Evaluation Of The Recreational Catch-And-Release Fishery For Golden Dorado Salminus Brasiliensis In Salta, Argentina: Implications For Conservation And Management, Tyler Gagne
Masters Theses
Golden dorado (Salminus brasiliensis, Cuvier, 1816) is increasing in popularity as a target for recreational anglers practicing catch-and-release (C&R) in northern Argentina and bordering countries. However, to date no research has looked at the potential social and ecological implications of growth in this recreational fishery. The first manuscript of this thesis assessed the consequences of C&R on golden dorado captured by anglers on the Juramento River in Salta, Argentina. This evaluation examined physical injury, physiological stress, reflex impairment, and short term post-release behavior to develop a clear set of evidence-based best practices for C&R. In addition, the Juramento …

Behavioral And Neural Mechanisms Of Impulsive Choice, Jesse Mcclure
Doctoral Dissertations
Impulsive choice is defined as the preference for a small immediate reward over a larger delayed reward. Individual variablity in impulsive choice correlates with many socially relevant behaviors. Although forms of impulsive choice have been studied in both behavioral ecology and psychology, the exchange of knowledge between these fields is just beginning. Drawing from both of these fields will improve our research methods allowing for a more detailed understanding of this complex behavior. Existing tasks to measure impulsive choice conflate the delay and quantity of the reward. To address this, I have drawn from foraging research to establish a method …

Holocnemus pluchei spiders (Family Pholcidae) facultatively live in groups: sometimes they live alone and sometimes they share webs. In the field groups vary in size and composition and include spiders of all ages and either sex. Group membership is flexible and individuals move frequently among groups. To understand group formation and maintenance it is necessary to understand the costs of group membership. We used focal animal sampling to investigate the cost of group living for spiders of different ages across a range of group sizes. Both spider age and group size affected the costs incurred by group-living spiders. There was …
