Sentences with phrase «eusociality in»

Phylogenomics Controlling for Base Compositional Bias Reveals a Single Origin of Eusociality in Corbiculate Bees.

As we show here, it is certainly feasible that extensive Hymenoptera - specific immune components exist, and until similar studies are performed across diverse Hymenoptera species it will be difficult to fully disentangle the role of eusociality in the evolution of Hymenopteran immunity.

«These findings suggest that the evolution of eusociality in Synalpheus shrimp has left a signal in the allometry of female reproduction and defense.»

Although being phylogenetically and ecologically distinct from insects, it turns out that the evolution of eusociality in snapping shrimps follows the so - called «subsocial route» first proposed for insects nearly 50 years ago.

Not exact matches

Writing in the 17 January issue of Science, the researchers say the new insights «could contribute greatly to our understanding of the evolution of eusociality» in insects.

(Among vertebrates, eusociality is found in just two species of African mole rats.)

Eusociality occurs in a range of arthropods, from some shrimp, beetles, and aphids, to various wasps, though the phenomenon is nowhere more pronounced than in honey bees, ants, and termites.

A number of spectacular pieces of amber recently recovered from Myanmar gave Barden, Grimaldi, and their colleagues a clear answer: Eusociality was going strong in both groups during the Cretaceous.

People who are open - minded are beginning to realise that the results of our paper are beautiful: simple mathematical models based on standard natural selection are sufficient to explain the evolution of eusociality or other phenomena in social evolution.

Snapping shrimps in the genus Synalpheus are the only known marine genus that has evolved eusociality.

«Tradeoffs between weaponry and fecundity in snapping shrimp queens vary with eusociality: Weakly eusocial queens must trade off their investment in maintaining their fighting claws or producing eggs.»

«First, there is no single road map to eusociality — the complex, cooperative social system in which animals behave more like superorganisms than individuals fending for themselves,» said Gene Robinson, a lead on the study who is a professor of entomology and director of the Carl R. Woese Institute for Genomic Biology at the University of Illinois.

In the 1980s, Wilson himself was a strong proponent of this theory to explain the origins of eusociality — the type of very complex society seen in bees, ants, and termiteIn the 1980s, Wilson himself was a strong proponent of this theory to explain the origins of eusociality — the type of very complex society seen in bees, ants, and termitein bees, ants, and termites.

But Jamie Hunt, a zoologist at North Carolina State University in Raleigh, says the work has «serious shortcomings,» showing only that monogamy correlates with eusociality without necessarily causing it.

When Hughes's group examined the distribution of monogamous versus polygamous species among the eight branches of the family tree in which eusociality had independently evolved, the researchers concluded that each branch had started with a monogamous species.

Within Hymenoptera, considerable interest has focused on the role that eusociality plays in shaping the evolution of the immune system [7], [8], [36], [38], [73], with at least some suggestion that social species may have a reduced complement of immune - related genes.

The evolution of eusociality has been associated with a 100-fold increase in insect lifespan.
