化易损斑块的应用进展(Research Progress on the Application of Multimodal Magnetic Resonance Imaging in the Assessment of Carotid Atherosclerotic Vulnerable Plaques)

open access: yesZhongguo cuzhong zazhi
颈动脉粥样硬化(carotid atherosclerosis,CAS)易损斑块是缺血性卒中的主要病因之一,其破裂与脱落在缺血性卒中的发生与发展中起着至关重要的作用。早期识别颈动脉狭窄程度和易损斑块成分特征,进行针对性防治,可改善患者预后。多模态MRI不仅能清晰显示CAS易损斑块的形态与大小,还可借助多参数成像技术评估斑块成分、炎症反应及血流动力学参数等,从而实现对斑块的全面评估。本综述通过回顾多模态MRI在CAS易损斑块评估中的应用进展,分析斑块特征对缺血性卒中的影响 ...

Herbivory enhances cadmium foraging in the invasive hyperaccumulating plant Phytolacca americana

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Biological invasions and heavy metal pollution are two pervasive environmental challenges threatening global ecosystems. While the elemental defence hypothesis posits that certain plants accumulate heavy metals to deter herbivores, it remains unclear whether invasive ...
