Bird detections from multi-species point surveys at lowland forest restoration sites, Indiana, United States, April – June 2016, with resampling code

These data pertain to bird point surveys collected from 30 April 2016 to 12 May 2016 and 23 May 2016 to 25 June 2016 at four bottomland hardwood restoration sites in northeastern Indiana. The data are a single monitoring occasion with the purpose of documenting bird communities across these sites. During the time of collection, sites contained areas of hardwood planting ranging in age from 2 to 22

Crayfish densities in relation to concentrations of metals in sediment and water in Madison County, Missouri, 2004-2015

Data was collected during a series of studies that assessed the effects of metals on crayfish in mining districts in Missouri. Adult crayfish were collected in riffles to determine whether crayfish densities were lower at sites downstream of mining areas compared to sites upstream of mining areas. Metal concentrations in surface or pore water and less than 2-mm sediment were measured and incorpora

Chronic toxicity of metals in two water hardness to three sizes of the crayfish Faxonius quadruncus Missouri, USA 2017-2018

Laboratory studies were conducted to examine the effect of water hardness and age of crayfish on the toxicity of environment-based metals mixture. Additionally, the effects of chronic exposure to a metals mixture to egg development in adult F. quadruncus were assessed. Mortality and growth of F. quadruncus were assessed. These data consist of attributes of water quality from toxicity tests and att

Effects of metals from historical mining on crayfish in Madison County Missouri USA, 2015

Deposits of lead (Pb) and other metals in southeastern Missouri, USA have been exploited since the 1700s. Metal contamination of fish and other aquatic biota, alteration of fish and invertebrate communities, and public health advisories against human consumption of Pb-contaminated fish have resulted. The Little Saint Francis River (LFSR) and its tributaries, which drain the mining-affected areas o

Complete female and male mitogenomes of the mucket mussel (Ortmanniana ligamentina)

Data include fasta files of full mitochondrial sequence data for the male and female mitotypes of the mucket (Ortamannia ligamentina). These have been deposited in the NCBI database under BioSample Accession number SAMN39271813, SRA Accession number SRR27608898, and GenBank Accession numbers : PP103562 and PP103563.

Mississippi River fishes collected by a suite of entanglement and entrapment gears; 2020-2023

Black Carp (Mylopharyngodon piceus) were imported to the United States for use as a biological control in aquaculture and have since escaped with reproducing populations in the wild. Habitat use and capture of this species has not been well documented in the wild, thus questions about catchability by gears and habitats are present. This dataset represents sampling effort to capture Black Carp with

Evaluation of fish behaviors in response to driven and undriven entanglement nets with emphasis on invasive Silver Carp, Central Missouri, 2015-2016

We used Adaptive Resolution Imaging Sonar (ARIS), which is based on Dual-Frequency Identification Sonar (DIDSON) technology to observe net encounter behaviors of bigheaded carps. Gill nets with four different mesh types (8.9 cm bar mesh) and trammel nets with five different mesh sizes (range 5.1-8.9 cm bar mesh) were evaluated. Net sets were undisturbed, or fish were driven with the noise of the o

Black Carp in North America: a description of range, habitats, date, and methods of reported captures May 2018-October 2022

Black Carp collections (n=534) by commercial fishers, biologists, and recreational anglers from the Mississippi River basin recorded from 2018 to 2022 are reported here. Geographic coordinates, total length (TL), weight, girth, date of capture, sex, and gear were recorded. Total length was measured from the tip of the snout to the longest caudal fin ray with the caudal fin lobes pinched. Girth was

Water chemistry data observed in experimental laboratory mesocosms exposed to different nitrapyrin and nitrogen amendments in the presence or absence of a nitrifier enriched microbial (NEM) community

These data describe the results of a controlled laboratory mesocosm experiment evaluating the effect of nitrapyrin, a nitrification inhibitor, on nitrification in a nitrifier enriched microbial (NEM) community. Parameters described include the water chemistry and nitrapyrin measurement results of experimental mesocosms. Microbial community data is described in a separate data release.

Growth and survival of a Unionid Mussel (Fatmucket, Lampsilis siliquoidea) and a Common Test Benthic Organism (Amphipod, Hyalella azteca) during Chronic Exposures to Mixtures in Sediment Contaminated by Unregulated Industrial Discharges.

This data set contains toxicity data from 28- and 84-day sediment bioassays to assess the effects of contaminated Kanawha River, West Virginia sediment on juvenile mussels (fatmucket, Lampsilis siliquoidea) and one commonly tested benthic invertebrate (amphipod, Hyalella azteca) following ASTM standard methods for conducting 4-week sediment toxicity tests with the mussel and amphipod. In addition,

Dike Fields and Macrohabitats of the Lower Missouri River

This project summarizes broad, two-dimensional spatial availability of fish habitat across the Lower Missouri River (from its confluence with the Big Sioux River near Sioux City, Iowa downstream to its confluence with the Mississippi River near St. Louis, Missouri). One of the main objectives of the project was to delineate and categorize dike fields, which we define as areas directly downstream f

Salinity tolerance of grass carp and silver carp during egg and early larval stages

We tested salinity tolerance of grass carp and silver carp eggs and larvae during two phases of development – pre-gas bladder inflation and post gas bladder inflation to the development of the second gas bladder chamber, using 6 different salinity concentrations ranging from 0 to 36 ppt. Growth and developmental rates were also observed after exposure. After the initiation of horizontal swimming,
