High‐speed chases along the seafloor put Bryde's whales at risk of entanglement
Autor: Paolo S. Segre, Jacopo di Clemente, Shirel R. Kahane‐Rapport, William T. Gough, Michael A. Meÿer, Amanda T. Lombard, Jeremy A. Goldbogen, Gwenith S. Penry
Publikováno v: Conservation Science and Practice, Vol 4, Iss 5, Pp n/a-n/a (2022)
Abstract Recent changes in the South African marine ecosystem and the introduction of an experimental octopus fishery have resulted in an unsustainably high rate of fatal Bryde's whale entanglements. Using suction‐cup attached bio‐loggers, we ide

Future Directions in Research on Bryde's Whales
Autor: Rochelle Constantine, Takashi Iwata, Sharon L. Nieukirk, Gwenith S. Penry
Publikováno v: Frontiers in Marine Science, Vol 5 (2018)
One of the lesser known species of baleen whales, the Bryde's whale, also known as Eden's whale (Balaenoptera edeni edeni and B. edeni brydei), although hunted as part of a North Pacific Japanese research programme1, was not heavily exploited by comm

Clear waters: assessing regulation transparency of website advertising in South Africa’s boat-based whale-watching industry
Autor: Minke Witteveen, Gwenith S. Penry, Mark Brown, Caitlin Judge
Publikováno v: Journal of Sustainable Tourism. 29:964-980
Long-term sustainability of South Africa’s boat-based whale-watching (BBWW) industry requires any desired growth to be achieved within sustainable parameters. Given that advertising is often the fi...

Baleen whales influence their ecosystems through immense prey consumption and nutrient recycling1–3. It is difficult to accurately gauge the magnitude of their current or historic ecosystem role without measuring feeding rates and prey consumed. To

The considerable power needed for large whales to leap out of the water may represent the single most expensive burst maneuver found in nature. However, the mechanics and energetic costs associated with the breaching behaviors of large whales remain

The Indian Ocean humpback dolphin was recently uplisted to ‘Endangered’ in the recent South African National Red List assessment. Abundance estimates are available from a number of localized study sites, but knowledge of movement patterns and pop

The scale dependence of locomotor factors has long been studied in comparative biomechanics, but remains poorly understood for animals at the upper extremes of body size. Rorqual baleen whales include the largest animals, but we lack basic kinematic
