Question

1. make a list of ecological consequences that you can infer have occurred on guam due to the introduction of the invasive (nonnative) brown tree snake.

Explanation:

The brown tree snake is an invasive species. Invasive species can disrupt ecosystems. They may prey on native species, reducing their populations. This can lead to a loss of biodiversity. Also, changes in the population of one species (due to predation by the snake) can have a ripple - effect through the food web. For example, if a native bird species (which is preyed on by the snake) declines, the plants that the bird pollinated or the insects that the bird ate may be affected.

Answer:

• Decline in native bird populations (as the snake preys on them).
• Loss of biodiversity (due to the decline of multiple native species affected by the snake's presence).
• Disruption of food webs (changes in predator - prey relationships and cascading effects on other species).
