We experimentally studied anti-predator behaviors of tadpoles of Rana daunchina to Red swamp crayfishes (Procambrus clarkii), a potential invasive species of lowland of Emei Mountain.
<正> 本文以峨眉山的仙姑弹琴蛙(Rano daunchina Chang)蝌蚪作为猎物,该地区潜在的入侵物种克氏原螯虾(Procambrus clarkii)为捕食者,于冬季实验考察仙姑弹琴蛙蝌蚪对陌生入侵捕食者的反捕
A New Amphibian Record in Hubei Province, China: Hyiarana daunchina;
湖北省两栖类种的新记录——仙琴水蛙
Micronucleus and nucleus anomalies of erythrocytes of Rana adenopleura tadpoles were detected and observed in control (CK-), DMSO cosolvent (CK+), atrazine 0.
1mg/L(ρ2)、1mg/L(ρ3)和10mg/L(ρ4)溶液中弹琴蛙(Ranaadenopleura)蝌蚪血红细胞微核和核异常细胞数。
The behavior pattern of Rana adenopleura tadpoles exposed to the herbicide Atrazine(ρ 1～4/mg L -1:5, 10, 15, 20)was studied.
研究了不同条件下阿特拉津溶液中 (ρ1～ 4/mgL-1:5 ,10 ,15 ,2 0 )弹琴蛙 (Ranaadenopleura)蝌蚪的行为 ,运用方差分析 (ANOVA)检验了蝌蚪在不同浓度的阿特拉津、时间段、pH值、溶氧量等条件下的行为差异性 。
The micro-spatial distribution pattern of Rana adenopleura tadpoles ( at stages 25 and 26) exposed to herbicide Atrazine (ρ1-3/mg L-1 :10,20,30) was studied in an aquarium (l×b×h=40 cm×20 cm × 25 cm) by diffusion coefficient (one of five indexes) , and the tadpoles appear gathering.
采用扩散系数C等5种分布型指标测定阿特拉津溶液中(ρ1-3/mg L-1:10,20,30)弹琴蛙(Rana adenopleura)蝌蚪(均处于25期和26期,体长范围26-60 mm)在水族箱(l×b×h=40 cm×20 cm×25 cm)中的空间分布模式,结果表明蝌蚪在水族箱中为聚集分布。
