Journal ArticleDOI
Early-life disruption of amphibian microbiota decreases later-life resistance to parasites
Sarah A. Knutie,Sarah A. Knutie,Christina L. Wilkinson,Kevin D. Kohl,Kevin D. Kohl,Jason R. Rohr +5 more
TL;DR: Manipulating the microbiota of tadpoles leads to increased susceptibility to parasitic infection in adult frogs, in the absence of substantial changes in the adults’ microbiota, which supports the idea that preventing early-life disruption of host-associated microbiota might confer protection against diseases later in life.
Journal ArticleDOI
Epigenetics and the Evolution of Darwin's Finches
Michael K. Skinner,Carlos Gurerrero-Bosagna,M. Muksitul Haque,Eric E. Nilsson,Jennifer A. H. Koop,Sarah A. Knutie,Dale H. Clayton +6 more
TL;DR: The number, chromosomal locations, regional clustering, and lack of overlap of epimutations and genetic mutations suggest that epigenetic changes are distinct and that they correlate with the evolutionary history of Darwin’s finches.
Journal ArticleDOI
Epigenetic variation between urban and rural populations of Darwin’s finches
Sabrina M. McNew,Daniel Beck,Ingrid Sadler-Riggleman,Sarah A. Knutie,Jennifer A. H. Koop,Dale H. Clayton,Michael K. Skinner +6 more
TL;DR: This study explored variation between populations of Darwin’s finches, which comprise one of the best-studied examples of adaptive radiation, and found dramatic epigenetic differences between the urban and rural populations of both species.
Journal ArticleDOI
Galápagos mockingbirds tolerate introduced parasites that affect Darwin's finches
Sarah A. Knutie,Jeb P. Owen,Sabrina M. McNew,Andrew W. Bartlow,Elena Arriero,Jordan M. Herman,Emily DiBlasi,Michael D. Thompson,Jennifer A. H. Koop,Dale H. Clayton +9 more
TL;DR: The results of this study suggest that finches are negatively affected by P. downsi because they do not have such behavioral mechanisms for energy compensation, and mockingbirds are capable of compensation, making them tolerant hosts, and a possible indirect threat to Darwin's finches.
Journal ArticleDOI
Darwin's finches combat introduced nest parasites with fumigated cotton.
TL;DR: It is shown that Darwin's finches can be encouraged to 'self-fumigate' nests with cotton fibers that have been treated with permethrin, and nests containing at least one gram of cotton were virtually parasite-free.
