Characterization of six microsatellite loci in  Myrica faya  (Myricaceae)   and cross amplification in the endangered endemic  M. rivas-martinezii    in Canary Islands, Spain
Provedor de dados: 74
Autores: González-Pérez,Miguel A.; Newton,Craig; Sosa,Pedro A.; Rivero,Elizabeth; González-González,Edna A.
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...

Variation of the tidal properties around Gran Canaria
Provedor de dados: 5
Autores: Martinez, A; Perez, E; Bruno, M.
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...

Point, alpha and beta diversity of carnivorous fish along a depth gradient
Provedor de dados: 5
Autores: Lorance, Pascal; Souissi, Sami; Uiblein, Franz.
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...

Biometric variation in Spadella cephaloptera on the Canary Islands (Chaetognatha)
Provedor de dados: 16
Autores: Broerse, Alexandra T.C.
Specimens of Spadella cephaloptera from Tenerife, Gran Canaria and Gomera (Canary Islands) were compared biometrically in regards to morphometric and meristic characters. Variation exists among the populations on the islands as well as between the islands. The populations on Gomera seem more distinct from the populations on Tenerife and Gran Canaria than the two latter are mutually. An apparent decline in the number of adults occurs in July, which is related to a decrease in the number of eggs. A shortage of food can explain the reduced fecundity of the specimens. S. cephaloptera prefers habitats protected from the influence of waves.

Lovenula (Neolovenula) alluaudi (Guerne and Richard, 1890) in the Canary Islands (Copepoda: Calanoida: Paradiaptominae). Stygofauna of the Canary Islands, 19
Provedor de dados: 16
Autores: Bowman, Thomas E.
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.

Groundwater and marine intertidal Tubificidae (Oligochaeta) from the Canary and Cabo Verde Islands, with descriptions of two new species
Provedor de dados: 16
Autores: Erséus, Christer.
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...
