Monitoring tracer stones through the potholes of Fall Creek Gorge near Williamsport, Indiana
… embedded with Passive Integrated Transponder (PIT) tags using our new highly successful and efficient method for drilling holes into small (~ 10 mm) clasts. Repeated surveys of bed topography record deposition and erosion of sediment within potholes. Tracer clasts introduced upstream of the …

Seasonal habitat and movement ecology of adult brook trout in a northern Michigan headwater stream
… identified passive integrated transponder (PIT) tags. Mobile PIT antenna surveys were conducted at fine scales of four 35m focal reaches during four survey seasons, and at coarse scales of 31 100 m reaches during two survey seasons. All surveys were conducted during fall and spring …

Distribution, Movement, and Ecology of Etheostoma spilotum (Gilbert), the Kentucky Arrow Darter, in Gilberts Big Creek and Elisha Creek, Red Bird River Basin, Clay and Leslie Counties, Kentucky
… Utilizing passive integrated transponder (PIT) tags for continuous tracking, movements of 121 KADs ranged from 28-4,078m in both up and downstream directions. Population estimates ranged from 80-1498 individuals but varied depending on stream and season, with the spring season yielding the …

Salmonids in an Urban Stream: Movement, Habitat, and Potential Barriers
… This study used Passive Integrated Transponders (PIT-tags) to monitor the movement and habitat use of two salmonid species (<em>Salvelinus fontinalis</em> and <em>Oncorhynchus mykiss</em>) in an urban section of Wilson Creek, located in Ellensburg, Washington. Salmonids ranged in length from …

Investigating the Role of Long Distance Dispersal in the Response of Stream Fishes to Urbanization
… Species of interest were marked with 12mm HPT PIT tags and included a specialist, <em>Campostoma oligolepis </em>(n=189 urban site, 200 rural site) and a generalist, <em>Lepomis auritus</em> (n=136 urban site, 182 rural site). Three resampling instances for each site were conducted between …

Selection of benthic habitat by yellow-phase American eels (Anguilla rostrata)
… used one time only. All eels were injected with PIT tags prior to the study, which allowed for determination of lengths and otolith-based ages of each individual following each trial. Leaf pack was selected with a significantly higher probability than other substrates (63 of 130 individuals). …

Occurrence and genetic diversity of lemon sharks (Negaprion brevirostris) at a nursery ground at the Chandeleur Islands, Louisiana.
… and juveniles) were collected. Each shark was PIT tagged and a tissue sample was taken for genetic analyses. Sizes ranged from 56 – 177 cm total length. Sharks showed a preference for sandy substrate and smaller individuals showed significant preference for shallow waters. Collection data for …

Hydraulic and biological aspects of fish passes for dams
… between the two. Passive Integrated Transponder (PIT) tags together with antennae installed at a weir and an orifice were used to individually monitor the movement of wild spawning salmon passing through the fish pass. The results of the field test are as yet, inconclusive.

Comparative Biology of Sympatric Red Diamond and Southern Pacific Rattlesnakes in Southern California
… involving passive integrated transponders (PIT) tags, I studied Red Diamond (Crotalus ruber) and Southern Pacific (C. oreganus helleri) Rattlesnakes in Chino Hills State Park, California, from March 2003 through March 2010. The first of three studies compared the two species in terms of home …

Small water, big potential: farm ponds and their potential for native fish conservation
… as potential habitat for native species despite their ubiquity across many human altered landscapes. Farm ponds intermittently connect to streams during floods allowing species exchanges to and from these novel habitats. In 2014, a farm pond on Tallgrass Prairie National Preserve (TAPR) was …

Bayesian population dynamics modeling to guide population restoration and recovery of endangered mussels in the Clinch River, Tennessee and Virginia
… and Swan Island. Passive integrated transponder (PIT) tags were applied in my fieldwork to monitor the translocation efficiency of E. capsaeformis and Actinonaias pectorosa at Cleveland Islands (CRM 270.8). Hierarchical Bayesian models were developed to address the individual variability and …

Resource use and life history patterns of juvenile Coho and Chinook salmon in an Alaskan estuary
… Salmon. I used passive integrated transponder (PIT) tags and in-channel antennas to assess fish movement in two marsh channels. In the marsh channel that remained fully connected to the main channel at low tide, fish movement was mostly independent of the tidal stage or channel depth. In the …

Using instream stationary antennas to monitor the movements of warm water fishes in a reach of stream bisected by a culvert
… I used 12mm passive integrated transponder tags and four instream stationary antennas to monitor the movements 429 fishes. The antennas redetected 262 of the 429 individuals (61.1%), and 48% of fishes were redetected more than 10 times. The proportion of tagged individuals detected by …

Survival, Abundance, and Relative Predation of Wild Rainbow Trout in the Deerfield Reservoir System, South Dakota
… using 12 mm passive integrated transponder (PIT) tags which showed that within and among stream movement was minimal throughout our study. We tagged 380 Rainbow Trout and in subsequent sampling events recaptured 81 unique fish using backpack electrofishing. Of these 81 fish only 3 were …

Contribution of Natural Recruitment to the Rainbow Trout Oncorhynchus mykiss Sport Fishery in Deerfield Reservoir
… used passive integrated transponder technology (PIT) to track movements of tagged individuals of each strain between Deerfield Reservoir and its primary tributary system, Castle Creek. Two thousand and ninety-four rainbow trout were implanted with PIT tags in McNenny State Fish Hatchery (known …

The influence of spatiotemporal variation in ambient temperature on the ecology and physiology of birds
… passive integrated transponder (PIT) tags to measure three traits [UCT, heat-strain coefficient (HScoeff – the slope of the relationship between Tb and Ta above the UCT) and critical thermal maximum (CTmax – the Ta at which birds become hyperthermic and lose the ability to …
