The Portulaca plant is the plant that died because of very little rainfall and it produced soft seeds, the Tribulus plant survived and it produced harder seeds. When all that was left was hard seeds the birds with the smaller, thinner beaks died because they couldn't eat the hard seeds and didn't have a food source but the birds with the bigger, thicker beaks could eat the harder seeds, had a food source, and survived. So when the birds with smaller beaks died the population decreased but then as the birds started to mate the population of the birds with bigger, thicker beaks increased because that was the only type of bird left on the island.

There was a drought on Daphne Major in 1977 and there was a very low food abundance for the animals living there. The Portulaca plant died and there was no more seeds from that plant available for the birds with smaller beaks on the island. The Tribulus plant somewhat survived through the drought and still produced a few seeds available for the birds with bigger beaks on the island. The drought caused the plant abundance to increase and decrease.

When there was very little rainfall in 1976 to 1978 some plants that provided food for different birds died because they didn't have enough water. This caused some birds to not have a food source and some to have a food source. This also caused a change in population and in characteristics of the birds because some could eat and some couldn't.

The population decreased but the average size and depth of the birds beaks increased over time.

The average Portulaca plant seed count decreased and the Tribulus plant seed count increased from 1976 to 1978.

The average rainfall on Daphne Major decreased which caused food to be scarce.

I think natural selection caused the Medium Ground Finch population on Daphne Major to increase in size from 1976 to 1978.
