Sage-Grouse to Chicken chromosome annotation
Chromsome annotation of the Sage-Grouse using the Chicken genome. Used 1x reference-guided assembly and blast, and assumed high synteny between species.
Sage-Grouse 2x reference-guided genome
2x consensus Sage-Grouse genome from reference-guided assembly using the Chicken genome as reference. Assembly statistics report is included.
Sage-Grouse 5x reference-guided genome
5x consensus Sage-Grouse genome from reference-guided assembly using the Chicken genome as reference. Assembly statistics report is included.
Data from: Shifts and disruptions in resource-use trait syndromes during the evolution of herbaceous crops
Trait-based ecology predicts that evolution in high-resource agricultural environments should select for suites of traits that enable fast resource acquisition and rapid canopy closure. However, crop breeding targets specific agronomic attributes rather than broad trait syndromes. Breeding for speci
Data from: Accuracy of genomic selection models in a large population of open-pollinated families in white spruce
Genomic selection (GS) is of interest in breeding because of its potential for predicting the genetic value of individuals and increasing genetic gains per unit of time. To date, very few studies have reported empirical results of GS potential in the context of large population sizes and long breedi
Data from: Context-dependent reproductive isolation mediated by floral scent and color
Reproductive isolation due to pollinator behavior is considered a key mode of speciation in flowering plants. Although floral scent is thought to mediate pollinator behavior, little is known about its effects on pollinator attraction and floral visitation in the wild. We used field experiments with
Queen longevity, queen adoption, and posthumous indirect fitness in the facultatively polygynous ant <i>Myrmica tahoensis</i>
Evolution of floral traits in a hermaphroditic plant: field measurements of heritabilities and genetic correlations
Genetic variances, heritabilities, and genetic correlations of floral traits were measured in the monocarpic perennial Ipomopsis aggregata (Polemoniaceae). A paternal half-sib design was employed to generate seeds in each of four years, and seeds were planted back in the field near the parental site
Selection on flower color in an <i>Ipomopsis</i> hybrid zone
Costs and benefits of sociality in yellow-bellied marmots (<i>Marmota flaviventris</i>): do noncolonial females have lower fitness?
A new horizon for biological field stations and marine laboratories
Evolution of alternative life histories in the tiger salamander, <i>Ambystoma tigrinum nebulosum</i>
Evolution of alternative life histories in tiger salamanders (<i>Ambystoma tigrinum nebulosum</i>): a study of the cannibal morph
Genetic variation in <i>Penstemon strictus</i>: effects of island habitats
Evolution of Facultative Paedomorphosis in Salamanders
In some salamander species the retention of larval characteristics in sexually mature adults (paedomorphosis) is an alternative to metamorphosis. In many species paedomorphosis is facultative, thus offering a unique opportunity to test predictions on the evolution of life history variation. Here I e
Allozymes in evolutionary genetics: self-imposed burden or extraordinary tool?
Crossing distance effects in Delphinium nelsonii: outbreeding and inbreeding depression in progeny fitness
Inbreeding depression and maternal effects on <i>Aquilegia caerulea</i>, a partially selfing plant
Pollen discounting in Erythronium grandiflorum: mass-action estimates from pollen transfer dynamics
Pollen discounting, a reduction in success as an outcross pollen parent as a result of selfing, can reduce or eliminate the reproductive advantage commonly attributed to selfing. Previous estimates of pollen discounting have been based on segregation analysis of progeny from open-pollinated plants.
