P-waves are longitudinal waves similar to sound waves; they propagate at the speed of sound and have large ranges.
They also have large ranges, inhabit areas with few other rodent species as neighbours, and (not surprisingly) live near big human populations.
In living mammals, there tend to be relatively few large species, and they have large ranges.
Because ecological traits are characterized by a disconnect between the metric measured and the mechanisms that would underlie response to the 'trait', trait values for some groups of species will necessarily be unconstrained and have large ranges.
Moreover, they have large ranges, often spanning waters belonging to more than one nation, so efforts to protect them require international coordination.
Note 2: No perfect score defined for Performance indicator BC 4. All PIs have high averages (ceiling effect; see Table 2) and PIs 4b (2008, 2009, 2010) and 5c (2008) have large ranges, from 0%to100%0%to100%
Limited data from shallow water nematodes indicates that some nematode species have large ranges [ 16, 17], but it is unknown whether or not deep-sea taxa possess similar dispersal capabilities.
The US population in general also may have larger range in income levels compared to the Danish population where the progressive taxation policy means that few are very rich and few are very poor.
Older species pairs with larger range sizes and/or larger body size were expected to more likely have larger range size contrasts and larger body size contrasts, accounting for the possibility of (potentially asymmetric) post-speciation range shifts or range size changes.
One is that the vast majority of Apple products are made by one company, Foxconn, where most computer companies have larger ranges made by perhaps half a dozen different contract manufacturers.
