Article Synopsis
- Marine bacteria can navigate towards large algal polysaccharides like laminarin and alginate, influencing interactions and nutrient cycling in marine ecosystems.
- Although bacteria typically respond to small metabolites, these polysaccharides showed an unexpectedly strong attraction compared to their smaller sugar constituents.
- Additionally, dimethylsulfoniopropionate (DMSP) enhances this attraction, suggesting it may aid bacteria in detecting polysaccharide gradients and play a significant ecological role in marine carbon cycling.

Predatory protozoa play an essential role in shaping microbial populations. Among these protozoa, are ubiquitous in the soil and aqueous environments inhabited by . Observations of predator-prey interactions between these two microorganisms revealed a predation strategy in which assemble in aggregates, termed backpacks, on their posterior.

Bottom-up trophic interaction chains induced by mammalian herbivores, particularly in invertebrate food webs, remain largely unexplored. We tested whether effects of mammalian herbivores on the vegetation ricochet back up several trophic levels of the invertebrate food web.
