Question 1

What ecological traits do successful invasive species possess? How do these traits interact to make controlling them difficult?

Accepted Answer

Invasive species possess high fecundity,

Question 2

Read the following scenario and answer the question below
Human activities, including fossil fuel combustion, farming, and deforestation, are known to increase the levels of carbon dioxide, methane, and nitrous oxides in our atmosphere. Measurable warming of Earth due to these greenhouse gases can alter ecosystem dynamics. In addition to the direct climatic effects on organisms within biomes, warming can lower levels of sea ice and increase precipitation in Arctic areas. Global warming also can melt permafrost in the tundra and increase sea surface temperatures, which could increase the intensity of hurricanes in vulnerable areas. Within communities, climatic change can shift interdependent species "out of sync," potentially causing indirect loss of species. For example, if pollinators and the plants they pollinate become out of synch, the pollinators may not be able to use a different food source, and the plants may not be able to reproduce.
