Identifying Target Traits For Forage Grass Breeding Under A Changing Climate In Norway Using The Basgra Model, Mats Höglind, Tomas Persson, Marcel Van Oijen

IGC Proceedings (1977-2023)

Grass-based dairy and livestock production constitutes the most important agricultural sector in Norway in economic terms, and 60% of the agricultural land in Norway is used for grass production. Climate change may have consider-able impact on the survival and productivity of grasslands, with consequences for the local supply of forage to live-stock, farmers’ income and the supply of dairy- and livestock-based food products to the global market. Farmers can adapt to climate change by choosing different grass species or cultivars or by changing management practices such as the timing and frequency of harvests. Plant breeders select new cultivars of grasses …

Infant mortality, ineffective ante- and post-maternal healthcare and stagnated development in Nigeria are decades old concerns that need urgent redress. High rates of infant mortality and inability of pregnant women to access healthcare implicate children’s life chances, maternal psychosocial and economic wellbeing, future family welfare, community and national development prospects. Healthcare practices of the present constitutes the foundation for future child, family and overall development. Principally, this empirical research examines Nigeria’s critical dimensions of infant mortality and access to primary health centers (PHCs) as behavioral tendencies capable of shaping the present and future of infancy, childhood, the family and the …

Beyond Feminism: The Egg As A Symbol Of The Brazilian Dictatorship In The Work Of Anna Maria Maiolino, Mónica Lindsay-Pérez

Journal of International Women's Studies

So easy to break and yet impossible to fix, the egg is, in itself, a contradiction: soft but hard; delicate but durable; impermanent but episodic. One of nature’s most interesting creations, it is impossibly bigger on the inside than the outside and has accordingly captivated artists’ minds throughout history. Artists have employed the egg as an allegorical tool for its religious, surrealist, or feminist connotations. Ana Maria Maiolino, a Brazilian artist born in 1942, pushed the egg metaphor beyond its most common iconographic meanings. For the artist, the egg was not simply a religious, philosophical, or feminist symbol, but also …

Moreta, Hernán Lopez, Aracely Castro, Rein Van Der Hoek, Siriwan Martens, Glenn Hyman, Jeimar Tapasco, Jorge Duitama, Harold Suarez, Gonzalo Borrero, Jonathan Núñez, Katharina Hartmann, Moralba Dominguez, Mauricio Sotelo, Daniel Vergara, Patrick Lavelle, Guntur V. Subbarao, Alvaro Rincon, Camilo Plazas, Reynaldo Mendoza, Lena Rathjen, Georg Cadisch

IGC Proceedings (1977-2023)

It is widely recognized that less than 50% of applied nitrogen (N) fertilizer is recovered by crops, and based on current fertilizer prices the economic value of this “wasted N” globally is currently estimated as US$81 billion annually. Worse still, this "wasted" N has major effects on the environment (Subbarao et al. 2012). CIAT researchers and their collaborators in Japan reported a major breakthrough in managing N to benefit both agriculture and the environment (Subbarao et al. 2009). Termed "Biological Nitrification Inhibition" (BNI), this natural phenomenon has been the subject of long-term collaborative research that revealed …

Root Decomposition Of Elephant Grass Pastures Grazed At Different Management Intensities, José C. B. Dubeux Jr., Hiran Marcelo Siqueira Da Silva, Maria Lúcia Silveira, Erinaldo Viana De Freitas, Mércia V. F. Dos Santos, Alexandre C. L. De Mello

IGC Proceedings (1977-2023)

Grazing management may alter chemical composition of plant components affecting nutrient cycling. Among pasture management tools, adjustment of stocking rate (SR) and N fertilization have potential to affect nutrient cycling in the grassland ecosystem (Dubeux et al. 2007). Excreta from grazing animal and litter are the two major pathways of nutrient return on grazed pastures (Thomas 1992). Fertilization and SR may alter these pathways by different forms. Increasing fertilization generally increases pasture net primary productivity. Stocking rate affects different pasture and animal responses. Regarding nutrient cycling, increasing SR will likely increase proportion of nutrient returned through excreta as opposed …

