    Satellite monitoring of coastal marine ecosystems: a case from the Dominican Republic

    Este reporte se ocupa de los cambios globales en los ecosistemas marinos de la costa, especialmente los que están ocurriendo en la Isla Española. Los arrecifes de coral de la Española, como cualquier otro ecosistema marino costero alrededor del planeta, están siendo acosados por actividades humanas, están siendo degradados, y están enfrentando su destrucción. Cuando los arrecifes de coral mueren, sus superficies se tornan blancas. Esto produce un fenómeno visual denominado blanqueamiento de los arrecifes de coral. Aunque la causa del blanqueamiento del coral no es aún bien conocida, parece ser una respuesta a presiones provenientes ya sea de altas o bien de bajas temperaturas del agua, de altos influjos de radiaciones visibles y ultravioletas, de prolongada exposición aérea, de disolución de agua dulce, de alta sedimentación, de contaminación orgánica debida al exceso de nutrientes de plantas y fertilizantes que se deslavan de las tierras, y de otros tipos de contaminación. Concomitantemente, los seres humanos usan los recursos naturales de esos ecosistemas y sus actividades pueden causar efectos profundos. Los efectos de las actividades humanas no han sido bien entendidos aún, ni tampoco se han documentado sistemáticamente sus efectos a largo plazo. Es el propósito de esta investigación el documentar cómo y porqué estos cambios están teniendo lugar a lo largo de una parte de la costa norte de la República Dominicana, de tal manera que podamos entender mejor como documentar tales cambios en cualquier otra parte del planeta. Esta investigación busca además entender como los seres humanos pueden convertirse en parte de la solución aun siendo parte del mismo problema, proporcionando así una perspectiva equilibrada de las dimensiones humanas del cambio global

    Cultural Basis of Sport Anglersˈ Response to Reduced Lake Trout Catch Limits

    The cultural domain of southeastern Wisconsin anglers along Lake Michigan was assessed from responses to a state‐proposed reduction in the daily allowable catch of lake trout Salvelinus namaycush. The studyˈs baseline was an extensive random survey in 1980 of the areaˈs anglers with respect to Lake Michigan fishery resources. The 1984 lake trout issue was addressed by a restudy involving a small dimensional subsample of 1980 respondents and was cross‐validated with ethnographic interviews. The findings suggest that anglers have responded over time to the stateˈs policy proposals in a manner consistent with a stable value system that is not seriously masked by changes in short‐term attitudes about the fishery. The results further indicate that, once a good cultural data base is established, the sociocultural impacts of proposed fishery policies can be evaluated inexpensively by a restudy approach.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/141485/1/tafs0503.pd

    Reefs from space : satellite imagery, marine ecology, and ethnography in the Dominican Republic

    Coral reef bleaching is an obvious indication that coastal marine ecosystems are being stressed. However, bleached reefs alone are poor indicators because they reflect the final stages of stress. This research project used multidate satellite imagery to look for coral reef changes as indicators of stress. Findings suggest that (1) satellite imagery can be used to identify small-scale changes in coastal marine ecosystems, including coral reefs; (2) remote sensing, marine ecology, and ethnographic data can be integrated to suggest potential causes of coral reef stress; and (3) changes in reef, seagrass, and mangrove ecozones are more closely tied to fishing, tourism, and land use practices than to global warming

    Native knowledge of great lakes ecology: Climate changes to Odawa lands

    Climate change has been observed for hundreds of years by the plant specialists of three Odawa Tribes in the Upper Great Lakes along Lake Michigan. Sleeping Bear Dunes National Lakeshore (SLBE) is the focus of two National Park Service (NPS) studies of Odawa Traditional Ecological Knowledge (TEK) of plants, ecosystems, and climate change. Data collected during these studies contributed to developing Plant Gathering Agreements between tribes and parks. This analysis derived from 95 ethnographic interviews conducted by University of Arizona (UofA) anthropologists in partnership with expert elders appointed by tribes. Odawa elders recognized in the park 288 plants and five habitats of traditional and contemporary concern. Tribal elders explained that 115 of these traditional plants and all five habitats are known from multigenerational eyewitness accounts to have been impacted by climate change. The TEK study thus represents what Odawa people know about the traditional environment and thus provides a foundation for more complex government-to government relationships between Odawa tribes and the NPS. These research findings are neither intended to test Native TEK nor the climate findings of Western science. It should however be pointed out that both are in general agreement about what has happened due to climate change and thus there is now a TEK data base for co-stewardship
