In the authors' previous study, vegetation information was utilized into a hydrodynamic model to predict the flooding coverage and damage to the wetlands in a major water system in southwest Louisiana, the Calcasieu Lake water system. In this study, the target area is extended, ranging from the city of Lake Charles as the north end to the Gulf of Mexico as the south end, including Lake Charles, Calcasieu Lake, Prien Lake, Gulf Intracoastal Waterway (GIWW) and the entire Calcasieu Ship Channel. Measured vegetation data is utilized in the vegetated areas and appropriate friction values are assigned to different types of non-vegetated areas. Salinity is important to aquatic life. It can impact agricultural production, water quality and streams, biodiversity and infrastructure. In this study, both hydrodynamic and salinity transport simulations are conducted. Measurement data from NOAA and USGS are used as boundary conditions. Simulation results were compared with NOAA and USGS data in several other locations. Lake Charles is one of the largest petrochemical industry centers in the country. Numerous plants use tremendous amount of fresh surface water in the area. Recent expansions of several companies increase the fresh water withdraws from the system significantly. One of the purposes of the study is to investigate the effects of increased water withdraw on the hydrodynamics and salinity in the system. The industrial water withdrawals could be fro m the Calcasieu River in the north of Lake Charles, which is the north boundary of the simulation domain. Cases of different reduced flow rates at Lake Charles were tested, and the effects on hydrodynamics and salinity concentrations and distributions were analyzed. The results can be used as a guideline for industrial and city development in the areas. Copyright © 2016 by ASME.

Klebsiella oxytoca is a gram-negative bacterium that can be found throughout the environment as well as on mucosal membranes of mammals including humans. This bacterium is responsible for a variety of infections in humans including nosocomial infections resulting in hospital outbreaks. Reptiles including snakes, tuataras, and turtles have been shown to harbor this bacterium, and previous studies have shown that pet reptiles are a potential source for dissemination of pathogenic bacteria. Green anoles (Anolis carolensis) are a common lizard found in the southeastern part of the United States. For this study, the prevalence of K. oxytoca in free-living green anoles from Louisiana was tested to determine whether anoles are a possible source of pathogenic bacteria. Of the 42 green anoles tested, 7 (17%) were positive for K. oxytoca, demonstrating that anoles are a potential source for human infection from this bacterium.

Hyper trumps super: A central atom, typically a metal, surrounded by halogen or oxygen atoms is called a superhalogen. Theoretical calculations and experiments reveal that a new class of highly electronegative species can be created when the central metal atom is surrounded by superhalogen moieties. These hyperhalogens can have electron affinities even larger than those of their superhalogen building blocks. © 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

In this paper, a data-driven test is proposed to compare two independent or dependent stationary time series, in terms of the second order dynamics. We show that the problem of time series comparison is equivalent to a goodness-of-fit test checking if a constant model is adequate. Using the same framework, the proposed test is easily extended to compare multiple time series and time series of different lengths. Different to previous methods, it is based on generalized score statistics in an estimating equation setting, with some weak and flexible conditions. An extensive simulation study illustrates the validity of the asymptotic result and finite sample properties, using the tapered periodogram. The proposed test is found to perform well for many different situations, including time series with heavy-tailed or skewed innovations. An application to damage detection using vibration data is discussed. © 2011 Elsevier B.V. All rights reserved.

A new species of tardigrade, Minibiotus acadianus, is described from a moss sample collected in June 2009 from a rainforest palm tree on the island of Dominica, West Indies. The new species has a buccal tube with a single anterior curvature, two macroplacoids, and a microplacoid. The cuticle is smooth with small, evenly-distributed circular or elliptical pores. Eggs have a reticulated shell surface and short inverted goblet egg process; a dentate margin on the distal dish of the processes bears 1012 short teeth. The new species is most similar to Minibiotus acadianus Meyer & Domingue, 2011; both have wider buccal tubes than other species in the genus. The new species is easily distinguished from M. acadianus in lacking cuticular gibbosities and in some characters of the egg.

Terrestrial tardigrades were collected from moss, lichen and leaf litter from Grand Cayman in the Cayman Islands, West Indies. Six species were found. Milnesium tardigradum Doyère, 1840, Minibiotus intermedius (Plate, 1889), Paramacro-biotus areolatus (Murray, 1907) and P. richtersi (Murray, 1911) have been reported previously from other islands in the Caribbean Sea. Two species on Grand Cayman were new to science. Doryphoribius tessellatus sp. n. belongs to the 'evelinae-group', with two macroplacoids and cuticular gibbosities. In having two pairs of posterior gibbosities and cuticular depressions forming a reticular design, it is most similar to Doryphoribius quadrituberculatus Kaczmarek & Michalczyk, 2004 from Costa Rica. It differs from D. quadrituberculatus in its gibbosity sequence (III:4:2:2), the number of teeth, size of macroplacoids and details of the reticular design on the dorsal cuticle. Macrobiotus caymanensis sp. n. belongs to the 'polyopus-group' of species. It differs from other species of the group in having a shorter buccal tube, a more posterior stylet support insertion point and fewer, larger egg processes.

