Flexibility in behavior can increase the likelihood that a forager may respond optimally in a fluctuating environment. Nevertheless, physiological or neuronal constraints may result in suboptimal responses to stimuli. We observed foraging workers of the giant tropical ant (also referred to as the “bullet ant”), Paraponera clavata, as they reacted to liquid solutions with varying concentrations of sugar and protein. We show that when protein/sucrose concentration is high, many bullet ants will… 
The palatability of Neotropical poison frogs in predator-prey systems: do alkaloids make the difference?
TLDR
It is inferred that amphibian secretions are attractive to invertebrate predators, but that this attraction is overridden when unpalatable alkaloid-based chemical defenses are present.
Morphology of the mandibular gland of the ant Paraponera clavata (Hymenoptera: Paraponerinae)
TLDR
The mandibular gland of P. clavata is described, which is composed of a reservoir connected to a cluster of Type III secretory cells with cytoplasm rich in mitochondria and lipid droplets, similar to that of other ants.
The contribution of neurodegenerative diseases to the modelling of semantic memory: A new proposal and a review of the literature
TLDR
An attempt is made to interpret the most relevant phenomena in the light of a new model of semantic memory, which comprises a language-based component, which supports the ability to establish reliable token vs. type relationships in the service of propositional thinking.

Diversity of speed-accuracy strategies benefits social insects
TLDR
There is consistent within-colony variance between honeybee workers in their speed-accuracy approach in a flower discrimination task and that varying the proportion of rewarding flowers changes the relationship between foraging strategy and rate of nectar collection.
Temperature and forager body size affect carbohydrate collection in German yellowjackets, Vespula germanica (Hymenoptera, Vespidae)
TLDR
Results from this study suggest that in yellowjacket colonies, foragers can collect and bring disproportionately more food back to the nest during the warmest days of the summer, a time of year when this pest species reaches peak population size during its annual colony cycle.
Communal Nutrition in Ants
TLDR
It is shown that foraging ants can solve nutritional challenges for the colony by making intricate adjustments to their feeding behavior and nutrient processing, acting both as a collective mouth and gut.
Graded recruitment in a ponerine ant
TLDR
The giant tropical ant, Paraponera clavata, exhibits graded recruitment responses, depending on the type, quantity, and quality of a food source, which represents one of the evolutionary transitions from the independent foraging activities of the primitive ants to the highly coordinated cooperative foraging Activities of many “higher” ants.
Seasonality Directs Contrasting Food Collection Behavior and Nutrient Regulation Strategies in Ants
TLDR
It is suggested that varied seasonal food collection behaviors and nutrient regulation strategies may be an adaptation that allows long-lived animals to meet current and future nutrient demands when nutrient-rich foods are abundant (e.g. spring and summer), and to conserve energy and be metabolically more efficient when nutritionally balanced foods are less abundant.
Foraging energetics of the ant, Paraponera clavata
TLDR
It is suggested that variation in individual B/C ratios may explain why the foraging behavior of Paraponera but not Pogonomyrmex appears sensitive to foraging costs.
Discrimination and preferences for pollen-based cues by foraging honeybees, Apis mellifera L.
TLDR
The results suggest that individual honeybee foragers do not discriminate among pollen sources based on intrinsic differences in quality, but instead evaluate cues that may increase their efficiency of collection and recruitment to such a food resource.
Placing an Omnivore in a Complex Food Web: Dietary Contributions to Adult Biomass of an Ant1
TLDR
The conclusion that omnivory is a key to supporting this species' biomass in Neotropical wet forests is supported, thanks to the importance of nectar as a source of metabolic carbon in adult worker biomass.
Mass recruitment to nectar sources inParaponera clavata: A field study
TLDR
Paraponera clavata foragers employ a trail pheromone and activation within the nest to obtain mass recruitment to simulated nectar sources and leave colonies in a temporal sequence that suggests social facilitation.
The influence of pollen quality on foraging behavior in honeybees (Apis mellifera L.)
TLDR
Overall, the results indicate that honeybees respond to deficiencies in the quantity or quality of their pollen reserves by increasing the gross amount of pollen returned to the colony, rather than by specializing in collecting pollen with a greater protein content.
