 ==== Introduction ====
-Human activities have a high impact on ecosystems and understanding these impacts is crucial for conservation of species and ecosystems.
+Ecosystems are made of many interconnected biotic and abiotic components. A biotic component may be connected to another via an ecological interaction, such as predation, or it may be connected to an abiotic component, such as nitrogen soil content. Human activities that impact one of the components of an ecosystem can negatively affect a whole chain of interactions. McCauley //et al.// (2012) report on the breakdown of a long interaction chain linking diverse ecosystem components of a remote Pacific atoll.

 ===== Assignment =====
-Understand the dynamics occurring in the Pacific Atol system by simplifying its components and then compare it to the effects of human activities.
+Propose a mathematical model to describe the dynamics occurring in the Pacific atoll in simple but well-grounded way. Use this model to compare the dynamics of the undisturbed ecosystem with the dynamics that includes human-facilited coconut palm (//Cocos nucifera//) expansion.
 ===== Proposed Questions =====
-  *What are the minimal components of the Pacific Atol system needed to understand its dynamics?
+  *What are the minimal components of the Pacific atoll ecosystem needed to understand its dynamics?
-  *How does human activities influence the interaction chain found in the human-free Atol?
+  *Does human impact cause cascading effects through the interaction chain? Does it cause the loss of interactions?
