Department of Agronomy and Horticulture: Faculty Publications

Despite the potential to increase soil organic matter, cycle soil nutrients, and suppress weeds, there is a concern that cover crops (CCs) soil water use negatively impacts subsequent crops in water-limited environments. Cover crop management practices such as planting and termination timing may mitigate the detrimental impacts of CCs in semi-arid cropping systems. To determine the effects of CCs under water-limited environments, we evaluated the total CC biomass produced in the fall and spring, soil water content during the subsequent maize growing season, weed density and biomass, crop residue, and soil nutrients at the maize V6 development stage, and maize …

Smart Irrigation System Is One Of The Modern Applied Agricultural Geography Tools., Aintizar \'Iibrahim Almusawii, Aqeel Hassan Yasser Al-Najm

Uruk Journal of Human Sciences

Many studies indicate that geography is applied if its content or content includes an applied research project in any of its natural and human fields, especially the latter because its field is broad and more prejudicial to man, his community and his environment. Therefore, it was necessary to take the concept of sustainable environmental development into consideration because it is one of the interests of applied scientific geography that searches for human interest and benefit in the present and future. The topic of the research is one of the modern topics that pave the way towards sustainable development and its …

Efficacy Of Predator Exclusion Methods And Id Of Nest Predators For Interior Least Terns And Piping Plovers At Off-Channel Nesting Sites Along The Central Platte River, Nebraska, Usa, Kaley Keldsen

Biology Theses, Dissertations, and Student Creative Activity

Nest predation is a major cause of failed shorebird reproduction. Management to increase reproductive success and survival of nesting interior least terns (Sterna antillarum athalassos; hereafter, least tern), and piping plovers (Charadrius melodus) that nest along the Central Platte River focuses on constructing and managing off-channel nesting habitats that are protected and monitored for least tern and piping plover productivity (i.e., nesting success and fledging success). However, nest and brood fates of unknown outcome, failed to unknown causes, or failed due to predation have been high for both species. These uncertainties lead to the investigation of avian and mammalian predator …

Understanding Conflicts In Natural Resources Management: Using Systems Thinking And Systems Dynamics To Model The Relationship Between The American Prairie Reserve And Neighboring Communities, Amanda Hartman Medaries

Biology Theses, Dissertations, and Student Creative Activity

Conservation conflict, whether human-wildlife or human-human, and specifically those that include the public as stakeholders, is seen as one of the most influential reasons reintroduction and/or conservation of species or landscapes is difficult to accomplish. This is due to the numerous mental models involved within conflict. In order to help mitigate or mediate said conflict, understanding these mental models and the roles they play within the system is crucial. Unfortunately, adaptive management, which is reactionary, additive, and most often used within these systems, is unable to do so and solutions to the conflict remain elusive. The aim of this study …


A Systems Approach To Understanding Piping Plover Production On Off-Channel Sandpits Along The Central Platte River, Taylor Morgan Cassidy Sep 2021

A Systems Approach To Understanding Piping Plover Production On Off-Channel Sandpits Along The Central Platte River, Taylor Morgan Cassidy

Biology Theses, Dissertations, and Student Creative Activity

Anthropogenic changes in land use, exploitation of natural resources, climate change, and habitat loss create difficulties managing and conserving species of concern. Managers are often forced to make decisions with incomplete information and much uncertainty. Unsuccessful attempts to manage for and conserve species in the past, may have resulted from failures to recognize the complexity of systems, resulting in actions that may have had unintended consequences. Thus, applying Systems Thinking and System Dynamics is appropriate for understanding what factors influence species success and evaluating what management actions may be implemented to help achieve conservation targets while minimizing negative impacts to …

Contributions Of Individual Cover Crop Species To Rainfed Maize Production In Semi-Arid Cropping Systems, Alexandre T. Rosa, Cody Creech, Roger W. Elmore, Daran Rudnick, John L. Lindquist, Liberty Butts, Italo K. Pinho De Faria, Rodrigo Werle

Department of Agronomy and Horticulture: Faculty Publications

Cover crop (CC) species selection can contribute to reducing soil penetration resistance (brassica species), improved soil nitrogen (N) cycling (legume species), and suppression of weeds (grass species). However, one of the main concerns about including CCs in water-limited environments is soil water use and the consequences to subsequent crops. To determine the effects of individual CC species under water-limited environments, we evaluated fall and spring CC biomass produced, and soil water and N content, penetration resistance, weed density and biomass during the maize growing season, and maize grain yield. The experiment was conducted under a winter wheat-maize-fallow rotation at two …

Faculty, Staff and Student Publications

The etiology of cleft lip with/without cleft palate (CL/P), one of the most frequent craniofacial birth defects worldwide, is complicated by contributions of both genetic and environmental factors. Understanding the etiology of these conditions is essential for developing preventive strategies. This study thus aims to identify regulatory networks of microRNAs (miRNAs), transcriptional factors (TFs) and non-TF genes associated with cleft lip (CL) that are conserved in humans and mice. Notably, we found that miR-27b, miR-133b, miR-205, miR-376b and miR-376c were involved in the regulation of CL-associated gene expression in both humans and mice. Among the candidate miRNAs, the overexpression of …

Ecophysiology Of Grasslands: Dynamic Aspects Of Forage Plant Populations In Grazed Swards, G. Lemaire Sep 2021

Ecophysiology Of Grasslands: Dynamic Aspects Of Forage Plant Populations In Grazed Swards, G. Lemaire

IGC Proceedings (1977-2023)

The aim of this paper is to review knowledge of the ecophysiological mechanisms influencing the dynamics of plant populations in grazed swards. Such an objective requires some definitions. Firstly, it is necessary to define “ecophysiology” as the study of the interactions between biological individuals (plants) with their own environment: how individuals perceive and react to any constraint and change of their environment, and how the functioning of plants as a population can modify their own environment. Such a definition implies a dynamic approach to pant population functioning as resulting from constant plant-plant interactions mediated by micro-environment modifications. In a grazed …

Differential Evolution Algorithm For Ship Path Planning In Open Waters, Yu-Tao Kang, Wei-Jiong Chen, Jin-Hui Wang

Journal of Marine Science and Technology–Taiwan

A general approach to the derivation of simple yet accurate formulas for identifying bandpass nonlinear channels in or-thogonal frequency-division multiplexing (OFDM) systems is proposed in this paper. The OFDM is an widely adopted tech-nique for wideband communication applications. An OFDM signal could be highly vulnerable to nonlinearities in a com-munication link. This makes proper estimation of the nonlin-ear channel essential for an OFDM system. A nonlinear bandpass communication channel is commonly described by a complex Voletrra series, in which the task of nonlinear channel identification is to determine the Volterra kernels. This task can become very difficult when the order …
