Abstract
There was a typographical error in the title and citation. The correct title is: Phenology of Scramble Polygyny in a Wild Population of Chrysomelid Beetles: The Opportunity for and the Strength of Sexual Selection. The correct citation is: Baena ML, Macias-Ordonez R (2012) Phenology of Scramble Polygyny in a Wild Population of Chrysomelid Beetles: The Opportunity for and the Strength of Sexual Selection. PLoS ONE 7(6): e38315. doi:10.1371/journal.pone.0038315
Highlights
What should we expect from an estimate of the strength or intensity of sexual selection? The answer clearly depends on the assumptions behind each estimate and on the data we use, which in turn depend on the ecological context of the population
The resources that promote aggregation of potential mates in space or time should have a strong effect on the reproductive strategies of a population. Ecological factors such as food availability or oviposition sites, among others, may influence female aggregation patterns and distribution of reproductive success among males [3,4] which will all impact the upper limit for the strength of sexual selection, i.e., the opportunity for sexual selection (Is or Imates), which in itself is a useful descriptor of the mating system and the potential for sexual selection to act on one or many phenotypic traits
A marked temporal variation could be observed even in basic descriptive parameters such as copulas per male or overall abundance (Figures 2 and 3). These parameters started at intermediate values in period 1, peaked in period 2, returned to intermediate values in period 3, and collapsed in period 4

The resources that promote aggregation of potential mates in space or time should have a strong effect on the reproductive strategies of a population Ecological factors such as food availability or oviposition sites, among others, may influence female aggregation patterns and distribution of reproductive success among males [3,4] which will all impact the upper limit for the strength of sexual selection, i.e., the opportunity for sexual selection (Is or Imates), which in itself is a useful descriptor of the mating system and the potential for sexual selection to act on one or many phenotypic traits (for a recent debate on this see [2,5,6]). The opportunity for, sexual selection may provide different and potentially complementary information on the reproductive ecology of the population, but they have rarely been compared or contrasted on the same wild population
