Small population size
This is definitely wrong. Speciation is caused by two groups or more groups of the same species becoming separated into different environments. There both adapt to their own environment and become slightly different to each other. EG If one group of birds is carried to an island that only has long deep flowers to feed on. They will develop longer and narrower beaks to be able to gather the nectar.

An increase in temperature as altitude is increased.
A population becomes separated by different environments and do not reproduce with one another.
Sympatric speciation is the process through which new species evolve from a single, or are even identical, so that they occur together at least in some places.
A small, isolated population is more likely to change substantially enough to become a new species than a large one.

Factors such as geographic isolation, environmental changes, genetic mutations, and selective pressures can increase the rate of speciation by driving populations to evolve separate traits or behaviors that lead to reproductive isolation.
