(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Neonicotinoids are a class of pesticides that have been prevalently used in agriculture since the 1990s. Globally, most neonicotinoid application ...
Factors influencing practitioner adoption of agroforestry : a USDA SARE case study
(University of Missouri--Columbia, 2020)
Agroforestry practices offer a compelling alternative to conventional agriculture as they provide a broad range of economic, ecological and social benefits. Despite its' recognized potential, on-the-ground adoption of U.S. agroforestry remains...
Agroforestry adoption: influential factors, land manager perceptions, and willingness-to-accept payments
(University of Missouri--Columbia, 2021)
with higher incomes, greater knowledge of agroforestry practices, and positive perceptions of agroforestry's ability to improve soil health were significantly more willing to adopt agroforestry practices, while those with larger farm sizes were less willing...
Heterogeneity in body condition, survival, and seasonal origins among lesser snow and Ross's geese
(University of Missouri--Columbia, 2018)
Individual heterogeneity in fitness within a population is well established and provides the required variability for natural selection to take place. Yet, in the case of overabundant midcontinent lesser snow (Anser ...
The assessment of soil enzyme activities in multiple land use in Central Kalimantan, Indonesia
(University of Missouri--Columbia, 2018)
ecosystems especially comparing agroforestry practices in peat areas with other land use practices on enzyme activities. The objective of this study was to compare soil quality, particularly focused on soil enzyme activities among four land use systems common...

Phytoplankton response to water quality threats in Midwest reservoirs
(University of Missouri--Columbia, 2021)
Harmful cyanobacterial blooms and invasive species threaten water quality. These threats are expected to worsen in the future, emphasizing the need for creative management solutions and a thorough understanding of their ...
Assessing red wolf conservation based on analyses of habitat suitability and human perception of carnivores
(University of Missouri--Columbia, 2018)
The red wolf (Canis rufus) is a critically endangered species endemic to the southeastern United States. Currently the world's only wild population resides in a single locale on the Albemarle Peninsula in northeastern North ...
Assessment of a voluntary nonlead ammunition outreach program on midwestern national wildlife refuges
(University of Missouri--Columbia, 2020)
an outreach program during 2016–2018 encouraging deer hunters to use nonlead ammunition while deer hunting on 54 National Wildlife Refuges (NWRs). This project used a mixed methods approach incorporating 12 structured observations of presentations given...
Educating for adoption : understanding long-term outcomes of the Agroforestry Academy
(University of Missouri--Columbia, 2020)
Agroforestry adoption remains low in temperate regions despite academic acceptance of diverse benefits. And while education is often cited as a tool for empowering adoption, researchers have struggled to identify generalizable ...
