Xin-Yu Fang et al.
In this study, hydrozoan medusae collected from a home aquarium in Sanming, China, were tentatively identified as Cladonema cf. californicum Hyman, 1947, based on DNA barcoding. Morphologically, these specimens differed from known Cladonema...
Intraspecific Variation in Responsiveness to Juvenile Hormone May Underlie Differences in Diapause Strategy Among Daphnia cf. pulex Clones [0.03%]
拟序哭水蚤(Daphnia.cf.pulex)不同株系滞育策略的差异与其对保幼激素反应可塑性有关
