St.Kitts Rodent Recovery Day 56
Whew! It’s been a
long time since the last update but gee, there have been some significant
findings, that’s for sure. After trying 240 times to bring a Nevis Animal into
the St. Kitts population, I have determined that it mating them is not possible,
for there are several prezygotic reproductive barriers.
Upon closely inspecting the
courtship process of each animal, it is seen that there is an obvious
behavioral isolation – the rodents of St. Kitts have an average courtship
display that lasts approximately 12.6 seconds, whereas the Nevis rodents have a
courtship display that lasts 21.3 seconds! Due to the difference in the length
of each ritual, it seems that they are unable to attract each other.
Additionally, the
average measurements of the St. Kitts rodent, and the Nevis rodent were
obtained, and here are the results:
Though they have the
same body patterns and shape, these rodents vary slightly in size and physical ability. Thus, due to these reasons, it appears to be that the St. Kitts
Rodent and the Nevis Rodent are two different species.What a finding!
