Bright spots for advancing ecological understanding and conservation decision‐making
Conservation Biology, Volume 39, Issue 6, December 2025.Abstract A lot can be learned by studying bright spots—defined as unexpected positive outcomes. In fields like public health, education, and oncology, identifying factors behind bright spots reveals previously unknown drivers of success that can be replicated elsewhere.

Shuitu Baochi Xuebao, 2005 以黄土丘陵区安家沟小流域为例,计算了植被最小需水量,评价了不同植被类型的生态用水量。研究结果表明:(1)土壤含水量、蒸散量均与植被类型和降雨量密切相关。对于相同年份,乔灌林地的土壤含水量和蒸散量都显著地大于农地;对于相同的植被类型,干旱年份(2 0 0 2年)的土壤含水量和蒸散量都显著小于湿润年份(2 0 0 3年)。(2 )从月尺度来说,不论是干旱年还是湿润年,植被生态用水在生长季节旺季均低于其最小生态需水量;从年尺度来说,干旱年份所有植被生态用水均低于其最小生态需水量,但湿润年份所有植被(除小麦外 ...

Endemic plants in coastal zone and islands in South China and construction of vegetation landscape on islands [PDF]
, 2015 我国南方海岸带及海岛有丰富的植物资源。在海岸带及海岛大开发的背景下，植物资源的保护和合理利用在构建生态安全屏障、绿化和美化方面具有举足轻重的地位。由于生境特殊，海岸带及海岛植物具有特有种比例高和分布区狭窄的特点。在自然因素和人为因素的双重作用下，我国南方海岸带及海岛植物资源正在经历大规模的衰退。此外，土壤盐渍化、盐雾、干旱及大风等不利环境条件给沿海防护林建设、城镇和道路绿化、海岛植被修复等带来了诸多困难，盐害问题日益突出。抗风、耐土壤盐、耐盐雾植物资源的筛选和利用，以提高存活率 ...

Mining-affected water resources and ecological effects in ecologically fragile mining areas of western China [PDF]
The ecologically fragile mining area in the west is an important coal production base in China, and the current scale and intensity of coal mining has far exceeded its environmental carrying capacity, which is very likely to cause irreversible damage to ...

Conservation Biology, Volume 39, Issue 6, December 2025.Abstract Forest cover is positively associated with fish biomass and fisheries yield in the Amazon River floodplain, and many species enter flooded forests to feed, spawn, or seek refuge from predation. Floating macrophyte beds, known as floating meadows, in Amazon floodplains support high fish diversity and serve as nursery habitat for many fishes of ...

Structure Genetic Mechanism and Provenance Analysis of Badain Jaran Desert, Northwest China [PDF]
, 2015 由于长期构造地质作用，我国西北部地区变得气候持续干旱，生态极为脆弱。生态系统的不断恶化，加上人为因素的影响，塔克拉玛干、腾格里、毛乌素、巴丹吉林沙漠等沙漠化形势越来越严峻，尤其每年冬春季节将频发沙尘暴活动，严重影响了人民群众的正常生活。而巴丹吉林沙漠正好地处我国东、西部沙区之间的过渡敏感地带，以发育有复杂高大沙山，分布着星罗棋布的湖泊而闻名于世，具有较高的学术研究价值，一直以来倍受中外学者的高度重视和关注。 迄今为止，学术研究主要关注点在沙漠物源、成因机理、侵蚀过程和治理方法等方面 ...

Global Change Biology, Volume 31, Issue 11, November 2025.This study assessed the potential impacts of climate and land‐use change on soil fungal diversity across four North American biomes. We found that climate change typically caused both diversity losses and gains, particularly in coniferous forests and among arbuscular mycorrhizal fungi, whereas land‐use change mainly reduced diversity, especially in ...

, 2009 通过2004年2～12月对古尔班通古特沙漠南缘2年生人工梭梭和沙拐枣混交林内3条典型坡面土壤水分进行了系统监测与研究。结果表明:人工林土壤水分状况受季节性降水、人工林种植密度、地形因子的影响而出现明显的时空分异。在空间上将土壤水分变化划分为三层,0～30cm为活跃层,30～60 cm为次活跃层,60～120 cm为相对稳定层。通过主成分分析,得出地形因子、种植密度对0～30 cm土层土壤水分的影响次序为坡度>坡向>种植密度>高程,30～60 cm土层为坡向>种植密度>坡度>高程,60～120 ...

Integrative Conservation, Volume 4, Issue 3, Page 476-490, September 2025.The leaf functional traits of angiosperms and gymnosperms in mountain ecosystems significantly influence phyllosphere fungal diversity. These traits are critical for understanding fungal stress resistance and elevational adaptation, which aids in predicting plant responses to climate change.
