Loss and gains in ant–plant interactions mediated by extrafloral nectar: fidelity, cheats, and lies
TLDR
It is proposed that ant–EFN bearing plant interactions serve an excellent and unique model to test the “Geographic Mosaic Theory” of coevolution providing a more clear view of how evolution has structured these plant–animal ecological networks.
Trait-mediated indirect interactions of ant shape on the attack of caterpillars and fruits
TLDR
Empirical evidence is presented that objects resembling ant shape on dummy caterpillars were able to repel visually oriented predators and it is shown that rubber ants on dummy fruits can repel potential fruit dispersers.
Variation in Sexual Expression in Jacaratia mexicana (Caricaceae) in Southern Mexico: Frequency and Relative Seed Performance of Fruit‐Producing Males
TLDR
The existence of fruiting males in the dioecious tropical tree Jacaratia mexicana (Caricaceae) is reported, and it is suggested that fruiting Males will not replace female plants in natural populations.
Morphological variation in the flowers of Jacaratia mexicana A. DC. (Caricaceae), a subdioecious tree.
TLDR
The restriction of sexual variation to male trees is consistent with the evolutionary path of dioecy from hermaphrodite ancestors through the initial invasion of male-sterile plants and a subsequent gradual reduction in female fertility in cosexual individuals, but further work is needed to confirm this hypothesis.
Fate of epiphytes on phorophytes with different architectural characteristics along the perturbation gradient of Sabal mexicana forests in Veracruz, Mexico.
Question: Vascular epiphytes and hemiepiphytes (E/HE) in neotropical forests account for a large fraction of plant richness, but little is known of how the interplay between phorophyte architectural
Foraging ants on the extrafloral nectaries repel nectar thieves but not the effective pollinator of Vigna luteola (Fabaceae) in a Mexican coastal sand dune
TLDR
It is shown that the effective pollinators of V. luteola present strategies that allow them to visit the flowers without being aggressively attacked by the ants that visit the extrafloral nectaries (EFNs), therefore, the presence of ants on plants could have a dual function: protecting plants against potential herbivores as well as, filtering flowers against nectar thieves.
