Sustainable Grazing On Saline Land In Western Australia - Multidisciplinary Research Linking Producers And Scientists, Hayley C. Norman, D. G. Masters, M. G. Wilmot, A. J. Rintoul, R. Silberstein, E. Lefroy, T. York

IGC Proceedings (1977-2023)

Dryland salinity is one of the most critical environmental issues challenging Western Australian farmers. Currently 10% of the cropping zone (1.8 million ha) is salt-affected and this is predicted to increase dramatically in the next 50 years (NLWRA, 2001). Animals grazing saline pasture systems represent the most likely large-scale opportunity for economic return from saline land in the short to medium term. To date, few farmers have invested in large-scale revegetation of saline land as the economic return from grazing has not been perceived to cover costs. Furthermore other benefits of saltland pasture systems, such as biodiversity, water use and …

Low Input Techniques For Firebreak Covering: Agronomic Aspects, S. Caredda, Antonello Franca, F. Sanna, G. Seddaiu

IGC Proceedings (1977-2023)

In Sardinia, wild fire prevention is traditionally "passive" , based on mechanical removal of vegetation and upper soil layers. This has a dramatic negative effect on plant diversity and soil erosion. This experiment concerns "active" prevention of wildfires, based on green covering and grazing of firebreaks. The objective was the establishment of a persistent green cover, to be grazed by animals to reduce fuel accumulation.

Evolution And Ageing Of Brachiaria Brizantha Pasture Component In A Silvopastoral System, M. Rakocevic, F. C. De Oliveira, J. Ribaski, O. J. Lavoranti

IGC Proceedings (1977-2023)

The main causes of the decline of Brachiaria pasture in the tropics are lack of maintenance, fertilisation and excessively high animal stocking rates (Boddey et al., 2004). Brachiaria brizantha has two predominant morphological forms: 1) relatively high stems with grouped tillers at a high position constructed from short leaves (bunch type); 2) low stems with long leaves, which in time evolve into the first type (Kanno et al., 1999). The concept of Brachiaria management involves animals entering to commence grazing when the pasture is 50-60cm high and being removed at 25-30cm, leaving a regrowth period of at least …

The Influence Of Tree Thinning And Tree Species On The Dry Matter Yield Of Grasses Of A Bush Encroached Semi-Arid Savanna In South Africa, G. N. Smit

IGC Proceedings (1977-2023)

The Acacia erubescens-Combetum apiculatum dominated savanna of South Africa is water-limited and an increase in woody plant abundance suppresses the grasses. This is the major reason why thinning or total clearing of all woody plants is often considered by landowners. The objectives of this study were to investigate the influence of intensity of tree thinning and tree species on grass yields in a semi-arid South African savanna.

Productivity Of A Leucaena Leucocephala-Cynodon Nlemfuensis Silvopastoral System With Sheep In Yucatan, Mexico, J. G. Escobedo-Mex, L. Ramirez-Aviles

IGC Proceedings (1977-2023)

Animal production in the tropics of Mexico is based on grazed grasslands of low productivity; this type of production system has reduced the areas of natural vegetation and damaged the ecology (erosion of flora, fauna and soil). Silvopastoral technologies may improve the welfare and economic conditions of the rural population and, consequently, preserve their natural resources. The current work was designed to assess the introduction of Leucaena leucocephala in a silvopastoral system with Cynodon nlemfuensis (star grass) grazed by sheep.

Agroforestry Systems In Cuba: Some Aspects Of Animal Production, J. Iglesias, L. Simón, L. Lamela, I. Hernández, M. Milera, T. Sánchez

IGC Proceedings (1977-2023)

The silvopastoral systems, that nowadays constitute scientific achievements of the Grasses and Forages Research Station "Indio Hatuey ", have been developed from the results of investigations that were carried out since the 1980s, to improve the productivity of natural pastures through the introduction of valuable herbaceous species and tree legumes. Those investigations also determined the essential elements of pasture management such as the optimal stocking rates for low input systems and suitable methods of grazing to obtain sustainability of grasslands.

Optimising Forage Production On Degraded Lands In The Dry Tropics Through Silvopastoral Systems, P. S. Pathak

IGC Proceedings (1977-2023)

In India, 187 M ha out of a total area of 328 M ha face the problem of land degradation, mostly due to water and wind erosion. The problems are aggravated by poor land cover and increasing pressure of human and livestock populations. There is over-exploitation of the scarce resources of forage and firewood. Several techniques, including watershed based silvopastoral land use have been proposed (Patil & Pathak, 1977). Tree, grass and legume based systems have been tried after land treatment to reduce runoff and soil loss while meeting the forage needs of the livestock and firewood for cooking in …

Functional Connectivity Varies Across Scales In A Fragmented Landscape, Kate I. T. Bird, Daniel R. Uden, Craig R. Allen

School of Natural Resources: Faculty Publications

Species of different sizes interact with the landscape differently because ecological structure varies with scale, as do species movement capabilities and habitat requirements. As such, landscape connectivity is dependent upon the scale at which an animal interacts with its environment. Analyses of landscape connectivity must incorporate ecologically relevant scales to address scale-specific differences. Many evaluations of landscape connectivity utilize incrementally increasing buffer distances or other arbitrary spatial delineations as scales of analysis. Instead, we used a mammalian body mass discontinuity analysis to objectively identify scales in the Central Platte River Valley (CPRV) of Nebraska, U.S.A. We implemented a graph-theoretic network …

