Kreislauf zwischen Aufnahme von Schwefelbakterien in Larven der Riesenröhrenwürmer und Verlassen des toten Wirts entschlüsselt

Hydrothermale Quellen in Vulkankratern der Tiefsee sind schnell vergänglich. Am ostpazifischen Rücken entstehen und versiegen solche Quellen innerhalb weniger Jahre. Riesenröhrenwürmer finden neue Quellen extrem schnell, wachsen innerhalb eines Jahres mehr als einen Meter und sterben wenige Jahre danach. Dieses Schicksal teilen sie aber nicht mit ihren bakteriellen Symbionten, die tief im Inneren des Wirtskörpers leben. Wie ein internationales ForscherInnenteam unter der Leitung der Meeresbiologin Monika Bright von der Universität Wien entdeckte, verlassen die Schwefelbakterien ihren toten Wirt und vermehren sich im Freien. Die Ergebnisse dazu erscheinen aktuell in der Fachzeitschrift “Proceedings of the National Academy of Science”. (more…)

Woods Hole Oceanographic Institution’s ‘Dive and Discover’ Begins Jan. 2, 2014

Scientists and engineers using advanced technology and a unique robotic vehicle to study the deep sea will also be using their computers to interact with students, teachers, and the public about the research they are conducting.

Working along the East Pacific Rise, a mid-ocean ridge about 600 miles south of Manzanillo, Mexico, aboard the research vessel Atlantis, scientists from Woods Hole Oceanographic Institution (WHOI) and their colleagues will examine life in some of the most extreme environments on Earth—deep-sea hydrothermal vents.

Studying phages, viruses that infect bacteria, can help researchers to better understand how portions of the world’s oceans function without oxygen.

Though small, viruses could hold the secrets of how vast portions of the world’s oceans function without oxygen.

University of Arizona undergraduate researcher Sarah Schwenck and postdoctoral associate Jennifer Brum are conducting a research project in the Tucson Marine Phage Lab, which is headed by assistant professor of ecology and evolutionary biology Matthew Sullivan. (more…)
