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 ... -
Dietary sugars and amino acids increase longevity and enhance reproductive parameters of Bracon cephi and B. lissogaster , two parasitoids that specialise on wheat stem sawfly
(Wiley, 2023)The wheat stem sawfly, Cephus cinctus Norton (Hymenoptera: Cephidae), is a major pest of wheat grown on the Northern Great Plains and Canadian Prairies of North America, causing economic losses of as much as $350 million ... -
Functional genomics analysis identifies loss of HNF1B function as a cause of Mayer–Rokitansky–Küster–Hauser syndrome
(Oxford University Press, 25-10)Mayer–Rokitansky–Küster–Hauser (MRKH) syndrome is a congenital condition characterized by aplasia or hypoplasia of the uterus and vagina in women with a 46,XX karyotype. This condition can occur as type I when isolated or ... -
Antecedent climatic conditions spanning several years influence multiple land-surface phenology events in semi-arid environments
(Frontiers Media SA, 2022-10)Ecological processes are complex, often exhibiting non-linear, interactive, or hierarchical relationships. Furthermore, models identifying drivers of phenology are constrained by uncertainty regarding predictors, interactions ... -
Climate mitigation potential and soil microbial response of cyanobacteria‐fertilized bioenergy crops in a cool semi‐arid cropland
(Wiley, 2022-10)Bioenergy carbon capture and storage (BECCS) systems can serve as decarbonization pathways for climate mitigation. Perennial grasses are a promising second-generation lignocellulosic bioenergy feedstock for BECCS expansion, ... -
Replacing fallow with field pea in wheat production systems across western Nebraska
(Wiley, 2022-11)Integration of field pea (Pisum sativum L.) (FP) into dryland cropping systems has increased due to ecological and economic benefits, paired with a growing market for pea-derived products. Challenges exist in the High ... -
Global distribution and climate sensitivity of the tropical montane forest nitrogen cycle
(Springer Nature, 2022-11)Tropical forests are pivotal to global climate and biogeochemical cycles, yet the geographic distribution of nutrient limitation to plants and microbes across the biome is unresolved. One long-standing generalization is ... -
Weed Communities in Winter Wheat: Responses to Cropping Systems under Different Climatic Conditions
(MDPI, 2022-06)Understanding the impact of biological and environmental stressors on cropping systems is essential to secure the long-term sustainability of agricultural production in the face of unprecedented climatic conditions. This ... -
Sulfur cycling and host-virus interactions in Aquificales-dominated biofilms from Yellowstone’s hottest ecosystems
(Springer Nature, 2021-10)Modern linkages among magmatic, geochemical, and geobiological processes provide clues about the importance of thermophiles in the origin of biogeochemical cycles. The aim of this study was to identify the primary ... -
Predicted climate conditions and cover crop composition modify weed communities in semiarid agroecosystems
(Wiley, 2021-10)The US Northern Great Plains is one of the largest expanses of small grain agriculture, but excessive reliance on off-farms inputs and predicted warmer and drier conditions hinder its agricultural sustainability. In this ... -
Variation in reproductive mode across the latitudinal range of invasive Russian knapweed
(Oxford University Press, 2022-07)For invading species, reproduction is a critical determinant of population establishment as well as spread into new areas. When species have multiple modes of reproduction, the prevalence of different modes can influence ... -
The effects of intraspecific hybridization on the host specificity of a weed biocontrol agent
(Elsevier BV, 2021-06)Hybridization can alter the host-specificity and fitness of herbivorous insects when the hybridizing populations are adapted to different hosts. It is less clear what the effects of admixture may be when genetically distinct ... -
Eriophyid Mites in Classical Biological Control of Weeds: Progress and Challenges
(MDPI AG, 2021-06)A classical biological control agent is an exotic host-specific natural enemy, which is intentionally introduced to obtain long-term control of an alien invasive species. Among the arthropods considered for this role, ... -
Sustained stoichiometric imbalance and its ecological consequences in a large oligotrophic lake
(Proceedings of the National Academy of Sciences, 2022-07)Considerable attention is given to absolute nutrient levels in lakes, rivers, and oceans, but less is paid to their relative concentrations, their nitrogen:phosphorus (N:P) stoichiometry, and the consequences of imbalanced ... -
Cropping systems alter plant volatile emissions in the field through soil legacy effects
(Cambridge University Press, 2022-06)Crops emit a variety of volatile organic compounds (VOCs) that serve as attractants or repellents for pests and their natural enemies. Crop rotations, off-farm chemical inputs, and mechanical and cultural tactics – ... -
Climate change and more disturbed land-use types will further the invasion of a non-native annual grass, Ventenata dubia
(Springer Science and Business Media LLC, 2022-09)Identification of suitable habitat for invasive weeds and their projected infestation extent across different land use cover types under a changing climate is crucial for the broad management goals of prevention, detection, ...
