Integrative Conservation, EarlyView.This research reveals the functional stability of mixed species foraging flocks (MSF) and their foraging height change with different taxonomic differences along the elevational gradient at Knuckles Montane Reserve, Sri Lanka. This offers new insights into how MSFs sustain with the elevational gradients supporting the altitudinal shifting species ...

Zhejiang Daxue xuebao. Lixue ban, 2011 奥陶系碳酸盐岩储层是塔中地区重要的油气产层.测定塔里木盆地奥陶系热液矿物（方解石、石膏、重晶石等）及围岩的碳氧同位素以及锶同位素，分析结果显示，热液溶蚀围岩后释放的CO2可能是形成方解石中特征氧同位素组成的主控因素；自生碳酸岩矿物的碳同位素组成反映其在成岩期至少有2种碳源，早期形成的碳酸盐岩与二叠纪富13C的碳源相关，成岩早期至晚期的碳酸盐岩的沉淀或重结晶可能与由局部地质事件导致流体在沿裂缝系统运移时混合了有机质降解过程中产生的富12C的CO2有关；87Sr/86Sr值(0.708~0.718 ...

Community and population research of Tsuga longibracteata [PDF]
, 2016 长苞铁杉（TsugalongibracteataCheng），是属于松科（Pinaceae），铁杉属（Tsuga）的第四冰期孑遗植物；主要分布在我国22°49'-28°33'N，107°12'-118°14'E之间；由于自身更新速度缓慢以及长期的砍伐利用，其地理分布相对狭小且呈零星分布，分布区和居群规模在逐渐缩小和下降，面临着灭绝的危险；本文针对分布在福建省内各县市的长苞铁杉群落进行了基本区系特征、物种多样性、种群生命过程、分布格局和生态位等方面的生态学研究，结论主要如下： 1、各样地长苞铁杉群落在科 ...

Rare Metals, EarlyView.ABSTRACT Internal oxidation has been identified as an effective method for enhancing the strength of AgMg alloys. However, the concurrent occurrence of embrittlement remains inadequately understood, thus limiting their broader application. This study investigates the oxidation behavior of AgMg alloys with Mg concentrations ranging from 1 at% to 7 at ...

牛山湖两种不同生境小型鱼类的种类组成、多样性和密度 [PDF]
, 2007 研究了2003年春季浅水草型湖泊牛山湖小型鱼类空间分布(种类组成、多样性和密度等)与生境异质性之间的关系.根据水生植被状况、离岸距离和水深,选择了两种差异较大且有代表性的生境类型,即近岸沉水植物茂密的生境A和远岸沉水植物稀疏的生境B.使用围网(180m2)在这两种生境中进行小型鱼类的采样,采用多次标志回捕法和Zippin去除法估算了围网内小型鱼类的密度.结果表明,两种不同生境中小型鱼类的种类组成、多样性度量值和密度估算值均存在一定程度的差异:1)生境A中的渔获物由5科14种小型鱼类组成 ...

野生动物学报, 2010 1998、1999年福建省安溪县林业局开展了鸟类、兽类、两栖爬行类资源调查,基本摸清了安溪县范围内陆生野生动物资源状况。通过区系研究,表明安溪县的鸟类、兽类、两栖爬行动物在动物地理分布上的特征以东洋界的组成成分为主,在动物的二级区系组成上鸟兽类以华南区成分为主,两栖爬行类以华中、华南区成分为主。动物区系中华中、华南区成分的混杂现象也较明显,表现出在动物地理分布上的过渡性、渗透性。
