Effects Of Harvest Frequency On Yield And Self-Thinning In Irrigated Orchardgrass (Dactylis Glomerata L.) In Oregon, Usa, G. Jones

IGC Proceedings (1977-2023)

Persistence is an important factor in the economic management of perennial grass swards. Frequent harvest is occasionally attributed to poor stand persistence, but self-thinning theory indicates that infrequent harvest should cause swards to thin as tillers compete for light. This experiment aimed to demonstrate and qualify self-thinning in orchardgrass managed under differing harvest frequencies. Orchardgrass was planted in September 2018 and then clipped, fertilized and divided into experimental units in March 2019. Plots were randomly assigned one of four harvest frequency treatments (n = 5): No harvest, one harvest, two harvests, and four harvests. Irrigation water and fertilizer were …

State And Transition Models In Space And Time – Using Stms To Understand Broad Patterns Of Ecosystem Change In Iceland, I. C. Barrio, D. S. Hik, T. A. Mulloy, J. Thorsson, K. Svavarsdóttir, B. Marteinsdóttir, I. S. Jónsdóttir

IGC Proceedings (1977-2023)

Managing ecological systems sustainably requires a deep understanding of ecosystem structure and the processes driving their dynamics. Conceptual models can lead to improved management, by providing a framework for organizing knowledge about a system and identifying the causal agents of change. We developed state-and-transition models (STMs) to describe landscape changes in Iceland over three historical periods with different human influence, from pre-settlement to present days. Our models identified the set of possible states, transitions and thresholds in these ecosystems and their changes over time. To illustrate the use of these models for predicting and improving management interventions, we applied our …

Soil Water Movement In A Watershed In The Chilean Patagonia, J. Ivelic-Sáez, P. Cisternas, J. Dörner, J. Arumí, J. Valenzuela, E. Muñoz, S. Valle, H. Alonso, R. López, H. Uribe

IGC Proceedings (1977-2023)

Magallanes region, located southern Chile, contains about 1.9 million sheep heads, in about 5 million hectares of rangelands. However, forage production is concentrated in small wetlands meadows called locally “Vegas” that only represent about 300.000 hectares. Those ecosystems that sustain patagonian ranches, produce 20 times more forage biomass than the surrounding natural rangelands. Patagonian vegas have concave topography with a hydrophyte (wet) center, and mesic slopes and xeric highlands of Festuca gracillima. Although the moisture content is controled by topography, there is scarce information about the movement of water through this concave topography. Also, the spatial variability of the …

Simple Guidelines For Deciding When Soil Variability Does – And Doesn’T – Matter For Rangeland Management And Restoration, Jeff E. Herrick, J. Maynard, B. Bestelmeyer, A. Ganguli, J. Glover, K. Johnson, D. Kimiti, J. Neff, G. Peacock, J. Peters, S. Salley, P. Shaver, K. Shepherd, Z. Stewart, R. Van Den Bosch

IGC Proceedings (1977-2023)

“Rangelands in most parts of the world are relatively homogenous and can be managed uniformly at the landscape scale” or “rangelands are extremely diverse and require different approaches even at the landscape scale.” Both statements are made frequently by rangelands scientists and managers. Both are correct. Whether or not it is worthwhile to consider soil variability when planning management and restoration at the landscape scale depends on objectives, location, and the management or restoration strategies under consideration. Together these factors determine whether outcomes are likely to be different at different locations in the landscape, and whether those outcomes can be …

Effects Of Banana Peels On Chicken Weight Gain And Egg Production In The Urban And Peri-Urban Areas Of Aksum City, Ethiopia, H. G. Araya, S. G. Gebrekristos, W. V. Oliver

IGC Proceedings (1977-2023)

High feed cost of running urban-animal-agriculture and huge city wastes are challenges of the growing towns in modern Ethiopia. Egg production microenterprise is steadily growing due to its low initial investment and ready market in urban and peri-urban areas. However, cost of egg production is high due to the rising cost of corn, the main feed ingredient in poultry rations. Using banana peels, which forms a great proportion of city waste in Ethiopia, is seen as a way of not only reducing the waste, but also as an alternative low-cost feed supplement that could help enhance egg production by small-holder …

