We study a second-order difference equation of the form zn+1=znF(zn-1)+h, where both F(z) and zF(z) are decreasing. We consider a set of invariant curves at h=1 and use it to characterize the behaviour of solutions when h>1 and when 01 is related to

We consider discrete models of the form xn+1=xnf(xn−1)+hn, where hn is a nonnegative p-periodic sequence representing stocking in the population, and investigate their dynamics. Under certain conditions on the recruitment function f(x), we give a c

We investigate the effect of constant and periodic harvesting on the Beverton-Holt model in a periodically fluctuating environment. We show that in a periodically fluctuating environment, periodic harvesting gives a better maximum sustainable yield c

The change of behaviors of prey in the form of vigilance significantly affects the dynamics of a predator-prey system. In this paper, we consider a discrete-time predator-prey model, where the vigilance of prey acts as a trade-off between the safety

In this paper, we study a general discrete-time model representing the dynamics of a contest competition species with constant effort exploitation. In particular, we consider the difference equation xn+1=xnf(xn−k)−hxn where h>0, k∈{0,1}, and th

We consider the general second order difference equation $x_{n+1}=F(x_n,x_{n-1})$ in which $F$ is continuous and of mixed monotonicity in its arguments. In equations with negative terms, a persistent set can be a proper subset of the positive orthant

Consider a p-periodic difference equation x n + 1 = f n ( x n ) with a global attractor. How does a permutation [ f σ ( p − 1 ) , … , f σ ( 1 ) , f σ ( 0 ) ] of the maps affect the global attractor? In this paper, we limit this general questio

Given a p-periodic difference equation x n + 1 = f n mod p ( x n ) , where each f j is a continuous interval map, j = 0 , 1 , … , p − 1 , we discuss the notion of folding and unfolding related to this type of non-autonomous equations. It is possi
