accumulating pollutants in conifer needles on an atlantic island - a case study with pinus canariensis on tenerife, canary islands.concentrations of potential pollutant elements na, cl, and s were investigated in needles of pinus canariensis grown at 55 field plots in tenerife. microelement concentrations (including heavy metals) were measured at a subset of 18 plots. na and cl concentrations were high at low elevations (up to 8 mg g(-1) cl and 5.5 mg g(-1) na). na/cl ratio close to standard seawater indicated sea spray influence up to 1200 m a.s.l. only at few plots, sulphur concentrations indicated possible pollutant impa ...200515862394
molecular characterization of a new serovar of salmonella bongori 13,22:z39:- isolated from a lizard.three salmonella strains isolated from a lizard (gallotia simoni) in the "isla del hierro" (canary islands, spain) were serotyped as salmonella bongori serotype 13,22:z39:-, which has not been described in the kauffmann-white scheme of salmonella serovars. in order to shed light on the assignment of those strains to the s. bongori species, several genes were amplified and/or sequenced. the irob gene has been reported to be present only in s. enterica, while the inva gene has been described as be ...200515862460
freedom and rules: the acquisition and reprogramming of a bird's learned song.canary song is hierarchically structured: short stereotyped syllables are repeated to form phrases, which in turn are arranged to form songs. this structure occurs even in the songs of young isolates, which suggests that innate rules govern canary song development. however, juveniles that had never heard normal song imitated abnormal synthetic songs with great accuracy, even when the tutor songs lacked phrasing. as the birds matured, imitated songs were reprogrammed to form typical canary phrasi ...200515890887
bumblebees, humble pollinators or assiduous invaders? a population comparison of foraging performance in bombus terrestris.worldwide trade in non-native bumblebees remains largely unrestricted despite well-documented cases where introductions of non-native bees have gone dramatically wrong. within europe, indiscriminate importation of non-native populations of bumblebees (bombus terrestris) for the pollination of glasshouse crops continues on a massive scale. however, no risk assessment has been conducted for these introductions, perhaps because b. terrestris is considered a native species, so shipping populations f ...200515891827
an outbreak of abortions and high neonatal mortality associated with trypanosoma evansi infection in dromedary camels in the canary islands.trypanosoma evansi was diagnosed for the first time in the canary islands (spain) in 1998 in a dromedary camel. seroprevalences of 4.8% up to 9% have been observed using different diagnostic methods. affected animals have been treated but the dissemination of the disease is unknown. this article presents an outbreak of abortions and high neonatal mortality attributable to t. evansi infection in camels as well as the clinical assessment of the affected animals. the patients were diagnosed by rout ...200515893083
the effect of auditory distractors on song discrimination in male canaries (serinus canaria).male songbirds such as canaries produce complex learned vocalizations that are used in the context of mate attraction and territory defense. successful mate attraction or territorial defense requires that a bird be able to recognize individuals based on their vocal performance and identify these songs in a noisy background. in order to learn more about how birds are able to solve this problem, we investigated, with a two-alternative choice procedure, the ability of adult male canaries to discrim ...200515896531
[routine preoperative screening of asymptomatic patients: beliefs and attitudes of anesthesiologists in the canary islands, spain].to identify factors that explain anesthesiologists' inappropriate use of preoperative tests in asymptomatic patients scheduled for elective surgery.200515901024
selectivity of canary hvc neurons for the bird's own song: modulation by photoperiodic conditions.to what extent seasonal factors modify the neuronal functional properties within the nuclei of the avian song system remains an open question. in adult songbirds, neurons of the song premotor nucleus hvc (used as a proper name) exhibit selective responses for the bird's own song (bos). here we examine whether, outside the breeding season, when songs are less stereotyped, hvc neurons of male canaries still respond selectively to the bos produced during this period. in an initial experiment, singl ...200515901776
nuclear ribosomal dna and karyotypes indicate a nw african origin of south american hypochaeris (asteraceae, cichorieae).hypochaeris has a disjunct distribution, with more than 15 species in the mediterranean region, the canary islands, europe, and asia, and more than 40 species in south america. previous studies have suggested that the new world taxa have evolved from ancestors similar to the central european h. maculata. based on internal transcribed spacer (its) sequences and fluorescence in situ hybridization (fish) with 5s and 18s-25s rdna of the previously overlooked hypochaeris angustifolia from moyen atlas ...200515737585
inadvertent exposure to organochlorine pesticides ddt and derivatives in people from the canary islands (spain).in 1998, one of the largest determinations of organochlorine pesticides in a representative sample of a spanish population (682 serum samples from the canary islands) was made in the context of the "canary islands nutrition survey" (enca). in the canary islands, extensive farming areas have been developed in these last decades, with greenhouses dedicated to intensive cultivation using ddt in huge amounts. in spain, similarly to other european countries, ddt was banned in the late 1970s. the pest ...200515740757
