Lingering Impacts of Hurricane Hugo on Rhizophora mangle (Red Mangrove) Population Genetics on St. John, USVI

Stochastic events can have catastrophic effects on island populations through a series of genetic stressors from reduced population size. We investigated five populations of red mangrove (Rhizophora mangle) from St. John, USVI, an UNESCO Biosphere Reserve, which were impacted by Hurricane Hugo in 1989. Our goal was to determine diversity and to ascertain potential population bottlenecks two decades after the event. With the lowest observed heterozygosity, highest inbreeding coefficient, and evidence of a major bottleneck, our results demonstrated that the Great Lameshur mangroves, devastated by Hurricane Hugo, were the least diverse stand of trees. The other four populations from St. John manifested diversity reflecting the vegetation patterns of “fringing” mangrove or “developed forest” characteristics. The two fringing mangrove populations (Hurricane Hole and New Found Bay) evinced low observed heterozygosity and high inbreeding coefficients, while the fully forested sites showed higher heterozygosity and lower inbreeding frequencies. As such, fringing mangroves may be at greater risk to disturbance events and especially susceptible to sea level rise since they do not have room landward to expand. Our pair-wise population analysis indicated genetic similarity between the hurricane-damaged Great Lameshur and Coral Bay population, whose propagules were used in previous restoration attempts and is the geographically closest population. While the effective population size for Great Lameshur Bay places it in risk of genetic dysfunction, future rehabilitation of the site may be possible by the introduction of propagules from other regions of the island. However, recovery will ultimately be contingent upon hydrological connectivity and environmental improvements.

Architextual Authenticity

Construction of identity has constituted a vigorous source of debate in the Caribbean from the early days of colonization to the present, and under the varying guises of independence, departmentalization, dictatorship, overseas collectivity and occupation. Given the strictures and structures of colonialism long imposed upon the colonized subject, the (re)makings of identity have proven anything but evident when it comes to determining authentic expressions and perceptions of the postcolonial self. By way of close readings of both constructions in literature and the construction of literature, Architextual Authenticity: Constructing Literature and Literary Identity in the French Caribbean proposes an original, informative frame of reference for understanding the long and ever-evolving struggle for social, cultural, historical and political autonomy in the region. Taking as its point of focus diverse canonical and lesser-known texts from Guadeloupe, Martinique and Haiti published between 1958 and 2013, this book examines the trope of the house (architecture) and the meta-textual construction of texts (architexture) as a means of conceptualizing and articulating how authentic means of expression are and have been created in French-Caribbean literature over the greater part of the past half-century—whether it be in the context of the years leading up to or following the departmentalization of France’s overseas colonies in the 1940’s, the wrath of Hurricane Hugo in 1989, or the devastating Haiti earthquake of 2010.

Probabilistic hurricane-induced storm surge hazard assessment in Guadeloupe, Lesser Antilles

Current storm surge hazard maps in the French West Indies are essentially based on simple statistical methods using limited historical data and early low-resolution models which do not take the effect of waves into account. In this paper, we infer new 100-year and 1000-year surge levels in Guadeloupe from the numerical modelling of storm surges induced by a large set of synthetic events that are in statistical agreement with features of historical hurricanes in the North Atlantic Basin between 1980 and 2011. Computations are performed using the wave-current coupled model ADCIRC–SWAN with high grid resolutions (up to 40–60 m) in the coastal and wave dissipation areas. This model is validated against observations during past events such as hurricane HUGO (1989). Results are generally found to be in reasonable agreement with past studies in areas where surge is essentially wind-driven, but found to differ significantly in coastal regions where the transfer of momentum from waves to the water column constitutes a non-negligible part of the total surge. The methodology, which can be applied to other islands in the Lesser Antilles, allows storm surge level maps to be obtained that can be of major interest for coastal planners and decision makers in terms of risk management.

Coordinated management of coastal hazard awareness and preparedness in the USVI

As far back as history has been written in the islands today known as the US Virgin Islands (USVI), residents have had to endure and survive costly and deadly onslaughts from tropical storms such as the 1867 San Narciso Hurricane, Hurricane Hugo and Hurricane Marilyn. Keenly alerted by recent tragic events in the Indian Ocean in 2004, in Haiti in 2010 and in Japan in 2011, the USVI was reminded that it had suffered its greatest tsunami impact in a well-documented event that had followed the 1867 hurricane by fewer than three weeks. To address their community's continual vulnerability to coastal hazards, USVI emergency managers, scientists and educators, assisted by national and regional disaster management agencies and warning programs, have engaged programs for understanding, anticipating and mitigating these hazards. This paper focuses on how three public-serving institutions, the Virgin Islands Territorial Emergency Management Agency (VITEMA), the University of the Virgin Islands and the Caribbean Ocean Observing System have responded to the community's need for improved preparedness through programs of physical preparation, planning, research, observations, education and outreach. This report reviews some of the approaches and activities employed in the USVI in the hope of sharing their benefits with similarly vulnerable coastal communities.

Marriage following the 1997 Umbria-Marche (Italy) earthquake

Purpose – The purpose of this paper is to replicate Cohan and Cole (2002) Hurricane Hugo study in the context of a different type of natural hazard and in a different country. Design/methodology/approach – Change in marriage following the 1997 Umbria-Marche (Italy) earthquake was examined prospectively from 1987 to 2007 for the 15 municipalities declared disaster areas and for the whole Marche region and country. Findings – Autoregressive integrated moving average time-series analysis showed that the year following the earthquake marriage rates decreased only in the 15 municipalities declared disaster areas. Originality/value – In the present study, the paper found results in the opposite direction to Cohan and Cole (2002) Hurricane Hugo study. Taken together, the findings suggest that the direction of the change may be in either direction and depends on the characteristics of the disaster, of the response to it, and on social and economic conditions of the context.
