Significant changes in the bacterioplankton community structure of a maritime Antarctic freshwater lake following nutrient enrichment

first_imgNutrient enrichment is known to increase bacterioplankton population density in a variety of Antarctic freshwater lakes. However, relatively little is known about the associated changes in species composition. In this study, the bacterioplankton community composition of one such lake was studied following natural nutrient enrichment to investigate the resistance of the system to environmental change. Heywood Lake is an enriched freshwater maritime Antarctic lake, with nitrogen and phosphorus concentrations significantly higher than its more oligotrophic neighbours (by at least an order of magnitude). This major change in lake chemistry has occurred following large increases in the fur seal population over the last 30 years. Using analysis of 16S rRNA gene fragments, fatty acid methyl ester analysis, denaturing gradient gel electrophoresis and fluorescence in situ hybridization, significant changes are reported in lake microbiology which have resulted in a distinct bacterioplankton community. In comparison to its more oligotrophic neighbours, nutrient-enriched Heywood Lake has a high bacterioplankton population density, reduced species richness and an increasing evenness among key groups. Only 42·3 % of the clones found with 97 % similarity to a named genus were also present in adjacent oligotrophic lakes, including three of the dominant groups. Critically, there was an apparent shift in dominance with trophic status (from the -Proteobacteria to the Actinobacteria). Other key observations included the absence of a dominant group of Cyanobacteria and the presence of marine bacteria. The significant impact of natural nutrient enrichment on the microbiology of Heywood Lake, therefore, suggests that low-temperature oligotrophic freshwater lake systems might have low resistance to environmental change.last_img read more

Papuan People’s Assembly entrusts safety of Papuan students to Jember regent

first_img“We are victims of racism. The government must talk about it seriously. We want a solution,” Eko Pilipus Kogoya, one of the migrant students who moved back to Papua, told the Post.In response to the message, Jember Regent Faida said she promised to take care of the Papuan people in her regency.“We promise to protect the bright generation who will develop Papua in the future,” she said in a statement released by the MRP.Last year, racial abuse incidents against Papuan students living in Malang and Surabaya, East Java, triggered widespread and prolonged protests, some turning violent, in Papua and West Papua. Topics : During a meeting about the fate of Papuan migrant students after last year’s racial abuse incidents in East Java, the Papuan People’s Assembly (MRP) asked Jember Regent Faida to ensure the safety of the Papuan students in her regency.MRP chairman Timotius Murib said during the meeting that took place at the office of the special representatives for indigenous Papuans on Jan. 27 he had asked the regent to take care of the Papuan student community currently in Jember.“We left a message [for Faida] to protect the Papuan people, especially the 200 students who are studying in Jember,” he told The Jakarta Post. Timotius said that he relayed the message on behalf of the students’ parents, with the hope that there would be security guarantees for students in Jember.“We communicated the message so that [the students] can be [treated] like the regent’s children, as well as the Forkopimda’s [Regional Leadership Communication Forum] children and the people of Jember’s children,” he said.The meeting with the regent was a follow-up to a discussion with Papuan migrant students the week before, during which the students asked the MRP, the Papuan Regional Legislative Council (DPRD) and the Papua Governor to pay more attention to their future, Timotius said.He said that many Papuan students who were studying in different cities outside the region have returned to Papua because they felt unsafe in their cities of study.last_img read more

Ex-EPL star cheats death after gunshot attack

first_img Loading… The La Liga side published a message on its Twitter which said: “We are hearing worrying news from Athens. “Darko, we wish you a swift recovery.” It was not immediately clear this morning why Kovacevic had been targeted.

No arrests are thought to have taken place. Kovacevic represented Yugoslavia at the 1998 World Cup and Euro 2000. FacebookTwitterWhatsAppEmail分享 center_img Ex-Sheffield Wednesday forward Darko Kovacevic has cheated death after being shot at outside his home in Athens. The retired Serbian international was attacked by two men who ambushed him as he went to park his car. One assailant fired a shot at the 46-year-old. He was taken to hospital for wrist and knee injuries after reportedly hurting himself as he fell to the ground to dodge the bullet. The getaway vehicle the criminals fled in, a Smart car, was found burnt out near the scene of the attack in the neighbourhood of Glyfada to the south of Athens city centre. Kovacevic managed only four goals in his half-season at Sheffield Wednesday in 1996 before going on to make a name for himself at Spanish side Real Sociedad. He told local press after being released from hospital: “I saw a man getting out of a car with a gun in his hand and coming towards me. “I instinctively dived to the right and he fired at me. “Then he ran, got into the car and disappeared.” Real Sociedad, where Kovacevic regained his reputation as one of Europe’s best players after his poor showing at Sheffield Wednesday, were among the clubs offering the striker their support today.last_img read more
