In addition to aspects based on the test level, issues at the level of sample should also be addressed.
We recommend maintaining the level of sampling intensity for trap gear and increasing the sampling effort for trawl gear.
At the level of sample areas, a significant relationship between organic farming and landscape composition was only found for densities of small biotopes.
On the level of sample preparation for speciation analysis by GC-ICP MS, new derivatization reagents and advances in extraction techniques, such as capillary purge-and-trap, solid phase microextraction and stirbar solid phase extraction are discussed.
In the above and other surveys, it is typical to catch half of the species only once (and this does not seem to change with the level of sampling effort employed to date).
Given the level of sampling effort over the years, combined with the observed spatial extent and demographic data (size structure), it is improbable that established L. littorea populations would remain undiscovered for so long.
We used populations without any sub-level as the level of sampling in these analyses.
was relatively low, especially considering the level of sampling in those areas.
The accuracy of D-LBTE solvers depends on the material assignment and the level of sampling the structure voxels to the calculation grid.
