Tailwater time series and telemetry receiver range testing data for Kentucky Dam between 2021 and 2022 Tailwater time series and telemetry receiver range testing data for Kentucky Dam between 2021 and 2022
Invasive carp residency patterns in dam tailwaters are poorly understood. To better inform removal efforts in dam tailwaters, we examined multiple predictors of invasive carp residency in the Kentucky Dam tailwater between 2021 and 2022. This data release contains a time series dataset with daily counts and daily mean residence times of Silver Carp (Hypophthalmichthys molitrix) recorded...
Data for dam passage analysis of Silver Carp at three locks and dams on the Tennessee and Cumberland rivers from 2016–2019 Data for dam passage analysis of Silver Carp at three locks and dams on the Tennessee and Cumberland rivers from 2016–2019
Acoustic telemetry data (Innovasea, Inc.) were collected on invasive Silver Carp (Hypophthalmichthys molitrix) in the lower reaches of the Tennessee and Cumberland river systems to determine timing and environmental conditions associated with dam passages by Silver Carp during 2016–2019. Data also include water level. dam discharge, and lock use data for three dams within these river...
Data to assess silver and bighead carp pool to pool movements from 2012 through 2019 in the Illinois River, USA through Bayesian multistate transition models (ver. 2.0, June 2024) Data to assess silver and bighead carp pool to pool movements from 2012 through 2019 in the Illinois River, USA through Bayesian multistate transition models (ver. 2.0, June 2024)
The dataset and accompanying analysis scripts accompany the article "Bayesian multistate models allow incorporation of spatial dynamics to improve invasive species management". The data are summarized detections from acoustic telemetry receivers (69 KHz) from 353 silver carp (Hypophthalmichthys molitrix) and 170 bighead carp (H. nobilis) surgically implanted with transmitters in the...
Data release for an experimental translocation of invasive bigheaded carps and upstream passage success at a navigation lock Data release for an experimental translocation of invasive bigheaded carps and upstream passage success at a navigation lock
This dataset accompanies the article 'Upstream experience and experimental translocation of invasive bigheaded carps results in increased upstream passage success at a navigation lock in a large river'. The data come from the experimental capture and tagging of invasive bigheaded carp with acoustic transmitters and physically moving some groups farther downstream. These transmitters emit...
2017-2019 Telemetry data for invasive carp and paddlefish surrounding Lock and Dam 15 in the Upper Mississippi River Basin 2017-2019 Telemetry data for invasive carp and paddlefish surrounding Lock and Dam 15 in the Upper Mississippi River Basin
This dataset includes information derived from a Vemco telemetry array located at Lock and Dam 15 on the Mississippi River near Rock Island, IL and a longitudinal telemetry array that ranges from Pool 14 to Pool 19. Silver carp, bighead carp, and paddlefish were detected with this system. Lock Queue Reports, which detail the daily lock operation for river traffic, were obtained from the...
Above- and belowground biomass production, decomposition, and wetland elevation change in transitional coastal wetland communities exposed to elevated CO2 and sediment deposition: a mesocosm study from 2012 to 2014 Above- and belowground biomass production, decomposition, and wetland elevation change in transitional coastal wetland communities exposed to elevated CO2 and sediment deposition: a mesocosm study from 2012 to 2014
This data release includes belowground primary productivity, decomposition, and surface elevation change data from a two-year mesocosm experiment from 2012 to 2014. We conducted experimental greenhouse manipulations of atmospheric CO2 (double ambient CO2) and sediment deposition to simulate a land-falling hurricane under future climate conditions. Experimental greenhouse conditions...

Tailwater residency patterns of Silver Carp at Kentucky Lock and Dam Tailwater residency patterns of Silver Carp at Kentucky Lock and Dam
Objective The management of invasive Silver Carp Hypophthalmichthys molitrix in the Tennessee River basin focuses on removal, and there is interest in extending removal efforts to the tailwater environments of high-head locks and dams along the Tennessee River, such as Kentucky Dam. We used acoustic telemetry data from Silver Carp to understand important ecological associations...

Bayesian multistate models for measuring invasive carp movement and evaluating telemetry array performance Bayesian multistate models for measuring invasive carp movement and evaluating telemetry array performance
Understanding the movement patterns of an invasive species can be a powerful tool in designing effective management and control strategies. Here, we used a Bayesian multistate model to investigate the movement of two invasive carp species, silver carp (Hypophthalmichthys molitrix) and bighead carp (H. nobilis), using acoustic telemetry. The invaded portions of the Illinois and Des...

Upstream experience and experimental translocation of invasive bigheaded carps results in increased upstream passage success at a navigation lock in a large river Upstream experience and experimental translocation of invasive bigheaded carps results in increased upstream passage success at a navigation lock in a large river
Fish movements in regulated rivers can be challenging to study because anthropogenic modifications, such as locks and dams, can influence animal behavior. Upper Mississippi River Lock and Dam 19 (LD 19), for example, is an invasive carp movement bottleneck due to an impassable dam. Upstream fish passage at LD19 is restricted to the lock chamber, making it an optimal location to test...

Hydrological and lock operation conditions associated with paddlefish and bigheaded carp dam passage on a large and small scale in the Upper Mississippi River (Pools 14–18) Hydrological and lock operation conditions associated with paddlefish and bigheaded carp dam passage on a large and small scale in the Upper Mississippi River (Pools 14–18)
Movement and dispersal of migratory fish species is an important life-history characteristics that can be impeded by navigation dams. Although habitat fragmentation may be detrimental to native fish species, it might act as an effective and economical barrier for controlling the spread of invasive species in riverine systems. Various technologies have been proposed as potential fish...
