TL;DR: Hamburg Registration and Organization Online Tool (Hroot) as discussed by the authors is a web-based software designed for managing participants of economic experiments, which provides important features to assure a randomized invitation process based on a filtered, pre-specified subject pool.

TL;DR: Strong perceptual correlates support their functional relevance: the strength of synchronization within these networks predicted the subjects' perception of an ambiguous audiovisual stimulus as well as the integration of auditory and visual information.

TL;DR: This map reveals that the global number of trees is approximately 3.04 trillion, an order of magnitude higher than the previous estimate, and the globalNumber of trees has fallen by approximately 46% since the start of human civilization.
Abstract: The global extent and distribution of forest trees is central to our understanding of the terrestrial biosphere. We provide the first spatially continuous map of forest tree density at a global scale. This map reveals that the global number of trees is approximately 3.04 trillion, an order of magnitude higher than the previous estimate. Of these trees, approximately 1.39 trillion exist in tropical and subtropical forests, with 0.74 trillion in boreal regions and 0.61 trillion in temperate regions. Biome-level trends in tree density demonstrate the importance of climate and topography in controlling local tree densities at finer scales, as well as the overwhelming effect of humans across most of the world. Based on our projected tree densities, we estimate that over 15 billion trees are cut down each year, and the global number of trees has fallen by approximately 46% since the start of human civilization.

TL;DR: In this article, a review of biogeochemical processes at ancient methane-seeps is presented, focusing on carbonate fabrics and phases, including inverted stromatactoid cavities, globular fabrics, botryoidal aragonite, micritic nodules, fractures, clotted micrites, and constructive seams representing fossilised biofilms.

TL;DR: A 16S rRNA-targeted oligonucleotide probe (NEU) specific for some representatives of the lithoautotrophic ammonia-oxidizing bacteria was developed based on comparative sequence analysis and showed promise in detecting dense cell clusters exclusively in those samples originating from sewage treatment plants with stable nitrification.
