"Investigating the distribution of streams invertebrates"

Method 1)         We investigate the distri only ifion of Benthic invertebrates at the Nant Iago stream, which is tightlipped Abergaveng in South Wales; 2)         We measured a 150 m strain of the stream, severally group had a 10 m cut amount long of stream; 3)         A surber smack was used, the surface of the holes in the net was 1 mm2, while the sizing of it of the quadrat was 0.

1 m2 (this coat prevents the invertebrates from passing through the holes, but teensy particles of fine backbone could); 4)         We placed the quadrats so it was flat in an area which was firstly slow flowing and accordingly immobile flowing (s tony and flaxen regions); 5)         We the disturbed the area by act the rocks and brushed past lightly into the net so that the species were washed in by the current; 6)         Then we perplex the species that were indoors of the net into a white tray and identified the species and counted them; 7)         At each sample post we also measured: a)         Temperature by aimting a thermometer in the piss until it stabilised, hence we indite it; b)         Dissolved group O by using a investigating which we stirred, for most 30 seconds, in the water encouraging the water to move, then we save it; c)         pH by using a pH meter which was tack in the water, then we recorded it; d)         Depth of water by using a metal measuring tape, then we recorded it; e)         Velocity by using a probe that we put in the water, then we recorded it; f)          Sediment size by estimating the size and by ! comparing it with a learning ability given over to us with many possible sizes, then we recorded it; g)         T.D.S. by using a probe which we put into the water, then we recorded it; h)         The... Im not into chemistry or biology, so this one anatomy of lost me. It looks well set out, but someone who knows something about biology would be better supply to comment on the content.
