Preserving seagrasses in a changing climate
This study provides the first comprehensive global assessment of how climate change may affect the distribution and range of 66 seagrass species. It also examines how well the current global MPA coverage will protect these important ecosystems in the future. The authors relied on occurrence records from OBIS, along with other sources of data and expert knowledge, to develop species distribution models under various scenarios.
Detecting sperm whales in the eastern Canadian Arctic as sea-ice continues to melt
Marine environments in the Arctic regions continue to be altered due to prolonged durations of sea ice absence, as a result of climate change. Seasonal shifts of habitat use occur as warmer, ice-free regions become available to many ice avoiding marine mammals. In this study, authors combined collected sighting- and acoustic data, including whaling records accessed through the OBIS database, to explore the range expansion of the ice-avoiding sperm whale in the Eclipse Sound area, Baffin Bay. Sperm whale presence in Eclipse Sound is a recent phenomenon, with only two sighting records of these mammals in this region, in 2014 and 2018, respectively. However, acoustic recordings reveal that sperm whales are present in this region yearly between 2015 and 2019 and that there has been an increase in sperm whale presence over the 5 year study period, closely related to the minimum sea ice concentration of each year.
Some fish go deeper to cool off in warming seas
A study published in the journal Nature Climate Change using OBIS data showed how fish, demersal and planktonic communities changed as warm-water species increase and cold-water marine species become less successful due to climate warming.
The great dying at the end of the Permian linked to ocean warming and oxygen loss
A study published in Science using historical data of ocean warming and oxygen loss, combined with species traits and occurrence data from OBIS revealed patterns of habitat loss and extinction at the end of the Permian period.
