Germinable Soil Seed Bank Of Bothriochloa Macra Dominated Pasture In South-Eastern Australia, M. L. Mitchell, J. M. Virgona, A. Durling, F. W. Dempsey

IGC Proceedings (1977-2023)

In native pastures, soil seed banks play an important role in conserving the genetic material in a plant population, influencing community structure and providing protection against adverse climatic conditions. One important native grass is Bothrichloa macra (Steud.) S.T.Blake (Red grass, Red-leg grass). This grass is a C₄ indigenous perennial grass that is commonly found in native pastures in the high rainfall zone of south-eastern Australia.

At Tarrawingee, NE Victoria, (36°25´S, 146°31´E) and Wymah, southern NSW, (35°58´S, 147°11´E), Australia, two sites that had Bothriochloa macra as the dominant native grass were sampled. Three hundred cores (50 mm diameter and 50 …

Carbon And Nitrogen Pools In Soil Aggregates Were Affected By Grazing Component ---- Results From Dry And Wet Sieving Methods, N. Liu, Y. Q. Wei, Y. Pang, B. Wei, Y. J. Zhang

IGC Proceedings (1977-2023)

Grazing intensity can affect soil carbon (C) sequestration in semiarid grassland, but less is known about the effects of grazing component (defoliation, trampling, excreta return and their combinations) on the C and Nitrogen (N) in soil aggregates. In this study, a simulated grazing experiment was established in a typical steppe of Inner Mongolia, and we investigated the impacts of different grazing component treatments on the different size of aggregates distribution and their C and N content from dry and wet physical separations. Different soil C fractions were showed in different sieving method. The C content of different aggregate size showed …

Sex Differences In Mitochondrial Function Following A Controlled Cortical Impact Traumatic Brain Injury In Rodents, Olivia J. Kalimon, Patrick G. Sullivan

Neuroscience Faculty Publications

Traumatic brain injury (TBI) is a complex disease to study due to the multifactorial injury cascades occurring after the initial blow to the head. One of the most vital players in this secondary injury cascade, and therapeutic target of interest, is the mitochondrion. Mitochondria are important for the generation of cellular energy, regulation of cell death, and modulation of intracellular calcium which leaves these “powerhouses” especially susceptible to damage and dysfunction following traumatic brain injury. Most of the existing studies involving mitochondrial dysfunction after TBI have been performed in male rodent models, leaving a gap in knowledge on these same …

Rails At Different Scales: Ecological And Evolutionary Drivers Of Vocal Behavior In Rallidae, Daniel Lorenz Goldberg

Theses and Dissertations

Animal signals used for communication, such as vocalizations and other sounds, are not produced in a vacuum, but evolve under a suite of selective pressures, including environmental and social factors, sender and receiver physiology, habitat features, and predation pressure, as well as phylogenetic history and morphological constraints. However, the extent to which these pressures have shaped the calling behavior of the avian family Rallidae is relatively unknown, despite the variety of different vocalizations of rails and the extent to which they use duetting and exhibit conspecific attraction. Here I answer a series of questions related to the adaptive drivers of …

Desktop Scanning Electron Microscopy In Plant-Insect Interactions Research: A Fast And Effective Way To Capture Electron Micrographs With Minimal Sample Preparation, Sakshi Watts, Ishveen Kaur, Sukhman Singh, Bianca Jimenez, Jesus Chavana, Rupesh R. Kariyat

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

The ability to visualize cell and tissue morphology at a high magnification using scanning electron microscopy (SEM) has revolutionized plant sciences research. In plant-insect interactions studies, SEM based imaging has been of immense assistance to understand plant surface morphology including trichomes (plant hairs; physical defense structures against herbivores (Kaur and Kariyat, 2020a, 2020b; Watts and Kariyat, 2021), spines, waxes, and insect morphological characteristics such as mouth parts, antennae, and legs, that they interact with. While SEM provides finer details of samples, and the imaging process is simpler now with advanced image acquisition and processing, sample preparation methodology has lagged. The …

Lack Of Interferon (Ifn) Regulatory Factor 8 Associated With Restricted Ifn-Γ Response Augmented Japanese Encephalitis Virus Replication In The Mouse Brain, Aarti Tripathi, Bhupendra Singh Rawat, Sankar Addya, Milan Surjit, Prafullakumar Tailor, Sudhanshu Vrati, Arup Banerjee

Kimmel Cancer Center Faculty Papers

Interferon regulatory factor 8 (IRF8), a myeloid lineage transcription factor, emerges as an essential regulator for microglial activation. However, the precise role of IRF8 during Japanese encephalitis virus (JEV) infection in the brain remains elusive. Here, we report that JEV infection enhances IRF8 expression in the infected mouse brain. Comparative transcriptional profiling of whole-brain RNA analysis and validation by quantitative reverse transcription-PCR (qRT-PCR) reveals an impaired interferon gamma (IFN-g) and related gene expression in Irf8 knockout (Irf82/2)-infected mice. Further, Ifng knockout (Ifng2/2) mice exhibit a reduced level of Irf8. Both Ifng2/2 and Irf82/2 mice exhibit significantly reduced levels of activated …

