Effects Of Nitrogen On The Growth Of Hyparrhenia Diplandra, J Nkandza Apr 2024

Effects Of Nitrogen On The Growth Of Hyparrhenia Diplandra, J Nkandza

IGC Proceedings (1997-2023)

The nitrogen effects on Hyparrhenia diplandra were studied. Plants were grown on nutrient solutions of variable concentrations in nitrogen. The supplied nitrogen increased tillering, leaf production, lamina area, total dry matter accumulation and total nitrogen accumulation in lamina. A detailed examination showed that the effect on tillering was the main cause of the differences observed in dry weights between different treatments. The nitrogen supply elongated significantly the lamina and nitrogen deficiency increased its thickness; but this was not enough to compensate the loss of weight in lower nitrogen treatment. The lamina area as well as nitrogen accumulation in the lamina …

Partitioning Of Phosphorus In White Clover Populations With Different Nodulation Patterns, J R. Crush Apr 2024

Partitioning Of Phosphorus In White Clover Populations With Different Nodulation Patterns, J R. Crush

IGC Proceedings (1997-2023)

The objective of this study was to see if a white clover (Trifolium repens L.) population selected for development of relatively few, but large nodules, differed in the way it used absorbed phosphorus, compared to a white clover population selected for many small nodules. Plants of both populations were grown in minus-nitrogen sand culture and the dry weights and phosphorus contents of shoots, roots and nodules were measured. There were no differences in growth or partitioning of dry matter or phosphorus between the clover lines.

Paternal Programming: The Role Of Seminal Plasma In Pregnancy Hemodynamics And Offspring Growth, Rebecca Michele Swanson Dec 2023

Paternal Programming: The Role Of Seminal Plasma In Pregnancy Hemodynamics And Offspring Growth, Rebecca Michele Swanson

Theses and Dissertations

Seminal plasma is commonly known to serve as a transport medium for sperm as it moves through the female reproductive tract for fertilization, however, more recent evidence demonstrates seminal plasma induces an expansive inflammatory response in the uterus. Murine models have found this inflammatory response is important for clearing pathogens and poor-quality sperm, eliciting the secretion of cytokines, chemokines, and embryokines that aid in embryo attachment and growth, placental angiogenesis, and blunting maternal immunity to the embryo. However, there is minimal research on the impacts of seminal plasma uterine priming in bovine, and more specifically embryo growth, uterine blood flow, …

Osmoregulation And Appetite Regulation In A Basal Vertebrate, The Sea Lamprey (Petromyzon Marinus), Jessica Norstog

Doctoral Dissertations

Lamprey (Petromyontiformes) are the oldest extant family in the vertebrate lineage, providing a unique phylogenetic position for studies on vertebrate evolution. As a basal vertebrate, sea lamprey (Petromyzon marinus) is an important species to understand evolution and comparative physiological mechanisms, including osmoregulation and appetite regulation. Sea lamprey has anadromous (native to the Atlantic Ocean) and landlocked (invasive in the Laurentian Great Lakes in North America) populations. In both populations of sea lamprey, the blind filter-feeding freshwater (FW) larvae burrow in stream sediments for until undergoing a hormonal-driven metamorphosis. During this phase, sea lamprey do not feed as major …

Saturating Growth Rate Against Phosphorus Concentration Explained By Macromolecular Allocation, Gabrielle Armin, Jongsun Kim, Keisuke Inomura Aug 2023

Saturating Growth Rate Against Phosphorus Concentration Explained By Macromolecular Allocation, Gabrielle Armin, Jongsun Kim, Keisuke Inomura

School of Earth, Environmental, and Marine Sciences Faculty Publications and Presentations

The saturating relationship between phytoplankton growth rate and environmental nutrient concentration has been widely observed, yet the mechanisms behind the relationship remain elusive. Here, we use a mechanistic model of phytoplankton and show that the saturating relationship between growth rate and phosphorous concentration can be interpreted by intracellular macromolecular allocation. At low nutrient levels, the diffusive nutrient transport linearly increases with the phosphorous concentration, while the internal phosphorous requirement increases with the growth rate, leading to a non-linear increase in the growth rate with phosphorous. This increased phosphorous requirement is due to the increased allocation to biosynthetic and photosynthetic molecules. …

