Preferences for seafood consumption advice in pregnant American women.

Many women of childbearing age, and pregnant and nursing women in particular, do not consume enough seafood to derive optimal health benefits for themselves and their children. We sought to identify how seafood consumption advice could be designed to encourage pregnant women to eat recommended amounts of seafood. In three focus groups with pregnant or recently pregnant American women, we examined reactions to three aspects of seafood consumption advice. First, we found focus group participants preferred gain-framed statements emphasizing benefits of taking action vs. loss-framed statements emphasizing costs of failing to take action. Many participants indicated the gain-framed statements would encourage them to eat seafood and increase their consumption. Second, we compared responses to a recommendation to eat seafood and a recommendation to eat lower mercury seafood because fear of mercury is a known barrier to seafood consumption by pregnant women. We found no clear preference in our focus groups for either message, suggesting potential value of both messages in communication. Lastly, we examined preferences for systems of categorizing seafood into different consumption categories where the number of categories and the number of species listed in each category varied. We found shorter, dichotomous lists of species to eat and avoid were preferred by some participants for their clarity and ease of use. Longer, more comprehensive lists with additional species and consumption categories (e.g., eat once a week), however, were preferred by many participants because they provided more options and were more likely to be used as a reference. These findings suggest using a layered approach to communication might be helpful by providing short, dichotomous lists of best seafood to eat and seafood to be avoided followed by a link to a longer, more complete list of recommended seafood to be eaten and seafood that should be avoided.

Estimated exposure to mercury from fish consumption among women anglers of childbearing age in the Great Lakes region.

Women of childbearing age (WCBA) are advised by state, tribal, and federal agencies to limit their consumption of certain fish, in part, because of concerns about the ingestion of methylmercury and its impact on the development of fetuses. We studied the fish-eating habits of WCBA who had a fishing license and lived near the Great Lakes, where mercury in locally-caught fish is a concern, as these women were likely at greater risk of elevated mercury exposure than the general population. We used a web-based diary method to gather fish consumption data from WCBA anglers over a 4-month period in the summer of 2014. We estimated mercury intake based on reported mercury content of species consumed, frequency of consumption, and meal portion size, and calculated percent exceeding the USEPA reference dose (RfD). Based on these calculations, we estimated that study participants (n = 1395) ingested 0.031 ±â€¯0.002 (95% CI) ug/kg/d of methylmercury (arithmetic mean). We also found that 3.4% of study participants exceeded the RfD when we averaged estimated intake over the 4-month study period. While most (82%) of the fish meals WCBA anglers ate were purchased fish meals generally low in mercury, study participants ingested a disproportionate amount of mercury from locally-caught fish meals (18% of meals contributed 37% of mercury intake). We estimated 11% of WCBA anglers who did not follow state and federal guidelines in effect at the time of our study exceeded the mercury RfD, whereas fewer than 1% of WCBA anglers who followed the guidelines exceeded the RfD. These findings highlight the importance of encouraging WCBA to follow guidelines from agencies for locally-caught fish, in combination with guidelines for purchased fish.

Effects of a Personal Narrative in Messages Designed to Promote Healthy Fish Consumption Among Women of Childbearing Age.

Women of childbearing age (WCBA) can attain health benefits of fish consumption while minimizing risks by following state and federal fish consumption guidelines, but many women avoid fish out of concerns about mercury exposure. This study tested the impact of brochures, informed by communication theory and research, to promote healthy fish consumption among licensed female anglers. We conducted a randomized, two-wave longitudinal experiment between May 2014 and September 2015 among 1,135 women ages 18-48 years (at baseline), drawn from a sample of licensed anglers in the Great Lakes region of the United States. We randomly assigned women to one of five groups, to either be sent one of four brochures in spring 2015 using a two (including a short personal narrative or not) by two (using certain or uncertain language) factorial design, or to a no-exposure control arm. Participants reported their fish consumption in summer 2014 and summer 2015 via an online diary. Exposure to brochure versions that included a short personal narrative helped move women whose baseline levels of fish consumption were furthest from federal recommendations closer to these guidelines; effects were clearest among women confirmed, by self-report or web tracking, to have seen the brochure. Narratives hold promise as a strategy to communicate effectively about the benefits of healthy fish consumption and risks of overconsumption among WCBA, but widespread dissemination may be necessary to achieve these effects.

