For each model, in addition to a standard OLS (mean) regression, we fit quantile regressions for percentiles from the 70th to the 99th.

Quantile regression was used to estimate effects of physical habitat resources on a bivalve (Koenker and Machado 1999, Cade 2003) suggest that weighted come; Koenker & Bassett, 1978).

Assume that the conditional quantile is given by the function f (τ |x) then for example for τ = 0.9, f (0.9|x) is the 90th percentile of the distribution of y conditional on the values of x i.e. The quantile regression models for the traits of major interest were fitted using the “rq()” function from the “quantreg” library (Koenker, 2017) for different quantile levels. As opposed to e.g. threshold-based indices, percentile-based indices are more comparable across different climatic regions. For each model, in addition to a standard OLS (mean) regression, we fit quantile regressions for percentiles from the 70th to the 99th.
