Queens of the primitively eusocial wasp Ropalidia marginata appear to maintain reproductive monopoly through pheromone rather than through physical aggression. Upon queen removal, one of the workers (potential queen, PQ) becomes extremely aggressive but drops her aggression immediately upon returning the queen. If the queen is not returned, the PQ gradually drops her aggression and becomes the ...
world's history presents only during occasional long periods of widespread prosperity, to Mr. Lytton's eyes her personal influence does not account either for the great events that happened in her time or for the eminence of the chief characters which surrounded her. We see in his biography, what is lacking in the earlier book, a sincere attempt to refrain from belittling his subject, but certa...
The breeding system of social organisms affects many important aspects of social life. Some species vary greatly in the number of breeders per group, but the mechanisms and selective pressures contributing to the maintenance of this polymorphism in social structure remain poorly understood. Here, we take advantage of a genetic dataset that spans 15 years to investigate the dynamics of colony qu...
Ascomycete fungi in the nests of ants inhabiting plants (= myrmecophytes) are very often cultivated by the ants in small patches and used as food source. Where these fungi come from is not known yet. Two scenarios of fungus recruitment are possible: (1) random infection through spores or hyphal fragments from the environment, or (2) transmission from mother to daughter colonies by the foundress...
We show that if a graph G satisfies certain conditions, then the connectivity of neighbourhood complex N(G) is strictly less than vertex G. As an application, we give relation between and for stiff chordal graphs, weakly triangulated graphs satisfying properties. Next, consider with v such any k-subset S neighbours v, there exists vS≠v subset vS. prove as above, N(G−{v}) (k−1)-connected implies...
The main problem of modern phytotherapy is the medicinal plants that have a sufficient raw material base and contain large number biologically active substances. Treatment diseases with synthetic drugs leads to development resistance pathogenic microflora appearance allergic reactions. Therefore, solve this problem, it necessary find new plant-based antimicrobials are safe for long-term use wid...
