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 ...

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 ...

Novel plant–insect interactions in an urban environment: enemies, protectors, and pollinators of invasive knotweeds

Ecosphere, 2019
Relationships between invasive plants and other species in their introduced ranges may facilitate or hinder the process of invasion. Fallopia japonica (Japanese knotweed), Fallopia sachalinensis (giant knotweed), and their hybrid Fallopia × bohemica ...

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 ...

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.

Facilitative Interactions among Extrafloral Nectary-bearing Plants, Ants, and Neighboring Vegetation in the Brazilian Cerrado

Sociobiology
Herbivory is a key plant–insect interaction that can have a negative impact on plant development. Some plants have evolved indirect defenses by attracting protective ants through extrafloral nectaries (EFNs).

Nectary use for gaining access to an ant host by the parasitoid Orasema simulatrix (Hymenoptera, Eucharitidae)

Journal of Hymenoptera Research, 2012
Eucharitidae is the only family of insects known to specialize as parasitoids of ant brood. Eggs are laid away from the host onto or in plant tissue, and the minute first-instars (planidia) are responsible for gaining access to the host through some form

Resilience through diversity: The potential of modelling species and variety interactions to enhance resilience of production systems

PLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 563-579, March 2026.
Agricultural production systems in the global North combine monocultures of specialised varieties and breeds with external interventions and inputs. Increasing the diversity of varieties, breeds and species may increase the system's resilience to external pressures through beneficial interactions.

Unraveling the Phenology of the Liana Marcgravia longifolia: Temporal Patterns and Climatic Cues

Biotropica, Volume 58, Issue 2, March 2026.
We monitored the reproductive phenology of the Amazonian liana Marcgravia longifolia J. F. Macbr (Marcgraviaceae) for 84 consecutive months in the Peruvian Amazon to quantify the timing, synchrony, and seasonality of flowering and ripe fruiting. Flower presence peaked in August with intermediate synchrony, while ripe fruit presence peaked in November ...

Phylogeny and historical biogeography of the Pachira sensu lato clade (Bombacoideae, Malvaceae) with a new infrageneric classification

TAXON, Volume 75, Issue 1, February 2026.
Abstract We explore phylogenetic relationships within the Pachira sensu lato clade (Bombacoideae, Malvaceae), test the monophyly of the genera Eriotheca and Pachira, and investigate their biogeographic history. The Pachira s.l. clade comprises ca. 72 species that traditionally have been placed in Eriotheca and Pachira. We sampled ca. 79% of its species
