A Satellite-Based Assessment Of The Relative Contribution Of Hydroclimatic Variables On Vegetation Growth In Global Agricultural And Non-Agricultural Regions, Akarsh Asoka, Brian Wardlow, Tsegaye Tadesse, Matthew Huber, Vimal Mishra
A Satellite-Based Assessment Of The Relative Contribution Of Hydroclimatic Variables On Vegetation Growth In Global Agricultural And Non-Agricultural Regions, Akarsh Asoka, Brian Wardlow, Tsegaye Tadesse, Matthew Huber, Vimal Mishra

Vegetation growth plays a crucial role in the carbon cycle and climate change mitigation. However, the relative contribution of hydroclimatic variables (relative humidity, terrestrial water storage, day and night-time land surface temperatures) on vegetation growth of agricultural and nonagricultural areas at the global scale remains unexplored. Using satellite-based datasets, we examined the changes in Normalized Difference Vegetation Index (NDVI) and the four hydroclimatic variables during 2003–2014. Also, the relative contribution of the four hydroclimatic variables on vegetation growth in agricultural and nonagricultural areas was estimated. A significant (p-value < 0.05) greening has occurred in the agricultural regions of India and Brazil during 2003–2014. Whereas in nonagriculture areas, a considerable greening occurred only in India and China during the 2003–2014 period. Among the four hydroclimatic variables, both day-time and night-time land surface temperature are the significant contributors of vegetation growth in the two-thirds of the global landmass. Terrestrial water storage is a substantial contributor to the vegetation growth in the tropics and subtropics. Night-time land surface temperature is strongly associated with the vegetation growth in the colder regions. The hydroclimatic variables do not explain the considerable amount of the total variance of vegetation growth over the agricultural areas in China, which is due to human agricultural management practices. Generally, the response of hydroclimate variables on vegetation growth in the agricultural and nonagricultural areas has significant implications in many areas, including food security, carbon sequestration, water resource management, and climate change.

Boundary Spanning: Its Role In Trust Development Between Stakeholders In Integrated Water Resource Management, Jodi Lynn Delozier, Mark E. Burbach
Boundary Spanning: Its Role In Trust Development Between Stakeholders In Integrated Water Resource Management, Jodi Lynn Delozier, Mark E. Burbach
School of Natural Resources: Faculty Publications
This study sheds light on the importance of boundary spanners in developing the conditions that foster trust between stakeholders in integrated water resource management (IWRM). Boundary spanners routinely reach across organizational borders to build interconnections and interdependencies in order to manage complex problems, inform policy, and encourage knowledge sharing. The importance of the boundary spanning role has been shown in organizational business practices, urban planning, and higher education yet little research exists on its impact in IWRM. The mixed methods approach used in this study involved surveying and interviewing individuals with previous experience with IWRM in Nebraska. The results of …

All 50 states offer preferential property tax programs that lower the taxes paid on enrolled agricultural and/or forest lands. While agroforestry is a land-use that combines elements of both agriculture and forestry, eligibility criteria and other rules and regulations may prevent landowners from enrolling agroforestry practices in one or more of the agricultural and forestry tax programs. This pilot-scale study developed conceptual and methodological frameworks to identify the current barriers to and opportunities in preferential tax policies applicable to agroforestry practices. We conducted an extensive review of state preferential property tax programs relevant for agroforestry practices, following focus group discussions …

A key pursuit in contemporary ecology is to differentiate regime shifts that are truly irreversible from those that are hysteretic. Many ecological regime shifts have been labeled as irreversible without exploring the full range of variability in stabilizing feedbacks that have the potential to drive an ecological regime shift back towards a desirable ecological regime. Removing fire from grasslands can drive a regime shift to juniper woodlands that cannot be reversed using typical fire frequency and intensity thresholds, and has thus been considered irreversible. This study uses a unique, long-term experimental fire landscape co-dominated by grassland and closed-canopy juniper woodland …

Ecosystem functioning and community structure are recognized as key components of ecosystem integrity, but comprehensive, standardized studies of the responses of both structural and functional indicators to different types of anthropogenic pressures remain rare. Consequently, we lack an empirical basis for (i) identifying when monitoring ecosystem structure alone misses important changes in ecosystem functioning, (ii) recommending sets of structural and functional metrics best suited for detecting ecological change driven by different anthropogenic pressures, and (iii) understanding the cumulative effects of multiple, co-occurring stressors on structure and function. We investigated variation in community structure and ecosystem functioning of stream ecosystems along …

School of Natural Resources: Faculty Publications
The Aransas-Wood Buffalo population of Whooping Cranes (Grus americana) migrates approximately 4000 km through the central Great Plains biannually, between their breeding and wintering grounds. Whooping Cranes depend on stopover sites to provide secure resting locations and the caloric resources necessary to complete their migration, such as the USFWS-designated critical habitat area in the Central Platte River Valley (CPRV) of Nebraska. This area includes braided river habitat characterized by low-elevation and submerged sandbars, which provide important roosting and foraging opportunities for migrating Whooping Cranes. We used long-range photography, videography, and behavioral scan sampling to document forage items consumed by Whooping …

Motivations for hunting and fishing extend beyond harvesting game and include social, psychological, emotional, and physical benefits. We used data from a web-based questionnaire to compare relationships between preferred hunting or fishing activity types, state of residence, and motivations of hunters and anglers across the central United States (U.S.). Exploratory factor analysis yielded four motivation factors: nature, social, food, and challenge. Differences in terms of state were negligible across all motivation factors (η2p < .01), indicating similarity across states. Nature (η2p = .01) and social (η2p < .01) factors were the first and …

Quantitative modelling plays an important role as biology increasingly deals with big data sets, relies on modelling to understand system dynamics, makes predictions about impacts of changes, and revises our understanding of system interactions. An assessment of quantitative modelling in biology was administered to students (n = 612) in undergraduate biology courses at two universities to provide a picture of student ability in quantitative reasoning within biology and to determine how capable those students felt about this ability. A Rasch analysis was used to construct linear measures and provide validity evidence for the assessment and to examine item statistics …
