Although extensively used for biophysical studies, the squid giant axon system remains largely unexplored in regard to in vivo function and modulation in any biologically relevant context. Here we show that successful establishment of the recruitment pattern for the giant axon in the escape response elicited by a brief electrical stimulus depends on prey-capture experience early in life. Juveni...

In this review, we summarize the energetic and physiological correlates of prey handling and ingestion in lizards and snakes. There were marked differences in the magnitude of aerobic metabolism during prey handling and ingestion between these two groups, although they show a similar pattern of variation as a function of relative prey mass. For lizards, the magnitude of aerobic metabolism durin...

The dynamics of a predator-prey system, where the predator has two stages, a juvenile stage and a mature stage, are modelled by a system of three ordinary differential equations. The mature predators prey on the juvenile predators in addition to the prey. If the mortality rate of juveniles is low and/or the recruitment rate to the mature population is high, then there is a stable equilibrium wi...

It is well known that biological pattern formation the Turing mechanism, in which a homogeneous steady state destabilized by addition of diffusion, though it stable kinetic ODEs. However, states are unstable ODEs rarely mentioned. This paper concerns reaction diffusion advection system under Neumann boundary conditions, where Our results provide stabilization strategy for same state, combinatio...

We present a discrete-time predator–prey model in which the prey population is assumed to evolve response toxicant. incorporate frequency-dependent selection into evolution, assuming that an individual's susceptibility predation depends on both trait it possesses and traits of others population. When symmetric, we show equation unable track changes fitness landscape, is, landscape may change wh...

In this paper, the prey-predator model of five compartments is constructed with treatment given to infected prey and predator. We took predation incidence rates as functional response type II, disease transmission follow simple kinetic mass action function. The positivity, boundedness, existence solution are established checked. Equilibrium points models identified, local stability analyses tri...
