Termites Can Monitor The Communication That Takes Place Between Termites Of Competing Species

While apex predators do exist, animals that exercise total dominance over a particular region’s resources are rare in nature. Unlike the very few apex predators that exist, most animal species are forced to indulge in frequent battles over resources, and these violent battles can be costly for species. It is for this reason that most animals dwell within particular locales that are free of other hostile animals. It is when animals forage away from their nests or shelters that they become faced with threats that could erupt into full blown battles. Considering the relatively small size of termites and the isolated and well fortressed nesting sites that they inhabit, the daily life of a termite clearly entails constant threats from other competing animals, especially ants. In addition to ants, termites face significant competition from other termite species. This is because most regions of the world, especially tropical regions, are home to a variety of different termite species, all of which are competing for the very same resources. Despite the naturally belligerent relationship that exists between most termites of different species, it is surprising to learn that multiple species often inhabit the same nesting site. As you can imagine, interspecies battles between termites occur frequently when they inhabit the same nest. However, by eavesdropping on their more dominant subterranean counterparts, drywood termites can escape from violent encounters before they occur.

It may seem odd that competing termite species may dwell within the same nest, but sometimes, having access to the resources that a nest provides outweighs the risk of falling victim to a violent encounter with an enemy species. However, researchers have long been confused by the presence of drywood termites in pieces of wood that are dominated by a far greater number of subterranean termites. Drywood termite colonies grow to contain a few hundred individual termites, but subterranean termites dwell within colonies containing millions of individual termites. Considering this, it would seem that drywood termites are at a tremendous disadvantage, but how do they continue to survive within such a hostile environment? As it turns out, the Cryptotermes secundus species of drywood termite is blessed with the ability to recognize the vibro-acoustic communication signals that take place between their nearby subterranean enemies, the Coptotermes acinaciformis species. The drywood termites of this species are attracted to their own vibration signals, but they are repelled by the vibrations produced by subterranean termites. In fact, as a cohabitated piece of wood becomes smaller as a result of constant feeding, the drywood termites become progressively more repelled by the vibration signals produced by their subterranean enemies. This makes sense considering that the chances of falling victim to a subterranean termite attack increases as the piece of infested wood becomes smaller. To put it simply, these drywood termites indulge in espionage in order to gain an advantage over their more powerful subterranean enemies.

Do you think that subterranean termites are capable of differentiating between their own vibration signals and those of other species?
