PseudoBase: a genomic visualization and exploration resource for the Drosophila pseudoobscura subgroup. [PDF]
Drosophila pseudoobscura is a classic model system for the study of evolutionary genetics and genomics. Given this long-standing interest, many genome sequences have accumulated for D. pseudoobscura and closely related species D. persimilis, D.

A history of studies of reproductive isolation between Drosophila pseudoobscura and D. persimilis. [PDF]
Drosophila pseudoobscura and D. persimilis are a sister species pair that have been used as a model for studies of reproductive isolation and speciation for almost 100 years owing to their close evolutionary history, well characterized genetic ...

Intra-specific regulatory variation in Drosophila pseudoobscura. [PDF]
It is generally accepted that gene regulation serves an important role in determining the phenotype. To shed light on the evolutionary forces operating on gene regulation, previous studies mainly focused on the expression differences between species and ...

Assessment of rival males through the use of multiple sensory cues in the fruitfly Drosophila pseudoobscura. [PDF]
Environments vary stochastically, and animals need to behave in ways that best fit the conditions in which they find themselves. The social environment is particularly variable, and responding appropriately to it can be vital for an animal's success ...

Age-dependent male mating investment in Drosophila pseudoobscura. [PDF]
Male mating investment can strongly influence fitness gained from a mating. Yet, male mating investment often changes with age. Life history theory predicts that mating investment should increase with age, and males should become less discriminatory ...

Divergence of X-linked trans regulatory proteins and the misexpression of gene targets in sterile Drosophila pseudoobscura hybrids. [PDF]
Background The genetic basis of hybrid incompatibilities is characterized by pervasive cases of gene interactions. Sex chromosomes play a major role in speciation and X-linked hybrid male sterility (HMS) genes have been identified. Interestingly, some of

Extensive exchange of transposable elements in the <i>Drosophila pseudoobscura</i> group. [PDF]
Background As species diverge, so does their transposable element (TE) content. Within a genome, TE families may eventually become dormant due to host-silencing mechanisms, natural selection and the accumulation of inactive copies.

Testes Proteases Expression and Hybrid Male Sterility Between Subspecies of Drosophila pseudoobscura. [PDF]
Hybrid male sterility (HMS) is a form of postmating postzygotic isolation among closely related species that can act as an effective barrier to gene flow.

Chemical signals and social structures strengthen sexual isolation in Drosophila pseudoobscura. [PDF]
Species that coexist in hybrid zones sexually isolate through reproductive character displacement, a mechanism that favours divergence between species. In Drosophila, behavioural and physiological traits discourage heterospecific mating between species ...

Transcriptomic Analysis and Comparative Analysis of Gene Families Related to Environmental Adaptation in Two Grylloblattodea Species: <i>Galloisiana sinensis</i> and <i>Grylloprimevala jilina</i>. [PDF]
Notoptera, a singular ancient insect lineage, is vital for exploring insect environmental adaptation, evolution, and its geological history link, recognized as a national first‐class protected animal. Comparing environmental adaptation genes in Galloisiana sinensis and Grylloprimevala jilina, closely related yet habitat‐disparate species, illuminates ...
