Hydrochemical Data from a Tropical Andean Glacierized Catchment: δ18O, electrical conductivity, maximum fluorescence intensity, and dissolved organic carbon concentrations from short-term sampling campaigns, Ecuador (2022 and 2024)
Fluorescent dissolved organic matter (FDOM) quality, dissolved organic carbon (DOC) concentration, electrical conductivity (EC), and stable water isotopes (δ¹⁸O and δ2H) were determined in water, snow, and ice samples from a tropical glacierized catchment in the Ecuadorian Andes. The sampling locations were selected to capture the major hydrologic inputs to the main stream channel (glacial melt, tributaries, wetlands, and groundwater springs) and constrain the in-stream spatiotemporal variation in DOM quality and other hydrochemical characteristics. Two sets of high-resolution time series were collected on Oct 13, 2022 and Jun 14, 2024. Time series samples were collected at various upper catchment locations and the outlet simultaneously. DOM quality was characterized via fluorescence spectroscopy and processed using parallel factor analysis (PARAFAC). The DOM quality data are expressed as %FMax values obtained through a 4-component PARAFAC model, where %Fmax 1– 4 are interpreted as terrestrial humic-like, tyrosine-like, tryptophan-like, and microbial humic-like fluorescent components, respectively. DOC concentrations were quantified using high-temperature catalytic combustion, stable water isotopes were analyzed using laser-based spectroscopy, and EC was measured in situ with handheld multiparameter water quality probes.
Puma diet in a high Andean ecosystem, 2012-2022
We analyzed 45 puma scats collected between 2012 and 2022, identified in the field based on size, shape, and hair content. Scats were dissected, and prey remains (bones, teeth, claws) were soaked in soapy water, rinsed, air-dried, and stored with silica gel to prevent fungal or bacterial contamination. All processed material was deposited in the Ichnology Collection of the Colecciones Biológicas de la Universidad CES (CBUCES-J), Medellín. Prey remains were photographed with a Canon EOS T7i camera and macro lens, using focus stacking in Helicon Focus 8.2.3 to produce fully focused composite images. Specimens were identified to the lowest possible taxonomic level by comparison with reference material housed at CBUCES, the Museo de Ciencias Naturales de La Salle (CNS), the Museum of Southwestern Biology (MSB), and the Colección Teriológica de la Universidad de Antioquia (CTUA). Diet was quantified using frequency of occurrence (FO) and relative biomass consumed (RBC). RBC was used to estimate the proportion of total prey biomass represented by each species. Published mean adult body masses were assigned to prey species, while unidentified sigmodontine rodents were estimated using dental allometry. Statistical analyses was used to evaluate sample completeness, and Kruskal–Wallis tests to assess variation across three time bins (2012–2016, 2018–2020, 2021–2022). Diet breadth was measured using Levins’ standardized niche breadth (Bsta). Diet similarity between study sites and previous research was assessed using Jaccard distance. Mean human disturbance values were extracted from raster data to derive effects of anthropogenic pressure.

Raw data of the study: Categorizing urban avoiders, utilizers, and dwellers for identifying bird conservation priorities in a northern Andean city
<p>This datasheet contains raw data on bird count records made from 2016 and 2019. Data were taken in urban and adjacent non-urban areas of Medellín, Colombia. It was part of a collaborative sampling effort during environmental assessments and personal research, summarizing systematic information on 139 sampling points (124 within the city and 15 in adjacent non-urban areas). All points were sampled under the same protocol in order to facilited data for research; in all cases, sampling was in charge of ornithologist with at least 4 years of previous experience in bird surveys. This protocol consisted in sampling during 10 minutes, four times per point (i.e., repetitions), using a fixed radius of 25 m. </p> <p>Information on bird surveys (Count_Data within the corresponding datasheet tab) contains the ID of each site; whether corresponded to a urban or non-urban site; in what category of urban development the site was located, based on 1000, 500 and 200 m buffers (from the observer during bird counts: moderate, low or high); the taxonomic information of each species (order, family, scientific name); the number of recorded individuals; the repetition or number of the visit (1, 2, 3, or 4); the name of the project; the name of the observer, and the date of sampling. </p> <p>Information on categorization of bird species (Categorization within the corresponding datasheet tab) represents additional information on altitudinal ranges, trophic guilds, distribution, and others. In addition, information on frequency for each bird species is given, according to the location of each sampling site and the way it was grouped. This information was the base for categorizing bird species as urban avoider, utilizer, or dweller, under the calculations and decision rules that are also given within the corresponding cells of the datasheet.</p> <p>Any further information or questions about this data could be ask directly, writing to the e-mails: jgarizabal@unal.edu.co or njmacer@unal.edu.co.</p> <p> </p>
