资源简介:
Relationships between different measures of stability are not well
understood in part because empiricists and theoreticians tend to measure
different aspects and most studies only explore a single form of
stability. Using time-series data from experimental plankton communities,
we compared temporal stability typically measured by empiricists
(coefficient of variation of biomass) to stability measures typically
measured by theoreticians derived from the community matrix (asymptotic
resilience, initial resilience, and intrinsic stochastic invariability)
using first-order multivariate autoregressive models (MAR). Community
matrices were also used to derive estimates of interaction strengths
between plankton groups. We found no relationship between temporal
stability and stability measures derived from the community matrix. Weaker
interaction strengths were generally associated with higher stability for
community matrix measures of stability but were not consistently
associated with higher temporal stability. Temporal stability and
stability measures derived from the community matrix stability appear to
represent different aspects of stability reflecting the
multi-dimensionality of stability.
