Culture and Hybridization Experiments on an Ulva Clade Including the Qingdao Strain Blooming in the Yellow Sea

In the summer of 2008, immediately prior to the Beijing Olympics, a massive green tide of the genus Ulva covered the Qingdao coast of the Yellow Sea in China. Based on molecular analyses using the nuclear encoded rDNA internal transcribed spacer (ITS) region, the Qingdao strains dominating the green tide were reported to be included in a single phylogenetic clade, currently regarded as a single species. On the other hand, our detailed phylogenetic analyses of the clade, using a higher resolution DNA marker, suggested that two genetically separate entities could be included within the clade. However, speciation within the Ulva clade has not yet been examined. We examined the occurrence of an intricate speciation within the clade, including the Qingdao strains, via combined studies of culture, hybridization and phylogenetic analysis. The two entities separated by our phylogenetic analyses of the clade were simply distinguished as U. linza and U. prolifera morphologically by the absence or presence of branches in cultured thalli. The inclusion of sexual strains and several asexual strains were found in each taxon. Hybridizations among the sexual strains also supported the separation by a partial gamete incompatibility. The sexually reproducing Qingdao strains crossed with U. prolifera without any reproductive boundary, but a complete reproductive isolation to U. linza occurred by gamete incompatibility. The results demonstrate that the U. prolifera group includes two types of sexual strains distinguishable by crossing affinity to U. linza. Species identification within the Ulva clade requires high resolution DNA markers and/or hybridization experiments and is not possible by reliance on the ITS markers alone

Där två världar möts : Erfarenheter och upplevelser av tillgång till Internet och sociala medier på behandlingshem

Syftet med denna studie är att genom kvalitativa intervjuer beskriva upplevelser och erfarenheter av medierad social interaktion på Internet för klienter på behandlingshem för missbrukare. Vi ville undersöka hur detta påverkar klienternas möjligheter att förändra sina liv, identitetsskapande och sociala relationer. Vi genomförde enskilda intervjuer med tre personer som jobbar på ett behandlingshem där klienterna har fri tillgång till Internet och med en klient på samma behandlingshem, samt gruppintervjuer med sammanlagt sju personer som hade varierande erfarenhet av behandlingshem. Resultatet visar en allmän negativ syn på medierad social interaktion under behandlingstiden. Den största risken som lyfts fram under intervjuerna är att Internet försvårar för klienterna att bryta med missbruksvärlden. Kontakt med vänner och bekanta i missbruksvärlden kan leda till att klienten avbryter sin behandling. Andra risker som vårt resultat visar är att klienterna lätt kan beställa droger på Internet, att man inte fokuserar på behandlingen och att det blir svårare att bygga upp en identitet och gemenskap i den nyktra världen.The purpose of this study is to, by using qualitative interviews, describe experiences of mediated social interaction on the Internet for clients in drug treatment. We wanted to examine how this affects clients' ability to change their lives, their identity and social relations. We conducted individual interviews with three people who work at a treatment center where clients have free access to the Internet and with one client on the same centre, and group interviews with a total of seven people who had varied experience in drugtreatment. The results show a general negative view of mediated social interaction during the treatment. The main risk is that clients need to break their connection to “the addiction world” and the Internet complicates this. Contact with friends and acquaintances in “the addiction world” may lead to the client interrupting his or hers treatment. Other risks that our results show is that clients can easily order drugs on the Internet, that you do not focus on the treatment and it makes it more difficult to build an identity and to be part of a community in the sober world
