In the hypothalamic supraoptic nucleus, changes in the astrocytic coverage of synapses under different physiological conditions result in changes in the ambient levels of d-serine released by astrocytes and its availability for NMDAR activation, thus influencing NMDAR-mediated synaptic responses (Panatier et al., 2006).
At the same time, its familiar and ritualistic nature reduces its availability for conscious examination.
The Bonney Upwelling has been shown to influence the breeding success of fur seals in the subsequent summer (i.e. cascade effect on nutrients; Gibbens and Arnould, 2009) and, thus, may influence prey availability for the Australasian gannet.
However, D-mannose and L-galactose are also involved in other biosynthetic pathways such as the synthesis of structural components, which may influence their availability for incorporation into Asc and downstream metabolites.
Household size as a proxy to labor availability may influence positively as its availability reduces the labor constraints (Teklewold et al. 2006).
We therefore tested the influence of food availability for the hive on the learning behaviour of bees.
For instance, the care of routine elective postoperative patients during weekdays could influence ICU bed availability for transfer patients and lead to shifting their admissions to the weekend.
Navarretia leucocephela have been found to increase reproduction in the absence of competitors, especially in the centre parts of vernal pools (Emery et al. 2009); this could also influence the nutrient availability for Dodder.
Mobility was another strategy used to cope with drought, because Bokspits area exhibits spatial vegetation heterogeneity between sand dunes, which influences forage availability for grazing animals (Scoones [1995]).
Variability in precipitation influences habitat availability for Ae. aegypti and Ae. albopictus larvae and pupae.
Growth is strongly influenced by light availability for canopy species in the lower canopy and subcanopy levels, while trees at the canopy level of inherently faster growing species usually reach larger sizes and are more responsive to light, with slower growing species occurring below faster growing species and vice versa (Seydack et al. 2011).
