data(chevan)urbanwq.txt
Seven catchment variables (fimp, catchment imperviousness\(^{0.25}\); sconn, drainage connection\(^{0.5}\); sdensep, septic tank density\(^{0.5}\); unsealden, unsealed road density; fcarea, catchment area\(^{0.25}\); selev, elevation\(^{0.5}\); amgeast, longitude) and median baseflow concentrations of three water quality variables in sixteen streams draining 16 independent subcatchments (ldoc, log(dissolved organic carbon); lec, log(electrical conductivity); lnox, log(nitrate/nitrite). Data from Hatt et al. (2004).
amphipod.txt
Presence-absence data for a stream-dwelling amphipod (Austrogammarus australis) in 58 sites, with four catchment variables (fimp, imperviousness\(^{0.25}\);fconn, drainage connection\(^{0.25}\); densep, density of septic tanks; unseal, unsealed road density). Data from Walsh et al. (2004).
