The evolutionary history of Drosophila buzzatii XXVII - Thorax length is positively correlated with longevity in a natural population from Argentina
The correlation between body size and longevity was tested in an Argentinian natural population of Drosophila buzzatii. Mean thorax length of flies newly emerging from rotting cladodes of Opuntia vulgaris was significantly smaller than that of two samples of flies caught at baits. The present result...
