Chelostoma Latreille, 1809 (Hymenoptera: Megachilidae) of Montana, including first records of the introduced bees Chelostoma campanularum (Kirby, 1802) and Chelostoma rapunculi (Lepeletier, 1841)
(Pacific Coast Entomological Society, 2023-05)The megachilid bees of the genus Chelostoma Latreille, 1809 in Montana, U.S.A., are reviewed. Two Palearctic species, Chelostoma (Foveosmia) campanularum (Kirby, 1802) and Chelostoma (Gyrodromella) rapunculi (Lepeletier, ... -
Lentil nitrogen fixation response to fertilizer and inoculant in the northern Great Plains
(Wiley, 2023-08)Lentil (Lens culinaris Medikus) production in the semiarid northern Great Plains of the United States has increased dramatically over the past two decades. Lentil in rotation provides agroecosystem benefits of more efficient ... -
Nitrogen fixation among pea and lentil varieties in the Northern Great Plains
(Wiley, 2023-08)Pulse crops, including lentil (Lens culinaris Medik.) and pea (Pisum sativum L.), can improve the sustainability of Northern Great Plains cropping systems, largely through biological N fixation. Greater N fixation amounts ... -
Retrospective use of integrative taxonomy in classical biological control: The unintentional introduction of the weevil Rhinusa dieckmanni to North America
(Elsevier BV, 2023-08)A seed-feeding weevil introduced to North America (NA) as a biological control agent of the invasive toadflax Linaria dalmatica (L.) Mill., identified then as Gymnetron antirrhini “Dalmatian host race” and subsequently ... -
Pinus contorta Alters Microenvironmental Conditions and Reduces Plant Diversity in Patagonian Ecosystems
(MDPI AG, 2023-02)Pinus contorta is considered one of the most invasive tree species worldwide, generating significant impacts on biodiversity and ecosystems. In several Patagonian ecosystems in southern Chile, it has escaped from plantations ... -
Impact of Puccinia punctiformis on Cirsium arvense performance in a simulated crop sequence
(Frontiers Media SA, 2023-05)Cirsium arvense (Canada thistle) is a perennial weed that causes significant economic losses in agriculture. An extensive rhizomatous root system makes C. arvense difficult to manage, particularly in agricultural systems ... -
Long‐term cover crop effects on biomass, soil nitrate, soil water, and wheat
(Wiley, 2023-05)Cover crops during summer fallow have been rarely researched in the semiarid northern Great Plains. This study was conducted during 2012–2019 at four Montana locations and included four functional groups (Brassica family, ... -
Aerobic methane synthesis and dynamics in a river water environment
(Wiley, 2023-06)Reports of aerobic biogenic methane (CH4) have generated new views about CH4 sources in nature. We examine this phenomenon in the free-flowing Yellowstone river wherein CH4 concentrations were tracked as a function of ... -
Cowpea extrafloral nectar has potential to provide ecosystem services lost in agricultural intensification and support native parasitoids that suppress the wheat stem sawfly
(Oxford Academic, 2023-05)The native parasitoids Bracon cephi (Gahan) and B. lissogaster Muesebeck (Hymenoptera: Braconidae) reduce populations of Cephus cinctus Norton (Hymenoptera: Cephidae), a native grassland species, and major wheat pest on ... -
Using spatially variable nitrogen application and crop responses to evaluate crop nitrogen use efficiency
(Springer Science and Business Media LLC, 2023-05)Low nitrogen use efficiency (NUE) is ubiquitous in agricultural systems, with mounting global scale consequences for both atmospheric aspects of climate and downstream ecosystems. Since NUE-related soil characteristics ... -
Abutilon theophrasti’s Resilience against Allelochemical-Based Weed Management in Sustainable Agriculture – Due to Collection of Highly Advantageous Microorganisms?
(MDPI AG, 2023-02)Abutilon theophrasti Medik. (velvetleaf) is a problematic annual weed in field crops which has invaded many temperate parts of the world. Since the loss of crop yields can be extensive, approaches to manage the weed include ... -
Using Stable Isotopes to Determine Natal Origin and Feeding Habits of the Army Cutworm Moth, Euxoa auxiliaris (Lepidoptera: Noctuidae)
(Oxford University Press, 2023-02)The army cutworm, Euxoa auxiliaris (Grote), is a migratory noctuid that is both an agricultural pest and an important late-season food source for grizzly bears, Ursus arctos horribilis (Linnaeus, Carnivora: Ursidae), within ... -
Postglacial adaptations enabled colonization and quasi-clonal dispersal of ammonia-oxidizing archaea in modern European large lakes
(American Association for the Advancement of Science, 2023-02)Ammonia-oxidizing archaea (AOA) play a key role in the aquatic nitrogen cycle. Their genetic diversity is viewed as the outcome of evolutionary processes that shaped ancestral transition from terrestrial to marine habitats. ... -
Supplemental Material: What is the Best Wetland Assessment Tool? A Discrimination of Overlapping Assessment Approaches
(Montana State University, 2023)Within Southwestern Montana, 18 wetland area sites were chosen and assessed by all six tools currently used by the state of Montana for evaluating ecological health, and by the New LDI criteria. Because the sample is ... -
The Bark-Gnawing Beetles of Montana, USA (Coleoptera: Trogossitidae, Peltidae, and Lophocateridae), Including New Substantial Distributional Records for Tenebroides collaris (Sturm)
(Coleopterists Society, 2022-12)Eight species of Trogossitidae, three of Peltidae, and one of Lophocateridae are reported from Montana. Of these, six represent new state records. Records of Tenebroides collaris (Sturm) represent a substantial new westward ... -
Towards a Low-Cost Comprehensive Process for On-Farm Precision Experimentation and Analysis
(MDPI, 2023-02)Few mechanisms turn field-specific ecological data into management recommendations for crop production with appropriate uncertainty. Precision agriculture is mainly deployed for machine efficiencies and soil-based zonal ... -
Biogeochemical and historical drivers of microbial community composition and structure in sediments from Mercer Subglacial Lake, West Antarctica
(Springer Science and Business Media LLC, 2023-01)Ice streams that flow into Ross Ice Shelf are underlain by water-saturated sediments, a dynamic hydrological system, and subglacial lakes that intermittently discharge water downstream across grounding zones of West Antarctic ... -
Rapid upwards spread of non-native plants in mountains across continents
(Springer Science and Business Media LLC, 2023-01)High-elevation ecosystems are among the few ecosystems worldwide that are not yet heavily invaded by non-native plants. This is expected to change as species expand their range limits upwards to fill their climatic niches ... -
