Abstract:
In 1917, Alfred Mayor surveyed a 270 m transect on a reef flat on American Samoa. Eleven surveys were conducted on the transect from 1917 to 2019. The coral community on the reef crest was resilient over the century, occasionally being seriously damaged but always recovering rapidly. In contrast, the originally most dense coral community on the reef flat has been steadily deteriorating throughout the century. Resilience of coral communities in regions of high wave energy on the reef crests was associated with the important binding function of the crustose coralline alga (CCA) Porolithon onkodes. Successful coral recruits were found on CCA 94% of the time, yet living coral cover correlated negatively with CCA cover as they became alternative winners in competition. Mayor drilled a core from the transect on the surface to the basalt base of the reef 48 m below. Communities on Aua reef were dominated by scleractinians through the Holocene, while cores on another transect 2 km away showed the reef was occupied by alcyonaceans of the genus Sinularia, which built the massive reef with spiculite to the basalt base 37 m below. Despite periods of sea levels rising 9 to 15 times the rate of reef accretion, the reefs never drowned. The consistency of scleractinians on Aua reef and Sinularia on Utulei Reef 2 km away during the Holocene was because the shape of the bay allowed more water motion on Aua reef. After 10700 yr of reef building by octocorals, coastal construction terminated this spiculite-reef development.

Abstract:
Despite being among the most valuable ecosystems on Earth, coral reefs face ongoing threats that could negatively impact the human populations who depend on them. The National Coral Reef Monitoring Program (NCRMP) collects and monitors data on various aspects of U.S. coral reefs to provide a holistic understanding of the status of the reefs and adjacent human communities. This paper explores results from the NCRMP’s first socioeconomic monitoring cycle using an ecosystem services framework and examines how these results can be used to improve coral reef management in the following U.S. coral reef jurisdictions: American Samoa, the Commonwealth of the Northern Mariana Islands, Florida, Guam, Hawai’i, Puerto Rico, and the U.S. Virgin Islands. Results suggest that residents in the U.S. Pacific coral reef basin may hold stronger cultural and provisioning values, whereas residents in the U.S. Atlantic coral reef basin may hold stronger regulating values. These findings suggest that outreach efforts have been successful in communicating benefits provided by coral reef ecosystems to the public. They also provide insight into which ecosystem services are valued in each jurisdiction, allowing resource managers to make science-based decisions about how to communicate conservation and management initiatives.

Abstract:
Ecocolonialism, the imposition of European conservation paradigms and power structures on indigenous villagers, is incompatible with the principles of indigenous control of village rainforest preserves. Since 1988, four rainforest reserves in Western Samoa and one US National Park in American Samoa have been created on communal lands using the principles of indigenous control, preserving a total of 30 000 hectares of lowland rainforest and associated coral reef. The reserves in Western Samoa are owned, controlled, administered and managed by the villagers. While these reserves appear to be robust approaches to preserve establishment within the communal land tenure system of Samoa, the concept of indigenous control appears to conflict with ecocolonialist attitudes that disparage the traditional knowledge, culture, political systems, and integrity of indigenous peoples. We discuss problems that have occurred in the Samoan village preserves and offer suggestions for the establishment of future village-controlled preserves in other areas of the South Pacific.

Abstract:
A recent study reported that seventy-five species of reef-building corals, considered to be at elevated extinction risk when assessed by the criteria of the International Union for Conservation of Nature, occur in Pacific waters under United States jurisdiction. Closer examination substantiates records of occurrence for 66 species, while records for the other 9 species were based on misinterpretations or are otherwise uncertain. Of these, at least 55 have been reported from reef habitat under federal protection within National Parks, Marine National Monuments, National Marine Sanctuaries, and National Wildlife Refuges. The highest number of species (31) is found within the Ofu Island unit of the National Park of American Samoa, followed by Kingman Reef (24) and Palmyra Atoll (21), both within the Pacific Remote Islands Marine National Monument. Federally protected areas already in place serve as important habitats for resources whose stewardship needs and priorities may vary over time.

