AbstractThe late Cretaceous crinoid Uintacrinus socialis Grinnell, which is a potential marker for the base of the Upper Santonian Substage, is reported from the Inoceramus Shales of St Ann's Great River Inlier on the north coast of Jamaica. This is the first record of this species from the Caribbean region and marks its lowest latitudinal distribution reported to date. The Inoceramus Shales are a deep-water clastic mudstone unit which extends the palaeoecological distribution of this crinoid. Uintacrinus socialis proves that the Inoceramus Shales are of Santonian age and will help constrain correlations between the shallow-water platform carbonate/volcaniclastic facies found in the arc successions of the Caribbean and the international chronostratigraphy.

This is the first record of Eleocharis mutata in Florida, and the second record in the continental USA, suggesting a potential natural range expansion of this species from the Caribbean region. A key to species of Eleocharis subg. Limnochloa in Florida is included, along with a site description of the occurrence, visual aids for identification, and a brief discussion of nativity.

Abstract A comprehensive new compilation of North Atlantic tropical cyclone activity for the years 1851–98 is presented and compared with the second-generation North Atlantic hurricane database (HURDAT2) for the same years. This new analysis is based on the retrieval of 9072 newspaper marine shipping news reports, 1260 original logbook records, 271 Maury abstract logs, 147 U.S. marine meteorological journals, and 34 Met Office (UKMO) logbooks. Records from throughout North America and the Caribbean region were used along with other primary and secondary references holding unique land and marine data. For the first time, North Atlantic daily weather maps for 1864/65, 1873, and 1881–98 were used in historical tropical cyclone research. Results for the years 1851–98 include the omission of 62 of the 361 HURDAT2 storms, and the further reduction resulting from the merging of storms to a total of 288 unique HURDAT2 tropical cyclones. The new compilation gave a total of 497 tropical cyclones in the 48-yr record, or an average of 10.4 storms per year compared to 6.0 per year in HURDAT2 less the author’s omissions. Of this total, 209 storms are completely new. A total of 90 hurricanes made landfall in the United States during this time. Seven new U.S. landfalling hurricanes are present in the new dataset but not in HURDAT2. Eight U.S. landfalling hurricanes in HURDAT2 are now considered to have only tropical storm impact or were actually extratropical at landfall. Across the North Atlantic, the number of category-4 hurricanes based on the Saffir–Simpson hurricane wind scale, compared with HURDAT2, increased from 11 to 25, 6 of which made U.S. landfall at category-4 level.

The pelagic macroalgae finches of the Sargassum genus in the Caribbean Sea currently represent a very natural problem due to their negative impact on the tourism industry, fishing industry, the environment and society in general. This work presents an above report of Sargassum that occurred on the north western coast of the Cuban archipelago in March 2019. The macroalgae species identified in the tidal zone were Sargassum fluitans and S. natans, and the specific geographic area where the impact of the upheaval occurred was from the west of Matan-zas bay to Mariel bay. The finches of these macroalgae were cataloged with a moderate magnitude compared to other reports in the Mexican Caribbean and in the Dominican Republic. This order of magnitude was cataloged based on its covered area of 169.3 km and its distribution along the coast in large patches, but very fragmented, despite the prevailing winds from the first quadrant (from north to east) during this period. Other events of this type reported in Cuba and the Caribbean region are taken up and discussed. Keywords: Caribbean Sea, Sargassum fluitans, Sargassum natans, Cuba.

The species Cithaeron praedonius O. P.-Cambridge is recorded from eastern Cuba. This is the first record of the family Cithaeronidae in the Caribbean Region. The presence in Cuba of this species is an accidental introduction, but its source is unknown.

This is the first record of the subfamily Simognathinae for the Brazilian coast. Two new species are described, Acaromantis vespucioi sp. nov. and Simognathus euphractus sp. nov. The description of Simognathus fuscus Viets, 1936 is extended with the inclusion of juveniles description.

In colonial times, French Guiana, located on the north coast of South America, was part of the circum-Caribbean region and participated in the triangular trade. Beginning with their arrival in 1665, Jesuit missionaries had control over the religious affairs for the colony and gained a very influential position within the colonial population until their expulsion (1763-1768). They also participated in the plantation system, as a way to finance the establishment of their evangelization work among the Native people of South America. With their most iconic plantation, the Habitation Loyola (ca 1720-1768), the Jesuits were the first producers of sugar, coffee, and cocoa; over a century of their exploitation more than a thousand slaves were scattered over all their possessions. In this chapter we seek to explore the social dynamics and cultural interactions between the Jesuits, the enslaved Africans, and the Native populations within the plantation system. We begin with a brief review of the plantation studies in French Guiana and the Caribbean, then we address the questions of cultural interaction studies and the creolization process. Our analysis is based on specific sets of artifacts retrieved mainly from a trash deposit associated with the kitchen and the Great House.

<p>Although the Caribbean region is considered amongst the most vulnerable to the impacts of climate and climate change, there are very few regional studies or studies matching the regions small scale and size that evaluate or quantify the impacts of these future changes.  The absence becomes even more stark when the long-term temperature goals (LTTGs) of 1.5°C, 2.0°C and 2.5°C above pre-industrial warming levels are considered. By selecting, validating and downscaling a subset of the Hadley Centre’s 17-member Perturbed Physics Ensemble for the Quantifying Uncertainty in Model Predictions (QUMP) project, future changes for both the LTTGs as well as mid and end of century are evaluated, for the entire Caribbean and its six (6) sub-regional zones. Showing distinct and significant sub-regional variations, on average the Caribbean was found to be 2.1°C (>4°C) warmer and 40% (70%) drier by mid-century (end of century). Analysis of the LTTGS shows that the region surpasses lowest target, 1.5 °C, before the end of the 2020’s and experiences progressive warming that spread equatorward as successive thresholds are attained 2.0°C (2030’s) and 2.5°C (2050´s). The far western, the southern and the eastern Caribbean are found to be up to 50% drier at 1.5°C, with intensifications noted for changes at 2.0°C with a reversal of a wet tendency in the north and central Caribbean. The sub-regional variations that exist shows that although the Caribbean lags the globe in its attainment of the LTTGs some of its six subregions are more comparable to the global than the Caribbean mean with the transition from 1.5°C to 2.0°C seeming to represent a turning point for the Caribbean.</p>

A new cheilostome bryozoan genus Marcusadorea (type species Marcusadorea jamaicensis n. sp. from the north coast of Jamaica) is described and illustrated along with a second species, Coleopora corderoi Marcus, 1949 from Southeast Brazil. A third species, Holoporella tubulosa Canu & Bassler, 1928, described from the Caribbean, but also present in Brazil, is included in this genus and redescribed. At least one Indo-West-Pacific species, “Cosciniopsis” efatensis Tilbrook, 2006, is a congener.

This report offers a brief overview of recent population figures, types of educational programs, and selected topics of present interest and relevance to educators of blind and visually impaired students in the U.S.A., Canada, and the Caribbean. While not intended to be comprehensive or statistically exacting, it is hoped that this discussion will be useful in informing our colleagues in other areas of the world about some of the current concerns of professionals in the North America-Caribbean region.
