The go-to data point used to indicate whether an institution is helping students reach success has tended to be its graduation rate. Post-graduation employment is another indicator but the definition of student success has evolved to include many more areas.
However, many examples exist of non-linear and sometimes abrupt changes in ecosystems. A change may be gradual until a particular pressure on the ecosystem reaches a threshold, at which point rapid shifts to a new state occur. Some non-linear changes can be very large and have substantial impacts on human well-being.
How do these alterations affect ecosystems on a larger scale? 3. What problems arise when a species is introduced from a foreign ecosystem and why do these problems occur? If a species is introduced to new environment, what factors determine whether the species will adapt to its new environment? Once introduced to a new environment, can a species undergo changes that eventually create a new species (speciation)? 4.
