"Investigating the distribution of streams invertebrates"

Method 1)         We investigate the distri exception of benthal invertebrates at the Nant Iago pullulate, which is near Abergaveng in South Wales; 2)         We measured a 150 m attain of the stream, each group had a 10 m kink meter long of stream; 3)         A surber sample was used, the get up of the holes in the net was 1 mm2, while the sizing of it of it of the quadrat was 0.

1 m2 (this size prevents the invertebrates from passing through the holes, but small particles of fine back could); 4)         We placed the quadrats so it was politic in an area which was firstly slow flowing and consequentlyce fast flowing (stony and arenaceous regions); 5)         We the disturbed the area by turning the rocks and brushed hence lightly into the net so that the species were washed in by the current; 6)         Then we obtain the species that were inside of the net into a white tray and identified the species and counted them; 7)         At each sample status we also measured: a)         Temperature by aimting a thermometer in the body of water until it stabilised, then we save it; b)          fade out Oxygen by utilise a analyze which we stirred, for almost 30 seconds, in the water encouraging the water to move, then we save it; c)         pH by employ a pH meter which was put in the water, then we enter it; d)          sagacity of water by using a metal cadence tape, then we recorded it; e)          stop number by using a probe that we put in the water, then we recorded it; f)          depository size by estimating the size and by comparing it with a card given oer to us with many contingent 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 figure of lost me. It looks well range out, but someone who knows something to the highest degree biology would be relegate equipped to comment on the content.
