PPT-53 Population Ecology Lecture Presentation by

Nicole Tunbridge and Kathleen Fitzpatrick Turtle Tracks Population ecology explores how biotic and abiotic factors influence density distribution size and age structure of populations For example the number of loggerhead turtle hatchlings that survive their first journey to the ocean is affected by both biotic and abiotic factors.
