Predator-Prey Interactions Between Crabs and Gastropods
Explore the complex dynamics of predator-prey interactions between crabs and gastropods in this 41-minute lecture by Dr. Kristina Barclay from the University of Alberta. Delve into the effects of ocean acidification and climate change on these relationships, both in modern ecosystems and throughout the fossil record. Learn about repair scars as indirect evidence of predation, their advantages and challenges in studying historical predation patterns, and the specific case study of the Cancer productus red rock crab. Examine how ocean acidification impacts prey defenses, including shell growth, strength, and structure. Investigate methods for interpreting ocean acidification in the fossil record and comparing repair scar patterns across different time periods and geographical locations. Gain insights into the implications of these findings for paleontology and our understanding of predation through time.
