Effects of short‐ and long‐term enrichment on brain and behavior in Trinidadian guppies
Ethology, Volume 130, Issue 3, March 2024.Environmental enrichment often alters behavior in captive animals. Here, we exposed guppies either to short‐term (two week) or long‐term (birth through 12 weeks) enrichment and measured growth, brain size, and neophobic behaviors. Females responded more strongly overall to enrichment in both short‐ and long‐term.