Effects of an Advisory Brochure on Fish Consumption of Urban Anglers in the Great Lakes Region.

Past research has suggested that urban anglers are a group at high risk of being exposed to contaminants from fish consumption. Fish consumption advisories have been used in many regions to encourage healthy fish-eating behaviors, but few studies have been designed to assess whether these advisories actually influence behavior as intended. We conducted a large-scale, randomized experiment to test the influence of an advisory brochure on urban anglers' fish consumption. We collected detailed information on anglers' fish consumption in three urban counties in the Great Lakes region in the summers of 2014 and 2015. We provided a treatment group with fish consumption guidelines in an advisory brochure before the summer of 2015 and compared their change in fish consumption to a control group. The brochure led to a reduction in fish consumption for anglers who ate the most fish; these anglers reduced their consumption of high-contaminant purchased fish (by ≥0.2 meals/summer for those in 72nd percentile of fish consumption or above), high-contaminant sport-caught fish (by ≥0.4 meals/summer for those in 87th percentile and above), and low-contaminant sport-caught fish (by ≥0.3 meals/summer by those in 76th percentile and above). The brochure also reduced sport-caught fish consumption among those anglers who exceeded the advisories in 2014 (by 2.0 meals/summer). In addition, the brochure led to small increases in sport-caught fish consumption (0.4-0.6 meals/summer) in urban anglers who ate very little sport-caught fish (≤1 meal/summer).

Using a Web-Based Diary Method to Estimate Risks and Benefits from Fish Consumption.

Accurate estimates of the amount and type of fish people eat are necessary to determine the health benefits and risks of consuming fish, and to assess compliance with fish consumption guidelines issued for fish affected by chemical contaminants. We developed a web-based and mobile-phone-enabled diary methodology to collect detailed fish consumption information for two 16-week periods in the summers of 2014 and 2015. We recruited study participants from two populations living in the Great Lakes region-women of childbearing age (WCBA) and urban residents who had purchased fishing licenses. In this article, we describe the methodology in detail and provide evidence related to participation rates, the representativeness of our sample over time, and both convergent validity and reliability of the data collection methods. Overall, 56% of WCBA and 50% of urban anglers provided complete data across both data collection periods. Among those who provided information at the beginning of Year 2, 97% of both audiences provided information throughout the entire 16-week period. Those who participated throughout the two-year period were slightly older on average (1.9-2.5 years) than other members of our original samples. We conclude that using diaries with web and smartphone technology, combined with incentives and persistent communication, has strong potential for assessing fish consumption in other areas of the country or for situations where the potential risks associated with fish consumption are substantial and the cost can be justified.

The potential impact of aquatic nuisance species on recreational fishing in the Great Lakes and Upper Mississippi and Ohio River Basins.

Concern over the potential transfer of aquatic nuisance species (ANS) between the Great Lakes basin and the Upper Mississippi River basin has motivated calls to re-establish hydrologic separation between the two basins. Accomplishing that goal would require significant expenditures to re-engineer waterways in the Chicago, IL area. These costs should be compared to the potential costs resulting from ANS transfer between the basin, a significant portion of which would be costs to recreational fisheries. In this study, a recreational behavior model is developed for sport anglers in an eight-state region. It models how angler behavior would change in response to potential changes in fishing quality resulting from ANS transfer. The model also calculates the potential loss in net economic value that anglers enjoy from the fishery. The model is estimated based on data on trips taken by anglers (travel cost data) and on angler statements about how they would respond to changes in fishing quality (contingent behavior data). The model shows that the benefit to recreational anglers from re-establishing hydrologic separation exceeds the costs only if the anticipated impacts of ANS transfer on sport fish catch rates are large and widespread.

Local Government Capacity to Respond to Environmental Change: Insights from Towns in New York State.

