The genus Diplotaxis Kirby, 1837 is composed of around 200 species reported from Canada to Panama. The species are most abundantly found in Mexico and the United States. This study reports for the first time the presence of Diplotaxis poropyge Bates, 1887 in Colombia. The individuals are from the departments of Atlántico and Bolívar in the Caribbean region of the country. With this discovery, we update the distribution of the genus to include South America.

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.

Abstract The easterly Caribbean low-level jet (CLLJ) is a prominent climate feature over the Intra-America Seas, and it is associated with much of the water vapor transport from the tropical Atlantic into the Caribbean Basin. In this study, the North American Regional Reanalysis (NARR) is analyzed to improve the understanding of the dynamics of the CLLJ and its relationship to regional rainfall variations. Horizontal momentum balances are examined to understand how jet variations on both diurnal and seasonal time scales are controlled. The jet is geostrophic to the first order. Its previously documented semidiurnal cycle (with minima at about 0400 and 1600 LT) is caused by semidiurnal cycling of the meridional geopotential height gradient in association with changes in the westward extension of the North Atlantic subtropical high (NASH). A diurnal cycle is superimposed, associated with a meridional land–sea breeze (solenoidal circulation) onto the north coast of South America, so that the weakest jet velocities occur at 1600 LT. The CLLJ is present throughout the year, and it is known to vary in strength semiannually. Peak magnitudes in July are related to the seasonal cycle of the NASH, and a second maximum in February is caused by heating over northern South America. From May through September, zonal geopotential gradients associated with summer heating over Central America and Mexico induce meridional flow. The CLLJ splits into two branches, including a southerly branch that connects with the Great Plains low-level jet (GPLLJ) bringing moisture into the central United States. During the rest of the year, the flow remains essentially zonal across the Caribbean Basin and into the Pacific. A strong (weak) CLLJ is associated with reduced (enhanced) rainfall over the Caribbean Sea throughout the year in the NARR. The relationship with precipitation over land depends on the season. Despite the fact that the southerly branch of the CLLJ feeds into the meridional GPLLJ in May through September, variations in the CLLJ strength during these months do not impact U.S. precipitation, because the CLLJ strength is varying in response to regional-scale forcing and not to changes in the large-scale circulation. During the cool season, there are statistically significant correlations between the CLLJ index and rainfall over the United States. When the CLLJ is strong, there is anomalous northward moisture transport across the Gulf of Mexico into the central United States and pronounced rainfall increases over Louisiana and Texas. A weak jet is associated with anomalous westerly flow across the southern Caribbean region and significantly reduced rainfall over the south-central United States. No connection between the intensity of the CLLJ and drought over the central United States is found. There are only three drought summers in the NARR period (1980, 1988, and 2006), and the CLLJ was extremely weak in 1988 but not in 1980 or 2006.

Political violence and human rights abuses are escalating in Haiti, as the country’s nascent democracy deteriorates. Already, the United States and countries in the Caribbean region are developing and implementing policies designed to deter and prevent the arrival of Haitian asylum seekers, despite the fact that the flow of asylum seekers has not yet significantly increased from past years. This paper raises concerns about the failure of the United States to offer protection to Haitian refugees and proposes the implementation of a resettlement program as a partial solution to this systemic failure. The paper endorses the concept of in-country processing of Haitian refugees if done with significant safeguards to prevent further abuses against such applicants.

The larval stages of Tricorythodes fictus Traver, T. cobbi Alba-Tercedor and Flannagan, and T. mosegus Alba-Tercedor and Flannagan are described for the first time based upon reared specimens. The rarely reported Asioplax dolani (Allen) is newly documented from the Austroriparian ecological region of Texas. Leptohyphes zalope Traver, known from the southwestern United States and much of Central America, is newly documented from the Caribbean Islands of Grenada and Tobago. This represents only the second leptohyphid mayfly known from both Continental America and the Caribbean region. Additional Caribbean records of Allenhyphes flinti (Allen) are also given.

The teaching stock within the Caribbean region has been eroded by migration to developed countries. Higher potential earnings are one of the motivating factors to move abroad, but little is known about the extent of the income disparity between countries in the Caribbean and popular destination countries. Teacher salary comparisons are undertaken between selected countries in the Caribbean; Suriname, Trinidad and Tobago, St. Lucia, and Jamaica and popular destination countries, namely; United Kingdom, United States, and Canada using a purchasing power parity (PPP) exchange rate. Results show that newly qualified teachers can earn substantially more abroad, with Canada paying over twice the PPP adjusted salary compared to that offered in Jamaica (133.1%) and Suriname (110.6%). The United States offers the highest earning increases for mid- and late career teachers at over three times that offered in Jamaica (214.5%) and Suriname (223.4%). Canada is a close second across all Caribbean countries, whilst the United Kingdom offers the smallest salary differentials at 153.6% for Jamaica and 64.8% for St. Lucia. The study further reveals that there are salary disparities within the Caribbean, which may be a motivating factor for intra-regional migration.

