Physiological characteristics

The changes in spatial distribution of mineral resources and the morphological and physiological characteristics of the dominant plants have an effect on key ecosystem processes by affecting the timing of growth and... [Pg.353]

The existence of a species of tomato on the Galapagos Islands was first noted by Charles Darwin. Despite a moderate level of variation, Lycopersicon cheesmanii Riley is considered the only tomato species on the islands. All populations examined exhibited morphological and physiological characteristics that clearly... [Pg.248]

Ventricular premature depolarizations occur as a result of abnormal ventricular automaticity, as a result of enhanced activity of the sympathetic nervous system and altered electro-physiologic characteristics of the heart during myocardial ischemia and following myocardial infarction. [Pg.125]

Kirkwood, E., Nalewajko, C., and Fulthorpe, R.R., Physiological characteristics of Cyanobacteria in pulp and paper waste treatment systems, J. Appl. Phycol. 15, 324-335, 2003. [Pg.909]

Biochemical tests are usually performed after pure cultures have been obtained. The standard indole, methyl red, Voges-Proskauer, citrate, and litmus milk tests may be used to show important physiological characteristics. To study the functional diversity of bacteria, the utilization of carbohydrates, amines, amides, carboxylic acids, amino acids, polymers, and other carbon and nitrogen sources can be tested.28 Dilution-based most-probable number (MPN) techniques with phospholipid fatty acids as biomarkers have been employed for studying different bacterial species in lakes.40 The patterns of antibiotic resistance in bacteria isolated from natural waters have been useful for identifying sources of water pollution.34... [Pg.5]

Validation of the model. The O Flaherty Model was initially calibrated to predict blood, bone, and tissue lead concentrations in rats (O Flaherty 1991a), and subsequently modified to reflect anatomical and physiological characteristics in children (O Flaherty 1995a), adults (O Flaherty 1993) and Cynomolgus... [Pg.243]

IMP-S02 [49], and ECRD-1 [50], Many of these strains are similar in the mechanism of DBT desulfurization, but vary in terms of the desulfurization rate as well as physiological characteristics. [Pg.72]

The pig is widely used in research and testing since it shares many anatomical and physiological characteristics with humans. This makes it a unique and viable model for biomedical research. In fact, most relevant models have been reviewed in a series of technical proceedings and books in the last two decades (Swindle, 1998). [Pg.242]

Calcium absorption data are needed from animal and human subjects having similar nutritional and physiological characteristics and which have consumed identical calcium sources. [Pg.22]

PBPK modeling is the development of mathematical descriptions of the uptake and disposition of chemicals based on quantitative interrelationships among the critical biological determinants of these processes. These determinants include partition coefficients, rates of biochemical reactions and physiological characteristics of the animal species. The biological and mechanistic basis of the PBPK models... [Pg.731]

The different fibres have different properties, and different proportions are present in different individuals. The biochemical and physiological characteristics of the different fibres explain why some individuals are good sprinters whereas others are good endurance athletes. These differences are most marked in... [Pg.277]

Two major barrier systems separate the central nervous system from the circulation the BBB and the blood-cerebrospinal fluid barrier (B-CSF-B). These barriers have distinct morphological and physiological characteristics, according to their different tasks. Figure 2.1 highlights the salient features of both barrier systems. [Pg.27]
