Influence of Deer Damage on Farmers\u27 Perceptions of Deer Population Trends: Important Implications for Managers

Farmers\u27 attitudes toward deer, their perceptions of deer depredations and their preferences for future deer population levels have been extensively studied in New York (Brown and Decker 1979; Brown et al. 1977a,1977b, 1978a,1978b, 1979,1980; Decker and Brown 1982; Decker et al. 1981a, 1981b). These studies have contributed to deer-population-management decisions that give consideration to farming interests. Nevertheless, farmers cannot be expected to support deer management efforts on their behalf if they do not understand the population changes such management is designed to achieve. Consequently, wildlife managers need to know whether or not the effects of such efforts are recognized. A direct indication of this, which had not been examined previously, is how well the farming community perceives changes in deer abundance over a reasonable period of time, say 5 years. Using data from the previous studies cited and a deer-population index, the authors sought an answer to the following question: Do farmers recognize managed increases or decreases in deer populations, or do they simply react to experience with deer damage

Microbial Community Dynamics of Lactate Enriched Hanford Groundwaters

The Department of Energy site at Hanford, WA, has been historically impacted by U and Cr from the nuclear weapons industry. In an attempt to stimulate microbial remediation of these metals, in-situ lactate enrichment experiments are ongoing. In order to bridge the gap from the laboratory to the field, we inoculated triplicate anaerobic, continuous-flow glass reactors with groundwater collected from well Hanford 100-H in order to obtain a stable, enriched community while selecting for metal-reducing bacteria. Each reactor was fed from a single carboy containing defined media with 30 mM lactate at a rate of 0.223 ml/min under continuous nitrogen flow at 9 ml/min. Cell counts, organic acids, gDNA (for qPCR and pyrosequencing) and gases were sampled during the experiment. Cell counts remained low (less than 1x107 cells/ml) during the first two weeks of the experiment, but by day 20, had reached a density greater than 1x108 cells/ml. Metabolite analysis showed a decrease in the lactate concentrations over time. Pyruvate concentrations ranged from 20-40 uM the first week of the experiment then was undetectable after day 10. Likewise, formate appeared in the reactors during the first week with concentrations of 1.48-1.65 mM at day 7 then the concentrations decreased to 0.69-0.95 on day 10 and were undetectable on day 15. Acetate was present in low amounts on day 3 (0.15-0.33 mM) and steadily increased to 3.35-5.22 mM over time. Similarly, carbon dioxide was present in low concentrations early on and increased to 0.28-0.35 mM as the experiment progressed. We also were able to detect low amounts of methane (10-20 uM) during the first week of the experiment, but by day 10 the methane was undetectable. From these results and pyrosequencing analysis, we conclude that a shift in the microbial community dynamics occurred over time to eventually form a stable and enriched microbial community. Comprehensive investigations such as these allow for the examination of not only which nutrient source will accelerate site remediation, but also provide insight to evaluate remediation strategies through which enriched community members are important for bioremediation
