Perceived Adaptive Capacity and Natural Disasters: A Fisheries Case Study

Fishermen may be increasingly impacted by natural disasters, given sea level rise and the likely increased frequency and severity of storms associated with climate change. Planning for resiliency in the face of these disasters requires understanding the factors that influence fishermen’s capacity to adapt. The paper examines perceptions of adaptive capacity of New York and New Jersey commercial and for-hire fishermen one year after Hurricane Sandy. Subjective adaptive capacity to changes in the fishery in general and those caused by natural disasters was assessed. A comparison between commercial and for-hire fishermen revealed important differences and similarities with regard to attributes influencing their perceived adaptive capacity. While both groups show high levels of coping capacity in general, for-hire fishermen presented more confidence in their ability to obtain work and income outside the fishery while commercial fishermen were more confident in their ability to remain in fishing. For both groups, those that suffered more intense impacts from the storm had more negative levels of perceived adaptive capacity. Understanding the perceived adaptive capacity of commercial and for-hire fishermen can help researchers and policy makers better understand and address each sector’s response to impacts of future natural disasters and human driven changes

Social Bonds and Recovery: An Analysis of Hurricane Sandy in the First Year after Landfall

Hurricane Sandy was one of the most devastating hurricanes to hit US shores. The brunt of the impact was felt in New York and New Jersey, especially among coastal towns such as fishing communities. A survey of these two states assessed social and economic impacts to 958 commercial and recreational fishermen and fishing-related business owners 12 months post-storm. Many businesses and communities were still struggling, due to heavy infrastructure damages and revenue losses with low insurance coverage, but also to disrupted fishing patterns for some species. Social bonds were credited by many as a key aid to recovery. Social bonds (sometimes called bonding social capital) have been shown to be critical for evacuation and recovery in other disasters. However, few studies examine social bonds and disasters within the context of fisheries. This paper expands upon that topic

Toward a Model for Fisheries Social Impact Assessment

This paper presents a model for Fisheries Social Impact Assessment (SIA) that lays the groundwork for development of fisheries-focused, quantitative social assessments with a clear conceptual model. The usefulness of current fisheries SIA’s has been called into question by some as incompatible with approaches taken by fisheries biologists and economists when assessing potential effects of management actions. Our model’s approach is closer to the economists’ and biologists’ assessments and is therefore more useful for Fishery Management Council members. The paper was developed by anthropologists initially brought together in 2004 for an SIA Modeling Workshop by the National Marine Fisheries Service, NOAA. Opinions and conclusions expressed or implied are solely those of the authors and do not necessarily reflect the views or policy of the National Marine Fisheries Service, NOAA

The global oscillation network group site survey. II. Results

The Global Oscillation Network Group (GONG) Project will place a network of instruments around the world to observe solar oscillations as continuously as possible for three years. The Project has now chosen the six network sites based on analysis of survey data from fifteen sites around the world. The chosen sites are: Big Bear Solar Observatory, California; Mauna Loa Solar Observatory, Hawaii; Learmonth Solar Observatory, Australia; Udaipur Solar Observatory, India; Observatorio del Teide, Tenerife; and Cerro Tololo Interamerican Observatory, Chile. Total solar intensity at each site yields information on local cloud cover, extinction coefficient, and transparency fluctuations. In addition, the performance of 192 reasonable components analysis. An accompanying paper describes the analysis methods in detail; here we present the results of both the network and individual site analyses. The selected network has a duty cycle of 93.3%, in good agreement with numerical simulations. The power spectrum of the network observing window shows a first diurnal sidelobe height of 3 × 10⁻⁴ with respect to the central component, an improvement of a factor of 1300 over a single site. The background level of the network spectrum is lower by a factor of 50 compared to a single-site spectrum

Tricks and treats: designing technology to support mobility assistance dogs

Assistance dogs are a key intervention to support the autonomy of people with tetraplegia. Previous research on assistive technologies have investigated ways to, ultimately, replace their labour using technology, for instance through the design of smart home environments. However, both the disability studies literature and our interviews suggest there is an immediate need to support these relationships, both in terms of training and bonding. Through a case study of an accessible dog treats dispenser, we investigate a technological intervention responding to these needs, detailing an appropriate design methodology and contributing insights into user requirements and preferences

Light Converts Endosymbiotic Fungus to Pathogen, Influencing Seedling Survival and Niche-Space Filling of a Common Tropical Tree, Iriartea deltoidea

Pathogens are hypothesized to play an important role in the maintenance of tropical forest plant species richness. Notably, species richness may be promoted by incomplete filling of niche space due interactions of host populations with their pathogens. A potentially important group of pathogens are endophytic fungi, which asymptomatically colonize plants and are diverse and abundant in tropical ecosystems. Endophytes may alter competitive abilities of host individuals and improve host fitness under stress, but may also become pathogenic. Little is known of the impacts of endophytes on niche-space filling of their hosts
