Differential attraction of drosophilids to banana baits inoculated with Saccharomyces cerevisiae and Hanseniaspora uvarum within a Neotropical forest remnant [PDF]

PeerJ, 2017
Background Yeasts are a necessary requisite in the diet of most Drosophila species that, in turn, may vector their dispersal in natural environments.

Ecology and Diversity of Urban <i>Drosophila</i> Species Communities as Potential Indicators of Biodiversity Decline. [PDF]

Ecol Evol
We investigated urban Drosophila communities in Vienna using ~18,000 specimens collected with citizen scientists, identifying 13 species including two new records for Austria (D. mercatorum and D. virilis). Compared to surveys 30 years ago, species richness has declined by more than 50%, with formerly common species replaced by neobiotic taxa.

Phylogenomics reveals the evolution of floral traits associated with pollinators and pollinator-prey conflict within the carnivorous Pinguicula subgenus Temnoceras. [PDF]

Am J Bot
Abstract Premise The carnivorous plant genus Pinguicula (Lentibulariaceae) exhibits remarkable floral diversity associated with pollination, particularly in the largest subgenus Temnoceras, which spans Mexico and Central America. Despite this diversity, the relationships between species and the evolution of key floral traits remain unresolved. Here, we

Divergent Transcriptional Architectures Beyond Core CAM Genes in Facultative and Constitutive CAM Species in Tillandsia L. [PDF]

Mol Ecol
ABSTRACT Crassulacean acid metabolism (CAM) is a water‐efficient photosynthetic strategy involving a coordinated suite of complex traits including metabolic, anatomical and regulatory aspects that shift across the diel cycle. While CAM has evolved repeatedly in land plants, the evolutionary routes enabling this convergence remain elusive.

IbinA and IbinB regulate the Toll pathway-mediated immune response in Drosophila melanogaster [PDF]

BMC Biology
Background To combat infection, an immune system needs to be promptly activated but tightly controlled to avoid destruction of host tissues. IbinA and IbinB are related short peptides with robust expression upon microbial challenge in Drosophila ...

Characterization of the chemoreceptor repertoire of a highly specialized fly with comparisons to other Drosophila species [PDF]

Genetics and Molecular Biology
To explore the diversity of scenarios in nature, animals have evolved tools to interact with different environmental conditions. Chemoreceptors are an important interface component and among them, olfactory receptors (ORs) and gustatory receptors (GRs ...

Phylogeography of the Subgenus Drosophila (Diptera: Drosophilidae): Evolutionary History of Faunal Divergence between the Old and the New Worlds. [PDF]

PLoS ONE, 2016
The current subgenus Drosophila (the traditional immigrans-tripunctata radiation) includes major elements of temperate drosophilid faunas in the northern hemisphere.

A comparative study of the short term cold resistance response in distantly related Drosophila species: the role of regucalcin and frost. [PDF]

PLoS ONE, 2011
The molecular basis of short term cold resistance (indexed as chill-coma recovery time) has been mostly addressed in D. melanogaster, where candidate genes (Dca (also known as smp-30) and Frost (Fst)) have been identified.

Phylogenetic patterns of geographical and ecological diversification in the subgenus Drosophila. [PDF]

PLoS ONE, 2012
Colonisation of new geographic regions and/or of new ecological resources can result in rapid species diversification into the new ecological niches available. Members of the subgenus Drosophila are distributed across the globe and show a large diversity

Functional olfactory evolution in Drosophila suzukii and the subgenus Sophophora

iScience, 2022
Summary: Comparative analyses of multiple genomes are used extensively to examine the gains and losses of chemosensory receptors across the genus Drosophila. However, few studies have delved into functional olfactory characteristics.
