His collaborator, Australian theoretical physicist Robert May, later showed that communities of species that were more diverse and more complex were actually less able to maintain an exact stable numerical balance among species.
The new molecules, drilled from three-billion-year-old mudstones that were laid down in a lake environment, are more diverse and more complex.
Following the Oldowan, stone tools became more diverse and more complex or difficult to manufacture, and the tradition was in full swing by about 1.5 million years ago.
"The county's only getting bigger and more diverse and more complex". The Board of Supervisors took a big step toward the new system Tuesday by approving a $15-million 15-millionith a Palo Alto contractnt to design the newithstem.
NRs then acquired the ability to homo- or heterodimerize and to interact with specific ligands, allowing the regulation of more diverse and more complex physiological processes.
The gain of a dimorphic trait was associated with an increased rate of evolution and the appearance of many new species with diverse and more complex mouthparts.
As such, the role of methylation in humans is likely more diverse and more complex than current hypotheses derived from 450K analyses attest, and the approach of our method can serve as a valuable tool in elucidating this complexity.
However, addressing quality of evidence in the complex and variable terrain of public health, with its diverse and more complex questions (when, how, how cost-effective, and how sustainable) and with its heterogeneous forms of evidence, is far less cut-and-dried.
While orchards near Lake Ontario often have expansive swaths of apple trees, elsewhere in New York, orchards are often rimmed by woody areas or nearby fields planted with diverse crops, offering more complex environments for bees.
