Internal physiological drivers of leaf development in trees: Understanding the relationship between non‐structural carbohydrates and leaf phenology

open access: yesFunctional Ecology, EarlyView.
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 ...

Analysis and Research on Moisture Detection System in Cigarette Processing Process [PDF]

open access: yes, 2015
在卷烟制造过程中,制丝线在线水分仪是控制制丝加工过程质量稳定、提高加工过程精度的关键检测控制仪器。制丝加工过程质量的判定离不开水分检测系统的完善,可以说,水分检测系统的好坏直接决定了制丝加工质量的优劣。然而,现阶段烟草行业在工艺质量水分检测系统的构建上却仍存在许多不足之处: 各卷烟生产企业对水分工艺指标没有统一的数据采集处理规则,企业内部不同生产点之间存在差异,同一生产点不同生产线存在差异,同一生产线不同水分检测点也存在差异,不同生产线同一水分检测位点也存在差异 ...

Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

Elevation, soil pH and calcium availability shape regional and local scale spatial patterns of PhoD gene abundance in tropical and subtropical forests

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Organic phosphorus mineralization is a critical process in the phosphorus cycle, governing phosphorus bioavailability for plants. The PhoD gene, which encodes the key enzyme alkaline phosphatase, serves as a valuable biomarker for this process.

Changes in the Infrared Spectra of Wood Produced by Desorption of Water [PDF]

open access: yes, 1968
水分の脱着によって起る木材の微細構造的な変化を明らかにするため赤外分光法の適用を試みた。木材中の水分の脱着により, その赤外線吸収スペクトルの吸収帯に変化が認められたのは3350, 1635, 1450, 1340, 1110, 1060および1040cm_-1である。これら吸収帯のうち3350と1635cm_‐1は吸着した水分子自体の脱着にもとずくものであり, 他の吸収帯は脱着による木材の微細構造の変化に対応するものと推定される。比較的変化量の大きい吸収帯1110, 1060および1040cm_ ...

Jellyfish blooms restructure plankton dynamics and trophic linkages in coastal waters

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Jellyfish blooms are increasing globally in frequency and intensity, introducing complex ecological interactions, yet the mechanisms by which they alter ecosystem structure remain poorly characterized due to a lack of sustained field observations.

古尔班通古特沙漠腹地土壤水分时空分异研究

open access: yesShuitu Baochi Xuebao, 2004
古尔班通古特沙漠土壤水分补给以积雪融水和雨水为主,土壤水分是维系古尔班通古特沙漠荒漠植被发育最主要的制约因子。选取沙漠腹地典型沙垄为研究区,并分地貌部位布设了土壤水分监测点、植物监测样方以及沙面蚀积监测铁钎和气象观测站,从而形成以土壤水分监测为主的综合监测场。通过野外标定,利用中子水分仪对典型沙垄的不同地貌部位土壤水分动态进行系统监测,结果表明:土壤水分受季节性积雪、降雨、地貌部位、地形起伏、植被盖度等因素的影响而出现明显的空间分异与时间变化。土壤水分的空间差异整体表现为垄问土壤水分高于垄顶 ...

open access: yes, 1956
【緒言】 砂丘地土壌の理化学的性質の改善保持に有機物質の施与と適当な水分補給とは,最も重要な事項である.著者らはこの有機物質の施与に関する試験を,第1ないし第2報において述べたが,土壌水分の補給については,現在において何等基礎的な試験は実施されていないのである.よってこのたびは第2報同様松葉の施与ならびに施肥を行い,さらに水分を補給して大豆のポット栽植試験を行った.しかしてこの水分補給による大豆の生育,収量等に,相当の好結果をもたらすに要する土壌水分量を調査し,さらに従来通常の土壌において ...

Strangers on the ladder of the party‐state: Women in teaching in Nationalist Taiwan, 1940s–1980s

open access: yesGender &History, EarlyView.
Abstract As the ruling party of a party‐state in China and Taiwan, the Nationalist Party (Kuomintang/Guomindang) built a close relationship with the teaching profession. Many teachers joined the party and there was a well‐trodden pathway from teaching into local representative politics and civil service.
