Where eagle rays spread their wings in US waters

Until recently, the geographic wanderings of the whitespotted eagle ray have always been a mystery.

Now, in a study that took place from 2016 to 2018, a team of researchers have started to unlock some of its movement patterns.

The 54 rays in the study were tagged with acoustic transmitters, along both the Gulf of Mexico and the Atlantic coast of Florida, using collaborative acoustic telemetry networks.

The fin whale, also known as the finback whale, is the second-largest species on Earth after the blue whale.

Whales expand their distribution

Four of the six baleen whale species found in the western North Atlantic Ocean (humpback, sei, fin and blue) have changed their distribution patterns in the past decade.

Using 281 passive acoustic recorders moored to the sea floor from the Caribbean Sea to Greenland, researchers from the United States and Canada monitored the movements of the whales from 2004 to 2014. The findings of their study was published in the Global Change Biology journal.

Natural bleaching susceptibility is manifested in the biochemistry of both the coral and its algal symbiont.

Unravelling how some corals resist bleaching

Researchers at Michigan State University and the University of Hawaii at Manoa have been uncovering clues as to why some corals bleach while others are resistant, information that could help reefs better weather warming waters in the future.

The team analysed the biochemistry of corals using mass spectrometers to understand what set resistant corals apart from susceptible ones. The scientists found that two different communities of algae lived within the corals. Inside the algae cells were compounds known as lipids.

Researchers conclude the northward range shift demonstrates the young white sharks are being subjected to a loss of suitable thermal habitat

Climate change shifts the range of white sharks

Researchers conclude the northward range shift demonstrates water temperatures within their preferred temperature range of juvenile white sharks are becoming harder to find.

The animals have historically remained in warmer waters in the southern California Current; Between 1982 and 2013, the northernmost edge of the juveniles' range was located near Santa Barbara (34° N).

The first Barracudas entered operational service on 10 January 1943 with 827 Squadron of the Fleet Air Arm (FAA), who were deployed in the North Atlantic. Eventually a total of 24 front-line FAA squadrons were equipped with Barracudas.
