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.
Many songbirds begin active incubation after laying their penultimate egg, resulting in synchronous hatching of the clutch except for a last-hatched individual ("runt") that hatches with a size deficit and competitive disadvantage to siblings when begging for food. However, climate change may elevate temperatures and cause environmental incubation as eggs are laid, resulting in asynchronous hatching and larger size hierarchies among siblings. Although previous work demonstrated that asynchronous hatching reduces nestling growth and survival relative to synchrony, the physiological mechanisms underlying these effects are unclear.

- HRMAS (high-resolution magic angle spinning) NMR spectroscopy improves the resolution of H and C NMR spectra in low-density polyethylene (LDPE) by allowing better visibility of molecular signals through swelling the polymer with solvents.* -
- The technique reduces anisotropic interactions that typically broaden signals, enabling a clearer understanding of the polymer's swelling behavior and the effectiveness of various solvents.* -
- HRMAS also demonstrates that the metallocene nickelocene can penetrate and disperse within the LDPE network without altering its structure, which aids future research into catalytic polymer degradation.*
This study identified restaurant manager/owner factors that may contribute to adoption of a restaurant-based healthy eating program, Eat Fit. Findings may be used to engage restaurants in efforts to increase access to and availability of healthy foods, promote healthy food choices, and work toward improving diet and lowering obesity and chronic disease risk in the community. .
