### Interesting examples of models [closed]

I am studying the general use of models in biology in terms of methodology, applications, usefulness etc, and I would really appreciate any recommendations of some specific examples of models from any ...

### If wolves (or foxes) are fitter than rabbits, why rabbits have not become extinct? [duplicate]

I do not pretend to "demolish" the Darwinian theory of biological evolution and the "survival of the fittest", that's far from my intention. I have this doubt because of the fact that humanity, as ...

### Can predator-prey relationship be an example of negative feedback?

Predators eat their prey, prey population decreases. This results in the predator population to decrease, so less prey are consumed which causes the prey population to increase. Therefore, if the ...

### How to give a biological interpretation to this phase portrait?

Consider the following system and analyze its behavior. \begin{array}{rl} \frac{dA}{dt} &= A \left( 2-\frac{A}{5000}-\frac{L}{100} \right)\\ \frac{dL}{dt} &= L \left(-\frac{1}{2}+\frac{A}{...

### Replicator dynamics giving probabilities greater than 1?

I have a linear replicator equation and I want to simulate its dynamics to find the resting point and hopefully the Nash equilibrium. I defined strategies' payoff as $\vec f = C*\vec p+ \vec b$, ...

### Wasn't extinction of dinosaurs necessary? [closed]

Beginning from the triassic era, dinosaurs crawled for millions of years. So my basic idea is, that had the dinosaurs not been wiped out, they would have eaten all the flora on the planet then. ...

### References concerning the relative population sizes of predator and prey

In an ecosystem, say there are two species in a predator-prey relationship. What is the most typical ratio of these species' population densities? For instance, it could be that for every fox, there ...

### How can a species switch from r to K - reproductive strategy in a single generation?

I ask because it seems as though humanity is in the midst of doing exactly this. Only a few decades ago, human population was growing exponentially, and it seemed destined to keep growing until ...

### What was the first piece of work in computational biology?

What was the first piece of work in computational biology? I'm ideally looking for a paper. I am not interested in works that involve data management or data analysis but work that model biological ...

### Does an increased reproduction/mortality rate provide an evolutionary advantage?

If a species has a high mortality/birth rate, then it is able to adapt to changing environments more quickly than species that live for a long time. Without a high mortality rate, food and other ...

### Exponential growth equation and bacteria

I'm a microbiologist, but I'm teaching some ecology in my intro-level course, so when we got to population growth, I thought I'd use the example of a microbial population. But, I hit a strange problem ...

### Guide to learning about Population biology / ecology / dynamics for a non-Biologist

I'm an applied mathematician who works in the field of feedback control systems but has been becoming interested in looking at population biology (e.g. Lotka-Volterra, Mathusian growth,etc.) from a ...

### Why haven't prey evolved the ability to always outrun their predators?

I can understand why some prey can't outrun a recently evolved species. However, since cheetahs have existed for so long, why haven't its prey evolved to always outrun it, driving cheetahs to ...
