Plant species specificity of ant–plant mutualistic interactions: Differential predation of termites by Camponotus crassus on five species of extrafloral nectaries plants

ES Calixto, D Lange, X Moreira, K Del‐Claro - Biotropica, 2021 - Wiley Online Library
There is increasing evidence that the outcomes of mutualistic interactions between ants and

Plants with extrafloral nectaries share indirect defenses and shape the local arboreal ant community

RF Moura, K Del-Claro - Oecologia, 2023 - Springer
Associational resistance (AR) is a positive interaction in which a plant suffers less herbivore
damage due to its association with a protective plant. Here, we evaluated whether plants …

Temporal variation in the effect of ants on the fitness of myrmecophilic plants: seasonal effect surpasses periodic benefits

K Monique, GR de Souza, ES Calixto, EA Silva - The Science of Nature, 2022 - Springer
Plants provide extrafloral nectar, which is a food resource taken by ants, especially
aggressive species that may act as plant guards. To our knowledge, no study has been …
