To investigate patterns of gender-based performance gaps, we conducted a meta-analysis of published studies and unpublished data collected across 169 undergraduate biology and chemistry courses. While we did not detect an overall gender gap in perfor

Wolbachiais a genus of intracellular alpha-Proteobacteria that is maternally inherited and is capable of inducing a variety of reproductive alterations in host species. The host range ofWolbachiais not determined completely but is known to contain a

Stable isotope analysis (SIA) has proven to be a useful tool in reconstructing diets, characterizing trophic relationships, elucidating patterns of resource allocation, and constructing food webs. Consequently, the number of studies using SIA in trop

We ask whether the observed mitochondrial DNA (mtDNA) population subdivision of Drosophila simulans is indicative of organismal structure or of specific processes acting on the mitochondrial genome. Factors either intrinsic or extrinsic to the host g

Selection experiments with Drosophila have revealed constraints on the simultaneous evolution of life history traits. However, the responses to selection reported by different research groups have not been consistent. Two possible reasons for these i

We investigated the cellular basis of two extensive, continuous, latitudinal, genetic, body size clines of Drosophila melanogaster by measuring wing area and cell size in the wing blade of adult flies reared under standard, laboratory conditions. We

Wolbachia , a bacterial endosymbiont of diverse arthropods, affects its host's reproduction and so is consequential for its host's fitness. In the fruit fly Drosophila simulans, Wolbachia increases embryonic mortality in crosses of infected males wit

In dipterans, the wing-beat frequency, and, hence, the lift generated, increases linearly with ambient temperature. If flight performance is an important target of natural selection, higher wing:thorax size ratio and wing-aspect ratio should be favor

The duration of Drosophila melanogaster larval and pupal periods was measured in laboratory thermal lines and in populations collected along a latitudinal transect in eastern Australia. In replicated laboratory lines kept for 9 years at 16.5 degrees

Reproductive isolation and morphological differences among allopatric populations of the Holarctic species Drosophila testacea v. Roser indicate that this taxon is actually a complex of three morphocryptic species: D. testacea , from Europe and conti
