Benhadi-Marín, Jacinto; Pereira, José Alberto; Sousa, José Paulo; Santos, Sónia A. P. – Journal of Biological Education, 2020
Individual based models (IBMs) are up-to-date tools both in research and educational areas. Here we introduce an IBM built on NetLogo platform that simulates a top-down trophic cascade controlled by the pressure exerted by two model predators (web-building spiders and ground runner spiders) on a model pest (the olive fruit fly) within a…

Marques, M.; Arrabaca, J.; Chagas, I. – Journal of Biological Education, 2005
Leaves of higher terrestrial plants have small pores--stomata--responsible for gas exchange. The opening of each stoma results from the osmotic uptake of water by two specialised cells--the guard cells. Because of the involvement in this mechanism of ATPase-proton pumps and active transport of ions across membranes, we have designed an Exploring…
