Exposure of wetlands important for nonbreeding waterbirds to sea‐level rise in the Mediterranean
Conservation Biology, Volume 38, Issue 6, December 2024.Abstract Sea‐level rise (SLR) is expected to cause major changes to coastal wetlands, which are among the world's most vulnerable ecosystems and are critical for nonbreeding waterbirds. Because strategies for adaptation to SLR, such as nature‐based solutions and designation of protected areas, can locally reduce the negative effects of coastal flooding

Linking extinction risk to the economic and nutritional value of sharks in small‐scale fisheries
Conservation Biology, Volume 38, Issue 6, December 2024.Abstract To achieve sustainable shark fisheries, it is key to understand not only the biological drivers and environmental consequences of overfishing, but also the social and economic drivers of fisher behavior. The extinction risk of sharks is highest in coastal tropical waters, where small‐scale fisheries are most prevalent.

Preliminary study on population genetic diversity of the little egret (Egretta garzetta) with microsatellite loci [PDF]
, 2012 白鹭（Egrettagarzetta）是在全球分布广泛的湿地鸟类，曾被列入《濒危野生动植物种国际贸易公约》名单附录III（2003）。为对其遗传多样性等种群遗传学特征进行研究，本研究筛选获得用于白鹭种群遗传学研究的12个多态性微卫星位点，建立了白鹭羽毛的微卫星分型技术体系。在此基础之上，本文初步研究了中国沿海三个白鹭繁殖种群（广西防城港的巫头村、福建厦门猫屿、浙江舟山馒头山）2010年的种群遗传多样性和遗传结构。 微卫星筛选主要利用跨种扩增的方法，从黄嘴白鹭和棕颈鹭的已知位点中选择高多态性的位点进行扩增，

Adivasi (Tea Tribe) worldviews of living close to wild Asian elephants in Assam, India
Conservation Biology, Volume 38, Issue 6, December 2024.Abstract In Assam state, northeastern India, human–elephant conflict mitigation has included technocentric measures, such as installation of barriers, alternative livelihoods, and afforestation. Such measures treat conflict as a technical problem with linear cause–effect relations and are usually ineffective over the long term because they do not ...

, 2006 对青海湖裸鲤55个个体Cytb基因全序列进行了测定和分析,探讨了种群结构和群体遗传多样性。用MEGA2.1软件分析了碱基组成和序列变异;以黄河花斑裸鲤为外群,构建了单倍型的NJ树;用Arlequin Ver.2 000程序计算了群体内遗传变异值(Fst)。结果显示,青海湖裸鲤群体没有显著的种群结构,提示青海湖裸鲤群体内存在广泛的基因交流;种群的遗传多样性较低(π=0.7828±0.0532),青海湖裸鲤种群很可能在历史上遭受过严重的“瓶颈效应”

The enigmatic life history of the bamboo explained as a strategy to arrest succession
Ecological Monographs, Volume 94, Issue 4, November 2024.Abstract Bamboos are perennial woody grasses that display an enigmatic mix of traits. Bamboo is highly shade intolerant like early‐successional trees. Without secondary xylem, bamboos cannot continue to grow once they reach a maximum height or replace xylem damaged by hydraulic stress and must instead replace each stem after a few years using ...

Assessing the risk of overexploitation to a tarantula species in the pet trade
Conservation Biology, Volume 38, Issue 5, October 2024.Abstract The global pet trade in invertebrates remains poorly understood and underrepresented in policy and research. Tarantulas are a highly traded invertebrate group. Many individuals in trade are wild caught, and trade regulation is often lacking, raising concerns about the effect of trade on local ecosystems and populations.

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,

Effect Structure of Iron Core on Kinetics of Iron Release from Horse Spleen Ferritin [PDF]
, 2001 建立H+参与马脾铁蛋白释放铁的动力学方程。H+以 1 / 2级反应方式参与铁蛋白释放铁核表层的铁。在酸性介质 ( pH 6 5)中 ,铁蛋白释放铁的总平均速率 ( 332Fe3+/HSF·min)比在碱性介质 ( pH8 0 )中释放铁的总平均速率 ( 73Fe3+/HSF·min)高 4 6倍。铁蛋白的铁核结构和外加的磷酸盐均能影响该蛋白释放铁的速率 ,但并不改变其反应级数。A Kinetic equation of iron release with H + existing was ...
