Other effective area‐based conservation measures (OECMs) are sites that deliver effective biodiversity outcomes irrespective of their management objectives. These areas are widely expected to play an important role in efforts to protect 30% of Earth by 2030. Despite general guidance to support screening sites against the formal criteria to be OECMs, progress recognizing sites has been limited. To advance the ability to identif...

Improved quantification techniques of natural sources are needed to explain variations in atmospheric methane. In polar regions, high uncertainties in current estimates of methane release from the seabed remain. We present unique 10- and 3-month time series of bottom water measurements of physical and chemical parameters from two autonomous ocean observatories deployed at separate intense seabed methane seep sites (91 and 246...

Zusammenfassung Untersuchungen zu Bewegungsanteilen im Sportunterricht unter Verwendung objektiver Verfahren sind in Deutschland selten. Sie sind jedoch sowohl aus gesundheits- und trainingswissenschaftlicher als auch aus sportpädagogischer Perspektive von Interesse, um Schulsportwirklichkeit systematisch analysieren zu können. Der vorliegende Beitrag untersucht Bewegungszeit (Minuten), Belastungsintensität (Herzschläge pro Mi...

There is a need for cost-efficient tools to explore deep-ocean ecosystems to collect baseline biological observations on pelagic fauna (zooplankton and nekton) and establish the vertical ecological zonation in the deep sea. The Pelagic In situ Observation System (PELAGIOS) is a 3000 m rated slowly (0.5 m s−1) towed camera system with LED illumination, an integrated oceanographic sensor set (CTD-O2) and telemetry allowing for o...

The IUCN Red List is the most extensive source of conservation status assessments for species worldwide, but important gaps in coverage remain. Here, we demonstrate the use of a spatial prioritization approach to efficiently prioritize species assessments to achieve increased and up‐to‐date coverage efficiently. We focus on freshwater fishes, which constitute a significant portion of vertebrate diversity, although comprehensiv...

Large quantities of the greenhouse gas methane (CH 4 ) are stored in the seafloor. The flux of CH 4 from the sediments into the water column and finally to the atmosphere is mitigated by a series of microbial methanotrophic filter systems of unknown efficiency at highly active CH 4 ‐release sites in shallow marine settings. Here, we studied CH 4 ‐oxidation and the methanotrophic community at a high‐CH 4 ‐flux site in the north...

Studies of the trophic structure in methane‐seep habitats provide insight into the ecological function of deep‐sea ecosystems. Methane seep biota on the Chilean margin likely represent a novel biogeographic province; however, little is known about the ecology of the seep fauna and particularly their trophic support. The present study, using natural abundance stable isotopes, reveals a complex trophic structure among heterotrop...

During the discovery and description of seven New Zealand methane seep sites, an infaunal assemblage dominated by ampharetid polychaetes was found in association with high seabed methane emission. This ampharetid‐bed assemblage had a mean density of 57,000 ± 7800 macrofaunal individuals m −2 and a maximum wet biomass of 274 g m −2 , both being among the greatest recorded from deep‐sea methane seeps. We investigated these quest...
