Nitrogen from decaying salmon carcasses enters forest soils and is absorbed by mycorrhizal networks, which then redistribute that marine-derived nitrogen through tree-to-tree connections, linking ocean productivity to forest growth and health.

The hippocampus stores spatial and episodic memories, so incoming sensory information is interpreted in light of location and past events, producing decisions that reflect where the bird is and what it has experienced there before.

Because only about 5% of the seafloor has been accurately mapped, vast unmapped regions remain where deeper, undiscovered depressions could exist.

By looping sensory signals between the forebrain and thalamus instead of sending them straight to motor outputs, birds can re-evaluate impulses and modify intended movements before committing to action.

Vertical ocean overturning powers circulation because warm surface water is less dense and stays afloat while cooling and higher salinity increase density and cause deep water to sink.

Mother trees preferentially allocate more carbon to genetically related seedlings because they can direct resources through fungal links to kin, especially after injury, effectively passing support and fitness benefits down their genetic lineage.

Southeast trade winds push warm surface water into the Gulf of Mexico and, because Earth's rotation (the Coriolis effect) and prevailing westerlies deflect flows, that warmed water is channeled northeast toward Europe as the Gulf Stream.

Tight-knit human social networks create resilience because members exchange care, assistance, and emotional support when someone weakens, functioning analogously to how organisms exchange resources and signals in ecological networks to sustain the group.
