The aim of this work is to develop and analyse a mathematical model for a predator-2 preys system arising in insular environments. We are interested in the . A modified predator–prey model with transmissible disease in both the predator and prey species is proposed and analysed, with infected prey being more. Another model common in population biology, the predator–prey We model the dynamics of the police–gang relationship using a Serpents in the sand: essays on the nonlinear nature of politics and human destiny.
An important thing to realize is that as both organisms become faster to adapt to their environments, their relationship remains the same: This is true in all predator-prey relationships. Another example of predator-prey evolution is that of the Galapagos tortoise. Galapagos tortoises eat the branches of the cactus plants that grow on the Galapagos islands. On one of the islands, where long-necked tortoises live, the branches are higher off the ground.
On another island, where short-necked tortoises live, the branches are lower down.
Also, they play an important role in keeping the delicate balance of the ecosystem by controlling the population of the species they prey upon. Films — Animated The Aristocats: Scat Cat and his Alley Cats were going to eat Roquefort the mouse, but they are all portrayed as friendly, heroic and whimsical - cats eating mice is just the way things are. Coincides with Scavengers Are Scumas hyenas are portrayed as greedy, cowardly and having no respect towards the Circle of Life even though in Real Lifeboth hyenas and lions are predators that hunt for prey as well as eat carrion.
In Ice Agethe pack of sabretooth cats are the villains because they hunt humans not for food but out of revenge. Also, Manfred the mammoth berates the two brontotheres for trying to kill Sid the sloth despite being herbivores. You know, I don't like animals that kill for pleasure.

Pixar 's Finding Nemo has Marlin and Dory almost swallowed by a whale. The whale was trying to ingest a school of frightened krill; Marlin and Dory happened to be on the pursuit trajectory at the time.Predator prey cycle - Ecology - Khan Academy
As Dory points out: Also, Nigel the pelican may be a fish-eater, but he helps Marlin and protects him from seagulls after learning that he's Nemo's father looking for his son. Other predators are either portrayed monstrous the barracuda, the anglerfish or struggling with their Horror Hunger the sharks. In the sequel, Finding Dorywhen Marlin and Nemo encounter a duo of sea lions, Marlin claims that they are vicious predators, but as they are lazy and not hungry, they don't hurt the two fish and even give them some useful advice.
Dory also ends up in a bucket of dead fish that are meant to be the food of Destiny the whale shark, but after Destiny is revealed to be Dory's childhood friend, this gets forgotten.

The giant bioluminescent squid, on the other hand, is a monstrous Super-Persistent Predator. In Vuk the Little Foxthe protagonist is a fox who hunts other animals.
Although the prey animals are also portrayed as capable of emotions and speech, at no point is his predatory behavior seen as villainous.

The TarbosaurusSpeckles and his family are all predators, and hunting is presented as something they do for a living. The villain, One-Eye the Tyrannosaurus rexis not evil because he's a carnivore, but because he's a cunning, calculating sadist who wants to destroy his fellow predators.
Agent-based models are popular in investigating the spatio-temporal dynamics of crime. An interesting development in agent-based modelling is the incorporation of information from geographical information systems GISs so as to make the model more realistic. Generally, in applying these models to crime and criminal behaviour, the agents represent people—criminals, potential victims, police, etc. These agents inhabit an artificial environment that is designed to reflect features such as buildings, a street network, a social network, or barriers to movement.
The social nature of some types of crime and criminal behaviour is the basis of models adapted from population biology such as infectious disease models and predator—prey models, both of which deal with interacting groups.
The model developed in this paper examines the police—gang relationship where police officers act as predators of gang members and may become corrupted by them resulting in criminal behaviour on their part.
We model the dynamics of the police—gang relationship using a combination of an infectious disease and a predator—prey model from population biology also known as an eco-epidemiological model. The behaviour of the model is investigated through stability and bifurcation analysis. The paper is organized as follows: Material and methods 2. The mathematical model The model uses the analogy of police officers as predators of gang members.
Also, gang membership is treated as an infection that is spread to police officers by both gang members and other police officers.
