RAMP data subset, January 1 through May 31, 2019
<p>The data are a subset of data from RAMP, the Repository Analytics and Metrics Portal (<a href="http://ramp.montana.edu/">http://ramp.montana.edu/</a>), consisting of data from 35 (out of 50) participating institutional repositories (IR) from the period of January 1 through May 31, 2019. This subset represents data analyzed for a pending publication. For a description of the data collection, processing, and output methods, please see the "methods" section below.</p> <p>The 'RAMP Primer,' a Jupyter Notebook consisting of Python code for combining monthly data and generating some aggregate statistics is available from <a href="https://github.com/imls-measuring-up/ramp-documentation.git">https://github.com/imls-measuring-up/ramp-documentation.git</a>. The linked repository also includes data documentation similar to that provided in the "methods" section below, as well as a file of IR index names useful for subsetting and filtering the data.</p> <p><b>Update: </b>Version two of this dataset was uploaded on January 14, 2020. Thanks to RAMP participants, the RAMP administrators discovered an error in the daily data harvest that resulted in incomplete page-click data for roughly 15 RAMP participating repositories. Only page-click data as described below were affected, and the corrsponding CSV files have been replaced with corrected data. The country-device data were not affected and have not been changed from version 1.</p>

Testing the reliability and ecological implications of ramping rates in the measurement of Critical Thermal maximum
<p>C<span>ritical Thermal maximum (CTmax) is often used to characterize the upper thermal limits of organisms and represents a key trait for evaluating the fitness of ectotherms. The lack of standardization in CTmax assays has, however, introduced methodological problems in its measurement, which can lead to questionable estimates of species' upper thermal limits. Focusing on ants, which are model organisms for research on thermal ecology, we aim to obtain a </span><span>reliable ramping rate that will yield the most rigorous measures of CTmax for the most species. </span><span>After </span><span>identifying three commonly used ramping rates (i.e., 0.2, 0.5 and 1.0 °C min<sup>-1</sup>) in the literature, we experimentally determine their effects on the CTmax values of 27 species measured using dynamic assays. Next, we use static assays to evaluate the accuracy of these values in function of the time of exposure.</span></p> <p><span> Finally, we use field observations of species' foraging activities across a wide range of ground temperatures to identify the most biologically relevant CTmax values and to develop a standardized method. Our results demonstrate that the use of a 1 °C min<sup>-1</sup> ramping rate in dynamic assays yields the most reliable CTmax values for comparing ant species' upper thermal limits, which are further validated in static assays and field observations. We further illustrate how methodological biases in physiological trait measurements can affect subsequent analyses and conclusions on community comparisons between strata and habitats, and the detection of phylogenetic signal </span><span>(</span><span>Pagel's λ and Bloomberg's K</span><span>)</span><span>.</span></p> <p><span>Overall, our study presents a methodological framework for identifying a reliable and standardized ramping rate to measure CTmax in ants, which can be applied to other ectotherms. Particular attention should be given to CTmax values obtained with less suitable ramping rates, and the potential biases they may introduce to </span><span>trait-based research on global warming and habitat conversion, as well as</span> <span>inferences about phylogenetic conservatism</span><span>.</span></p>
Ramped Pyrolysis/Oxidation (RPO) Database
<p>The Ramped-temperature Pyrolysis/Oxidation (RPO) database contains all published RPO raw data, including both thermograms and isotope (<sup>13</sup>C and <sup>14</sup>C) results, where available. All samples are described in the "sample_metadata.csv" file, and all results are presented in the `thermogram` and `isotope` sub-folders. Results are presented as ".csv" files in NOSAMS RPO lab-view format.</p> <p> </p> <p>This database was compiled by Jordon D.

ramp-pulse-zebrafish-heart
<p><strong>Description</strong></p> <p>This dataset contains the raw data used in publication [1]. It features image series of the beating heart of a 48 hours post fertilization old Tg(actb2:LIFEACT-RFP) [2] transgenic zebrafish. Tg(actb2:LIFEACT-RFP) express red fluorescent proteins that bind to F-actin fibers. The images were acquired on an OpenSPIM microscope with an UMPLFLN 20XW semi-apochromat water dipping objective lens. The temporal illumination pattern alternated between ramp-illumination and pulse-illumination for each of the 100 frames of the series (ramp, pulse, ramp, pulse, etc., see [1]). The camera exposure time of each frame was 70ms, the pulse duration was 4ms (see [1] for details on the ramp characteristics).</p> <p> </p> <p><strong>References</strong></p> <p>[1] O. Mariani, F.