Abstract:
ABSTRACT Foraminiferal Assemblages on Sediments and Reef Rubble at Conch Reef, Florida USA Christy Stephenson Benthic foraminiferal assemblages are widely used to interpret responses of the benthic communities to environmental stresses. This study compares epibiotic foraminiferal assemblages, collected from reef rubble, with those from reef sediments. The study site, Conch Reef, is the site of the Aquarius Underwater Habitat research facility and includes protected areas used only for scientific studies. Although a number of studies have enumerated foraminiferal taxa from the Florida reef tract, no projects have focused on the assemblages that occur at Conch Reef. Sediment and reef rubbles samples were collected via SCUBA from a depth range of 13 to 26 m during October 2008. Foraminiferal assemblages were assessed and compared between the two sample types. A total of 117 foraminiferal species, representing 72 genera, 37 families, and 8 orders were identified in 13 sediment samples and 21 rubble samples. In the rubble samples, 70 genera were identified, including 12 symbiont-bearing genera representing 20% of the total assemblage, 12 stress-tolerant genera representing 6%, planktic foraminifers representing 1%, and 46 other smaller foraminiferal genera representing 73% of the total foraminiferal assemblage. The rubble samples were quite homogenous. The mean (+SD) Fisher alpha α diversity of genera in these samples was 12.9 + 1.4. Sediment samples included 60 of the same genera. The 12 symbiont-bearing genera represented 41% of the total assemblage, 10 stress-tolerant genera represented 3%, planktic taxa represented 2%, and 40 other smaller foraminiferal genera represented 54% of the total assemblage. Overall, the taxonomic assemblages were very similar between the sample types, with sediment assemblages clearly representing the local and regional reef foraminiferal assemblage. The mean (+SD) Fisher alpha α for sediment samples was 11.4 + 2.3, which is not significantly different from that found for the rubble samples. A concentration ratio comparing relative abundances in sediment vs. rubble samples revealed that shells of larger, symbiont-bearing taxa were about 2.5-5.5 times more concentrated in the sediment, indicating winnowing of smaller taxa. Shells of Siphonatera, an agglutinated miliolid, and Textularia, an agglutinated textularid, were more abundant in sediments than in rubble, indicating high preservation potential. The concentration ratio provides a new taphonomic index that reflects the size and durability of foraminiferal taxa. The mean FORAM Index (FI) for the sediment samples (5.57 + 0.83) indicates that water quality at Conch Reef is suitable for calcifying symbioses. The most abundant symbiont-bearing genera were Amphistegina, Laevipeneroplis, Asterigerina, and Archaias.

Abstract:
Coral reef ecosystems are the most diverse on earth, and their subsistence is being threatened by natural and adverse anthropogenic patterns and processes. In an effort to understand and protect these marine environments, several programs have outlined strategies and initiatives. For example, the United States Coral Reef Task Force���s Mapping and Information Working Group has outlined a specific goal to map all coral reefs below 30 m depth by 2009. This study contributes to achieving that goal for three sites around the island of Tutuila, American Samoa, lying in the heart of the South Pacific. American Samoa, a U.S. territory, is home to the Fagatele Bay National Marine Sanctuary, the smallest and most remote in the United States, and to the National Park of American Samoa. Extensive modern scientific surveys were implemented around the territory in 2001 and have since continued and increased. The presence of protected areas and the existence of scientific data collected with state of the art technology have made the site a priority for the Coral Reef Task Force. In this study, methods for classifying surficial seafloor characteristics as bathymetric position index (BPI) zones and structures were developed and applied to the study sites. BPI zones and structures were classified by using algorithms that combine high-resolution (1 m) multibeam bathymetry and its derivatives: bathymetric position index at multiple scales and slope. The development of algorithms and the classification scheme involved the use of historical and current classification studies and three-dimensional visualization. In addition, the BPI zones and structures were compared to limited biological, geological, and physical attributes recorded during accuracy assessment surveys (photos) and towed diver surveys (video). A rugosity (surface ratio) analysis was added to the study to give a picture of the seafloor roughness. The BPI zone and structure classifications overlap and extend existing classifications from Ikonos satellite imagery for water depths shallower than 30 m. Methods, data and classifications developed and applied in this study will be available to the public as a benthic habitat mapping tool (ArcGIS extension), in an online GIS data archive, and on a compact disc attached to this thesis. They contribute to a broader understanding of the marine and coastal environment and will serve as a baseline of information for benthic habitat mapping and future biological, ecological, and geological surveys. The baseline gives a good indication of characteristics that may indicate areas of high biodiversity. The final maps presented here are especially useful to managers, researchers and scientists that seek to establish and monitor a wider and more effective network of marine and coastal protection.
