Since the initial filling of Three Gorges Reservoir (TGR), serious phytoplankton blooms have occurred in its tributary bays. Cyanobacteria blooms have been observed in a number of tributary bays and threaten the drinking water security of residents in the TGR region. To identify the key factors controlling phytoplankton blooms in tributary bays and propose an effective management strategy, a one-year water quality study (November 2009 to October 2010) was conducted in Xiangxi Bay (XXB) of TGR. The results show that a rapid decrease in mixing depth is associated with the spring bloom, fading of the fall bloom occurs with the rapid increase in mixing depth, and an extremely shallow mixing depth is associated with cyanobacteria blooms that predominate during the summer. Development of thermal stratification in XXB is the major cause of seasonal variation in mixing depth and density current intrusion from TGR is the major cause of short-term variation in mixing depth. The seasonal thermal stratification of XXB is disrupted by sufficiently large water level fluctuations in TGR. The density current is lifted from mid-depths to the surface and chlorophyll a concentrations rapidly decrease in response. Based on these findings, a conceptual model is proposed for a management strategy to control phytoplankton blooms in tributary bays via controlled releases from TGR. © 2012 Elsevier Ltd. Source

While Terrapene Carolina Carolina (Eastern Box Turtle) are found over a wide geographic range, they appear to select microhabitats based on the need for thermoregulation, minimization of water loss, and reproduction. Habitat selection and the activity patterns of Eastern Box Turtles in southwestern Virginia were studied in relation to short-term weather conditions and seasonal variation. Turtles were located using telemetry 36% of the time in the interior of mature forest habitats, 23% in edge habitats, 18% in fields, 7% in a 22-year-old Pinus strobus (Eastern White Pine) plantation, 7% in forest canopy gaps, 5% in a 4-year-old clearcut, and 4% in streams. We observed a seasonal shift in habitat use, with more turtles using mature forest habitat compared to other habitat types in all months, except for May when 47% of all turtles were located in edge habitat. Also, Eastern Box Turtles often selected canopy gaps within forests during the fall, and females moved from forests to recent clearcuts during the nesting season, which accounted for a larger home-range size. As expected, turtle activity was lower during hot, dry periods in midsummer and decreased gradually during the autumn with decreasing temperature. Rainfall increased turtle activity, especially when following prolonged dry periods. Source

Religious contexts have traditionally been understood as protective for a variety of psychosocial health outcomes. However, the generalizability of these findings to youth who identify as lesbian, gay, bisexual, transgender or queer (LGBTQ) is questioned due to denominational teachings on same-sex attractions and sexual behavior. Eight adolescents (15-17 years) and 11 young adults (19-24 years) who identify as LGBTQ raised in Christian religious affiliations (16 participants raised in the Church of Jesus Christ of Latter Day Saints, 2 participants raised Catholic and 1 participant raised Presbyterian) participated in individual in-depth interviews, journal writings, and focus groups to provide greater insight into the lived experiences of LGBTQ individuals raised within a Christian religious environment. Findings suggest the religious context is related to both positive and negative outcomes. Eight themes are explored using participant's own words and experiences. Directions for future research and implications are discussed. © 2012 The Foundation for Professionals in Services for Adolescents. Source

Largemouth bronze gudgeon (Coreius guichenoti), a fish species once abundant in the Yangtze River, has been rapidly declining in recent years. One important factor, among many, is the interruption of the free-flowing rivers by dams. To obtain data that can be applied to the design of an effective fishway for C. guichenoti and other species in the fish community, a laboratory study of juvenile C. guichenoti's swimming ability and energetics was conducted in a flume-type respirometer equipped with a high-speed video camera system to record swimming behavior. The critical swimming speed (U crit), standard metabolic rate (SMR), and maximum metabolic rate (MO 2,max) were determined during steady swimming at four water temperatures (10, 15, 20, and 25°C). A power function accurately describes the relationship between oxygen consumption rate (MO 2) and swimming speed (U) at the four temperatures. The U crit, SMR, MO 2,max, and metabolic scope increased with increasing temperature. The relationship between cost of transport (COT) and U was characteristically inverse bell-shaped, with minimum COT at U opt = 4.5-5.0 body lengths per second (bl sec -1). This investigation provides data on the swimming ability of C. guichenoti that will add to the basic science required for fishway design. © 2012 WILEY PERIODICALS, INC. Source

Water consumption acutely reduces meal energy intake (EI) among middle-aged and older adults. Our objectives were to determine if premeal water consumption facilitates weight loss among overweight/obese middle-aged and older adults, and to determine if the ability of premeal water consumption to reduce meal EI is sustained after a 12-week period of increased water consumption. Adults (n = 48; 55-75 years, BMI 25-40kg/m 2) were assigned to one of two groups: (i) hypocaloric diet 500ml water prior to each daily meal (water group), or (ii) hypocaloric diet alone (nonwater group). At baseline and week 12, each participant underwent two ad libitum test meals: (i) no preload (NP), and (ii) 500ml water preload (WP). Meal EI was assessed at each test meal and body weight was assessed weekly for 12 weeks. Weight loss was ∼2kg greater in the water group than in the nonwater group, and the water group (Β = 0.87, P 0.001) showed a 44% greater decline in weight over the 12 weeks than the nonwater group (Β = 0.60, P 0.001). Test meal EI was lower in the WP than NP condition at baseline, but not at week 12 (baseline: WP 498 ± 25kcal, NP 541 ± 27kcal, P = 0.009; 12-week: WP 480 ± 25kcal, NP 506 ± 25kcal, P = 0.069). Thus, when combined with a hypocaloric diet, consuming 500ml water prior to each main meal leads to greater weight loss than a hypocaloric diet alone in middle-aged and older adults. This may be due in part to an acute reduction in meal EI following water ingestion. © 2009 The Obesity Society. Source
