Conservation of the behavioral and transcriptional response to social experience among Drosophilids
TLDR
Significant variability in the extent of aggressiveness, the utilization of social cues during food search, and social space preferences across species of Drosophilids is observed, supporting a growing body of evidence that behavioral evolution is driven by the differential regulation of this class of genes.
A Review of Nearctic Rove Beetles (Staphylinidae) Specialized on the Burrows and Nests of Vertebrates
TLDR
This review provides an overview of the rove beetles putatively specialized for life in burrows and nests in the Nearctic region, with a total of 46 species from 7 of the 25 Nearctic subfamilies known thus far.
Biology of Rove Beetles (Staphylinidae)
TLDR
Because of their worldwide distribution, their ecological significance, and their behavioral and ecomorphological diversity, staphylinids are nowadays becoming an increasingly investigated insect group in the fields of evolution and ecology.
Aggression and Mating Success in Three Species of Drosophila1
TLDR
The results indicated that the most important determinant of male mating success was not the amount of aggression performed by a male, but rather theamount of aggression directed towards him.
Ecological impact of beavers Castor fiber and Castor canadensis and their ability to modify ecosystems
TLDR
It is suggested that beavers can create important management opportunities in the Holarctic, and this review will help land man- agers determine the likely outcome of beaver activity.
Molecular evolution and phylogeny of theDrosophila virilis species group as inferred by two-dimensional electrophoresis
  • G. Spicer

    Journal of Molecular Evolution
  • 2005
TLDR
It appears that the evolution of the major clades within the species group occurred about 20 million years ago, and suggestions that the rate of molecular evolution was different between the virilis and montana phylads was not confirmed.
Pupation-temperature range in 12Drosophila species from different ecological backgrounds
TLDR
Comparisons of species' mating-, oviposition- and pupation-temperature ranges reveal that pupation most-often occurs at temperatures beyond those for mating and oviposing, and the evaluation of temperature effects on species, based on a single activity, may be adequate for predicting adaptive strategies.
High divergence of reproductive tract proteins and their association with postzygotic reproductive isolation in Drosophila melanogaster and Drosophila virilis group species
TLDR
It is suggested that the faster rate of evolution of gonadal proteins in comparison to nongonadal proteins and the association of that rate with postzygotic reproductive isolation may be the result of episodic and/or sexual selection on male and female molecular traits.
Strategic differences in thermal adaptation between two Drosophila species, D. virilis and D. immigrans
TLDR
Thermal adaptation of virilis seems to be based on the high tolerance to extreme temperatures and that of immigrans mainly on the behavioural preference for viable temperatures.

TLDR
This review concentrates on studies of protein evolution, and does not deal with protein variation within populations, which has been much reviewed recently (35, 52, 62).
