2023年8月10日 · Genetic offset is an ecologically genomic approach that models the turnover of climate-associated genetic variation as a function of the climatic difference between populations 16.
Prospects and limitations of genomic offset in conservation …
2021年2月10日 · It is also known as genetic offset (Fitzpatrick & Keller, 2015), genomic vulnerability (Bay, Harrigan, Le Underwood, et al., 2018), or risk of nonadaptedness (Rellstab et al., 2016), but here we refer to "genomic offset" to emphasize its genomic perspective.
Landscape genomics predicts climate change‐related genetic offset …
2019年11月7日 · Based on current genetic–environmental associations and machine-learning-based modeling, we identified regions with high genetic offset in P. orientalis distribution range where genetic–environmental relationships are most likely to be disrupted under future climate conditions. Our analyses provide the first insight on diversity and ...
Incorporating adaptive genomic variation into predictive models …
2024年3月1日 · open access. Highlights. •. We found distinct risks using species distribution vs. gradient forest models. •. Habitat suitability change and genomic offset are functionally complementary. •. The genomic-niche index provides more comprehensive predictions of …
Seeing the forest for the trees: Assessing genetic offset …
2022年2月4日 · We evaluated offset measures under two genetic architectures: a single-locus population genetic model, and a multilocus two-trait quantitative genetic model. In both models, a migration rate of m = 0.2 was chosen, which allowed potentially adapted variants to quickly “encounter” their niche and allowed local adaptation to quickly arise ...
