Social Aggression And Stress-Related Phenotype Formation In The Stress Alternatives Model, Tayler L. Modlin
Social Aggression And Stress-Related Phenotype Formation In The Stress Alternatives Model, Tayler L. Modlin
Honors Thesis
Stress is a universal reaction. Short-term stress can be viewed as positive, as it can promote survival and encourage positive behaviors; whereas chronic stress that is unpredictable can lead to health defects and emotional pathologies. The Stress Alternatives Model (SAM) was created with the purpose of testing decision-making during socially stressful situations. Over the course of a four-day experiment, test mice are exposed to periods of social stress caused by bites inflicted onto them by a larger aggressive mouse. As a response to these attacks, test mice exhibit an array of behaviors and ultimately develop one of two adaptive phenotypes: …

Infanticide has been widely documented throughout the animal kingdom, and has generally been viewed as an evolved, or adaptive behavior for the perpetrators. Infanticide motivated by increased sexual access to females with calves, or the elimination of potential genetic competition in the form of calf-directed aggression or infanticide, has been proposed for delphinids including killer whales, Indo-Pacific humpback dolphins, Guiana dolphins, and bottlenose dolphins. However, reports of intraspecific aggression towards bottlenose dolphin calves are relatively infrequent, and accounts of confirmed infanticide are rarer still. Reporting instances of intraspecific calf-directed aggression aids researchers to better understand the socio-behavioral context of these …
