However, a wide variety of factors can give rise to retention time variations.
In addition, the rise and retention of the C. lutrensis phenotype in the southern region of the transect superficially creates the appearance of native species displacement without any hybridization.
These findings indicate that the rise and retention of a single parental species' phenotype following an introduction event can mask a history of hybridization and can lead to the appearance of one species being displaced by another without hybridization.
The rise and retention of the C. lutrensis phenotype following an introduction event might therefore reflect both prezygotic and postzygotic reproductive advantages, where the benefits of increased fecundity and short generation time are buoyed by preferences for parental traits (Lande 1981; West-Eberhard 1983; Panhuis et al. 2001; Turelli et al. 2001).
"Under his leadership, student test scores rose significantly, retention increased and more than 60 faculty were hired during the past two years," said Matthew Goldstein, the CUNY chancellor.
Despite the rise in grade retention in poor areas in rural China recently, little work has been done to understand the impact of grade retention on the educational performance of students in these areas in rural China.
This impairment in integrin function could give rise to inadequate retention and/or positioning of MZ B cells and may explain the decreased MZ B-cell population.
For example, dietary folate deficiency (Spiegelstein et al. 2005) and/or dietary methyl donor deficiency significantly decreased total urinary As excretion, mainly due to lower DMA excretion; these diets also gave rise to increased retention of As in tissues, particularly in the liver and lungs (Tice et al. 1997; Vahter and Marafante 1987).
By acting on sarcolemmal NCX, the [Na+] rise then causes retention of intracellular Ca2+, which facilitates greater SR Ca2+ loading via SERCA, leading ultimately to enhanced SR Ca2+ release, and hence an increase in CaT amplitude (for convenience, defined here as an indirect stimulatory H + effect on the CaT).
Retention rises dramatically if you reread it one or two times.
