Article Synopsis
- Habitat partitioning allows brown and white shrimp to coexist by using estuarine habitats at different times, although they do overlap, particularly towards the end of their nursery residency.
- Laboratory experiments tested how the density and presence of each shrimp species impacted their growth and mortality rates.
- The study found that species identity influenced growth and survival, with smaller shrimp having higher mortality, indicating environmental changes could affect their populations in varying ways.
Article Synopsis
- Morphological traits can help predict the diet and trophic position of species, particularly in how gut size varies among closely related animals.
- Crabs with larger stomachs tend to be herbivorous or consume low-quality diets, and external markings on their carapaces correlate with gut size.
- The study found that these markings can be used as a non-lethal method to estimate dietary strategies in crabs, revealing insights into their evolution and morphological tradeoffs.
