We study the tunnelling network dynamics of two morphologically and ecologically very similar native termite species from the Brazilian Cerrado, Cornitermes cumulans and Procornitermes araujoi, both when they are digging alone or when their tunnel networks can meet. Their network topologies have the same geometrical properties with only slight differences in digging speed and branching rates. Petri dish laboratory assays show that the two species have a strong potential for interference… 

Network-based model of the growth of termite nests.

TLDR
The model based on the empirical analysis of the real nest networks combined with pruning, edge removal and a memory effect successfully predicts emergent nest properties and indicates that Termitinae networks favor fast internal transportation over efficient defense strategies against ant predators.

Differential undertaking response of a lower termite to congeneric and conspecific corpses

TLDR
The findings suggest elicitation of undertaking behaviour depends on the origin of corpses which is associated with different types of risk, and that R. flavipes exhibited distinctively different behaviours toward dead termites from various origins.

A Comprehensive Understanding of Corpse Management in Termites

TLDR
This work reviews mechanisms of death recognition, convergent and divergent behavioral responses toward dead individuals, and undertaking task allocation from the perspective of division of labor in hymenoptera and Isoptera.

Ecology of Termites

TLDR
The ecological role of termites is examined and explored and it is shown that these tiny insects are a center of attraction because they damage the human economy as wood pests.

Coordination of construction behavior in the termite Procornitermes araujoi: structure is a stronger stimulus than volatile marking

TLDR
Beyond shedding light on the behavioral mechanisms of termite shelter construction, these results also stress the necessity of direct experimental approaches in order to identify and properly weight different coordination mechanisms underlying morphogenesis in biological systems.

Wood-Feeding Termites

TLDR
The evolution of modern termites can be reconstructed as a stepwise process to secure the transfer of increasingly specialised intestinal symbionts from parent to offspring, resulting in the extant eusociality of all termites.

Coordination of construction behavior in the termite Procornitermes araujoi: structure is a stronger stimulus than volatile marking

TLDR
Beyond shedding light on the behavioral mechanisms of termite shelter construction, these results also stress the necessity of direct experimental approaches in order to identify and properly weight different coordination mechanisms underlying morphogenesis in biological systems.

Interference competition in desert subterranean termites

TLDR
The pattern of co‐occurrence of these two species is consistent with the hypothesis that interspecific interference competition affects their spatial and temporal distribution.

Nest excavation in ants: group size effects on the size and structure of tunneling networks

TLDR
The digging dynamics and topology of tunneling networks excavated by groups of workers ranging from 50 to 200 individuals over 3 days were analyzed and it was found that all the networks belonged to the same topological family and exhibited several striking invariants such as the distribution of vertex degree that follows a power law.

Tunnel Volume Regulation and Group Size of Subterranean Termites (Isoptera: Rhinotermitidae)

TLDR
The shape of the growth curves for tunnel volumes indicated the presence of a double feedback system for termite tunneling activity, and it is suggested that the positive relationship between nest and population size previously reported for numerous termites species is the result of the self-organized nest-building activity.

Interspecific Competition and Territory Defense Mechanisms of Coptotermes formosanus and Coptotermes gestroi (Isoptera: Rhinotermitidae)

TLDR
Results of two bioassays in the current study showed that C. gestroi was more aggressive than C. formosanus, and sealed individual tunnels in response to encounters with other species acts to prevent further agonism and mortality, and on a broad scale the aggregate of such blocked tunnels may come to define the borders between adjacent colonies.

The system of underground passages in Macrotermes subhyalinus and comparison of laboratory bioassays to field evidence of intraspecific encounters in M. subhyalinus and M. bellicosus (Isoptera, Termitidae)

TLDR
The system of underground passages and storage pits used in foraging have been excavated in two nests of the termite Macrotermes subhyalinus in West Africa (Ivory Coast) and results of laboratory bioassays were connected to unmanipulated field evidence of termite agonism.

Multi-scale pattern analysis of a mound-building termite species

TLDR
Analysis of mound distribution patterns of a fungus-growing termite species, Macrotermes michaelseni, an important ecosystem engineer in the savannas of Namibia, indicates that intraspecific competition for foraging areas controls mound distribution pattern and colony size.

Dead Reckoning in Tunnel Propagation of the Formosan Subterranean Termite (Isoptera:Rhinotermitidae)

TLDR
Exavation in termites was not coordinated solely by stigmergy, because tunnelers did not rely on local cues alone while digging, but the removal of soil from sites at the tunnel tip was governed by their ability to generate a GAV through dead reckoning.
