The effects of temperature, latitudinal origin, and dam escapement on management of muskellunge
No full textMuskellunge Esox masquinongy are commonly stocked to either maintain or supplement populations across the Midwestern United States. The objectives of most fish stockings are to maximize survival and growth. Many potential factors influencing stocking success of muskellunge have been identified including temperature, predation, handling stress, competition, prey availability, habitat, dam escapement, and genetic or latitudinal origin. Much work remains to be done exploring the significance and interaction between several of these variables. My thesis focuses on temperature, source latitude of populations, and dam escapement as factors influencing growth and survival of muskellunge. Three different genetic groupings of muskellunge have been identified as the Upper Mississippi, Ohio, and St. Lawrence River drainage stocks. Different populations occurring across a range of latitudes and climates exist within each of these stocks. A recent and increasingly popular strategy in muskellunge management is to identify and utilize populations with perceived growth advantages for stocking. However, there is little understanding of how stocks, and populations within stocks, may vary in their physiological tolerance to thermal stress and the implications when relocating fish. In the first study I examined thermal tolerance among populations representing several stocks of muskellunge from varying latitudes using lethal chronic thermal maxima and sub-lethal physiological stress response experiments. Contrary to expectations, I found few indications that muskellunge populations included in this study differed in their capacity to withstand heat challenges. Other sources of mortality should be examined to explain survival differences among these populations that may be observed in the field. I also expected physiological differences at the population level to influence growth rates of muskellunge. In the second study I attempted to understand thermal adaptation of growth among latitudinally separated muskellunge populations using bioenergetics modeling to explore whether approaches refined to the population level would improve accuracy and usefulness of future modeling efforts. Bioenergetics modeling simulations indicated that growth rates of muskellunge populations may be adapted to native thermal environments. In addition to many other known factors, survival of muskellunge stocked into reservoirs may also be influenced by dam escapement. Escapement from reservoirs has been identified as one of the unknown factors in muskellunge management, thought to have the potential to greatly reduce abundance and structure populations. Laboratory studies of a simulated spillway and field evaluations utilizing a PIT tag interrogating antennae found dam escapement of muskellunge to be more prevalent during the day. Field evaluations of escapement also found 20% of a reservoir population to escape in one year, with adults escaping more than juveniles. Results of my thesis demonstrate that interactions between latitudinal origin and temperature may have influences on growth more so than survival of stocked muskellunge, and that dam escapement is an important factor influencing management of reservoir populations.Item withdrawn by Mark Zulauf ([email protected]) on 2012-04-26T19:41:57Z

A Transfer Report on the Development of a Framework to Evaluate Search Interfaces for their Support of Different User Types and Search Tactics
No full textAs the understanding of search systems, user needs and seeking strategies is developing, the design of search user interfaces is evolving to support more complicated and exploratory forms of search. With the design of new search features that enable these richer modes of exploration, comes the need to better understand the support they provide. In this report a new evaluation framework is presented that analyses search features for how they a) contribute to an overall interface, b) allow users to carry out different search tactics, and c) support different types of users and their needs. The novel contributions of the framework improve on some of the limitations of typical user studies, and allow search systems to be systematically analysed in much more detail and in much less time. The presented evaluation framework is then validated in three ways. First the validity of the models used as the building blocks of the framework are investigated through related work. Second the method of integrating these building-block models is validated and strengthened by consensus of expert opinion. Third, the overall approach is validated by comparing its analyses to the results of previously carried out user studies. The validation process has shown both the value of the framework and identified areas of future work that should be addressed for the framework to be completed. This report concludes with the set of contributions that the framework makes, and why the remaining work will be challenging, but critical to the final design
An accurate and efficient algorithm for real-time localisation of photoswitchable fluorophores
No full textWolter S. An accurate and efficient algorithm for real-time localisation of photoswitchable fluorophores. Bielefeld (Germany): Bielefeld University; 2009.This work scrutinises the deconfinement problem of photoswitching microscopy. The task of deconfinement is locating the sources of fluorophoric emission with subpixel accuracy in large sequences of images, which are acquired by temporally confining photoswitching microscopy.
The preceding work on this task is summarised and formulated with a standardised terminology. Then, the novel approach of motivational fitting is introduced, which greatly reduces the number of nonlinear fit attempts that are needed. A complete algorithmic concept and an implementation are given for this approach, along with a visualisation based on weighted histogram equalisation.
The resulting implementation in C++ code is verified and used for extensive testing of the chosen algorithms and of the important alternatives. Major parameters are determined experimentally on both real and simulated data. Additionally, it is proven that the deconfinement problem can be solved well within the real-time domain for a wide range of acquisition speeds and parameter choices. This includes the published parameters for the major temporally confining photoswitching microscopy methods.
This real-time capability alleviates the computational burden of temporally confining photoswitching microscopy and can considerably aid wide-spread use of these methods
The subzero microbiome: Microbial activity in frozen and thawing soils
No full textMost of the Earth's biosphere is characterized by low temperatures (<5 °C) and cold-adapted microorganisms are widespread. These psychrophiles have evolved a complex range of adaptations of all cellular constituents to counteract the potentially deleterious effects of low kinetic energy environments and the freezing of water. Microbial life continues into the subzero temperature range, and this activity contributes to carbon and nitrogen flux in and out of ecosystems, ultimately affecting global processes. Microbial responses to climate warming and in particular, thawing of frozen soils are not yet well understood although the threat of microbial contribution to positive feedback of carbon flux is substantial. To date, several studies have examined microbial community dynamics in frozen soils and permafrost due to changing environmental conditions, and some have undertaken the complicated task of characterizing microbial functional groups and how their activity changes with changing conditions, either in situ or by isolating and characterizing macromolecules. With increasing temperature and wetter conditions microbial activity of key microbes and subsequent efflux of greenhouse gases also increase. In this review, we aim to provide an overview of microbial activity in seasonally frozen soils and permafrost. With a more detailed understanding of the microbiological activities in these vulnerable soil ecosystems, we can begin to predict and model future expectations for carbon release and climate change.Peer reviewe
