The purpose of this research is to determine the validity of the subjective, anecdotal rule that four isobars present across Iowa during a wintertime, snow-bearing, extratropical cyclone is sufficient to create the winds that attend a blizzard (the “Four Isobar Rule”). Using data from the National Centers for Environmental Information's online Storm Event Database, we identified 15 cases of blizzards in Iowa over the course of 10 years (1999-2009 plus one event in 2010). Subjective analyses of mean sea level pressure for those 15 events revealed an 87% success rate of having four isobars present corresponding with the Blizzard events. Conversely, we also analyzed 23 Near-Blizzard events and discovered that approximately 74% did not have four isobars present. Clearly, there is overlap between these types of events. Composite meteorological fields of both case sets were completed using the North America Regional Reanalysis datasets. The composite results are generally consistent with other recent findings on Iowa blizzards. The surface low is often fairly deep (<1000 hPa), occluded or nearly so, featuring a convergent, descending lower troposphere, with 850-hPa winds of 45 kt or greater, and a near-surface layer whose lapse rate is nearly dry adiabatic. The composites of storms in the Blizzard category are slightly weaker than in prior literature, but the composites of storms in the Near-Blizzard category fail to meet any of the criteria for a blizzard in the state of Iowa.

Territoriality plays a key role in the survival and reproduction of many species. Damselfish (Family: Pomacentridae), reef-dwelling fish found in tropical locations, are territorial and competitively engage both intra- and inter-specific fish in order to protect their algal lawns. While damselfish territoriality has been examined as it relates to attack distance in con- and hetero-specifics, aggression in damselfish has not yet been related to fish density and proximity. The Galápagos yellowtail damselfish, Stegastes arcifrons, was selected for analysis of the factors that affect its behavioral aggression. Yellowtail damselfish individuals (n=31) were observed in the wild in 5-minute counts for aggressive interactions toward con- and hetero-specifics. The average location of the observed damselfish, including the locations of its nearby neighbors, was noted and dive markers were placed at these locations following the 5-minute count. Photographs of the average locations of the damselfish during the test, as shown by the dive markers, were taken and imaging software was used to determine damselfish density and an approximation of controlled territory through conversion into Voronoi diagrams. Aggression rates toward conspecific encounters, measured in aggressive attacks/minute, were positively correlated with damselfish density and inversely correlated with controlled territory size (p < 0.001 for both correlations, R2 = 0.52 and 0.35 respectively). There were no significant correlations between aggression rates toward heterospecific encounters and any measured variables (p > 0.05 for all correlations). The number of nearby neighbors was also not significantly correlated with aggression (p > 0.05). Damselfish aggression is a direct function of both controlled area and conspecific density, but not of the number of nearby neighbors nor heterospecific individuals.

Bacillus subtilis is capable of swarming motility on semisolid surfaces. Here we characterize the swarming phenotype of a mutant in the gene of unknown function, yozG in the undomesticated strain 3610. The yozG mutant was unable to swarm. Swarming could be restored to the mutant by overexpression of the swarming regulator gene swrA or by overexpression of the flagella and chemotaxis operon. In addition, we were able to isolate two genetic suppressors of the yozG mutant that could also restore swarming. yozG is necessary for swarming in B. subtilis and likely acts upstream of the swarming regulator, SwrA.

The widespread decline in amphibian populations highlights the need for establishing rigorous monitoring methods for long-term population studies. In an attempt to launch a long-term monitoring study for a Gray Treefrog complex (Hyla versicolor LeConte /chrysoscelis Cope, hereafter treefrog) population in northwest Missouri, I tested the use of PVC pipe traps in a system of ponds and inlets along a lakeside habitat for three years. For each pond (3) and inlet (2), I established an array of 16 pipes so as to compare differences in use between pipe location, ponds and inlets, and sex ratio between sites. Pipes were checked twice a week during the summer for the presence of treefrogs. Treefrog usage of pipes between ponds and inlets were compared using a contingency table analysis, while an ANOVA was used to assess differences in sex ratios between sites (α = 0.05). A single inlet was used by treefrogs more heavily than the other ponds or inlet (G = 13.61, df = 3, P = 0.0035), however, I found no differences in terms of pipe location within a pond or inlet. Mean sex ratio between water bodies varied but did not significantly differ. There appears to be little effect in terms of pipe placement within our 50 m buffer from the water's edge, but unique habitat effects at sampling locations may significantly affect detection rates or usage.

Semen used for artificial insemination (AI) in the swine industry is typically collected into a warmed semen collection cup containing an empty collection bag. If the ambient temperature does not closely match the temperature of the warmed collection cup and semen at the time of collection then negative effects to the motility and morphology of the sperm cells may occur due to temperature shock. The purpose of this research was to determine if collecting boar semen directly into semen extender warmed to 38.5°C would affect sperm quality post-collection. Sexually mature Berkshire x Duroc crossbred boars (n = 7) were semen collected once per week for four consecutive weeks. Every other collection, the boar's ejaculate was collected into a collection cup and plastic collection bag warmed to 38.5°C containing either no semen extender (control) or 100 mLs of a commercially available long-term semen extender warmed to 38.5°C (treatment). Following collection and processing, the semen was extended to 37.5 × 106 sperm/mL and stored for 6 days post-collection in a semen cooler at 17°C. Motility and morphology were evaluated on day 0 (day of collection) and day 6. There was no day x treatment effect (P > 0.05). Statistical differences (P = 0.03) were found between the treatment and control for sperm motility (82.2 vs. 75.2%) and sperm progressive motility (64.1 vs. 53.5%). No differences (P = 0.96) were present for normal sperm morphology in the treatment compared to the control (89.1 vs. 89.0%). These data suggest that boar semen ejaculates collected into a collection cup and plastic collection bag containing 100 mLs of semen extender warmed to 38.5°C will have greater percentages of motile and progressively motile sperm compared to boar sperm collected into a collection cup and plastic collection bag warmed to 38.5°C containing no semen extender.
在养猪业中用于人工授精(AI)的精液通常被收集到一个装有空收集袋的温暖的精液收集杯中。如果环境温度与收集时加热的收集杯和精液的温度不密切匹配，那么由于温度冲击，可能会对精子细胞的活力和形态产生负面影响。本研究的目的是确定将猪精液直接收集到加热至38.5°C的精液扩展器中是否会影响收集后的精子质量。7头性成熟的伯克夏×杜洛克杂交公猪每周采集一次精液，连续采集4周。每隔一次采集，将公猪的精液收集到加热到38.5°C的收集杯和塑料收集袋中，其中要么不含精液扩展剂(对照组)，要么含有100毫升加热到38.5°C的市售长期精液扩展剂(治疗组)。收集和处理后，将精液延长至37.5 × 106个/mL，在精液冷却器中保存6天，温度为17°C。分别于第0天(采集日)和第6天进行运动和形态学评价。无x天治疗效果(P > 0.05)。治疗组与对照组精子活力(82.2 vs. 75.2%)和精子进行性活力(64.1 vs. 53.5%)差异有统计学意义(P = 0.03)。与对照组相比，治疗组正常精子形态无差异(P = 0.96)(89.1比89.0%)。这些数据表明，与加热到38.5°C不含精液扩展剂的收集杯和塑料收集袋中收集的猪精液相比，将含有100毫升精液扩展剂的收集杯和塑料收集袋中收集的猪精液具有更高的运动和逐渐运动的精子百分比。
