Species,essence and explanation

Michael Devitt, 2008, Devitt, 2010 has argued that species have intrinsic essences. This paper rebuts Devitt’s arguments, but in so doing it shores up the anti-essentialist consensus in two ways that have more general interest. First, species membership can be explanatory even when species have no essences; that is, Tamsin’s membership of the tiger species can explain her stripyness, without this committing us to any further claim about essential properties of tigers. Second, even the views of species that appear most congenial to essentialism—namely phenetic and genotypic cluster accounts—do not entail strong forms of intrinsic essentialism.     

水环境中活性氧的来源、种类及测定方法

各种环境介质和生命体中许多微观化学过程都与活性氧密切相关.本文介绍了水环境中活性氧的来源、种类和测定.它们主要包括:¹O₂(单线态氧)、O₂^-(超氧自由基)/HO₂·(氢过氧自由基)、·OH(羟基自由基)、H₂O₂、RO·(烷氧基)、ROO·(烷过氧基)和R·OH(氢过氧化物)等.其主要来源于辐射分解、热解和氧化还原法等.测定采用分子探针法、图谱法和酶法.     

Xiphinema krugi,Species Complex or Complex of Cryptic Species?

Fourteen morphologically putative populations of X. krugi were clearly separated into four different profiles by RFLP analysis (Alu I and Hinf I), sequencing of the ITS-1 region, and subsequent Maximum Likelihood phylogenetic analyses. These four profiles were further supported by a principal component analysis of morphometric characters that yielded four taxonomic clusters matching those produced by the molecular data. Sequence homology was greater amongst populations that represented the same RFLP profile than between profiles and similar both between representative populations of the RFLP profiles and putative closely related Xiphinema species. This study suggests that X. krugi is a potential species complex comprised of at least four distinct genotypes.     

贵州分布长肢林蛙种组物种一新记录——徂徕林蛙

2018年5月,在贵州省黄平县朱家山县级自然保护区进行本底资源调查时采集到蛙属Rana物种标本10号,结合形态鉴定和分子系统学分析,确认该物种为徂徕林蛙Rana culaiensis,为贵州省两栖动物新记录。此次发现对于进一步认识徂徕林蛙的形态特征及地理分布格局具有重要意义。此次采集标本与模式产地标本在体型、趾间蹼等方面存在差异,这种差异是否为适应不同的地理环境而产生的形态变异,还有待采集符合统计学的标本数据来论证。
