invasive species, energy, diet, season, latitude
The Asian shore crab, Hemigrapsus sanguineus , is an invasive crab species that lives on the East Coast of the United States. It has become an important part of its invaded ecosystems and their energetic interactions. We studied this species’ energetics to better understand how they vary across season and latitude.
- The ratio of gut width to carapace width (“standardized gut size”) is indicative of long term diet quality in crabs (a larger gut corresponds to a lower average diet quality) (Griffen & Mosblack 2011)
- We measured standardized gut size and gut energy content to examine how this species’ diet composition and energy intake vary across season and latitude
- Our research helps explain the dietary and energetic trends of the Asian shore crab and could be useful in predicting future invasion patterns and locations
