Non-native cover declined three- to six-fold between the two sampling dates.
Factor scores also revealed considerable differences between the two sampling campaigns at individual sampling points.
The regression equations were not significantly different between the two sampling periods of 2001 to 2007 and 2008 to 2010 (F test; p =0.107).
Groundwater in the Albian aquifer of Oued Righ shows a change in its chemical properties between the two sampling periods, resulting from water-rock interactions and mixing processes.
However, even if this dominant driver was discounted, clear differences remained in APP abundance and physicochemical variables between the two sampling stations utilizing a seasonal referential time frame.
Whereas after oral administration such parameters derived for both drugs were largely comparable between the two sampling sites and statistically non-significant.
The results indicated the lack of pronounced differences in the regressions between the two sampling designs, although the sample size had a great impact on the regression outcome.
The overall faecal prevalence of E. hessei was 42% (range: 0% 80%) and did not differ between the two sampling sessions.
For PBDEs, the rise of mean concentrations between Düsseldorf and Rees is a result of the load of the River Lippe, which reaches the Rhine between the two sampling sites.
A paired t-test comparing the EAGB of trees with a DBH ≥ 60 cm from the census and inventory detected a significant difference between the two sampling protocols (n = 366, p < 0.01).
What are the patterns of wood density variability at the CA-level and between data produced by the census and inventory (i.e. sampling protocols)?; What is the variability of estimated AGB within and among CAs?; Do estimated AGB values differ between the two sampling protocols?
