Use of pop-up satellite archival tag technology to study postrelease survival of and habitat use by estuarine and coastal fishes: an application to striped bass (Morone saxatilis)

Pop-up satellite archival tags (PSATs) have been used to study movements, habitat use, and postrelease survival of large pelagic vertebrates, but the size of these tags has historically precluded their use on smaller coastal species. To evaluate a new generation of smaller PSATs for the study of postrelease survival and habitat use of coastal species, we attached Microwave Telemetry, Inc., X-tags to ten striped bass (Morone saxatilis) 94–112 cm total length (TL) caught on J hooks and circle hooks during the winter recreational fishery in Virginia. Tags collected temperature and depth information every five minutes and detached from the fish after 30 days. Nine of the ten tags released on schedule and eight transmitted 30% to 96% (mean 78.6%) of the archived data. Three tags were physically recovered during or after the transmission period, allowing retrieval of all archived data. All eight striped bass whose tags transmitted data survived for 30 days after release, including two fish that were hooked deeply with J hooks. The eight fish spent more than 90% of their time at depths less than 10 m and in temperatures of 6–9°C, demonstrated no significant diel differences in depth or temperature utilization (P>0.05), and exhibited weak periodicities in vertical movements consistent with daily and tidal cycles

The intraurethral device can include a urethral plug made from a biocompatible, flexible material. The intraurethral device can also include a first insertion element in operative communication with a second insertion element to facilitate self-insertion of the urethral plug into the urethra. Furthermore, in some instances, various mechanisms can be provided to keep the intraurethral device substantially sterile and/or clean prior to and/or during the insertion process

Tagging methods and associated data analysis

Tagging methods have a long history of use as tools to study animal populations. Although the first attempts to mark an animal occurred sometime between 218 and 201 B.C. (a Roman officer tied a note describing plans for military action to the leg of a swallow and when the bird was released it returned to its nest, which was in close proxiD?ity to the military outpost in need of the information), it is uncertain when fish : ere first marked (McFarlane, Wydoski and Prince, 1990). An early report published 1? The_ Comp/eat Angler in 1653 by Isaak Walton described how private individuals tied ribbons to the tails of juvenile Atlantic salmon (Salmo salar) and ultimately determined that Atlantic salmon returned from the sea to their natal river (Walton and (otton, ~ 898; McFarlane, Wydoski and Prince, 1990). Since the late 1800s, numerous fish tagging experiments have been conducted with an initial emphasis on salmonids followed soon after by successful attempts at tagging flatfish and cod. Pelagic species, namely Pacific herring (Clupea harengus pallasi) and bluefin tuna (Thrmnus thynnus) Were successfully tagged in the early 1900s, while elasmobranch tagging studies did not commence until the 1930s. Since 1945, large-scale tagging programmes have been initiated all over the world in an effort to study the biology and ecology of fish populations. Modern tagging studies can be separated into two general categories. Tag-recovery studies are those in which individuals of the target population(s) are tagged, released, and subsequently killed upon recapture, as in a commercial fishery; while capture-recapture studies are designed to systematically tag, release and recapture individuals on multiple sampling occasionshttps://scholarworks.wm.edu/vimsbooks/1025/thumbnail.jp

Intra-urethral device for incontinence and method for making and using the same

An intra-urethral device that can be used to inhibit leakage of urine due to incontinence is provided. The intra-urethral device can include a urethral plug made from a biocompatible, flexible material, and can be formed into an oblong shape so as to better correspond to the contours of the female urinary tract. In some instances, the intra-urethral device can also include an insertion element that can facilitate self-insertion and the ability of a fluid seal to form between the urethral plug and the walls of the urethra. Furthermore, in some instances, various mechanisms can be provided to keep the intra-urethral device substantially sterile throughout the insertion process

The trophic dynamics of summer flounder (Paralichthys dentatus) in Chesapeake Bay

