Li Y, Wilson D, Grundel R, Campbell S, Knight J, Perry J, et al.
PLoS One . 2023 Nov; 18(11):e0262382. PMID: 37934780
The Karner blue butterfly (Lycaeides melissa samuelis, or Kbb), a federally endangered species under the U.S. Endangered Species Act in decline due to habitat loss, can be further threatened by...

Zarnetske P, Gurevitch J, Franklin J, Groffman P, Harrison C, Hellmann J, et al.
Proc Natl Acad Sci U S A . 2021 Apr; 118(15). PMID: 33876741
As the effects of anthropogenic climate change become more severe, several approaches for deliberate climate intervention to reduce or stabilize Earth's surface temperature have been proposed. Solar radiation modification (SRM)...

Grecequet M, DeWaard J, Hellmann J, Abel G
Sustainability . 2018 May; 9(5). PMID: 29707262
The relationship between climate change and human migration is not homogenous and depends critically on the differential vulnerability of population and places. If places and populations are not vulnerable, or...

Ryan S, Deines J, Scriber J, Pfrender M, Jones S, Emrich S, et al.
Proc Natl Acad Sci U S A . 2018 Feb; 115(10):E2284-E2291. PMID: 29463695
Climate-mediated changes in hybridization will dramatically alter the genetic diversity, adaptive capacity, and evolutionary trajectory of interbreeding species. Our ability to predict the consequences of such changes will be key...

Ryan S, Fontaine M, Scriber J, Pfrender M, ONeil S, Hellmann J
Mol Ecol . 2017 Jul; 26(18):4725-4742. PMID: 28727195
Hybrid zones are a valuable tool for studying the process of speciation and for identifying the genomic regions undergoing divergence and the ecological (extrinsic) and nonecological (intrinsic) factors involved. Here,...

McLaughlin J, Hellmann J, Boggs C, Ehrlich P
Oecologia . 2017 May; 132(4):538-548. PMID: 28547640
We compare results of field study and model analysis of two butterfly populations to evaluate the importance of alternative mechanisms causing changes in abundance. Although understanding and predicting population fluctuations...

Hellmann J, Grundel R, Hoving C, Schuurman G
Curr Opin Insect Sci . 2016 Oct; 17:92-97. PMID: 27720080
As climate change moves insect systems into uncharted territory, more knowledge about insect dynamics and the factors that drive them could enable us to better manage and conserve insect communities....

Hallfors M, Liao J, Dzurisin J, Grundel R, Hyvarinen M, Towle K, et al.
Ecol Appl . 2016 Aug; 26(4):1154-69. PMID: 27509755
Species distribution models (SDMs) have been criticized for involving assumptions that ignore or categorize many ecologically relevant factors such as dispersal ability and biotic interactions. Another potential source of model...

Williams C, Nicolai A, Ferguson L, Bernards M, Hellmann J, Sinclair B
Comp Biochem Physiol A Mol Integr Physiol . 2014 Aug; 178:51-8. PMID: 25139402
Seasonally-acquired cold tolerance can be reversed at warm temperatures, leaving temperate ectotherms vulnerable to cold snaps. However, deacclimation, and its underlying mechanisms, has not been well-explored in insects. Swallowtail butterflies...

ONeil S, Dzurisin J, Williams C, Lobo N, Higgins J, Deines J, et al.
Mol Ecol . 2014 Apr; 23(11):2686-98. PMID: 24766086
Local adaptation of populations could preclude or slow range expansions in response to changing climate, particularly when dispersal is limited. To investigate the differential responses of populations to changing climatic...
