Insight by Nature
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.
Every card on Korva is an insight someone saved from a podcast or video they loved.

See all →Ocean currents shape large-scale weather and climate because they carry warm water and the heat it contains from the equator toward the poles, redistributing solar energy and altering atmospheric temperature patterns.
Ecosystem resilience emerges from many species interactions because those interactions create feedbacks and cycles (like nutrient cycling and predation) that sustain function; removing key parts can break feedbacks and flip the system into degraded, hard-to-reverse stable states.
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.
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.
Large-scale polar melt can weaken or halt North Atlantic deepwater formation because the influx of fresh meltwater lowers surface salinity and density, preventing the sinking that drives the overturning circulation and its heat transport.
The amygdala produces immediate emotional threat responses to dangerous people while the hippocampus encodes the contextual and spatial details of those encounters, separating emotional reaction from episodic memory.
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.
On islands lacking woodpeckers, abundant prey hidden under bark and soil creates an exploitable niche, so individual crows that probe or fashion sticks gain food access and natural selection or cultural transmission stabilizes tool-making behavior.
