Mangrove forest structure and sediment characteristics were examined in the extensive mangroves of Bocas del Toro, Republic of Panama. Forest structure was characterized to determine if spatial vegetation patterns were repeated over the Bocas del Toro landscape. Using a series of permanent plots and transects we found that the forests of Bocas del Toro were dominated by Rhizophora maugle with very few individuals of Avicennia germinans and Laguncularia racemosa. Despite this low species diversity, there was large variation in forest structure and in edaphic conditions (salinity, concentration of available phosphorus, Eh and sulphide concentration). Aboveground biomass varied 20-fold, from 6.8 Mg ha(-1) in dwarf forests to 194.3 Mg ha(-1) in the forests fringing the land. But variation in forest structure was predictable across the intertidal zone. There was a strong tree height gradient from seaward fringe (mean tree height 3.9 m), decreasing in stature in the interior dwarf forests (mean tree height 0.7 m), and increasing in stature in forests adjacent to the terrestrial forest (mean tree height 4.1 m). The predictable variation in forest structure emerges due to the complex interactions among edaphic and plant factors. Identifying predictable patterns in forest structure will aid in scaling up the ecosystem services provided by mangrove forests in coastal landscapes.

Bocas del Toro is located in the western region of the Republic of Panama. It is part of a province of approximately 8917 km(2) with an estimated 68% of its area covered by tropical rainforest. The area receives 2870 mm/year of rainfall. The dry and rainy seasons are not clearly defined. There are two periods each of low and high rainfall, March and September-October, and July and December, respectively. Mangrove forests, seagrass meadows and coral reefs are vast, covering large areas in the shallow waters surrounding the islands of the archipelago and along the mainland coast. The CARICOMP sites were established in 1998-99 and are periodically monitored following Level I protocol. Herein we describe the sites in a regional context and present the baseline data for each site. This paper fulfills the requirements of the formal site description for CARICOMP monitoring sites.

Nesta pesquisa se propõe analisar a pastoral evangélica latino-americana elaborada por Orlando Costas. Teólogo pastoralista, missiólogo e de origem porto-riquenha, Costas elaborou método e metodologia de pastoral a partir de sua confissão religiosa evangelical em diálogo ecumênico e em consonância crítica com a situação política, econômica, social e religiosa de Porto Rico e da América Latina. Costas, juntamente com Emilio Castro, foi um dos primeiros a lançar as bases para uma pastoral evangélica visando ao homem latino-americano. Criticou o modelo da teologia pastoral norte-atlântica centrada no pastor com sujeito da ação pastoral da igreja alegando ser; repetitiva, profissional e eclesiocêntrica. A pesquisa foi realizada em três passos, que se realizam nos capítulos um, dois e três, respectivamente, compreender o contexto político, econômico, social e religioso da vida de Orlando Costas a partir de Porto Rico, suas experiências de conversão-ruptura dentro da sua tradição religiosa e a nova percepção pastoral; analisar o desenvolvimento histórico teológico da pastoral evangélica, ou seja, os movimentos, conferências, instituições e teólogos que influenciaram o pensamento de Costas; e, apresentar os fundamentos missiológicos e teológicos da pastoral evangélica, em que se demonstra que a pastoral de Costas é missiológico-pastoral, pois assume a missio Dei como princípio arquitetônico e a pastoral como princípio hermenêutico para a ação missional e pastoral. Conclui-se que a proposta de Costas é de uma pastoral evangélica e ecumênica, contextual e autóctone, dentro e fora da igreja.(AU)

Excerpt from EXECUTIVE SUMMARY This report examines the situation of the Haitians in Miami who were formerly incarcerated during 1981 and 1982 in the Immigration and Naturalization Service's Krome Detention Center or other Federal detention centers in the U.S. and Puerto Rico. For convenience, the report refers to all of them as Krome Haitians. This study is based upon a sociological survey of the Krome Haitians and intensive anthropological fieldwork conducted by Dr. Alex Stepick of the Sociology and Anthropology Department of Florida International University with support from the Catholic Services Bureau of Miami. It is the only scientific study of the Krome Haitians and the scientific procedures of the survey complemented by the anthropological fieldwork combine t o produce highly reliable results . To provide context to the conditions of the Krome Haitians, the report compares the characteristics of this population to that of the Haitian Entrants who arrived in 1980 or earlier and provides an update to earlier studies by this author (Stepick 1982) and another by the Behavioral Science Research Institute (1983). The report describes the conditions of the Krome Haitians, including their background in Haiti, experiences in the U.S., past and present employment status , experience with discrimination and social isolation , and adaptation to American society. The report concludes with some specific policy recommendations to state and local agencies and individuals that will assist the Haitians' integration into American society.

