Citation: Mukerji Househam A and Josipovic Z (2015) Commentary: Meditation Effects within the Hippocampal Complex Revealed by Voxel-Based Morphometric and Cytoarchitectonic Probabilistic Mapping. The discovery of experience-dependent structural plasticity in the adult human brain is, arguably, one of the most significant recent developments in neuroscience (Maguire et al., 2000; Gage, 2002).

Cosmogenic 26Al, 10Be, and 14C dating of fluvial fill terraces in steep canyons of the Colorado Front Range provides a temporal framework for analysing episodic aggradation and incision. Results from Boulder Canyon show that terrace heights above the modern channel (grade) can be divided into: (1) Bull Lake ( 100 ka; 20–15 m above grade); (2) Pinedale (32–10 ka; 15–4 m above grade); and (3) Hol...

Many studies highlight that fish trawling activities cause seafloor erosion, but the assessment of the remobilization of surface sediments and its relocation is still not well documented. These impacts were examined along the flanks and axes of three headless submarine canyons incised on the Barcelona continental margin, where trawling fleets have been operating for decades. Trawled grounds alo...

The German EPER, TNO, Belgium, LandGEM, and Scholl Canyon models for estimating methane production were compared to methane recovery rates for 35 Canadian landfills, assuming that 20% of emissions were not recovered. Two different fractions of degradable organic carbon (DOC(f)) were applied in all models. Most models performed better when the DOC(f) was 0.5 compared to 0.77. The Belgium, Scholl...

The most negative carbon isotope excursion in Earth history is found in carbonate rocks of the Ediacaran Period (635-541 Ma). Known colloquially as the “Shuram” excursion, workers have long noted its broad concordance with the rise of abundant macro-scale fossils in the rock record, collectively known as the “Ediacaran Biota.” Thus, the Shuram excursion has been interpreted by many in the conte...

Smithsonian Contributions to the Marine Sciences, number 4, 32 pages, 17 figures, 1980.—Submarine canyon wall and tributary sequences at three Annot Sandstone localities in the French Maritime Alps record early-stage resedimentation events in proximal sectors of the Tertiary Annot Basin.

The National Park Service funded a study to determine the impact of water released from the Glen Canyon Dam on sandbars downriver through Grand Canyon National Park. The project involved considerable amounts of messy and missing data. Some of the challenges faced and lessons learned during this project are described.

A region of exceptionally high macrofaunal benthic biomass exists in Barrow Canyon, implying a carbon export process that is locally concentrated. Here we offer an explanation for this “hotspot” using shipboard data together with set dynamical equations. Repeat occupations the Distributed Biological Observatory transect Canyon reveal when northward flow strong and density front canyon sharp, pl...

This paper presents a conceptual design for connecting ontological and geospatial knowledge bases so that the system can take advantage of the semantic power of ontologies and data storage/analysis/query power of geospatial systems. The design is based on common-place queries, such as “what is a canyon/route/road” or “where is the canyon/route/road X.”

Video images of 215 adult Gila robusta and 148 endangered Gila cypha were collected from May 1991–October 1992 at eight Colorado River basin localities (seven upper basins and one lower basin). The two species were sympatric at five of these locations; G. robusta was absent at one site, whereas G. cypha was missing at two others. Saggital views of each individual were videotaped and 25 morpholo...
