报告内容简介：
A seed shadow is the main outcome of the interaction between plants and frugivores. Thus, the study of seed shadows is an integrating approach to plant-frugivore interactions that deserves careful thinking. Yet we know very little about the fine details of seed shadows. In this talk I integrate different views of seed shadow analysis and explore the consequences of seed shadow structure in terms of spacing and gene flow patterns. I showcase new techniques to address the problem of quantifying the extent and reach of long-distance dispersal events and the genetic signatures of frugivore-mediated seed dispersal. A key aspect is that extinctions of dispersal services would impact plants mobility and regeneration, leaving lasting effects on spatial patterns, genetic structure, population isolation, and dispersal limitation. Long-distance dispersal events are particularly significant, and their collapse could have serious consequences for plant populations. Understanding seed shadows is crucial for studying plant responses to fragmentation, gene flow, and the survival of isolated populations. It will also shed light on the ecological and genetic impacts of long-distance dispersal, which may be more frequent and widespread than previously thought.
