Tracing nutrient shifts through zooplankton after the Tajogaite eruption
Fifteen months after the Tajogaite eruption reshaped La Palma's coastline, the pelagic food web showed a striking resilience. By analyzing stable-isotope patterns across zooplankton size fractions, this study found that trophic structure was governed by size-based ecological organization, not localized volcanic forcing. The uniformity of δ³⁴S values across depths and seasons suggests marine production pathways remained intact.

Stable Isotope Analysis Reveals Dietary Links in Ocean Food Webs
Stable isotope analysis is transforming how we trace the movement of energy through ocean food webs. By examining the chemical signatures embedded in marine life, researchers can now map dietary links with remarkable precision. This study validates that approach, offering measurable evidence of how species interconnect beneath the surface. The findings reinforce a simple truth: understanding these relationships is essential to protecting the systems that sustain them.
Antarctic Plankton Food Webs: Blooming vs. Non-Blooming Trophic Dynamics
Phytoplankton underpin Antarctic food webs, yet the trophic pathways that sustain them remain unclear. This study of Potter Cove's plankton community compares blooming and non-blooming seasons, drawing on a 30-year time series to model interaction strengths. Bloom conditions supported more trophic species at higher levels, while microzooplankton proved vital for energy transfer when blooms were absent. That distinction matters. It sharpens our ability to predict how climate-driven shifts may ripple through polar ecosystems.
