The Pre-Jurassic Surface of Montana.
No full textIt has long been known that, prior to the deposition of Jurassic sediments, Montana was subjected to an intensive period of erosion. Mention of this may be found in numerous reports, especially those dealing with western Montana
Sexual and postmating reproductive isolation between allopatric Drosophila montana populations suggest speciation potential
No full textThis work was funded by a European Commission Research Training Grant RTN2-2001-00049, the Centre of Excellence for Evolutionary Research at the University of Jyväskylä and a Marie Curie Initial Training Network, ‘Understanding the evolutionary origin of biological diversity’ (ITN-2008-213780 SPECIATION)Background: Widely distributed species with populations adapted to different environmental conditions can provide valuable opportunities for tracing the onset of reproductive incompatibilities and their role in the speciation process. Drosophila montana, a D. virilis group species found in high latitude boreal forests in Nearctic and Palearctic regions around the globe, could be an excellent model system for studying the early stages of speciation, as a wealth of information concerning this species' ecology, mating system, life history, genetics and phylogeography is available. However, reproductive barriers between populations have hereto not been investigated. Results: We report both pre- and postmating barriers to reproduction between flies from European (Finnish) and North American (Canadian) populations of Drosophila montana. Using a series of mate-choice designs, we show that flies from these two populations mate assortatively (i.e., exhibit significant sexual isolation) while emphasizing the importance of experimental design in these kinds of studies. We also assessed potential postmating isolation by quantifying egg and progeny production in intra-and interpopulation crosses and show a significant one-way reduction in progeny production, affecting both male and female offspring equally. Conclusion: We provide evidence that allopatric D. montana populations exhibit reproductive isolation and we discuss the potential mechanisms involved. Our data emphasize the importance of experimental design in studies on premating isolation between recently diverged taxa and suggest that postmating barriers may be due to postcopulatory-prezygotic mechanisms. D. montana populations seem to be evolving multiple barriers to gene flow in allopatry and our study lays the groundwork for future investigations of the genetic and phenotypic mechanisms underlying these barriers.Peer reviewe
Campaign speech at Shelby, Montana, October 1952
No full textRepresentative Mansfield gives some biographical information about himself. He also discusses the economic status of Montana, the issues of the 1952 Montana Senatorial campaign, e. g. corruption, communism, and the need for the United States to remain strong in world politics.

A Listing of Montana Invertebrate Fossils and a Bibliography of Montana Paleontology
No full textThe oldest system in which identifiable invertebrate fossils have been found is the Cambrian. The basal Cambrian formation found in Montana is the Flathead sandstone and quartzite of Middle Cambrian age. No fossils have been reported from this formation. Above the Flathead is the Wolsey formation composed of green fissile shale with sandy and limy members. This fossiliferous member of the Middle Cambrian is known in Northwestern Montana as Gordon, and in the Philipsburg quadrangle as the Silver Hill formation
Sexual selection on song and cuticular hydrocarbons in two distinct populations of Drosophila montana
No full textSexual selection has the potential to contribute to population divergence and speciation. Most studies of sexual selection in Drosophila have concentrated on a single signaling modality, usually either courtship song or cuticular hydrocarbons (CHCs), which can act as contact pheromones. We have examined the relationship between both signal types and reproductive success using F1–3 offspring of wild- collected flies, raised in the lab. We used two populations of the Holarctic species Drosophila montana that represent different phylogeographic clades that have been separate for ca. 0.5 million years (MY), and differ to some extent in both traits. Here, we characterize the nature and identify the targets of sexual selection on song, CHCs, and both traits combined within the populations. Three measures of courtship outcome were used as fitness proxies. They were the probability of mating, mating latency, and the production of rejection song by females, and showed patterns of association with different traits that included both linear and quadratic selection. Courtship song predicted courtship outcome better than CHCs and the signal modalities acted in an additive rather than synergistic manner. Selection was generally consistent in direction and strength between the two populations and favored males that sang more vigorously. Sexual selection differed in the extent, strength, and nature on some of the traits between populations. However, the differences in the directionality of selection detected were not a good predictor of population differences. In addition, a character previously shown to be important for species recognition, interpulse interval, was found to be under sexual selection. Our results highlight the complexity of understanding the relationship between within-population sexual selection and population differences. Sexual selection alone cannot predict differences between populations.Peer reviewe
Business Ethics in Third World Countries. A Romanian Representative Case: Rosia Montana
No full textRosia Montana case became representative by its complexity, considering the interaction of the economic with other social sectors on one hand, and on the other hand, considering the context of a economy on the globalization edge in a South-Eastern European country 'rebuilt' after 1989 and in a permanent 'reform' of 20 years, representative by the way the economics dictates to the politics, sealing the road to sustainable disaster in an "era of sustainable developmentâ€. Edifying symbol of the times that we live at the beginning of the XXIst century, maintaing the focus on the Romanian opened wound Rosia Montana is equivalent to a live lesson about the survival or the collapse of the (human) ecosystem. About the morality as a reality of another order than that of biological life and as a sine qua non condition of the humanity preservation.etichs; business.
Running with the Land in Montana
