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.

Sunlight can't reach past roughly 1,000 meters because light attenuates as the water column absorbs and scatters photons, so deeper ocean layers remain in permanent darkness.

Longstanding Indigenous stewardship represents systematic, long-term empirical knowledge because sustained practices of reciprocity and resource management reflect repeated observation and feedback-driven strategies that effectively managed ecosystems over millennia.

With advanced vocal learning circuits, corvids map arbitrary sounds to environmental referents and can imitate human words, allowing them to convey information or manipulate social contexts through mimicry.

If you shaved off all land and dumped that volume into the ocean basins, the added material would fill low regions and produce a global ocean roughly two miles deep, illustrating how land volume compares to basin capacity.

When a bird associates a person with threat it emits scolding displays that others observe and copy, causing avoidance and targeted scolding of that human to spread socially and persist across individuals and generations.

Hydrostatic pressure increases with the weight of the water column, so at hadal depths (around 6,000 meters and below) pressures reach roughly 1,100 times surface pressure, producing crushing forces that would destroy unprotected objects or organisms.

Their ability to recognize individuals, form associations, and socially transmit information lets corvids exploit human-provided resources and avoid threats, which increases survival and reproduction in human-dominated habitats.
