Geographic variation in reproductive assurance of Clarkia pulchella.
Bontrager M, Muir CD, Angert AL. Bontrager M, et al. Oecologia. 2019 May;190(1):59-67. doi: 10.1007/s00442-019-04390-4. Epub 2019 Apr 6. Oecologia. 2019. PMID: 30953167
We manipulated pollinator access to plants in eight sites spanning the geographic range of Clarkia pulchella to investigate geographic and climatic drivers of fruit production and seed set in the absence of pollinators (reproductive assurance). ...In the absence of …

Effects of range-wide variation in climate and isolation on floral traits and reproductive output of Clarkia pulchella.
Bontrager M, Angert AL. Bontrager M, et al. Am J Bot. 2016 Jan;103(1):10-21. doi: 10.3732/ajb.1500091. Epub 2015 Sep 11. Am J Bot. 2016. PMID: 26362193 Free article.
Here, we examined how spatiotemporal variation in climate affects reproductive output of a mixed-mating annual, Clarkia pulchella. We also tested the effects of population isolation and climate on mating-system-related floral traits across the range. METHODS: We mea …

INCREASED PROBABILITY OF EXTINCTION DUE TO DECREASED GENETIC EFFECTIVE POPULATION SIZE: EXPERIMENTAL POPULATIONS OF CLARKIA PULCHELLA.
Newman D, Pilson D. Newman D, et al. Evolution. 1997 Apr;51(2):354-362. doi: 10.1111/j.1558-5646.1997.tb02422.x. Evolution. 1997. PMID: 28565367
We established replicated experimental populations of the annual plant Clarkia pulchella to evaluate the existence of a causal relationship between loss of genetic variation and population survival probability. ...

Gene flow improves fitness at a range edge under climate change.
Bontrager M, Angert AL. Bontrager M, et al. Evol Lett. 2018 Nov 30;3(1):55-68. doi: 10.1002/evl3.91. eCollection 2019 Feb. Evol Lett. 2018. PMID: 30788142 Free PMC article.
We tested these competing predictions in the annual wildflower Clarkia pulchella using greenhouse crosses to simulate gene flow from sources across the geographic range into two populations at the northern range margin. ...

Eight generations of native seed cultivation reduces plant fitness relative to the wild progenitor population.
Pizza R, Espeland E, Etterson J. Pizza R, et al. Evol Appl. 2021 May 4;14(7):1816-1829. doi: 10.1111/eva.13243. eCollection 2021 Jul. Evol Appl. 2021. PMID: 34295366 Free PMC article.
To test this, we grew the eighth generation of farm-propagated Clarkia pulchella Pursh (Onagraceae) alongside seeds from two of the three original wild source populations that established the native seed farm. ...

Indirect competition for pollinators is weak compared to direct resource competition: pollination and performance in the face of an invader.
Palladini JD, Maron JL. Palladini JD, et al. Oecologia. 2013 Aug;172(4):1061-9. doi: 10.1007/s00442-012-2556-9. Epub 2012 Dec 15. Oecologia. 2013. PMID: 23242427
We quantified the direct effects of resource competition by the invasive perennial forb, Euphorbia esula (Euphorbiaceae), on the recruitment, subsequent performance, and ultimate adult abundance of the native annual, Clarkia pulchella (Onagraceae). We contrast these …
