A method for testing the assumption of phylogenetic independence in comparative data
- E. Abouheif
- Biology
- 1999
This work presents the application of a statistical diagnostic called the ‘test for serial independence’, which can be applied to almost all currently employed PCMs, including Felsenstein’s (1985) independent contrasts.
The evolution of transcriptional regulation in eukaryotes.
The evolutionary dynamics of promoter, or cis-regulatory, sequences and the evolutionary mechanisms that shape them are reviewed.
A Comparative Analysis of Allometry for Sexual Size Dimorphism: Assessing Rensch's Rule
- E. Abouheif, D. Fairbairn
- Environmental Science, BiologyAmerican Naturalist
- 1 March 1997
Rensch's rule is shown to be associated with male-biased SSD, which is consistent with the hypothesis that sexual selection acting on male size drives the evolution of this pattern of allometry.
The role of developmental plasticity in evolutionary innovation
- A. Moczek, S. Sultan, D. Pfennig
- BiologyProceedings of the Royal Society B: Biological…
- 22 September 2011
Three distinct ways by which developmental plasticity can promote evolutionary innovation are examined, showing how the process of genetic accommodation provides a feasible and possibly common avenue by which environmentally induced phenotypes can become subject to heritable modification.
The Genome Sequence of the Leaf-Cutter Ant Atta cephalotes Reveals Insights into Its Obligate Symbiotic Lifestyle
- G. Suen, C. Teiling, C. Currie
- BiologyPLoS Genetics
- 1 February 2011
Following recent reports of genome sequences from other insects that engage in symbioses with beneficial microbes, the A. cephalotes genome provides new insights into the symbiotic lifestyle of this ant and advances the understanding of host–microbe symbioss.
Draft genome of the globally widespread and invasive Argentine ant (Linepithema humile)
- Chris D. Smith, A. Zimin, N. Tsutsui
- BiologyProceedings of the National Academy of Sciences
- 31 January 2011
The draft genome sequence of a particularly widespread and well-studied species, the invasive Argentine ant, is reported, which was accomplished using a combination of 454 and Illumina sequencing and community-based funding rather than federal grant support.
Comparative methods for the analysis of gene-expression evolution: an example using yeast functional genomic data.
- Todd H. Oakley, Z. Gu, E. Abouheif, N. Patel, Wen-Hsiung Li
- BiologyMolecular biology and evolution
- 2005
It is found that expression of duplicated genes has evolved according to a nonphylogenetic model, where closely related genes are no more likely than more distantly related genes to share common expression patterns.
Evolution of the Gene Network Underlying Wing Polyphenism in Ants
- E. Abouheif, G. Wray
- BiologyScience
- 12 July 2002
The expression of several genes within the network within the wing primordia of reproductive (winged) and sterile (wingless) ant castes is conserved in the winged castes of four ant species, whereas points of interruption within thenetwork in theWingless castes are evolutionarily labile.
Draft genome of the red harvester ant Pogonomyrmex barbatus
- Chris C. R. Smith, Christopher D. Smith, J. Gadau
- BiologyProceedings of the National Academy of Sciences
- 31 January 2011
Gene networks involved in generating key differences between the queen and worker castes show signatures of increased methylation and suggest that ants and bees may have independently co-opted the same gene regulatory mechanisms for reproductive division of labor.
Ancestral Developmental Potential Facilitates Parallel Evolution in Ants
- Rajendhran Rajakumar, Diego San Mauro, E. Abouheif
- BiologyScience
- 6 January 2012
An ancestral developmental potential to produce a “supersoldier” subcaste that has been actualized at least two times independently in the hyperdiverse ant genus Pheidole is uncovered, which may facilitate the adaptive and parallel evolution of phenotypes.