antidepressant properties of some hypericum canariense l. and hypericum glandulosum ait. extracts in the forced swimming test in mice.it has been shown in a previous work that the methanol extract obtained from the aerial part in blossom of hypericum canariense l. and hypericum glandulosum ait. was active in the tetrabenazine and forced swimming test. in the present study, the central nervous effect of the aqueous, butanol and chloroform fractions obtained from the methanol extracts of these hypericum species was investigated in mice, particularly in animal models of depression. it was found that the immobility time in the for ...200515740893

molecular phylogenetics of the macaronesian-endemic genus bystropogon (lamiaceae): palaeo-islands, ecological shifts and interisland colonizations.abstract a molecular phylogenetic study of bystropogon l'her. (lamiaceae) is presented. we performed a cladistic analysis of nucleotide sequences of the internal transcribed spacers (its), of the nuclear ribosomal dna, and of the trnl gene and trnl-trnf intergenic spacer of the chloroplast dna. bystropogon odoratissimus is the only species endemic to the canary islands that occurs in the three palaeo-islands of tenerife. this species is not part of an early diverging lineage of bystropogon and w ...200515773944
bradyrhizobium canariense sp. nov., an acid-tolerant endosymbiont that nodulates endemic genistoid legumes (papilionoideae: genisteae) from the canary islands, along with bradyrhizobium japonicum bv. genistearum, bradyrhizobium genospecies alpha and bradyrhizobium genospecies beta.highly diverse bradyrhizobium strains nodulate genistoid legumes (brooms) in the canary islands, morocco, spain and the americas. phylogenetic analyses of its, atpd, glnii and reca sequences revealed that these isolates represent at least four distinct evolutionary lineages within the genus, namely bradyrhizobium japonicum and three unnamed genospecies. dna-dna hybridization experiments confirmed that one of the latter represents a new taxonomic species for which the name bradyrhizobium canarien ...200515774626
coordinated and dissociated effects of testosterone on singing behavior and song control nuclei in canaries (serinus canaria).temperate zone songbirds that breed seasonally exhibit pronounced differences in reproductive behaviors including song inside and outside the breeding season. springlike long daylengths are associated with increases in plasma testosterone (t) concentrations, as well as with increases in singing and in the volume of several brain nuclei known to control this behavior. the mechanisms whereby t can induce changes in behavior and brain, and whether or not these effects are differentially regulated, ...200515777813
polycyclic aromatic hydrocarbons in smoke used to smoke cheese produced by the combustion of rock rose (cistus monspeliensis) and tree heather (erica arborea) wood.in this work, the polycyclic aromatic hydrocarbons (pahs) and their methyl derivatives concentrations have been determined in smoke from the rock rose and tree heather wood combustion. the combustion is done in two types of smokers, kiln and drum, commonly used in the canary islands (spain) to smoke cheese. the low control of the operational conditions justify the great variability of the pahs concentration in the emissions, with values between 251.8 and 2547 microg/m3n. in general, the lowest c ...200515631526
linguistic perception: neural processing of a whistled language.silbo gomero is a whistled language that is a rare and endangered surrogate of spanish, used by shepherds on the island of la gomera in the canary islands for communication over long distances on difficult terrain. here we show that areas of the brain normally associated with spoken-language function are also activated in proficient whistlers, but not in controls, when they are listening to silbo gomero. our findings demonstrate that the language-processing regions of the human brain can adapt t ...200515635400
y-chromosome str haplotypes in the canary islands population (spain).haplotype frequencies of eight y-chromosome str loci (dys19, dys389i, dys389ii, dys390, dys391, dys392, dys393 and dys385) were determined from a sample of 285 unrelated males from canary islands.200515639620
bahia grass pollen specific ige is common in seasonal rhinitis patients but has limited cross-reactivity with ryegrass.perennial ryegrass is a major cause of rhinitis in spring and early summer. bahia grass, paspalum notatum, flowers late into summer and could account for allergic rhinitis at this time. we determined the frequency of serum immunoglobulin (ig)e reactivity with bahia grass in ryegrass pollen allergic patients and investigated ige cross-reactivity between bahia and ryegrass.200515647049

molecular phylogenetics of limonium and related genera (plumbaginaceae): biogeographical and systematic implications.phylogenetic relationships within limonium (plumbaginaceae) are evaluated using sequence data from three plastid regions (rbcl, the trnl intron, and the trnl-trnf intergenic spacer). sixty-six species representing the major genera of staticoideae, including representatives of all sections and genera formerly included in limonium, have been analyzed using four species of plumbaginoideae as an outgroup. analyses of each separate and combined data set yield similar results. afrolimon is embedded in ...200521646141
