Conservation Biology, EarlyView.Abstract Achieving global conservation policy goals requires the ability to set and measure progress toward science‐based targets for biodiversity. The species threat abatement and restoration (STAR) metric was developed to enable actors to set science‐based targets for species.

Shuitu Baochi Xuebao, 2005 试验筛选几种药剂对毛豆进行喷施处理,测定其在水分胁迫下对毛豆幼苗有关营养生长指标和生理指标影响,结果表明:几种药剂处理后均可比对照促进苗增高、增加叶面积、促进根系的生长、增加根系活力、抑制丙二醛增生、降低细胞膜透性和提高叶绿素含量、相对含水量、脯氨酸含量、细胞保护酶的活性等,有力地增强了毛豆幼苗对水分胁迫的抵抗能力,从叶面喷施几种药剂对毛豆的生长及生理指标的影响进行综合分析可知,几种药剂以油菜素内酯为最优、其它依次为三十烷醇、黄腐酸盐、爱多收 ...

野生动物学报, 2017 2006～2015年间,通过驯化,在非麻醉状况下成功采集了114只大熊猫(♀58只,♂56只)2 399份血样进行了50项生理生化指标检测,建立非干扰条件下大熊猫正常生理生化指标参考范围。统计分析发现某些生理生化指标随着年龄的增长表现出显著性差异; 酶类指标波动范围较大,个别指标表现出与年龄相关的变化趋势; 成年组雌性和雄性大熊猫生理生化指标较幼年组、亚成年组和老年组表现出更多性别相关的差异,临床上需按性别区别对待。受种群健康状况改善、样本数量和采样方式改变的影响 ...

Drivers of bat researchers’ intent to adopt field hygiene practices
Conservation Biology, EarlyView.Abstract Infectious disease is a growing threat to wildlife, with zoonotic transmission most likely at the human–wildlife interface. One underappreciated activity at this interface is fieldwork with wild animals, but associated risks can be mitigated through field hygiene (FH) practices, such as using personal protective equipment and other appropriate

Shuitu Baochi Xuebao, 2017 旨在通过改变生物质炭在植烟土壤中的施入量，明确优质烤烟在生产环节的根系发育、叶片光合特性及地上和地下部分协调生长的生理指标，以改善东北植烟区烤烟品质较差的现状，于2015—2016年采用大田试验方式，设置6个处理（CK、T1、T2、T3、T4、T5），与当地常规施肥相比，各处理氮肥施入量均减少40%，分析不同生物质炭用量对烤烟旺长期根系生理指标与叶片光合生理指标的影响。结果表明，烤烟烟株在旺长期根系发育状况与光合生理指标、叶绿素含量、叶面积系数的状况是协调一致的；施用生物质炭2 400 kg ...

Mechanistic Study on Selenite Absorption and Metabolism Promoted by Exogenous Nitric Oxide in Rice Seedling Roots [PDF]
, 2015 硒(selenium，Se)作为人和动物的必需元素之一，有非常重要的生理功能。可食性植物是人和动物的主要硒源，探索植物硒累积分子机制以及寻找提高植物硒含量的策略具有重要现实意义。 一氧化氮(nitricoxide，NO)作为一种重要的生物信号分子，在动植物体内起着重要的作用。低浓度NO对植物的生长发育以及多种逆境胁迫抗性具有重要影响。已有部分研究表明硒能引起植物体内NO的变化，且NO能缓解硒诱导的水稻脂质过氧化，但目前关于NO对硒吸收代谢调控的分子机制研究尚未报道。本文以重要的粮食作物水稻 ...

Advancing conservation breeding programs for marine invertebrates
Conservation Biology, EarlyView.Abstract In the face of ecosystem change and biodiversity loss caused by climate change and other stressors, conservation breeding, or captive breeding, with the aim of reintroduction for wild population recovery, is an emerging tool for preventing species’ extinction and rehabilitating ecosystems.

Conservation Biology, EarlyView.Abstract Although significant biodiversity has been safeguarded by protected areas (PAs), biodiversity trends continue downward. Within the frameworks of the EU Biodiversity Strategy for 2030 and the new EU Restoration Regulation (2024), conserving critical biodiversity areas is essential.
