Factors Affecting Honey Bee (Apis Mellifera L.) Health As Perceived By South Georgia Commercial Beekeepers, Kimberly Post
The Journal of Extension
Honey bees (Apis mellifera L.) are critical to the pollination of many crops. Bee-oriented organizations survey beekeepers annually to gather information about colony loss and contributing factors. Unfortunately, these surveys provide insufficient data from sideliner and commercial beekeepers in Georgia. Through a survey to better understand South Georgia beekeepers’ perceptions of honey bee health, this project engaged a previously underrepresented group of sideliner and commercial beekeepers.

Impact Of Cover Crop Species Diversity On Soil Nutrient Availability And Crop Productivity, Amanda Kramer
Masters Theses
Cover crops provide multiple environmental benefits that improve both soil and water quality; however, farmers only utilize them on approximately 5% of harvested U.S. cropland. Low adoption rates are attributed to yield impact concerns, seed and planting costs, and lack of advocacy. This study, which began in October 2019, assessed the effects of nitrogen rate and cover crop diversity on weed biomass, soil coverage, in-situ residue decomposition, soil nitrogen and phosphorus availability, and cash crop yield to better understand the costs and benefits of cover crop adoption at two locations in Tennessee (Milan and Spring Hill). Treatments were replicated 4 …

Entomology Research Data
An organism’s ability to respond to changing conditions can be vital to its success. Indeed, plasticity is a common feature of living organisms. Much of the research in this area, though, has focused on effects caused by environmental conditions. What has received relatively less attention is how social experiences and broader features of an organism’s social environment can lead to long-lasting changes in health and behavior. This knowledge gap exists despite the well-documented existence of health and behavioral effects after social interactions in certain taxa such as humans.
Social insects such as honey bees provide an excellent opportunity to better …

Palatability, Consumption, And Physiological Effects Of The Green Microalgae Chlorella Sp. As A Feed Substitute For The Western Honey Bee Apis Mellifera In A Laboratory Setting, Benjamin J. Nichols
Department of Entomology: Distance Master of Science Projects
Western honey bees Apis mellifera are vital pollinators which play a significant role in global food security. Honey bees are faced by numerous environmental pressures including lack of forage which lead to large losses annually of managed honeybee colonies. To offset these pressures, many beekeepers manage colonies with the addition of artificial diets, many of which contain products that do not meet the nutritional requirements needed by honey bees or require large amounts of resources to grow. Recent literature has indicated that algae may be a viable nutritional resource for honey bees, meeting the nutritional requirements needed, requiring less resources, …

Journal of Bioresource Management
Soils have the most diversified microbial communities of any environment on the planet. Bacteria, fungi, algae, and protozoa are all found in abundance in soil. Maintaining a healthy environment for crops requires a strong link between plants and soil microorganisms that are essential for good crop development. Soil bacteria are key regulators of the nutrient cycle. Mineralization, legume nitrogen fixation, and ammonia conversion to plant-available nitrate would all be impossible without bacteria. Effective microorganisms have the ability to boost crop growth and yield. When used in conjunction with organic amendments, these bacteria performs better than to the sole application. It …

A Review On Overcoming Dual Challenges For Maize Cropping Under High Plant Density: Stalk Lodging And Kernel Abortion, Alam Sher, Javed Iqbal, Wajid Nazeer, Muhammad Mudassar Maqbool, Muhammad Nadeem, Sajid Faiz, Shahbaz Khan
Journal of Bioresource Management
Increased optimal plant density is necessary in ensuring future food security by increasing crop productivity. However, maintaining relatively high plant density has to overcome two challenges i.e. kernel abortion and stalk lodging. The response of maize to increased plant density and the effects of increased plant density on maize productivity were discussed in this research. Increased plant density induces increased plant height, causes low photosynthetic capacity, limits the carbohydrate supply and increases kernel abortion. Also, increased plant density incurs a high risk of stalk lodging due to increased ear height and diminished stem diameter associated with reduced vascular bundles that …

Laurentian Great Lakes Warming Threatens Northern Fruit Belt Refugia, Robert Warren
Biology Faculty Datasets
Climate refugia are anomalous ‘pockets’ of spatially or temporally disjunct environmental conditions that buffer distinct flora and fauna against prevailing climatic conditions. Physiographic landscape features, such as large water bodies, can create these micro-to-macro-scale terrestrial habitats, such as the prevailing westerly winds across the Laurentian Great Lakes that create relatively cooler leeward conditions in spring and relatively warmer leeward conditions in autumn. The leeward Great Lakes climate effects create a refugia (popularly known as a ‘fruit belt’) favorable for fruit-bearing trees and shrubs. This fruit belt refugia owes its existence to seasonal inversions whereby spring cooling prevents early flower budding …

Quantifying Crop Phenology For Food Sustainability Under Climate Change: Integration Of Remote Sensing, Machine Learning, And Ecosystem Modeling, Yanjun Yang
Theses and Dissertations--Plant and Soil Sciences
Climate change is projected to continue and accelerate significantly in the future if global greenhouse gas emissions are not curbed. Previous studies have shown that crop growth and production in agroecosystems are primarily determined by the weather conditions over the growing season. Crop phenology represents one of the most critical indicators in determining crop yield and adjusting the adaptation of crops to climate change. It provides essential information for monitoring and modeling crop growth dynamics and productivity. Therefore, understanding and quantifying the impacts of climate change on crop phenology and then agricultural production is crucial to formulate feasible climatic adaptation …
