Comparing Mortality In Response To Simulated Climate Change In The Harvester Ant, Pogonomyrmex Badius, And The Fire Ant, Solenopsis Invicta, Haley Depner

USF Tampa Graduate Theses and Dissertations

With the rapid transport of plants, produce, and goods out of its South American home, the fire ant, Solenopsis invicta, has invaded continents on a global scale. In the United States alone, S. invicta is responsible for an estimated $1 billion in damages annually. In contrast to the invasive fire ant, Florida’s native harvester ant, Pogonomyrmex badius, is a keystone seed disperser, providing seed relocation benefits to Florida’s sandhill wildfire-adapted habitats. Seed relocation reduces seedling competition for nutrients with the parent plant, reduces predation of seeds by rodents, increases nutrient loads associated with ant mound soils, and protects seeds from …

Weather Factors Influencing Winter Roosts Of American Crows In Central Iowa, Joshua D. Obrecht, Stephen J. Dinsmore

Journal of the Iowa Academy of Science: JIAS

We investigated the effects of season and weather on the winter roosting behavior of American Crows (Corvus brachyrhynchos) in central Iowa from January through March 2006. The peak number of birds recorded at a roost in Ames, Story County was 9,000+ in early February, and the number of individuals entering the roost decreased through February and March. Crows tended to enter the roost later in the day as winter neared completion. High wind speed and low light intensity caused individual to enter the roost earlier in the day. Temperature did not affect arrival time of crows. Wind speed, light intensity, …

Nf03-571 Aspergillus Flavus And Aflatoxins In Corn, Jim Stack, Michael Carlson

University of Nebraska-Lincoln Extension: Historical Materials

The severe weather conditions of the 2002 growing season resulted in an increase in the incidence and severity of aflatoxin contamination of both food grade and feed grade corn in Nebraska.

The mycotoxin called aflatoxin is produced by the grain mold Aspergillus flavus. Not all isolates of A. flavus produced aflatoxin and isolates that are capable of producing aflatoxin do not always synthesize the toxin. Many factors including environmental conditions and host suscepbitility, determine the incidence and severity of grain mold and subsequent mycotoxin contamination.

This NebFact discusses the cause and occurrence of aflatoxin in corn; the effects it has …

Ec98-278 Grazing Crop Residues, Richard J. Rasby, Roger Selley, Terry Klopfenstein

University of Nebraska-Lincoln Extension: Historical Materials

Nebraska has an abundance of crop residue available for late fall and winter grazing. However, several factors prevent the grazing of many fields, including the location of fields in relation to the cattle, the lack of shelter or appropriate fencing and water availability. Despite these limitations, residue grazing is an important resource to many cattle operations, primarily as either a winter feed resource for maintaining the breeding herd or putting weight on cull cows. Calves weaned in the fall can also be wintered on cornstalks if appropriate supplementation is used.

Nf95-218 Conjunctive Use Policy Options, William Miller

University of Nebraska-Lincoln Extension: Historical Materials

Background

The hydrologic cycle controls water available for use. Rainfall, evaporation, runoff, percolation, and transpiration combine to influence the water available at a specific location at a particular point in time. The speed at which water moves among stages in the hydrologic cycle and the amount of time it spends in storage at any stage affects water availability to users. The conjunctive use issue refers to the portion of the hydrologic cycle where groundwater and surface water interface and influence each other.

Users who couldn't depend on an irregular flow of water over time developed systems that modify the variable …

Ec94-132 Freeze Injury To Nebraska Wheat, Robert N. Klein, Drew J. Lyon, John E. Watkins

University of Nebraska-Lincoln Extension: Historical Materials

Nebraska’s adverse weather conditions affect winter wheat during much of its growth. The newer varieties of wheat have increased winter hardiness, and better management practices have reduced winter injury of winter wheat, yet low temperature injury during winter and spring can be destructive. Wheat has little resistance to low temperatures after it begins growing in the spring; therefore, injury from freezes at this time can occur in any part of the state. This publication describes temperature conditions that cause winter injury, symptoms of injury at different spring growth stages, and management practices to use when wheat is injured.

Ec89-119 Hail Damage Assessment And Replant Decisions, Charles A. Shapiro, Timothy A. Powell

University of Nebraska-Lincoln Extension: Historical Materials

Hail is one of the many hazards that can damage a growing crop. Early in the growing season a producer has the option to replant a field seriously damaged by hail. The question is, how do you decide if it is worthwhile to replant, and what information do you need to make an informed decision? Factors to consider when deciding to replant are the expected yield reduction due to hail, the cost of replanting, and the yield potential of the replanted crop. Other information needed to make a rational decision is included in this publication, and several examples are given.

The rate of growth increases with temperature above this base.

Crop hybrids require different GDD accumulations to reach maturity.

G81-552 Effects Of Weather On Corn Planting And Seedling Establishment, Ralph E. Neild

University of Nebraska-Lincoln Extension: Historical Materials

Corn planting usually begins when the average daily temperature first rises 55°F and the soil becomes sufficiently warm enough to initiate germination and sustain seedling growth. This may be as early as the middle of March in central Texas 700 miles south of Nebraska or as late as the middle of May in central South Dakota. Corn may be planted as early as the first week of April in southeast Nebraska and continue into the first week of June. Most of the corn, however, is planted between May 4 and May 21.

Corn planted early when the temperature is cool …
