Reserve Mobilization During Regrowth After Cutting Of Forage Species: Quantification And Physiological Mechanisms In Ryegrass And Lucerne, A Ourry, J Bigot, T Kim, J Boucaud, J Salette

IGC Proceedings (1977-2023)

Time course of remobilisation of reserves was studied during the regrowth of Loli11m perem1e and Medicago sativa by 15N labelling, carbohydrate analyses and by measuring time course of several enzymes activities. When photosynthesis decreased during early regrowth, and consequently reduced availability of carbon skeletons within the plant, both nitrogen (N) uptake (lolium perene) and N2 fixatlon (Medicago saliva) decreased. Nilrogenase, as well as nitrate reductase activities, decreased. Reduction of external N assimilation was compensated for by intensive mobilization of endogenous N in roots of lucerne and in stubble of ryegrass. In the same manner, some of …

Bermudagrass Allelochemistry And Influence On Spodoptera Frugiperda Herbivory, S Quisenberry, M Mohamed

IGC Proceedings (1977-2023)

Cultivated area of bermudagrass (Cynodon dactylon L. Pers.), in the USA are under stress from a complex of insect and secondary fungal pests which has resulted in a loss in crop production. The fall armyworm (Spodoptera frugiperda (J.E. Smith)) is the major insect herbivore of bermudagrass in the south-eastern USA. Bermudagrass breeding programmes over the last decade have yielded germplasm with potential insect-resistant traits. Thus, a programme was initiated to define bermudagrass allelochemislry with respect to insect herbivory. Pall armyworm is variably responsive to bermudagrass cultivars, the basis being causally related to a differential concentration of the phagostimulant 6, …

A Bayesian Semi-Parametric Scalar-On-Function Regression With Measurement Error Using Instrumental Variables, Roger S Zoh, Yuanyuan Luan, Lan Xue, David B Allison, Carmen D Tekwe

Children’s Nutrition Research Center Staff Publications

Wearable devices such as the ActiGraph are now commonly used in research to monitor or track physical activity. This trend corresponds with the growing need to assess the relationships between physical activity and health outcomes, such as obesity, accurately. Device-based physical activity measures are best treated as functions when assessing their associations with scalar-valued outcomes such as body mass index. Scalar-on-function regression (SoFR) is a suitable regression model in this setting. Most estimation approaches in SoFR assume that the measurement error in functional covariates is white noise. Violating this assumption can lead to underestimating model parameters. There are limited approaches …

Michelle Harris, Tia D. Jeffery, Pier Broadnax

Journal of Extension

Physical activity (PA) rates among older adults are low. We examined and compared the PA needs, preferences, and practices of 118 rural- and urban-residing older adults through focus groups and surveys. The sample was diverse (White = 42.4%, Black = 37.3%), mostly female, food-secure, and not meeting PA recommendations (38.1%). PA rates were lower for rural-residing older adults (p < 0.05). PA motivators were health benefits and socialization, while barriers were cost, pain, low motivation, and health limitations. Preferred PA programs were described as age-appropriate, expert-led, and group-based. These findings provide insight regarding what to consider when planning PA programming for community-residing older adults.

Crisis Of Youth Homelessness In Birmingham, Alabama, Velma Annette Williams

Doctoral Dissertations and Projects

The economic and educational conditions of Jefferson County, Alabama, have contributed significantly to the increase of homeless families with children (LaGory et al., 2018). The failures of the foster care system have exponentially increased the population of homeless youth ages 19 to 26 (Burge et al., 2021). The lack of efficient public transportation emergency and affordable long-term housing has created a permanent population of homelessness (Kelly, 2020). Within the homeless culture, the increased incidents of violence, substance abuse, and sexual and physical abuse combined with functional illiteracy create an environment that breeds repetitive behaviors that reproduce the homeless outcomes (Burge …
