Coexistence of Feral Africanized and European Honey Bees (Hymenoptera: Apoidea: Apidae) on St. Croix Island
(Caribbean Journal of Science, Vol. 44, No. 2, 264-266, 2008, 2008-07)
The first evaluation of the feral population of honey bees on the island of St. Croix, US Virgin Islands is performed. Since Africanized bees had been reported in 1994, we expected that, as in the neighboring island of ...
Pharaxonotha portophylla (Coleoptera: Erotylidae), new species and pollinator of Zamia (Zamiaceae) in Puerto Rico
(Caribbean Journal of Science, Vol. 44, No. 3, 321-333, 2008, 2008-12)
Pharaxonotha portophylla, new species (Insecta: Coleoptera: Erotylidae: Pharaxonothinae), is described based on individuals collected on the cones of native populations of Zamia amblyphyllidia D. W. Stevenson and Z. ...
Self-compatibility of microgametophytes in Heliconia bihai (Heliconiaceae) from St. Lucia
(Caribbean Journal of Science, Vol. 44, No. 2, 145-149, 2008, 2008-07)
Potential for physiological self-incompatibility in Heliconia bihai as a mechanism to promote outcrossing was studied in St. Lucia. Our results do suggest that H. bihai is self-compatible. However, plants vary in their ...
Diet of feral goats in Mona Island Reserve, Puerto Rico
(Caribbean Journal of Science, Vol. 44, No. 2, 199-205, 2008, 2008-07)
The presence of feral goats can have detrimental effects to insular ecosystems where native plants have evolved in the absence of these animals. Goat diet information is valuable in determining which species may be most ...
Variation in Mycorrhizal Infection of the epiphytic orchid Ionopsis utriculariodes (Orchidiaceae) on different substrata
(Caribbean Journal of Science, Vol. 44, No. 1, 130-132, 2008, 2008-03)
Substratum effects on the growth and survivorship of the sponge Desmapsamma anchorata
(Caribbean Journal of Science, Vol. 44, No. 1, 83-89, 2008, 2008-12)
La diversidad de los invertebrados sésiles de los arrecifes coralinos depende enormemente de las asociaciones en el substrato y de las interacciones entre especies. En este trabajo describimos efectos asociados al substrato ...
The life history of Helminthora anomala (Nemaliales, Rhodophyta) in culture
(Caribbean Journal of Science, Vol. 44, No. 3, 355-360, 2008, 2008-12)
The life history of Helmithora anomala Vélez & Vega (Nemaliales, Rhodophyta), collected from Puerto Rico was examined in culture. Carpospores from monoecious plants germinated to form freeliving,uniseriate filamentous micro ...
Anoles of St. Vincent (Squamata: Polychrotidae): Population Densities and Structural Habitat Use
(Caribbean Journal of Science, Vol. 44, No. 1, 102-115, 2008, 2008-03)
We examined population densities and structural microhabitat use by Anolis griseus and A.trinitatis at eight sites on the leeward (western) coast of St. Vincent, West Indies. Estimates of population density based on the ...
Growth of Pinus caribaea hondurensis Relative to Spacing and Trunk Diameter on Two Soils in Puerto Rico
(Caribbean Journal of Science, Vol. 44, No. 2, 236-241, 2008, 2008-07)
Analysis of 19-year-old planted Pinus caribaea var. hondurensis on clay and sandy soils in the mountains of Puerto Rico showed the suitability of both sites for tree growth to commercial size. Growth rates were compared ...
Bird Community Dynamics and Habitat Associations in Karst, Mangrove and Pterocarpus Forest Fragments in an Urban Zone in Puerto Rico
(Caribbean Journal of Science, Vol. 44, No. 3, 402-416, 2008, 2008-12)
Puerto Rico’s forest cover decreased to less than 10% in the early 1900’s leaving few forest patches available for migrant and resident birds. In this process of deforestation karst hills and coastal wetlands have been ...
