The St. Croix East End Marine Park (STXEEMP) was established in 2003 as the first multi-use marine park managed by the U.S. Virgin Islands Department of Planning and Natural Resources. It encompasses an area of approximately 155 km2 and is entirely within Territorial waters which extend up to 3 nautical miles from shore. As stated in the 2002 management plan, the original goals were to: protect and maintain the biological diversity and other natural values of the area; promote sound management practices for sustainable production purposes; protect the natural resource base from being alienated for other land use purposes that would be detrimental to the area’s biological diversity; and to contribute to regional and national development (The Nature Conservancy, 2002). At the time of its establishment, there were substantial data gaps in knowledge about living marine resources in the St. Croix, and existing data were inadequate for establishing baselines from which to measure the future performance of the various management zones within the park. In response to these data gaps, National Centers for Coastal Ocean Science (NCCOS), Center for Coastal Monitoring and Assessment, Biogeography Branch (CCMA-BB) worked with territorial partners to characterize and assess the status of the marine environment in and around the STXEEMP and land-based stressors that affect them. This project collected and analyzed data on the distribution, diversity and landscape condition of marine communities across the STXEEMP. Specifically, this project characterized (1) landscape and adjacent seascape condition relevant to threats to coral reef ecosystem health, and (2) the marine communities within STXEEMP zones to increase local knowledge of resources exposed to different regulations and stressors.

Since 2001, biannual fish and habitat monitoring has been conducted for the shallow (> 30 m), colonized pavement and gorgonian dominated Buck Island Reef National Monument (BIRNM) St. Croix, USVI and adjacent waters. during October, 2005, widespread coral bleaching was observed within the ∼50 square-kilometer study area that was preceded by 10 wks of higher than average water temperatures (28.9–30.1 °C). Random transects (100 square meters) were conducted on linear reefs, patch reefs, bedrock, pavement, and scattered coral/rock habitats during October 2005, and April and October 2006, and species specific bleaching patterns were documented. During October 2005 approximately 51% of live coral cover was bleached. Nineteen of 23 coral species within 16 genera and two hydrocoral species exhibited signs of bleaching. Coral cover for Montastraea annularis and species of the genus Agaricia were the most affected, while other species exhibited variability in their susceptibility to bleaching. Bleaching was evident at all depths (1.5–28 m), was negatively correlated with depth, and positively correlated with habitat complexity. Bleaching was less prevalent at all depths and habitat types upon subsequent monitoring during April (15%) and October (3%) 2006. Four species and one genus did not exhibit signs of bleaching throughout the study period (Dendrogyra cylindrus, Eusmilia fastigata, Mussa angulosa, Mycetophyllia aliciae, Scolymia spp.).

Limited information currently exists on the recovery periods of bleached corals as well as the spatial extent, causative factors, and the overall impact of bleaching on coral reef ecosystems. During October, 2005, widespread coral bleaching was observed within Buck Island Reef National Monument (BUIS) St. Croix, USVI. The bleaching event was preceded by 10 weeks of higher than average water temperatures (28.9-30.1°C). Random transects (100 square meters) over hard bottom habitats (N=94) revealed that approximately 51% of live coral cover was bleached. Nineteen of 23 coral species within 16 genera and two hydrocoral species exhibited signs of bleaching; species-specific bleaching patterns were variable throughout the study area. Coral cover for Montastraea annularisand species of the genus Agariciawere the most affected, while other species exhibited variability to bleaching. Although a weak but significant negative relationship (r2=0.10, P=0.0220) was observed, bleaching was evident at all depths (1.5-28 m). Bleaching was spatially autocorrelated (P=0.001) and hot-spot analysis identified a cluster of high bleaching stations northeast of Buck Island. Bleaching was significantly reduced within all depth zones and habitat types upon subsequent monitoring during April (15%) and October (3%) 2006.

This poster presents information on the status and trends of coral reef ecosystems in St. Croix, US Virgin Islands (USVI). Data were collected by NOAA’s Center for Coastal Monitoring and Assessment Biogeography Branch (CCMA-BB) from 2001-2006 at 1,275 random locations in and around Buck Island Reef National Monument (BIRNM). The main objective was to quantify changes in fish species and assemblage diversity, abundance, biomass and size structure; to provide spatially explicit information on the distribution of key species or groups of species; and to compare community structure inside versus outside of BIRNM.

Ce mémoire étudie l'institution collégiale comme espace de vie au tournant du XXe siècle par le biais d'une étude de cas, le Collège de Sainte-Anne-de-la-Pocatière. Plus concrètement, nous tentons de répondre aux questions suivantes. Comment pense-t-on et aménage-t-on l'espace dans ce collège pour garçons entre 1860-1922? Comment façonne-t-il les identités sociales et que nous révèle-t-il sur celles-ci? Autrement dit, nous nous intéressons aux valeurs qui sont transmises et aux normes sociales qui influencent l'aménagement. Nous cherchons à connaître leur évolution au cours de la période étudiée. Nous soutenons que l'architecture, l'ordonnance spatial, de même que le décor des lieux concourent à inculquer à la jeunesse un système de valeurs qui s'accordent avec l'idéal catholique : le retrait du monde, la piété, le classicisme et le patriotisme sont celles les plus évidemment exhibées au sein du Collège. L'aménagement de l'espace collégial revêt également des fonctions de régulation sociale : il sert à différencier et à hiérarchiser la population collégiale, autant les écoliers, le corps professoral que les employés d'entretien et d'approvisionnement. À un troisième niveau, il apparaît que le Collège de Sainte-Anne se modernise au cours des soixante années examinées. En portant une attention à la sécurité de l'établissement, à l'hygiène corporelle et à l'assainissement des espaces, les nouvelles théories de la pédagogie scolaire à la fin du XIXe siècle, notamment en ce qui concerne les études dites "utilitaires", les sciences, l'exercice physique et les loisirs, affectent et transforment l'institution collégiale de Sainte-Anne. Faire ressortir les effets de l'espace sur la formation identitaire et remettre en cause l'imperméabilité et l'intemporalité de cet espace dit traditionnel constituent donc les premières préoccupations de cette recherche. Le mémoire vise ultimement à mieux comprendre les objectifs d'éducation de l'Église catholique au moment où elle connaît son âge d'or dans la Belle province.
