Hi Shari
Reading your whale census reports over the years, it seems apparent that the arrival times of the whales does influence your data where you compare
numbers with the same time the previous year.
I also remember last year being a banner year for whales in the lagoon. Are you however recording an uptick in their population size when you take the
final tally at the end of each season? I would relay these reports to my students and encourage them to make the trip south and get a real whale
experience.
The reason I ask is because we are covering marine mammals my class and all the news we get up here is that the whale population has shown a dramatic
increase in size over the recent years, with this year being no exception. Yet these conclusions are based on comparison counts at intervals from
specific locations (like Dana Point, Palos Verdes, etc.) My students were wondering whether the "final counts" at the lagoons substantiate this data,
or if other factors (such as really calm conditions) give a false sense of a rapidly increasing population.
Any help with this question would be appreciated.
Thank you! |