Local governments attempting to respond to environmental change face an array of challenges. To better understand policy responses and factors influencing local government capacity to respond to environmental change, we studied three environmental issues affecting rural or peri-urban towns in different regions of New York State: climate change in the Adirondacks (n = 63 towns), loss of open space due to residential/commercial development in the Hudson Valley (n = 50), and natural gas development in the Southern Tier (n = 62). Our analysis focused on towns' progression through three key stages of the environmental policy process (issue awareness and salience, common goals and agenda setting, policy development and implementation) and the factors that affect this progression and overall capacity for environmental governance. We found that-when compared to towns addressing open space development and natural gas development-towns confronted with climate change were at a much earlier stage in the policy process and were generally less likely to display the essential resources, social support, and political legitimacy needed for an effective policy response. Social capital cultivated through collaboration and networking was strongly associated with towns' policy response across all regions and could help municipalities overcome omnipresent resource constraints. By comparing and contrasting municipal responses to each issue, this study highlights the processes and factors influencing local government capacity to address a range of environmental changes across diverse management contexts.

How can more women of childbearing age be encouraged to follow fish consumption recommendations?

Several studies show that most women do not consume enough fish during pregnancy (and afterward) to derive the maximum health benefits for themselves and their babies, according to the USDA guidelines. We engaged in a two-part study to better understand what might be done to encourage women of childbearing age to eat healthy fish-a mail survey of women who recently gave birth in Minnesota, Wisconsin, and Pennsylvania, and six focus groups with women of childbearing age living in the Great Lakes region. Similar to other studies, we found that many women changed their behavior and consumed less fish during pregnancy than before. Most women reported receiving information, primarily during pregnancy, about the types of fish and how much fish to eat. As a result, increasing access to information during pregnancy likely would not result in increasing many women's fish consumption. Based on our examination of factors influencing women to try to follow the recommendations, the strongest connection with trying to follow the recommendations was receiving enough information to decide and believing that eating fish was good for the baby. Focus group participants also reported that messages about the specific health benefits of fish consumption for their children were particularly influential. These findings suggest that refining messages through testing might be a valuable approach toward increasing women's consumption of less-contaminated fish.

Anglers as potential vectors of aquatic invasive species: Linking inland water bodies in the Great Lakes region of the US.

Unimpeded transfer and spread of invasive species throughout freshwater systems is of global concern, altering species compositions, disrupting ecosystem processes, and diverting economic resources. The magnitude and complexity of the problem is amplified by the global connectedness of human movements and the multiple modes of inter-basin transport of aquatic invasive species. Our objective was to trace the fishing behavior of anglers delineating potential pathways of transfer of invasive species throughout the vast inland waters of the Great Lakes of North America, which contain more than 21% of the world's surface freshwater and are among the most highly invaded aquatic ecosystems in the world. Combining a comprehensive survey and a spatial analysis of the movements of thousands of anglers in 12 states within the US portion of the Great Lakes Basin and the Upper Mississippi and Ohio River Basins, we estimated that 6.5 million licensed anglers in the study area embarked on an average of 30 fishing trips over the course of the year, and 70% of the individuals fished in more than one county. Geospatial linkages showed direct connections made by individuals traveling between 99% of the 894 counties where fishing occurred, and between 61 of the 66 sub-watersheds in a year. Estimated numbers of fishing trips to individual counties ranged from 1199-1.95 million; generally highest in counties bordering the Great Lakes. Of these, 79 had more than 10,000 estimated fishing trips originating from anglers living in other counties. Although angler movements are one mechanism of invasive species transfer, there likely is a high cumulative probability of invasive species transport by several million people fishing each year throughout this extensive freshwater network. A comprehensive georeferenced survey, coupled with a spatial analysis of fishing destinations, provides a potentially powerful tool to track, predict, curtail and control the transfer and proliferation of invasive species in freshwater.

Linking knowledge to action in collaborative conservation.