The Effect Of Water Flow Rates On The Survival And Growth Rates Of Three Caribbean Bouldering Coral Species Juveniles In An Indoor Versus Outdoor Environment, Ian Michael Johnson Aug 2023

The Effect Of Water Flow Rates On The Survival And Growth Rates Of Three Caribbean Bouldering Coral Species Juveniles In An Indoor Versus Outdoor Environment, Ian Michael Johnson

All HCAS Student Capstones, Theses, and Dissertations

Coral reefs are vital ecosystems for the world’s oceans and humanity; however, they are threatened by climate change, disease, and local anthropogenic stressors, and need assistance to recover. Traditional reef restoration efforts (fragmentation and outplanting are helping but are limited in effectiveness by not increasing genetic diversity. Ex situ sexual propagation for corals provides new, genetically different coral recruits. However, this process is laborious, expensive and time consuming, especially at the scale required to effectively contribute to the widespread recovery. To lower costs, two key parameters that require optimization to hasten the growth of coral recruits are water flow and …

Grasscheck: Monitoring And Predicting Grass Production In Northern Ireland, P. D. Barrett, A. S. Laidlaw Aug 2023

Grasscheck: Monitoring And Predicting Grass Production In Northern Ireland, P. D. Barrett, A. S. Laidlaw

IGC Proceedings (1997-2023)

Grass budgeting is a key management practice on dairy farms to balance grass supply on paddocks with grass demand by the grazing herd. Grass budgets must be pre-emptive to be effective. The uncertainty of grass production and the difficulty in quantifying both current and forecasted rates of growth hamper effective budgeting and paddock management. Grass growth rates are highly variable both in time and space. Therefore, they vary greatly between locations at any given time and also across the season at any given location. Figure 1 shows the pattern of growth rates recorded at the Agricultural Research Institute of Northern …

Managing The Reproductive Development Of Grasses By Grazing Practices, J. P. Theau, L. Chazelas, P. Ansquer, J. Viegas, O. Stefanini, M. L. Petit, P. Cruz, Michael Duru

IGC Proceedings (1997-2023)

Grazing natural grassland communities is necessary for both productive (feeding herbivores) and environmental (maintenance of open landscapes) objectives. Management guidelines should take into account the functional diversity of plant species between and within grassland communities. The management of the heading stage of grasses by grazing is an important tool to maintain acceptable forage quality and to avoid the seeding of low-valued species. The heading stage should be managed even in extensive systems and this needs a good knowledge of the phenological development of dominant species. In this work we illustrate the approach through the study of the development of four …

A Potential Role Of Gsk-3beta In The Development Of Pain Post-Spinal Cord Injury, Emily Ernst Apr 2023

A Potential Role Of Gsk-3beta In The Development Of Pain Post-Spinal Cord Injury, Emily Ernst

Undergraduate Theses

Chronic neuropathic pain is a very common consequence following spinal cord injury (SCI) and poses significant clinical challenge. Current treatments are largely ineffective and as a result, patients are often left with debilitating pain at and below the level of the spinal cord injury. After spinal injury, a cascade of events occurs within the nervous system. One important aspect of this cascade for investigation is the anatomical changes that occur post-SCI. There is evidence of maladaptive sprouting/growth in sensory nerve fibers that is thought to play a role in the development and amplification of pain signals. Sprouting of primary afferents …

Effects Of Forage Chicory (Cichorium Intybus) On Farmed Deer Growth And Internal Parasitism, S. O. Hoskin, P. R. Wilson, W. E. Pomroy, T. N. Barry Apr 2023

Effects Of Forage Chicory (Cichorium Intybus) On Farmed Deer Growth And Internal Parasitism, S. O. Hoskin, P. R. Wilson, W. E. Pomroy, T. N. Barry

IGC Proceedings (1997-2023)

Internal parasitism (particularly lungworm - Dictyocaulus sp) significantly limits post-weaning growth of deer. Endoparasite control using anthelmintics may be unsustainable, due to the increasing risk of anthelmintic resistance and the risk or perception of chemical residues in animal products. Chicory has a high feeding value and contains sesquiterpene lactones and low levels of condensed tannins, both with anti-parasitic activity (Molan et al., 2003). Grazing chicory during autumn may reduce the requirement for anthelmintic treatment of young deer compared with grazing ryegrass-based pasture (Hoskin et al., 1999). The objective of this study was to investigate the effect of withholding …
