Urbanization and Seasonality Increase Introduced Plant Consumption by the World's Southernmost Parrot 城市化与季节性增加了全球最南端鹦鹉对引入植物的取食

open access: yesIntegrative Conservation, Volume 5, Issue 1, Page 86-103, March 2026.
Urbanization may alter bird foraging. Austral Parakeets (Enicognathus ferrugineus) in Patagonia rely on introduced plants in urban areas, especially in winter, despite preferring natives in the wild. This seasonal reliance on introduced species highlights urbanization trade‐offs and underscores the need to manage green areas with native plants to ...

森林流域界面水分传输规律研究述评

open access: yesShuitu Baochi Xuebao, 2002
探讨森林植被对水文过程物理机制的研究不可避免地要以森林生态系统为单元 ,以森林生态系统各个界面层次对水分传输和水量转换的影响为基础来进行 ,这也正是目前界面水文学研究的焦点问题。基于此 ,综合国内外界面水文学的大量文献 ,在垂直维上从水分在森林流域内林冠层、地被物层、土壤层各主要界面层间的水量转换和运行传输规律 ,在水平维上从界面产流理论及其研究动态等方面的研究进展进行了回顾与评述 ...

基于月水量平衡的天山中部天然云杉林森林生态系统蓄水功能研究

open access: yesShuitu Baochi Xuebao, 2011
以天山中部天然云杉林森林生态系统为研究对象,以250 hm2流域尺度为单元,采用流域试验和水量平衡样地相结合的方法,对森林生态系统的月水文过程进行全面、系统地研究。结果表明:(1)在降雨分配过程中,80.39%的雨量分配是在土壤层完成的;其次,林冠截留率较大,占降雨量的17.92%,并且随着林龄的增大,单位面积产生的截留越强;单位面积产生径流量最小,仅为降雨量的2.75%,其中,单位面积裸地的产流最大,分别为草地和林地的5.4,12.5倍。(2)蒸发散是流域森林生态系统的最大损耗方式 ...

The coordination of dehydration tolerance and avoidance in oaks is mediated by leaf habit across a precipitation gradient

open access: yesFunctional Ecology, Volume 40, Issue 3, Page 750-763, March 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Forests worldwide are increasingly impacted by drought due to climate change, prompting plants to adapt through dehydration tolerance (DT) and avoidance (DA), two distinct physiological strategies.

Mitigating light pollution impacts on arthropods based on light‐emitting diode properties

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Light pollution from artificial light at night (ALAN) is a significant environmental problem with far‐reaching consequences for ecological systems. Recent innovations in light‐emitting diode (LED) technology may offer sustainable outdoor lighting solutions, but scientific evidence is lacking. We investigated the effects of various LED lighting

Conservation grounded in traditional ecological knowledge, culture and hunting

open access: yesPeople and Nature, Volume 8, Issue 1, Page 256-266, January 2026.
Abstract For millennia, traditional hunting practices have provided a means of subsistence for numerous indigenous peoples worldwide. Not only do managed traditional hunting practices perpetuate Traditional Ecological Knowledge (TEK), but they also promote the sustainable utilization of natural resources.

森林生态系统生态资产核算的模式与方法

open access: yes, 2008
全球变化背景下,植被对CO2的减排作用得到了广泛关注。森林生态系统具有诸多功能,不同功能的货币化基准难以统一,是进行总体生态资产价值定量核算的制约要素。在资源、环境与生态经济原理指导下,分析相关方法评估生态系统生态资产的可行性,选择量化评估参数,并通过多种模式与方法进行估算乌鲁木齐城市2004年森林生态系统的生态资产。森林生态系统涵养水源类、生物多样性维持类、净化空气类、保护土壤类以及大气调节类生态资产分别为0.2248×108元、10.6088×108元、0.6308×108元、0.2592 ...
