The Compressibility of Media under Extreme Pressures
Open accessAbstract
With the exception of the Teffe strain which will be dis- cussed in another publication, no trace of sexual isolation is observed between strains of D. willistoni from different parts of Brazil and from Guatemala.When Brazilian males are offered a choice of females of their own and of other Brazilian strains, inseminations occur at random.If a mixture of Brazilian and Guatemalan females are confined either with Brazilian or with Guatemalan males, a greater proportion of Brazilian than of Guatemalan females are inseminated.The mating of Brazilian and Guatemalan flies is, therefore, selective rather than random; however, the particular type of selectivity here observed does not constitute a barrier to gene exchange.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