Abstract This paper provides a comprehensive list of the freshwater and terrestrial tardigrade fauna reported from the Americas (North America, South America, Central America and the West Indies), their distribution in the Americas, and the substrates from which they have been reported. Data were obtained from 316 published references. Authors' identifications were accepted at face value unless subsequently amended. Taxa were assigned to sub-national units (states, provinces, etc.). Many areas, in particular large portions of Central America and the West Indies, have no reported tardigrade fauna. The presence of 54 genera and 380 species has been reported for the Americas; 245 species have been collected in the Nearctic ecozone and 251 in the Neotropical ecozone. Among the tardigrade species found in the Americas, 52 are currently considered cosmopolitan, while 153 species have known distributions restricted to the Americas. Based on recent taxonomic revision of the genus Milnesium, the vast majority of records of M. tardigradum in the Americas should now be reassigned to Milnesium tardigradum sensu lato, either because the provided description differs from M. tardigradum sensu stricto or because insufficient description is provided to make a determination; the remainder should be considered Milnesium cf. tardigradum. Most terrestrial tardigrade sampling in the Americas has focused on cryptogams (mosses, lichens and liverworts); 90% of the species have been collected in such substrates. The proportion of species collected in other habitats is lower: 14% in leaf litter, 20% in soil, and 24% in aquatic samples (in other terrestrial substrates the proportion never exceeds 5%). Most freshwater tardigrades have been collected from aquatic vegetation and sediment. For nine species in the Americas no substrates have been reported Copyright © 2013 Magnolia Press.

Koasati is an endangered language with 200 speakers. This project is a collaborative endeavor among The Coushatta Tribe of Louisiana, an anthropologist at McNeese University, and linguists at The College of William and Mary and UC Santa Barbara to conduct the first phonetic study of Koasati. The data will be gathered over two years and will consist of analyses of scripted surveys of fluent speakers and conversational data. In order to maintain existing community support, the project will also seek to expand an existing audio dictionary of 1,200 words and to assist and train tribal members in lexicography, ethno-botany, and language documentation.

The intellectual merit of the proposal lies in providing basic, quantified data regarding Koasati consonants and vowels, the pitch accent system in nouns, the grammatical system of tone in verbs, as well as phrasal and sentence-level prosody. These aspects of Koasati are not well described, and the researchers pilot studies suggest important differences between Koasati and both Creek and Chickasaw. These findings will contribute to knowledge of sound patterns in Koasati, Muskogean languages, North American languages, and language in general. The multimedia dictionary will provide a lasting record of the pronunciation of words.

The project will have a broader impact in training tribal members in language documentation, in training graduate and undergraduate students in instrumental phonetics, and in providing a model within linguistics of collaborative, interdisciplinary, community-based research.

WSC-Category 1 Collaborative: A surface water management framework to counterbalance groundwater withdrawals in wetter regions of the U.S.

The over-use of groundwater is becoming a critical problem in regions historically characterized by abundant rainfall and surface water, including much of the U.S. Northern Gulf and Southern Atlantic Coastal regions. This project proposes to develop a theoretical framework and a new modeling/decision support tool aimed at better managing surface water so that it can be used to close groundwater supply gaps. The proposed management framework focuses on understanding human-water-land use interactions, with an emphasis on agriculture. The research team will explore the potentially transformative concept of integrating the social and biophysical dimensions of water systems into a unified framework for improved management of surface water resources. This includes consideration of the balance between water demand for humans and ecosystems.

The project team will develop an innovative geospatial decision support/modeling tool that can identify and evaluate opportunities to capture and use surface water to replace groundwater in these wetter regions of the US. The theoretical framework and associated geospatial decision support tool will be unique for wetter regions of the U.S. where groundwater and surface water have traditionally been managed separately and surface water management has focused largely on flood control. The tool will directly benefit farmers, land managers, regulatory agencies, and state and local government officials. The research will be integrated with education through a trans-disciplinary senior/MS-level course at UL Lafayette. Public outreach, focusing on water conservation efforts, will be part of this course. We will additionally leverage and expand existing NSF and NOAA watershed-based education/outreach projects that target graduate students and high school teachers, respectively. This project also serves as a catalyst for developing a new collaborative team of researchers interested in water sustainability.
