The aim of this study was to investigate the long-term effects of subchronic exposure to sublethal levels of nitrite, ranging from 15 to 130 mg l-1 NO2-, on growth in aquarium fish Danio rerio. The juvenile growth test according to OECD 215 was used in the experiments. Fish weight was measured at the beginning of the experiment and then using the same method, fish weight was observed 28 days after fish stocking. Compared to the control, growth suppression was detected from the concentration of 73 mg l-1 NO2- (P < 0.05) and a significant inhibition of fish body growth was shown from 130 mg l-1 NO2- (P < 0.01). An exponential relationship between nitrite concentrations and specific growth rate (R2 = 0.896) was detected.

Research plots in a wheat–wheat–fallow rotation at Indian Head, Sask., were sprayed annually with 2,4-dichlorophenoxy-acetic acid (2,4-D) for 36 consecutive years. Two species susceptible to 2,4-D, Chenopodium album L. and Thlaspi arvense L., were dominant in these plots. From 1981 to 1983, C. album and T. arvense seedlings that emerged during four periods of the growing season were marked and their mortality, seed production, and size recorded. From these data and other studies, 10 ways in which C. album and T. arvense managed to survive herbicide application were identified. These are intermittent germination, herbicide tolerance, small size of late-emerging seedlings, short life cycle, hardiness, failure of control practices, long-term dormancy, seed dispersal, viability of immature seeds, and winter annual life cycle of T. arvense.

Short And Long Term

Analyzing the British Election Study from 1964 to 2010, we examine the influence of electoral context on turnout, focusing on the closeness of elections in terms of lagged seat and constituency-level winning margins. Using cross-classified multilevel models to account for individual and contextual factors and disentangle life cycle, cohort- and election-specific effects, we find that closeness strongly affects voting behavior, particularly among new electors. Widening seat margins in British elections over the last decades have had a persistent impact on turnout. Respondents who faced less competitive environments when young are more likely to abstain in subsequent elections than those reaching voting age after close-fought races. We conclude that variations in competitiveness have had both short- and long-term effects on turnout.

Seismic Resilience

<p>The life-cycle seismic resilience of aging bridges and road transportation networks is investigated considering the long-term effects of bridge structural deterioration and network upgrading interventions under uncertainty. The proposed methodology is applied to a highway network with spatially distributed reinforced concrete (RC) bridges exposed to chloride-induced corrosion and different earthquake scenarios. A new road segment including a bridge is added over the lifetime to strengthen the network connectivity and improve the system resilience. The results show the detrimental effects of structural deterioration at the network scale and the benefits of infrastructure investments for network upgrading to enable long-term resilient infrastructures.</p>
