麋鹿常见疾病及其防治

open access: yes野生动物学报, 2021
野生动物疾病与人类的健康息息相关。麋鹿(Elaphurus davidianus)是我国特有湿地物种,国家一级保护野生动物,世界自然保护联盟(IUCN)物种红色名录将其濒危等级定为野外灭绝(EW)。世界各地现存的麋鹿均为19世纪末保存在英国乌邦寺的18只麋鹿的后代,麋鹿经历了多次遗传瓶颈,遗传多样性较低,其疾病类型具有自身特性;虽然目前麋鹿种群逐渐扩大,但疾病仍是影响麋鹿种群健康和稳定扩大的重要因素。结合日常饲养管理,从细菌、病毒、寄生虫和普通疾病四大类型方面,综述了国内外麋鹿常见的疾病 ...

D-loop Sequence Variation of Mitochondrial DNA in Captive Chinese Alligator [PDF]

open access: yes, 2003
扬子鳄 (Alligatorsinensis)是中国特有的珍稀爬行动物 ,至 2 0 0 0年 ,野生扬子鳄的个体数已不足 15 0条 ,作为保护这一物种的措施之一 ,先后于 80年代初建起了 2个养殖场 ,现人工繁殖的扬子鳄总数已达 90 0 0余条。为揭示扬子鳄种群遗传多样性 ,从两个饲养种群中采集了 42个个体的样品 ,其中宣州样品 33个 (XZSP) ,长兴样品 9个(CXSP) ,用PCR方法扩增mtDNA控制区 ,扩增产物纯化后直接用ABI 310全自动遗传分析仪荧光标记测序 ,得到其中 ...

Perinatal outcomes of twin pregnancies complicated by early twin‐to‐twin transfusion syndrome treated with fetoscopic laser surgery

open access: yesUltrasound in Obstetrics &Gynecology, Volume 67, Issue 4, Page 461-469, April 2026.
ABSTRACT Objective The aim of this study was to evaluate the perinatal outcomes of monochorionic diamniotic (MCDA) twin pregnancies complicated by early twin‐to‐twin transfusion syndrome (TTTS) treated with fetoscopic laser surgery (FLS), and to compare rates of fetal survival across Quintero stages.

“Not a Single Leaf Is Meant to be Taken With You”: Conservation Motivations and Belief Systems in a Khasi Sacred Landscape of Meghalaya, India “一片叶子都不许带走”:印度梅加拉亚邦卡西族神圣景观中的保护动机与信仰体系

open access: yesIntegrative Conservation, Volume 5, Issue 1, Page 5-9, March 2026.
This study examines the Mawphlang Sacred Forest in Meghalaya as a culturally embedded model of community‐led conservation. Drawing on qualitative fieldwork, it highlights how spiritual reverence, sacred taboos, and ancestral authority shape ecological stewardship, complementing formal governance systems.

大兴安岭南麓东北马鹿种群遗传多样性分析

open access: yes野生动物学报, 2023
由于人类活动干扰及自然环境变化,东北马鹿(Cervus elaphus xanthopygus)的生存面临诸多问题。为掌握东北马鹿遗传多样性现状,进而为马鹿种群的健康状况提供评估依据,利用线粒体Cyt b基因和微卫星2种分子标记对内蒙古大兴安岭南麓高格斯台罕乌拉国家级自然保护区内的东北马鹿进行种群遗传多样性评估。结果表明:246份新鲜马鹿粪便隶属于182只个体;微卫星标记表明平均期望杂合度为(0.729±0.016),平均观测杂合度为(0.768±0.029),线粒体标记表明单倍型多样性为(0.347 ...

Genetic origins and climate‐induced erosion in economically important Asian walnuts

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract The global climate is undergoing unprecedented changes, posing significant threats to species persistence. However, the spatiotemporal impacts on genetic diversity remain poorly understood, hindering species conservation and management. Walnuts, generally referred to as Juglans regia and J. sigillata, are economically vital in Asia, but little

组蛋白化学修饰与12/15-脂氧化酶代谢途径在糖尿病肾病发展中的作用

open access: yesZhongshan Daxue xuebao. Yixue kexue ban, 2023
糖尿病肾病(DKD)是糖尿病患者最常见的微血管并发症之一,也是终末期肾衰竭的主要原因,其发病机制比较复杂。大量实验证实表观遗传学机制包括组蛋白化学修饰与脂质代谢产物12/15脂氧化酶(12/15-LO)参与调控DKD的特征性病理生理过程,本综述将从他们之间的相互作用关系出发,进一步探讨DKD发病机制,为DKD的治疗提供新的研究方向。
