1. Problems With Sea Turtle Extinction By Alex Baker

2.  6 of the 7 sea turtles species are on the endangered species list  Turtles are dying from entanglement in fishing lines, poaching, coastal development, pollution and global warming Problem

4.  Null: no outside factors are affecting sea turtle populations; they are just naturally dying out  Hypo 1: human factors are causing the high mortality rates of turtles  Hypo 2: environmental factors are causing the high mortality rates of sea turtles Hypotheses

5.  Random sampling  Longitudinal study  Experimental  Caught 100 turtles and attached tracking devices  Found 2 nests and set up cameras to observe  Control  Caught 100 turtles and took back to laboratory  Located 2 nests, collected eggs and took back to lab Methods

6.  Found turtles that died  Examined to find cause of death  After one year mark, tracked down other turtles to make sure they were still alive  Observed hatchlings from experimental and control nests  Released turtles from lab Methods continued

11.  Many turtles died from human factors  Mainly from commercial fishing and pollution  Results correspond to hypothesis 1  Null hypothesis can be rejected Discussion

12.  Paraiba, Brazil – turtles were dying from ingestion of plastic debris and net entanglement (Mascarhenas, 2004)  Hawaii – turtles were dying from commercial fishing (Work, 2010)  Show the same results - turtles are dying from manmade causes! Other studies
