Predator-Prey Interactions Between Crabs and Gastropods
Offered By: Royal Tyrrell Museum of Palaeontology via YouTube
Course Description
Overview
Syllabus
Intro
Exploring the past, present, and future of predator-prey interactions between crabs and their gastropod prey
Can we study predation through time!
Indirect Evidence: Repair Scars
Repair Scars: Advantages
Can we use repair scars to study predation through time?
Repair Scars: Challenges
Study System Cancer productus Red rock crab
Challenge #1: How does ocean acidification affect prey defenses?
Shell Growth
Shell Strength
Shell Structure Dissolution! Low pH
How do we interpret OA in the fossil record? • Change in size at which repair scars occur? • Look for asymmetrical effects on prey
How do we compare repair scars? Does A in # repairs
Size at Repair
A Success or #Attacks?
Latitudinal Repair Patterns?
Repairs through time?
Pleistocene More repairs
Implications for palaeontology?
Can we study predation through time?
