Overview

Field experiments demonstrate that ant presence increases fruit production in Declieuxia fruticosa, indicating multitrophic interactions enhance plant fitness.

Key Points

This study aims to examine how ants at post-floral nectaries affect fruit production and quality in Declieuxia fruticosa.
Conducted field experiments manipulating ant presence at post-floral pericarpial nectaries.
Measured fruit number, weight, width, and length.
Assessed stigma receptivity and pollen availability.
Evaluated the assemblage of floral visitors and herbivores.
Ant presence significantly increased fruit set and enhanced all measured morphological traits.
Fruits from plants with ants were on average 25% larger and 2.4 times heavier.
Ants reduced nectar thief frequency by 2.9 times and increased Apis mellifera visitation by 65%.
