Question
**Understanding Owl and Wood Rat Population Dynamics**

Let's explore how the populations of owls and wood rats change over time using mathematical modeling. This will help us understand the interactions between these species and make predictions about their future numbers.

### Population Representation

We denote the populations of owls and wood rats at time \( k \) (measured in months) by:

\[ \mathbf{x_k} = \begin{bmatrix} O_k \\ R_k \end{bmatrix} \]

where:
- \( O_k \) is the number of owls,
- \( R_k \) is the number of rats (in thousands).

### Dynamical System Equations

The changes in the populations of owls and wood rats are given by the following equations:

\[ O_{k+1} = (0.20)O_k + (0.5)R_k \]
\[ R_{k+1} = (-0.16)O_k + (1.1)R_k \]

### Analyzing the System

These equations represent a dynamical system that shows how the population of owls and wood rats evolve over time. Our goal is to determine how \( \mathbf{x_k} \), the vector representing the populations, changes as time progresses.

### Unstable Equilibrium

The system tends toward what is called an unstable equilibrium. This implies that small changes in the population sizes or parameters of the model (such as birth rates or predation rates) can lead to significant variations in the overall dynamics of the populations.

### Formula for \(\mathbf{x_k}\)

To understand and predict future population sizes, we need a formula for \(\mathbf{x_k}\). Given the setup of our system, we can represent \(\mathbf{x_k}\) as a linear combination of two vectors:

\[ \mathbf{x_k} = c_1 \begin{bmatrix} \quad \quad \\\quad \\ \end{bmatrix} + c_2 \begin{bmatrix} \quad \quad \\\quad \\ \end{bmatrix} \]

(The specific vectors and constants \(c_1\) and \(c_2\) would be determined based on initial conditions and further analysis of the system such as eigenvalues and eigenvectors).

By following this step-by-step approach, we can analyze and interpret the population dynamics of owls and wood rats over time, and assess the impact of various changes on their populations.
