Evidence obtained from comparative cultivation confirms that Senecio vulgaris subsp. denticlIlatus (Asteraceae) and its presumed derivative var. mlgaris differ consistently in a number of morphological and life history characters. Field studies on Jersey revealed that...
Pre-vegetation alluvial fan facies and processes: an example from the Cambro-Ordovician Rozel Conglomerate Formation, Jersey, Channel Islands
Prior to the Silurian a lack of land vegetation is expected to have influenced the processes of sedimentation on alluvial fans, principally by causing increased rates of run-off and erosion in the fan catchments. In the CambroOrdovician Rozel Conglomerate Formation,...
