Aquatic insect populations in transplanted and natural populations of the purple pitcher plant, Sarracenia purpurea, on Prince Edward Island, Canada
No full textIn early July 1991, 234 pitcher plants (Sarracenia pulpurea) were transplanted from a Prince Edward Island bog being mined for peat into three bogs that varied with respect to previous pitcher plant abundance. One bog had a thriving natural pitcher plant population prior to transplant, while the other two had fewer than three pitcher plants. Between mid-June and late August 1993, abundances of the pitcher plant inquilines Wyeomyia smithii (Diptera: Culicidae), Metriocnemus knabi (Diptera: Chironomidae) and an unidentified sarcophagid fly (Diptera: Sarcophagidae) from transplant bogs were compared with remaining populations in die source bog and with other natural populations. Of the three inquilines, W. smithii was the most severely affected by transplant; it was extremely rare or absent in transplanted pitchers, although it was found in all other bogs investigated on Prince Edward Island. Metriocnemus knabi larvae were common in ail bogs investigated, except for those transplant bogs where pitcher plants were rare prior to transplant. Sarcophagid larvae were found in all of the bogs sampled, and were apparently unaffected by transplant. Desiccation during the transplant process, as well as the time of the transplant, may play a role in the success of recolonization of the pitcher plants after transplanting.PT: J; CR: ADDICOTT JF, 1974, ECOLOGY, V55, P475 BRADSHAW WE, 1984, AM MIDL NAT, V112, P294 CAMERON CJ, 1977, CAN J ZOOL, V55, P2018 ELLIOTT JM, 1977, FRESHWATER BIOL ASS, V25 FAIRCHILD WL, 1987, CAN ENTOMOL, V119, P647 FARKAS MJ, 1986, CAN ENTOMOL, V118, P1307 FARKAS MJ, 1986, CAN J ZOOL, V64, P285 FISH D, 1978, AM MIDL NAT, V99, P172 FORSYTH AB, 1975, CAN J ZOOL, V53, P174 GIVNISH TJ, 1989, PLANT ANIMAL INTERAC, P243 HEARD SB, 1994, ECOLOGY, V75, P1647 HEARD SB, 1994, ENVIRON ENTOMOL, V23, P1250 ISTOCK CA, 1975, EVOLUTION, V29, P296 ISTOCK CA, 1983, PHYTOTELMATA TERREST, P191 JUNIPER BE, 1989, CARNIVOROUS PLANTS MOGI M, 1980, TROPICAL MED, V22, P1 MOORE PD, 1974, PEATLANDS NASTASE AJ, 1991, AM MIDL NAT, V125, P356 NASTASE AJ, 1995, AM MIDL NAT, V133, P44 PATERSON CG, 1982, CAN J ZOOL, V60, P3075 SCHNELL DE, 1976, CARNIVOROUS PLANTS U WALLIS RC, 1967, MOSQ NEWS, V27, P9; NR: 22; TC: 5; J9: CAN J ZOOL; PG: 8; GA: VQ081Source type: Electronic(1

Beer, Brats, Cheese, and-- Baseball: The History and Impact of Baseball in Wisconsin
Get PDFFrom the 1800s baseball became a passion for the citizens of the United States. Wars, recessions and scandals could not bring down what is known as "America's Pastime." However baseball and other professional sports have been getting a bad name since historians and economist have started to look at the correlation between the team and the community. The notion of, "build us a new stadium at the cost of the tax payers or we are taking our team elsewhere" has been a common trend since 1950's. By looking at Appleton and Milwaukee this paper will look at the impacts baseball has on these communities both culturally and economically from 1966 to 2012
Stepwise Add-On and Endotype-informed Targeted Combination Therapy to Treat Obstructive Sleep Apnea: A Proof-of-Concept Study
No full textRationale: Oral appliance therapy (OAT) is an effective treatment for many people with obstructive sleep apnea (OSA). However, OSA pathogenesis is heterogeneous, and, in ∼50% of cases, OAT does not fully control OSA. Objectives: This study aimed to control OSA in individuals with an incomplete response to OAT alone by using additional targeted therapies informed by OSA endotype characterization. Methods: Twenty-three people with OSA (apnea–hypopnea index [AHI], 41 ± 19 events/h) not fully resolved (AHI, >10 events/h) with OAT alone were prospectively recruited. OSA endotypes were characterized pretherapy during a detailed physiology study night. Initially, an expiratory positive airway pressure (EPAP) valve and supine avoidance device therapy were added to target the impaired anatomical endotype. Those with residual OSA (AHI, >10 events/h) then received one or more nonanatomical interventions based on endotype characterization. This included O2 (4 L/min) to reduce high loop gain (unstable respiratory control) and 80/5 mg atomoxetine-oxybutynin to increase pharyngeal muscle activity. Finally, if required, OAT was combined with EPAP and continuous positive airway pressure (CPAP) therapy. Results: Twenty participants completed the study. OSA was successfully controlled (AHI, <10 events/h) with combination therapy in all but one participant (17 of 20 without CPAP). OAT plus EPAP and supine avoidance therapy treated OSA in 10 (50%) participants. OSA was controlled in five (25%) participants with the addition of O2 therapy, one with atomoxetine-oxybutynin, and one required O2 plus atomoxetine-oxybutynin. Two participants required CPAP for their OSA, and another was CPAP intolerant. Conclusions: These novel prospective findings highlight the potential of precision medicine to inform targeted combination therapy to treat OSA.Atqiya Aishah, Benjamin K. Y. Tong, Amal M.