Predicting Carcass Cut Yields In Cattle From Digital Images Using Artificial Intelligence, Darragh Matthews, Thierry Pabiou, Ross D. Evans, Christian Beder, Aengus Daly

Department of Mathematics Publications

Deep Learning (DL) has proven to be a successful tool for many image classification problems but has yet to be applied to carcass images. The aim of this study was to train DL models to predict carcass cut yields and compare predictions to more standard machine learning (ML) methods. Three approaches were undertaken to predict the grouped carcass cut yields of Grilling cuts and Roasting cuts from a large dataset of 54,598 and 69,246 animals respectively. The approaches taken were (1) animal phenotypic data used as features for a range of ML algorithms, (2) carcass images used to train Convolutional …

Journal of Bioresource Management

The use of pesticides is becoming an indispensable technique in most agricultural practices, regardless of the level of development of the country. Currently, the pesticides used are often less toxic and more specific and are based on insect physiology. Recent studies indicate that pesticide intoxication induces oxidative stress. This work aims to study the neurobehavioral consequences of the administration of two insecticides currently widely used in agriculture: spirotetramat (an inhibitor of lipid synthesis in insects) and the ethanolic extract of Citrullus colocynthis (a plant endemic to the Algerian Sahara) and the ethanolic extract of Cleome arabica (Capparidaceae) The …

Plasmid Fitness Costs Are Caused By Specific Genetic Conflicts Enabling Resolution By Compensatory Mutation, Jpj Hall, Rct Wright, E Harrison, Kj Muddiman, Aj Wood, S Paterson, Ma Brockhurst

School of Biomedical Sciences

Plasmids play an important role in bacterial genome evolution by transferring genes between lineages. Fitness costs associated with plasmid carriage are expected to be a barrier to gene exchange, but the causes of plasmid fitness costs are poorly understood. Single compensatory mutations are often sufficient to completely ameliorate plasmid fitness costs, suggesting that such costs are caused by specific genetic conflicts rather than generic properties of plasmids, such as their size, metabolic burden, or gene expression level. By combining the results of experimental evolution with genetics and transcriptomics, we show here that fitness costs of 2 divergent large plasmids in …

Enhanced Grazing Management Assessment Using Drone-Based Lidar Measurements, V. W. Temu, W. C. Hession, P. Sforza, H. Wang

IGC Proceedings (1977-2023)

Globally, there is an urgent need of research-based technologies for small ruminant producers to benefit from rapidly growing market demands for ruminant meat and related food products from forage-based operations. However, effective forage-based animal production requires a rapid assessment, and monitoring of grazing management needs to adjust stocking rates and/or spatial animal distribution in a timely manner. Applicability of unmanned aerial vehicles (drones) for grazing management offers opportunities to rapidly estimate biomass build-ups, ground coverage, and monitor animal behaviour. The reliability of drone-based laser scanning (DLS) for monitoring warm-season grass responses to simulated grazing intensities was assessed at Virginia State …

Ecorestore: Decision Support System To Restore The Productivity Of Degraded Rangelands In Southern Africa, Klaus Kellner, Dirk Pretorius, C. Marais

IGC Proceedings (1977-2023)

Land degradation is a multifaceted problem that affects the agricultural productivity of land due to a loss of vegetation cover and can often be ascribed to bush encroachment in savanna and grassland rangelands. Bush encroachment entails the increase in abundance and density of indigenous and alien woody vegetation (i.e. shrub thickening), which has a negative impact on the tree-grass ratio, biodiversity, as well as on a range of ecosystem services that affect the well-being of land users, often causing an increase in poverty and the introduction of non-sustainable land management practices, especially in arid- and semi-arid regions mostly affected by …

Rangeland Management In A Changing World – Active And Passive Restoration Case Studies From Ethiopia, Tanzania, And South Africa, A. C. Treydte, S. A. Baumgartner, S. K. Tuffa, A. A. Abdeta

IGC Proceedings (1977-2023)

Rangelands cover almost 50% of the earth’s land surface and are often found in marginal areas that often face climate extremes. The production of herbaceous biomass has strongly declined over the last decades due to overgrazing and adverse climatic conditions such as frequent droughts and flooding. While different rangeland restoration methods are being used, their effect on vegetation quality and quantity over time has rarely been experimentally tested and monitored. Our research comprises experiments of various rangeland restoration tools we have used across eastern and southern Africa. We conducted passive restoration through exclosure experiments and compared vegetation in and outside …

Counteracting Green Alder Shrub Expansion By Low-Input Grazing, M. K. Schneider, T. Zehnder, J. Berard, C. Pauler, M. Staudinger, Michael Kreuzer, A. Lüscher

IGC Proceedings (1977-2023)

