Seed-filled buoys may help restore diverse sea meadows in San Francisco Bay

Seed-filled buoys may help restore diverse sea meadows in San Francisco Bay

  Mesocosm tanks at the Romberg Tiburon Center were used for experiments on genetic diversity in eelgrass restoration. Pearl nets filled with seedpods were dropped into the tanks, where the seeds germinated and eventually grew into large plants, seen above.

Недавно обнаруженный микроб способствует глобальному потеплению климата

Недавно обнаруженный микроб способствует глобальному потеплению климата

Ученые из университета Квинсленда, Австралия, недавно обнаружили микроб, который может сыграть важную роль в глобальном потеплении климата. Этот микроб представляет собой метан-продуцирующий микроорганизм, известный как «метаноген», находится в приповерхностном слое почвы в районах пожизненной мерзлоты на севере Швеции, и по мере оттаивания почвы, он начинает расти и развиваться, выпуская газ метан и тем самым способствуя […]

Masura istorica luata de autoritatile chineze din cauza poluarii

Masura istorica luata de autoritatile chineze din cauza poluarii

  Autoritatile chineze au luat o masura istorica, din cauza poluarii din capitala Beijing, fiind emisa prima alerta cod portocaliu de poluare din istoria tarii. Locuitorii orasului au fost avertizati astfel ca Beijingul va fi acoperit, in urmatoarele trei zile, de un strat gros de smog, scrie site-ul Descrier. Autoritatile au fost criticate tocmai din […]

Legal harvest of marine turtles tops 42,000 each year

Legal harvest of marine turtles tops 42,000 each year

  The first marine turtle harvest legislation was instigated in Bermuda in 1620 to protect «so excellent a fish» and prohibited taking any turtle «under 18 inches in the breadth or diameter.» A new study has found that 42 countries or territories around the world permit the harvest of marine turtles — and estimates that […]

Forest model predicts canopy competition: Airborne lasers help researchers understand tree growth

    This is professor Jim Kellner in a Hawaiian forest. He and colleague Gregory Asner worked out a model to predict the likelihood that one a tree limb could be overtopped amid competiton for space in the canopy.

Cum arata cel mai poluat loc din Hunedoara. Proiectul de ecologizare a ruinelor combinatului intarzie

Cum arata cel mai poluat loc din Hunedoara. Proiectul de ecologizare a ruinelor combinatului intarzie

Administratia locala a inceput in 2010 demersurile pentru ecologizarea a 20 de hectare din vechea platforma industriala a municipiului Hunedoara. Valoarea proiectului „Reabilitarea sitului industrial si pregatirea lui pentru alte activitati” a fost estimata la peste 60 de milioane de lei, cea mai mare parte a fondurilor fiind reprezentata de contributia Uniunii Europene. In luna mai […]

В долине Темзы паводковые воды сильно загрязнены опасными бактериями

В долине Темзы паводковые воды сильно загрязнены опасными бактериями

Высокие уровни фекального загрязнения, в том числе опасных болезнетворных бактерий, были отысканы в паводковых водах в деревне Рейнсбери, расположенной в долине Темзы. Микробиолог доктор Бен Ньюман из Беркширского университета обнаружил, что в каждых 100 миллилитрах воды в этом районе содержится до 100 тысяч бактерий, в том числе кишечной палочки, тогда как разрешенные Всемирной организацией здравоохранения […]

Temperature and ecology: Rival Chilean barnacles keep competition cool

Temperature and ecology: Rival Chilean barnacles keep competition cool

      In Chile, it’s not always about the temperature — Barnacle species had been thought to sort themselves vertically by temperature; species that prefer warmer, drier conditions living higher on the rocks than species that prefer a colder, wetter setting. Experiments in Chile show that temperature “wasn’t the beast.” Credit: Image courtesy of […]

O suta de tone de apa contaminata radioactiv s-au scurs la Fukushima

O suta de tone de apa contaminata radioactiv s-au scurs la Fukushima

Operatorul centralei nucleare dezafectate de la Fukushima anunta ca o cantitate de 100 de tone de apa radioactiva s-a scurs, zilele trecute, dintr-un rezervor al facilitatii afectate de valul seismic din martie 2010. „Locul se afla departe de ocean si nu credem ca scurgerile au ajuns in Pacific“, a declarat Masayuki Ono, purtator de cuvant […]
