毛腿鼠耳蝠的核型、G-带和C-带研究

使用肺、心脏等进行组织培养,用空气干燥法制作染色体标本,对毛腿鼠耳蝠(Myotis fim briatus)进行核型、G-带和C-带型分析:毛腿鼠耳蝠2n=44,有3对大型中着丝粒染色体,一对小型中着丝粒染色体,染色体总臂数(N.F)为52;常规核型和G-带核型与已发表的该属中华鼠耳蝠(M.chinensis)、西南鼠耳蝠(M.altarium)等物种一致,说明了该属动物核型具有相当的稳定性;C-带核型有丰富的端位C-带,具有一定的特殊性。     

鼠耳蝠下丘听神经元对超声刺激的反应特性

实验在５只鼠耳蜗上进行，共观察了２２７个对超声刺激发生反应的下丘听神经元。这些神经元听反应的最佳频率在１４．３－７６．２ｋＨｚ之间；潜伏期在３．０－１２．０毫秒之间，多数神经元（７９．３％）为５．０－７．０毫秒；最低阈值位于－２０．０－７０．０ｄＢ ＳＰＬ之间；多数神经元（８２．０５％）的调谐曲线为宽阔型，少数（１７．９５％）为狭窄型；反应最佳频率沿下丘背腹轴呈明显有序地排列。     

毛腿鼠耳蝠Myotis fimbriatus不同组织酯酶同工酶的比较

采用聚丙烯酰胺不连续凝胶垂直板活性电泳,分析了毛腿鼠耳蝠的心脏、肝脏、肾脏、胸肌、肺、胃、小肠、舌8种组织的酯酶.结果表明:毛腿鼠耳蝠8种组织的酯酶同工酶存在差异,其分布和活性具有明显的组织特异性,与器官或组织所执行的功能有关.     

西南鼠耳蝠湖南分布新纪录

2007年1月至2010年1月,对湖南省湘西土家族苗族自治州吉首市寨阳乡堂乐洞、矮寨镇四方洞,和龙山县火岩乡飞虎洞进行了洞穴蝙蝠调查,共捕获鼠耳蝠标本7个,经鉴定为湖南省翼手目新纪录--西南鼠耳蝠Myotis altarium.     

大足蝠八种组织乳酸脱氢酶（LDH）同工酶比较研究

本文用聚丙烯酰胺不连续凝胶盘电泳,对大足蝠8种组织的LDH同工酶进行了报道。大足蝠心肌、肾、脑、血清、睾丸、胸肌、大腿肌组织的LDH同工酶的5条主带,以H亚基的活性最高,肝组织的5条主带以M亚基的活性最高。值得注意的是,在血清的谱带中,在LDH_3和LDH_4之间,出现了一条额外的LDH_e带,在心肌、肝LDH中,还分别出现了一条向阳极泳动比LDH_1还快的带,暂称为LDH_0带。     

毛腿鼠耳蝠回声定位声波的分析

毛腿鼠耳幅(Myotis fimbriatus)为中国特有编幅、在飞行及悬挂状态下发出的回声定位叫声为调频声．叫声主要包括2个谐波，其中第1谐波较强，飞行时第1谐波调频范围为39—93kHz，第2谐波调频范围为70—122kHz；叫声的持续时间10．6ms．结合回声定位叫声的声波特点分析，推断毛腿鼠耳幅多生活于阴暗潮湿、通风良好的山洞中，飞行速度轻侵，灵活性较差；多在树林的边缘或上空、农田、草地或水面上等不太复杂的近距离环境中捕食，捕食方式可能为空中捕食或掠食，捕食对象是中等大小的静止猎物，主要是双翅目的昆虫．     

Echolocation calls ofMyotis frater (Chiroptera: Hipposideridae) during search flight

Echolocation calls ofMyotis frater emitted during the search phase consist of brief frequency-modulated pulses. The sound signals are comprised of three harmonics of which the first one is of the highest intensity and occurs in all echolocation calls. The frequency of this fundamental harmonic ranges from 110.8 to 50.2 kHz, and its duration is about 3.5 ms. The second and the third harmonics are relatively weak, occurring in 50.0% and 25.0% of echolocation calls respectively, with frequencies ranging from 138.4 to 116.6 kHz for the second harmonic and from 193.6 to 170.8 kHz for the third harmonic. We presume that, according to the echolocation call features,Myotis frater probably forages the insects on the ground of complex environments.     

四川蝙蝠核型的进一步研究

报道了含中国特有种大足鼠耳蝠(Myotis ricketti)在内的、四川地区6种蝙蝠的核型.菊头蝠科2种,即大耳菊头蝠(Rhinolophus macrotis),核型为2n=62,FN=60;云南菊头蝠(R.yunanensis),核型较为特殊,2n=46,FN=58.蹄蝠科1种,即普氏蹄蝠(Hipposideros pratti),核型为2n=32,FN=60;蝙蝠科鼠耳蝠属3种,即中华鼠耳蝠(Myotis chinensis),核型为2n=44,FN=50;大足鼠耳蝠为2n=44,FN=52;西南鼠耳蝠(M.altarium)为2n=44,FN=50.其中云南菊头蝠的核型为中国第1次报道.     

西南鼠耳蝠7种组织乳酸脱氢酶(LDH)同工酶的比较

采用聚丙烯酰胺不连续凝胶垂直板电泳和日本岛津CS9000双波长薄层扫描仪,研究了西南鼠耳蝠7种组织的乳酸脱氢酶同工酶（LDH）,结果表明：西南鼠耳蝠7种组织LDH同工酶谱有较大的差异,其分布和含量具有组织特异性。