Relationship Of Dag1 And Serpina5 Sperm Proteins With Bull Fertility, Saulo Menegatti Zoca, Julie Walker, Jerica J. J. Rich, Kaitlin M. Epperson, Taylor N. Andrews, Adalaide C. Kline, Jessica Nora Drum, M. Sofia Ortega, George Perry

SDSU Beef Day 2022 Summary Publication

Study Description:

Semen from 22 dairy bulls was used to evaluate the presence, localization, and quantification of DAG1 and SERPINA5 on sperm. Sperm motility parameters and viability was also evaluated for semen from each bull. Semen from 19 out of the 22 dairy bulls was used for in vitro embryo production (two Low-SCR and one High-SCR were not available for in vitro embryo production). Bulls were classified based on their sire conception rates (SCR) values as High-SCR (SCR > 1.0) or Low-SCR fertility (SCR < -4.0). Low fertility bulls were subdivided based on their blastocyst rate (BL) as High-BL (Low-SCR/High-BL BL ≥ 31%) or Low-BL (Low-SCR/Low-BL BL ≤ 26%), and High-SCR bulls were not subdivided. The GLM procedure in SAS was used with bull as a fixed effect to determine if variance was greater between bulls compared to within bull. Correlations were determined among DAG1 and SERPINA5 concentrations, percentage of tail labeled for SERPINA5, SCR, sperm total motility, progressive motility, and viability, and in vitro embryo produced cleavage rate (CL) and BL. The GLIMMIX procedure of SAS was used to evaluate the relationship of bull field fertility (High- and Low-SCR), and field and in vitro fertility (High-SCR, Low-SCR/High-BL, Low-SCR/Low-BL) classifications with sperm total (TMOT) and progressive (PROG) motility, viability, CL, BL, DAG1 and SERPINA5 relative concentration, and proportion of sperm tail labeled for SERPINA5. Both SERPINA5 and DAG1 were localized on the sperm head; however, SERPINA5 was also localized on the sperm tail. There was greater variance in concentration among bulls compared to within bull for both DAG1 (P < 0.01; 69.4 vs 49.1, respectively) and SERPINA5 (P < 0.01; 325.8 vs 285.4, respectively). There was a positive correlation between concentration of DAG1 and SERPINA5 (P = 0.01; r = 0.54). Concentrations of SERPINA5 were also correlated with CL (P = 0.04; r = 0.48), and percentage of sperm tail labeled for SERPINA5 was correlated with viability (P = 0.05; r = 0.44) and tended to be correlated with CL (P = 0.10; r = 0.39). There was no relationship between SCR or BL rate classifications and DAG1 (P ≥ 0.66), SERPINA5 (P ≥ 0.54), or percentage of sperm tail labeled for SERPINA5 (P ≥ 0.48).

RATIONALE: Dextro-transposition of the great arteries (D-TGA) is a severe congenital heart defect which affects approximately 1 in 4,000 live births. While there are several reports of D-TGA patients with rare variants in individual genes, the majority of D-TGA cases remain genetically elusive. Familial recurrence patterns and the observation that most cases with D-TGA are sporadic suggest a polygenic inheritance for the disorder, yet this remains unexplored.

OBJECTIVE: We sought to study the role of common single nucleotide polymorphisms (SNPs) in risk for D-TGA.

METHODS AND RESULTS: We conducted a genome-wide association study in an international set of 1,237 patients …

A Kinematic And Emg Dataset Of Online Adjustment Of Reach-To-Grasp Movements To Visual Perturbations, Mariusz P. Furmanek, Madhur Mangalam, Matthew Yarossi, Kyle Lockwood, Eugene Tunik

Journal Articles

Control of reach-to-grasp movements for deft and robust interactions with objects requires rapid sensorimotor updating that enables online adjustments to changing external goals (e.g., perturbations or instability of objects we interact with). Rarely do we appreciate the remarkable coordination in reach-to-grasp, until control becomes impaired by neurological injuries such as stroke, neurodegenerative diseases, or even aging. Modeling online control of human reach-to-grasp movements is a challenging problem but fundamental to several domains, including behavioral and computational neuroscience, neurorehabilitation, neural prostheses, and robotics. Currently, there are no publicly available datasets that include online adjustment of reach-to-grasp movements to object perturbations. This …
