"Fingerprints of climate change" refer to biological impacts of global warming on species that have already occurred over the last century. They are useful for understanding how species will continue to respond to current climate change trends. Of the examples below, which is not a biological fingerprint of climate change discussed in class?

The question asks us to identify which option is NOT a biological fingerprint of climate change discussed in class, among a list of potential ecological responses.
Option 1: 'Spring flowering plant flowering earlier in the spring in temperate forests.' This is a classic phenological shift driven by warming temperatures, representing a well-documented biological fingerprint of climate change.
Option 2: 'The spread of the Ebola virus from rural to high density, urban environments.' While disease dynamics can be affected by climate and environmental changes, the spread of Ebola is not typically categorized as a direct biological fingerprint of climate change in the context of species responses. It involves complex epidemiology, host dynamics, and socio-economic factors that extend beyond the standard ecological fingerprints used to illustrate climate-driven biological shifts.
Option 3: 'Migratory birds migrating to higher latitudes.' A poleward or elevational shift in migration patterns is a widely discussed response to warming and changing seasonality, fitting the concept of a biological fingerprint.
Option 4: 'The center range of red maple moving north in Minnesota.' A northward shift in species’ range is a textbook example of climate-driven distribution changes, another clear biological fingerprint.
Option 5: 'The distribution of alpine plant species shifting to higher elevation.' Elevational shifts of alpine flora to cooler, higher habitats are commonly cited fingerprints of climate change impacts on ecosystems.
In summary, except for Option 2, all other options describe direct, well-cited biological responses to climate change (phenology, range shifts, and elevational movements). Therefore, Option 2 is the one that does not fit as a biological fingerprint discussed in class.
