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 (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).
