Microbial community diversity and heterotrophic production in a coastalArctic ecosystem: A stamukhi lake and its source waters
Microbial community diversity heterotrophic production coastalArctic ecosystem stamukhi lake source waters
2014/4/21
Stamukhi lakes are vast but little-explored Arctic ecosystems. They occur throughout winter, spring, and early summer near large river inflows along the Arctic coastline, and are the result of freshwa...
A bush, not a tree: The extraordinary diversity of cold-water basal foraminiferans extends to warm-water environments
A bush not a tree extraordinary diversity cold-water basal foraminiferans extends warm-water environments
2014/4/18
Foraminiferal species distribution and richness have traditionally been assessed through examination of the shells (tests) built by most of the described species, but molecular surveys indicate that t...

We analyzed the relationship between population abundance and cell size in phytoplankton assemblages from coastal, shelf, and open-ocean environments. Our results show that across the entire size spec...
摘要研究松属遗传多样性的方法涉及表型、同工酶、染色体、DNA等多层面。 松树表型性状变异广泛,其不同树种不同性状的遗传力(或遗传率)均存在差异。到目前为止,同工酶仍是检测松树遗传多样性的最常用方法,一般而言,松属树种群体内等位酶多样性程度高,群体间分化较低,但各树种的情形也不尽相同。松属树种染色体水平的变异很低,其核型高度一致。核DNA组较一般阔叶树大,遗传多样性丰富,但叶绿体等质体DNA则多样性...
小鼠H2Eb位点的PCR-SSP检测与多态性Genetic Diversity Examination of Murine H2Eb by PCR-SSP
H2复合体 PCR-SSP 等位基因
2008/1/16
摘要为探讨小鼠遗传背景的多态性,我们采用PCR-SSP技术对60只昆明种(KM)小鼠的H2Eb位点第二个外显子的等位基因进行鉴定,得到78个PCR阳性结果,共检出65%的等位基因且43.3%小鼠此位点的基因型相同。KM小鼠具有一定程度的遗传多态性。

不同地区库蚊复组群体的同工酶遗传多样性研究Genetic Diversity of Isoenzyme in Culex pipiens complex Field Populations Sampling from Distinct Area of China
库蚊复组 遗传多样性 工酶
2008/1/10
摘要采用水平切片淀粉凝胶电泳的方法,对分布于我国5省的8个库蚊复组(Culex pipiens complex)野生群体的遗传多样性进行研究,分析了4个酶系统7个基因座(ME、MDH-1、MDH-2、MDH-3、GPD、EST-2、EST-3)的酶谱资料。结果显示:(1)群体内存在不同程度的遗传变异(He为0.098~0.41);(2)较低的基因流水平(Nm=0.64)使遗传漂变起主要作用,造成群...

栓皮栎天然群体SSR遗传多样性研究Genetic Diversity of Microsatellites(SSRs)of Natural Populations of Quercus variabilis
栓皮栎 微卫星(SSR) 遗传多样性 遗传分化
2008/1/8
摘要
利用微卫星(SSR)标记对我国4个省内的5个栓皮栎(Quercus variabilis Bl.)天然群体的遗传多样性进行了研究。16对SSR标记揭示了栓皮栎丰富的遗传多样性:等位基因数(A)平均8.4375个,有效等位基因数(Ne)平均为5.9512个,平均期望杂合度(He)0.8059,Nei多样性指数(h)为0.8041。栓皮栎自然分布区中心地带的群体具有较高的遗传多样性,而人为对森...
饲养东北虎的微卫星变异研究Genetic Diversity of Microsatellite Loci in Captive Amur Tigers
东北虎 微卫星基因座 遗传变异
2008/1/8
摘要
东北虎是世界上濒危动物之一,具有极其重要的研究价值和保护意义。该研究利用10个在东北虎基因组中表现多态性的微卫星基因座(Fca005, Fca075, Fca094, Fca152, Fca161, Fca294, Pti002, Pti003, Pti007和Pti010)对113只饲养东北虎进行了遗传多样性检测。用非变性聚丙烯酰胺凝胶电泳检测微卫星的PCR扩增产物,计算了10个微卫星基...
