Sentence examples for breeding size from inspiring English sources

This is a highly skewed family representation of at least 748 dam x sire combinations with a low effective breeding size, which might affect the estimates through the unwanted genetic drift (or limited Mendelian sampling) caused by the skewed representation.

The results from our study document that such climate events significantly affect the effective breeding sizes of bird populations.

Ideally, wild stock structure, genetic diversity, historical and contemporary census and effective population sizes, and generation interval, as well as hatchery diversity, breeding effective size, and intended and realized contribution rates to the wild, would be known or inferable.

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).

Two females produced 27% of the seasonal offspring pool and female breeding effective size averaged 1.85 per spawn and 12.38 seasonally, whereas male breeding effective size was higher (6.42 and 20.87, respectively), with every male contributing 1 7% of offspring.

The simplest and most direct explanation is the aforementioned increase in breeding population size; declines in genetic variation are really only expected with declines in population size.

Although some attempts have been made to determine the relationship between breeding population size and genetic diversity (e.g., Maruyama and Fuerst 1985; Danusevicius and Lindgren 2005), empirical studies controlling the size of the breeding populations and documenting the selection intensity are still largely needed to confirm the nature of the occurring changes.

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.

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.
