Abstract

   To understand resource partitioning, essentially a community phenomenon, we
   require a holistic theory that draws upon models at the individual and population
   level. Yet some investigators are still content mainly to document differences
   between species, a procedure of only limited interest. Therefore, it may be
   useful to conclude with a list of questions appropriate for studies of resource
   partitioning, questions this article has related to the theory in a preliminary
   way. 1) What is the mechanism of competition? What is the relative importance of
   predation? Are differences likely to be caused by pressures toward reproductive
   isolation? 2) Are niches (utilizations) regularly spaced along a single
   dimension? 3) How many dimensions are important, and is there a tendency for more
   dimensions to be added as species number increases? 4) Is dimensional separation
   complementary? 5) Which dimensions are utilized, how do they rank in importance,
   and why? How do particular dimensions change in rank as species nuimber
   increases? 6) What is the relation of dimensional separation to difference in
   phenotypic indicators? To what extent does the functional relation of phenotype
   to resource characteristics constrain partitioning? 7) What is the distance
   between mean position of niches, what is the niche standard deviation, and what
   is the ratio of the two? What is the niche shape?
