Exceptional Epiphyte Diversity on a Single Tree
An exhaustive survey of vascular epiphytes on a single mature canopy tree in a Costa Rican tropical premontane wet forest revealed an extraordinary level of epiphyte diversity. A total of 126 morphospecies representing at least 52 genera and 21 plant families were found growing epiphytically on the phorophyte (host tree), accounting for more than 1% of the entire vascular flora of Costa Rica. T...
متن کاملFunctional diversity of mesograzers in an eelgrass–epiphyte system
Historically, small invertebrate grazers in marine plant communities have been considered to be a relatively homogeneous group in their impact on ecosystem processes. However, recent studies propose that species composition is an important agent in determining grazer effects. We used four mesocosm experiments to test the biomass-specific and density-dependent effects of common mesograzers in te...

متن کاملSecondary foundation species as drivers of trophic and functional diversity: evidence from a tree-epiphyte system.
Facilitation cascades arise where primary foundation species facilitate secondary (dependent) foundation species, and collectively, they increase habitat complexity and quality to enhance biodiversity. Whether such phenomena occur in nonmarine systems and if secondary foundation species enhance food web structure (e.g., support novel feeding guilds) and ecosystem function (e.g., provide nursery...
متن کاملBiodiversity in agricultural landscapes: The effect of apple cultivar on epiphyte diversity
In natural systems, extended phenotypes of trees can be important in determining the species composition and diversity of associated communities. Orchards are productive systems where trees dominate, and can be highly biodiverse, but few studies have considered the importance of tree genetic background in promoting associated biodiversity. We tested the effect of apple cultivar (plant genetic b...
