Abstract
Introduction: The El Pelado Marine
Reserve is an important protected
area of the Ecuadorian coast due
to the connectivity it has with other
marine protected areas. Objective:
Identify patterns of spatial variation in
the community structure of shallow fund
macrobenthos. Materials and Methods:
Ten sites were sampled in the area near
the coast and the El Pelado Islet. The
abundance of macroinvertebrates and
sessile organisms was estimated visually
by diving along two parallel transects
parallel to the coast. Each transect was
50 m long and 5 m wide, with a total
area of 500 m2 per location. Salinity,
pH, residual chlorine, oxygen, floating
material, fecal coliforms, mercury, oils
and fats were recorded on the sea
surface. Results: 92 species were
identified (86 species of invertebrates
and 6 species of macroalgae); the best
represented group was the cnidarians
with 31 species from 13 families, followed
by the molluscs with 15 species from 11
families. The species with higher average
abundances were of macroinvertebrates
Echinometra vanbrunti (21.54%), sessile
organisms Bugula californica (34.2%).
Conclusions: No significant differences
were found in the diversity, richness and
equity of macrobenthic species between
study areas.
