Morphology, ontogeny and structure of the stipular nectaries in Caamembeca spectabilis (Polygalaceae) [PDF]

open access: yesActa Amazonica, 2016
Nodal glands are found in one third of the Polygalaceae genera and have valuable taxonomic, ecological and evolutionary significance. In Brazil, they occur in five of the eleven genera already registered.

Pericarpial nectary-visiting ants do not provide fruit protection against pre-dispersal seed predators regardless of ant species composition and resource availability. [PDF]

open access: yesPLoS ONE, 2017
Extrafloral nectaries can occur in both vegetative and reproductive plant structures. In many Rubiaceae species in the Brazilian Cerrado, after corolla abscission, the floral nectary continues to secret nectar throughout fruit development originating ...

The shared benefits of fallen fruits: A novel mechanism stabilizing a nursery pollination mutualism between Sambucus and kateretid beetles

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.

The predatory behavior of ants: an impressive panoply of morphological adaptations

open access: yesInsect Science, EarlyView.
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

Anatomy and Histology of the Midgut of Atopozelus opsimus (Heteroptera: Reduviidae)

open access: yesActa Zoologica, EarlyView.
ABSTRACT Atopozelus opsimus Elkins, 1954 (Heteroptera: Reduviidae) preys on forest and agricultural pests but also feeds on extrafloral nectar; however, its alimentary canal is poorly understood. The aim was to describe the anatomy and histology of the A. opsimus midgut. The alimentary canal of female and male A.

A Repertoire of Major Genes From Crop Wild Relatives for Breeding Disease‐Resistant Wheat, Rice, Maize, Soybean and Cotton Crops

open access: yesPlant Breeding, EarlyView.
ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.

Emerging Trends in Ant–Pollinator Conflict in Extrafloral Nectary-Bearing Plants

open access: yesPlants
The net outcomes of mutualisms are mediated by the trade-offs between the costs and benefits provided by both partners. Our review proposes the existence of a trade-off in ant protection mutualisms between the benefits generated by the ants’ protection ...
