The Flame Cell of Rotifer

The protonephridial systems of a number of metazoa consist, in part, of flame cells or flame bulbs which are specialized structures attached to paired collecting tubules. In rotifers, each tubule is said to bear two to eight (1) or more (2) flame bulbs. These structures are located in the pseu-docoelomic cavity and are believed to function in the control of osmotic pressure and, possibly, in th...

The Stomach Cell of Rotifer

Some details of the uhrastructure of the syncytial stomach cell of the rotifer have been presented by Lansing (1). He has described the luminal membrane of the stomach cell as consisting of a thick reticular layer beneath a unit membrane 60 A thick. He noted a similarity between this layer and the terminal web of the intestinal epithelium. Lansing further observed goblet-shaped pockets in the g...

Modeling the dynamics of inhomogeneous natural rotifer

Most population models assume that individuals within a given population are identical, that is, the fundamental role of variation is ignored. Here we develop a general approach to modeling heterogeneous populations with discrete evolutionary time step. The theory is applied to population dynamics of natural rotifer populations. We show that under particular conditions the behavior of the inhom...

Modeling the dynamics of natural rotifer populations:

A model of the dynamics of natural rotifer populations is described as a discrete nonlinear map depending on three parameters, which reflect characteristics of the population and environment. Model dynamics and their change by variation of these parameters were investigated by methods of bifurcation theory. A phase–parametric portrait of the model was constructed and domains of population persi...
