A Comparison Of Spatial Learning And Memory Capabilities In Intertidal Gobies, Gemma E. White, Culum Brown
A Comparison Of Spatial Learning And Memory Capabilities In Intertidal Gobies, Gemma E. White, Culum Brown
Culum Brown, PhD
For the majority of animals, the ability to orient in familiar locations is a fundamental part of life, and spatial memory allows individuals to remember key locations such as food patches, shelter, mating sites or areas regularly occupied by predators. This study determined if gobies collected from rocky platforms and sandy beaches differ in their ability to learn and memorise the locations of tide pools in a simulated rocky intertidal zone. Intertidal rock pool gobies show acute homing abilities and, therefore, should be expected to display superior learning and memory capabilities. In contrast, it is unlikely that natural selection would …
Cue Choice And Spatial Learning Ability Are Affected By Habitat Complexity In Intertidal Gobies, Gemma E. White, Culum Brown
Cue Choice And Spatial Learning Ability Are Affected By Habitat Complexity In Intertidal Gobies, Gemma E. White, Culum Brown
Culum Brown, PhD
Variation in the structural complexity of a habitat is known to have significant affects on the evolution of different populations and can shape behavior, morphology, and life-history traits. Here, we investigated whether habitat complexity influences a species’ capacity for spatial learning and cue choice by comparing the performance of 4 goby species from 2 contrasting habitats in a spatial task. Gobies were collected from dynamic, homogenous sandy shores and stable, spatially complex rock pool habitats. We trained fish to use a T-maze to find a hidden reward and asked whether they used local visual landmarks or body-centered methods for orientation …
