Relations Among Spatiotemporal Heterogeneity, Population Abundance, and Variability in a Desert,e variable in organism abundance (e.g., Sousa, 1984). In the literature there are discrepancies as to the usage of the terms heterogeneity and variability (see Chapter 1); therefore we define our usage of the terms. . refers to composition of parts of different kinds, and . indicates changes in values of one kind (.).

The different abilities of species to tolerate burial, inundation and competition create vegetational gradients that are correlated with proximity to the shore (e.g. Milne and Forman, 1986). Thus each location within the landscape contains a subset of the species pool. The composition of

However, ecological systems are heterogeneous, and much information may be lost if the variance of a data set is ignored. This chapter shows that a specific prediction of hierarchy theory can be

Quality Challenges in an Agile Team, become clear that even if each city meets clean air and water standards for human health the regional ecosystems may be degraded. It is thus necessary to monitor and manage the environment on a regional or even global basis. At this scale, however, heterogeneity of all types becomes almost overwhel
