Data regarding the evaluation of the toxicity of zinc in 1-, 3-, 8-, 24-, and 48-hour exposures with a cladoceran (Ceriodaphnia dubia), and in 1-, 3-, 8-, 24-, and 96-hour exposures with rainbow trout (Oncorhynchus mykiss) on survival and mobility of test organisms.
This dataset is from the fourth of four experiments which test the toxicity of several metals with aquatic insect communities that were colonized in the field and then transferred and tested in experimental streams. Here we report original data from testing the toxicity of cobalt (Co), copper (Cu), and nickel (Ni), singly and in mixtures, to natural benthic communities including aquatic insect and algal communities. The methods are the same as those used in Experiment 3, except for the metals combinations. Trays of cleaned gravel were placed in a stream (the Cache La Poudre River, Colorado) and allowed to colonize for about 40 days before being translocated to Aquatic Experimental Stream Laboratory (AXL) which was...

This dataset is from the second of four experiments which test the toxicity of several metals with aquatic insect communities that were colonized in the field and then transferred and tested in experimental streams. Here we report original data from testing the toxicity of cadmium (Cd), zinc (Zn), and copper (Cu) singly and in mixtures, to natural aquatic insect communities. Thus, the exposures reproduced those in experiment 1, with the addition of a third metal, Cu Trays of cleaned gravel were placed in a stream (the Cache La Poudre River, Colorado) and allowed to colonize for about 40 days before being translocated to Aquatic Experimental Stream Laboratory (AXL) which was located at the USGS Fort Collins Science...

The purpose of this sampling was to collect matched aquatic insect and water samples to support metals mixture toxicity modeling. This is part of a larger study that included exposing naturally colonized insect communities to metals mixtures in long-term laboratory toxicity tests, field surveys, and modeling (Schmidt and others, 2019). The Panther Creek sampling was conducted to give a field comparison to laboratory exposures of aquatic insect communities to cobalt (Co) plus copper (Cu) mixtures, the results of which were presented as part 4 of Schmidt and others (2019). The water samples from the Panther Creek area were collected to interpret metals concentrations in the tissues of mayflies and caddisflies relative...
In a series of 4 experiments conducted over 4 years, natural lotic macroinvertebrate communities were colonized by placing baskets of large gravel in a riffle in the upper Cache La Poudre River, Colorado and leaving the baskets in place for 30-40 days. The communities were then exposed in experimental streams to different combinations of five metals (cadmium (Cd), cobalt (Co), copper (Cu), nickel (Ni), and zinc (Zn). The metals exposures and associated counts of larval insects and other invertebrates remaining in the experimental streams are detailed in Child Items 1-4 of this Data Release. In this dataset (child item #5), we report the associated adult insect counts by day that successfully metamorphosed during...

Little is known about how design and testing methodologies affect the macroinvertebrate communities that are held captive in mesocosms. To address this gap, we conducted a 32-day test to determine how seeded invertebrate communities changed once removed from the natural stream and introduced to the laboratory. We evaluated larvae survival and adult emergence in controls from 4 subsequent experiments, as well as corresponding within-river community changes. The experimental streams maintained about 80% of the invertebrates that originally colonized the introduced substrates. Many macroinvertebrate populations experienced changes in numbers through time suggesting that these taxa are unlikely to maintain static populations...

This dataset is from the first of four experiments which test the toxicity of several metals with aquatic insect communities that were colonized in the field and then transferred and tested in experimental streams. Here we report original data from an experiment testing the toxicity of cadmium (Cd) and zinc (Zn), singly and in mixtures, to natural aquatic insect communities. Trays of cleaned gravel were placed in a stream (the Cache La Poudre River, Colorado) and allowed to colonize for about 40 days before being translocated to Aquatic Experimental Stream Laboratory (AXL) which was located at the USGS Fort Collins Science Center. There the insects were exposed for 30 days to metal mixtures in ratios and concentrations...
This dataset is from the third of four experiments which test the toxicity of several metals with aquatic insect communities that were colonized in the field and then transferred and tested in experimental streams. Here we report original data from testing the toxicity of copper (Cu), nickel (Ni), and zinc (Zn), singly and in mixtures, to natural aquatic insect communities. Methods are the same as those in Experiment 2, with the addition of in situ, in-vivo fluorescence measurements of benthic algae. Cu Trays of cleaned gravel were placed in a stream (the Cache La Poudre River, Colorado) and allowed to colonize for about 40 days before being translocated to Aquatic Experimental Stream Laboratory (AXL) which was...
