Shape transition during nest digging in ants.
Nest building in social insects is among the collective processes that show highly conservative features such as basic modules (chambers and galleries) or homeostatic properties. Although ant nests share common characteristics, they exhibit a high structural variability, of which morphogenesis and underlying mechanisms remain largely unknown. We conducted two-dimensional nest-digging experiment...
متن کاملExcavated substrate modulates growth instability during nest building in ants.
In social insects, the nests of the same species can show a large difference in size and shape. Despite these large variations, the nests share the same substructures, some appearing during nest growth. In ants, the interplay between nest size and digging activity leads to two successive morphological transitions from circular to branched shapes (budding along the perimeter of the circular cavi...
متن کاملPath Integration Controls Nest-Plume Following in Desert Ants
The desert ant Cataglyphis fortis is equipped with sophisticated navigational skills for returning to its nest after foraging. The ant's primary means for long-distance navigation is path integration, which provides a continuous readout of the ant's approximate distance and direction from the nest. The nest is pinpointed with the aid of visual and olfactory landmarks. Similar landmark cues help...
متن کاملNest-mark orientation versus vector navigation in desert ants.
Foraging ants and bees use path-integration vectors and landmark cues for navigation. When in particular experimental paradigms the two types of information--vector-based and landmark-based information--are made to compete with each other, the insect may weight either source more heavily depending on the navigational context and the animal's motivational state. Here we studied the effects of a ...
متن کاملCopper Corrosion Inhibitors. A review
The literature dealing with the electrochemical corrosion of copper and possibility of its prevention using inhibitors is examined. Inorganic compounds are investigated as well, but organic compounds and their derivatives in much greater numbers. Researches are directed to influence of compounds structure, concentration, method of application as well as media that inhibitor is used in on inhibi...
