Leaf secretory structures in Ceiba (Malvaceae - Bombacoideae): ontogeny, anatomy and histochemistry [PDF]

Rodriguésia
The description of secretory structures in Malvaceae is controversial, and results in conflicting interpretations. Amid conflicting interpretations, therefore, the present study aims to describe the ontogeny diversity and histochemistry in Ceiba ...

From leaves to defenders: How the amount and dispersion of leaf damage affect extrafloral nectar production and ant‐mediated protection in wild cotton

Ecological Entomology, Volume 51, Issue 2, Page 395-404, April 2026.
Extrafloral nectar mediates interactions among plants, ants and herbivores; its contingency on damage amount and within‐plant uniformity is poorly understood. Here, we explore these factors in wild cotton (Gossypium hirsutum). Herbivory amount drove increases in extrafloral nectar induction per nectary, whereas within‐plant variability in damage ...

Ants Visiting the Post-Floral Secretions of Pericarpial Nectaries in Palicourea rigida (Rubiaceae) Provide Protection Against Leaf Herbivores But Not Against Seed Parasites

Sociobiology, 2013
Pericarpial nectaries (PNs) have frequently been treated in the literature as extrafloral nectaries (EFNs). This treatment is partly justified by their morphological and functional similarities in attracting bodyguard ants to protect the plant against ...

The role of habitat simplification and seasonality in shaping interactions between ants, plants and herbivores in a neotropical savanna

Ecological Entomology, Volume 51, Issue 2, Page 381-394, April 2026.
We evaluated how chronic anthropogenic disturbances (CAD) and seasonal variation influence interactions between ants and plants with extrafloral nectaries (EFN's), with emphasis on the responses of ants, herbivores, and plants. Ant and herbivore diversity remained stable across seasons in the preserved cerrado, whereas the pasture had higher ant ...

I Can See You: Temporal Variation in Ant Aggressiveness Towards Herbivores under Continuous Provision of High- or Low-quality Food Sources

Sociobiology, 2020
To reduce herbivory, plants bearing extrafloral nectaries interact with ants and attract them by providing food. As plant bodyguards, ants respond to the resource provision and, using their antennae, detect chemical messages from the host plants that ...

Individual-based ant-plant networks: diurnal-nocturnal structure and species-area relationship. [PDF]

PLoS ONE, 2014
Despite the importance and increasing knowledge of ecological networks, sampling effort and intrapopulation variation has been widely overlooked. Using continuous daily sampling of ants visiting three plant species in the Brazilian Neotropical savanna ...

Neglected Floral Visitors in the Galapagos Islands: Understanding the Structure of Ant‐Flower Interaction Networks

Journal of Applied Entomology, Volume 150, Issue 3, Page 321-332, April 2026.
ABSTRACT Ant‐flower interactions are prevalent in many ecosystems, yet their ecological significance remains poorly understood, particularly in isolated systems like the Galapagos Islands, where unique biotic assemblages create distinct interaction networks.

THE EXTRAFLORAL NECTARIES OF IPOMOEA LEPTOPHYLLA (CONVOLVULACEAE)

American Journal of Botany, 1980
Ipomoea leptophylla Torr. (Convolvulaceae) is a sprawling dry‐site morning glory with two types of extrafloral nectaries: foliar nectaries and nectaries on the outside of the sepals. Both are shown to greatly increase insect visitation to the plant. Ants visiting sepal‐surface nectaries significantly decrease flower damage caused by grasshoppers and ...

Foraging ants on the extrafloral nectaries repel nectar thieves but not the effective pollinator of Vigna luteola (Fabaceae) in a Mexican coastal sand dune

Sociobiology, 2018
While some studies have shown that ants that visit extrafloral nectaries may defend their host plants against potential herbivores, recent researches have shown that such ant-plant mutualism may be broken in some cases.

New Tools for Conservation Biological Control: Testing Ant-Attracting Artificial Nectaries to Employ Ants as Plant Defenders

Insects, 2020
Knowledge of the role of ants in many agroecosystems is relatively scarce, and in temperate regions the possibility to exploit ants as biocontrol agents for crop protection is still largely unexplored. Drawing inspiration from mutualistic ant−plant
