As in the case of differential reproduction, differential longevity of species (i.e., longer duration before extinction based on particular characteristics) can generate large-scale trends over long time periods as species with this characteristic persist and become more abundant whereas those lacking it disappear more quickly (Fig. 13d).
The minimal topological features of these biochemical networks provide distinct and robust mechanisms for integrating signals that persist with different characteristic time scales.
Nevertheless, many rural and cultural landscape characteristics persist, and past uses continue to have a significant impact on future landscape development.
To ensure that snags of appropriate characteristics persist for these two species of Myotis, forest managers in the northern Great Lakes forest region should retain, and manage for, large white pine (Pinus strobus) and trembling aspen (Populus tremuloides) snags at sites in forests that meet these criteria.
This region was industrialized 30 years ago, but transition areas with rural characteristics persist in the peripheral area of its cities.
The near-perfect prediction of in vivo grade from in vitro morphology, in spite of limited data, supports our assumption that morphological characteristics persist across sampling and systems.
We find that birth region and mother's educational attainment shape obesity risk among women, but not men; and that the effects of these characteristics persist among women from late-middle age (ages 50 61) to late life (ages 66 77).
He's guarded about his personal life (beyond remarking that "I actually live a quite normal life, but... for a foetus"), but rumours persist that behind the characteristic breathy and high-pitched delivery of Emo Philips there is a gentleman called Phil Soltanek, who has been inhabiting this character since the early 1970s.
Both aboriginal groups had brown complexion, blue or gray eyes, and blondish hair, and these characteristics still persist in a large number of present inhabitants of the islands, but otherwise they are scarcely distinguishable in appearance or culture from the people of Spain.
They come to play a protective role in later mythology, although some of their inauspicious and wild characteristics still persist in these accounts.
The visible dsRNA foci in TDP-43 knockout/knockdown likely contain only a sub-population of accumulating dsRNA molecules that are retained (or persist) due to innate characteristics of those transcripts.
