New study: Humpback calves require 38 times more energy after birth
The energy required for newborn humpback calves to grow after birth is 38 times greater than what they needed inside the womb according to research from University of Hawaiʻi at Mānoa Hawaiʻi Institute of Marine Biology in collaboration with Alaska Whale Foundation and other key partners. These findings were published in Marine Ecology Progress Series.
Humpback whale mother-calf health assessed using drone tech
University of Hawaiʻi at Mānoa Hawaiʻi Institute of Marine Biology biologists used drone imagery to understand how nursing humpback whale mothers and their calves fare as they cross the Pacific Ocean. Recent declines in North Pacific humpback whale reproduction and survival of calves highlight the need to understand how mother-calf pairs expend energy across their migratory cycle. The study was published in “The Journal of Physiology.”
Mānoa: Pregnant humpback whales’ energy needs increase when fasting during migration
A new study shows proper intake of food is essential for pregnant humpback whales to pull off the extreme physical feat of annual migration between Hawaiʻi and Alaska.
UH: Humpback whales may steer clear of Hawaiʻi due to climate change
Humpback whales may one day avoid Hawaiian waters due to climate change and rising greenhouse gasses, according the findings of a new paper published in Frontiers in Marine Science by a team of researchers including three University of Hawaiʻi at Mānoa graduate students.
