Assessing model adequacy for Bayesian Skyline plots using posterior predictive simulation.

Autor: Emanuel M Fonseca, Drew J Duckett, Filipe G Almeida, Megan L Smith, Maria Tereza C Thomé, Bryan C Carstens

Publikováno v: PLoS ONE, Vol 17, Iss 7, p e0269438 (2022)

Bayesian skyline plots (BSPs) are a useful tool for making inferences about demographic history. For example, researchers typically apply BSPs to test hypotheses regarding how climate changes have influenced intraspecific genetic diversity over time.

The role of multiple Pleistocene refugia in promoting diversification in the Pacific Northwest

Autor: Megan L. Smith, Jessica Wallace, David C. Tank, Jack Sullivan, Bryan C. Carstens

Publikováno v: Molecular Ecology. 31:4402-4416

Pleistocene glacial cycles drastically changed the distributions of taxa endemic to temperate rainforests in the Pacific Northwest, with many experiencing reduced habitat suitability during glacial periods. In this study, we investigate whether glaci

Autor: Hannah M. Layman, Michael J. Mann, Megan L. Smith, Steven M. Kogan, Alfgeir L. Kristjansson

Publikováno v: J Sch Health

BACKGROUND: Young people who experience higher levels of social support from their schools and families have been shown to be less likely to develop symptoms of negative mental health outcomes such as depression and anxiety.(1-4) This raises question

Phylogenetic inference using Generative Adversarial Networks

Autor: Megan L. Smith, Matthew W. Hahn

MotivationThe application of machine learning approaches in phylogenetics has been impeded by the vast model space associated with inference. Supervised machine learning approaches require data from across this space to train models. Because of this,

The role of climatic and geological events in generating diversity in Ethiopian grass frogs (genus Ptychadena)

Autor: Megan L. Smith, Brice P. Noonan, Timothy J. Colston

Publikováno v: Royal Society Open Science, Vol 4, Iss 8 (2017)

Ethiopia is a world biodiversity hotspot and harbours levels of biotic endemism unmatched in the Horn of Africa, largely due to topographic—and thus habitat—complexity, which results from a very active geological and climatic history. Among Ethio
