Integrative Conservation, Volume 4, Issue 1, Page 10-19, March 2025.Brief summary: Urbanization is leading to “Nature‐deficit Disorder” that threatens children's health and the sustainable development of humanity. This study implements a new solution—the Mini Botanical Garden, which integrates some of the functions of botanical gardens into community green spaces to popularize nature education in the city.

Shuitu Baochi Xuebao, 2019 探讨水地条件下种植模式对夏玉米产量及水分利用的影响，为夏玉米节水种植高产稳产栽培提供依据。以玉米品种"登海685"为试验材料，研究宽垄沟播和等行距平播模式下不同种植密度（6.00，6.75，7.50万株/hm2）对夏玉米生长发育、产量、养分吸收及水分利用率的影响。结果表明：沟播种植模式较平播增加玉米植株株高，使茎粗和单株干物质重降低。沟播模式的穗性状比平播处理较优，单穗重增加，且受种植密度影响较小，表现出明显的边行优势。沟播模式的玉米叶片叶绿素相对含量始终高于平播处理，生育期延长 ...

Integrative Conservation, Volume 3, Issue 4, Page 426-437, December 2024.Globally, human‐use landscapes are being reported to be large carnivore habitats. The study examines the spatial variation of leopard density in the forest‐human use landscape mosaic of the Duars region of West Bengal. Tea estates overshadow forested areas in terms of the absolute density of leopards, reiterating the potential of human‐use areas to be ...

Shuitu Baochi Xuebao, 2021 土壤可溶性氮组分是氮循环中最活跃的一环，是联系"植物—土壤氮组分—土壤养分"的关键纽带。为探讨植被类型对黄土丘陵区土壤氮素累计及其有效性的影响，以黄土丘陵区4种典型植被（荒草地、沙棘林地、文冠果林地、云杉林地）为研究对象，分析0—10，10—20，20—40 cm土层可溶性有机氮（SON）、铵态氮（NH4+—N）、硝态氮（NO3-—N）含量，密度及其所占TN比例在不同植被间的差异。结果表明：与荒草地相比，0—40 cm土层中SON含量整体表现为云杉林地最高（19.0%），文冠果林地和沙棘林地分别减少7 ...

, 2012 利用盐生植物抑制藻类生长是防治海洋赤潮发生的一种新兴技术.本文以中国近海典型赤潮原因种中肋骨条藻为对象,研究了滩涂盐生植物盐角草对藻生长的影响及其机制,并利用高效液相色谱技术分析潜在的抑藻物质.共培养实验结果显示,在营养盐充足的条件下,盐角草能够显著抑制中肋骨条藻的生长,降低藻生长水体叶绿素A(CHlA)浓度.除盐角草根系水提物之外,其余3种有机相提取物均能抑制藻的生长,改变藻细胞大小,并且影响单个细胞的CHlA含量.各种有机相提取物的抑制作用具有浓度效应,随浓度升高抑制作用增强 ...

Integrative Conservation, Volume 3, Issue 4, Page 330-341, December 2024.Despite the availability of data on plants and their pollinators from the Indian sub‐continent, detailed investigations that explain the intricacy of the mutualistic interaction at both population and community levels have largely been limited. This review explores the current status of pollination ecology research in India and suggests future ...

Inhibitory Effect of Salt Marsh Halophyte Salicornia Europaea on Prorocentrum Donghaiense [PDF]
, 2014 利用植物抑制藻类生长是目前海洋赤潮治理的有效生态手段之一。以东海原甲藻为材料,研究了滩涂盐生植物盐角草对东海原甲藻生长的抑制效应。结果显示:盐角草过滤培养液和4种根的有机相提取物(甲醇相、正丁醇相、氯仿相和石油醚相)能显著抑制东海原甲藻的生长,改变细胞大小。其中,石油醚相和正丁醇相提取物还能影响藻细胞CHl A含量。有机相提取物中以甲醇相提取物的抑制效果最强,对盐角草甲醇相提取物进行gC-MS分析,得到27种化合物,含量最高的3个组分为5-羟甲基-2-呋喃甲醛、棕榈酸和4-乙烯基-2-甲氧基-苯酚 ...

Integrative Conservation, Volume 3, Issue 4, Page 342-352, December 2024.Human activity, particularly the increase in forested areas across the western Mediterranean, has impacted squamate diversity. This study investigated the impact of canopy cover on squamate assemblages, finding the highest diversity in areas with moderate tree cover.
