Fifteen krill species map the Benguela food web's nutritional architecture
Fifteen krill species map the Benguela food web's nutritional architecture, and the findings demand a recalibration of how we model these waters. Lantern shrimp are far more than a simple link between plankton and predators. Their species-specific diets, ranging from herbivory to exclusive carnivory, reveal a complex trophic tapestry. This empirical data, validated through stable isotope and fatty acid analysis, underscores the need for integrated food-web models.

Rapid PAH Assessment in Seabirds Reveals Contamination Risks.
A validated HPLC method now gives researchers a practical way to measure PAH contamination in seabird blood plasma, with limits of quantification comparable to recent studies. Applied to Brown boobies along the Rio de Janeiro coast, the approach revealed low-level exposure consistent with chronic background contamination rather than acute events. That distinction matters. The method's simplicity reduces handling risks and supports ongoing monitoring. For readers tracking related environmental health risks, our coverage of automated soil microplastic separation offers a complementary look at contaminant detection.
