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; ...
Movement of fishes (Grunts: Haemulidae) across the coral reef seascape: A review of scales, patterns and processes
(Caribbean Journal of Science, Vol. 45, No. 2-3, 304-316, 2009, 2009)
Reef fish movements over short and long time frames have important consequences for identifying essential fish habitat, quantifying ecological flows across the seascape and designing marine reserves.
We use grunts (Haemulidae) ...
Coral Reef Ecosystem Studies: Integrating Science and Management in the Caribbean
(Caribbean Journal of Science, Vol. 45, No. 2-3, 134-137, 2009, 2009)
Sediment transport and the distribution of shallow-water gorgonians
(Caribbean Journal of Science, Vol. 45, No. 2-3, 254-259, 2009, 2009)
The objective of this study was to provide evidence supporting the contention that sediment transport (bedload) is a major environmental factor controlling the distribution of shallow-water gorgonian
species. Gorgonians ...
Coupling of humans, habitats and other species: a study of the fishers’ traditional ecological knowledge (TEK) in La Parguera
(Caribbean Journal of Science, Vol. 45, No. 2-3, 363-371, 2009, 2009)
For generations, fishermen have constructed, shared, and refined knowledge (Traditional
Ecological Knowledge) from their perceptions of habitats and species. Following our earlier work in La Parguera, Southwest Puerto Rico, ...
Nutrient distribution across the insular shelf of La Parguera, Puerto Rico: assessment by algal tissue nitrogen
(Caribbean Journal of Science, Vol. 45, No. 2-3, 181-190, 2009, 2009)
A survey was conducted to investigate possible presence of an inshore to shelf edge gradient in % nitrogen (%N) and stable nitrogen isotope ratio (δ 15 N; ‰ vs. air) in tissues of the rhodophyte Acanthophora
spicifera and ...
Nocturnal fish movement and trophic flow across habitat boundaries in a coral reef ecosystem (SW Puerto Rico)
(Caribbean Journal of Science, Vol. 45, No. 2-3, 282-303, 2009, 2009)
Few studies have quantified the extent of nocturnal cross-habitat movements for fish, or the influence of habitat adjacencies on nutrient flows and trophodynamics. To investigate the patterns of nocturnal
cross-boundary ...
Dynamics of shelf edge coral reef-associated macroalgae at La Parguera, Puerto Rico
(2009)
Percentage cover of coral reef associated algae increased significantly from 2003 to 2007 at two shelf edge sites in southwest Puerto Rico (42.8 % to 75.3% at Weinberg Reef and 67.4% to 81.8% at El Hoyo).
While the increase ...
Spatial and temporal patterns of water quality indicators in reef systems of southwestern Puerto Rico
(Caribbean Journal of Science, Vol. 45, No. 2-3, 168-180, 2009, 2009)
Baseline information on the water quality status of coral reefs and associated habitats of La Parguera, southwestern PR, is presented. Measurements of temperature, salinity, chlorophyll a , turbidity, fluorescence of ...
Spatial and temporal variability in juvenile coral densities, survivorship and recruitment in La Parguera, southwestern Puerto Rico
(Caribbean Journal of Science, Vol. 45, No. 2-3, 269-281, 2009, 2009)
Juvenile coral survivorship (the proportion of juvenile colonies surviving from t 1 to t 2 ) was assessed by counting, photographing and mapping all juveniles found in 2003 within random permanent 0.25m 2 quadrats at four ...