In the past decades, the decline of traditional agriculture has caused an abandonment of marginal pastures in many mountain areas of Europe. In the Swiss Alps, green alder (Alnus viridis) is the most abundant successional shrub. A survey of 24 pasture-shrub gradients showed that the encroachment by green alder, in contrast to other shrubs, is associated with a substantial decline in plant species richness. The understorey of alder is primarily populated by very few, broad-leaved herbaceous species benefitting from the atmospheric nitrogen fixed by actinomycetes in symbiosis with green alder. However, the understory vegetation also provides an underestimated …

Bee-Friendly Beef: Developing Biodiverse Pastures To Increase Ecosystem Services, J. Wagner, S. Ghajar, M. O’Rourke, B. Tracy

IGC Proceedings (1977-2023)

The capacity of grasslands to provide ecosystem services, such as pollinator resources, is often limited by lack of plant biodiversity. This is true of grasslands in the eastern US that are dominated by tall fescue (Festuca arundinacea) a non-native, cool-season grass that is typically toxic to cattle. This paper summarizes a research project in Virginia, USA exploring the idea that ecosystem services provided by tall fescue-dominated grasslands can be improved by increasing the plant biodiversity available to beef cattle and bees. Within three 6.5 ha tall fescue grasslands, we established 0.8 ha plots with a 17 species mix …

Rangeland In Marajó Island, Brazilian Amazon, A Long History Of Commons For Small-Breeders, T. Barbosa, M. Opplert, R. Folhes, S. Carvalho, Jean François Tourrand

IGC Proceedings (1977-2023)

Rangelands cover almost one third of the earth's surface and are characterized by a low productivity and high sociocultural value. But the lack of recognition of the environmental, social and economic values of rangelands, along with the expansion of agribusiness, tourism and urban sprawl give rise to a rangeland dilemma. This dilemma is found in various regions of the world, where this set of factors leads to the generally irreversible destruction of the rangeland. The process is recent in the Amazon rangeland, such as the eastern part of Marajó Island and the Low Amazon wetlands. A survey conducted on 90 …

Effects Of Herding On Rangeland Use Efficiency In Kenya, A. Seidel, F. Asch, B. Warth

IGC Proceedings (1977-2023)

Within each foraging itinerary, herders can intervene in the forage selection process, encouraging herds to use highly palatable and less palatable rangeland resources. Such a herding strategy could prevent rangeland degradation and increase livestock productivity. The objectives of this study were to examine forage availability and identify factors influencing stocking rates around night resting places on a ranch in Laikipia County, Kenya.

Forage availability was measured along six regularly spaced transects around night resting places corralling one herd of camels, one mixed herd of goats and sheep, and two herds of cattle, with biomass sampling points at 50-, 150-, 250-, …

Livestock Policy In Special Areas, Alberta, Canada, P. L. Strankman

IGC Proceedings (1977-2023)

Special Areas, Alberta, Canada, is a rural municipality of 2.1 million hectares (about 5 million acres) in south-eastern Alberta. It is home to almost 5000 residents, with a unique governance arrangement in Alberta. Most of the farms and ranches utilize a mix of crop and livestock primarily annual cereal and oil seed cultivation and beef cattle. These production units are usually a mosaic of privately-owned land and Crown land leased from the government.

It provides an interesting case study for the local, and national challenges facing western Canadian agriculture. It also provides an opportunity to contrast with different bioclimatic and …

Collaborative Construction Of A Method That Contributes To Improve The Decision Making In Associative Ranches By Controlling The Grass Allowance In A Context Of Climate Variability, Emilio Duarte Esteves, Rómulo Cesar, Javier Fernández, Marcelo Ghelfi, Valentina Herrera, Virginia Caravia, Rodrigo Iribarne, Federico De Brum, Héctor Rodríguez, Marcelo Pereira Machín

IGC Proceedings (1977-2023)

Pasture management and the particular conditions of each year are responsible for productive results, farm income, and condition of the pasture. A simple and robust method that relates the available grass and the required grass was built in a participatory manner, and contributes to a critical reflection process among the group of decision-making, adapting to their context. In 17 farms from the Basalt region in Uruguay, grass and animals were monitored seasonally. A simple method was developed with farmers, and from de offer needed to meet production targets (KgMS/KgPV) the amount of grass requires was calculated. The grass height was …

Cruise Of The Minnehaha, Pat Dodson

Florida Historical Quarterly

In the winter of 1891-1892 four men— three brothers, Stanley, Robert, and Edward Bullock, and their friend, A. E. Woodham — sailed a thirty-foot sloop, the Minnehaha, from Narcoossee on East Lake Tohopekaliga on a round trip down the Kissimmee River to Lake Okeechobee and out to the Gulf of Mexico via the Caloosahatchee River. They began the trip that fall down the Kissimmee River, opened a few years before by Hamilton Disston’s dredges. Leaving November 26, they reached Marco on January 9 and returned home February 8. They followed a tortuous route, covering about 1,000 miles in seventy-three days.
