Fish Eggs Turn Conventional View of Ocean Food Webs Upside Down

Fish Eggs Turn Conventional View of Ocean Food Webs Upside Down

Do you remember in fifth grade science class learning about food webs? Plants absorb energy from the sun, plants are eaten by animals, and smaller animals are eaten by bigger animals. Generally speaking, the flow is from smaller to larger organisms. An analysis by researchers at The University of Texas Marine Science Institute and the Florida Fish and Wildlife Research Institute reveals how the flow of nutrients in the ocean can also go in reverse, from larger animals to smaller ones. This new understanding has implications for conservation and fisheries management.

Changes in Coastal Upwelling Linked to Variability in Marine Ecosystem Off California

Changes in Coastal Upwelling Linked to Variability in Marine Ecosystem Off California

In findings of relevance to conservationists and the fishing industry, new research links short-term reductions in growth and reproduction of marine animals off the California coast to increasing variability in the strength of coastal upwelling currents — currents that supply nutrients to the region's diverse ecosystem.

Switching to a Power Stroke Enables a Tiny But Important Marine Crustacean to Survive

Switching to a Power Stroke Enables a Tiny But Important Marine Crustacean to Survive

Olympic swimmers aren’t the only ones who change their strokes to escape competitors. To escape from the jaws and claws of predators in cold, viscous water, marine copepods switch from a wave-like swimming stroke to big power strokes, a behavior that has now been revealed thanks to 3-D high-speed digital holography.
