LABSIM: A data-driven simulation program for instruction in research design and statistics

Abstract: LABSIM is a general-purpose FORTRAN program that simulates the collection of data from laboratory experiments. Student-specified parameters are employed in a multiple-regression model that allows manipulation or control of up to 10 potential independent variables. Variables may be discrete (up to eight levels), continuous, or range (e.g., IQ). Raw scores may be generated for up to six groups, optionally accompanied by statistical analyses for simple between- or within-subjects designs or for factorial designs, including mixed factorial designs. Seventeen models (content areas) are currently available. As contrasted with other simulation programs, LABSIM models are exceptionally easy to design and implement; no computer expertise is required. Summary data automatically collected by LABSIM indicate a high success rate and extensive use of the program beyond course requirements. The current version of LABSIM is available in either batch or interactive form. A newer version that allows the simultaneous manipulation of up to three independent variables will be available soon.

Molecular analysis of the xylFGH operon, coding for xylose ABC transport, in Thermoanaerobacter ethanolicus.

Abstract: A xylose ABC (ATP-binding cassette) transport operon, xylFGH, was cloned from Thermoanaerobacter ethanolicus, a thermophilic ethanol-producing eubacterium. The cistrons code for a periplasmic D-xylose-binding protein (XylF, partial sequence of 250 amino acids), ATP-binding protein (XylG, 505 amino acids), and integral membrane protein (XylH, 388 amino acids). These results, together with previous work, indicate that duplicate copies of both xylF and xylH are present in the T. ethanolicus chromosome, suggesting ancient gene duplication or lateral gene transfer events. XylG resembles other eubacterial monosaccharide ABC-ATPases in that its two nucleotide-binding domains (NBDs) are highly homologous, yet significantly different with respect to putative catalytic residues. Unlike most other integral membrane ABC transport proteins, XylH apparently contains 11 or 12 transmembrane segments (TMS) and is similar to a small group of ABC permeases that defy the “2 × 6” helix paradigm. This is the first report of a monosaccharide ABC transport operon in a thermophilic anaerobic eubacterium.

Social change at the Harappan settlement of Gola Dhoro: a reading from animal bones

Abstract: Detailed analysis of the animal bone assemblage at Gola Dhoro here throws light on the expansion of the Indus civilisation into Gujarat. A square fort, imposed on a settlement of livestock herders in the later third millennium BC, was shown to have contained people who introduced a broader diet of meat and seafood, and new ways of preparing it. These social and dietary changes were coincident with a surge in craft and trade.

Pan-regional marine benthic cryptobiome biodiversity patterns revealed by metabarcoding Autonomous Reef Monitoring Structures.

Abstract: Autonomous Reef Monitoring Structures (ARMS) have been applied worldwide to characterize the critical yet frequently overlooked biodiversity patterns of marine benthic organisms. In order to disentangle the relevance of environmental factors in benthic patterns, here, through standardized metabarcoding protocols, we analyse sessile and mobile (<2 mm) organisms collected using ARMS deployed across six regions with different environmental conditions (3 sites × 3 replicates per region): Baltic, Western Mediterranean, Adriatic, Black and Red Seas, and the Bay of Biscay. A total of 27,473 Amplicon Sequence Variants (ASVs) were observed ranging from 1,404 in the Black Sea to 9,958 in the Red Sea. No ASVs were shared among all regions. The highest number of shared ASVs was between the Western Mediterranean and the Adriatic Sea (116) and Bay of Biscay (115). Relatively high numbers of ASVs (103), mostly associated with the genus Amphibalanus, were also shared between the lower salinity seas (Baltic and Black Seas). We found that compositional differences in spatial patterns of rocky-shore benthos are determined slightly more by dispersal limitation than environmental filtering. Dispersal limitation was similar between sessile and mobile groups, while the sessile group had a larger environmental niche breadth than the mobile group. Further, our study can provide a foundation for future evaluations of biodiversity patterns in the cryptobiome, which can contribute up to 70% of the local biodiversity.
