Assessment of assemblage‐wide temporal niche segregation using null models

摘要: Summary 1. Although time can be subdivided to promote species coexistence, quantitative examination of assemblage-wide temporal niche overlap has seldom been explored with appropriate null models. Because the sequential and continuous nature time, it requires a different kind randomization model than those used assess subdivision discrete non-sequential resources (e.g. food types microhabitats). 2. For two common indices (Pianka Czekanowski), we compared responses models newly developed (ROSARIO) levels autocorrelation, specialization coincidence activity. 3. qualitatively similar results characterized indices, differed depending on model. Temporal resolution data amount in an assemblage have large effects outcomes. ROSARIO is as powerful for analyses nominal unordered resources, but more ranked interval data, maintains empirical autocorrelation within species. 4. useful tool exploration patterns use that occur cyclical phenomena, such diel phases, yearly seasons, lunar tides climate oscillations.
