Question

9. In a 13-year study of population dynamics of the invasive Asian shore crab (Hemigrapsus sanguineus) inLong Island Sound, Kraemer (2019) found that density declined over time, and the largest

size classes declined the most. At the same time, average size of breeding females also declined (see figures below).Based on your understanding of life-history strategies, develop a hypothesis that would explain this pattern.Explain the reasoning behind it in enough detail that another student would be able to understand it.
