All the catch periods gives different results, which was confirmed by the test results,
unless in month 10 and 11 which were coinciding (Figure 10.3.4). The contribution
from each species to these differences is not described in the present note.

transformed data.
Figure 3.1.0.5 shows the result of the same ordination with signatures marking the two
areas. To facilitate the interpretation of the graph the samples have been separated into
each of the five sampling occasions. If the graphs are placed on top of each other they
will represent figure 3.10.4. A global permutation test shows significant areas if not
considering the times. If each sampling occasion is tested isolated in each period only
month 5 and 9 gives a significant difference between the areas.
