Individual and sex differences in the provisioning calls of European bee-eaters

摘要: Continuous input models of the ideal free distribution usually assume that resources are consumed immediately they enter a patch. This paper presents constant continuous in which this assumption is relaxed, so predictions can be made about standing crops and density relationship prey mortality caused by consumers. These suggest that: (1) matching rule not dependent on patch, holds whether or there interference competition but when an alternative source mortality; (2) exploitation fundamental to model. Whether occurs determined experimental situations measuring patches with different resource rates; (3) represent 'snapshot' time from either depletion models; (4) independent absence because all have same crop resources. When between consumers dependent, unless extremely strong. [KEYWORDS: INDIVIDUAL DECISIONS; PATCHY ENVIRONMENT; PREDATORS; STRATEGY]