patterns of genetic divergence of three canarian endemic lotus (fabaceae): implications for the conservation of the endangered l. kunkelii.we examined data for 11 allozyme loci in 14 populations that represent the distribution of the endangered lotus kunkelii, the narrowly distributed l. arinagensis (both endemic to gran canaria), and the broad-ranging l. lancerottensis (endemic to the easternmost canary islands, fuerteventura and lanzarote) to explore and construe patterns of genetic variation and use this data to assess the controversial taxonomic status of l. kunkelii relative to l. lancerottensis. while l. kunkelii maintains lo ...200621642177
reproductive biology of the dioecious canary islands endemic withania aristata (solanaceae).we confirmed functional dioecy of withania aristata via field and greenhouse studies. male flowers are significantly larger. female flowers bear stamens with no pollen; males bear 220?000 grains. stigmata of male flowers senesce in buds. anatomical observations confirm more ovules in females and an ovarian nectary in both sexes. we detected nectar in female flowers in the greenhouse but found no nectar in males. thus, males offer pollen and females nectar. females bear large numbers of fruits an ...200621642194
allozyme diversity within and divergence among species oftolpis(asteraceae-lactuceae) in the canary islands: systematic, evolutionary, and biogeographical implications.plants endemic to oceanic islands represent some of the most unusual and rare taxa in the world. enzyme electrophoresis was used to assess genetic diversity within and divergence among all endemic species of a small genus of plants on the canary islands. our results show that the genus tolpis is similar to many other island groups in having generally low allozyme divergence among species, with the highest divergence found among four groups of endemics. the two rare and highly localized species t ...200621646225
population divergence for heteroblasty in the canary island pine (pinus canariensis, pinaceae).a heteroblastic (or vegetative phase) change is an abrupt manifestation in the general heteroblastic development during the ontogeny of plants. the canary island pine undergoes an especially marked and delayed heteroblastic change, including both the formation of secondary needles on dwarf shoots and the onset of preformed growth. to assess genetic and environmental effects on the heteroblastic change in this species, we followed plants from 19 populations at a dry site and a wetter site. compar ...200621642146
the utility of automated analysis of inter-simple sequence repeat (issr) loci for resolving relationships in the canary island species of tolpis (asteraceae).plants of oceanic islands, often remarkably divergent morphologically from continental relatives, are useful models for studying evolution and speciation because evolution is telescoped in time and space. prior studies revealed little dna sequence variation within the clade of ca. 10 canary island species of tolpis, which precluded resolving species relationships. the present study assessed the utility of automated analysis of inter-simple sequence repeat (issr) loci for resolving relationships ...200621642181
analysis by gas chromatography-mass spectrometry of the volatiles from the fruits of ammodaucus leucotrichus subsp. leucotrichus and subsp. nanocarpus grown in north africa and the canary islands, respectively.the volatiles from the fruits of ammodaucus leucotrichus subsp. leucotrichus and subsp. nanocarpus (two endemic species, the first from north africa and the second from the canary islands, spain) were studied by gas chromatography and gas chromatography-mass spectrometry. the major components of the volatiles of subsp. nanocarpus were found to be, beta-pinene (22.2-33.6%), bornyl angelate (20.6-21.8%) and camphor (8.3-11.7%) whereas in the fruits of subsp. leucotrichus, the main constituents wer ...200616472529
quantification of ozone uptake at the stand level in a pinus canariensis forest in tenerife, canary islands: an approach based on sap flow measurements.ozone uptake was studied in a pine forest in tenerife, canary islands, an ecotone with strong seasonal changes in climate. ambient ozone concentration showed a pronounced seasonal course with high concentrations during the dry and warm period and low concentrations during the wet and cold season. ozone uptake by contrast showed no clear seasonal trend. this is because canopy conductance significantly decreased with soil water availability and vapour pressure deficit. mean daily ozone uptake aver ...200616457921
respiratory patterns in oscine birds during normal respiration and song production.in this work we study the generation of respiratory patterns by oscine birds. we present a model capable of generating realistic respiratory patterns, during normal respiration and song production. the model accounts for the interaction between neural nuclei and air sac dynamics. we performed experiments in vivo in order to test the predictions of the model, measuring air sac pressure during song and normal respiration in canaries (serinus canaria).200616906868
the canary in the mind: on the fate of dreams in psychoanalysis and in contemporary culture.dreams have been central in the birth and evolution of psychoanalysis. this paper explores the remarkable story of the relationship between dreams and psychoanalysis as a modern version of the long history of dreams in most healing traditions. but psychoanalysis seems to have turned away from dreams as central inspiration in a way parallel to the general culture's turn away from dreams and the reality of inner life. yet modern postindustrial culture is transfixed by a version of "dream life" in ...200616909221
