| Se aislaron cepas nativas de Trichoderma spp. y Phytophthora parasitica en suelos cultivados con jamaica y con alta incidencia de la enfermedad “pata prieta de la jamaica”. La toma de muestras de suelo se ubicó en los municipios de Tecoanapa, Ayutla de los Libres, San Marcos y Juan R. Escudero del estado de Guerrero. Las cepas patogénicas se aislaron de tallo y raíz enfermo con síntomas evidentes de “pata prieta”. Trichoderma spp. se aisló directamente de suelo mediante el método de dilución de esporas en cajas Petri con el medio de cultivo Papa dextrosa agar. Se obtuvieron tres cepas de P. parasitica y 15 cepas de Trichoderma, correspondiendo a las siguientes especies, 8 a T. asperellum, 3 a T. harzianum, 1 a T. virens, 1 a T. inhamatum, 1 a... |

| Marine capture fisheries in Jamaica is primarily artisanal in nature ansd is conducted maiinly by fishermen operating from canoes. Approximately 95% of these fishermen operate on the coastal shelf and its associated banks. The commercial species harvested comprise bottom-dwelling, coral reef species and free swimming species of finfish. Other fishery resources of commercial value include marine shrimp, conch and lobsters. Catch statistics are not available for all species, but the Department of Fisheries reports a slight decline in fishery production with production decreasing from 16 milion lbs in 1990, despite the fact that fishing efforts have doubled. Over this period the number of registered fishermen has grown from 12 000 to 16 000, al of whom are... |

| Crustaceans remain poorly known from the Miocene of Jamaica. Herein, we report three species from the upper Miocene August Town Formation of Fowl House Spring, parish of St. Thomas, southeast Jamaica; poorly preserved propodi of a mud shrimp, “Callianassa” sp.; the anterior part of the carapace of Mithraculus sp. aff. Mithraculus coryphe (Herbst); and the cirripede Tetraclita sp. cf. T. stalactifera (Lamarck). Mithraculus sp. aff. M. coryphe at Fowl House Spring considerably extends the stratigraphic occurrence of the genus in the Antillean region down into the Miocene. Hitherto, fossil T. stalactifera in the Caribbean was known from the Plio-Pleistocene of Curaçao and the Pleistocene of Venezuela. |

| This research introduces a Geographical Information Systems (GIS) model that predicts the location and relative susceptibility of humid subtropical hillslopes to sheetwash erosion. The extent of the erosion was based on the conservation potential of the existing vegetation cover. This is an original deductive and deterministic model (Potential Erosion Detection, PED) incorporating regionally applicable physical and land use factors thought to be influential. These were climate (agroclimatic zones), topography (aspect and slope angle), soil (texture, drainage, depth, aggregation), vegetation cover and land use (tillage activity). The study looked at surface erosion as a perceived problem in a post-colonial economy. The processes, cause and effect of... |

| Pleistocene brachiopods are poorly known from the Antillean region, but are locally common in forereef deposits of Jamaica (lower Pleistocene Manchioneal Formation) and Barbados (Coral Rock). Of the four species known, two are new. Lacazella sp. cf. L. caribbeanensis Cooper, an encrusting thecideidean, is known from only three valves. Other species are terebratulides. Tichosina inconstanta sp. nov. is a large, ventribiconvex Tichosina species of elongate oval to tear-drop shaped outline, variably uniplicate with a pedicle foramen of moderate diameter. It differs from the similar Tichosina? bartletti (Dall) in having a larger pedicle foramen and a less-marked plication. Argyrotheca barrettiana (Davidson) is a medium to large, usually transverse Argyrotheca... |

| An annotated comprehensive list is provided of all shallow-water sponges (down to 60 m) recently collected and previously recorded from Jamaica. Five new species are described, Plakina jamaicensis, Melophlus ruber, Agelas repens, Stylissa caribica and Hyrtios tubulatus, two of which belong to genera not recorded before from the Western Atlantic (viz. Melophlus and Stylissa). The number of species recorded from shallow waters (reefs, mangroves and lagoons) now amounts to 157 species, several of which, however, are still of uncertain status. |

| James speculated that Paleogene ‘flysch-wildflysch’ deposits of the Caribbean region may all have a related genesis associated with one or more bolide impacts. The principal arguments used to promote this idea were: (1) that many successions may have been dated incorrectly and are actually related to the end Cretaceous (K/T) event and/or other bolide impacts; and (2) common olistostromes may have been transported by impact-related phenomena. The deposits discussed by James included the Richmond and Font Hill formations of Jamaica. The Richmond Formation of the Wagwater Belt is Paleogene, not Cretaceous, and olistostromic blocks are a common feature of the sedimentary succession of Jamaica. No extraterrestrial event need be invoked to support their... |

| Geology has been taught at the University of the West Indies, Mona, since 1961. The associated Geology Museum (UWIGM) opened to the public in 1969/1970, although the idea for such a museum was over 100 years old at that time. The collections of the UWIGM share many hazards with those in museums in other parts of the world, such as dust, insect pests and indifferent specimen records, and some that are less common, such as earthquakes and hurricanes. The curatorship is not tenured. Since the mid 1980s the UWIGM has become a more dynamic visitor attraction in many ways, shaking off its ‘old-fashioned’ appearance and expanding the displays to include, for example, its first mounted vertebrate skeleton. An aggressive collections policy involves establishing a... |

| Jamaica, the third largest of the Greater Antillean islands, exposes various lithological units that are dominated by Cenozoic carbonate rocks including those of the mid-Cenozoic White Limestone Group. This Group is comprised of six formations, the Troy, Swanswick, Somerset, Moneague, Montpelier and Pelleu Island formations. An uncommon but moderately diverse, poorly to moderately preserved softsediment ichnofauna is described herein from several of these, namely the Moneague, Montpelier and Pelleu Island formations, which have yielded 15 ichnogenera represented by 27 ichnospecies. These are: Bergaueria hemispherica? Crimes, Legg, Marcos & Arboleya; Chondrites furcatus Sternberg; Chondrites isp.; Circulichnus montanus Vialov; Dactyloidites ottoi... |

| Terrestrial arthropods are poorly known from the Cenozoic of Jamaica. A probably Late Pleistocene land crab, Sesarma primigenium sp. nov., is described from the Western Cement Company Cave, parish of St. Elizabeth, southwestern Jamaica. The same species is also tentatively recognised from the Late Pleistocene Red Hills Road Cave, parish of St. Andrew, eastern central Jamaica. The propodi of the new species are moderately globose, with an upper margin that is comparatively short and finely granulate ridged; the fingers are obscurely spooned and gaped; and the in-turned fixed finger is in line with, and a litt le shorter than, the basal margin. Of the nine extant endemic members of this subgenus in Jamaica, S. jarvisi Rathbun and S. verleyi Rathbun have... |
