Chlorophyll is an indispensable constituent of the photosynthetic machinery in green organisms. Bound by apoproteins of photosystems I and II, chlorophyll performs light-harvesting and charge separation. Due to the phototoxic nature of free chlorophyll and its precursors, chlorophyll synthesis is regulated to comply with the availability of nascent chlorophyll-binding apoproteins. Conversely, t...

We propose a method for reducing the error of the prediction of a quantity of interest when the outcome has missing values that are suspected to be nonignorable and the data are correlated in space. We develop a maximum likelihood approach for the parameter estimation of semi-parametric regressions in a mixed model framework. We apply the proposed method to phytoplankton data collected at fixed...

Satellites contribute significantly to environmental quality and public health. Environmental factors are important indicators for the prediction of disease outbreaks. This study reveals the environmental factors associated with cholera in Zhejiang, a coastal province of China, using both Remote Sensing (RS) and Geographic information System (GIS). The analysis validated the correlation between...

from genetic homogeneity). CORT showed the same pattern of dichotomy; of particular note, but contrary to our a priori prediction, blood CORT levels were higher in auklets that bred on a colony in which early chlorophyll-a bloom in local waters suggested good feeding conditions, than in auklets that bred on a colony with later local chlorophylla bloom. Also contrary to prediction, feather CORT ...

Chlorophyll protein accumulation in barley (Hordeum vulgare L.) chloroplasts is controlled posttranscriptionally by light-induced formation of chlorophyll a. The abundance of translation initiation complexes associated with psbA, psaA, and rbcL mRNAs was measured using extension and inhibition analysis in plants grown in the dark for 4.5 d and then illuminated for up to 16 h. Light-induced accu...
