Forgetting And The Value Of Social Information, Benjamin James Abts
Forgetting And The Value Of Social Information, Benjamin James Abts
Theses
Information is everywhere in nature, however it can be deceitful or incorrect, so not all information should be used. Foraging pollinators utilize variable and ephemeral resources so learning about patch quality and nectar replenishment rates are essential to success and survival. However, remembering information after it is no longer relevant is not advantageous. It has been theorized that a pollinator’s memory should reflect their environment. Bumblebees are known to use both personal information (information gathered through trial and error) and social information (information gained through observations of or interactions with other animals or their products) in foraging decisions; however, it …

Predicting Choices In Bumblebees (Bombus Impatiens): Learning Rules And The Two-Armed Bandit, Isabel Lucia Rojas-Ferrer
Theses
Animals must make estimates about possible resources in order to choose the resource which will save them time and energy while conferring high energetic content. In order to make the most optimal decision, foragers must use various parameters to come up with an accurate estimate for each possible alternative. Learning rules allow us the possibility of analyzing which parameters animals may be using in order to make the best decision. We use compare known learning rules (i.e. Linear Operator Rule, Relative Payoff Sum Rule, Perfect Memory) and experimental data extracted from bumblebees (Bombus impatiens) subjected to a two armed bandit …
