If you mention this model in a publication, we ask that you include these citations for the model itself and for the NetLogo software: This model is based on the NetLogo Flocking model. How does adding roads change the pattern of nest infection? CREDITS AND REFERENCES ![]() Press the ADD ANOTHER ROAD button to add a second road. HOW TO USE ITĬlick GO to start the parasites. Monitor windows count the number of nests, and the number of infected nests separately. Initil numbers of NESTERS and PARASITES are determined with sliders. Parasites will fly in a random pattern, but tend to stay close to the road. PARASITES are clustered on the edge of the forrest. The NESTERS are radnomly distributed through the forrest. The forrest is bordered by a brown road on each side. The black icons are NESTERS, their nests do not move. The red icons are PARASITES, parasites fly around the edge of the forrest, looking for nearby nests to lay eggs. When cuckoo eggs hatch, the chicks push nestmates out. Cuckoos lay eggs in the nests of other birds. The NEST PARASITES model simulates the ecology of European cuckoo birds. (For example, if you have multiple applets in differentĭirectories on the same web server, you may want to putĪ single copy of the NetLogoLite files in one central place andĬhange the archive= lines of all the HTML files to point In the HTML code to point to their actual locations. If the NetLogoLite files and your model are in differentĭirectories, you must modify the archive= and value= lines and ending with, and paste it into any HTMLįile you want. If you want, you can just take the HTML code beginning with ![]() You don't need to include everything in this file in your page. Though, so if it doesn't work from your hard drive, please try On some systems, you can test the applet locally on your computerīefore uploading it to a web server. (You can copy NetLogoLite.jar and įrom the directory where you installed NetLogo.) (NP.nlogo), and the files NetLogoLite.jar and In order for this to work, this file, your model file Windows and Linux users may obtain the latest Java from Mac users must have Mac OS X 10.4 or higher. Java must be enabled in your browser settings. Note that every time we create a new bug with the hatch primitive, we add the following command around brackets because if we do not add this code, our new turtle would have the exact same location, size, and direction with its parent turtle, making it virtually impossible for us to differentiate the two.This page was automatically generated by NetLogo 5.0.5. When a bug bumps into a patch of food while walking around randomly, it eats the food and then hatches a new bug. In the model example below, we have a turtle that represents a bug and some brown patches that represent food. For example, if your model has a penguins breed, you can use hatch-penguins and if you have an eggs breed, you can use hatch-eggs. You can use hatch for custom turtle breeds, too, by using the hatch-pluralbreedname convention.If you need your patches to create new turtles, you should use the sprout primitive. hatch can only be used by turtles within an ask statement.Similar to the create-turtles primitive, it takes a number and it also allows optional rules defined for the new turtles by following it with brackets. Hatch is a primitive that creates a provided number of identical copies of a turtle. ![]()
