- Check-list of interstitial polychaetes from intertidal and shallow subtidal soft bottoms of Tenerife, Canary IslandsPublication . Riera, Rodrigo; Núñez, Jorge; Carmen Brito, María delA check-list of polychaete species from two stations on the south coast of Tenerife (Los Abrigos and Los Cristianos) at two different tidal levels, intertidal and shallow subtidal (3 m depth) is presented. A total of 47 species were collected, the hesionid Microphthalmus pseudoaberrans Campoy & Viéitez, 1982 and the spionids Rhynchospio glutaea (Ehlers, 1897) and Spio filicornis (O.F. Müller, 1776) being the most abundant. With 18 species the family Syllidae is the most diverse, followed by the Spionidae and Paraonidae with 6 and 5 species, respectively. The interstitial polychaetes found are represented by both meiofaunalsized and small-sized macrofaunal species.
- Effects of granulometric gradient on macrofaunal assemblages in Los Cristianos harbour (Tenerife, Canary Islands)Publication . Riera, Rodrigo; Monterroso, Óscar; Núñez, JorgeAlong the rapid increase of coastal tourism worldwide, evidence is accumulating on the numerous environmental coastal impacts that it causes on marine environments. One of the most important anthropogenic pressures is the construction of marinas or recreational harbours. Typically, most of the studies provide snapshots of the spatial distribution of macrobenthic communities inside and outside of the marina area. However, there is no much information about sedimentary dynamics inside the harbour and their effect on macroinfaunal In the innermost stations of Los Cristianos harbour a different macrofaunal community was present, dominated by the amphipods Cheirocratus assimilis and Corophium acutum and the polychaete Nainereis laevigata. Changes in macrofaunal assemblages could be used as early warnings in identifying environmental impacts before they cause major shifts in the marine environment.
- First record of Ligia oceanica (Linnaeus, 1767) (Isopoda: Ligiidae) in the Canary IslandsPublication . Ramírez, Rubén; Riera, RodrigoThis study presents the first record of L. oceanica in the Canary Islands. Additionally, body features between L. oceanica and Ligia italica Fabricius, 1798, the other sea-slater inhabiting the Archipelago, were compared.
- Notes on free living marine nematodes from the Canary Islands: the genus DaptonemaPublication . Riera, Rodrigo; Núñez, Jorge; Brito, María del CarmenTwo species of Daptonema, D. fistulatus (Wieser & Hopper, 1967) and D. hirsutum (Vitiello, 1967) from soft substrates in Tenerife are recorded for the first time for the Ca-nary Islands. These species are described and geographical variability is discussed. Fur-thermore, meristic and ecological data are presented.
