Toward the development of microbial indicators for wetland assessment.

Wetland assessment tools are being developed and employed in wetland monitoring and conservation based on physical, chemical and biological characterization. In wetland biological assessment, various ecological functions have been described by biological traits of an entire species pool that adapts to different types of wetland environments. Since microorganisms play a key role in wetland biogeochemical processes and respond quickly to environmental disturbances, this review paper describes the different macro indicators used in wetland biological monitoring and expands the potential use of microbial indicators in wetland assessment and management. Application of molecular microbial technologies paves the path to an integrated measure of wetland health conditions. For example, the ratio of ammonia-oxidizing archaeal and bacterial populations has been proposed to serve as a microbial indicator of wetland nutrient conditions. The microbial indicators coupled with physical, chemical and other biological parameters are vital to the development of multi-metric index for measuring wetland health conditions. Inclusion of microbial indicators will lead to a more comprehensive wetland assessment for wetland restoration and management practices.

Perspectives on Latino lay health promoter programs: Maryland, 2009.

OBJECTIVES: We examined common barriers and best practices in the design, implementation, monitoring, and evaluation of Latino lay health promoter programs. METHODS: Ten lay health promoter program coordinators serving Maryland Latinos were recruited in 2009 through snowball sampling for in-depth semistructured interviews with a bilingual and bicultural researcher. Program coordinators were asked about recruitment, selection, training, and supervision; key program elements; and evaluation. Analyses were conducted to identify common themes. RESULTS: Respondents had worked up to 13 years in programs focused on such areas as awareness of healthy lifestyles and reducing risk of illness. Coordinators looked for Latino leaders with team-building skills and a desire to help the community. Six programs compensated promoters with stipends; 4 paid an hourly wage. Promoters were usually trained in monthly meetings that actively engaged them. Most programs conducted site visits, practice sessions, and performance evaluations. CONCLUSIONS: Our findings indicate that successful health promoter programs require needs assessments, formation of a target population advisory board, identification of appropriate promoters, and a significant amount of training. These findings can be used to guide future programs in the identification, recruitment, and training of health promoters as well as in program monitoring.
