| 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 ... | 2006 | 21646225 |
| 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 ... | 2006 | 21642146 |
| 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 ... | 2006 | 21642194 |
| 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 ... | 2006 | 21642177 |
| 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). | 2006 | 16906868 |
| 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 ... | 2006 | 16909221 |
| 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 ... | 2006 | 16911194 |
| 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 ... | 2006 | 16911212 |
| nonlinear model predicts diverse respiratory patterns of birdsong. | a central aspect of the motor control of birdsong production is the capacity to generate diverse respiratory rhythms, which determine the coarse temporal pattern of song. the neural mechanisms that underlie this diversity of respiratory gestures and the resulting acoustic syllables are largely unknown. we show that the respiratory patterns of the highly complex and variable temporal organization of song in the canary (serinus canaria) can be generated as solutions of a simple model describing th ... | 2006 | 16486997 |
| qualitative inheritance of rind pattern and flesh color in watermelon. | watermelon [citrullus lanatus (thunb.) matsum. & nakai var. lanatus] is a diverse species, with fruits of different sizes, shapes, rind patterns, and flesh colors. this study measured the inheritance of novel rind phenotypes and verified the genetics of white, red, salmon yellow, and canary yellow flesh colors. for each of the 11 crosses, six generations (p(a)s1, p(b)s1, f1, f2, bc1p(a), and bc1p(b)) were produced to form 11 families. three new genes were identified and designated as follows: sc ... | 2006 | 16489140 |

| [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, ... | 2006 | 16762260 |
| 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 ... | 2006 | 16764237 |
| 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 ... | 2006 | 16788889 |

| 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 ... | 2006 | 16796502 |
| 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. | 2006 | 16821033 |
| 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 ... | 2006 | 16838373 |
| 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 ... | 2006 | 16839782 |
