Escorting Of Mother-Calf Pairs Of Humpback Whales (Megaptera Novaeangliae) In The Colombian Pacific During The Breeding Season, Natalia Botero Acosta
Escorting Of Mother-Calf Pairs Of Humpback Whales (Megaptera Novaeangliae) In The Colombian Pacific During The Breeding Season, Natalia Botero Acosta
Dissertations
Humpback whales (Megaptera novaeangliae) belonging to the “breeding G-stock” annually migrate from the Antarctic Peninsula and southern Chile to the southeastern Pacific to reproduce. Associations between mother-calf pairs and escorts were examined in the Gulf of Tribugá, northern Colombian Pacific, using photo-identification and behavioral/spatial sampling. Research hypotheses included: 1. The association between cows and escorts is short-lived, consistent with a male reproductive strategy, 2. The presence of escort(s) elicits a behavioral response from mother-calf pairs and, 3. The patterns of spatial distribution reflect the spatial segregation of maternal females. Groups were classified as mother-calf pairs (Mc), mother, calf …
Evaluating Social Network Dynamics Of Bigg’S Killer Whales (Orcinus Orca) And Vessel Traffic Within A Transboundary Region: Implications For Conservation Management, Courtney Smith
Dissertations
The social lives of animals are defined by group dynamics based on the nature and strength of associations and movements between individuals, often resulting in highly complex and interconnected social networks. However, understanding of how environmental variables may shape this structure is poorly understood. Within the inland waters of Washington State and southern Vancouver Island, British Columbia, mammal-eating Bigg’s (transient) killer whales occur in relatively small, but stable social groups. Group size and occurrence in recent years has increased, coinciding with a growing whale watching industry. Given the central importance of the social network within killer whale population dynamics, such …
