Description

Transect surveys enumerating seagrass, algal cover and benthic invertebrates were conducted at multiple sites in The Bahamas and Haiti in June 2014. The experiments utilized artificial reefs that mimic natural patch reef habitats, concentrating fishes at high densities.

Methods & Sampling

Dataset acquisition description

Species of seagrass, algae, other benthic cover (e.g., sponge, coral) or invertebrate species were counted from 1 m^2 quadrats. For seagrasses, the number of seagrass shoots were counted within 10 x 10 cm quadrats placed randomly within the larger 1 m^2 quadrat. Percent coverage was the proportion of 1 m^2 quadrat covered by that species, as measured on the standard Braun-Blanquet scale:
<5% (1 individual) – 0.1
<5% (few individuals) – 0.5
<5% (many individuals) – 1
5-25% - 2
25-50% - 3
50-75% - 4
75-100% - 5
Benthic invertebrates such as sponges, molluscs and starfish were counted from the 1 m^2 quadrats.
