Guide To Usda Agroforestry Research Funding Opportunities

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

This guide is intended for researchers and academics pursuing funding opportunities for research in agroforestry - the intentonal integration of trees and agriculture. The guide provides an overview of external agroforestry research funding opportunities offered by the United States Department of Agriculture (USDA) agencies.

This publication was created for serveral reasons. Agroforestry is not always clearly identified in announcements about research funding opportunities. In addition, research on agroforestry can require a longer time horizon than research on annual systems, so awareness of multiple funding sources or multi-year funding opportunities can be useful. Last, though USDA offers grants that can support …

Evaluation Of Potential Translocation Sites For An Imperiled Cyprinid, The Hornyhead Chub, Brian T. Hickerson, Annika W. Walters

United States Geological Survey: Staff Publications

Translocation of isolated species into suitable habitats may help to secure vulnerable, geographically limited species. Due to the decline of Wyoming Hornyhead Chub Nocomis biguttatus, conservation actions, such as the translocation of populations within the plausible historical range, are being considered to improve population redundancy and resiliency to disturbance events. Translocation of Wyoming Hornyhead Chub must be rigorously evaluated because a hatchery stock does not exist, so all fish used in translocations will come from the wild population. We present an approach to identify the best available translocation sites prior to translocation efforts taking place. We evaluated fish community composition …

An Adapted Framework For Environmental Sustainability Reporting Using Mobile Technologies, Andre P. Calitz, Jaco F. Zietsman

The African Journal of Information Systems

Corporate governance is the process by which organisations are directed and controlled. King IV is regarded as the cornerstone of corporate governance for businesses and emphasises the importance of sustainability reporting in South Africa. Sustainability reporting guidelines inform organisations how to disclose their most critical affects on the environment, society and the economy. The Global Reporting Initiative (GRI) G4 sustainability reporting framework recommends the Standard Disclosures that all organisations should use to report their sustainability impacts and performance. Sustainability reporting frameworks proposed for the Higher Education sector require reporting principles specific to the needs of Higher Education Institutions (HEIs). The …

Using Art And Story To Explore How Primary School Students In Rural Tanzania Understand Planetary Health: A Qualitative Analysis, Elizabeth Vanwormer, Jesca Mlawa, Elizabeth Komba, Christopher Gustafson, Hilda Mrema, Jenny M. Dauer

School of Natural Resources: Faculty Publications

Background The global planetary health community increasingly recognises the need to prepare students to investigate and address connections between environmental change and human health. As we strive to support education on planetary health themes for students of all ages, understanding students’ concepts of linkages between the health of people and animals, and their shared environments might advance educational approaches. Children living in villages bordering Ruaha National Park in Iringa Region, Tanzania, have direct experience of these connections as they share a water-stressed but biodiverse environment with domestic animals and wildlife. Livelihoods in these villages depend predominantly on crop and livestock …

Macrobenthic Infaunal Communities Associated With Deep‐Sea Hydrocarbon Seeps In The Northern Gulf Of Mexico, Travis W. Washburn, Amanda W. J. Demopoulos, Paul A. Montagna

United States Geological Survey: Staff Publications

There are thousands of seeps in the deep ocean worldwide; however, many questions remain about their contributions to global biodiversity and the surrounding deep‐sea environment. In addition to being globally distributed, seeps provide several benefits to humans such as unique habitats, organisms with novel genes, and carbon regulation. The purpose of this study is to determine whether there are unique seep macrobenthic assemblages, by comparing seep and nonseep environments, different seep habitats, and seeps at different depths and locations. Infaunal community composition, diversity, and abundance were examined between seep and nonseep background environments and among three seep habitats (i.e., microbial …

Mensurative Approach To Examine Potential Interactions Between Age-0 Yellow Perch (Perca Flavescens) And Bluegill (Lepomis Macrochirus), Mark A. Kaemingk, David W. Willis

School of Natural Resources: Faculty Publications

Bluegill (Lepomis macrochirus) andyellow perch (Perca flavescens) populations are often sympatric in the Great Plains region of the U.S.A. and portions of Canada; however, very little attention has been given to potential interactions between these species for available resources, especially during the early life stages. Relationships between age-0 bluegill and yellow perch growth and relative abundance were explored across multiple lakes and years within the Nebraska Sandhill region, USA. In addition, four habitat patch types (open water, Phragmites spp., Typha spp., Scirpus spp.) were sampled for age-0 bluegill and yellow perch, and food habits were examined for each species during …

Organochlorine Chemical Residues In Northern Cardinal (Cardinalis Cardinalis) Eggs From Greater Washington, Dc Usa, Christopher J. Schmitt, Kathy E. Echols, Paul H. Peterman, Carl E. Orazio, K. Christiana Grim, Shirlee Tan, Nora E. Diggs, Peter P. Marra

United States Geological Survey: Staff Publications

Northern Cardinal eggs from six neighborhoods near Washington DC were analyzed for organochlorine pesticides and PCBs. All compounds were detected more frequently and at higher concentrations in more heavily urbanized neighborhoods. DDT (mostly as p,pʹ-DDE) was detected in all neighborhoods. p,pʹ-DDT was typically 0.5‒16 ng/g (ww) in most suburban neighborhoods but was not detected (< 0.1 ng/g) in more rural areas; however, p,pʹ-DDT was 127‒1130 ng/g in eggs from two suburban Maryland nests and comprised 65.7% of total p,pʹ-DDT isomers in the most contaminated sample, indicating recent exposure to un-weathered DDT. Total chlordane (sum of 5 compounds) was 2‒70 ng/g; concentrations were greatest in older suburban neighborhoods. Total PCB (sum of detected congeners) was < 5‒21 ng/g. Congener patterns were similar in all neighborhoods and resembled those typical of weathered mixtures. Results indicate that wildlife remains exposed to low concentrations of legacy contaminants in suburban neighborhoods and that cardinal eggs can be used to monitor local- ized contamination.

