In older bird guides, the audubon warbler and the myrtle warbler were classified as two separate species. for many decades, the two species lived side by side within their habitat range. in more current bird guides they are classified as eastern and western forms of the same bird species.
since the two warblers are now classified as different forms of one species, they must
a) now occupy the same niche.
b) be identical in appearance.
c) be able to successfully interbreed.
d) consistently live in the same geographic range.

How do temperature and salinity affect deepwater currents? question 15 options: as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
