Visualization of adiabatic gas-liquid flow in a cross-corrugated plate heat exchanger channel: Part 1 - Original photographs, uniform two-phase distribution

These measurement data are obtained and analyzed as part of a research project on adiabatic gas-liquid flow in a cross-corrugated plate heat exchanger channel. (See list of publications below).  The following Creative Commons license applies to the research data (images and measurement values) uploaded to the online repositories: CC-BY 4.0 Author: Susanne Buscher The measurement data is published in 2 data sets:   Data set I: Original image data (4 parts):      - uniform gas injection, part 1: https://doi.org/10.5281/zenodo.7985771;      - uniform gas injection, part 2: https://doi.org/10.5281/zenodo.7986374;      - uniform gas injection, part 3: https://doi.org/10.5281/zenodo.7986384;      - non-uniform gas injection (part 4): https://doi.org/10.5281/zenodo.8067163 This data set contains the original photographs of the two-phase flow in the cross-corrugated channel obtained with a high-resolution camera. In addition, the corresponding experimental parameters and flow patterns (for part 1-3 only) are included in the CSV files. For uniform and non-uniform gas injection, respectively, the images were stored in sequentially numbered folders. The numbers of the folders correspond to the numbers of the measurement points listed in the attached CSV files with the associated experimental parameters. The image folders are grouped in ZIP archives. Each ZIP archive contains the single-phase reference images which can be used for the two-phase images to conduct background subtraction, because the lighting conditions are equal for all images in one ZIP archive.  Data set II: Measurement values and processed image data:      - https://doi.org/10.14279/depositonce-17868;  This data set contains all measurement values and calculated results of all measurement points in the Excel and CSV files (e.g. pressure drop, volumetric flow rates, void fraction, measurement uncertainties). In addition, the results of the image processing algorithm are included in the Excel and CSV files (e.g. mean bubble diameter, maximum bubble diameter, local film flow ratio, extent of the two-phase distribution across the channel width, measurement uncertainties). The image folders contain the pre-processed images which were the input to the digital image analysis (i.e. the aligned and cropped image section of the channel without inlet, outlet, and peripheral regions and after subtraction of the image background), and the post-processed images visualizing the output of the digital image analysis for this image (i.e. detected objects are inserted as colored regions in the image section; the meaning of colors was explained in the publications of 2022 and 2023).  In this dataset, the image folders are also subdivided into measurements with uniform and non-uniform gas injection and designated with the numbers of the measurement points, which are listed in the Excel and CSV files. The two datasets are the supplementary research data for the following publications:  - S.

Photographic documentation of forestry treatments of 77 forest plots at Sagehen Creek Field Station, 2016-2019

Data package contains sets of photographs taken at 77 forest monitoring plots within the Sagehen Experimental Forest. These plots are a subset of 500+ forest monitoring plots established in 2004 and 2005 for the purpose of testing strategically-placed land area treatments (SPLATS) that impede forest fire progression (Vaillant 2008, UC Berkeley Doctoral Dissertation). Sites were photographed at various intervals before and after prescribed forestry treatments. Two major types of treatment occurred and additional activity is ongoing. In Summer/Fall 2016, hand thinning or mastication was performed on a subset of plots, and in Summer/Fall 2018, logging was performed on another subset of plots. Some plots received one treatment, and others received none. Information about photo dates and treatment status can be found in the FMP details csv file. This monitoring is ongoing through the Sagehen Forest Project.

Annual ground-based photographs taken at 15 net primary production (NPP) study sites at Jornada Basin LTER, 1996-ongoing

This data package contains a list of ground-based photographs taken at fifteen Net Primary Production (NPP) study sites at the Jornada Basin LTER. Sites were selected to represent the 5 major ecosystem types in the Chihuahuan Desert (upland grasslands, playa grasslands, mesquite-dominated shrublands, creosotebush-dominated shrublands, tarbush-dominated shrublands). For each ecosystem type, three sites were selected to represent the range in variability in production and plant diversity; thus the locations are not replicates. At each site, a 1 hectare area was fenced in 1988 and a grid of 49 (48 at one playa location) 1m x 1m replicate quadrats was laid out when vegetation sampling began in 1989. Beginning in 1996, annual photos were taken from each of the 4 corners of each of the 15 70-meter x 70-meter NPP sites between August and November, depending on other research activity constraints. From 1996-2002 photos were taken using 35mm color slide film. Beginning in 2003, digital photos were taken in JPG format. Occasionally, supplemental photos may be taken at the same time that provide additional habitat information at the landscape, patch, or plant species level. No photographs were taken in 2013. Photo files (.jpeg format) are included in annual ZIP archives attached to this data package. This is an ongoing dataset that is updated once per year.

