Unique and shared effects of local and catchment predictors over distribution of hyporheic organisms: does the valley rule the stream?
<p>This dataset describe the distribution of two hyporheic crustacean taxa (Bogidiellidae, Amphipoda and Anthuridae, Isopoda) in streams of New Caledonia. We sampled the two taxa at 228 sites. At each site, we quantified nine local predictors related to habitat area and stability, sediment metabolism and water origin, and eight catchment predictors related to geology, area, primary productivity, land use and specific discharge.</p>
Measurements of heavy metals in the moss Orthotrichum lyellii collected using community science in the Duwamish Valley, Seattle, Washington, U.S.A.
<p>Heavy metals concentrations often vary at small spatial scales not captured by air monitoring networks, with implications for environmental justice in industrial-adjacent communities. Pollutants measured in moss tissues are commonly used as a screening tool to guide use of more expensive resources, like air monitors. We piloted a community science approach, engaging over 55 people from nine institutions, to map heavy metals using moss in two industrial-adjacent neighborhoods. Local youth led sampling of the moss <em>Orthotrichum lyellii</em> from trees across a 250×250-m sampling grid (n = 79). We compared their data with expert-collected samples (n = 19) using Principal Components Analysis and Procrustes Analysis. We mapped 21 chemical elements measured in moss, focusing on 6 toxic 'priority' metals: arsenic, cadmium, chromium, cobalt, lead, and nickel. We compared local data, using t-tests and boxplots, with two 'reference datasets' of <em>O. lyellii</em> collected in Portland, Oregon, and in Seattle City Parks. We also use Principal Components Analysis to describe major gradients in metals in the study area. Our data submission includes two R scripts and four datasets of heavy metals in moss, including the two reference datasets, which will enable replication of our analyses as well as novel analyses.</p>

Data from: Loss-of-heterozygosity facilitates a fitness valley crossing in experimentally evolved multicellular yeast
<p>These data sets are generated to investigate a simple evolutionary landscape that arises from underdominance at a single locus where the fitness valley consists of only one less-fit genotype. We make use of an experimental system previous evolved in the laboratory, the S<em>accharomyces cerevisiae</em> snowflake system. This system was experimentally selected resulting in a significant evolutionary shift, the transition from uni-to-multicellularity in asexual diploid populations. We carried out the phenotypic and fitness characterization of the strains. Additionally, we observed a rapid loss of heterozygosity (LOH) events in the heterozygote strains. Experimental evolution starting with the heterozygote strains suggests that LOH is common both under selection and without selection. LOH event drive adaptation that may enable rapid evolution in diploid yeast. </p>
Intrinsic vulnerabilty maps for the Telesina Valley (IT), Marchfeld (AT) and Zala County (HU)
<p>The dataset contains the maps of the soil intrinsic vulnerability for three case studies, the Telesina Valley in Italy, the Marchfeld region in Austria and the Zala County in Hungary, simulated using the TFM-ext model (Bancheri et al.,2021). The maps show the intrinsic vulnerability, categorized in 6 classes, from very low to extremely high, according to the estimated mean travel times. The model considered the spatially varying pedoclimatic conditions (i.e., georeferenced hydraulic properties and climate) to evaluate the mean travel times of a generic non-reactive solute till the bottom of the soil profiles. Then, the normalized values were computed and categorized. </p> <p> </p>

Supplementary data for: Outmigrating central valley Chinook Salmon
<p>Intraspecific diversity plays a critical role in the resilience of Chinook salmon populations. California's Central Valley historically hosted one of the most diverse population complexes of Chinook salmon in the world. However, anthropogenic factors have dramatically decreased this diversity, with severe consequences for population resilience. Here we use next generation sequencing and an archive of thousands of tissue samples collected across two decades during the juvenile outmigration to evaluate phenotypic diversity between and within populations of Central Valley Chinook salmon. To account for highly heterogeneous sample qualities in the archive dataset, we develop and test an approach for population and subpopulation assignments of Central Valley Chinook salmon that allows inclusion of relatively low-quality samples while controlling error rates. We find significantly distinct outmigration timing and body size distributions for each population and subpopulation. Within the archive dataset, spring run individuals that assigned to the Mill and Deer Creeks subpopulation exhibited an earlier and broader outmigration distribution as well as larger body sizes than individuals that assigned to the Butte Creek subpopulation. Within the fall run population, individuals that assigned to the late-fall run subpopulation also exhibited an earlier and broader outmigration distribution and larger body sizes than other fall run fish in our dataset. These results highlight the importance of distinct subpopulations for maintaining remaining diversity in Central Valley Chinook salmon, and demonstrates the power of genomics-based population assignments to aid the study and management of intraspecific diversity.</p>
