The heritability of mating behaviour in a fly and its plasticity in response to the threat of sperm competition.

open access: yesPLoS ONE, 2014
Phenotypic plasticity is a key mechanism by which animals can cope with rapidly changeable environments, but the evolutionary lability of such plasticity remains unclear.

Drosophila Sexual Attractiveness in Older Males Is Mediated by Their Microbiota

open access: yesMicroorganisms, 2020
Age is well known to be a basis for female preference of males. However, the mechanisms underlying age-based choices are not well understood, with several competing theories and little consensus.

Genome-wide tests for introgression between cactophilic Drosophila implicate a role of inversions during speciation [PDF]

open access: yes, 2015
K.L. was funded by a junior research fellowship from the National Environmental Research Council, UK (NE/I020288/1, NBAF659).Models of speciation-with-gene-flow have shown that the reduction in recombination between alternative chromosome arrangements ...

The Functions of the Multiproduct and Rapidly Evolving \u3cem\u3edec-1\u3c/em\u3e Eggshell Gene Are Conserved Between Evolutionarily Distant Species of Drosophila [PDF]

open access: yes, 2001
The Drosophila dec-1 gene encodes multiple proteins that are required for female fertility and proper eggshell morphogenesis. Genetic and immunolocalization data suggest that the different DEC-1 proteins are functionally distinct.

MicroRNA targets in Drosophila. [PDF]

open access: yes, 2003
BACKGROUND: The recent discoveries of microRNA (miRNA) genes and characterization of the first few target genes regulated by miRNAs in Caenorhabditis elegans and Drosophila melanogaster have set the stage for elucidation of a novel network of regulatory ...

Preadult competition between Drosophila subobscura and Drosophila pseudoobscura

open access: yesJournal of Zoological Systematics and Evolutionary Research, 2009
The Palaearctic species Drosophila subobscura has recently colonized a large area of North America where it coexists with Drosophila pseudoobscura. The viability and developmental rate of these species were studied at 13 dC, 18dC and 23 dC and at densities of 10, 50, 100 and 200 eggs per vial.

PATTERN OF CHROMOSOME VARIABILITY IN DROSOPHILA PSEUDOOBSCURA [PDF]

open access: yesEvolution, 1960
It has been noted by several investigators (Dobzhansky 1944; Novitski 1946; Pavan 1946) that in some species of Drosophila, variability in chromosome structure is virtually restricted to one chromosome. At the same time, they note, the variable chromosome has a large number of inversions distributed throughout the species. This paper shall be addressed

Chromatographic separation and identification of some peptides in partial hydroylsates of gelatin [PDF]

open access: yes, 1953
Recently we have been engaged in a study of the chemical structure of collagen and gelatin with the object of determining the sequence of the amino acid residues in the polypeptide chains of these proteins.

Gene expression clines reveal local adaptation and associated trade-offs at a continental scale [PDF]

open access: yes, 2016
Local adaptation, where fitness in one environment comes at a cost in another, should lead to spatial variation in trade-offs between life history traits and may be critical for population persistence.

Decoding transcription and microRNA-mediated translation control in Drosophila development [PDF]

open access: yes, 2010
The spatio-temporal regulation of gene expression lies at the heart of animal development. In this article we present an overview of our recent work to apply systems biological approaches to the study of transcription and microRNA-mediated translation ...
