The Tropics

Picking up in the early 1920s, this chapter tracks the shift of radio technology from military to commercial uses. It follows linkages among the changing material conditions for Caribbean workers, the radio industry’s search for materials like mica and bakelite, and the generation of new markets. Having placed broadcasting in its ecological and political contexts, the chapter uses the trajectories of two amateur radio operators, John Grinan, a New Yorker/Jamaican son of a plantation owner and a member of the team which produced the first transatlantic wireless signals, and Frank Jones, an American plantation manager in Cuba, famous for his self-promoting shortwave transmissions to recover the world of the tinkerers’ romance with an ether jammed with distant sounds. It traces the creation of audiences and publics for the emerging technology, arguing that radio appealed to listeners not because it shrank distances, but because it underscored them, demarcating the Caribbean as exotic and remote. Ironically, it was the deeper technological connections that would propel the mapping of these imagined boundaries between the “tropics” and “the world.”

Sclerosponges secrete a basal crystalline and aspicular skeleton of calcium carbonate, either aragonite or calcite, above which lies a thin layer of living tissue which also secretes siliceous spicules and collagenous fibers. The tripartite skeleton of sclerosponges distinguishes them from all other sponges and also from all other multicellular animals, no one of which has an abundant quantity of two disparate minerals helping to make up its skeleton. The cell types and their organization as well as what little is known about their development indicate that the sclerosponges are related to the demosponges. Sclerosponges are inhabitants of shaded crevices, caves and tunnels on coral reefs in both the Caribbean and Indo-Pacific regions. The range of only one species, Merlia normani Kirkpatrick, extends from the tropics into the warm temperate waters of the Mediterranean Sea.

Abstract Pteris tripartita is a terrestrial fern native to the tropics of the Old Word, introduced to the New World as an ornamental, with records of its being sold in nurseries in Florida (USA) in the 19th century. It is naturalized at scattered localities from Florida to northern South America, including the Caribbean. It is reported as invasive in Cuba and the south of Florida, USA. Its invasiveness in Cuba is due to its high reproductive capacity and its spread into secondary vegetation and cultivated lands in the eastern part of the country. In southern Florida, it is considered as a moderately invasive species, recorded as escaping cultivation in 1928. It is invasive in floodplain wetlands, basin wetlands and mesic uplands, displacing native species. It is not reported as invasive in its native range. It is regarded as a critically endangered species in India.

PRECODEPA was formed with the purpose of coordinating research and extension to improve small-farm potato production. The program involves 9 countries in North, Central America and the Caribbean with the cooperation of the International Potato Center (CIP). Research and extension work was planed based on identified bottlenecks. Work was coordinated when similar bottlenecks were identified in different regions and/or countries. The project strategies emphasized the following: training of personnel to coordinate the work between extension and research; development of integrated pest management (IPM) practices; technology generation and validation trials on farmers' fields, and market development for commercialization purposes. The success of this unique program should serve as a model for similar agricultural projects in the future.

The effect of harvest interval (HI), six-, nine-, and 12-wk, and season of growth (winter, spring, summer, and fall) on crude protein (CP) and neutral detergent fiber (NDF) was studied with rhizoma perennial peanut (RPP) TARS line nos. 17033, 17050, 17052, and 17097 (PI nos. 276233, 262826, 262833, and 262839, respectively) and cv Florigraze and Arbrook at the Lajas Agricultural Experiment Substation. The same parameters were evaluated with PI nos. 276233, 262839, and cv Florigraze at the Juana Díaz Substation. The overall mean CP concentration for RPP, across HI and season of growth was 16.3 and 15.5% in the Lajas and Juana Díaz studies, respectively. In both trials, accession 17033 had the lowest (14.2%) and accession 17097 the highest (16.7%) CP values (P < 0.05). Harvest interval negatively influenced CP concentration (P < 0.01). An increase in HI from six to 12 weeks resulted in a reduction of CP from 17.3 to 15.5%, and from 16.5 to 13.7% in the Lajas and Juana Díaz studies, respectively. In the latter study the CP concentrations of forage harvested at six and nine weeks were similar. Differences in NDF among RPPs were significant (P < 0.05) in both trials. In both, accession 17033 had the highest (49.9%) and accession 17097 the lowest (48.1%) concentration. Increasing HI resulted in quadratic increases (P < 0.01) in NDF concentration. Results for the six-, nine- and 12-wk intervals were 47.8, 50.9, and 51.8% at Lajas and 45.8, 44.5, 52.0% at Juana Díaz, respectively. Season of growth did influence chemical composition of RPP; however, unlike the pattern observed in tropical grasses, the chemical composition of RPP was better in the seasons of greater forage yield (spring and summer). These results show the excellent potential for high nutritive value of RPP when grown in the Caribbean tropics.

