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.

Las plantas presentan relaciones mutualísticas con insectos a cambio del control de sus herbívoros u hongos patógenos; por medio de los domacios les ofrecen albergue y mediante la secreción de néctar de nectarios extraflorales les brindan alimento.

Presumed domatia are actually extrafloral nectaries on leaves of Anacardium humile (Anacardiaceae)
Presumed domatia are actually extrafloral nectaries on leaves ofAnacardium humile (Anacardiaceae), a species from the Brazilian savannah, is associated with foraging ants, which leads to the description of the structure of its leaves as domatia. However,

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

Extrafloral nectary–the sleeping beauty of plant science [PDF]
AbstractCotton is one of the most important cash crops, its growth season coincides with a high incidence of diverse groups of pests, leading to heavy use of pesticides. Recent identification of a signaling protein as a candidate regulator of cotton extrafloral nectary provides a new insight into the formation of sophisticated defense mechanisms in ...

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

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

Epidendrum denticulatum (Orchidaceae) produces nectar on the petioles of buds, flowers, and fruits (extrafloral nectaries) but no nectar is found on its flowers, and it is probably a deceptive species.

THE EXTRAFLORAL NECTARIES OF IPOMOEA CARNEA (CONVOLVULACEAE)
Ipomoea carnea (Convolvulaceae) possesses two types of extrafloral nectaries, located on the petiole and on the pedicel. These secrete a complex nectar containing sugars and amino acids. The insects attracted to the extrafloral nectaries are predominantly ants and they are relatively abundant throughout the year.