chloroplast microsatellites reveal colonization and metapopulation dynamics in the canary island pine.chloroplast microsatellites are becoming increasingly popular markers for population genetic studies in plants, but there has been little focus on their potential for demographic inference. in this work the utility of chloroplast microsatellites for the study of population expansions was explored. first, we investigated the power of mismatch distribution analysis and the f(s) test with coalescent simulations of different demographic scenarios. we then applied these methods to empirical data obta ...200616911194
apparent 'sympatric' speciation in ecologically similar herbivorous beetles facilitated by multiple colonizations of an island.coexistence of recently diverged and ecologically similar sister species in complete sympatry represents a particularly compelling case for sympatric speciation. this study investigates the possible sympatric origin of two coexisting bark beetle taxa that utilize the same host plant on the island of la palma in the canary islands. aphanarthrum subglabrum and aphanarthrum glabrum ssp. nudum breed inside dead twigs of euphorbia lamarckii plants and are closely related to the allopatric a. glabrum ...200616911212

[coronary risk in the population of the canary islands, spain, using the framingham function].although ischemic cardiopathy mortality in the canary islands is among the highest in spain, the specific coronary risk for its population has not been estimated. this study presents the first cardiovascular risk charts for the canarian adult population and compares them with those previously published on gerona, spain.200616756902
[christopher columbus flu. a hypothesis for an ecological catastrophe].when christopher columbus and his men embarked on the second colombian expedition to the new world (1493), the crew suffered from fever, respiratory symptoms and malaise. it is generally accepted that the disease was influenza. pigs, horses and hens acquired in gomera (canary islands) traveled in the same ship. the pigs may well have been the origin of the flu and the intermediary hosts for genetic recombination of other viral subtypes. the caribbean archipelago had a large population of birds, ...200616762260
the "canary incident" in w.c. field's 1928 earl carroll's vanities stage dental skit.w.c. fields (1880-1946), a gifted writer, director and performer, became one of the greatest comedians, jugglers and pantomimes of all time. this crusty, opinionated curmudgeon, whose multifaceted career spanned most of the 20th century, made his name in burlesque, vaudeville, the legitimate stage, silent pictures, talkies, radio, books and recordings. 1-3 he died before a new media -- television - could have brought him even more success. the following article explores a fascinating incident wh ...200616764237
explaining sex differences in dental caries prevalence: saliva, hormones, and "life-history" etiologies.when dental caries rates are reported by sex, females are typically found to exhibit higher prevalence rates than males. this finding is generally true for diverse cultures with different subsistence systems and for a wide range of chronological periods. exceptions exist, but are not common. in this paper, we present new data for sex differences in dental caries rates among the guanches (tenerife, canary islands), summarize results of meta-analyses of dental caries prevalence, and emphasize new ...200616788889

randomized clinical trial of telepsychiatry through videoconference versus face-to-face conventional psychiatric treatment.although telepsychiatry in the form of videoconferencing has been well received in terms of increasing access to care and user satisfaction, few data on treatment outcomes and efficacy from telepsychiatry applications are available at the present time. this paper evaluates the efficacy of telepsychiatry through videoconference in the treatment of mental disorders by comparing to face-to-face conventional (f2fc) treatment. we carried out a randomized clinical trial where 140 psychiatric outpatien ...200616796502
seroprevalence of canine heartworm disease (dirofilaria immitis) on tenerife island: an epidemiological update.blood samples from 823 dogs were tested for circulating dirofilaria immitis antigen during a 1-year period (may 2002 to may 2003) on tenerife island, canary islands, spain. seroprevalence of heartworm infection was 21%. heartworm infection was similar in males and females and was more common in dogs aged >6 years. distribution of infection in varying climatic zones was not statistically different.200616821033
social context affects testosterone-induced singing and the volume of song control nuclei in male canaries (serinus canaria).the contribution of social factors to seasonal plasticity in singing behavior and forebrain nuclei controlling song, and their interplay with gonadal steroid hormones are still poorly understood. in many songbird species, testosterone (t) enhances singing behavior but elevated plasma t concentrations are not absolutely required for singing to occur. singing is generally produced either to defend a territory or to attract a mate and it is therefore not surprising that singing rate can be influenc ...200616838373
molecular evidence for adaptive radiation of micromeria benth. (lamiaceae) on the canary islands as inferred from chloroplast and nuclear dna sequences and issr fingerprint data.the canary islands have been a focus for phylogeographic studies on the colonization and diversification of endemic angiosperm taxa. based on phylogeographic patterns, both inter island colonization and adaptive radiation seem to be the driving forces for speciation in most taxa. here, we investigated the diversification of micromeria on the canary islands and madeira at the inter- and infraspecific level using inter simple sequence repeat pcr (issr), the trnk-intron and the trnt-trnl-spacer of ...200616839782
