Abstract:
... For more than 130 years, the type locality of the Plains Spotted Skunk, Spilogale putorius interrupta (Rafinesque, 1820) has been accepted to be along the upper Missouri River. The species' description was based on a specimen observed by Constantine S. Rafinesque during his 1818 exploration of the Ohio River Valley, but Rafinesque never ventured into the animal's geographic range west of the Missi ...
... There are few empirical explanations for consumer preferences for payoff distributions across the agri‐food value chain in terms of psychographic characteristics. In the context of product origin, we contribute to the literature with an incentivized experiment to estimate preferences for payoff distributions among Missouri beef consumers, Missouri beef producers, and non‐Missouri beef producers on ...

Abstract:
... Little research has studied consumer preferences for product characteristics and marketing channels in combination. We survey 938 specialty crop consumers in Missouri to inform preferences for 21 specialty crop products, six attributes (local, organic, GMO-free, pesticide-free, appearance, price), and four marketing channels (direct-from-farm, farmers market, warehouse club, grocery store). We obs ...

Abstract:
... We provide a picture of public attitudes toward desirable land uses and land features (LULFs) for the future of the Upper Missouri River Basin (UMRB) and examine if residents’ desires are correlated with socioenvironmental conditions of their landscapes. We conducted a survey of residents in 22 human population centers (HPCs), generated a ranking of residents’ desired LULFs, and performed a correl ...

Abstract:
... Urban prairie “gardens/plots” are gaining popularity for providing similar ecological services as remnant and restored prairies, which are predominantly found in rural areas. However, it is not known to what extent small urban prairies can sustain the plant-pollinator interactions that are vital to both the insects and the plants. The goal of our research was to examine plant/pollinator interactio ...

Abstract:
... The Pallid Sturgeon (Scaphirhynchus albus) Conservation Propagation and Stocking Program began stocking in the Missouri River above Fort Peck Reservoir in 1998 with 1997‐year‐class pallid sturgeon. Within the 1997‐year class, all hatchery‐origin pallid sturgeon females that reached reproductive maturation by 2016 underwent mass ovarian follicular atresia. Using combined historical and contemporary ...

Abstract:
... Living collections grown in outdoor landscapes within botanic gardens play an increasingly important role in ex situ species conservation, but there is little work predicting the survival of different plant species in these landscapes. Here we present an approach to predict the survival of plants grown from wild propagules in botanic gardens, based on climatic provenance. We developed mixed effect ...

Abstract:
... The North American Waterfowl Management Plan highlights the importance of enhancing waterfowl habitat for productivity and resilience. Many forms of land management are conducted in wetlands to support the diverse communities of waterfowl and other species. Primary burrowing crayfish are also abundant and important in these environments, but little research is available assessing the effects of wa ...

Abstract:
... With the introduction in recent years of high-yield blight-resistant chestnut varieties, the commercial chestnut industry in the United States is expanding. Accompanying this expansion is a resurgence in a primary pest of chestnut: C. sayi, the lesser chestnut weevil. This weevil damages the nut crop and infestations can surge from 0 to close to 100% in as little as two years. Understanding the dy ...

Abstract:
... Melanoplus macclungi Rehn, 1946 is a little-known grasshopper originally recorded from Sun City, Kansas. As part of a survey of Oklahoma grasshoppers, we also collected this species throughout western Oklahoma, and northeast Arkansas. Analysis of citizen science data resulted in additional records for M. macclungi in central Arkansas and southwest Missouri. We have also recorded information on hab ...

Abstract:
... Insectivorous lizards can alter arthropod community structure and composition. Collared lizards (Crotaphytus collaris) are believed to be keystone predators for Ozark glade grasshopper (Orthoptera) communities by increasing species richness on smaller glades. However, the interaction between collared lizard presence and glade area on orthopteran species richness has been inconsistent between studi ...

Abstract:
... Understanding movement and dispersal dynamics of mobile, large‐river fishes is essential to adopting an ecologically relevant spatial scale for research and management. Movement and dispersal patterns of Blue CatfishIctalurus furcatus, a large‐river specialist, have been mostly investigated in large river systems within their native range, with little emphasis on tributaries and the influence of c ...

Abstract:
... Artificial levees are anthropogenic structures designed to hydrologically disconnect rivers from floodplains. The extent of artificial levees in the contiguous United States (CONUS) is unknown. To better estimate the distribution of artificial levees, we tested several different geomorphic, land cover, and spatial variables developed from the National Elevation Dataset, the National Land Cover dat ...

Abstract:
... Rice is typically produced under flooded conditions, but upward of 120,000 ha of furrow‐irrigated rice (FIR) were produced in Arkansas and Missouri in 2020. Nitrogen management will inherently vary under FIR production due to greater N loss potential, especially via nitrification–denitrification stimulated by wetting and drying cycles of the soil. A series of trials were conducted from 2018 to 202 ...

Abstract:
... Small, shallow waterbodies are potentially important sites of greenhouse gas release to the atmosphere. The role of ebullition may be enhanced here relative to larger and deeper systems, due to their shallow water, but these features remain relatively infrequently studied in comparison to larger systems. Herein, we quantify ebullitive release of methane (CH₄) in small shallow ponds in three region ...

Abstract:
... Blue Sucker Cycleptus elongatus is a species of concern across much of its native range due to population fragmentation and habitat loss. A primary component of managing this species is monitoring various population characteristics, including size structure. A common way to quickly index population size structure is to calculate the proportional size distribution (PSD). However, no standard length ...

Abstract:
... Although human fragmentation of freshwater habitats is ubiquitous, the genetic consequences of isolation and a roadmap to address them are poorly documented for most fishes. This is unfortunate, because translocation for genetic rescue could help mitigate problems. We used genetic data (32 SNPs) from 203 populations of westslope cutthroat trout (Oncorhynchus clarkii lewisi) to (1) document the eff ...

Abstract:
... MAIN CONCLUSION: Amplification and overexpression of the target site glutamine synthetase, specifically the plastid-located isoform, confers resistance to glufosinate in Amaranthus palmeri. This mechanism is novel among glufosinate-resistant weeds. Amaranthus palmeri has recently evolved resistance to glufosinate herbicide. Several A. palmeri populations from Missouri and Mississippi, U.S.A. had s ...
... The Big River, in the Old Lead Belt, southeast Missouri, experienced large-scale contamination of channel sediments and floodplain soils from over 200 years of lead mining pollution. Sediments of gravel bars downstream of mining in Big River are contaminated with Pb and Zn and have higher metal concentrations than upstream sites. Plants on these contaminated gravel bars are thus exposed to high me ...

Abstract:
... A circular economy (CE) aims to decouple human activities from economic activities and resource use, and its overall goal is reducing or avoiding negative environmental externalities. The newly developed Circular Economy Lifecycle Assessment and Visualization (CELAVI) framework simulates changes in supply chain environmental impacts as it transitions toward circularity. This study expands CELAVI b ...
