Protective behavior or ‘true’ tool use? Scrutinizing the tool use behavior of ants [PDF]

Ecology and Evolution, 2020
In the genus Aphaenogaster, workers use tools to transport liquid food to the colony. During this behavior, ants place or drop various kinds of debris into liquids or soft food, and then, they carry the food‐soaked tools back to the nest.

Surfactant affects the tool use behavior of foraging ants

Ecotoxicology and Environmental Safety, 2022
Surfactants are commonly used in detergents, soaps and agrichemical products. After use, the residual surfactants can be dispersed into environmental compartments, directly or indirectly affecting aquatic and terrestrial organisms.

Development of a control task for clarifying the neural mechanisms underlying tool-use behavior in rats (Rattus norvegicus) [PDF]

MethodsX, 2019
Many studies on non-human animals have attempted to investigate the neural mechanisms underlying tool-use behavior. However, previous studies showed considerable non-tool-use-specific differences between tool-use and control tasks.

Potential Tool Use by Wolves (Canis lupus): Crab Trap Pulling in Haíɫzaqv Nation Territory [PDF]

Ecology and Evolution
The cognitive abilities of canids are increasingly recognized, though insights from noncaptive populations are comparatively rare. Recently, recurring damage to crab traps used by Haíɫzaqv Nation Guardians to control a European Green Crab invasion was ...

The basal ganglia mediate the inter-hemispheric transfer of complex tool-use skill [PDF]

iScience
Summary: Motor skills learned in one hand generalize to the other hand via plastic changes in motor systems. Such “intermanual transfer” may arise during complex tool-use learning, but its neural underpinnings remain unknown. Using resting-state fMRI, we

Black holes and random matrices [PDF]

Journal of High Energy Physics, 2017
We argue that the late time behavior of horizon fluctuations in large anti-de Sitter (AdS) black holes is governed by the random matrix dynamics characteristic of quantum chaotic systems.

Atypical tool and object use in wild immature chimpanzees reveals developmental pathways to innovation [PDF]

Scientific Reports
Innovation drives cultural evolution, yet little is known about its developmental origins or the role of immature individuals in generating novel behaviors. We examined 67 object uses by 36 infant and juvenile chimpanzees (Pan troglodytes schweinfurthii),

Use of the Behavior Assessment Tool in 18 Pilot Residency Programs

JBJS Open Access, 2020
Update. This article was updated on March 17, 2022, because of previous errors on pages 1, 4, 5, 6, and 7. In the Abstract, Results, and Discussion sections, the specificity of the ABOS Behavior Assessment Tool that had read “57%” and “57% (95% CI 52% to

pyAutonomousAgent: An Academic Tool for Modeling Autonomous Agent Behaviors Using Behavior Trees

Journal of Aerospace Technology and Management
Computer simulations have been applied in several areas. Non-player characters in computer simulations are autonomous agents. An autonomous agent receives information from the simulated environment, processes this information, and estimates a situation ...

Artificial Termite-Fishing Tasks as Enrichment for Sanctuary-Housed Chimpanzees: Behavioral Effects and Impact on Welfare

Animals, 2021
Artificial termite-fishing tasks are a common enrichment for captive great apes, promoting species-typical behaviors. Nonetheless, whether these activities are linked to changes in other behaviors and whether these changes persist over time has seldom ...