The Gothic is undergoing a pronounced resurgence in academic and popular cultures. Propelled by fears associated with massive social transformations produced by globalisation, the neoliberal order and environmental uncertainty – tropes of the Gothic resonate. The gothic allows us to delve into the unknown, the liminal, the unseen; into hidden histories and feelings. It calls up unspoken truths and secret desires.In the tropics, the gothic manifests in specific ways according to spaces, places, cultures and their encounters. Within the fraught geographies and histories of colonisation and aggression that have been especially acute across the tropical regions of the world, the tropical gothic engages with orientalism and postcolonialism. The tropics, as the region of the greatest biodiversity in the world, is under enormous stress, hence tropical gothic also engages with gothic ecocriticism, senses of space, landscape and place. Globalisation and neoliberalism likewise impact the tropics, and the gothic imagery of these ‘vampiric’ capitalist forces – which impinge upon the livelihoods, traditions and the very survival of peoples of the tropics – is explored through urban gothic, popular culture, posthumanism and queer theory.As the papers in this special issue demonstrate, a gothic sensibility enables humans to respond to the seemingly dark, nebulous forces that threaten existence. These papers engage with specific instances of Tropical Gothic in West Africa, the Caribbean, Latin America, Southeast Asia, northern Australia, and the American Deep South.

Shallow-water (0–100 m depth) hydroid faunas reported from 26 locations along the western North Atlantic coast between the high Canadian Arctic archipelago and the Caribbean Sea were compared. Species numbers varied widely between locations, but were highest in the tropics and subtropics, lowest in arctic and subarctic waters, and intermediate in mid-latitudes. Percentages of species producing free medusae were lowest in high latitudes, intermediate in low latitudes, and highest in mid-latitudes (especially in estuaries). In a numerical analysis, similar hydroid faunas were identified at locations (i) between the high Canadian Arctic islands and the Strait of Belle Isle off western Newfoundland; (ii) between the Gulf of St. Lawrence and Chesapeake Bay; (iii) between North Carolina and southeastern Florida (south as far as St. Lucie Inlet), and including the northern Gulf of Mexico; (iv) in the Caribbean Sea, together with Dry Tortugas and the oceanic island of Bermuda. The greatest change in hydroid species composition along the coast appeared to occur around Cape Hatteras. An assemblage on the continental shelf off the middle Atlantic states of the United States appeared to be distinct because of its low hydroid diversity. Faunistically, however, its affinities were decidedly with assemblages at locations between the Gulf of St. Lawrence and Chesapeake Bay. In addition to latitudinal changes in faunal composition, dissimilarities in hydroid species assemblages were noted between certain inshore and offshore locations at comparable latitudes. Numerical classification of locations provides additional evidence for delineation of biogeographic regions along the western North Atlantic coast.

Black Nightshades

The Morelloid Clade, also known as the black nightshades or “Maurella” (Morella), is one of the 10 major clades within the mega-diverse genusSolanumL. The clade is most species rich in the central to southern Andes, but species occur around the tropics and subtropics, some extending well into the temperate zone. Plants of the group are herbaceous or short-lived perennials, with small white or purplish white flowers, and small juicy berries. Due to the complex morphological variation and weedy nature of these plants, coupled with the large number of published synonyms (especially for European taxa), our understanding of species limits and diversity in the Morelloid Clade has lagged behind that of other major groups inSolanum. Here we provide the second in a three-part series of revisions of the morelloid solanums treating the species occurring in North and Central America and the Caribbean (for the Old World see “PhytoKeys 106”, the third part will treat species of South America). Synonymy, morphological descriptions, distribution maps, and common names and uses are provided for all 18 species occurring in this region. We treat 10 of these species as native, and eight as putatively naturalised, introduced and/or invasive in the region. We provide complete descriptions with nomenclatural details, including lecto- and neotypifications, for all species. Keys to all species occurring in the whole region and for each area within it (i.e., North America, Central America and Mexico, and the islands of the Caribbean), illustrations to aid identification both in herbaria and in the field, and distribution maps are provided. Preliminary conservation assessments are provided for all species. Details of all specimens examined are provided in three Supplementary materials sections.

Calabaza is a pumpkin-like fruit that is grown throughout the tropics and subtropics. In the Caribbean “calabaza” is used in soups and other traditional dishes. In Puerto Rico, the 1987-88 calabaza crop was worth $8 million and the value of the crop in Florida is estimated to exceed $5 million. Mainland production of tropical calabaza types of C. moschata is limited largely to Florida where it is used mostly by those of Cuban descent. Despite the popularity and commercial significance of calabaza, little effort has been directed toward the study of cultural practices or varietal improvement. Only two improved varieties, `Borinquen' introduced by the Puerto Rico Agricultural Experiment Station in the 1940s and `La Primera' introduced by the Florida Agricultural Experiment Station in 1979 are available. Approaches to calabaza improvement including development of plants with shorter vines, incorporation of powdery mildew resistance, and production of uniform, symmetrical, hard-shelled, medium-sized fruit with enhanced nutritional quality in relationship to management systems are discussed.
