We developed an effective ex‐situ conservation approach for an endangered orchid species, Dendrobium sinominutiflorum. A compatible fungal strain Tulasnella sp. was obtained by using in‐situ seed baiting technique. The Symbiotic germination with Tulasnella sp. significantly promotes seed germination and seedling growth.

ABSTRACT The urgent environmental crisis caused by polyethylene terephthalate (PET) waste necessitates efficient upcycling strategies. Herein, we establish a novel pathway to transform waste PET plastic into a high‐performance catalytic material for mediating the oxygen evolution reaction (OER). Through a one‐step hydrothermal process, waste PET serves

通过对重庆市36座水库的监测,各水库chla值范围为1.59~52.3mg/m3;TP范围为0.002~0.598mg/L;TN范围为0.52~5.94mg/L;SD范围为0.48~3.2m;CODMn范围为0.75~9.3mg/L。CODMn、TN与chla之间呈极显著的正相关关系,SD与chla呈极显著的负相关关系,TP与chla的相关性较差,利用回归分析得出TN、SD、CODMn与chla的线性关系。利用修正的卡尔森指数对水库进行富营养化评价,结果表明:35座大中型水库达到富营养化的水库为27座 ...

Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecological communities are stressed by rapid and complex anthropogenic changes, threatening the persistence of biotic interactions and ecosystem functioning. Plant–pollinator communities, for instance, undergo structural transformations as a result of land‐use change ...

基于2010年春季(5月)、夏季(8月)、秋季(11月)和2011年冬季(2月)对岱衢洋海域进行的4个航次网采浮游植物的调查资料,对该海域浮游植物的种类组成、优势种、细胞丰度分布以及生物指数与环境因子的相关性进行调查研究,并用富营养化指数、水质综合指数、浮游植物多样性指数进行水质状况评价.经初步分析,共鉴定出浮游植物50属116种,其中硅藻门37属92种,甲藻门10属20种,绿藻门和蓝藻门各2种.全年浮游植物优势种主要为硅藻门的琼氏圆筛藻(Coscinodiscus jonesianus)、星脐圆筛藻 ...

Abstract Measuring area‐based conservation outcomes in tropical forests is challenging due to cryptic human disturbances (e.g., hunting). As a result, comparative studies of management strategies providing quantitative outcomes remain scarce, especially in the Neotropics.

富营养化水体流经北运河下游天然湿地后,水质由重度富营养向中度富营养状态转变。水质检测结合荧光原位杂交(FISH)菌种识别技术结果表明,天然湿地对氮的去除除了生物吸收外,硝化-反硝化也是重要途径。对磷主要由生物吸收及底泥吸附截留去除。对叶绿素a的去除归因于挺水植物遮蔽阳光,并与藻类竞争营养物质而限制了藻类生长。最后建议夏、秋季采取曝气等人工强化措施,以提高天然湿地的水质稳定效果。

We profiled nutritional and physiological markers in captive sifakas, endangered primates from Madagascar, managed in expansive, non‐native forest enclosures. Variation in many markers reflects freely foraged diets and the energy required to maintain homeostasis under more naturalistic conditions.

Read the free Plain Language Summary for this article on the Journal blog. Abstract In the Southwest Australian Biodiversity Hotspot, the greatest plant species diversity tends to occur on the most phosphorus (P)‐impoverished soils. Many plant species in this P‐impoverished environment release root carboxylates that mobilise soil P which is a more ...

Trait‐Mediated Competition for Light Underpins Plant Diversity Loss Under Eutrophication
Eutrophication often reduces plant diversity by making the ground layer darker, which reduces understory plants. In a natural alpine grassland, we added LED light beneath the canopy and saw diversity return across different nutrient treatments: with added nitrogen fertilizer, light mainly increased new species; with added phosphorus fertilizer, it ...
