v1 v2 1 1 == 3.14 Compensatory growth == 2 2 3 Compensatory growth rate responses are modelled by setting the ‘feeding time adjustment rate’ ([ [Group info.htm|Group info]] form) to zero, so that simulated ''''Q/B'''' is allowed to vary with pool biomass (nonzero feeding time adjustment results in simulated organisms trying to maintain Ecopath base ''Q/B'' by varying relative feeding time). Net production is assumed proportional (growth efficiency) to ''Q/B'', whether or not this production is due to recruitment or growth. The ''Q/B'' increase with decreasing pool biomass is increased by decreasing vulnerability of prey to the pool ([[Vulnerabilities flow control.htm|Vulnerabilities]] form). In the extreme as vulnerability approaches zero (donor or bottom up control), total food consumption rate ''Q'' approaches a constant (Ecopath base consumption), so ''Q/B'' becomes inversely proportional to ''B''.3 Compensatory growth rate responses are modelled by setting the ‘feeding time adjustment rate’ ([wiki:GroupInfo Group info] form) to zero, so that simulated ''''Q/B'''' is allowed to vary with pool biomass (nonzero feeding time adjustment results in simulated organisms trying to maintain Ecopath base ''Q/B'' by varying relative feeding time).
