Sample Research Papers:

Description: My sample subjects involved 24 swordtail fishes (12 large fish and 12 small fish). You will see LL and LS on the data ( LL is stand for large fishes and LS is stand for small fish). My group watched total 12 videos to record the data (we picked random 1 large fish vs. 1 small fish in each video, the video’s length is usually 15 minutes long but we only recorded fish’s behaviors within first ten minutes in each video.)

Scoresheet:
How long are you watching a certain male for? 10 Minutes
Which group is it from? LL or LS
Time that “LARGE MALE” is following a prospective female
Number of times the “LARGE MALE” touches the female
Number of times the “LARGE MALE” chases the female
Number of times the “LARGE MALE” mimics the female’s movement

Main Themes:
At first, We thought more behavior in LL because we thought in LS they might not do as much courting because no competition so females would “naturally” just go to them instead of the smaller male.

BUT WE FOUND THAT In LS, large male is less inhibited by another large male so more likely to go around and do other things to mate with female.

LL they are distracted with each other (fighting/dominance) as opposed to courting the female, so less activity here