defined many times (e.g., Menard, 1964; Wessel, 2001; Schmidt and
Schmincke, 2000; Pitcher et al., 2007; International Hydrographic
Organization, 2008; Wessel et al., 2010) but there is no “generally

Geographic Variation in Network Structure of a Nearctic Aquatic Food Web
Get PDFAim: The network structure of food webs plays an important role in the maintenance of diversity and ecosystem functioning in ecological communities. Previous research has found that ecosystem size, resource availability, assembly history and biotic interactions can potentially drive food web structure. However, the relative influence of climatic variables that drive broad-scale biogeographic patterns of species richness and composition has not been explored for food web structure. In this study, we assess the influence of broad-scale climatic variables in addition to known drivers of food web structure on replicate observations of a single aquatic food web, sampled from the leaves of the pitcher plant (Sarracenia purpurea), at different geographic sites across a broad latitudinal and climatic range. Location: Using standardized sampling methods, we conducted an extensive ‘snapshot’ survey of 780 replicated aquatic food webs collected from the leaves of the pitcher plant S. purpurea at 39 sites from northern Florida to Newfoundland and westward to eastern British Columbia. Methods: We examined correlations of 15 measures of food web structure at the pitcher and site scales with geographic variation in temperature and precipitation, concentrations of nutrients from atmospheric nitrogen deposition, resource availability, ecosystem size and the abundance of the pitcher plant mosquito (Wyeomyia smithii), a potential keystone species. Results: At the scale of a single pitcher plant leaf, linkage density, species richness, measures of chain length and the proportion of omnivores in a web all increased with pitcher volume. Linkage density and species richness were greater at high-latitude sites, which experience low mean temperatures and precipitation and high annual variation in both of these variables. At the site scale, variation in 8 of the 15 food web metrics decreased at higher latitudes, and variation in measures of chain length increased with the abundance of mosquitoes. Main conclusions: Ecosystem size and climatic variables related to latitude were most strongly correlated with network structure of the Sarracenia food web. However, in spite of large sample sizes, thorough standardized sampling and the large geographic extent of the survey, even the best-fitting models explained less than 40% of the variation in food web structure. In contrast to biogeographic patterns of species richness, food web structure was largely independent of broad-scale climatic variables. The large proportion of unexplained variance in our analyses suggests that stochastic assembly may be an important determinant of local food web structure.Organismic and Evolutionary BiologyAccepted Manuscrip

Using Stepwise Logistic Regression to Determine Substitutions in Baseball
No full textabstract: In baseball, a starting pitcher has historically been a more durable pitcher capable of lasting long into games without tiring. For the entire history of Major League Baseball, these pitchers have been expected to last 6 innings or more into a game before being replaced. However, with the advances in statistics and sabermetrics and their gradual acceptance by professional coaches, the role of the starting pitcher is beginning to change. Teams are experimenting with having starters being replaced quicker, challenging the traditional role of the starting pitcher. The goal of this study is to determine if there is an exact point at which a team would benefit from replacing a starting or relief pitcher with another pitcher using statistical analyses. We will use logistic stepwise regression to predict the likelihood of a team scoring a run if a substitution is made or not made given the current game situation
Fables Choisies
No full textThis book has the same cover as a softbound book by the same publisher, but where that has Série 76/3 and a design of GA on its back cover, this hardbound book has Série 80/3 and three colored scenes: The Father and His Sons, The Crow with Peacock Feathers, and The Mule Carrying a Relic. That book had 48 continuously paginated pages. This has one set of 16 pages set inside another, specifically between 8 and 9. This copy has no title-page. The images are signed J.G. but without a title-page there is no indication that J. Gouppy is the artist. There are three types of art in this book 8 x 11½ in size. There is a large colored cameo on the front cover. Signed Maury, it is a sentimental picture of a child as the milkmaid whose pitcher has broken. The eight colored pages by Gouppy are all here; they again combine different irregularly-shaped panels illustrating various fables. One (the first 8) combines The Worker and His Sons, The Ass Carrying Relics, and BF. Two of these pages are placed together at the centerfold of the book. The best of these full-page colored illustrations is perhaps the combination on the first 9 of WL and The Horse and the Donkey. These colored illustrations are simple but lively. Every fable has at least one simple appropriate one-colored design. Among the better designs are those picturing the coachman with the fly on his nose (16) and OR (1), Several others that I liked particularly in the other edition are not here. This particular Buchinist searched for me, but I was lucky enough to find this book myself.This is a hardbound book (hard cover)Language note: FrenchJean de la Fontain
