Patterns and rates of air movements in the mounds and nests of Macrotermes michaelseni were studied using tracer methods. Wind is a significant source of energy for powering nest ventilation, despite the mound being a completely enclosed structure. Nests are ventilated by a tidal movement of air driven by temporal variation in wind speed and wind direction. Density gradients sufficiently steep to drive bulk flow by natural convection will be rare. However, metabolism‐induced buoyant forces may… Expand
Termite mounds harness diurnal temperature oscillations for ventilation
TLDR
By directly measuring the flow inside a mound, it is shown that diurnal ambient temperature oscillations drive cyclic flows that flush out CO2 from the nest and ventilate the mound, demonstrating how work can be derived from the fluctuations of an intensive environmental parameter. Expand
Thermoregulation and ventilation of termite mounds

TLDR
Results from recent studies on Macrotermes bellicosus are reviewed that considered the interdependence of ambient temperature, thermoregulation, ventilation and mound architecture, and that question some of the fundamental paradigms of termite mounds. Expand
Transient-state mechanisms of wind-induced burrow ventilation
TLDR
It is proposed that consideration of the physiological ecology and evolution of the burrowing habit has been blinkered by the long neglect of AC ventilation. Expand
Solar-powered ventilation of African termite mounds
TLDR
Observations show that termite architectures can harness periodic solar heating to drive ventilation inside them in very different environments, functioning as an external lung for the colony, with clear implications for human engineering. Expand
Investigation of flow through and around the Macrotermes michaelseni termite mound skin
Macrotermitinae mounds could hold the key for designing a naturally ventilated human habitation using the sustainable Solar and Wind energies. Few attempts were made to mimic these structures intoExpand
Extended Physiology of an Insect-Built Structure
TLDR
The savannas of southern Africa are dotted with the spectacular mounds of the fungusgrowing termites of the genus Macrotermes, but how this coupling works is the focus of the research, which is underway in the southern African country of Namibia. Expand
‘Magnetic’ termite mounds: is their unique shape an adaptation to facilitate gas exchange and improve food storage?
TLDR
It is proposed that one advantage of the wedge shape is the efficient use of building effort to achieve good passive ventilation for the food storage areas in termite mounds of monsoonal northern Australia. Expand

Macrotermes michaelseni termites are found in savannah habitats throughout sub-Saharan Africa. Macrotermes michael seni differ from other species of termites in that they construct ch imney-shapedExpand
TERMITES AS MEDIATORS OF THE WATER ECONOMY OF ARID SAVANNA ECOSYSTEMS
Large termite mounds, constructed by colonies of various species of macrotermitine termites (Isoptera, Termitidae, Macrotermitinae), are dominant features of the arid and semiarid savannas ofExpand
Differential construction response to humidity by related species of mound-building termites
TLDR
It is shown that the two species demonstrate distinctive building activity in a laboratory-controlled environment consisting of still air with low ambient humidity, and this result suggests a differential behavioural threshold or sensitivity to airborne moisture that may relate to the distinct macro-scale structures observed in the African bushland.

The Structure of Mature Mounds of the Termite macrotermes Michaelseni in Kenya
TLDR
The termite Macrotermes michaelseni (Sjöstedt) builds conical earth mounds with no external openings and a closed system of inter-connected passages in the mound facilitates loss of metabolic heat to the atmosphere. Expand
Ventilation of termite mounds: new results require a new model
TLDR
The data do not support Luscher's proposed mechanism for cathedral-shaped termite mounds to exchange respiratory gases, because the CO2 concentrations in the air channels of savanna mounds at night and forest mounds in general were higher than during the day in the savanna. Expand
Air Flow, Evaporation and Mineral Accumulation in Mounds of Macrotermes subhyalinus (Rambur)
TLDR
Measurements and experiments on air flow through mounds of Macrotermes subhyalinus (Rambur) (formerly known as M. bellicosus), were done on the Serengeti Plains, Tanzania, during the months of September and October 1969, and the effect of this air flow on the thermal, mineral and water budgets of the mounds is assessed.

Production of metabolic gases by nests of the termite Macrotermes jeanneli in Kenya
Nests of a fungus-growing termite Macrotermes jeanneli discharge all their metabolic gases through a single outlet to the atmosphere. This made it possible to measure the production of metabolicExpand
Ventilation and thermal constancy of a colony of a southern African termite (Odontotermes transvaalensis: Macrotermitinae)
TLDR
It seems that ventilation of the O. transvaalensis colony does not play a significant role in the regulation of colony temperature, and other mechanisms, such as free convection within the colony, or forced ventilation by external winds, may play a minor and secondary role in translocating air inside the colony.

TLDR
Mound shape in Uganda was not correlated with the sandiness of the soil, and both Macrotermes subhyalinus and M. bellicosus were present but it was usual for one to be dominant. Expand
Social control of air ventilation in colonies of honey bees, Apis mellifera
TLDR
Fanning behaviour inside the nest of honey bees is an effective mechanism of ventilation and bees show negative phototaxis, and the colonial respiratory activity decreases at night following a pronounced day-night cycle. Expand
Architecture and morphogenesis in the mound of Macrotermes michaelseni (Sjöstedt) (Isoptera: Termitidae, Macrotermitinae) in northern Namibia
The mounds of Macrotermes michaelseni (Sjostedt) in northern Namibia have a characteristic architecture, being divided into three structurally distinct components: a central cone-shaped mound, toppedExpand
Behavioral Regulatory Mechanisms in the Social Homeostasis of Termites (Isoptera)
TLDR
An hypothesis for the significance of the behavioral phenomenon of head-banging in termites is put forward: it is considered to be connected with the maintenance of accelerated activity in a colony after “General Alarm”. Expand
