BIO205H5 Lecture Notes - Lecture 7: 0 (Year), Grey Seal, Exponential Growth
Document Summary
We can develop models to describe these changes. Predicting population size is crucial for conservation planning. It"s very flat so hard to spot - can crash in inclement weather. Because all sand, it is very likely to shift and change position. About 5 people that live on it seasonally - 1 permanent and others part of studies. ~100 horses brought on the island - varies sometimes. Sliver of sand off the coast of nova scotia. Big population on sable island - extends onto nova scotia coats. The grey seal population is increasing on sable island. Number of pups increasing exponentially over the years since 1960. Started with incomplete tagging in 60"s-70"s, to complete tagging in 80"s-90"s and then aerial photographing in the 2000"s (flying over and taking pictures where you spot pups from adults differentiated by coloring - this is estimated) Develop model for what pop looks like now - we can estimate that there are more now.