Authors have documented a "research-implementation gap" in conservation. Research intended to inform conservation practice often does not, and practice often is not informed by the best science. We used the literature on policy learning (i.e., literature attributing policy change to learning) to structure a study of how practice is informed by science in collaborative conservation. We studied implementation by U.S. states of state wildlife action plans. On the basis of 60 interviews with government and nongovernmental organization representatives, we identified 144 implementation initiatives for State Wildlife Action Plans that were collaborative. We conducted case studies of 6 of these initiatives, which included interviews of key individuals and analysis of written documents. We coded interview transcripts and written documents to identify factors that influence availability and use of scientific information. We integrated these factors into a model of collaborative conservation. Although tangible factors such as funding and labor directly affected the availability of scientific information, practitioners' ability and willingness to use the information depended on less tangible factors such as the quality of interpersonal relationships and dialogue. Our work demonstrates empirically that relationships and dialogue led to: (1) the sharing of resources, such as funding and labor, that were needed to carry out research and produce information and (2) agreement among researchers and practitioners on conservation objectives, which was necessary for that new information to inform action. Our findings can be understood in the context of broader concepts articulated in the policy-learning literature, which establishes that social learning (improving relationships and dialogue) provides the foundation for conceptual learning (setting objectives) and technical learning (determining how to achieve these objectives).

Resumen: Diferentes autores han documentado un "vacío de investigación-implementación" en la conservación. La investigación que intenta informar a la práctica de la conservación a menudo no lo hace, y la práctica a menudo no es informada por la mejor ciencia. Utilizamos la literatura sobre aprendizaje de políticas (i.e., literatura que atribuye cambios en políticas al aprendizaje) para estructurar un estudio de cómo la práctica es informada por la ciencia en conservación colaborativa. Estudiamos la implementación de planes de acción para vida silvestre en estados de E.U.A. Con base en 60 entrevistas con representantes de organizaciones gubernamentales y no gubernamentales, identificamos 144 iniciativas de implementación de Planes de Acción Estatales para Vida Silvestre que fueron colaborativas. Realizamos estudios de caso de 6 de estas iniciativas, que incluían entrevistas a individuos clave y el análisis de documentos escritos. Codificamos las transcripciones de las entrevistas y los documentos escritos para identificar factores que influyen en la variabilidad y uso de la información científica. Integramos estos factores en un modelo de investigación colaborativa. Aunque factores tangibles, como el financiamiento y labor, directamente afectaron la disponibilidad de información científica, la habilidad y disponibilidad de practicantes para utilizar la información dependió de factores menos tangible como la calidad de relaciones interpersonales y de diálogo. Nuestro trabajo demuestra empíricamente que las relaciones y el diálogo llevaron a: (1) compartir recursos, como el financiamiento y la labor, que fueron necesarios para llevar a cabo el proyecto y producir información y (2) acuerdos sobre objetivos de conservación entre investigadores y practicantes, lo cual fue necesario para que la información nueva informe a la acción. Nuestros hallazgos pueden ser entendidos en el contexto de conceptos más amplios articulados en la literatura de aprendizaje de políticas, que establece que el aprendizaje social (mejora de relaciones y diálogo) proporciona el fundamento del aprendizaje conceptual (fijar objetivos) y el aprendizaje técnico (determinación de cómo alcanzar esos objetivos).

Social networks and community-based natural resource management.

We conducted case studies of three successful examples of collaborative, community-based natural resource conservation and development. Our purpose was to: (1) identify the functions served by interactions within the social networks of involved stakeholders; (2) describe key structural properties of these social networks; and (3) determine how these structural properties varied when the networks were serving different functions. The case studies relied on semi-structured, in-depth interviews of 8 to 11 key stakeholders at each site who had played a significant role in the collaborative projects. Interview questions focused on the roles played by key stakeholders and the functions of interactions between them. Interactions allowed the exchange of ideas, provided access to funding, and enabled some stakeholders to influence others. The exchange of ideas involved the largest number of stakeholders, the highest percentage of local stakeholders, and the highest density of interactions. Our findings demonstrated the value of tailoring strategies for involving stakeholders to meet different needs during a collaborative, community-based natural resource management project. Widespread involvement of local stakeholders may be most appropriate when ideas for a project are being developed. During efforts to exert influence to secure project approvals or funding, however, involving specific individuals with political connections or influence on possible sources of funds may be critical. Our findings are consistent with past work that has postulated that social networks may require specific characteristics to meet different needs in community-based environmental management.
