A dynamic model is proposed in order to simulate sandhopper (Talitrus saltator) population dynamics under various scenarios. It was built under the Stella simulation software and so far it has attained the calibration and verification stages. The basic structure of the model depends on the simulation of the number of animals in each age class (45 d...

... division would account for differences on the fertility of the females and would allow us to calculate the number of individuals in each age class, their average weight and the biomass of the entire population. Air temperature, lunar periodicity and day length are the main forcing functions for the model (Figure 1). The moisture content of the sand seems to affect only the spatial distribution of the animals and therefore it was not considered a relevant forcing function. ...

In this article, we firstly establish a nonlinear population dynamical model to describe the changes and interaction of the density of patient population of China's primary medical institutions (PHCIs) and hospitals in China's medical system. Next we get some sufficient conditions of existence of positive singularity by utilising homotopy invarianc...
