| Footage description: | Aerial shots of the ICI research station at Jealott's Hill, Berks. Commentary by Mary Bell introduces the programme. The programme will examine some of the ways in which ecological samples are taken in the field. Mary Bell introduces Mike Morris and Jim Newman who will discuss and demonstrate their methods of ecological sampling. Jim Newman discusses his reasons for taking soil samples to study the effect of pesticides on soil micro-arthropod life. Shots of Jim Newman and assistant drilling for core soil samples. Jim Newman demonstrates the removal of microarthropod life from soil samples using the McFadion High Gradient Extraction Apparatus. Commentary explains how the apparatus works. Newman discusses some of the drawbacks of this apparatus. Newman next demonstrates and explains the Flotation Separation method of extracting micro-arthropods from soil samples. Walter Wilkinson demonstrates and explains a method of flotation separation which separates micro-arthropods from plant life in the sample. Jim Newman demonstrates and explains his technique for identifying and counting microarthropods in the sample. Newman then discusses some of the drawbacks of the Flotation Separation extraction method. |
