But, Tilman’s (1982) hypothesis suggested that habitat heterogeneity increases with productivity to a certain point only after which it decreases. military intelligence jobs near me

"WebProductivity may be measured by density, survival, growth and movement to adult habitat (Beck et al. 2001). There are two general models for the location of juvenile habitats within the total range for a species which reflect life history strategies of the species. These are the Classic Concept: Juveniles and Adults in separate habitats. " - Species productivity hypothesis
