The Portulaca seeds died off. bradencouch24 https://padlet.com/bradencouch24/q4rbch5bjlnt/wish/442341843 2020-02-07 19:00:31 UTC https://padlet.com/bradencouch24/q4rbch5bjlnt/wish/442341843 Reasoning 1: Due to the drought the Portulaca seeds died off which where soft and easy to eat for the small beaked finch to eat. So when the seeds died off so did the small beaked finches. This resulted in an increase in larger beaked ground finch. bradencouch24 https://padlet.com/bradencouch24/q4rbch5bjlnt/wish/442342590 2020-02-07 19:01:44 UTC https://padlet.com/bradencouch24/q4rbch5bjlnt/wish/442342590 Natural Selection caused the beak of the ground finch population to increase on Daphne Major from from 1976 to 1978. bradencouch24 https://padlet.com/bradencouch24/q4rbch5bjlnt/wish/442343912 2020-02-07 19:03:58 UTC https://padlet.com/bradencouch24/q4rbch5bjlnt/wish/442343912 The population of small beaked ground finch decreased and died off. bradencouch24 https://padlet.com/bradencouch24/q4rbch5bjlnt/wish/442344408 2020-02-07 19:04:51 UTC https://padlet.com/bradencouch24/q4rbch5bjlnt/wish/442344408 Reasoning 2: Due to the drought when all Portulaca seeds died off the only seeds left were Tribulus seeds, which were hard to eat seeds which small beaked finches could not eat them. Tribulus seeds did not need as much water as the Portulaca seeds did which is why Tribulus seeds lasted longer and overall had more to eat. So the small beaked finch died off due to lack of food. bradencouch24 https://padlet.com/bradencouch24/q4rbch5bjlnt/wish/442344729 2020-02-07 19:05:19 UTC https://padlet.com/bradencouch24/q4rbch5bjlnt/wish/442344729 A trait of longer and larger beaked finch increased in length and/or depth. bradencouch24 https://padlet.com/bradencouch24/q4rbch5bjlnt/wish/442349487 2020-02-07 19:12:56 UTC https://padlet.com/bradencouch24/q4rbch5bjlnt/wish/442349487 Reasoning 3: When the smaller beaked finch died off because of the lack of food. This lead to an increase in larger beaked finch because they could eat the spiky Tribulus seeds. The average amount of Tribulus seeds during the drought in 1977 on Daphne Major was 8.3 tribulus seeds per square meter. bradencouch24 https://padlet.com/bradencouch24/q4rbch5bjlnt/wish/442349803 2020-02-07 19:13:29 UTC https://padlet.com/bradencouch24/q4rbch5bjlnt/wish/442349803
