The following species were collected from Karamik Lake in Afyon Province, Turkey between April and August, 2015, Hydryphantes flexiosus, Hydrodroma despiciens, Georgella helvatica, Eylais infundibulifera, Hygrobates nigromacutlatus and Torrenticola brevirostris. These species were separately analyzed by Ultraviolet Spectrophotometer (US) and the results assessed using graphical readings. The affiliations between the species were read from the graphical curves of each species and then compared in terms of the curves.展开更多

Water samples from Eber and Karamik Lakes were analyzed with ICP (ICP-OES Instrument Spectro Genesis Fee, Germany) equipment to determine the element levels in the water. That impact level of these elements on the distribution of species was discussed. Change in the lake water composition was not a significantly determining factor in the number of species and diversities of water mites. However, eutrophication was observed to be a determining factor on the distribution of species.展开更多

The total masses of these species were measured as mg with the use of an elemental analyzer to calculate the percentage of the organic components of their structures. The achieved values were assessed separately for each species and element with the interpolation method. Out of these organic elements, the amount of C with an approximately value of 50% was the highest for all species while the amounts of S which was approximately 1% was determined as the lowest for almost all species. The observed values were discussed in terms of the systematic of water mites.展开更多

文摘记述了从我国浙江省淡水蚌中采到的蚌螨科Unionicolidae水螨1新种,壮肢蚌螨Unionicola(Anodontinatax) ischyropalpus sp.nov.,模式标本保存于南昌大学生物科学工程系。壮肢蚌螨Unionicola(Anodontinatax) ischyropalpus sp.nov.Wen and Zhu(图1～6)正模♀,副模6♀♀,浙江太湖(30°56′～31°34′N,119°54′～120°36′E),2004-03-27,胡宝庆采自椭圆背角无齿蚌Anodonta woodiana elliptica(Lea)。种名词源:ischyr-,拉丁词,意思为"强壮的",palpus,拉丁词,意思为"触须、须肢"。指本新种具有强壮的须肢。鉴别特征:新种以后基节群内缘呈弧形(其它种的后基节群内缘皆接近为直角形)、粗壮的P-Ⅱ和P-Ⅳ(其它种的P-Ⅱ、尤其P-Ⅳ不膨大)特征显著区别于本亚属的其它已知种。
