    • The branching pattern observed in Figure 1 shows that the early eutherian radiation was rather rapid (note the short basal internodes coupled with long terminal branches).
    • The articulated colonies of Crisia fragment into their constituent internodes after decay of the elastic joints.
    • Genotypic selection analysis revealed strong density-dependent selection in the open site, favoring genotypes with longer internodes at high density and with short internodes at low density.
    • We began by eliminating one internode, the fourth internode (the one closest to the t-junction), leaving other parameters unchanged.
    • In type II divergence, the evolutionary rate for a specific site is accelerated somewhere along the basal internode that connects the two subfamilies.
    1. 1.1Botany A part of a plant stem between two of the nodes from which leaves emerge.

      • The leaf is one component of the repeating vegetative segment or phytomer, comprised of the leaf, node, internode, and axillary bud.
    2. 1.2Anatomy A stretch of a nerve cell axon sheathed in myelin, between two nodes of Ranvier.
      〔剖〕结间部;节间部
      Example sentencesExamples