Jujuyaspis borealis is reported from earliest Ordovician (North American usage) limestones in central Texas and western Utah, the first time this species has been recognized in the United States. Jujuyaspis is a widespread olenid trilobite that occurs near the base of the Tremadoc Series in a variety of lithologies in North and South America, Europe, and Asia. When international agreement is reached on the exact horizon at or near the base of the Tremadoc Series that is to be used as the Cambrian–Ordovician boundary, Jujuyaspis will likely prove to be a very useful taxon for recognition of the boundary interval.

Abstract Albinism has been sporadically recorded in Virginia opossums (Didelphis virginiana) in the United States and Mexico, but records of pigmentation disorders in other Didelphis spp. are rare. The Brazilian common opossum (Didelphis aurita) is a cat-sized nocturnal omnivorous marsupial that inhabits Atlantic and Araucaria forests in South America. A litter of five young Brazilian common opossums was rescued at Espírito Santo state, southeast Brazil, of which two were albinos (one male, one female) and the remaining had normal pigmentation (three males). The two albinos had a complete lack of integumentary and retinal pigmentation, representing the first recorded cases of albinism in this species (and the first record in a Didelphis sp. other than the Virginia opossum).

ResumenEl artículo examina las consecuencias que para los países del Caribe, en especial para los Estados Miembros de la Comunidad del Caribe (CARICOM), tendría el proceso de normalización de relaciones entre Cuba y los Estados Unidos iniciado el 17 de diciembre de 2014 (17D). Sin agotar todos los posibles argumentos y posibilidades, el artículo analiza algunas de las transformaciones ya producidas y sus efectos, así como también se aventura en los impactos que pueden esperarse de este proceso –aún muy reciente y de avance mesurado– para las economías del resto de la región Caribe, en especial del Caribe de la CARICOM.La investigación se basó esencialmente en la revisión bibliográfica –en su mayoría de prensa cubana, estadounidense y caribeña– para la consulta de reportes noticiosos y artículos de opinión. Se consideraron ponencias presentadas por estudiosos del tema en eventos científicos así como las discusiones producidas en estos espacios y, en menor medida, se acudió a la consulta de material académico publicado pues, dada la naturaleza del fenómeno que se analiza –aún en pleno desarrollo- los libros y artículos que evalúan los impactos del 17D más allá de lo que sucede en Cuba y los Estados Unidos son relativamente escasos. Nuestro estudio se benefició además de datos estadísticos publicados en medios cubanos y estadounidenses y en información facilitada por las Embajadas de Cuba radicadas en las dos economías líderes de la CARICOM: Jamaica y Trinidad y Tobago, principales socios comerciales de Cuba dentro del espacio CARICOM.Palabras clave: Cuba, Estados Unidos, Caribe, CARICOMO Restabelecimento das Relações Diplomáticas entre Cuba e Estados Unidos: possibilidades para o Caribe da CARICOMResumoO artigo examina as consequencias para os países do Caribe, em especial para os Estados Membros da Comunidade do Caribe (CARICOM), do processo de normalização das relações entre Cuba e os EUA, iniciado em 17 de dezembro de 2014.

Without exhausting all possible arguments and possibilities, the paper discusses some of the changes and their effects, but also explores the expected impacts of this process on the economies of the rest of the Caribbean region, especially the Caribbean CARICOM.The research was based on literature review, taking into consideration mostly Cuban, American and Caribbean press for the consultation of news reports and articles.  The paper considered papers presented by scholars in scientific events as well as discussions produced in these spaces  and, to a lesser extent, consulted academic publications, because, given the nature of the phenomenon being analysed, books and papers assessing the impacts of 17D beyond what happens in Cuba and the United States are relatively rare. Our study also benefited from statistics published in Cuban and US media and information provided by the embassies of Cuba filed in the two leading economies of CARICOM: Jamaica and Trinidad and Tobago, Cuba's main trading partners within the space of CARICOM.Keywords: Cuba, United States, Caribbean, CARICOM
