Functional convergence of genomic and transcriptomic genetic architecture underlying sociability in a live-bearing fish

The paper investigates the genetic basis of sociability in guppies using quantitative genetics and transcriptomics, finding convergent genomic and transcriptomic signatures related to synaptic function and calcium signaling.

Lionfish Pterois volitans can see UV light: UV Vision in an Invasive Aquatic Predator

This study shows that lionfish can see UV light and reflect it, suggesting UV vision may aid in communication and predation.

Changes driven by the evolution of higher group polarization in the guppy are consistent across different predation pressures and associated with neuroanatomical changes

The paper shows that guppies selected for higher group polarization maintain this behavior under predation and exhibit neuroanatomical changes linked to improved sensory processing.

Jumping out of trouble: Evidence for a cognitive map in guppies (Poecilia reticulata)

This study shows guppies use spatial memory and environmental cues to direct jumps, using a cognitive map in familiar situations.

Where are they now? Tracking the Mediterranean Lionfish Invasion via Local Dive Centers

The paper tracks the spread of invasive Mediterranean lionfish using dive center reports, finding the invasion front moving west and north, exceeding previous models.

Rapid mosaic brain evolution under artificial selection for relative telencephalon size in the guppy (Poecilia reticulata)

This study shows that artificial selection on telencephalon size in guppies leads to changes in that brain region without affecting other regions, supporting mosaic brain evolution.

Rapid evolution of coordinated and collective movement in response to artificial selection

This study shows that artificial selection on guppies rapidly increases social coordination and collective movement traits.
