Twelve-Day Reinforcement-Based Memory Retention in African Cichlids (Labidochromis caeruleus)
The formation of long-term memories for food sources is essential for the survival of most animals. Long-term memory formation in mammalian species has been demonstrated through a variety of conditioning tasks, however, the nature of long-term memory in fish is less known. In the current study, we explored whether African cichlids (Labidochromis caeruleus) could form memories for food-reinforce...
متن کاملSpeciation and Radiation in African Haplochromine Cichlids
The explosive radiation of cichlid fishes in the African Great Lakes has intrigued biologists for many decades. The faunas of these lakes are outstanding, both in species richness and in the composition of their fish fauna. Several of these lakes contain as many or even more fish species than all the rivers and lakes of Europe together (Lowe-McConnell 1987; Kottelat 1997). About 90% of the fish...
متن کاملHierarchical Memory-Based Reinforcement Learning
A key challenge for reinforcement learning is scaling up to large partially observable domains. In this paper, we show how a hierarchy of behaviors can be used to create and select among variable length short-term memories appropriate for a task. At higher levels in the hierarchy, the agent abstracts over lower-level details and looks back over a variable number of high-level decisions in time....
متن کاملOrigins of Shared Genetic Variation in African Cichlids
Cichlid fishes have evolved tremendous morphological and behavioral diversity in the waters of East Africa. Within each of the Great Lakes Tanganyika, Malawi, and Victoria, the phenomena of hybridization and retention of ancestral polymorphism explain allele sharing across species. Here, we explore the sharing of single nucleotide polymorphisms (SNPs) between the major East African cichlid asse...
