How is the main conflict in Island of the Blue Dolphins resolved?

The main conflict in this book is resolved through
Karana's resourcefulness and her courage.

The main conflict
in this book is the conflict between Karana and nature (and a few humans).  She is
trying to survive all alone on the island.  The only way that she can survive is by
being very brave and very clever.  For example, we see both of these qualities in her
interactions with the pack of dogs that kills her brother.  We see her bravery and
resourcefulness both as she devises and carries out a way to kill the dogs in revenge
for her brother's death.  It is also rather resourceful of her to tame Rontu to help
give her the sort of emotional support she needs to survive on her
own.

Through her resourcefulness and courage, Karana
survives this and many other dangers.  This is how the main conflict in the book is
resolved.
