postnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Sedum Acre Embryogenesis: Polyploidization in the Suspensor
Cytological processes of differentiation in the embryo suspensor of Sedum acre L. were compared with the development of the embryo proper. The zygote undergoes an asymmetric division to produce an apical cell and a basal cell, which becomes the basal cell of the suspensor. The mature differentiated suspensor consists of a large haustorial basal cell and 3–4 chalazal cells. The basal cell nucleu...
