Sentence examples for be difficult to delimit from inspiring English sources

Though levels of selection may be difficult to delimit, conceptually they are discrete.

At ground level it is difficult to delimit the landslide complex but using satellite imagery and digital elevation models the landslide location and volume can be estimated.

Despite these advances, the precise subcellular structures involved in the induction and expression of LTP have been difficult to delimit with current approaches because experiments in brain slices and cultured neurons cannot definitively localize these processes, as they do not disrupt the connections between spines and adjacent structures.

Journals delimit their respective scopes and styles (through intentional choices, self-organization and competition) so that it might be difficult to publish articles that do not fall within one of the categories journals have created.

Cladogenic events occurring more recently than this are expected to be increasingly difficult to delimit for two reasons: they are more likely to yield species that are not monophyletic and thus impossible to accurately identify under this model, and the most recent common ancestor (MRCA) of the daughter species is more likely to occur more recently than the threshold point.
