Cabo de Palos – Islas Hormigas: <strong>ecological</strong> studies<br />

� General<br />

o Fish assemblage<br />

Fish assemblages have been extensively studied in the area since 1990, using<br />

underwater visual census (UVC) as main sampling technique. The principal<br />

objective has been to study the fish-habitat structure relationships at several<br />

spatial scales, from 10s to 1000s metres (García Charton & Pérez Ruzafa<br />

1998, 2001). Special mention has to be done to the regular coming up <strong>of</strong><br />

“thermophilic” warm-Atlantic species (e.g. Serranus atricauda, Pseudocaranx<br />

dentex, Parapristipoma octolineatum, Sparisoma cretense, Scorpaena<br />

maderensis) within the Cabo de Palos – Islas Hormigas Marine Reserve<br />

(hereafter CPIHMR) and neighbouring <strong>areas</strong>, probably due to the gradual<br />

warming <strong>of</strong> seawater in south-western Mediterranean. Genetic studies have<br />

been undertaken in the area, taking the species Diplodus sargus as model<br />

(González Wangüemert et al. 2002, 2004).<br />

o Benthic communities<br />

First works, prior to the start <strong>of</strong> protection measures, were devoted to study<br />

the biology, ecology and distribution <strong>of</strong> some benthic taxa, such as molluscs<br />

(Templado 1961, 1962; Templado 1980, 1982a, 1982b, 1982c; Templado &<br />

Llansó 1981; Templado et al. 1983), and echinoderms (López Ibor & Galán<br />

1982; López Ibor et al. 1982; Pina & Pérez Ruzafa 1984; Pérez Ruzafa &<br />

López Ibor 1987). Later, authors undertook the mapping and semiquantitative<br />

characterization <strong>of</strong> benthic biocœnoses in the area (Ros et al.<br />

1984, 1986; Pérez Ruzafa et al. 1991; Calvín et al. 1999), which is presently<br />

being updated by the Regional Government.<br />

UVC monitoring program show how CPIHMR harbours a very rich and diverse<br />

fish assemblage as compared to un<strong>protected</strong> <strong>areas</strong>, showing evidence that<br />
