Stable isotope ratios indicate that body condition in migrating passerines is influenced by winter habitat [PDF]

open access: yes, 2004
Although predicted some time ago, there has been little success in demonstrating that the overall fitness of migratory birds depends on the combined influences of their experiences over all seasons.

Genetic signature of natural selection in first Americans [PDF]

open access: yesProceedings of the National Academy of Sciences, 2017
Significance There is much interest in understanding the role of natural selection in shaping physiological adaptations to climate, diet, and diseases in humans. We investigated this issue by analyzing genomic data from Native American populations inhabiting different ecological regions and ancient Native Americans.

The Genome-wide Signature of Short-term Temporal Selection

open access: yesProceedings of the National Academy of Sciences, 2023
AbstractDespite evolutionary biology’s obsession with natural selection, few studies have evaluated multi-generational series of patterns of selection on a genome-wide scale in natural populations. Here, we report on a nine-year population-genomic survey of the microcrustaceanDaphnia pulex.The genome-sequences of > 800 isolates provide insights into

Signatures of Selection in Composite Vrindavani Cattle of India [PDF]

open access: yesFrontiers in Genetics, 2020
Vrindavani is an Indian composite cattle breed developed by crossbreeding taurine dairy breeds with native indicine cattle. The constituent breeds were selected for higher milk production and adaptation to the tropical climate. However, the selection response for production and adaptation traits in the Vrindavani genome is not ...

The Cure: Making a game of gene selection for breast cancer survival prediction [PDF]

open access: yes, 2014
Motivation: Molecular signatures for predicting breast cancer prognosis could greatly improve care through personalization of treatment. Computational analyses of genome-wide expression datasets have identified such signatures, but these signatures leave

Identifying signatures of sexual selection using genomewide selection components analysis

open access: yesEcology and Evolution, 2015
AbstractSexual selection must affect the genome for it to have an evolutionary impact, yet signatures of selection remain elusive. Here we use an individual‐based model to investigate the utility of genome‐wide selection components analysis, which compares allele frequencies of individuals at different life history stages within a single population to ...

Unravelling selection signatures in a single dog breed suggests recent selection for morphological and behavioral traits

open access: yesAdvanced Genetics, 2020
Strong selection has resulted in substantial morphological and behavioral diversity across modern dog breeds, which makes dogs interesting model animals to study the underlying genetic architecture of these traits.

Detecting signatures of balancing selection to identify targets of anti-parasite immunity.

open access: yes, 2010
Parasite antigen genes might evolve under frequency-dependent immune selection. The distinctive patterns of polymorphism that result can be detected using population genetic methods that test for signatures of balancing selection, allowing genes encoding

An evaluation of DNA-damage response and cell-cycle pathways for breast cancer classification [PDF]

open access: yes, 2014
Accurate subtyping or classification of breast cancer is important for ensuring proper treatment of patients and also for understanding the molecular mechanisms driving this disease.

A Genetic Investigation of Island Jersey Cattle, the Foundation of the Jersey Breed: Comparing Population Structure and Selection to Guernsey, Holstein, and United States Jersey Cattle

open access: yesFrontiers in Genetics, 2020
For two centuries, Jersey cattle were exported globally, adapting to varying climates and production systems, yet the founding population remained genetically isolated on the Island of Jersey. The Island of Jersey formally allowed the importation of pure
