Changes in Ant Species Richness and Composition During Plant Secondary Succession in Puerto Rico
(Caribbean Journal of Science, Vol. 43, No. 2, 244-253, 2007, 2007-12)
In general, faunal diversity increases with forest age; therefore, we predict that ant species richness in secondary forests will increase during succession and species composition will vary among different stages of ...
A First Survey of the Earthworms of Bosque del Pueblo, Puerto Rico
(Caribbean Journal of Science, Vol. 42, No. 3, 366-370, 2006, 2006-12)
The oligochaeto fauna of Bosque del Pueblo, located in the central mountain region of Puerto Rico, was surveyed for the first time. Organisms were hand-sorted from forty two samples from three typical plant associations ...
Impact of a White Plague-II Outbreak on a Coral Reef in the Archipelago Los Roques National Park, Venezuela
(Caribbean Journal of Science, Vol. 41, No. 4, 815-823, 2005, 2005-12)
During the last quarter of 2000, an outbreak of white plague disease (WPD-II) caused significant coral tissue mortality in several reef building species (Montastraea species complex, Colpophyllia natans and Stephanocoenia ...
Sexual dimorphism in the timing of flowering in two dioecious trees in a subtropical wet forest, Puerto Rico
(Caribbean Journal of Science, Vol. 46, No. 1, 88-95, 2010, 2010)
In dioecious plants, sexual selection can promote the evolution of differences in the flowering display of males and females. Theory indicates that male reproductive success is principally limited by the number of mates, ...
Spatial and temporal patterns in reef sediment accumulation and composition, southwestern insular shelf of Puerto Rico
(Caribbean Journal of Science, Vol. 45, No. 2-3, 138-150, 2009, 2009)
Effects of terrigenous sedimentation are considered a serious threat to Puerto Rico’s coral reefs. This study assesses: 1) the composition of sediments accumulating at reef sites on the southwestern shelf of
Puerto Rico; ...
Distribution and Relative Abundance of Humpback Whales off Western Puerto Rico during 1995-1997
(Caribbean Journal of Science, Vol. 41, No. 1, 101-107, 2005, 2005-04)
Observations of humpback whales (position, number and presence of calf) were obtained
from a commercial whale-watching vessel during January to March 1995 to 1997 along the northwestern coast of Puerto Rico. These data ...
Occurrence of Juvenile Nassau Grouper, Epinephelus striatus (Teleostei: Serranidae), off Mona Island, Puerto Rico: Considerations of Recruitment Potential
(Caribbean Journal of Science, Vol. 42, No. 2, 264-267, 2006, 2006-12)
In the wider Caribbean, the Nassau
grouper (Epinephelus striatus) is considered a commercially important fish. However, its former abundance has declined precipitously in many areas due to overfishing. In Mona Island, ...
A Non-toxic Scanning Electron Microscopy Method to Study the Reproductive Structures of Agaricales Using Sample Fixation in the Field
(Caribbean Journal of Science, Vol. 41, No. 4, 857-860, 2005, 2005-12)
We present a rapid and non-toxic
method to prepare lamellae and related structures from Agaricales for Scanning Electron Microscopy(SEM). The morphologies of the basidia and basidiospores of Gymnopus subpruinosus, basidiospores ...
Differences Between Epigeic Earthworm Populations in Tank Bromeliads from Puerto Rico and Dominica
(Caribbean Journal of Science, Vol. 42, No. 3, 380-385, 2006, 2006-12)
Large differences were found between the abundance, biomass and distribution of epigeic earthworms in the bromeliads of montane forests in Puerto Rico and Dominica. In Dominica they occurred in more than 90% of plants and ...
Structural Control on Cave Development in Cretaceous Limestone, Southern Puerto Rico
(Caribbean Journal of Science, Vol. 40, No. 2, 276–280, 2004, 2004-08)
Surveys of Sistema Los Chorros (815m length) and Sistema Vientos (600 m) represent the
first cave maps from southern Puerto Rico published in the last quarter century. These are the largest caves known in that area. They ...
