Deep sea sharks are buoyant

Shark with tag

Scientists from the University of Hawaiʻi at Mānoa and University of Tokyo revealed that two species of deep-sea sharks, sixgill and prickly sharks, are positively buoyant—they have to work harder to swim downward than up and they can glide uphill for minutes at a time without using their tails. Their results were published in a recent study,“Unexpected Positive Buoyancy in ...

Plants may run out of time to grow under ongoing climate change

Corn at Waimanalo Research Station Open House

A key potential “benefit” of global warming — namely, that plants at northern latitudes will thrive in a warmer world — is challenged by a new study released by University of Hawai’i scientists. The prevailing assumption ignores the fact that plants in the North will remain limited by solar radiation, curbing positive effects of warming and additional CO2 availability. In ...

[VIDEO] How to train your coral

Coral

Scientists warn extreme sea temperatures could cause a “historic” coral reef die-off around the world over, following a massive coral bleaching event in fall 2014 in the North Pacific. A huge swathe of the Pacific was affected, including the Northern Marianas Islands, Guam, the Republic of the Marshall Islands, Hawai‘i, and Kiribati. Some areas recorded serious bleaching for the first time, and ...

Researchers from UH Mānoa and colleagues found that microbial communities in different regions of the Pacific Ocean displayed strikingly similar daily rhythms in their metabolism despite inhabiting extremely different habitats – the nutrient-rich waters off California and the nutrient-poor waters north of Hawai‘i. Furthermore, in each location, the dominant photoautotrophs – light-loving bacteria that need solar energy to help them photosynthesize ...
