Resumen:
We tested the mid-domain effect to evaluate the bathymetric patterns of
annelid polychaete species richness from the Southern Gulf of Mexico as
a possible hypothesis to explain the species richness gradient,
exploring the overlapping of species depth ranges towards the middle
continental shelf. The bathymetric gradient of the number of species was
estimated using the depth ranges of 259 polychaete species and the
mid-domain effect was tested using a Monte Carlo simulation program at
bands of 10 m depth. The carbonate (234 species) and the terrigenous
(121 species) Gulf shelves showed clear differences in species richness
which was characterized by a highly significant presence of polychaetes
with short depth ranges (< 10 m). The distribution of richness could be
described as a cubic polynomial curve but the maximum values for all
case studied (200, 181 and 84 species, for the whole study area, and the
carbonate and terrigenous shelves, respectively) are strongly skewed to
shallow waters (40 m). This is not consistent with the peak of diversity
at 60-70 m predicted by the model. Therefore, the observed patterns
cannot be reproduced by the mid-domain effect, suggesting the existence
of non-random factors affecting the species richness gradients in the
Gulf. We also found a gradient from west to east in species richness
with increasing species richness in the carbonate shelf.
