- Color discrimination thresholds in a cichlid fish: Metriaclima benetos
Summary: Color discrimination thresholds of cichlids can be obtained through visually mediated tasks, enabling investigation of the role of vision in cichlid ecology, sexual selection and speciation.
- Feedback to the future: motor neuron contributions to central pattern generator function
Summary: Motor neurons relay signals from the brain and spinal cord to muscles that perform behaviors. However, studies across phyla indicate that motor neurons also contribute to the function of pattern-generating circuits.
- Acetoin is a key odor for resource location in the giant robber crab Birgus latro
Summary: Birgus latro is the biggest land-living crab – a solitary animal that sometimes accumulates at food sources. A single food odor, acetoin, is sufficient to govern this behavior.
- Anthropogenic noise and the bioacoustics of terrestrial invertebrates
Summary: We review the current literature on invertebrate bioacoustics and characteristics of anthropogenic noise to suggest a framework for understanding the potential impact of anthropogenic noise on terrestrial invertebrates.
- Food-derived volatiles enhance consumption in Drosophila melanogaster
Summary: Fruit flies integrate diverse olfactory and gustatory cues to guide feeding decisions, including situations in which animals are confronted with stimuli of opposite valence.
- Gut microbiota affects development and olfactory behavior in Drosophila melanogaster
Summary: Fruit flies raised on food enriched with one of their gut microbes change their preference for these microbes and their developmental rate depending on their specific microbe pre-exposure.
- Cyclic nature of the REM sleep-like state in the cuttlefish Sepia officinalis
Summary: Evidence suggests that cephalopods possess a sleep-like state that resembles behaviorally the vertebrate rapid eye movement sleep (REMS)-like state.
- Sleep regulates visual selective attention in Drosophila
Summary: Sleep manipulations specifically alter visual selective attention in fruit flies, without affecting behavioral responses to simple visual stimuli.
- Innate visual preferences and behavioral flexibility in Drosophila
Summary: An operant conditioning paradigm in a multiple-choice maze shows that innate visual preferences can be transiently modulated in Drosophila via optogenetic activation of NPF-expressing neurons.
- Carpenter ants use diverse antennae sampling strategies to track odor trails
Highlighted Article: High-resolution imaging of antennae reveals distinct patterns of sampling with non-redundant roles in odor tracking.
