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.
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.
