- Surpassing the subitizing threshold: appetitive–aversive conditioning improves discrimination of numerosities in honeybees
Highlighted Article: Appetitive–aversive differential conditioning enables honeybees to learn discrimination of quantities 1–10; however, classic appetitive conditioning does not allow bees to learn this same numerical task.
- Encoding lateralization of jump kinematics and eye use in a locust via bio-robotic artifacts
Summary: Encoding the jumping escape direction and surveillance orientation in young and adult Locusta migratoria as an adaptive consequence of prior exposure to directional-biased predator approaches generated by a biomimetic robot.
- Can honey bees discriminate between floral-fragrance isomers?
Summary: Discrimination of floral-fragrance isomers by bees is difficult, even under learning protocols that enhance discrimination; thus, isomers may not necessarily enhance plant odor diversity for pollinators.
- The effect of rearing environment on memory formation
Summary: Two lab-bred strains of Lymnaea stagnalis, derived from the same original population, demonstrate a difference in memory-forming ability, possibly due to environmental factors.
- Olfaction, experience and neural mechanisms underlying mosquito host preference
Summary: This Review discusses the environmental, neurobiological and genetic factors driving extreme host preference diversity and plasticity among the Culicidae, both within the life history of a mosquito and across evolutionary time-scales.
- Free-ranging dogs prefer petting over food in repeated interactions with unfamiliar humans
Summary: Free-ranging dogs are generally aversive towards making direct human contact for food. Interestingly, they show enhanced interactions with humans who provide them with positive social contact.
- Re-oxygenation after anoxia induces brain cell death and memory loss in the anoxia-tolerant crucian carp
Highlighted Article: Anoxia-tolerant crucian carp sustain brain cell death during early re-oxygenation, as well as impaired memory, although damage is transient and does not diminish learning ability.
- The effect of food quality during growth on spatial memory consolidation in adult pigeons
Summary: Food quality during development had long-lasting effects on memory in pigeons, with a moderate nutritional deficit improving spatial memory performance in a foraging context.
- Pigeons use distinct stop phases to control pecking
Summary: Pigeons control their pecking movements with two distinct stop phases that are dependent on stimulus size and type.
- Zebrafish learn to forage in the dark
Highlighted Article: Zebrafish are capable of foraging in the dark. Experimental manipulation indicates that this ability is acquired by larvae that learn to identify the flow generated by swimming prey.
