Newly molted first stage juvenile crabs (C1) of the mud crab,Scylla paramamosain,were subjected to different temperature (14,20,26,32 and 39℃),salinity (5,10,20,30 and 40‰),starvation and autotomy (for autotomy experiment,the second stage crabs (C2) were used) to assess their effects on molting success,molting interval and corresponding expression of ecdysone receptor (EcR) of the crabs.

对汕头近岸海域70个站位表层沉积物作了粒度分析和粒度参数计算,以探讨沉积物粒度分布特征.分析结果显示,研究区表层沉积物可划分为9种底质类型,以黏土质粉砂(YT)、砂质粉砂(ST)和砂-粉砂-黏土(S-T-Y)为主;砾、砂、粉砂和黏土的平均含量分别为1.4％,29.2％,51.0％,18.4％.平均粒径在0.12～7.30Ф之间变化,平均值为5.53Ф;分选系数、偏态和峰态值的变化范围分别为0.50
水下声探测是外国调查船和水下文物盗捞船进行非法调查和探测的主要技术手段,开展水下声探测信号的研究对非法调查的监视取证和水下文物保护具有重要意义.根据信号的主要声特征,对水下声探测信号进行分类,分为宽带中低频信号和窄带高频信号.出海采集了浅地层剖面信号、电火花声源信号、侧扫声纳信号和单频测深信号四种代表性的水下声探测信号,给出了对应的声特征分类.通过对四种实测声探测数据的分析研究,给出了对应类型的水
A Gram-stain positive,non-motile,rod-shaped bacterium,designated strain 1111S-42T,was isolated from the East Siberian Sea.The organism was found to grow at 4-30℃,pH 7.0-8.5 and in 0-8%(w/v) NaCl,with

本文通过西菲律宾海盆两个区域采集的表层沉积硅藻进行分析,其中,F01区59个表层沉积物样中,共鉴定出硅藻47种和变种,隶属于24属;F04区129个表层沉积物样中,共鉴定出硅藻39种和变种,隶属于17属.西菲律宾海盆硅藻总平均丰度为1111.5粒/g,其中F01区平均丰度为1848粒/g,F04区平均丰度为375粒/g.硅藻属种主要以外洋暖水种和广温种为主,其中Azpeitia nodulifer
采用单颗粒气溶胶质谱仪(SPAMS)对厦门岛南部近岸大气气溶胶颗粒进行了实时在线分析,获得了大气气溶胶颗粒的粒径和化学组成的谱分布特性,并对大气气溶胶的浓度、组成及其来源进行了分析.结果表明:厦门近海大气气溶胶在测量范围内呈单峰分布,峰值粒径在0.6m左右,且主要为亚微米级颗粒物;气溶胶中含NOx-、HSO4-、Cl-、NH4+和Na+等的颗粒数浓度具有明显的谱分布特性,含有NOx-、HSO4-和
贺兰山保护区岩羊(Pseudois nayaur)种群数量近年来增长很快,为了了解贺兰山保护区的岩羊种群的健康状况,从而更好的保护和管理岩羊种群,我们需要对岩羊种群的遗传多样性进行研究.我们在其近缘物种选出36对微卫星引物对收集到的岩羊粪便DNA样品进行PCR扩增.结果发现,有9对引物在岩羊粪便基因组DNA中扩增出了多态性位点.各位点基因杂合度介于0.26～0.95,平均杂合度为0.48,各位点多
2009年8月份采用静态箱法对珠江口淇澳岛湿地甲烷通量日变化进行测定,结果表明甲烷排放通量在当日23:00和翌日早晨9:00出现两个高峰值,分别为40.07mgm-2h-1和50.99mgm-2h-1;在当日17:00和翌日凌晨5:00出现两极小值,分别为1.13mg m-2h-1和1.57mg m-2h-1,同步观测孔隙水中SO42-、Cl-浓度和沉积物表层温度和采样点潮位变化,发现湿地甲烷排放
