My research focuses on the relationship between habitat quality and squirrel population. The ideas that underpin my research is that squirrels will favour areas with greater number of fruit/nut trees. My research consists of counting the number of squirrels in each of the sample stations with regards to presence or absence of fruit/nut trees. I set up three sample stations and with the help of point count station method and systematic sampling strategy I recorded squirrel population in each station. My hypothesis touches on ecological processes of resource influence (presence or absence of fruit/nut tree) on species abundance (number of squirrels).
Keywords summarizing my research:
Species abundance
Resource influences
Seed predation
That is a good start, these are the ideas you will flesh out in detail in the introduction to your paper. You will want to touch on aspects of the alternative hypothesis which is whether there is evidence for other drivers of squirrel activity – is predation, territory defense etc. that might influence squirrel activity or if presence of high quality food is the most important.
