- Multiple spectral channels in branchiopods. II. Role in light-dependent behavior and natural light environments
Summary: Branchiopod crustaceans use multiple spectral photoreceptor classes in their compound eyes for depth selection behavior in spectrally variable, dim light environments, suggesting simple visual neuroanatomy is used for luminance vision.
- Multiple spectral channels in branchiopods. I. Vision in dim light and neural correlates
Summary: Branchiopod crustaceans have simplified neuroanatomy in comparison to other pancrustaceans for processing color vision, yet they maintain four opsin-based spectral classes in their compound eyes.
- Photoreceptor specialization and the visuomotor repertoire of the primitive chordate Ciona
Highlighted Article: Ciona larvae looming-object escape behavior and negative phototaxis are mediated by different groups of photoreceptors and involve distinct, but overlapping, visuomotor pathways, and are characterized by circular and straight swim patterns, respectively.
- Environmental enrichment modulates the response to chronic stress in zebrafish
Summary: Behavioral and biochemical data show that environmental enrichment has positive effects on zebrafish subjected to unpredictable chronic stress.
- Multimodal sensorimotor system in unicellular zoospores of a fungus
Summary: The ability to respond to light and/or chemical gradients varies between Allomyces zoospores, a new model for sensory evolution; A. arbusculus behavior represents a multimodal, sensorimotor system in unicellular fungi.
- Potencies of effector genes in silencing odor-guided behavior in Drosophila melanogaster
Summary: Potencies of effector genes in silencing odor-guided behavior in Drosophila melanogaster depend on effector gene and behavioral paradigm.
- Mechanosensory signaling as a potential mode of communication during social interactions in fishes
Summary: Many fish social behaviors generate water movements that are detectable by the lateral line system of nearby conspecifics, suggesting that mechanosensory signaling may be an important mode of communication during social interactions such as reproduction, aggression and parental care.
- Ontogenetic changes in larval swimming and orientation of pre-competent sea urchin Arbacia punctulata in turbulence
Highlighted Article: Pre-competent, 6-armed larval urchins swim faster and are less stable in experimental turbulent flow than younger 4-armed larvae, suggesting a potential age/morphology-driven differential transport mechanism in ambient flow conditions.
- Phenotypic differences between the sexes in the sexually plastic mangrove rivulus fish (Kryptolebias marmoratus)
Highlighted Article: The sex-changing mangrove rivulus fish (Kryptolebias marmoratus) exhibits significant, sex-specific phenotypic differences, which may promote their transition between sexes.
- 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.
