Optimal reproduction strategies in two species of mound-building termites.
We formulate a mathematical model for food collection and production of workers and nymphs in 2 species of mound building termites. We maximise the number of nymphs (reproductives) produced by each colony over its lifetime with respect to the proportion of eggs that hatch as nymphs as opposed to workers. The results predict that food storage has a very important influence on the pattern of nymp...
متن کاملExcavation and aggregation as organizing factors in de novo construction by mound-building termites.
Termites construct complex mounds that are orders of magnitude larger than any individual and fulfil a variety of functional roles. Yet the processes through which these mounds are built, and by which the insects organize their efforts, remain poorly understood. The traditional understanding focuses on stigmergy, a form of indirect communication in which actions that change the environment prov...
متن کاملThe impact of mound-building termites on surface soil properties in a secondary forest of Central Amazonia
Termites are important components of biologically mediated feedback to land-use change in the tropics. In Central Amazonia, termite mounds are prevalent in post-clearing landscapes and appear to constrain re-colonization of the landscape by vegetation. To determine the most important constraints imposed by termite mounds on plant establishment, we investigated chemical, physical, and hydraulic ...
متن کاملPedosedimentary Evolution and Site Formation Processes in Mirak Mound 8, South of Semnan
Mirak is one of the open-air Paleolithic sites in the Iranian Central Plateau and the only Iranian archaeological open-air site which has been excavated extensively. The site is comprised of 8 mounds, located in a dry floodplain some kilometers south of Semnan in the northern fringes of the Iranian Central Desert, aka. Dash-I Kavir. Mirak mound no. 8 was selected for the excavation. The mound i...
متن کاملBacteria from the gut of Australian termites.
The major gut bacteria of the worker caste of nine species of Australian termites, belonging to four families, were isolated and identified to generic level. All species were either facultative anaerobes or strict aerobes. A correlation appears to exist between the major gut bacterium and the family to which the termite belongs. The major bacterium from the two lowest termites, Mastotermes darw...