Vermivora photographs in plumage genomic study

Hybrids with different combinations of traits can be used to identify the genomic regions that underlie phenotypic characters important to species identity and recognition. Here we explore links between genomic and plumage variation in Blue-winged Warbler x Golden-winged Warbler hybrids, which have traditionally been categorized into two discrete types. "Lawrence's Warbler" hybrids are very yellow overall, similar to Blue-winged Warblers, but exhibit the black throat patch and face mask of Golden-winged Warblers. "Brewster's Warbler" hybrids are similar to Golden-winged Warblers, but lack the black throat patch and face mask and sometimes have yellow on their underparts. Previous studies hypothesized that (1) first generation hybrids are of the Brewster's type and can be distinguished by the amount of yellow on their underparts, and that (2) the throat patch/mask phenotype is consistent with Mendelian inheritance and controlled by variation in a locus near the Agouti signaling protein gene (ASIP). We addressed these hypotheses using whole genome re-sequencing of parental and hybrid individuals. We found that Brewster's hybrids had genomic hybrid index scores that indicate this phenotype can arise by majority ancestry from either parental species, their plumage varied from low-to-high levels of carotenoid pigmentation, and individuals captured in multiple years grew consistently less yellow as they aged. Variation in carotenoid pigmentation showed little relationship with genomic hybrid index and is thus inconsistent with previous hypotheses that first generation hybrids can be distinguished by the amount of yellow in their plumage. Our results also confirm that variation near ASIP underlies the throat patch phenotype, which we refined to a ~10-15 Kb region upstream of the coding sequence. Overall, our results support the notion that traditional categorization of hybrids as either Lawrence's or Brewster's over-simplifies their genomic and continuous variation in carotenoid pigmentation and is based primarily on one discrete trait, which is the throat patch/mask phenotype.

Mountain goat molt from community photographs

Participatory approaches, such as community photography, can engage the public in questions of societal and scientific interest while helping advance understanding of ecological patterns and processes. We combined data extracted from community-sourced, spatially-explicit photographs with research findings from 2018 fieldwork in the Yukon, Canada, to evaluate winter coat molt patterns and phenology in mountain goats (Oreamnos americanus), a cold-adapted, alpine mammal. Leveraging the community science portals iNaturalist and CitSci, in less than a year we amassed a database of almost seven hundred unique photographs spanning some 4500 kms between latitudes 37.6°N and 61.1°N from 0m to 4333m elevation. Using statistical methods accounting for incomplete data, a common issue in community science data sets, we identified the effects of intrinsic (sex and presence of offspring) and broad environmental (latitude and elevation) factors on molt onset and rate and compared our findings with published data. Shedding occurred over a 3-month period between May 29 and September 6. Effects of sex and offspring on the timing of molt were consistent between the community-sourced and our Yukon data and with findings on wild mountain goats at a long-term research site in west-central Alberta, Canada. Males molted first, followed by females without offspring (4.4 days later in the coarse-grained, geographically-wide community science sample; 29.2 days later in our fine-grained Yukon sample) and lastly females with new kids (6.2; 21.2 days later, respectively). Shedding was later at higher elevations and faster at northern latitudes. Our findings establish a basis for employing community photography to examine broad-scale questions about the timing of ecological events, as well as sex differences in response to possible climate drivers. In addition, community photography can help inspire public participation in environmental and outdoor activities specifically with reference to iconic wildlife.

When waterholes get busy, rare interactions thrive: Photographic evidence of a jaguar (Panthera onca) killing an ocelot (Leopardus pardalis)

During a camera trap survey conducted in Guatemala in the 2019 dry season, we documented a jaguar killing an ocelot at a waterhole with high mammal activity. During severe droughts, the probability of aggressive interactions between carnivores might increase when fixed, valuable resources such as water cannot be easily partitioned.

Data from: Continent‐scale phenotype mapping using citizen scientists' photographs

Field investigations of phenotypic variation in free‐living organisms are often limited in scope owing to time and funding constraints. By collaborating with online communities of amateur naturalists, investigators can greatly increase the amount and diversity of phenotypic data in their analyses while simultaneously engaging with a public audience. Here, we present a method for quantifying phenotypes of individual organisms in citizen scientists' photographs. We then show that our protocol for measuring wing phenotypes from photographs yields accurate measurements in two species of Calopterygid damselflies. Next, we show that, while most observations of our target species were made by members of the large and established community of amateur naturalists at iNaturalist.org, our efforts to increase recruitment through various outreach initiatives were successful. Finally, we present results from two case studies: (1) an analysis of wing pigmentation in male smoky rubyspots (Hetaerina titia) showing previously undocumented geographical variation in a seasonal polyphenism, and (2) an analysis of variation in the relative size of the wing spots of male banded demoiselles (Calopteryx splendens) in Great Britain questioning previously documented evidence for character displacement. Our results demonstrate that our protocol can be used to create high quality phenotypic datasets using citizen scientists' photographs, and, when combined with metadata (e.g., date and location), can greatly broaden the scope of studies of geographical and temporal variation in phenotypes. Our analyses of the recruitment and engagement process also demonstrate that collaborating with an online community of amateur naturalists can be a powerful way to conduct hypothesis‐driven research aiming to elucidate the processes that impact trait evolution at landscape scales.
