High nitrogen enrichment buffers plant photosynthesis against herbivory damage
Functional Ecology, Volume 40, Issue 1, Page 229-238, January 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Herbivorous insects and nitrogen deposition are key drivers of ecosystem productivity under global change. However, their combined effects on plant photosynthesis, particularly during insect outbreaks, remain poorly understood in natural ecosystems.

野生动物学报, 1984 啮齿动物对人类是有害的。它盗吃粮食、咬坏家俱,破坏草原,危害森林更新,传染疾病。由于它们适应性强,分布广,繁殖力高,数量增殖快,所以对人类的危害程度日趋严重。已引起人们的关注。

Integrative Conservation, Volume 4, Issue 4, Page 652-664, December 2025.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.

Dianci bileiqi, 2016 为合理地防护雷电对人体带来的伤害,需要研究雷电对人体的伤害机理。介绍了雷电对人体的危害方式和雷电危害能量阈值。通过建立人体电路模型,利用ATP软件模拟雷电和与人体模型间相互作用,具体分析不同土壤电阻率情况下,跨步电压、接触电压和转移电位作用下流经心脏的电流,计算导致心室纤维性颤动的比能量。仿真结果表明:土壤电阻率的增大有助于降低跨步电压和转移电位对人体的伤害;接触电压更容易给人体带来致命性危害。雷电作用下人体伤害机理需要作进一步研究。

草原毛虫(Gynaephora ruoergensis Chou et yin)病毒的发现和鉴定
四川大学学报. 自然科学版, 1984 草原毛虫属鳞翅目（Lepidoptera）毒蛾科（Lymantriidae）的一种主要牧草害虫;该虫与草原鼠害并称为我国草原的两大灾害。草原毛虫分布广,仅川西北草原受害的草场面积已达1600万亩以上;为害时间长,通常每年四月越冬幼虫开始出现活动为害,至九月化蛹,为害期长达半年之久,整个放牧期间持续为害。草原毛虫危害的草类,正是牲畜的主要牧草。该虫多集中于草料丰茂地带,虫口密度多达170——530头/米2。川西北草原每年因该虫的危害损失天然牧草,相当于100万只羊单位的全年饲料,价值数千万元。

Downlisting and recovery of species assessed by the IUCN
Conservation Biology, Volume 39, Issue 6, December 2025.Abstract Despite the increasing number of species assessed for extinction risk by the International Union for Conservation of Nature (IUCN) (163,040 species as of 2024), only about 1 in 1,000 have been downlisted due to genuine population improvement. Although this rare conservation achievement has been widely celebrated in several recent cases, some ...

Zhejiang Daxue xuebao. Lixue ban, 2015 利用1971~2013年永嘉县夏季高温资料，建立高温过程的时间序列，分析了夏季高温天气的气候特征，并对出现危害性高温时的预警指标作了进一步探讨.研究表明：永嘉县夏季高温天气具有显著的局地性特征，且高温多集中在7月中下旬和8月上旬；副热带高压是影响本地夏季高温的主要天气系统，当本站处在副高脊线附近，高空下沉气流明显，低层在暖脊或暖中心附近，中高层为西南（或偏西）气流时，容易出现危害性高温；危害性高温出现时，天况稳定、云量偏少、日照时数较长、能见度较好、风速较小，且以西南风居多.
