data for: Hybrid breakdown is elevated near the historical cores of a species' range

<p>Data and code for the manuscript:&nbsp;Accumulation of hybrid incompatibilities reflects neutral genetic structure more strongly than climatic differentiation</p> <p>&nbsp;</p> <p>F1 and F2 fitness data from within and between population crosses of Campanula americana are in F1_fitness.xls and F2_fitness.xls files, respectively. Data used for multiple linear regression testing the effects of neutral genetic and climatic differentiation on hybrid breakdown are in multipleReg_input.xls. Prism climatic data used to calculate Mahalonobis environmental distances are in prism_annual.xls.&nbsp;</p> <p>Code for resampling fitness data to calculate standard deviation of hybrid breakdown within hybrid crosses is provided in &#39;resample_fitness.R&#39;. Code for the mutliple linear regression is provided in &#39;multipleReg_code.R&#39; and code to calculate Mahalanobis D are in &#39;Mahalanobis_Env_D.R&#39;.</p>