Effects Of Nitrogen Supply And Nitrogen Form On Intrinsic Water-Use Efficiency In Temperate, Semi-Natural Grasslands Under Rising Atmospheric Co2, Iris H. Köhler, Andy Macdonald, Hans Schnyder

IGC Proceedings (1977-2023)

Carbon uptake and water loss of plants are controlled by the regulation of carbon assimilation rate (A) and stomatal conductance (g_s). Any changes in these parameters under rising atmospheric CO₂ concentration (c_a) influence plant water-use efficiency and can affect carbon and water relations in grassland ecosystems. Time-series analyses of intrinsic water-use efficiency (W_i) of C3 grassland vegetation during the 20^th century have shown that carbon uptake relative to water loss generally increased (Köhler et al. 2010, 2012; Barbosa et al. 2010). Short-term experiments suggest that nitrogen …

Climagie: A French Inra Project To Adapt The Grasslands To Climate Change, Jean-Louis Durand, Jérome Enjalbert, Laurent Hazard, Isabelle Litrico, Catherine Picon-Cochard, Marie-Pascale Prudhomme, Florence Volaire

IGC Proceedings (1977-2023)

Climate change in France, central and southern Europe is expected to provoke more frequent and more intense summer water deficits, with increased amplitude in temperatures, exposing the same perennial crops to frosts as well as to heat waves and severe droughts. The impacts on sown monospecific grasslands have been assessed using crop models (Durand et al. 2010) but with less accuracy in extreme situations. Since less work has been done on intra-specific genetic variability there is urgent need to investigate both ranges of climate conditions and genetic variability (Poirier et al. 2012). Phenology and plant productivity responses to …

Assessment Of Harvest Security Of Timothy Under Climate Change Condition Using A Set Of Simple Criteria, Tomas Persson, Mats Höglind

IGC Proceedings (1977-2023)

According to climate change projections, the conditions for forage grass production in Northern Europe, including Norway, will change dramatically during the 21st century. The projected changes in climate in this country include increased average annual air temperature as well as increased precipitation both during the summer and winter season (Hansen-Bauer et al. 2009). In previous studies, effects of projected climate change on the above-ground biomass production, winter survival and harvest security of forage grasses have been assessed (Thorsen and Höglind 2010; Höglind et al. 2013). For example, Persson and Höglind (2013) showed a decreased dry spell period and …

Growing Biofuel Feedstocks In Copper-Contaminated Soils Of A Former Superfund Site, Virinder Sidhu, Dibyendu Sarkar, Rupali Datta

Michigan Tech Publications, Part 1

Copper mining in the Upper Peninsula of Michigan in the mid-19th century generated millions of tons of mining waste, called stamp sand, which was deposited into various offshoots of Lake Superior. The toxic stamp sand converted the area into barren, fallow land. Without a vegetative cover, stamp sand has been eroding into the lakes, adversely affecting aquatic life. Our objective was to perform a greenhouse study, to grow cold-tolerant oilseed crops camelina (Camelina sativa) and field pennycress (Thlaspi arvense) on stamp sand, for the dual purpose of biofuel production and providing a vegetative cover, thereby decreasing erosion. Camelina and field …

Comparative Analysis Of Climate Change Adaptation Options Across The Southern Australian Livestock Industry, Afshin Ghahramani, Andrew D. Moore

IGC Proceedings (1977-2023)

Climate change is predicted to have a substantial negative effect on the productivity of grasslands across southern Australia (Moore and Ghahramani 2013). We used the GRAZPLAN biophysical simulation models to assess several possible grassland management and animal genetic improvement adaptations under SRES A2 climate change scenario. Simulations spanned the five dimensions of geography, time, global circulation models, enterprise, and adaptations. Impact of climate change was predicted to reduce profitability of livestock industry by 46%, 58%, and 72% at 2030, 2050 and 2070, respectively. Increasing soil fertility could return the average profitability of five livestock enterprises to its historical level at …

Eco-Efficiency Of Forage Production In Northern Germany, Antje Herrmann, Sandra Claus, Christof Kluß, Friedhelm Taube

