Relative Abundance of Wild Ducks at Delavan, Wisconsin

The relative protein abundance

Estimation of European wild boar relative abundance and aggregation: a novel method in epidemiological risk assessment.

Wild boars are important disease reservoirs. It is well known that abundance estimates are needed in wildlife epidemiology, but the expense and effort required to obtain them is prohibitive. We evaluated a simple method based on the frequency of faecal droppings found on transects (FBII), and developed a spatial aggregation index, based on the runs test statistic. Estimates were compared with h...

Relative Factor Abundance and Trade

I develop a factor content of trade prediction for the Heckscher-OhlinVanek model (HOV) that relates bilateral differences in country endowments to bilateral differences in factor contents. The results are striking. In comparisons of North-South factor contents or factor contents of countries with very different endowments (e.g., with very different capital-labor ratios), there is clear support...

Statistical mechanics of relative species abundance

Statistical mechanics of relative species abundance (RSA) patterns in biological networks is presented. The theory is based on multispecies replicator dynamics equivalent to the LotkaVolterra equation, with diverse interspecies interactions. Various RSA patterns observed in nature are derived from a single parameter related to productivity or maturity of a community. The abundance distribution ...
