ISOLATION BY CHOICE

Sequential mate choice and sexual isolation in threespine stickleback species.

Sequential mate choice strategies predict how females should alter their choosiness based on the availability of attractive males. There are many studies on sequential mate choice within species, but few have asked whether females apply these strategies to interactions between species and how these strategies may affect hybridization. We tested how previous interactions with conspecific and het...

Dimensionality of mate choice, sexual isolation, and speciation.

Multiple cues, across multiple sensory modalities, are involved in mate choice in a wide range of animal taxa. This multiplicity leads to the prediction that, in adaptive radiations, sexual isolation results from divergence in multiple dimensions. However, difficulties in directly measuring preferences and detecting multiple effects limit our ability to empirically assess the number of independ...

Choice by Iterative Elimination

Motivated by real life decision problems, we model a boundedly rational choice procedure, called choice by iterative elimination, where an alternative might not be compared by all available alternatives. Our decision maker continues her limited search until she finds an alternative which is optimal within its consideration set. We study properties of this procure and provide a full characteriza...

Choice by sequential procedures

We propose a rule of decision-making, the sequential procedure guided by routes, and show that three influential boundedly rational choice models can be equivalently understood as special cases of this rule. In addition, the sequential procedure guided by routes is instrumental in showing that the three models are intimately related. We show that choice with a status-quo bias is a refinement of...
