Lessons from the literature and stakeholder interviews on the aims and purpose for stakeholder engagement
Main Speaker: Weston M. Eaton
Assistant Research Professor, Department of Agricultural Economics, Sociology, and Education; The Pennsylvania State University
Date: 10/2/2019
Time: 3:30 PM
Location: 107 South Hardin Hall (Auditorium)
Abstract
Complex environmental challenges including nonpoint source pollution and groundwater contamination cannot be solved by single entities but require collaboration across the diverse stakeholders who affect and are affected by these problems. Stakeholder engagement is increasingly utilized by agencies and others on local to federal scales to address such complex challenges. However, while the practice of stakeholder engagement is increasingly common, scholars tell us evidence for whether and how engagement can lead to positive social and environmental change remains in dispute. This presentation addresses this puzzle in three parts. First, I highlight factors and concepts the literature tells us are key to understanding whether and how stakeholder engagement can lead to positive change in people and the environment. Second, I report findings from interviews where water resource stakeholders in Pennsylvania and Nebraska were asked to describe what they saw as the purpose for broadening stakeholder participation in water resource decision-making. And third, I describe an ongoing research and engagement project in Nebraska, Pennsylvania, and Arizona, where practitioners and researchers are simultaneously bringing together and facilitating engagement across diverse stakeholders while studying what changes with people and the environment through this process.Tracking Drought Here and Abroad: Tools of the Trade
Main Speaker: Brian Wardlow
Other Speakers: Mark Svoboda
Date: 10/9/2019
Time: 3:30 PM
Location: 107 South Hardin Hall (Auditorium)
Abstract
Countries around the globe are increasingly vulnerable to extreme climate events, including drought, and the disruption they cause. The forecast is for increasing risk to drought over the next 20 years with substantial environmental and societal impacts on issues centered on water, food, energy and national security. Drought is a wicked natural hazard with its reach extending beyond the threat of crop losses and severe wildfires into the creation of unstable “hot spots” of societal unrest and conflict around the globe. Synergies between the globe.
Synergies between the National Drought Mitigation Center (NDMC) and Center for Advanced Land Management Information Technologies (CALMIT) in the School of Natural Resources and other researchers at the University of Nebraska as well as with several federal and international agencies has led the development of flexible, scalable drought monitoring and early warning systems in the United States and countries throughout the world.
The presentation will discuss the complex face of drought and the historical development of operational drought monitoring and early warning systems that integrate key environmental conditions (precipitation, soil moisture, vegetation health and evapotranspiration) observed from satellite remote sensing and other spatial information (soils and land use/land cover type) for tailored combined drought indicators (CDIs). Such indicators will include the U.S. Drought Monitor (USDM), Vegetation Drought Response Index (VegDRI), Quick Drought Response Index (QuickDRI) and other CDIs developed for regions such as the Middle East/North Africa and southern Africa. Collectively, this work builds upon the extensive expertise in drought at the NDMC and satellite remote sensing of CALMIT to advance the state-of-art monitoring and early warning approaches for the global drought community.

Nature’s fat burning machine: brown adipose tissue in a hibernating mammal
Main Speaker: Matthew T. Andrews
Director, Nebraska EPSCoR
Date: 10/16/2019
Time: 3:30 PM
Location: 107 South Hardin Hall (Auditorium)
Abstract
Brown adipose tissue, commonly known as “brown fat,” is a unique thermogenic tissue in mammals that rapidly produces heat via nonshivering thermogenesis. Small mammalian hibernators have evolved the greatest capacity for brown adipose tissue (BAT) as they use it torewarm from hypothermic torpor numerous times throughout the hibernation season. Investigations into hibernator BAT physiology have been occurring for decades, however recent efforts have been directed towards understanding the molecular underpinnings ofBAT regulation and function using a variety of methods, from mitochondrial functional assays to “omics” approaches. As a result, the inner-workings of hibernator BAT are now being illuminated. In this seminar I will discuss recent research progress that has identified players and pathways involved in brown adipocyte differentiation and maturation, as well as those involved in metabolic regulation. The unique phenotype of hibernation, and its reliance on BAT to generate heat to arouse from torpor, has uncovered new molecular mechanisms and potential strategies for biomedical applications.Speaker's Bio

