Using a global model of continental water balance, forced by interannual variations in precipitation and near-surface atmospheric temperature for the period 1981-1998, we estimate the sea-level changes associated with climate-driven changes in storage of water as snowpack, soil water, and ground water; storage in ice sheets and large lakes is not considered. The 1981-1998 trend is estimated to ...

ha or more. Our results indicate that the 50-ha BCI plot lost a significant amount of 20 biomass (−0.8±2.2Mgha−1 yr−1) over the past decade (2000–2010). Over the entire island and during the same period, mean AGB change is −0.4±3.7Mgha−1 yr−1. Old growth forests lost biomass (−0.7±3.5Mgha−1 yr−1), whereas the secondary forests gained biomass (+0.4±3.4Mgha−1 yr−1). Our analysis demonstrates that...

The aim of the present study was to evaluate airway disease progression assessed by chest radiology, expiratory interrupter resistance (Rint,exp) and spirometry in young children with cystic fibrosis (CF) over a 3-yr period. Two chest radiographs combined with two R(int,exp) measurements were performed with a 3-yr interval in 21 preschool children (age (mean+/-sd) 3.2+/-0.9 yrs) and 30 schoolch...

Plasma dehydroepiandrosterone (DHEA) decreases ~80% between ages 25 and 75 yr. In a preliminary study, we found that 6 mo of DHEA replacement improved insulin action in elderly individuals. The purpose of the present larger, randomized double-blind study was to determine whether a longer period of DHEA replacement improves glucose tolerance. Fifty-seven men and 68 women aged 65 to 75 yr were ra...

Reproductive output by the Florida-endemic scrub hickory (Carya floridana Sargent) was studied over a 28-yr period in three south-central Florida vegetation associations: southern ridge sandhill, sand pine scrub, and scrubby flatwoods. The objectives were to describe multi-annual patterns of variation in nut production, identify factors involved in this variation, and investigate differences in...

BACKGROUND Obesity is a growing problem worldwide and can often result in a variety of negative health outcomes. In this study we aim to apply partial least squares (PLS) methodology to estimate the separate effects of age, period and cohort on the trends in obesity as measured by body mass index (BMI). METHODS Using PLS we will obtain gender specific linear effects of age, period and cohort ...

In the present study, population characteristics of Thunnus albacares were evaluated by sampling at five fish landing sites in the northern Oman Sea including Beris, Ramin, Pozm, Konarak and Jask from March 2017 to March 2018. The biometric analysis was performed on more than twenty-six thousand fish. Population dynamic parameters were calculated including infinite length (L∞=171 cm), growth co...

Abstract In this work, we present 8523 pairs of R -band optical photometry observations for the quasar 3C 454.3 made during period 2006 October–2018 February on 70 cm meniscus telescope at Abastumani Observatory, Georgia, to study its intraday variabilities (IDVs) and long-term variations, have come following results. (1) We detected 10 outbursts, a ? = 3.825 mag variation, some IDVs. The IDV t...
