The incidence of reproductive diapause is a critical aspect life history in overwintering insects from temperate regions. Much has been learned about the timing, physiology and genetics range insects, but how multiple changes involved this other photoperiodically regulated traits are interrelated not well understood. We performed quasinatural selection on reproduction under short photoperiods northern fly species, Drosophila montana, to trace effects photoperiodic by timer / or circadian...

Host-associated races of phytophagous insects provide a model for understanding how adaptation to new environment can lead reproductive isolation and speciation, ultimately enabling us connect barriers gene flow adaptive causes divergence. The pea aphid (Acyrthosiphon pisum) comprises host specializing on legume species provides unique system examining the early stages diversification along gradient genetic associated As choice produces assortative mating, underlying mechanisms will...

Abstract The diversity of phytophagous insects is largely attributable to speciation involving shifts between host plants. These are mediated by the close interaction and plant metabolites. However, there has been limited progress in understanding chemical signatures that underlie preferences. We use pea aphid ( Acyrthosiphon pisum ) address this problem. Host-associated races discriminate species race-specific ways. combined metabolomic profiling multiple with behavioural tests on two A ....

Abstract Phenotypic variation within species can affect the ecological dynamics of populations and communities. Characterizing genetic underlying such effects help parse roles evolution plasticity in “eco-evolutionary dynamics” inform how may shape patterns evolution. Here, we employ genome-wide association (GWA) methods Timema cristinae stick insects their co-occurring arthropod communities to identify associated with community-level traits. Previous studies have shown that maladaptation...

Abstract Alternative splicing, in which one gene produce multiple transcripts, may influence how adaptive genes respond to specific environments. A newly produced transcriptome of Drosophila montana shows the Gs1-like ( Gs1l ) express splice variants and be down regulated cold acclimated flies with increased tolerance. Gs1l’s effect on tolerance was further tested by injecting non-acclimated from two distantly located northern southern fly populations double stranded RNA (dsRNA) targeting ....