Main Speaker: Andrea Basche
Assistant Professor in Cropping Systems, Department of Agronomy and Horticulture, UNL
Date: 10/23/2019
Time: 3:30 PM
Location: 107 South Hardin Hall (Auditorium)
Abstract
In spite of tremendous increases in crop productivity over the last number of decades, there are currently a number of economic, climate, and agronomic challenges facing producers and our environment. It is estimated that net farm income has declined by more than half since 2013, and reports of farm bankruptcies, commodity price fluctuations and trade uncertainty are widespread. Increasing rainfall variability –heavier rain events and longer periods without rain –can degrade soil and water quality while presenting difficult planting and harvest conditions. Herbicide resistant weeds grow more prevalent across the United States, reducing the efficacy of chemically based pest management approaches.
Increasing diversity in cropping systems can address a number of these challenges. Cropping systems represent the combination of the crops, soils, climate, management, people and social systems utilized to cultivate the land.This presentation will include an overview of several projects underway in our research group to optimize and diversify cropping systems in Nebraska. These projects include expanding our understanding of soil health management systems, integrating cover crops into corn-soybean crop rotations, identifying more productive and profitable regions of farms, and educating the next generation of leaders in the state and beyond about the interconnected components of these challenges.

Main Speaker: Stephen Webb
Range and Wildlife Scientist, Noble Research Institute, Ardmore, Oklahoma
Date: 11/6/2019
Time: 3:30 PM
Location: 107 South Hardin Hall (Auditorium)
Abstract
Resource selection modeling has strong applications in conservation because resource selection is a fundamental ecological process shaping movement and distribution, and offers spatially explicit guidance for targeted management. As animals move across the landscape, they must make trade-offs associated with resource selection to meet needs of survival and reproduction, and for minimizing risk. Fitness is influenced by resource-related decisions by individuals where each resource choice has costs and benefits associated with it. Therefore, individual variation (also referred to as heterogeneity) warrants further investigation in resource selection modeling and how it structures demographic performance such as survival. Studies of Rocky Mountain elk (Cervus elaphus) and greater sage-grouse (Centrocercus urophasianus) will be presented to highlight the conceptual framework to study individual variation in resource selection and its applications for modeling demographic outcomes and functional responses, and improving conservation and management. Further examples of hierarchical resource selection and movement models will be highlighted for wild pigs (Sus scrofa), and white-tailed deer (Odocoileus virginianus). The general approach included estimating resource selection functions (RSFs) and estimating Cox proportional hazards models to quantify risk of mortality as a function of covariates depicting landscape-level features. Spatial models of occurrence and risk are combined to provide a spatially-explicit assessment of the relationship between habitat and demographic performance, wherein low-performance habitat (e.g., sink habitat) was defined as high probability of occurrence coupled with high risk of mortality, and high-performance habitat (e.g., source habitat) was high probability of occurrence coupled with low risk of mortality. Prioritizing management based on occurrence without a connection to a demographic outcome risks poor performance because occurrence alone can be a misleading indicator of fitness. Therefore, management may be most effective when individual variation is considered and linked to demographic outcomes.Speaker's Bio

Abstract
Knowledge of ecological condition, patterns and processes is essential for effective conservation and management of fish and rivers. But this knowledge is rarely, if ever, acquired satisfactorily. Sometimes this is because of logistical difficulties (e.g. trying to sample at appropriate temporal and spatial scales), and at other times it is because of a number of assumptions or compromises we make. For example, (a) most ecological studies are carried out over periods far too short to get a good understanding of the dynamics of communities, assemblages, species, populations or even individuals, yet we persist in doing them; (b) the current environment has a legacy of historic disturbances, some of which may not be obvious or have disappeared; (c) we are often unwittingly seduced into thinking that the environmental conditions which prevailed when we were young or at the start of our careers are some kind of baseline towards which we should be heading; and (d) the past is all we have to predict the future. An investigation ofhistorical ecology can open up new opportunities, approaches and understanding for conservation and management. This seminar will make the case for why historical ecology can be useful and why without it we can be swimming in the dark, using examples fromrivers from around the world. I will describe research underway in Murray-Darling Basin rivers that uses historical approaches to shed light on contemporary issues in river conservation and management.Speaker's Bio
