Patterns of Gene Family Evolution and Selection Across Daphnia

open access: yesEcology and Evolution, Volume 15, Issue 5, May 2025.
This study examines gene family dynamics within Daphnia species, using comparative genomics to explore adaptive expansion in gene families, particularly those related to stress response. Findings reveal general trends in gene turnover and selection, although most changes are species‐specific, highlighting complex evolutionary patterns.

Metaphase Configurations in Drosophila: A Comparison of Endemic Hawaiian Species and Non-Endemic Species [PDF]

open access: yes, 1976
The metaphase configurations of 400 strains from 63 species of Hawaiian Drosophila were determined from squash preparations of larval brain tissue or spermatogenic cells from adult testes.

Principles of genome evolution in the Drosophila melanogaster species group. [PDF]

open access: yes, 2007
That closely related species often differ by chromosomal inversions was discovered by Sturtevant and Plunkett in 1926. Our knowledge of how these inversions originate is still very limited, although a prevailing view is that they are facilitated by ...

Carrion‐breeding flies of Australia and New Zealand: A review and key to adults

open access: yesAustral Entomology, Volume 64, Issue 2, May 2025.
Abstract Carrion‐breeding flies are diverse with over 70 species in the Australasian/Oceanian region, predominantly from the families Calliphoridae and Sarcophagidae. These flies play crucial roles in ecosystems as primary decomposers, pollinators and food sources for a variety of predators and parasites.

Taxonomic and evolutionary analysis of Zaprionus indianus and its colonization of Palearctic and Neotropical regions

open access: yesGenetics and Molecular Biology, 2012
Zaprionus indianus is a dipteran (Drosophilidae) with a wide distribution throughout the tropics and temperate Palearctic and Nearctic regions. There have been proposals to reclassify the genus Zaprionus as a subgenus or group of the genus Drosophila ...

Conservation of nuclear SSR loci reveals high affinity of Quercus infectoria ssp. veneris A. Kern (Fagaceae) to section Robur [PDF]

open access: yes, 2013
Conservation of 16 nuclear microsatellite loci, originally developed for Quercus macrocarpa (section Albae), Q. petraea, Q. robur (section Robur) and Q. myrsinifolia, (subgenus Cyclobalanopsis) was tested in a Q. infectoria ssp. veneris population from Cyprus.

Inferring Network Mechanisms: The Drosophila melanogaster Protein Interaction Network [PDF]

open access: yesPNAS, Vol. 102, No. 9, pp. 3192-3197 (March 1, 2005), 2004
Naturally occurring networks exhibit quantitative features revealing underlying growth mechanisms. Numerous network mechanisms have recently been proposed to reproduce specific properties such as degree distributions or clustering coefficients.

DNA from museum samples of a parasitoid wasp genus (Braconidae: Syntretus) offers novel insights into host‐parasitoid interactions

open access: yesInsect Conservation and Diversity, Volume 18, Issue 3, Page 319-329, May 2025.
Our investigation applied genome skimming to museum specimens of Syntretus, a parasitoid wasp, due to its suspected parasitism of short‐haired bumblebee (Bombus subterraneus) queens during a reintroduction programme. We detected two clades within Syntretus, a possible consequence of host choice.

The evolution of olfactory gene families in Drosophila and the genomic basis of chemical-ecological adaptation in Drosophila suzukii [PDF]

open access: yes, 2016
How the evolution of olfactory genes correlates with adaption to new ecological niches is still a debated topic. We explored this issue in Drosophila suzukii, an emergin gmodel that reproduces on fresh fruit rather than in fermenting substrates likemost ...
