In our study, we have identified several elements that are characteristic of an arms race: morphological variation among close relatives as well as a correlation between morphology and behavior.
We know the elements that are needed.
Are these elements that can be measured?
On the one hand, it is clear that rivers and bridges form important morphological elements, and they are clearly related to in various ways through history.
In particular, one characteristic of stress neighborhood, that up to now has not been investigated, is the fact that many stress neighborhood endings are formed by morphological elements.
"There are projects similar to previous ones," Herzog acknowledges, "but they are still experimentally interesting because they reveal other sides of morphological elements.
The morphological elements of the mask are with few exceptions derived from natural forms.
Slope units were found to be appropriate for the fundamental morphological elements in landslide susceptibility evaluation.
Morphological integration refers to the relationships and connections among morphological elements, and is empirically recognized by detecting the existence of discrete groups of highly correlated traits, termed modules.
We find that despite differences in phylogenetic composition, invasion history, and ecological setting, the three assemblages are diversifying along parallel axes through morphospace and have nearly identical variance-covariance structures among morphological elements.
