This fortress, built by termites, is a triumph of cooperative engineering, featuring sturdy walls to repel enemies, deep dungeons for moisture gathering, and internal space for food storage and crop cultivation. At the core of this complex lies the queen, a monumental figure who produces a thousand eggs daily to sustain the army of masons and gardeners. She resides in a special chamber, a voluntary prisoner whose bulk eventually prevents her from moving or squeezing through the corridors built by the attentive workers. ...

In the semi-arid environments of the southern African savanna, where the termite Macrotermes michaelseni thrives, the colonies face thermal fluctuations far more severe than their shaded Asian counterparts. These African mounds operate in an environment characterized by direct sun exposure and large daily temperature swings, sometimes reaching up to a 20°C difference between high and low points. Furthermore, this habitat experiences strong external winds, averaging up to 5 m s⁻¹. ...

For decades, studying the functional principles of termite mounds, particularly the precise flow of air and gas, was hampered by the mound’s opaque and complex structure. Traditional visualization methods, such as casting the tunnels with plaster or physically sectioning the mound, are inherently destructive, offering only partial and non-reusable information. Furthermore, the complexity of internal structures, featuring a network of tunnels, chimneys, and pores, makes direct in situ flow measurement difficult and localized. ...
