Predicting Survival From Social Network Metrics In Bottlenose DolphinsStanton, Margaret A.; Singh, Lisa O.; Mann, JanetFriendship networksCentrality, Alliances, Animal Networks, Affiliation Networks, Friendship FormationWED.PM1In human and non‐human studies social network analysis is rarely linked to critical biological parameters such as survival and reproduction. This studyaddresses the potential relationship between sociality and fitness in wild bottlenose dolphins. Although social complexity is presumed to persist because itincreases survival and reproduction, few studies have empirically tested how individual social variation relates to fitness. Like humans, bottlenose dolphinssociety is characterized by compositionally and temporally variable groups (high fission‐fusion). Since both sexes remain in their natal range as adults,important social relationships may form early and persist later in life. Using the extensive 25 year Shark Bay Dolphin Research Project dataset we employ socialnetwork analysis to determine whether early social patterns predict juvenile survival. In this analysis, the survival status of 56 juvenile dolphins with >20sightings serves as the binary response variable in a rank‐order logistic regression with calf sex and network metrics including degree, strength, betweenness,eigenvector centrality, and clustering coefficient as explanatory variables. Sex segregation in adult behavior suggests that different metrics have differentpredictive capabilities for males vs. females. Inquires that incorporate network theory into traditional hypothesis testing are imperative to increasing ourunderstanding of animal sociality and behavior.Professional Networks Of Underrepresented Minorities In Science: Building And Accessing Career Resources In Early Career StagesPinheiro, Diogo L.; Melkers, JuliaAcademic and Scientific NetworksAcademic Networks, Underrepresented MinoritiesFRI.AM2Minority faculty are dramatically underrepresented in science. Qualitative studies of minorities in the workplace point to evidence of exclusion, andqualitatively different experiences in the work environment. Yet, little is known about how these factors matter in the structure and resources of professionalnetworks of underrepresented minorities (Blacks, Hispanics, and Native Americans). Most studies have focused on work environment issues, and little is knownabout minority networks. Do underrepresented minorities develop different career‐oriented networks than the majority? Are the structural aspects ofunderrepresented ethnic minorities more similar to those of other underrepresented groups, such as women? What explains patterns in racial homophilyamong minority scientist’s professional networks? Based on data collected as part of an NSF‐funded national study of academic scientists, this paper reportsfindings regarding the structure, composition, and career resources in the professional networks of minority academic scientists. Preliminary results using aseries of explanatory models and statistics show that although minorities do not have significantly different network sizes, they do differ in terms of networkcomposition and resources. More specifically, minorities tend to have larger collaborative networks outside their current institutions. Related,underrepresented minorities are much more likely to have met close collaborators at academic conferences.
