| interhemispheric comparison of recruitment to intertidal communities: pattern persistence and scales of variation. | recruitment variation can be a major source of fluctuation in populations and communities, making it difficult to generalize results. determining the scales of variation and whether spatial patterns in the supply of individuals are persistent over time can provide insight into spatial generality and the application of conservation and metacommunity models. we examined these issues using eight-year-long data sets of monthly recruitment of intertidal mussels (mytilus spp., perumytilus purpuratus, ... | 2008 | 18543624 |
