| radial variation in sap flow in five laurel forest tree species in tenerife, canary islands. | variations in radial patterns of xylem water content and sap flow rate were measured in five laurel forest tree species (laurus azorica (seub.) franco, persea indica (l.) spreng., myrica faya ait., erica arborea l. and ilex perado ait. ssp. platyphylla (webb & berth.) tutin) growing in an experimental plot at agua garcía, tenerife, canary islands. measurements were performed around midday during warm and sunny days by the heat field deformation method. in all species, water content was almost co ... | 2000 | 12651490 |
| photoperiodic response of the hypothalamo-pituitary-gonad axis in male and female canaries, serinus canaria. | although the gonadal photoperiodic response and its influence upon the song control system in canaries have been extensively studied, photoperiodic regulation of the gnrh system has not been investigated. to examine the relationship between photoperiod and the reproductive neuroendocrine system in male and female canaries, three groups of canaries were exposed to chronic short days (8l:16d; phsens), acute long days (18l:6d; phstim) and chronic long days (also 18l:6d; phrefr) to induce the reprod ... | 2003 | 12658720 |

| a predominant european ancestry of paternal lineages from canary islanders. | we genotyped 24 biallelic sites and 5 microsatellites from the non-recombining portion of the y chromosome in 652 males from the canary islands. the results indicate that, contrary to mtdna data, paternal lineages of the current population are overwhelmingly (>90%) of european origin, arguing for a highly asymmetric pattern of mating after european occupation. however, the presence of lineages of indisputable african assignation demonstrates that an aboriginal background still persists (<10%). o ... | 2003 | 12675689 |
| [utility of congenital hypothyroidism screening in neonates for monitoring iodine deficit disorders in the canary islands (spain)]. | newborns in european cities where iodine intake is low have been demonstrated to present high frequencies of transitory hypothyroidism. because the neonatal period is critical for cerebral development, this is a cause for concern. published studies (who/unicef/iccidd) indicate that neonates with a thyroid-stimulating hormone (tsh) concentration of more than 5 mu/ml revealed by screening for congenital hypothyroidism present mild iodine deficiency. | 2003 | 12681185 |
| intraspecific evolution of canary island plecotine bats, based on mtdna sequences. | island differentiation and relationships with congenerics were investigated in the endemic canary island bat plecotus teneriffae, based on approximately 1 kb of mtdna from the 16s rrna and cytochrome b genes. p. teneriffae had closer affinities with p. austriacus than with p. auritus. levels of differentiation between canary islands were quite high relative to pipistrelle-like bats, consistent with philopatric behaviour in the plecotus genus. cladogenesis within p. teneriffae appears to have occ ... | 2003 | 12692583 |

| finite-frequency tomography reveals a variety of plumes in the mantle. | we present tomographic evidence for the existence of deep-mantle thermal convection plumes. p-wave velocity images show at least six well-resolved plumes that extend into the lowermost mantle: ascension, azores, canary, easter, samoa, and tahiti. other less well-resolved plumes, including hawaii, may also reach the lowermost mantle. we also see several plumes that are mostly confined to the upper mantle, suggesting that convection may be partially separated into two depth regimes. all of the obs ... | 2004 | 14657505 |
| content of aliphatic hydrocarbons in limpets as a new way for classification of species using artificial neural networks. | it is demonstrated that biological species like limpets can be classified according to their level of n-alkanes when artificial neural networks are applied. marine intertidal and subtidal limpets of the canary islands (spain), patella piperata, patella candei crenata and patella ulyssiponensis aspera were selected as bioindicator organisms. samples were collected at four stations on the coasts of fuerteventura. concentration of n-alkanes in the soft tissues of the limpets has been determined by ... | 2004 | 14664834 |
| multiple disturbances accelerate invasion of reed canary grass (phalaris arundinaceal.) in a mesocosm study. | disturbances that intensify with agriculture and/or urban development are thought to promote the spread of invasive plants, such as the clonal perennial reed canary grass (phalaris arundinaceal). to test this relationship and interactions among disturbances, we subjected wet prairie assemblages within 1.1 m(2) mesocosms to invasion by phalaris and addition of nutrients, sediments, and flooding. species richness decreased with the application of sediments and/or flooding of 4 consecutive weeks or ... | 2004 | 14669006 |
| [trends in mortality and years of life lost related to alcohol in the canary islands, spain [1980-1998]]. | the aim of this article was to describe death rates and years of life lost prematurely (yllp) in relation to alcohol consumption in the canary islands. the study covered the period between 1980 and 1998. | 2003 | 14670253 |
| [childhood and adolescent obesity in spain. results of the enkid study (1998-2000)]. | obesity is a chronic disease with a complex multifactorial nature which typically begins during childhood and adolescence. it represents one of today's most critical and escalating public health concerns for this segment of the population. the lack of obesity prevalence data at national level prompted the enkid study (1998-2000), which was designed to evaluate the food habits and nutritional status of spanish children and youth. | 2003 | 14678693 |
| radiation, diversity, and host-plant interactions among island and continental legume-feeding psyllids. | island archipelagos and insect-plant associations have both independently provided many useful systems for evolutionary study. the arytainine psyllid (sternorrhyncha: hemiptera) radiation on broom (fabaceae: genisteae) in the canary island archipelago provides a discrete system for examining the speciation of highly host-specific phytophagous insects in an island context. phylogenetic reconstructions based on three datasets (adult and nymph morphological characters, and two mitochondrial dna reg ... | 2003 | 14686530 |
| female canaries produce eggs with greater amounts of testosterone when exposed to preferred male song. | male birdsong has a great influence in the stimulation of female reproduction. however, female physiological responsiveness to song may depend on the degree of complexity of male song. this is expected because females of iteroparous organisms may increase their fitness by matching their reproductive investment to the predicted value of each reproductive attempt. to the extent that the expression of male ornaments is a signal of male quality, we expect females to increase their investment when pa ... | 2004 | 14733893 |
| phytophotolysis of hexahydro-1,3,5-trinitro-1,3,5-triazine (rdx) in leaves of reed canary grass. | hexahydro-1,3,5-trinitro-1,3,5-triazine (rdx) was degraded in reed canary grass leaves exposed to simulated sunlight to primary products nitrous oxide and 4-nitro-2,4-diazabutanal. this is the first time that 4-nitro-2,4-diazabutanal, a potentially toxic degradate, has been measured in plant tissues following phytotransformation of rdx. these compounds, along with nitrite and formaldehyde, were also detected in aqueous rdx systems exposed to the same simulated sunlight. results showed that the i ... | 2004 | 14740749 |
| raman spectroscopic analysis of dragon's blood resins-basis for distinguishing between dracaena(convallariaceae), daemonorops(palmae) and croton(euphorbiaceae). | "dragon[prime or minute]s blood" is the name applied to the deep-red coloured resin obtained from various plants. the original source in roman times, used by many cultures and esteemed for its depth of colour and mystical association, was the dragon tree dracaena cinnabari(convallariaceae), found only on the indian ocean island of socotra, (yemen). additional sources emerged later, including another species of dracaena, d. draco, from the canary islands and madeira, and species in the genera dae ... | 2004 | 14752556 |
