Journal ArticleDOI
Toxic cardenolides: chemical ecology and coevolution of specialized plant–herbivore interactions
TL;DR: While reviewing both the mechanisms and evolutionary ecology of cardenolide-mediated interactions, novel hypotheses are advanced and directions for future work are suggested.
Journal ArticleDOI
The evolution of antiherbivore defenses and their contribution to species coexistence in the tropical tree genus Inga
Thomas A. Kursar,Thomas A. Kursar,Kyle G. Dexter,John Lokvam,R. Toby Pennington,James E. Richardson,Marjorie G. Weber,Eric T. Murakami,Camilla Drake,Ruth C. McGregor,Phyllis D. Coley,Phyllis D. Coley +11 more
TL;DR: In an analysis of community assembly, it is found that Inga species co-occurring as neighbors are more different in antiherbivore defenses than random, suggesting that possessing a rare defense phenotype increases fitness.
Journal ArticleDOI
The phylogenetic distribution of extrafloral nectaries in plants.
TL;DR: Phylogenetic analyses strongly support the repeated gain and loss of EFNs across plant clades, especially in more derived dicot families, and suggest that EFNs are found in a minimum of 457 independent lineages.
Journal ArticleDOI
On the study of plant defence and herbivory using comparative approaches: how important are secondary plant compounds.
Anurag Agrawal,Marjorie G. Weber +1 more
TL;DR: The notion that plant primary metabolites are the principal determinants of herbivory (or the target of natural selection by herbivores) is not likely to be correct and the importance of secondary chemistry in plant defence may have been generally overstated in earlier research.
Journal ArticleDOI
Evolution in a Community Context: On Integrating Ecological Interactions and Macroevolution
Marjorie G. Weber,Catherine E. Wagner,Rebecca J. Best,Rebecca J. Best,Luke J. Harmon,Luke J. Harmon,Blake Matthews +6 more
TL;DR: It is argued that, despite inherent challenges associated with reconstructing historical processes, the interplay of ecology and evolution is central to the authors' understanding of macroevolution and community coexistence, and cannot be safely ignored in community and comparative phylogenetic studies.