Data on the trophic dynamics of fishes are needed for management of ecosystems such as Chesapeake Bay. Summer flounder (Paralichthys dentatus) are an abundant seasonal resident of the bay and have the potential to impact foodweb dynamics. Analyses of diet data for late juvenile and adult summer flounder collected from 2002−2006 in Chesapeake Bay were conducted to characterize the role of this flatfish in this estuary and to contribute to our understanding of summer flounder trophic dynamics throughout its range. Despite the diversity of prey, nearly half of the diet comprised mysid shrimp (Neomysis spp.) and bay anchovy (Anchoa mitchilli). Ontogenetic differences in diet and an increase in diet diversity with increasing fish size were documented. Temporal (inter- and intra-annual) changes were also detected, as well as trends in diet reflecting peaks in abundance and diversity of prey. The preponderance of fishes in the diet of summer flounder indicates that this species is an important piscivorous predator in Chesapeake Bay

The Impact of Program Context on Motivational System Activation and Subsequent Effects on Processing a Fear Appeal

This manuscript reports three experiments investigating the impact of television programming context on the processing of a fear-appeal message. This is done using a dual-motivation system theory conceptualizing emotion as arising from activation of the appetitive and/or aversive motivational systems. Results show that, as predicted, sad programming activates viewers\u27 aversive motivational systems, whereas comedic programming activates their appetitive motivational systems. Furthermore, by activating these systems through programming context, we were able to predict both retrospective self-report and real-time physiological reactions to a persuasive message employing a fear-appeal strategy. Theoretical and practical implications are discussed, as are suggestions for future experiments using the dual-motivation approach

Observations of the ultraviolet-bright star Y453 in the globular cluster M4 (NGC 6121)

We present a spectral analysis of the UV-bright star Y453 in M4. Model fits to the star´s optical spectrum yield Teff ∼ 56,000 K. Fits to the star´s FUV spectrum, obtained with the Cosmic Origins Spectrograph on board the Hubble Space Telescope, reveal it to be considerably hotter, with Teff ∼ 72,000 K. We adopt Teff = 72,000 ± 2000 K and log g = 5.7 ± 0.2 as our best-fit parameters. Scaling the model spectrum to match the star´s optical and near-infrared magnitudes, we derive a mass M∗ = 0.53±0.24 M⊙ and luminosity = log L/L⊙ 2.84±0.05, consistent with the values expected of an evolved star in a globular cluster. Comparing the star with post-horizontal-branch evolutionary tracks, we conclude that it most likely evolved from the blue horizontal branch, departing the asymptotic giant branch before third dredge-up. It should thus exhibit the abundance pattern (O-poor and Na-rich) characteristic of the second-generation (SG) stars in M4. We derive the star´s photospheric abundances of He, C, N, O, Si, S, Ti, Cr, Fe, and Ni. CNO abundances are roughly 0.25 dex greater than those of the cluster´s SG stars, while the Si and S abundances match the cluster values. Abundances of the iron-peak elements (except for iron itself) are enhanced by 1-3 dex. Rather than revealing the star´s origin and evolution, this pattern reflects the combined effects of diffusive and mechanical processes in the stellar atmosphere.Fil: Dixon, William V..

Intramedullary rod for fracture fixation of femoral shaft independent of ipsilateral femoral neck fracture fixation

A femoral intramedullary rod has a thin or reduced proximal segment so as to provide room for the use of femoral hip screws. Use of the rod for femoral shaft fixation permits subsequent independent treatment of an ipsilateral femoral hip fracture as an isolated injury, regardless of whether initially detected. Different rod embodiments are formed by the omission of different proximal portions of the rod. It is in such portions that the femoral screws may be placed to set hip fractures. The rod is cannulated for installation over a guide wire. Internal rod threads, below the thin proximal segment in some embodiments, are used for initial installation of the rod with a driving member screwed into such threads. Without driving forces on the thin proximal segment, such segment can be made even thinner. Once the rod is seated, hip screws may be installed if there is a detected hip fracture. Subsequent to healing, the femoral screws and interlocking screws (if any) may be removed. A hollow reamer sized for clearance over the intramedullary rod may be placed down over the top of the rod to cut away any bony tissue ingrown into the proximal end. Thereafter, the rod is extracted with a suitable extraction device