Sex Differences In Metabolic Phenotype And Hypothalamic Inflammation In The 3xtg-Ad Mouse Model Of Alzheimer's Disease., Lisa S. Robison, Olivia J. Gannon, Abigail E. Salinero, Charly Abi-Ghanem, Richard D. Kelly, David A. Riccio, Febronia M. Mansour, Kristen L. Zuloaga

Faculty Articles

BACKGROUND: Alzheimer's disease (AD) is notably associated with cognitive decline resulting from impaired function of hippocampal and cortical areas; however, several other domains and corresponding brain regions are affected. One such brain region is the hypothalamus, shown to atrophy and develop amyloid and tau pathology in AD patients. The hypothalamus controls several functions necessary for survival, including energy and glucose homeostasis. Changes in appetite and body weight are common in AD, often seen several years prior to the onset of cognitive symptoms. Therefore, altered metabolic processes may serve as a biomarker for AD, as well as a target for treatment, …

An Allelic Series Of Spontaneous Rorb Mutant Mice Exhibit A Gait Phenotype, Changes In Retina Morphology And Behavior, And Gene Expression Signatures Associated With The Unfolded Protein Response., George Murray, Jason A. Bubier, Oraya Zinder, Belinda S. Harris, James Clark, Mia-Cara Christopher, Courtany Hanley, Harianto Tjong, Meihong Li, Chew Yee Ngan, Laura G Reinholdt, Robert W. Burgess, Abigail L D Tadenev

Faculty Research 2023

The Retinoid-related orphan receptor beta (RORβ) gene encodes a developmental transcription factor and has 2 predominant isoforms created through alternative first exon usage; one specific to the retina and another present more broadly in the central nervous system, particularly regions involved in sensory processing. RORβ belongs to the nuclear receptor family and plays important roles in cell fate specification in the retina and cortical layer formation. In mice, loss of RORβ causes disorganized retina layers, postnatal degeneration, and production of immature cone photoreceptors. Hyperflexion or "high-stepping" of rear limbs caused by reduced presynaptic inhibition by Rorb-expressing inhibitory interneurons of the …

Rho Enhancers Play Unexpectedly Minor Roles In Rhodopsin Transcription And Rod Cell Integrity, Chi Sun, Philip A Ruzycki, Shiming Chen

2020-Current year OA Pubs

Enhancers function with a basal promoter to control the transcription of target genes. Enhancer regulatory activity is often studied using reporter-based transgene assays. However, unmatched results have been reported when selected enhancers are silenced in situ. In this study, using genomic deletion analysis in mice, we investigated the roles of two previously identified enhancers and the promoter of the Rho gene that codes for the visual pigment rhodopsin. The Rho gene is robustly expressed by rod photoreceptors of the retina, and essential for the subcellular structure and visual function of rod photoreceptors. Mutations in RHO cause severe vision loss in …

Examining The Restoration Potential Of Prescribed Fire And Tree Girdling Treatments On A Fire Dependent Ecosystem: Ecosystem Responses And Management Implications, Rebecca Daigle

Masters Theses

Oak savannas have greatly declined since the 1800s and management is needed to maintain these rare community types. A combination of prescribed burns and mechanical thinning are a common practice to increase forb abundance and biodiversity. This study examines the viability of another technique to thin the canopy called girdling, which was used in conjunction with low-intensity prescribed burns. Early summer prescribed burns were conducted in 2017, 2019, and 2021, while girdling treatments were implemented in 2017 and 2019. The study was conducted in Kent County, Michigan at two degraded former oak savanna communities. In 2022, we collected data to …

Cytokine Profiles In Peruvian Pinnipeds And Their Relationships With Environmental Stressors, Mykenzee L. Munaco

All HCAS Student Capstones, Theses, and Dissertations

Large colonies of two vulnerable, sympatric pinniped species, Peruvian fur seals (Arctocephalus australis Peruvian subpopulation; PFS) and South American sea lions (Otaria byronia; SASL), reside and reproduce in Punta San Juan, Peru (PSJ) where they are exposed to stressors such as environmental contaminants and El Niño-Southern Oscillation (ENSO) events. Cytokine concentrations can be indicative of an animal’s health and immune function by allowing for immunoresponse characterization as Th1 or Th2 dominant. Utilizing an archived pinniped plasma collection of samples from 2009-2019 (n=148), 13 cytokines were analyzed in PFS and SASL: GM-CSF, IFN-γ, KC-like, MCP-1, TNF-α, IL-2, IL-6, …

Evaluating Post-Release Survival And Distribution Of Juvenile Swordfish (Xiphias Gladius) Caught On Buoy Gear Within The Gulf Of Mexico And The Florida Straits, Cody Rewis

All HCAS Student Capstones, Theses, and Dissertations

Buoy gear used to target swordfish (Xiphias gladius) has become an increasingly popular commercial gear type throughout the United States fisheries in both the Atlantic and Pacific oceans. Buoy gear can be defined as a series of independent free-floating gear where each rig consists of at least one floatation device, a vertical mainline, and no more than two hooks. Because of the potential modifications to the component parts and deployment strategies, buoy gear has been hypothesized to decrease bycatch interaction and dead discard numbers by targeting specific depths of swordfish habitat throughout various times of the day. Under the Deepwater …