Morphological And Histological Description Of Small Metoposaurids From Petrified Forest National Park, Az, Usa And The Taxonomy Of Apachesaurus, Bryan M. Gee, William G. Parker

United States National Park Service: Publications

Metoposaurids are Late Triassic temnospondyls that are abundant components of freshwater deposi- tional settings. Although metoposaurids are represented by hundreds of specimens in collections around the world, the vast majority pertain to large-bodied, relatively mature individuals, and as a result, the early stages of ontogeny are still poorly characterised. Small-bodied metoposaurids from North America have traditionally been assigned to Apachesaurus gregorii, interpreted as a diminutive taxon, but this interpretation has not been rigorously tested. Here we provide a morphological description of two new small-bodied metoposaurid specimens from Petrified Forest National Park, AZ, USA. Both provide various anatomical details that improve …

A Behavioral Analysis Of Households Using Reclaimed Water In Irrigation: Case Of Pinellas County, Florida, Natalie Kuraya-Ziyadeh

USF Tampa Graduate Theses and Dissertations

In order to tend to the world’s dwindling freshwater supplies, sustainable alternative methods need to be integrated in order to keep up with the world’s increasing demand. Reclaimed water (RW) is one of the sustainable methods adopted by some Floridian cities such as Tampa, Tallahassee, and St. Pete that provide an alternative water source for non-potable uses. However, despite this alleviating effect RW has on freshwater supplies, it is crucial to recognize the potential harm it poses on neighboring waterbodies due to the residual contaminants it still contains, including Nitrogen (N) and Phosphorous (P). As such, studying residents’ knowledge and …

Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender

Student Theses 2015-Present

This paper aims to shed light on the dissonance caused by the superimposition of Dominant Human Systems on Natural Systems. I highlight the synthetic nature of Dominant Human Systems as egoic and linguistic phenomenon manufactured by a mere portion of the human population, which renders them inherently oppressive unto peoples and landscapes whose wisdom were barred from the design process. In pursuing a radical pragmatic approach to mending the simultaneous oppression and destruction of the human being and the earth, I highlight the necessity of minimizing entropic chaos caused by excess energy expenditure, an essential feature of systems that aim …

Adult Bobcat (Lynx Rufus) Habitat Selection In A Longleaf Pine Savanna, Andrew R. Little, L. Mike Conner, Michael J. Chamberlain, Nathan P. Nibbelink, Robert J. Warren

School of Natural Resources: Faculty Publications

Background: Pine savannas are primarily managed with frequent prescribed fire (≤ 3 years) to promote diversity of flora and fauna, and to maintain open, park-like conditions needed by species such as the endangered red-cockaded woodpecker (Picoides borealis). However, a knowledge gap exists in our understanding of bobcat (Lynx rufus) habitat selection in longleaf pine savannas and research is warranted to direct our future management decisions.

Methods: We examined bobcat habitat selection in a pine savanna managed with frequent fires at two spatial scales (i.e., study area boundary [hereafter, landscape scale]) and annual area of use [95% …

Testing Methods To Mitigate Caribbean Yellow-Band Disease On Orbicella Faveolata, Carly J. Randall, Elizabeth M. Whitcher, Tessa Code, Clayton Pollock, Ian Lundgren, Zandy Hillis-Starr, Erinn M. Muller

United States National Park Service: Publications

Outbreaks of coral diseases continue to reduce global coral populations. In the Caribbean, yellow band is a severe and wide-spread disease that commonly affects corals of the Orbicella spp. complex, significantly impeding coral reproduction, and hindering the natural recovery of Orbicella spp. populations. Caribbean yellow-band disease (CYBD) lesions may be severe, and often result in the complete loss of coral tissue. The slow spread of CYBD, however, provides an opportunity to test methods to mitigate the disease. Here we report the results of in situ experiments, conducted within Buck Island Reef National Monument in St. Croix, USVI, to test the …

Population Characteristics Of A Closed Northern Pike (Esox Lucius) Catch-And-Release Population In Minnesota, John Kempe

Biology Graduate Theses

Literature regarding catch-and-release populations of Northern Pike are rare and provide a unique perspective on their population dynamics. Shingobee Lake is a 64- ha mesotrophic lake with a maximum depth of 12.2 m located in northern Minnesota. Northern Pike fishing has been catch-and-release only since 2005, and there are no public accesses on the lake. Annual ice-out trap-netting occurred from 2009-2017, and a sizable amount of the Northern Pike recaptured via trapnet or angling had been previously tagged (37-59%). The lack of exploitation and high tagging percentage provided a unique opportunity to study the population dynamics of Northern Pike. Shinogbee’s …

Winter Bat Activity In A Landscape Without Traditional Hibernacula, Amy M. Hammesfahr, Rene E. Ohms

United States National Park Service: Publications

Abstract

Prior to 2014, bat research at Devils Tower National Monument (DETO) focused on bats present during the summer months. Biologists at DETO assumed local bats were strictly summer residents due to the presumed lack of typical habitat features associated with bat hibernation, such as caves and mines. This lack of traditional hibernacula features at DETO discouraged staff and research cooperators from studying winter bat populations. Despite the earlier assumption that bats were unlikely to hibernate on the monument, DETO documented significant winter bat activity through passive winter acoustic monitoring. This study is the first study at DETO that documents …
