Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant phenology is crucial for understanding plant growth and climate feedback. It affects canopy structure, surface albedo, and carbon and water fluxes. While the influence of environmental factors on phenology is well‐documented, the role of plant intrinsic factors ...

主要研究了石菖蒲、泽泻、菖蒲、黄花鸢尾、千屈菜这5种常见水生观赏植物对城市污水的生理生化变化,分别在第5 d,10 d和15 d对植物叶片膜脂过氧化(MDA、电导率)、体内保护系统酶(CAT、POD)、非酶类(游离Pro)及根系活力等抗性生理指标进行测定,探讨植物抗污水逆境的能力。研究结果表明,不同植物适应污水环境能力不同。其中,黄花鸢尾在污水处理下的抗逆性最强,与对照相比其电导率和丙二醛含量变化不大,而一些植物在实验初期受到污水胁迫,电导率和丙二醛含量较对照有上升的现象;同时 ...

The Hour that Never Comes and the Time that Remains
Abstract This essay proposes a symbolic and clinical investigation of psychic temporality through two archetypal experiences of time: the hour that never comes and the time that remains. Drawing on analytical psychology, trauma theory and aesthetic philosophy, text explores how certain forms of suffering resist chronological resolution and persist as ...

在大田高产栽培条件下.研究了不同施氮水平对豫麦49-198根际微生物和土壤酶活性的影响。结果表明:豫麦49-198根系土壤蛋白酶活性和脲酶活性随生育时期推进均呈先上升后下降的变化趋势.蛋白酶活性、脲酶活性分别在拔节期和返青期达到最大值。在同一生育时期内,随着施氮水平的提高,蛋白酶活性呈先增加后降低的变化趋势.其中以N2(180kg/hm^2)处理的蛋白酶活性最高,但N4(360kg/hm^2)处理的蛋白酶活性仍大于对照N1(0kg/hm^2);脲酶活性随施氮水平的提高呈上升趋势.以N4(360kg/hm^

Scaling area‐based conservation, including initiatives led or comanaged by Indigenous Peoples and local communities, is a flagship goal of the Kunming‐Montreal Global Biodiversity Framework. Conservationists often aspire to scale initiatives, but this is rarely achieved in practice. Identifying and addressing factors that limit initiative adoption (i.e.

在连续6年稻麦轮作系统中,研究不同秸秆施用方式下接种蚯蚓对土壤微生物生物量、活性(基础呼吸)及群落功能多样性(BIOLOG单一碳源利用指纹方法)的影响,试验设5个处理:对照(CK)、秸秆表施(M)、秸秆混施(I)、秸秆表施且接种蚯蚓(ME)、秸秆混施且接种蚯蚓(IE)。不同秸秆施用下接种蚯蚓均对土壤微生物生物量、微生物生物活性和群落碳源利用能力产生显著影响:两种秸秆施用方式下接种蚯蚓均增加微生物生物量;秸秆表施并接种蚯蚓导致微生物活性、碳源利用丰富度和多样性指数均降低,而在秸秆混施下则均升高 ...

西南岩溶区土壤微生物生态作用的初步研究--以桂林丫吉村岩溶试验场为例
对桂林丫吉村岩溶试验场不同岩溶地貌的土壤微生物生理群的分布特征及土壤生物活性强度进行了研究,结果表明土壤生物活性强度的变化与土壤微生物数量的变化趋势基本一致。同时讨论了土壤微生物数量与土壤有机质、全N、有效N和速效P的相关性及微生物生理群在该场区氮循环中的生态作用。

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.

Abstract Illegal wildlife trade (IWT) is one of the largest global illegal activities, and it negatively affects biodiversity and sustainable development worldwide. DNA barcoding coupled with high‐throughput sequencing (i.e., metabarcoding) is useful in identifying taxa affected by IWT and has been used routinely for decades.
