Relationships between phyllosphere bacterial communities and plant functional traits in a neotropical forest

SW Kembel, TK O'Connor, HK Arnold… - Proceedings of the …, 2014 - National Acad Sciences
The phyllosphere—the aerial surfaces of plants, including leaves—is a ubiquitous global
habitat that harbors diverse bacterial communities. Phyllosphere bacterial communities have …

Indoor airborne bacterial communities are influenced by ventilation, occupancy, and outdoor air source

…, M Moriyama, D Northcutt, TK O'Connor… - Indoor …, 2014 - Wiley Online Library
Architects and engineers are beginning to consider a new dimension of indoor air: the structure
and composition of airborne microbial communities. A first step in this emerging field is to …

[HTML][HTML] Architectural design drives the biogeography of indoor bacterial communities

SW Kembel, JF Meadow, TK O'Connor, G Mhuireach… - PloS one, 2014 - journals.plos.org
Background Architectural design has the potential to influence the microbiology of the built
environment, with implications for human health and well-being, but the impact of design on …

Multigene phylogeny reveals eusociality evolved twice in vespid wasps

HM Hines, JH Hunt, TK O'Connor… - Proceedings of the …, 2007 - National Acad Sciences
Eusocial wasps of the family Vespidae are thought to have derived their social behavior from
a common ancestor that had a rudimentary caste-containing social system. In support of …

[HTML][HTML] Bacterial communities on classroom surfaces vary with human contact

…, AE Altrichter, SW Kembel, M Moriyama, TK O'Connor… - Microbiome, 2014 - Springer
Background Humans can spend the majority of their time indoors, but little is known about
the interactions between the human and built-environment microbiomes or the forces that …

[HTML][HTML] Significant changes in the skin microbiome mediated by the sport of roller derby

JF Meadow, AC Bateman, KM Herkert, TK O'Connor… - PeerJ, 2013 - peerj.com
Diverse bacterial communities live on and in human skin. These complex communities vary
by skin location on the body, over time, between individuals, and between geographic …

Evolution of herbivory remodels a Drosophila genome

…, SC Groen, DH Hembry, CJ Ochoa, TK O'Connor… - Biorxiv, 2019 - biorxiv.org
One-quarter of extant Eukaryotic species are herbivorous insects, yet the genomic basis of
this extraordinary adaptive radiation is unclear. Recently-derived herbivorous species hold …

Polyploidy in creosote bush (Larrea tridentata) shapes the biogeography of specialist herbivores

TK O'Connor, RG Laport… - Journal of …, 2019 - Wiley Online Library
Aim Whole‐genome duplication (polyploidy) can influence the biogeography and ecology of
plants that differ in ploidy level (cytotype). Here, we address how two consequences of plant …

[HTML][HTML] The biogeography of putative microbial antibiotic production

H Morlon, TK O'Connor, JA Bryant, LK Charkoudian… - PloS one, 2015 - journals.plos.org