The major topographic features, or provinces, beyond the continental slope off the Atlantic coast of the United States are (1) Sohm Plain, (2) Hatteras Plain, (3) Nares Plain, (4) Blake Basin, (5) Blake Plateau-Bahama Banks, and (6) Bermuda Rise. The whole of the described area is commonly referred to as the North American Basin. This basin is bounded on the north by Newfoundland Ridge and on the south by Puerto Rico Trench. Topographic features of note within the basin are the divide and the area of depressions between Sohm and Hatteras Plains, the sharply crested Blake Ridge, and the Puerto Rico Ridge. Recently accumulated data on deep-sea oores has given good evidence that the silt and sand covering the abyssal plains are displaced continental sediments in a virtually quartz-free oceanic environment. These sediments were deposited on a primary volcanic bottom. The primary or volcanic bottom is characterized by abyssal hills and seamounts, and the sediment bottom is characterized by abyssal plains, which extend seaward from the continental margins. On the Blake Plateau, bottom photographs and dredge hauls in the axis of the stream show that locally sediment has been removed and the bottom is paved with crusts and nodules of manganese. Photographs and dredged samples from the outer part of the New England Seamount, Chain and Caryn Peak also indicate extensive encrustations of manganese oxide which acts as a binding agent in areas of ooze or other organic debris and thus helps to stabilize the bottom.

Available overwash records from coastal barrier systems document significant variability in North Atlantic hurricane activity during the late Holocene. The same climate forcings that may have controlled cyclone activity over this interval (e.g., the West African Monsoon, El Niño-Southern Oscillation (ENSO)) show abrupt changes around 6000 yrs B.P., but most coastal sedimentary records do not span this time period. Establishing longer records is essential for understanding mid-Holocene patterns of storminess and their climatic drivers, which will lead to better forecasting of how climate change over the next century may affect tropical cyclone frequency and intensity. Storms are thought to be an important mechanism for transporting coarse sediment from shallow carbonate platforms to the deep-sea, and bank-edge sediments may offer an unexplored archive of long-term hurricane activity. Here, we develop this new approach, reconstructing more than 7000 years of North Atlantic hurricane variability using coarse-grained deposits in sediment cores from the leeward margin of the Great Bahama Bank. High energy event layers within the resulting archive are (1) broadly correlated throughout an offbank transect of multi-cores, (2) closely matched with historic hurricane events, and (3) synchronous with previous intervals of heightened North Atlantic hurricane activity in overwash reconstructions from Puerto Rico and elsewhere in the Bahamas. Lower storm frequency prior to 4400 yrs B.P. in our records suggests that precession and increased NH summer insolation may have greatly limited hurricane potential intensity, outweighing weakened ENSO and a stronger West African Monsoon-factors thought to be favorable for hurricane development.

Marcos Irizarry (Mayagüez, Puerto Rico 1936-San Juan, Puerto Rico 1995) es uno de los artistas plásticos puertorriqueños más destacados e influyentes que creó una de las obras gráficas y pictóricas abstractas más significativas en Puerto Rico y España. La presente investigación tiene como objetivo el estudio y análisis de la obra de Marcos Irizarry. El estudio de la obra de Marcos Irizarry es importante, ya que los trabajos y escritos realizados tanto en Puerto Rico como en España son limitados, y mayormente se basan en el contexto puertorriqueño. El objetivo de esta investigación es contribuir a la historia del arte de Puerto Rico, de modo que se fomente el estudio, y se logre un mayor entendimiento de la abstracción y de la extensa obra gráfica del artista puertorriqueño Marcos Irizarry, sobre todo el que se dio durante las décadas sugeridas y mostrar su trascendencia, su gran legado, su amplio alcance y reafirmar su carácter universal. La hipótesis fundamental de este trabajo se basa en que la obra del artista puertorriqueño, Marcos Irizarry posee características, estéticas, conceptos y rasgos que pueden responder a las estipuladas tanto por el informalismo europeo-español o por la abstracción americana-puertorriqueña. Se concluyó que la obra gráfica realizada entre finales de los cincuenta hasta finales de los setenta, cobra carácter distinto si se ve como parte del proceso estético español de la posguerra o si se la sitúa en el ámbito del arte puertorriqueño...
