Sentence examples for breeding population size from inspiring English sources

Comparative census estimates in Río Colorado indicated a 91.3percentnt decrease in the breeding population size after the catastrophe.

We documented changes in adult breeding population size based on annual censuses of egg masses.

Fecundity is strongly correlated with subsequent recruitment and is critical for maintaining breeding population size.

For R. aurora, one egg mass corresponds to one breeding female as multiple clutching is not known and unlikely to occur given oviposition seasonality (see Licht 1969, 1971); hence, egg mass numbers effectively estimate the breeding population size of females and are a good surrogate for breeding population size (e.g., Richter and Azous 2001).

Our spatial analysis revealed that the relationship between R. aurora breeding population size and percent forest becomes important at 200 m, peaks at 450 m, but remains high to 5 km which was the furthest distance examined in this study.

Since the correlation between breeding population size and percent forest becomes significant at 200 m, along with the marked increase in the correlation coefficient up to 450 m, this suggests that the forest habitat further from the wetlands maybe more important habitat for R. aurora during its migration than the forests bordering the wetlands.

Both the locally neutral and random draw models take as their major input estimates, gained through fieldwork, of the British breeding population sizes of those species present in the regional pool.

Every simulated generation, we used a simulated sample to calculate the number of fixed markers (out of 64), FLS, and X. Simulations were repeated 1,000 times for each of the 25 combinations of initial conditions and breeding population sizes.

Our results suggest that sample sizes of <700 are sufficient for achieving adequate (80%) statistical power when the rate of inbreeding is high (similar to that found in a randomly breeding population of size Ne = 100), such as could occur in samples selected on the basis of likely recent inbreeding or in small, isolated populations.

This ratio arises as the limiting value of the breeding ratio for a polygynous system where a single male has access to a female breeding population of infinite size [ 18].

In a breeding population of this size, genetic drift would be too slow to explain the observed in the relatively short time considered in this study (50 years or about 12 generations).
