Data from: A computational model of flow between the microscale respiratory structures of fish gills

James A. Strother
The gills of most teleost fishes are covered by plate-like structures, the secondary lamellae, that provide the bulk of the respiratory surface area. Water passing over the secondary lamellae exchanges gases with blood passing through the secondary lamellae, forming a system that has served as a classic model of counter-current exchange. In this study, a computational model of flow around the secondary lamellae is used to examine the hydrodynamic consequences of changes to the lamellar...

Data from: The role of inbreeding depression and mating system in the evolution of heterostyly

Jennifer J. Weber, Stephen G. Weller, Ann K. Sakai, Olga V. Tsyusko, Travis C. Glenn, Cesar A. Dominguez, Francisco E. Molina-Freaner, Juan Fornoni, Mike Tran, Nhu Nguyen, Karen Nguyen, Lien-Khuong Tran, Greg Joice & Ellen Harding
We investigated the role of morph-based differences in the expression of inbreeding depression in loss of the mid-styled morph from populations of tristylous Oxalis alpina as proposed by theoretical analyses. The extent of self-compatibility of reproductive morphs, the degree of self-fertilization, and the magnitude of inbreeding depression were investigated in three populations of O. alpina differing in their tristylous incompatibility relationships. All three populations exhibited significant inbreeding depression. In two populations with highly modified tristylous...

Data from: The genetic architecture of methotrexate toxicity is similar in Drosophila melanogaster and humans

Galina Kislukhin, Elizabeth G. King, Kelli N. Walters, Stuart J. Macdonald & Anthony D. Long
The severity of the toxic side effects of chemotherapy varies among patients, and much of this variation is likely genetically based. Here, we use the model system Drosophila melanogaster to genetically dissect the toxicity of methotrexate (MTX), a drug used primarily to treat childhood acute lymphoblastic leukemia and rheumatoid arthritis. We use the Drosophila Synthetic Population Resource, a panel of recombinant inbred lines derived from a multiparent advanced intercross, and quantify MTX toxicity as a...

Data from: Fine-scale analysis of parasite resistance genes in the red flour beetle, Tribolium castaneum

Daibin Zhong, Aditi Pai, Mei-Hui Wang, Naomi Keech & Guiyun Yan
Parasite infection impacts population dynamics through effects on fitness and fecundity of the individual host. In addition to the known roles of environmental factors, host susceptibility to parasites has a genetic basis that has not been well characterized. We previously mapped quantitative trait loci (QTL) for susceptibility to rat tapeworm (Hymenolepis diminuta) infection in Tribolium castaneum using dominant AFLP markers, but the resistance genes were not identified. In the current study, we refined the QTL...

Data from: Segregation of male sterility alleles across a species boundary

Stephen G. Weller, Ann K. Sakai, Theresa M. Culley, Loan Duong & Rachel E. Danielson
Hybrid zones may serve as bridges permitting gene flow between species, including alleles influencing the evolution of breeding systems. Using greenhouse crosses, we assessed the likelihood that a hybrid zone could serve as a conduit for transfer of nuclear male-sterility alleles between a gynodioecious species and a hermaphroditic species with very rare females in some populations. Segregation patterns in progeny of crosses between rare females of hermaphroditic Schiedea menziesii and hermaphroditic plants of gynodioecious Schiedea...