IGC Proceedings (1977-2023)

A 2-year field experiment was conducted at two sites in Schleswig-Holstein, northern Germany, to quantify and evaluate the carbon footprint of arable forage cropping systems (continuous silage maize, maize-wheat-grass rotation, perennial ryegrass ley) as affected by N fertilizer type and N amount. Total greenhouse gas emission showed a linear increase with N application, with mineral N supply resulting in a higher slope. Product carbon footprint ranged between -66 and 119 kg CO2eq/(GJ NEL) and revealed a quadratic or linear response to fertilizer N input, depending on the cropping system. At N input required for achieving maximum energy yield, perennial ryegrass …

Elevated Co2 Impacts On Grazed Pasture: Long-Term Lessons From The New Zealand Face, Michael B. Dodd

IGC Proceedings (1977-2023)

A grazed pasture Free Air CO₂ Enrichment (FACE) experiment has been operating for almost 15 years in the Rangitikei Region of New Zealand, following earlier work studying CO₂, temperature and moisture effects on pasture in growth chambers. The longer-term results are reviewed with a focus on primary productivity, pasture compositional dynamics, nutrient cycling feedbacks and soil carbon supply. In terms of the direct effects of CO₂ elevated to 475 ppm, increases in primary production were reflected in belowground allocation and legume stimulation, with the latter diminishing in the longer term and annual aboveground net herbage accumulation …

Plant–Soil Feedback Effects Altered By Aboveground Herbivory Explain Plant Species Abundance In The Landscape, Johannes Heinze, Alexander Wacker, Andrew Kulmatiski

Ecology Center Publications

Relatively little is known about how plant–soil feedbacks (PSFs) may affect plant growth in field conditions where factors such as herbivory may be important. Using a potted experiment in a grassland, we measured PSFs with and without aboveground insect herbivory for 20 plant species. We then compared PSF values to plant landscape abundance. Aboveground herbivory had a large negative effect on PSF values. For 15 of 20 species, PSFs were more negative with herbivory than without. This occurred because plant biomass on “home” soils was smaller with herbivory than without. PSF values with herbivory were correlated with plant landscape abundance, …

Pcr Cloning Combined With Dna Barcoding Enables Partial Identification Of Fish Species In A Mixed-Species Product, Anthony J. Silva, Michael D. Kawalek, Donna M. Williams-Hill, Rosalee S. Hellberg

Food Science Faculty Articles and Research

DNA barcoding is a valuable tool for regulatory identification of fish species; however, it does not perform well when multiple species are present within the same food product. Therefore, the objective of this study was to examine the use of PCR cloning to identify fish in a mixed-species product that cannot be identified with standard DNA barcoding. A total of 15 fish ball mixtures were prepared with known amounts of Nile tilapia (Oreochromis niloticus), Pacific cod (Gadus macrocephalus), and walleye pollock (Gadus chalcogrammus). Three subsamples from each fish ball underwent DNA extraction, full DNA barcoding (655 bp), and mini-barcoding (226 …

Oxidant Stress And Renal Function Among Children With Chronic Kidney Disease: A Repeated Measures Study., Melanie H. Jacobson, Mengling Liu, Yinxiang Wu, Susan Furth, Bradley A. Warady, Howard Trachtman, Leonardo Trasande

Manuscripts, Articles, Book Chapters and Other Papers

It is hypothesized that chronic kidney disease (CKD) induces oxidant stress which contributes to the decline in kidney function. However, few studies have incorporated longitudinal designs and no studies have investigated this association among children. Using data from the Chronic Kidney Disease in Children (CKiD) study, we examined longitudinal associations between urinary biomarkers of oxidant stress, 8-OH deoxyguanosine (8-OHdG) and F2-isoprostane, and measures of renal function and blood pressure among children with CKD. Baseline levels of 8-OHdG were positively associated with estimated glomerular filtration rate (eGFR) over time and a log-unit increase in baseline 8-OHdG predicted a 5.68 ml/min/1.73 m2 …
