A Comparative Review Of Soil Carbon Sequestration Methods In Brazil’S Agriculture, Skylar Cheng

Discussions

Brazil is under unique pressure to adopt sustainable agricultural practices due to its intricate biodiversity and globally dominant agricultural sector. Increasing soil degradation, agricultural land expansion, and rising levels of atmospheric carbon are nationwide concerns that require multifaceted solutions. Integrated agricultural systems, which rehabilitate soils through crop, forage, and livestock rotation as well as biochar—a carbon-rich soil amendment—can address such concerns. These sustainable farming practices improve carbon sequestration and soil fertility; however, uptake remains minimal due to environmental, economic, and policy barriers. Accordingly, this paper proposes a comprehensive model of integrated systems and biochar, in which the benefits of one …

Children’s Nutrition Research Center Staff Publications

Declined memory is a hallmark of Alzheimer’s disease (AD). Experiments in rodents and human postmortem studies suggest that serotonin (5-hydroxytryptamine, 5-HT) plays a role in memory, but the underlying mechanisms are unknown. Here, we investigate the role of 5-HT 2C receptor (5-HT2CR) in regulating memory. Transgenic mice expressing a humanized HTR2C mutation exhibit impaired plasticity of hippocampal ventral CA1 (vCA1) neurons and reduced memory. Further, 5-HT neurons project to and synapse onto vCA1 neurons. Disruption of 5-HT synthesis in vCA1-projecting neurons or deletion of 5-HT2CRs in the vCA1 impairs neural plasticity and memory. We show that a selective 5-HT2CR agonist, …

It has persisted in these communities after centuries of grazing or cutting, without fertiliser input. T. ambiguum ploidy levels were predominantly diploid (82% frequency of occurrence), often in conjunction with triploid (18%) or tetraploid (27%) genotypes. The triploid T. ambiguum genotype ( …

Nitrogen Nutrition Of Brant (Branta Bernicla L.) Grazing On Saltmarsh And Pasture Species, G Q.A Anderson, M Andrews, S M. Percival, J S. Kirby

IGC Proceedings (1977-2023)

Captive brant Branta bernicla were fed a range of food plants to determine their ability to digest nitrogen and specifically soluble protein. Soluble protein levels in droppings were only a small fraction of those in plants, indicating substantial uptake or conversion. For white clover Trifolium repens L., uric acid content indicated that at least 50% of excreted nitrogen had been metabolised, strongly suggesting that a substantial fraction of soluble protein is utilised by the geese. Carbon/nitrogen ratios increased from plants to droppings while carbon/hydrogen ratios remained nearly constant indicating greater uptake of nitrogen relative to carbon. T. repens was found …

Evaluation Of Morphological, Biological And Chemical Properties For Breeding On New Fodder-Grass Cultivars, S Kozlowski, B Golinska, P Golinski

IGC Proceedings (1977-2023)

Our work is an attempt to emphasize the importance of grass morphological, biological and chemical properties in the process of development of new forage cultivars. Results of our investigations indicate that there are realistic possibilities of developing grass cultivars with improved nutritive properties. However, breeding works can only be effective if a wide range of different properties can be taken into consideration and if, simultaneously, mutual correlations occurring between them are also considered. High mutability of properties revealed by lower taxonomic units of the species observed in Poland indicates that they can constitute a valuable material for breeding work on …

Alfalfa Seeding Patterns And Their Relations With Vegetative And Reproductive Development, R B. Medeiros, A.V A. Jacques, C Nabinger

IGC Proceedings (1977-2023)

This study was conducted to understand how plant density (17, 61 and 89 plants m-2) and row spacing (30 and 90 cm) affect plant development and the consequences on potential seed yield (PSY) and agricultural realized seed potential (ARSP) of alfalfa (Medicago sativa L.) in south Brazil. Both variables were not affected by row spacing but were negatively correlated to plant population. This was a consequence of a higher allocation of assimilates to reproductive structures at low plant competition, denoted by a positive correlation between these two variables and reproductive parts growth rate. Despite the benefits of the low plant …
