This study was conducted to provide a five-year database on the breeding seasonality and breeding biology of a central American cichlid fish Neetroplus nematopus, a biparental substratum-spawning cichlid that cares for its eggs, wrigglers, and fry for up to six weeks. A total of 503 breeding pairs were monitored for breeding success. breeding pairs of N. nematopus are sexually dimorphic in size, with females averaging 39% of male body mass. Fry emerged from 85% of nesting cavities. After three weeks, only 30% of the broods were present in the nesting cavity; these broods had a 30% survival rate, giving a 9% overall survival rate. Nineteen percent of the successful parents with three-week-old broods adopted foreign fry. A consistent unimodal breeding peak in December was observed for five years. This breeding peak differed dramatically from the bimodal breeding season 20 years found in the 1970s. The effects of extensive grenade fishing practices during the 1980s might have played a substantial role in the observed change. Grenade fishing stopped in 1991, and the number ofN. nematopus pairs increased by 136% from 1990 to 1995. With increased density of breeding fish, the breeding season for this species also expanded. The balance between divergent selection due to competition for breeding sites and stabilizing selection due to predation pressure on offspring is likely to mold the breeding season for N. nematopus and other cichlids of Lake Xilofi. We suggest that brood adoption and synchrony of breeding is a strategy to reduce predation on the parent＇s own young [current Zoology 56 （1）： 43-51 2010].

background: Trampoline use is one of the most common causes of recreational injury in children. In recent years, trampoline parks have grown in popularity and may be altering the spectrum of the trampoline-related injuries that occur. These parks create increased opportunity for injuries that appear uniquely different from accident patterns seen with home trampoline use. Recent work has suggested this may result in injuries occurring in greater frequency and with increased severity that may result in a greater need of hospital admission and procedural management by subspecialty services. case Series Presentation: This case series presents three such examples occurring after the opening of a trampoline park in our local community: 1) A displaced forearm fracture requiring closed reduction and orthopedic follow-up;2) An ankle fracture necessitating operative reduction and fixation;and 3) A facial injury with tooth avulsion prompting oral surgery consultation and endodontic follow-up. conclusions: These cases demonstrate the complexity and severity of injury that can occur from trampoline park participation and should serve to increase awareness among health care providers of these risks to provide appropriate parental counseling and advocate for preventative measures.

background： During late gestation the placental epithelial interface becomes highly folded, which involves changes in stromal hyaluronan. Hyaluronan is composed of glucoronate and N-acetyl-glucosamine. We hypothesized that supplementing gestating dams with glucosamine during this time would support placental folded-epithelial-bilayer development and increase litter size. In Exp. 1, gilts were unilaterally hysterectomizedovariectomized（UHO）. UHO gilts were mated and then supplemented daily with 10 g glucosamine（n = 16） or glucose（control, n = 17） from d 85 of gestation until slaughter（d 105）. At slaughter, the number of live fetuses was recorded and each live fetus and its placenta was weighed. Uterine wall samples adjacent to the largest and smallest fetuses within each litter were processed for histology. In Exp. 2, pregnant sows in a commercial sow farm were supplemented with either 10 g glucosamine or glucose daily from d 85 of gestation to farrowing. Total piglets born and born alive were recorded for each litter. In Exp. 3, the same commercial farm and same protocol were used except that the dose of glucosamine and glucose was doubled to 20 g/***： In Exp. 1, the number of live fetuses tended to be greater in glucosamine-treated UHO gilts（P = 0.098）.Placental morphometry indicated that the width of the folded bilayer was greater（P = 0.05） in glucosamine-treated gilts. In Exp. 2, litter size did not differ between glucosamine-and glucose-treated sows. However in Exp. 3, the increased dose of glucosamine resulted in a significant treatment by parity interaction（P ≤ 0.01）, in which total piglets born and born alive were greater in glucosamine treated sows of later parity（5 and 6）.conclusions： These results indicated that glucosamine supplementation increased the width of the folds of the placental bilayer and increased litter size in later parity, intact pregnant commercial sows.

The objective of this research was to determine what influence geometric design elements of roadway may have on driver behavior during the overtaking maneuver. This was part of a larger research effort to eliminate crashes （and the resulting fatalities and injuries） between bicycles and motorized vehicles. The data collection process produced 1151 observations with approximately 40 different independent variables for each data point through direct observation, sensor logging, or derivation from other independent variables. Prior research by the authors developed a means to collect real-time field data through the use of a bicycle-mounted data collection system. The collected data was then used to model lateral clearance distance be- tween vehicles and bicycles. The developed model confirmed field observations that the lateral clearance distance provided by drivers changes with vehicle speed and oncoming vehicle presence. These observations were presented by the authors previously. The model shows that driver behavior can be adjusted by the inclusion, or exclusion, of geometric elements. Evaluating roadways （or roadway designs） based on this model will enable stakeholders to identify those roadway segments where a paved shoulder would prove an effective safety countermeasure. This research will also enable roadway designers to better identify during the design phase those roadway segments that should be constructed with a paved shoulder.
