Optimal foraging explains novel movement behavior of benthic diatoms

Wen-Si Hu, Ming-Ji Huang, H.P. Zhang, Feng Zhang, Wim Vyverman & Quan-Xing Liu
Adaptive locomotion of living organisms contributes to their competitive abilities and helps maintain their fitness in diverse environments. To date, however, our understanding of searching behavior and its ultimate cause remains poorly understood in ecology and biology. Here, we investigate motion patterns of biofilm-inhabiting marine raphid diatom Navicula arenaria var. rostellata in two-dimensional space. We report that individual Navicula cells display a “circular-run-and-reversal” movement behavior at different concentrations of dissolved silicic acid (dSi). We show...
