Resumen:
Fragments of dead coral belonging to Pocillopora Lamarck, 1816 were used during a 1-year period as artificial micro-habitats and positioned at a coral reef community at Islas Marietas, Bahía Banderas, on the west coast of Mexico, to attract and capture isopods. Three species of isopods, totaling 961 specimens were collected. The dominant species was Joeropsis dubia (Menzies, 1951) (Joeropsididae) (83.03% of the total number of specimens), followed by Califanthura squamosissima (Menzies, 1951) (Paranthuridae) (9.78%), and Paracerceis sculpta (Holmes, 1904) (Sphaeromatidae) (7.18%). The average density of isopods was of 12.0 × 10-2 ind. • cm-2. A positive relationship between water temperature and total density of individuals during the sampling period was found. Annual water temperature changes influenced the abundance of each species in a similar way, with the higher abundances associated to the lower temperatures, which is also related to an increase in primary productivity and the presence of upwellings in the area. © 2013 Koninklijke Brill NV, Leiden.
