| Six novel polymorphic microsatellite markers were isolated from enriched libraries in Myrica faya Ait., recently renamed Morella faya , (fayatree, firetree, or firebush) in order to examine the genetic diversity in natural populations. Also, test cross-specific amplification and genetic diversity in Myrica rivas-martinezii, which is endemic on the Canary islands. Microsatellite loci were screened in 225 individuals of both species from different islands of the Canarian archipelago. All markers were successfully amplified from both Myrica species, with an average number of 6.5 and 9.3 alleles per locus in M. rivas-martinezii and M. faya , respectively. There was no evidence for linkage disequilibrium between loci, and the probability of null... |

| Analysis of water level and current meter series from different locations on the island shelf of Gran Canaria reveals strong variations in tidal properties. Semidiurnal sea level amplitudes agree with the results obtained from global tidal models for this region only on the northern coast of the island, while they decrease towards the southwest (10 cm difference for the M-2 constituent). Semidiurnal currents present maxima at the southeastern and northwestern extremities of the island (30-40 cm s(-1) for M-2) and minima in the north-northeast and southwest (3-6 cm s(-1) for M-2), showing simultaneous strong changes in the phase. Diurnal levels and currents display smaller variations than the semidiurnal band. The behaviour of semidiurnal constituents is... |

| The catch from bottom longline stations sampled from a series of research cruises around Lanzarote and Fuerteventura (Canary Islands, NE Atlantic) was analysed in terms of fish distribution, density and diversity. The distribution of the number of species and individuals caught per station appeared to fit well the Poisson and Exponential distribution function, respectively. In particular, the parameter of the Poisson's distribution appeared to provide an index of the point (at station scale) diversity, and its confidence interval, allowing for statistical comparisons. The relationships between point diversity, the alpha diversity (in the depth strata) and the beta diversity (along the depth gradient) were investigated. Around the islands, the density and... |

| The West Palaearctic species of the genera Gildoria Hedqvist, 1974, and Platyspathius Viereck, 1911 (Braconidae: Doryctinae) are revised. Five new species are described and illustrated: Gildoria elongata spec. nov. from Canary Islands, G. gijswijti spec. nov. from France, G. iberica spec. nov. from Spain, G. striata spec. nov. from Morocco and Platyspathius europaeus spec. nov. from France and Italy. The genus Gildoria is re-instated, Gildoria anthaxiae (Belokobylskij, 1983), G. grandis (Fahringer, 1930), G. planus (Ratzeburg, 1848), G. similis ( Bouc˘ek, 1955) and G. titubata (Papp, 1985) are new combinations, and Dendrosotinus ilanotensisC ˘ apek, 1992, is synonymized with Gildoria titubata (Papp, 1985). Doryctes lenticularis Granger, 1949, is designated... |

| Seven species of Tubificidae are recorded from the Canary Islands, viz. Heterodrilus amplus n. sp., Coralliodrilus leviatriatus Erséus, 1979, Limnodriloides agnes Hrabĕ, 1967, L. janstocki n. sp., Aktedrilus cuneus Erséus, 1984, A. parvithecatus (Erséus, 1978), and Tubifex tubifex (Müller, 1774); the two latter taxa are reported also from the Cabo Verde Islands. All taxa except T. tubifex are marine and there is no evidence of endemism in the freshwater oligochaete fauna of these islands. Heterodritus amplus has short, spindle-shaped, heavily muscular atria; they are morphologically unique within the genus. Limnodriloides janstocki has modified spermathecal setae; it is distinguished from similar species by its long atrial ducts and deep, elaborate... |

| Lovenula (Neolovenula) alluaudi is widespread on Lanzarote, where it occurred at 22 of the 105 stations. On Fuerteventura it was found at only 2 of the 53 stations, both in the extreme northwest part of the island. It was also found in a reservoir on the south side of the small island of Alegranza. Samples collected at several hundred stations in the other Canary Islands failed to yield a single calanoid, supporting the belief that the eastern islands are fragments of the African continent that drifted to deeper waters. Males outnumbered females in about 2/3 of the samples, often heavily. |
