Sentence examples for shape of populations from inspiring English sources

It is also possible to show that the relationship we report is not an artefact caused by differences in the demographic shape of populations between short- and long-lived mammals.

Later, Crone [32] presented a nondelayed model and revealed that the inclusion of delays changes the shape of population cycles (flip versus Hopf bifurcations) and decreases the range of parameters which were used to predict stable equilibria.

Moreover, the logistic shape of population growth curve suggests a high level of competition between disperser offspring.

Third, Bayesian skyline plots implemented in BEAST v 1.4.8 [ 103] were constructed to estimate the shape of population growth through time with 300 million of iterations.

To estimate the shape of population growth through time for the individuals distributed along the ice sheet coverage area during the LGM, we constructed Bayesian skyline plots implemented in BEAST v 1.4.8 [ 69].

This has some implications for the general shape of genetic response that can be expected relative to the shape of population decline- almost certainly the curves will not be of the same shape, and genetic erosion will not be proportional to population loss (see also Nei 1975).

However, there is still much to be learned to better understand the mechanisms and their interactions that shape responses of populations facing environmental change.

Roach from the lake with highest predation pressure were most divergent from the average body shape of all populations, characterized by a more streamlined body and caudally inserted dorsal fins; features that facilitate predator escape.

Even in the absence of restricted gene flow, multiple unrelated founding events could also shape the same pattern of population genetic structure [ 4].

The age and sex structure of the population determines the ultimate shape of a population pyramid, such that the representation may take the form of a pyramid, have a columnar shape (with vertical sides rather than sloped sides), or have an irregular profile.

Although Tajima's D, Fu's F and mismatch distributions can provide insight into whether or not populations have undergone changes in population size, they do not provide information about the shape of the population growth over time.
