  4. 8. Palaeoenvironments of the Earliest (Middle Devonian) Tetrapod Trackways from the Holy Cross Mountains, Poland; Locomotion in a Terrestrial Setting?

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Martin Qvarnström; [2015]
    Keywords : Tetrapods; palaeoenvironment; trackways; paleosols; microfacies; trace fossils; fin-limb transition; Holy Cross Mountains.;

  6. 10. Catchment factors affecting particle and phosphorus retention in constructed wetlands receiving agricultural runoff

    University essay from Biologi; Tekniska högskolan

    Author : Anna Senior; [2012]
    Keywords : Agricultural runoff; Catchment characteristics; Clay; Constructed wetlands; GIS; Phosphorus retention;

    Abstract : Eight agricultural catchments in south Sweden were investigated for factors that may affect phosphorus (P) load and retention in the downstream situated wetlands (WL). P load is known to affect retention, and is determined by hydrological and geographical catchment characteristics. The wetlands were small (0.02-0. READ MORE
