Models tailored to incorporate organism-specific temporal scales are important when modelling species which respond to fluctuations in resource availability following short-term weather events.
A number of factors could potentially have confounded the brain-migration relationship, including the degree of seasonality in the environment, the extent to which the habitat buffers individuals from climatic conditions, the temporal fluctuations in resource availability and intrinsic features of the species related to energetic demands, developmental periods and social behavior [2].
Such fluctuations in resource availability have been reported to promote the invasibility of exotic invasive species (Davis and Pelsor 2001; Li and Stevens 2012; Mata et al. 2013).
This study extends previous work on the effects of environmental heterogeneity [ 13- 15, 19, 26, 28, 29, 61] by focusing specifically on the effect of temporal fluctuations in resource availability on population divergence.
For example, Einarsson and others (2002) saw that fluctuations in resource availability and inter-specific competition led to multi-year cycles in the abundance and body size of emerging chironomids in an Icelandic lake, although the authors observed that the fluctuations were ultimately driven by climatic cycles.
If variation in resource availability is large, diversity-based measures that ignore this availability may be highly misleading [ 22, 23].
When resource availability is not controlled, larger individuals may have larger components, driving a correlation between components due, in part, to variation in resource availability.
One cause for changes in abundance may be changes in resource availability [27].
(iii) Metabolic signatures and key metabolites reveal changes in resource availability at increasing plant diversity.
Differences in resource availability and quality also exist across institutions.
Substantial differences in resource availability exist across provinces.
