These tabular data were compiled to document how key plant trait values change during plant development, particularly seedling stages, and in relation to soil moisture. An objective of our study was to answer three main research questions: (1) Do seedling trait values differ across early to late stages of seedling development and do those trajectories vary among plant species and functional types (i.e., forbs vs. grasses)?; (2) Does water availability influence seedling ontogenetic trait variation? and, if so, does this variation affect plant species drought performance?; and (3) Do seedling trait values at early stages of development differ from complied trait database values for species? These data represent key...
This dataset contains the results of a laboratory chronic bioassay with 6-week-old juvenile mussels (Fatmucket, Lampsilis siliquoidea) in a 28-day zinc exposure (120 and 240 micrograms zinc per liter) with endpoints of survival and growth (biomass and length) following standard ASTM methods. Surviving mussels were transferred from the control and treatment groups into a culture pond and their survival and growth were monitored for 56 days. In this data release we report individual biological, chemical, and water quality measurements from the laboratory toxicity test exposure and pond grow-out period.
These data were compiled to examine rates of skipped migration in adult humpback chub that spawn in the Little Colorado River (LCR). These data include mark-recapture information from the lower 13.56 kilometers of the LCR and from the Colorado River, from river kilometer 105.5-145.7 downstream of Glen Canyon Dam. Data also include detections from a multiplexer array (MUX) that is located in the LCR and from submersible PIT tag antennas that are deployed in parts of the Colorado River. These data are capture histories that include both spring and fall sampling events that occurred between spring 2009 and spring 2019. Capture histories can include information about size (small adults being 200-249mm total length and...
Field observations in a Lake Ontario embayment suggested that there is a phototaxic response of larval cisco that changes with development. This switch was verified using cultured cisco in a laboratory environment. These data include counts of cisco larvae at three depth ranges within multiple 95 liter tanks. Each tank of larvae were exposed to one of three different light treatments with three replicate tanks per treatment. Light treatments were 24 hours per day of light exposure, 24 hours per day in darkness, and a 12-hour light then 12-hour dark exposure cycle. Observations of cisco positioning within the water column were recorded periodically. The information collected included the date and time of the observation,...

As such, numerous entities actively or incidentally involved in python research or management activities contributed specimens and/or data to this dataset, including but not limited to the U.S. Geological Survey, National Park Service, U.S. Fish...
This dataset contains information about 58 hatchling Burmese pythons collected in 2015 from an invasive population in southern Florida. These hatchlings were used in an experiment that assessed the effects of food availability, clutch, and sex on their growth in captivity. The hatchlings were collected as eggs from the nests of two wild pythons, assigned to High or Low feeding treatments, and their growth and meal consumption were monitored for 12 weeks. The dataset includes their hatch dates, feeding treatment groups, clutch designations, sex, weekly morphometric measurements, feeding activity, and feeding behavior.
This dataset contains the information necessary for bioenergetics modeling of rainbow trout growth in select tributaries to the Upper Skagit River Hydroelectric reservoirs.

The input data generated for modeling can be found in the folder 'FB4 Upper Skagit Tributaries - Data Release' and includes stream temperatures derived from direct observations, fish size-at-age from scale analysis, and fish diet and stream invertebrate drift data. Output data and log files from our modeling in the associated publication is also included in this folder. Please refer to the associated publication for additional details about...
Xenopus laevis tadpoles were held in 4 replicate vivaria for each of 4 treatments of neonicotinoid pesticides and one control treatment for at least one month (Control media, thiamethoxam high concentration of 100 ppm, thiamethoxam low concentrations of 20 ppm, clothianidin high concentrations of 100 ppm, and clothianidin low concentration of 20 ppm). Water was sampled for chemical testing on Day 33. Between Day 1 and 44, instantaneous measures of length were collected on a random selection of tadpoles from each vivarium. On Day 44, tadpole length (mm), weight, and developmental stage (Nieuwkoop-Faber staging) were measured for all tadpoles in all vivaria (three of the measured individuals from each replicate...

These data were compiled to fit Bayesian state-space growth in length models to estimate the environmental variables that influence flannelmouth sucker growth rates in the Grand Canyon. Objective(s) of our study were to quantify monthly intervals of growth of flannelmouth suckers in four river reaches, and test if novel high frequency gross primary productivity data would be a significant predictor of fish growth. These data represent capture histories for flannelmouth sucker (Catostomus latippinis) in the mainstem of the Colorado River within the Grand Canyon (river mile 0 to 226) from 2012-2018 and environmental variable data including water temperature, turbidity, and gross primary productivity. Fish data refer...
