Vulture Population

In our class, Population, we chose an organism to study population on. We learned about geometric and arithmetic sequences and tried to see patterns in our chosen organisms population over time. I chose to compare cinereous vultures with humans, to see how they impact one another. Down below is a video I created about the relationship between cinereous vultures and humans.

CALCULATIONS

Population of cinereous vultures in 2018 : 2,000

The average # of eggs laid : 1

# of females of 2,000 : 1,250

% that mate : 25%

Chance of survival : 45%

2018 : 2,000

2017 : 1860

2,000 x .25 = 312.5

312.5 x .45 = 140.625

2,000 - 140.625 = 1,860

2016 : 1,651

1,860 x .25 = 465

465 x .45 = 210

1,860 - 210 = 1,651

2015 : 1,466

1,651 x .25 = 412.75

412.75 x .45 = 185.7375

1,651 - 185.7375 = 1,466

2014 : 1,302

1,466 x .25 = 366.5

366.5 x .45 = 164.925

1,466 - 164.925 = 1,302

2013 : 1,156

1,302 x .25 = 325.5

325.5 x .45 = 146.475

1,302 - 146.475 = 1,156

2012 : 1,026

1,156 x .25 = 289

289 x .45 = 130.05

1,156 - 130.05 = 1,026

2011 : 911

1,026 x .25 = 256.5

256.5 x .45 = 115.425

1,026 - 115.425 = 911

2010 : 809

911 x .25 =227.75

227.75 x .45 = 102.4875

911 - 102.4875 = 809

2009 : 718

809 x .25 = 202.25

202.25 x .45 = 91.0125

809 - 91.0125 = 718

2008 : 639

718 x .25 = 177

177 x .45 = 79.65

718 - 79.65 = 639
