  • species
  • Here we investigated whether the dissimilarities in cuticle chemical signals in females of different castes and life stages reflect the level of social complexity across halictid bee species. (springer.com)
  • Our hypothesis was that species with a higher social behavior ergo obligate eusocial species possess a more distinct chemical profile between castes or female life stages. (springer.com)
  • We analyzed cuticular chemical profiles of foundresses, breeding females and workers of ancestrally solitary species, facultative and obligate eusocial halictid species. (springer.com)
  • Our results revealed higher chemical dissimilarity between castes in obligate than in facultative eusocial species, especially regarding macrocyclic lactones, which were the single common compound class overproduced in queens compared with workers. (springer.com)
  • Reactions
  • Illites show a clear increase in K. These factors indicate that a continuous chemical modification of these minerals takes place in the diagenetic interval studied through continuous dissolution and precipitation reactions. (springer.com)

  • gene
  • The researchers found that many genes had lost one parental version within just 40 generations of evolution and patterns of gene loss were not random. (qmul.ac.uk)
  • Five different natural populations of independent origin showed similar patterns of gene loss, meaning evolution repeated itself. (qmul.ac.uk)
  • This includes work on how processes such as concerted evolution and gene duplication can underpin phenotypic stability and novelty. (qmul.ac.uk)
  • complexes
  • 25 Another type of intriguing 2D material is coordination nanosheets (CONASHs), 26,27 which consist of metal complexes and can exhibit various unique physical and chemical features. (rsc.org)
  • overpotential
  • Furthermore, comparison of cyclic voltammograms of CoMC6*a and CoMP11-Ac indicates that the trifluoroethanol-induced folding of CoMC6*a lowers the overpotential for catalytic H 2 evolution by up to 100 mV. (rsc.org)
  • Buggs
  • We are applying the latest sequencing technologies to tackle ash dieback ( Buggs ), resolve ecological networks ( Clare ), understand the evolution of invertebrate nervous systems ( Elphick and Stollewerk ) and unlock the genetic basis of ageing in long-lived naked mole rats ( Faulkes ).

  • nervous
  • The paper came out following a Royal Society discussion meeting on the 'Origin and evolution of the nervous system' in March 2015. (qmul.ac.uk)
  • Behaviour
  • The data clearly show that in order to understand the evolution of shape and behaviour, we have to go beyond detecting genes and sequence variations in genomes. (qmul.ac.uk)
  • We are broadly interested in identifying and characterising genomic changes involved in social evolution and social behaviour. (qmul.ac.uk)
