Integrative Conservation, Volume 4, Issue 3, Page 430-441, September 2025.Our study identifies southern China, including mountainous regions and islands, as key areas rich in phylogenetic diversity, and phylogenetic endemism of lizards that are currently under‐protected. Current protected areas however do not adequately cover regions that are critical for preserving the evolutionary history of lizards.

Wildlife Letters, Volume 3, Issue 3, Page 109-117, September 2025.We found that the Asian Openbill primarily roosted near waterbodies and frequently used farmland habitats, with significantly higher populations observed during the breeding season. Farmland and wetland areas exhibited a positive effect on the species' habitat use.

Seasonality of temperature dependence of methane fluxes from natural wetlands
Functional Ecology, Volume 39, Issue 9, Page 2383-2397, September 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Temperature dependence is a crucial parameter in estimating methane (CH4) fluxes from natural wetlands, yet our understanding of this parameter remains inadequate. Seasonal fluctuations in water levels and ecosystem productivity lead to seasonal differences in CH4 ...

Zhongguo shiyan zhenduanxue, 2019 目的观察长春市2型糖尿病(T2DM)患者糖化血红蛋白(HbA1c)的冬夏季变化。方法选取2015年12月至2018年9月于吉林大学第二医院就诊的长春市2型糖尿病患者,且病程5年以内、病情稳定者共650人为研究对象,观察其冬季(12月至次年2月)及夏季(7月至9月)的HbA1c值。所有观察对象按冬、夏季分为两组,探究糖化血红蛋白与季节是否具有相关性,同时探究所有观察对象的一般情况及相关代谢指标是否也受季节变化的影响。结果糖化血红蛋白(HbA1c)存在冬季高、夏季低的统计学差别[(9.71±1.84)%比 ...

Integrative Conservation, Volume 3, Issue 3, Page 230-243, September 2024.Tropical secondary forest at early sucessional stage had higher diamter growth rate and mortality rate, however, these forests also are more risked to droughts and high temperatures. Rising temperatures and more frequent droughts may decrease the carbon sink capacity of tropical forest ecosystems. Abstract Tropical forests are major carbon sinks on the

Integrative Conservation, Volume 3, Issue 3, Page 168-182, September 2024.Using long‐term field data, we examined the impact of severe droughts on the health, reproductive success, and behavior of the critically endangered Verreaux's sifaka (Propithecus verreauxi) in Madagascar's seasonally dry tropical forest. Despite reduced availability of high‐quality foods, sifaka exhibited stable body condition and reproductive success,

Shuitu Baochi Xuebao, 2002 对经过 10年半旱式免耕定位试验的水稻土主要微生物类群数量和微生物生物量的变化进行对比研究 ,结果表明 :实行半旱式厢作及垄作免耕法能够迅速地提高土壤有机质、全氮、全磷和速效氮、磷的水平 ;微生物数量和微生物生物量变化一般存在季节性规律 :春季高 ,夏季至夏末降低 ;各处理土体上层和下层 (0～ 7.5 cm,7.5～15 cm)的基本肥力特征及微生物特征无明显区别 ;免耕处理土壤 ,其微生物的季节性变幅较小 ,垄上或厢上土壤微生物生物量甚至表现反季节性 ,整个生长季节内稳中有升 ...

野生动物学报, 2006 本文通过潘文石对22只秦岭大熊猫的家域观察资料为基础,获得生态年龄段和家域对数转换值等次生数据, 并以次生数据为基础,对不同生态年龄段和不同季节大熊猫的家域和个体季节性迁移面积的动态特征进行定性比较分析,通过季节、性别和年龄对秦岭大熊猫种群家域动态的影响机制进行了探讨,结果发现以下新细节: （1）虽然在同一季节,大熊猫家域面积随着年龄的增长逐渐增加,但雌性个体家域面积增加不大,雄性个体也仅在夏季家域面积增加极大,秋冬季增加也不大; （2）同一生态年龄段,秦岭大熊猫家域面积:全年>秋冬季>夏季; （3 ...
