(2009-05-15)This thesis examines the characteristics of dusky dolphin (Lagenorhynchus obscurus) nursery groups and ontogeny of dusky dolphin calves. Data were collected via boat-based group focal follows of nurseries from October ...
-
(Texas A&M University, 2004-09-30)Foraging theory suggests that hungry animals balance a complex set of costs and benefits when determining what and how to eat. Prey distribution, patch size, and the presence of conspecifics are important factors influencing ...
-
(2009-05-15)Interactions between humans and dusky dolphins in the coastal waters of New Zealand are increasing. My research focused on tourism interactions, with Kaikoura as the study site; and, on habitat use in an active aquaculture ...
-
(2011-07-14)I characterized dusky dolphin (Lagenorhynchus obscurus) underwater bait-balling behaviors and acoustic signals, and compared data between Argentina and New Zealand (NZ) to investigate the roles of ecology versus social ...
-
(2009-05-15)The distribution, behaviours, and composition of dusky dolphin (Lagenorhynchus obscurus) nursery groups off Kaikoura, New Zealand, were examined. Data were collected during January–May 2005 and December 2005–April 2006 ...
-
(Texas A&M University, 2007-04-25)The sex of and genetic relatedness among interacting individuals are known to be biologically fundamental features that characterize the composition of animal groups. Current work continues to illuminate reasons for the ...

(2018-05-29)This dissertation contributes to our understanding of anthropogenic effects on wildlife, a central question in the growing field of conservation behavior. I present three case studies of coastal delphinid species in diverse ...

-
(Texas A&M University, 2008-10-10)I examined fission-fusion sociality in dusky dolphins (Lagenorhynchus obscurus), and investigated aspects of social convergence between dolphins and great apes. I used boat-based group focal follows and photo-identification ...
-
(Texas A&M University, 2006-04-12)This study presents evidence from mitochondrial and nuclear loci that there is genetic divergence among and within geographic populations of Lagenorhynchus obscurus. The effect of seasonal variation on the genetic structure ...
