This occurs when the difference between female and male dispersal distance is sufficiently large to drive sex ratios at newly colonized locations beyond thresholds for population increase. Second, for invasions that spread, sex-biased dispersal can accelerate range expansion (relative to unbiased ...

As shown in Extended Data Fig. 2, the results agree with the expected ratios 1:0.75:0.25 and are consistent with a negligible contribution of non-P1 defects to the DEER signal. Sample S2 A detailed characterization of the three-dimensional sample S2 is given in ref. 24 (sample C041). ...
Sex ratios (± 95% credible intervals) of completely genotyped clutches with (black circles) and without extra-pair paternity (open circles) and among all extra-pair and within-pair offspring in (a) black coucals and (b) white-browed coucals. In both coucal species the sex ratios of clut...
The latter has been seen in Australasian gannets (Morus serrator) for example, where males consistently consumed a diet that had higher protein-to-lipid ratios compared to their female counterparts, possibly in response to sex-specific nutrient requirements26. Although these studies have documented ...
Bubble flow: This is prevalent at high ratios of liquid flow rate to gas flow rate. The gas is dispersed as bubbles which move at a velocity similar to the liquid and tend to concentrate near the top of the tube at lower liquid velocities. 9. Plug flow: Alternate plugs of gas and liq...

We report odds ratios (ORs) because they are easier to interpret than slope coefficients (Long, 1997). ORs higher than 1 indicate higher odds, and values lower than 1 indicate lower odds for the criterion (Long, 1997). ORs indicate the change in the ratio of the odds of majoring in a...
